I went to the track for the first time this year, this past tuesday. I tried gate shifting like the majority of people use and I had worse times then when I use ss mode. I don't know if it's because I have the new trans and ecm. The problem was, when I gate shifted it took the trans at least 500-600 rpm from the time i moved the shifter before it actually shifted. In ss mode it takes 200-300 rpm. I was wondering if this was common or not.

I ran (2) 15.0's in gate mode and (2) 14.8's and a 14.9 in ss mode. I still get too much wheel hop so my 60 ft times are 2.3-2.4

 

I think you just need to get used to gateshifting. I've run my best time gateshifting (14.6 @96) and I have fewer mods.

 

 

Your trap speed is pretty good. Could be higher. Although with my new tranny while I'm gate shifting it doesn't take 500-600 rpms. More like 200. With the new tranny my shifts are very quick. No slippage at all. Keep up the practice.

 

My traps were low because I didn't check the tire pressure and found them between 22-25 psi all around. I'm going tomorrow so we'll see.

 

Ferizzo I usually run my fronts around 23 PSI. I raise the rear to 40. Try that.

 

u should be quicker with your mods, use gate shift and get as close to the limiter w/o hitting hit

 

How did you get a 14.6 @ 96 and I got a 14.863 @96.69

This is one thing I could never understand when people have the same trap speeds, but different times.

heres my slip
r/t .403
60' 2.327
330 6.381
1/8 9.645
mph 73.95
1000 12.487
1/4 14.863
mph 96.69

 

It's all about your 60'. I usually pull off 2.1 60' times. Sometimes I'm at like a high 2.29x. I always trap at 98 MPH but my ET varies a few tenths.

.1 off your 60' = .2 off your ET.

 

Empty out yo car, and lower that Air Pressure. Humidity and all that shit come into factor also.

 

Don't bother removing the spare tire, jack, tools, etc. It doesn't make a difference.

 

all that weight is in the back, it does help to take it out

 

Good question. The answer has to do with my tire pressure being so low in the back and my 60' foots sucking. Best I've gotten is a 2.3x (2.35 or 2.38) so I can improve there. Judging by others' times with similar mods I think my car is capable of a 14.4 @97 because with even a 2.25 60' I should get close to a 14.4.

 

It is like 40lbs. You might gain .05 off your ET.

He needs to focus on his 60' time.

 

Also, did you check to see if your IMRC is working properly?

Your 1/8th mile trap speed is 73.95 MPH. Mine is usually 77 MPH.

What was the temp and humidity? Elevation of the track?

Last time at the track I got a 2.313 60' on my first run but I still trapped at 98.51 MPH. I have I/H/E

 

I never took mine to a track but anytime I raced i just left the thing in D4 or D5 and it did just fine by itself.

 

Leaving it in D4 or D5 is fine for racing from a roll.

But from a stop, if you are fighting for traction, the tranny will not always hold 1st gear to the redline. If you shortshift or hit the limiter on the 1->2 shift not only will hurt your entire time. I've tried ONCE to leave it in D4 and just run. I still pulled off a 2.1 60' time because I get excellent traction off the line. But I felt like the transmission didn't hold each gear out to its full potential (new tranny/PCM possibly??) When I gate shift, 1->2 comes at 7100, 2->3 comes around 7300.

 

gateshifting is the only way to fly for the 1/4.

 

Well today was a shitty day at the track. I got three runs in and I was a consistent 14.8 @94-95mph. Had 2.3-2.4 60' times all day. Not sure what to think except that it was hot (3rd run the temp was in the low to mid 80s. First two it was mid to high 70s. My icebox hasn't been cleaned in 10k miles. On the bright side Evos were running low 14s all day (one ran a 12 something though). SRT-4s were running high 14s to low 15s (couple I saw broke into the 13s.

 

Hmmm... never dragged an auto-CL before

 

its pretty easy

 

Don't forget to go around the water box if possible unless you have drag radials

 

I usually just keep it in D-5. Even with me best of 13.68 @102.56 was in D-5. In WOT the tranny goes all the way to red line so no problem. This gives me the opportunity to focus on driving and not worry about shifting. Human error/judgment on shifting is risky and not very consistant.

 

Thanks for the help guys. One of the big problems with my car is weight. Last summer at the Byron drag strip my car weighed in at 3675 with me in it and I only weigh 162lbs. I also just try to see what my car would do on the street so at the track I don't mess with pressure or taking the spare out. The temp that night was 53 I don't know elevation or humidity.

 

You don't count. You CL-S is far from the normal! :o

 

Hey mrsteve hate to ask a stupid question, but what is IMRC?

 

Just curious do run the stock or high boost comptech pulley?

 

http://www.acura-cl.com/forums/showt...hreadid=139353

 

I thought that was what you where meaning. I always referred to it as the intake actuator. I haven't checked it in a year or so.

 

It's the high boost pulley. I should be getting the Payntech pulley this week+2-3.5 more lbs.

 

I think it does count and my car is a TL with a trailer hitch.

 

I only said you don't count because you aren't running the stock transmission and thus your shifting might be different.

Hey, any problems with the VSA and your new tranny? I thought I saw a post where someone was having issues.

 

Nice! I assume you have the e-manage then? How much boost are you putting out with the high boost pulley?

 

The Comptech HBP is about 5.5 lbs. The Payntech might net 7.5-8 I'm not really sure I talked with Tom at PT yesterday and there is only one out there that is running but no report/results. As of yet I do not have the e-manage. We're going to run the pulley first and test it as my last air/fuel mapping dyno indicated that it was very rich. With it being so rich it might be ok with the extra 2+- lbs.

 

I think you may have some issues with that. I would check with modaddict or scalbert before you try it. In any case let me know how it works. I am getting about 5.5 pounds of boost also with my HBP.

 

8 lbs with an engine running such a high CR like ours!?! Good luck man.

 

Our engines under that CR may handle up to 9lbs. max. We'll be doing install and testing either Tuesday or Wednesday of this week. We will have to make sure that it doesn't run lean. If all goes well it will be taken to the track and then a dyno run.

 

Good luck man, can't wait to see the results

 

Even tho it's not much on the time, I believe your net improvement will be better because of weight transfer. By that I mean you are taking weight off the back end which may have some minimal impact on traction because we are frt wheel drive.

At least that's what I seem to recall. I'd bet there is someone that's more of an expert than I am at this that can tell us otherwise. :P

I know it can't HURT that's for sure. But its not worth the effort really. Lower the front tire pressure, raise the rears, you'll be set.
