Code3 + ASP 1/4 mile results...Your children should leave the room
Well it's pretty gruesome, but I figured I owe it to mankind to post my results one way or another. Let me just say that low-torque is amazing, and makes this thing move on the street. However, track results sucked! I will try to post up the time slips next week when I get back to work (where I left half of them... I just had to show off my disappointment to one of my coworkers
). I actually still can't believe it, as my trap speeds were the same as the ASP alone
Anyway, I left the best timeslip at work, but the 2nd best run went like this:
Atco Raceway, NJ
40*F
60' - 1.862 (best of the night was 1.80!)
330' -5.293
1/8 - 8.142 @ 86.46
1000' - 10.589
1/4 - 12.669 @ 108.34 (Huge W.T.F.???)
I think my best run was a 12.60x @ 108.xx. I was getting great launches w/ 1.8xx 60's on every run, and a best of 1.80x with my cheap Firestone Fuzion street tires (I love those tires)!!! I am definitely not making the power up top, though. Once the car hits 3rd gear, it starts to taper off. I just remember waiting and waiting and waiting for the car to sift to 4th (where it would get a good jump as the RPM dropped back into the sweet spot). Finally, it would shift about two seconds before the finish line. I should be hitting 4th gear much sooner.
B.T.W. I'm not counting this pulley combination out yet. I'm going to try to set something up with TVT Design and Jerry to see if I can get this on a dyno to get the tune dialed in for this set-up. I'm hitting 22 lbs. of boost, so the mechanical potential should be there. It should at least produce the power the 185mm pulley does, as boost levels are very similar, however my MPH is way off what the 185 guys are running!

you are probably maxing out the boost intake and ECU is probably not allowing to run at full power.
I would suggest to remove the CP3 intake to bring down boost.
To date, I have not see the best set up for a upper and lower pulley car.
Therefore you are in new territory....

The boosts are similar, however I do hit over 22lbs. Your mph is fine, I wouldnt worry about that too much. Your 12.6 is about right for your mods. Your only a couple of tenths off from all motor best.
What seems to me with all the data that I have seen is the c3 pully is great from the low end, and the asp helps with the top. You are still going to miss the top end of the 185.
I wouldnt be too disappointed with those results at all...thats about what I would expect.

The shifting thing is well known and all of us have that problem. It finally shifts a second or two before the 1/4. It sux, but what u gonna do.

Your DAs weren't mentioned??? Temp, humidity??
Anyway, this is almost exactly what I am running without a modded crank pulley at all. Only mods are a Code III intake, pulley and JerryTune. 12.7 @ 109.22. I don't believe that the crank pulley and the Code III is going to give us much more on "all motor" than what we already have. Jake is proof of that. I think to get below a 12.4 or so, we're going to have to go to the juice. Remember, the fastest right now is 12.3 and thats on the bottle.
You are only .3 tenths off the record on "motor only" so that's not a bad run. Or you could spend another $10K to Renntech it and still only run a 12.5. You're in the ballpark and in the hunt.
BUT hey, I'll take 12.6 or 12.7 all day long on motor only. Not many "street cars" on street tires doing that and that's exactly what you and I have done.

Yeah, sorry about that; the info wasn't showing on the timeslips correctly. It was showing as 0*F and 100% humidity all night, but I didn't see any snow
It was actually about 40*F, but I don't know what the humidity was like. Also, Atco is only a couple hundred feet above sea level (Actually a very fast track this time of year).

Nice numbers Eleventeen. I thought I was good with 12.9. Im jealous. Must get bigger pulley...must get bigger pulley.

I honestly don't think that's the solution. If we are all running at 18-22 lbs of boost with 22 lbs being absolute max, then we are pretty much "pullied" out. I am at 18 lbs without triggering a CEL, so I am more than comfortable leaving it at that. Car is reliable as stink right now, so no need except for cooling mods to push the limits. With good traction, I believe I have a 12.4 to 12.5 car and thats fine with me.

You’re running very quick and ought to be pleased with your progress and accomplishment, IMHO. Didn’t you get it up to 180 on your driveway the other day?
Your relatively soft MPH is perplexing, but that’s far better than a slug with a decent trap…like mine. There are several here who would be elated to record an all motor ET such as yours.
Discounting potential adiabatic inefficiencies that can occur at ~22 pounds of boost, that leaves only the omnipresent spark timing and mixture strength variables to tweak in order to optimize your existing combination. Any data logging and wideband information you could retrieve would be helpful with its diagnosis and optimization.
Congratulations on your outstanding times thus far. Well done.

I am running a 178mm ASP. If I had a 181 or 185 I would be faster. I aint pullied out yet, but wanna be.There is a difference between 18 or 22 lbs of boost.

LET C32 2002
Eleventeen install a belt wrap that C3P is making....I think you are missing air on top....does the car feel like it hauls at 3/4 throttle and a little less at WOT? Try it....if so my friend you may be missing air on top and its hard to Tune a car if the right amount of air is not there at the top end....I say add a LET intake to your C3P intake as Glenn did and it could add the air you need up top to Tune properly. 12.6 is a fabulous number my friend be proud
I read in another thread somewhere that increased air flow helps lowers boost is this right?

LET C32 2002
If Fongflex was able to do a 12.38 with just Rentech 178mm and software and on street tires then we all have a chance to get the same times or better...its practice, practice,practice launching as he did my friend and its possible

I also checked Dragtimes, and once I post up my slips, I'll have the fastest 60' time for a C32 at 1.80x. More practice can only help, but My E.T. is actually very good for the low MPH I'm hitting; I should definitely be trapping higher. If I could get 4-5 more MPH out of it (not too much to ask with these mods as this is where the 185mm guys are trapping with similar boost), I would be able to knock off several thenths. I'll get this figured out though. I kind of entered into uncharted territory with this set-up, so there is a lot to be learned and I DEFINITELY appreciate your ideas and suggestions so keep them coming;
There's something I'm missing here and I think this set-up has great possibilities once it is figured out. I'll definitely keep everyone posted on the results.

Unless you have upgraded injectors, and the proper tuning to utilize them, I would not drive your car at full boost. The simply fact is, your car is running dangerously lean. The car will make a TON of torque all the way to 4800rpm, then things get ugly. When LET did the tune for the dual pulley, they did not have any belt wrap setup. Because of the extreme amount of belt slip encountered, there doesnt initially appear to be any problems on the dyno. But once you add belt wrap into the equation, the tune can no longer compensate, and your injectors go static. Check out the dyno below. It has a tune + water/meth injection, and its not safe. We let off as soon as AF went through the roof.
On a different note, here is a dyno below with a mid size SC Pulley that I created. The dyno is a 178 + mid size. This is what I was working on for the 178 crowd. A sensible upgrade. The dyno below has no tuning. I put the overlay up from the stock 178 dyno. You can see it creates great additional power. +30rwtq peak +36rwtq curve - +15rwhp peak +30rwhp curve OVER the 178 on its own!

Brandon

Good thoughts; I guess airflow is a possibility, but I actually incorporated a belt wrap solution when I first installed this combo back in May. I get about 70% belt wrap and experience no drop-off of boost.

With my replaced sc intercooler I should easily be hitting 12 flat or very high 11's in good weather.
In actuality...4-5mph is a lot....
