Haven't read all of the posts but flooding could be not letting the car run long enough. Mazdas accelerated warm up bumps the RPMs up high to warm the car. From what I read if the car is shut off during the process or before the car reaches temp. IE moving it a few blocks in cooler weather won't hit temp and when you shut the care off it may flood when you turn it on. This used to happen to me in NE during October/November driving. I would flood like once every week or so

thanks for the tips FCJG15 but i can rule that one out straight away. the last week has been spent trying to adjust the TPS so every time i have started the car i have taken her for a 20 minute drive to get her warmed up.

Lars (ARVIKA) had sent me a pdf with the procedure for adjusting the tps so armed with two multimeters i went out and tried to adjust her using the volts method as suggested by clokker. i got nothing again. after plaguing poor lars with numerous questions and pictures on facebook messanger he came straight from work to help me!
i have been pulling the egi fuse to stop the car from flooding and doing the tests without it in. never even thought about it till he pointed it out. he basicly sorted out my tps and timing and had her singing like a bird. we then went on a test drive and she went better than she has ever gone. ten munutes into the drive she started running like poo. bucking and missing like nobodies business. lars thought that it seemed like it wasnt getting enough current and lo and behold when he checked the alternator, it was charging at about 12.5 volts. (for some strange reason i have managed to erase the term alternator from my vocabulary and keep writing 'generator' which is what its called in swedish. having to translate words from your second language back to your mother tongue using google just feels wrong) it was charging at about 12.5 volts. he took a closer look and noticed that one of the prongs on the contact tucked away right behind the alternator was very frayed and hanging by about two strands. he sorted that out and we went for another test drive. she ran really well! i thanked him for his help and like a rotary zorro, he did three doughnuts with his FB and drove off into the night!

its been really nice to have someone with so much experience with rotary engines give the seven a good looking over and not only help me to fix my current problem, (which i dont think i would have seen or worked out for a very long time) but also have a look at engine as a whole and confirm alot of things i have been worrying/obsessing about.

today there was going to be a car meet so i met lars and a couple other fellas and we drove together from there to the location through some excellent twisty roads. ill admit it, i was grinning like an idiot the whole way. it really feels like a milestone in this project to have her running as she should before the winter and then the day after get to have a spirited drive with a couple raspy 12a's. it felt good. really good.

when we got there we met another one of the fellas who had his fd and we spent a sunny afternoon chatting away about rotaries.




daddy duties called so i had to go home so i took slingerbultan. its a really nice road to take a spin on and very popular here amongst enthusiasts here and especially motorcyclists.


of course this project is far from over and there is much to be done, i have at least three pages on my to do list not to mention all the little extra things i consider doing to the seven all the time AND the fact that i still dont have any wheels. a winter without a garage will of course slow my progress but i shall try to do as much as i can outdoors while the weather allows and save some other bits that i can do at home for the cold months.

all in all, a very satisfying day!

Glad to hear that you've finally got her running smoothly! Enjoy driving her while the weather permits.

meerkat8701

will do placd1! im going to try to put her through the safety test next week so i might even get to enjoy driving her legally as well!

meerkat8701

I didnt see any reason not to so i booked a safety test for today.



I didnt get her through but here as long as its not anything too serious you get a month to drive so that you can fix them. as long as you come back within that period you pay a lower sum.

basicly i failed on some lights and my CO was a bit too high. as you can see it was 4.5% and 3.5% is the maximum which is not too bad. dont see why a bit of ethanol shouldnt fix this. according to the fellas i was at the meet with, because of the age of the seven they have made certain exceptions concerning emissions which is why they only check the CO.
looks like the brake balance was a bit off at the front as well plus my front registration plate was missing (i forgot to put it there)
just some small fixes and she's completely legal to drive! and for the next month i can drive around as much as i want without having to worry about the five-o

another interesting thing i found out at the meet is that in 2 years she will be 30 years old and reach 'veteran' status or 'classic' if you will.
this means i only have to do a safety test every 2 years and i wont have to pay any road tax!


its started getting right chilly in the evenings so i had better enjoy just driving her while i can

meerkat8701

although very pleased about coming to this point there are alot of things im not too happy with.
the alternator not charging enough. around 12.5 under load and from what i have read it should be charging 14. thats what the meter is showing anyway.. she still runs rich, (i have no proof of this but it REALLY REEKS of petrol) im still getting a little bit of backfiring and if i open the driver window whilst driving or at idle i get a lot of fumes in the coupe.
im wondering if these problems could be related? am i correct in assuming that if the alternator is not charging enough under load then it would affect my ignition? what i mean to say is that i would not get a very good explosion in the combustion chamber resulting in unused fuel making its way out of the exhaust? if this is the case im probably losing power as well... she runs well but i just cant shake the feeling that she could run better..

With the car OFF, use the multimeter to measure voltage across the battery terminals.
A healthy battery will read @12.5v or so.
Now, do it again with the car running.
If the alt is working right, you should see 14.5v or thereabouts.

If not, it's not the alternator "not charging enough", it's not charging at all.

Fixing the alternator will not fix the rich running condition.

meerkat8701

sorry for the belated reply clokker! i got a little under 14v when she was running so i geuss ill have to keep looking. now another problem has arisen or to be more precise cannot be ignored any longer. fumes. the fumes coming into the car are too much. if i open the windows they are overwhelming and driving the car for more than 20 minutes results in me feeling not so good. kinda unhealthy. the gaskets i got with the RB system were used and i have removed and installed it a bunch of times and i geuss they just aint doing theyre job anymore. ill be ordering all new gaskets from racing beat.

65 dollars...

for gaskets..

How many times did you hit the triple digit on your little drive? That would be MPH also.

meerkat8701

if you mean on slingerbultan not many tbh. that road scares the **** out of me. i had the gps on so i had a "map" of sorts to look at whilst i drove but some of those corners are tricky. it would be really nice to drive there more next summer to really get used to/lose respect for the course

Arvika

This film is good, but the "slingerbulten" is much more twisty and curved and have bigger differences in altitude than what the video shows.
I live about midpoint of it and do drive it daily with my stock engine FB. And the speed never exceeds 130km/h... I do hope though that I will be much faster next summer!

meerkat8701

i agree! video really doesnt do it justice. ill have to borrow my buddies gopro so we can do a run together. only problem is itll be a short video because youll have left me behind after a few corners hehe =p

Wheels?

TonyD89

iTrader: (10)

Oh I think I see a few places deep into the video where you're getting with it. I'm guessing at least a few times.

meerkat8701

im afraid that i cannot take credit for the driving in that video it was just a random video i found on youtube to demonstrate how slingerbultan looked. ill try to sort one out with the seven next summer! =)


i worked with robban this week and he hasnt been at the workshop for a while, working instead at the company we met so no progress as yet. he said he has one wheel left to spot weld then we'll send them off to a firm (which is conveniently opposite his workshop) for sandblasting and welding. i have a feeling that theyre going to take a while.

as the inevitability of the scandinavian climate draws near and my hopes to find a garage wane, im beginning to realise that i wont be able to get alot done on the seven this winter.

i drove the seven back and forth to work the last three days and i thought i had solved the problem with exhaust coming into the coupe but apparently not. even though the smell was reduced, the fumes are still coming in. after a 20 minuite drive i was feeling weird, coughing and slept for 12 hours straight. my girlfriend got super pissed off with me and i have been forbidden from driving the seven until its fixed. i think it had something to do with "not killing myself" being one of my responsibilities as a father. im going to clean and do the dishes more and order the new gaskets from racing beat and hopefully ill be out of the dog house soon whilst on the subject of small annoying problems, the hose to the expansion tank popped off, spraying coolant all over he place. i noticed that the coolant is a bit brownish so it looks like wasnt able to take all the rust out of the system. im going to have to use coolant flush a few times to at least try to reduce it.

finally getting to drive around in the seven the past few days has been fun albeit unhealthy and im pleased with the car as a whole. but there is one problem. she is definately lively but my butt dyno is telling me one thing. I WANT MORE POWER.
yup, it took a couple weeks and im already hungry..

so, after much consideration, i have decided on the next stage of this project. im going to supercharge her. i dont really mind if i dont get massive gains, this will mainly be to satisfy my aural fetish and get to listen to that nice whiny sound when i accelerate.

of course all of this is easier said than done. and my naivete concerning how much ideas like this usually cost is gone so i have already decided that the skyline has to go if im going to have the funds for this. i bought a family car the other day (a citroen berlingo, ugly as sin but spacious ) which means i have four vehicles. again. so the nissan's will be getting sold to free up some a dat munny. from now on ill be sticking to the "one daily driver, one fun car" rule.

so, the first thing i want to get is the blower but im having trouble deciding which one to get. there are roots,centrifugal and twin screw and its seems like the prices go in that order. arvika has recommended that i go for either a centrifugal or twin screw blower. what will really tip the scales for me is which one will give me power in the lower revs, ( i want instant boost!) and of course the price. twin screws are crazy expensive but im sure theres a reason for that. i have a feeling that robban will be instrumental in me pulling this off..

tips? thoughts?

well thats the plan so far. this thread will slow down a bit over the next six months but fear not my fine feathered friends, it shall not expire!

Well don't I feel stupid now.

In the seven(ish) years I've been here, I've seen the same Camden supercharger kit come up for sale maybe three times. If you wait, you could jump on that crazy train when it shows up again.
Or, you could ask Evil Aviator, who seems to know the subject.

meerkat8701

if its any consolation tony, imagine how stupid i feel spending all that money on a skyline gtr only to sell it for what will probably be less than half the amount i spent on the bugger so that i can spend it on a fc3s plus if you have read this thread you will see that i am in absolutely no position to judge anyone elses intelligence..

even i have run across some talk of this infamous camden kit on here.. accepting the harsh berating i am most likely to receive, i shall now proceed to outline how simple i think this is.

plan A

1. purchase supercharger
2. go to robban with a bunch of scrinkled up bits of paper with unintelligable
equations and drawings (like i did with the wheels) and get an adaptor made up from said supercharger to the intake.
3. speak to a supercharger specialist (one of robbans customers) to try to work out how big/small my pulley is going to need to be and get one made up for the supercharger/waterpump/crank/alternator and a nice fat belt for it.
4. sort out some kind of cooling solution if needed
5. engine management system. (im not sure if i would need to upgrade the injectors or fuel pump..)
6. get her mapped
7. get served divorce papers
8. as the final strand of hair falls from my head and the last moth leaves my wallet, collapse into a crumpled heap on the floor, mumbling vaguely about "i shoulda gone turbo" or something to that effect..

plan B

1. drive around in my n/a rx7 seven going "weeeeeeeeee" "weeeeeeeeeeeeeeeee" "weeeeeeeeeeeeeeeeeeeeeeeeeeeeee" so that it feels like i have a supercharger. trust me, it could work i have a really good imagination


have i missed anything?

clokker

iTrader: (2)

Indeed, you have.
Forget the supercharger and just put on a Gilmer drive system.
All the belt whine, none of the complications.

Why are you trying to load more work on Robban while your wheels are still unfinished?

meerkat8701

thanks clokker! that what exactly what i had in mind but i didnt know what it was called. gilmer system it is!
i actually already have a cool whine going on but unfortunately im pretty sure that it means that my pilot bearing is on its way out.

as for robban, all he has left to do at the moment is spot weld the last wheel ( i thought it was done but he hasnt been at the workshop lately) and then we will be sending them to another company for the rest of the work.

funnily enough it was probably robban that was most enthusiastic about me doing this and he offered to do an adaptor for me when the time arises. one of his customers is a supercharger specialist here and he has made quite a few parts for them so he has a bit of experience with it too. definitely an advantage where that stage of this project is concerned. i have had a little chat with arvika and he has given me quite a lot of advice and despite the levity in my previous post i have my heart pretty set on this. i have ordered a book which was recommended to me which i hope will broaden my understanding and help me to make a more educated plan when it comes to how i will put her together

the hardest part at the moment will be getting together the funds but with a bit of hard work and by flogging some skyline bits i should be able to get some wong together. (bit of east london slang there ) the amount i get together by the spring will ultimately decide whether i go roots or twin screw. because i have high compression rotors i wont be able to boost any higher than 0.5 bar and i have no intention of pulling apart the engine at this point just to change them out to lower comp ones. ( the next time i do this i will have my own house and garage and thats a promise ) which should mean that i probably can get away with installing an intercooled roots compressor.

as to things im trying to sort out before the snow falls, i have now ordered new gaskets from racing beat and thought that while i wait i can try to seal/make airtight the grommets/seals where exhaust can get into the car. im pretty sure the gaskets will solve alot of this but i want to be sure. i have actually felt like doo doo the entire week and have gained a whole lot of respect for the toxic properties of carbon monoxide.. i was thinking of using normal silicone but wanted to check with you guys to see if there was anything better that could be recommended apart from buying new seals.

i really really really dont want winter to come..

That is terrifying, yet you seem to find it encouraging.

As your winter eclipse approaches and the otherworldly cold freezes your internets, I fear the results that will emerge at the spring thaw.

after reading about this for a couple days and finding little to no conclusive information about supercharging a 6 port 13b, ill be spending most of the winter hibernating in my classily furnished scandinavian cave swathed in polar bear skins learning as much as possible before i spend a krona. i can admit that i have already felt the urge to go the 'simpler' route, ie not supercharging her. but i am a stubborn bugger.. sometimes to the point where i even exhasperate myself. im sure with some careful research, planning, and little bit of help from my friends i might just pull it off =]
but first... i must cure some narwhal meat and hoard nuts and berries. there wont be any supercharged 13b if i starve to death!

That alone should tell you something.

Is narwhal gluten free?

narwhal is gluten free and perfect for whatever the latest instagram fad diet is at the moment! #dieting #fit # cool # boy #girl and so on..

this was actually one of the cars that really got me turned on to the supercharger thing! the sound as he accelerates makes me proper pervy

i had a little chat with joel today and im probably going to sell the skyline in parts which is perfect because.. its already in parts. it still hurts a bit knowing that i spent so much money on it only to drive it around for a couple months in total over a duration of 3 years but life goes on and my life looks a lot different now than how it looked then. although the skyline was, in my opinion brutally fast (scary even), it wasn't as much fun and because of what i have learn't through working on the seven i feel like we have a much better rapport.
another fact is that the skyline is a way more expensive car to run, insure, tax and so on. i never even got it through the registration safety test so i was just driving around with english plates which, even though i got away with it wasn't fun at all having to pap myself every time a saw a police car. it just took the enjoyment out of it..
this is effectively the only way i would have a chance at raising the funds needed to continue with this and its nice that the skyline will be finally more than a bunch of heavy stuff that has to be carried around/parked/stored somewhere..
