When it comes to handling and turns the car is like a walk in the park and feels at home which it is, thats what it is built for. Take it to the 1/4 mile and its just all kinds of fail. So my best time over a year ago was 15.4 @ 92MPH and like a 2.5 60'. Terrible and embarassing but I had a short ram getting crazy heat soak, heavy wheels, a huge exhaust leak at the header and some audio stuff in the trunk . Now I have lighter wheels, better tires, a proper intake and exhaust and nothing in the trunk. What do I run? 15.5 @ 89 with a 2.4 60'. Now how the hell does that make sense. Why are my trap speeds so much lower now. What in the world am I doing wrong? I know my clutch is slipping. On the street the car rips cause the tires slip but on the track the clutch slips and its slow as ****. But whats with the 3MPH trap speed difference and why are most running 14's atleast yet I cant even get a 14.9? Help me lol

 

92mph means you're either heavy, have a slipping clutch or are down on power

you have the slipping clutch which you better fix before you race again

with a cool engine a good drive a stock itr can rip a 14.7-14.8 @95-96mph

make sure you race on fresh oil, cool the car down, do a tune up, change the fuel filter and practice perfect shifting at redline.

do this and provided you have at least 180psi of compression and you'll nail high 14s with no trouble

 

I've never raced my R but I do know when I raced my Z for a RWD car a 2.5sec 60ft is way too slow. Is the FWD Type R supposed to get 2.5 60ft times stock? If not then I'd say you need to work on the launch. If your car has healthy compression and you're not hitting more MPH then yes it's either heavy or you need to shift better.

 

An R can hit 2.0 60ft if you do it right. Its all about tire and experiance.

 

Well, sir, the problem is right here....

 

Back when my R had just bolt-ons (i/h/e) I believe my best time was a 14.3 @ 96. Although I did let some pressure out of the front tires for a bit more grip.

 

I wanted to experiment with tire pressures and things like open airbox vs closed but the clutch situation was bringing my spirits down. Now I know with slicks you don't run a lot of PSI but with street tires I always heard maximum grip is at the recommended PSI. I had 35 PSI up front and 42 PSI in the rear for better rolling resistance. For my suspension I set the Koni in the rear to full hard/fast rebound figuring on the launch it would weight transfer quickly to the front again. My shifts can't get any faster but my 60ft needs to go down. I'm going to compression test it just to make sure everything is good but with a 2 hour drive at 5000rpm and 5 track passes I didn't burn a drop of oil.

 

for dragging an R like a ricer

And uh yea, clutch slip may be the root of your problem. Fix that, and if that doesn't work, then

 

Trying to find a clutch is killing me. I researched a bit on comptetition clutches and a lot of people have had problems. I checked out clutchmasters but their stage 3 says not recomended for road racing. WTF is up with that? If the stock clutch can do it why cant this? Then theres Exedy and ACT. Stock replacement clutches are not going to hold up to abuse very well and a race clutch that is on off is out of the question for street driving. Ive driven a car with a carbon twin disc and the car no matter what is so jerky when trying to drive normal its just dumb.

 

well the car is obviously NA based on your times. get an exedy stage 1 and be done with it. they drive like stock and are much more resistant to abuse. their stage 2 also drives fairly tame for what it is and can handle slicks, road racing or mild/moderate turbo setups.

also a 2.5 60ft is normal for standard street tires. FWD is a different world than AWD or RWD

 

Will a stage 1 exedy be sufficient for a fully built 2L all motor or a supercharger? Either or is the route I'm taking.

 

uhh your the ricer here for fronting like you own an r.

 

Probably pushing the limits of the stage one with that.

 

Thats what I was thinking. Plus cerametallic clutches grip amazing which is why I think I have decided on the stage 2. Exedy stage 2 clutch and 9.5lb flywheel. Should be a nice increase in acceleraton not only from something actually gripping but the lighter flywheel. Im a little nervous on what that setup will be like on the street as far as like a daily driver.

 

5K RPM'S? At 70 MPH (I'm guessing) that wouldn't be a stock final drive right?

 

if that's you're down the road plan get the exedy 2 package. it will handle moderate turbos. superchargers and aggressive driving. it's rated at something like 285ft/lb and it's fairly easy to drive on the street. not nearly as grabby as a solid 6 puc disc. it's a little faster to engage than the stage one but still quite streetable

 

practice practice practice

get the launch down, launch at like 5k feather the clutch, ride it out in dont shift into second to early, lots of people see it spinning and will shift to second an the rpms die, cuz you shifted to early

do it right and you can run good times

in my 2001 itr, all stock except for a aem cold air, stock interior, still had back seats, stock itr wheels, falken azenis, i ran a 14.2 at 98.9 mph 2.0 60ft, to run good times in drag you gotta drive it like you stole it, you cant be nice to it at all

 

SLOW!

 

Get one of those GTech things and spend some time in a backroad practicing diferent launch methods. You're looking for some wheelspin and when you catch traction, you probably want to be at 5-6k rpm in order to prevent bogging.

That's after the new clutch of course. Right now, it's not possible to say if your crappy short times are due to your launching or your slipping clutch.

 

01 i/h/e i ran 14.6@97 mph

 

It's the JDM 98+ trans with the 4.785 final going even slower than the flow of traffic. Speed limit is 70mph and the left lane is doing 90-100mph and the right lane is going between 80-90mph. I stayed in the slow lane a bit sometimes even going the speed limit when there's a break in traffic just to give the car a break lol.

 

OK I'm going to jack and twist the thread here a bit. When you're at the top end of the strip, do you keep the car in 4th gear or are you shifting into 5th before crossing the line? This is something I've wondered with the JDM f/d and the 4.92. Sorry to get the thread off topic.

 

Remember the JDM trans with the 4.7 final uses a GSR 4th and 5th gear. This makes it accelerate faster 1st - 3rd and 4th its longer and evens out with the USDM 4th both run the exact same time

 

As soon as you said this I remember seeing a vid on that. Thanks for reminding.
I believe it's the USDM tranny with the 4.92 that requires 5th gear in the 1320.

 

Wrong car. Obtain a turbo **** box and reattempt.
