For starters all I have done is the following: Comptech SC, Comptech Catback exhaust. I have a boost gauge and it confirms that it pushes 4-5 psi. Its about 3.5 psi under 4k rpm with wastegate closed, then hits 5psi at 4k rpm when the butterflys in the intake runners open and vtec changes over, allowing the surge in pressure.

So I took a ride to the strip over the weekend to see what this bad boy can do. Its all fun to talk about how fast your car should go in theory, but im all about actual results. So I went with a couple of guys at work with some crazy muscle cars that were unbelievable (low 10's). These guys were all "yeah you'll probably pull 15's maybe high 14's" I didn't argue I simply stated that I thought I would do better, they doubted me.

Third run, I am up against an 05 Mustang GT who's laughing as he looks over so I am determined to embarrass this dbag. Now knowing that the track will allow full throttle in first gear (tracks are much stickier than street), I figured half throttle launch feathering the clutch, then full throttle once engaged. Light goes green, I get a decent launch (could still be better) mustang jumps ahead of me about a car. As soon as i shifted into 2nd, later. Blew past him. Third gear, even stronger pull away from the mustang. Pulled a 13.86 putting the mustang owner to shame. mustang ran 14.22. I always wondered how I would do against one of those new gts. God if only this car was rwd! Yeah but then winters would suck i guess.

This was on michelin pilot sport ALL SEASONS! and 85 degrees. I think with cooler weather a j-pipe w/3rd cat delete and better launch, i can get even lower. Its all about the launch and shifting. I have had plenty of practice in my car and can execute lightning quick shifts. Anyone else done any runs yet? I thought I saw someone post a time somewhere.

 

here are a bunch of mods that would increase you times:
J-shift pre-cat deletes
ATLP J-pipe
Stock sized UR lightweight pulley (this will reduce weight from the driveterrain thus making you car rev faster)
ATLP Test pipe
AEM CAI modded for S/C
Lightweight battery
removing the floor-mats
removing manuals, etc

 

does changing the cai that comes with the sc kit really make that big of a difference? Ive asked on here before but got no reply. Im not too into removing stuff thats in the car when i drive it just to get a better time. If it was strictly a race car than i would. but i drive it daily.

 

I definitely suggest a JPipe and JShift precat Deletes. Good kill though

 

I would've thought a supercharged 6MT would do better than 13.86, what was your trap? @ GT running a 14.2

 

nice run

 

hmmm..im curious to see how mine will do now too..
though i know a sc should run in the mid to low 13's...

a friend of mine has a 08 type s 6mt with straight pipe and intake and he ran a 14.2

so...sc should be at least 1 sec faster

 

13.86@101.7- I thought this was a pretty good run for this car. The numbers you see in test mags are bs i think. This car is considerably faster when the air temp is cool and it was 82 out that day and the blower was very hot. The knock sensors really pull the timing back hard when the air is hot to protect against detonation. The car definately didn't feel its fastest. I believe when I go again in the next couple of weeks when its cooler and I give it a good strong launch I will definately get better times. I just emailed Rich about the j-pipe and test pipe. I know people have been seeing great power gains with these. Need something to cool that air down. Intercooler is just a pain to do though.

Im gonna ask again, is there large gains to be seen from a modded cold air vs the ct airbox? It seems to be ok, but i second guess its design.

 

working on your reaction time and running slicks on the front are a couple of things you can do as well to improve...

 

thats actually not bad considering you have no tune and still running the stock jpipe and primary cats. next time you go, bring some ice packs and cool it down between runs for at least 30 min or so. it makes a huge difference for your trap speed. i trap at 107 consistantly, but if i go back to back runs my trap falls to around 105mph

BTW, what were your 60ft times?? people dont realize that is the key to getting a good ET. trap speed means squat, if you cant hook up... get some DR's and heat them up until you feel them grab (6-8 sec) and launch at around 3000-3500 rpm. if you can get your 60ft down to 2.0, that same run will yield a 13.3-13.4 easily.

as for the CAI, i dont really think it gives much more hp IMHO. its the noise people feel the most, which does make it feel faster. i recommend it alone for the noise

heres a couple of vids of my car at the track late last year. i posted these up recently on the other forum. it shows you the launching technics i use when i race and the beautiful sound of the CAI

me against a 04 mustang cobra,



me against an evo

 

wtf was the guy in the evo doing...excellent kill

 

The mag numbers are definitely real: 14.2-14.5 stock for the base 6MT. One member here ran 13.9 in an '05 6MT with just a CAI and there have been several running 14.00's with light bolt ons. Hec, OMP Prelude ran 13.7@101.xx N/A, with basic bolt ons.

Weather, altitude, driver skill and track conditions all play a huge role in times and trap speeds. I think with a little more practice at the same track, full exhaust bolt ons, drag radials and cooler weather, you'll be able to bag some 13.1-13.3 slips.

 

Ho much of a difference alone will these make

 

with the blower i ran a 13.7@ 107 spinning badly through second on street tires...all motor i ran a 13.9@101 on the same street tires lol

radials or slicks will be run on next time

 

someone correct me if im wrong but reaction time is not included in your times. it only helps you if your racing to the finish line.

 

first off

sean, 04accrdcpe... nice pulls man.. i love your ride... and envy your power

to the OP... a j-pipe will DEFINITELY make a huge difference in your power/times IMHO.. on a f/i TL, i would expect 15+ whp... i gained 12whp on a N/A Type S 5AT.. also, pre-cat deletes.. should be worth another 15+whp.... 30whp, would probably = about .30 off your 1/4 mile

 

04accrdcpe- My 60 ft time was 2.26. and that accord is a bad mf.

 

whats the best way to get a hold of one of these jshift j-pipes?
I sent rich an email but still have no reply. Id like to do the install while its still warm out, especially if people are seeing this much gain of of it, itd be dumb not to install one.

 

You've got another .5 second locked up in that 60'. Get a set of drag radials or slicks.

 

Easy 12 second car with traction.

 

i know lol. fell asleep at the wheel i guess. that thing was pretty quick though. he trapped at 105mph.




ahhh thank u thank u guys... appreciate it


as for the jpipe and precat deletes, it works the opposite believe it or not. you will gain more whp off these mods N/A, than if your S/C'd. your already force feeding the engine, so its flowing alot more effeciently than taking air in on its own. i gained practically nothing installing a jpipe and hollowing my cats, but i did gain a few wtq though.

im just saying this now, so you wont be dissapointed like i was, after spending the money on these mods, only to feel minimal gains.

i remember back when the procats came out, the NA guys were gaining anywhere from 18-21whp, while the SC'd guys only gained around 6-8whp. you wont gain as much opening up the exhaust on a supercharged car, than say if you were turbo.

 

weight reduction is one of the best modifications you can do. On the TL it is estimated for every 100 pounds you reduce weight, you improve your 1/4 mile time by .1 second.

 

sooo...taking out small shit like floor mats and ect, really wont do shit..lol

i mean..even the rear seats dont weigh 100lbs...
youd have to take out alot of shit to make 100lbs

 

we can only hope

 

every little bit helps.... take out the back seats and floor mats and spare tire and your bound to run faster times

 

^ Agreed.

 

op- nice runs man, I love the drag strip and wish I could have got my TL there but I never got the chance. I pull 13.4's in my x so your 13.8's not bad, keep in mind people that the s/c is only giving a small amount of boost, the hardest part is controlling the launch and your nerves lol

 

but like what? .1 and . 2sec faster..wow....
not worth all that work for a millisecond..lol

 

do you power shift? i know that helps a lot.

 

whats power shifting???

 

I told him to powershift that bitch before...

 

if you have a manual transmission.. just floor the gas pedal and dont take your foot off.. even while stepping on the clutch to shift.. it will keep the revs up... makes a difference.. hope it makes sense what i said..

 

^ alot of dragsters do it.

Improves alot of track times.

Many swear that it Destroys your tranny and engine...

But If done right, it will still not.

Discuss.

 

i guess you havent seen Inaccurate "putting tl on a diet" thread very good maybe you should read it....less weight= faster car kinda a no brainerlol

 

Every bit counts....if you're all performance.

 

Power shift works beautifully if you have fixed tranny thats design to do that...like what most professional Dragsters have. Think about it. They have LSD, shorter gears, different construction of the gears...and other things dragsters do to beef up their tranny.

...but with stock tranny like most of us have. Better buy a spare tranny if you like to do it often. Since they are not design to be power shifted, especially when you have something force fed.

I mean you can do it, but its up to you and your tranny, if you know what i mean.

 

^ Like I said, if done properly, it won't kill the tranny like everyone expects it too.

Just as bad as when people street race or launch cars or hit redline like all the time...doesn't make a difference.

 

off topic, sorry...

but does your friend own a TSX as well? If so, i think he was the one who called me with his headlights sealing problem. I lost his number....never got back to him.

if not, nevermind....

 

Any normal transmission is not designed for it. If you manage to co-ordinate the clutch and shifting perfectly, your clutch will still hate you as will many drivetrain parts.

Transmissions such as Lencos are a planetary style trans using clutch packs much like an automatic but with a clutch in place of the torque convertor and a shifter in place of hydraulics. Planetary gears are always in mesh, no actual shifting occurs, only applying different clutches for different gears. Completely different than anything ever installed in a passenger car.

 

yup...his name is ben..
