First time out with the FC
 

20psi. S5 street port. OSGiken twin plate, T66 96a/r p-tim, SSAC front mount with water injection. 225/50/15 BFG drag radials. (old and 95% worn out) 2715lbs with me in the car. Right lane.

i wish my car ran 11's. not bad dude

fair play mate going good. i want to get mid twelves this year (might need some help i've got a tow rope)

Nice MPH :icon_tup: with a better 60' that car could see 10's no problem.
well done.

Here's a few vids of the run.
http://www.putfile.com/sleeper7
You can see I was shifting slow at 7000rpms. The motor only had 1-1.5 hours of run time since put together so I was taking it easy.

I think the next time out it will do a 10 second pass, hope anyways. (Now that I said that, the motor will let go.) Replaced the OSGiken twinplate set up for the heavier stock flywheel with ACT clutch kit. Also replaced the rear tire. from some worn out BFGs to MT Streets. Also got some good rear shocks on it now. also increasing the boost to 25psi. But keeping the tune at 10.2afrs.

good good

nice car, im amazed at how well those afrs are.

The gauge thats in the lower right is not the afr gauge, it's the air temp gauge. Sorry. I mounted the air temp gauge sensor in the LIM to see how well the water injection was working.
The afr gauge in on the gauge cluster. The three in the middle are, from left to right, fuel pressure, boost and egt.

where in sa are u

damn.. Too bad you aren't in Tucson, I could use some competition.

Can I ask why you swapped out the OS giken clutch? I've got the same twinplate in my FC I think (although its 6 puck and unsprung). It's a bit of a prick to drive, but seems to cope with any abuse I can give it.. it's only got about 2mm of meat left on it, so I'm deciding whether to rebuild it or to go with something else.

Weight of the stock flywheel is better suited for drag racing, IMO. For street stuff the OSGiken is great. Just did'nt like it at the track.

J-Rat, anything big happening your way over the summer. 1/4 mile?

Nothing noteworthy except NOPI in Phoenix in March. Tucson's drag way is the worst in the country, bar none. My car may be at NOPI, assuming the roll bar, new turbo, and other goodies are ready.

buy that bobo bolt in roll cage from ebay...

OH and how r you running to much boost without... controlling timing....

20 psi on a t66 without timing.... is that safe?

^^^

Translation please?

Translation:

You should get that the bolt-on roll cage that someone sells on EBay.

Oh, and, question: How are you running so much boost, with no timing control?

20 psi on a T66 doesn't seem safe without a way to control timing.

I cant speak for the thread starter, but I am sure he is on an EMS like me. They have timing control.

Bolt in cages are NOT NHRA legal.

Hey J-rat I thought you were going to come out to california for some competition.
What happened to that?
I know of a couple quick 7's out here.

No timing controll for me. SDS is a fuel only ECU. I use a unlocked 1st gen dizzy.

that's what i did for a long time in my old turbo 12a setups :) worked fuggin great!

I have always liked when people use those 12-t distributers. I bet it does work great!

Nice!

No 12a-T dizzy. just a stock n/a one.
The stock dizzy has a full mech advance of 19-22 deg. So if you set your timing on the leading marks of a turboII crank pulley which is -5before TDC. Your total advance will be in the area of 14-17deg Before TDC. I run between 17-21deg before TDC at 20 and up PSI. Been doing this for years.

exactly! there is no point in trying to locate a 12a-T distributor... a non-turbo 12a one is best :D

well crap. how reliable is this? i might just grab me a dizzy and build me a ginnypig engine=)

I set my timing at 4000rpms when the mechanical advance is at it's max (18deg BTDC) and let the idle timing fall were ever it wants. I do not use the vacuum advance part of the distributor.
Can't get any easier than that.

YEP good "old" technology, will get you there w/ no problems!!

go get that 10 sec timeslip, bet ya get off the gas he he he he he :Kill1:

New best time tonight
 

Broke 100mph in the 1/8 and 130mph in the 1/4. Only 11.5 with a 1.87 60ft. I need to work on the suspension. 10.7afr and 1.7bar/boost. Not sure if I want to lean it out or add more timing????

nice!

still using drag radials?

Update!
 

10.91 at 133.93 mph with 1.74 60ft... spinning 3rd gear..

WOW!! awesome man

which SDS you running? EM2 /3/4?
better get in on the future DSS 300M upgraded axle/hub-stub upgrade :)

ps

more vids plz :D

___________
11.59@99

also what was your 1/8 time on the 10.91 pass?

EM-3 SDS

On the 10.9 pass the 1/8 mile times are 7.1 at 101.97

your easily in the 6's for the 1/8th if you can maintain some damn traction! AAHAHAHAHA!!! i can't wait to hit the track :D i'm shooting for 10's with the a/c on! LOL

In car video 10.91et
 

http://www.rcmracing.org/amupload/10.9133.93.wmv

shift light on at 7100rpms. boost gauge is middle one on the dash. watch the wall when I shift into second gear. car goes side ways real fast. Shifted in to second gear late, around 8000rpms. Rear tires are MT ET street at 14psi. 60 ft time was 1.74. I lost by .068 of a second.

The poping at the start is not me. I don't two step.

new incar video 10.8et 1.54 60ft
 

http://www.youtube.com/watch?v=g8V5c_V9VAc

did not proof read the title before posting video. it's 60ft not 50ft.

what is your mph on those runs? i love how you keep getting faster man and those 60ft's are insane! i'll have some video's for ya in a couple weeks ;)

MPH was down, 130. Shifting to early I think cause the mph to go down. My shift light comes on at 71-71 hundred rpm and it did not come on during a few shifts. I think the et came down due to my 60ft and not spinning tires when shifting to next gear.

I need a bigger hot side for more power! still running a street port ( no pins ) and stock running gear.

so how much boost you running now? 25psi on pump and water injection? :D

I use 108 octane fuel, C12.

water is two M5 nozzles that come on at 5psi and full on at 25psi. pump is a 150psi shurflow pump. Devilsown controller.

Boost in first is 20psi
second was 23psi
third is 25psi
fourth was 25psi and dropping to 20psi.
All #s are +/- a lb or two.


Looking at adding another waste gate to allow the motor to breath easier. Then maybe the boost wont fall off in 4th gear.

awesome man, i was just curious. i'm turning mine up to around 25psi next week. maybe i can hit the same times you are ;)

Dude....get some bias ply front runners before you kill yourself. Your all over the track. It is totally unsafe running fat radial tires with the bias ply ET Streets. I am using some Firestone 16 inch skinnies mounted on FC spare wheels. After mounting those the car tracks as straight as an arrow.

Nice runs!

Andrew

Damn.. I need to get a full pass off in my car. My 1/8th MPH was 102.

Nice passes though! You really ought to quit lifting on your shifts!

flat shifting for the win!

andrew, really! Some one offered me a set of front runners just the other day. Thanks for the info.

J, lots of folks say the same things about my shifting, slow and at a too low rpm.

Currently adding another wastegate to see if my boost will hold at 25psi. I like to think the FC can do a 10.6et and 136mph with it's current mods. Hoping the added gate will allow more cfm go through the motor for more power. Then hope for a low 10 second pass.

30psi and 9's ;)

I wouldn't say slow, but you can definitely tell you are losing some time due to re-spool. But thats just my opinion. Some people don't like to speed shift, it really is hard on the transmission. Plus if your transmission isn't in good shape, you will get locked out of the gears.

On a side note, is there any reason your AFRs are in the mid-tens?

AFRs in the low 10s.. Trying to get it to the high 10s but the power is there with afrs in the low 10s, why go to what everyone think/says the best power is, 11.5. When I do get it on the dyno I will try to tune to a leaner afr, it's hard to monitor at the track. Running low 10s afr and shifting at 7200rpms may extend the motor life. With the water injection, the motor is clean and preventing carbon build up from the low afrs.

Just installed another waste gate to see if my boost will hold at 25psi. If this works, then the boost will go up a few lbs. Now running two 38mm gates. Looks like rain this week so #s will have to wait a week or so.

Uh, thats not what EVERYONE says, its been PROVEN. But you are right, if your power is there and you are happy with it, press on. However, with water (or alcohol in my case), 10.5 is ridiculous safe.

J,

How much more power is 11.5 vs 10.5? I know leaner is faster but wondering how much faster is the 1 point afr. And how much more "stress" it puts on the motor? And my timing, will I have to retard some? right now it's at 20deg BTDC. One of the other things I think about when trying to tune to 11.5 is that leaves my tuning margin very small. Trying to tune at the track is a little crazy anyways, guess I'll have to put the thing on the rollers.
thanks
