you are right Mel, this camera sux. I will try to get a better one and also take the pictures during the day

 

no less than 4.5psi

 

Hey, you can't change your username! You will always be Wackoffracer. Oh, wait, theres' no more race left in this old horse anymore eh?

 

LOL you ***!! its still in me. you just dont see me coz you're a late bloomer.

 

Yeah, I know it's still in you.....my big white shlong!
Next time I go to the track, I'm going to make you come along and race one of your cars. You need to get back in the racing game you old fart.

 

one day...one of these days lol

 

Update.

Went to dyno today and just ran 1 pass to check my a/f values. Check the pictures and let me know what you guys think

Also the car performance was of only 110whp and according to my old visit to the same dyno the car had before 109whp with the stock carb but this is not accurate if we compare the old dyno's settings with the new settings, the dyno's settings has changed and if we take the same parameters that were used on my first visit the result is an increase of almost 5whp after installing the 48ida. I was hoping to get a few more hps but I guess that now is the time to tune this baby!!

EDIT: forgot to tell that my torque decreased compared to last time visit even when the parameters were adjusted

 

get your self another set of venturies (1 size bigger and smaller) and a set of index/number drill bits so you can just drill out the jets for tuning purposes. Once you find the right combo, buy the right size jets. Redline it on 3rd gear, shut off the engine, pull out the plugs and read them but first you need to learn what the color of spark plug means.

 

Thanks for your fast reply Mel, so you think that I should gain a few extra hps with just tuning the carb????

And taking your venturies advice I have to order 1 pair of 39 and a pair of 41's since I am using 40's correct?

Agreed

 

Okay a few questions. 1 what is the exhaust setup 2 how much timming were you running?

 

I will get back to you with the timing info, since I dont know quite well that.

I think the leading is at 20* dont know for sure the trailing but I heard that someone mentioned that my trailing is too retarded and needs to be advanced.

Will confirm those values for you.

Now the header is a racing beat that I bought dissambled from RB, it was poorly welded here in my country along with the complete exhaust that is crap, you can hear the exhaust leaks on the various videos I have loaded to youtube

 

since the torque peaks at 6000 rpm it makes sense that you're running a RB header they're great for street driving, but not optimum for all out HP. I'd bet the runners collect somewhere in the neighborhood of 28-30". The best thing you can do is to get that exhaust nice and free flowing that should bring peak tq up higher and net you more power. I made most hp with timming locked at 27* and AFR's targeted at 13:1. I'd first set the timming to 25* then see what your AFR's are at. IF they are still in the low 12's move to a 160 air corrector and that might be good for a few ponies.

p.s. I would start your dyno pull at lower rpm around 3000 RPM considering you're going to be making peak numbers at around 7k rpm. With your exhaust there's no point in revving it past 7500 rpm you're just hurting the engine. Plus it will give a broader view of what's going on.

 

You are damn right, plus the runners connect so shitty that it is even funny. I wasnt there when they made the exhaust for my car and didnt notice how the exhaust was done until later when the shop returned me my car back, I just wanted to have the car back since another mechanic burned me in the past during this project.

Anyways I will do what you say probably tomorrow and try again. When you mention that you had your timing locked at 27* you refer to leading right? What is the number that I should have the trailing at ???

Thanks.

 

Yea. I always use some split usually the trailing is about 5* after the leading. I made peak power at 27*, but I always back it down to just under 25* for daily street driving just to be safe incase I get bad gas. In my engine i made the same power with no split as with 5-10*, but I get better gas mileage with 5* so that's what I go with.

 

Dude! very nice... just do what your doing. its good too see a project coming along your on the right track just do it ... well done ... it brings back good memoryz of my first 12A Setup...

This was all covered on post #79 and #100 way back when.

NOferz............. tell me you have the timing checked and set already like we told you to do long ago? This is very important and the first step in tunning a car. For now just set leading to 25 and trailing to 20. You should already know how to check and set this up. If you don't know how to check and set timing, then by all means learn how to do it. If you need any help just give me a pm.

 

To be honest I didnt mess with the timing until this weekend when I went to the dyno again.

My timming is not set properly yet and I dont know that much about that so I am just going to send you a pm jay to get some valuable info from you regarding timing.

Thanks

Emir-

 

Ok, a lengthly pm just sent. Have a nice read.

 

Thanks for the pm Jay, I replied back

 

I wonder what is that all about. and nasty. i dont want to use my vivid imagination

 

lol Mel, he is just explaining me everything about rotary timings!. I wonder where would your vivid imagination take you if I didnt tell you what it was all about

 

Wacky's just day dreaming of my large white manhood again is all.

Ok Noferz, here's how you check if your front pulley is on right and how you check your stock timing marks, compliments of the wackster because I'm too lazy to type. https://www.rx7club.com/1st-gen-archive-71/ignition-main-pully-timing-525909/

 

Got it jay Thanks, Going to pull off the pulley tomorrow and mark the degs on it. I think I am going to order that summit timing light too
