So tonight I went to the track for the 2nd time on my slicks, and again the car does no burnout to heat the slick. Let me get you caught up...

I picked up a set of 24.5x9 Hoosiers and some Lenso's for my turbo Integra. Take the car to the track 2 weeks ago to get some time in on the slicks. I had the car on 6lbs of boost, 2step set at 5500 the first 2 passes and 8-10 psi in the tires. Pull up in the water box, rev to 2step, release clutch, yank ebrake and car just sits there revving, will not spin the tires. So I think, hmm maybe it doesn't have enough rpm's to spin the wheels, so I raised 2step to 7k and same results. I tried pulling the ebrak before dumping the clutch, tried dumping the clutch then pulling the ebrake...nothing. Only good thing from that night was how the car ran, it went 13.1@109mph 1.9 60ft


Tonight the track opened back up (closed last week for repairs), so I decide to go back. This time I am on 10lbs of boost and thinking, yup I will be in the 12s, wrong! Start off with 8lbs of pressure in the slicks and 2step at 7k, pull up in water box and it starts to do a little burnout and then it just kinda stops and doesn't really do anything but start rolling. Went 14.8 due to a 2nd to 5th gear shift, whoops!

Next pass I again pull up in the water box, try getting the slicks hot and again nothing, this time I didn't miss any shifts but yet I ran a 13.4@107mph with a 2.2 60ft....so in the matter of a week I lost 3 tenths and 2mph, and the only thing different was raising the boost 4psi.

The car setup is:
Benson 84mm GSR Fully built
GSR trans w/Mfactory LSD
Precision 6262 Ported S
10lbs of boost
24.5x9x13 Hoosier slicks
Tuned on Hondata

WTF am I doing wrong as far as the burnouts go, and why is this car not in the 12s where it should be...please leave smartass comments out, trying to get this figured out without having to deal with the bullshit posters. Help is appriciated

 

are you building any boost on the 2step/antilag?

and what gear are you doing burnouts?

 

You might be best to post a video, a log and your calibration for the best results.

Really impossible to tell you what might be going on without knowing more details.

 

Yeah I figured that was going to be the most common reply. I don't have any vids unfortunately and couldn't log due to the tech guys at the track being ******** cause I don't have my laptop mounted. They were in ***** mood tonight becasue I have seen others with laptops unmounted in their cars in weeks past. I might go back next week and see what the hell the deal is, but 2 weeks in a row and unable to heat the tires up. I am almost wondering if the slicks are too big for my current setup? Judging by what others are making with very similar setups I should be right around 375ish whp...but until it gets on a dyno thats just butt dyno calculations

Also I have tried both 1st and 2nd gear during the burnouts

 

If you have the S300, you can easily setup ON BOARD LOGGING.

Check out the help file in the SManager software as it will be helpful.

 

Alright I will check that out.

 

What clutch?

 

Same question here. Potential clutch slippage since OP mentioned the car sits there and rev's without tires spinning. Surely the slicks aren't too large, I ran 24.5's on my car with 217whp and was able to do 2nd gear burnouts without an issue.

 

^^^ This. ^^^

What brand & type clutch, how long has it been in the car and was it broken in properly?

 

Comp Stage 5 w/extreme PP, it does not slip, I have vids of the car on the highway and it defintley bites nicely in every gear no matter the rpm. I know what a slipping clutch is as my old crx's clutch blew chucks off the pucks and would just free rev with out going anywhere, this is totally different. Its not like the car sits and just revs to the moon, its almost as if its hitting a wall when I rev it, hard to explain I guess. Vids will help hopefully

Clutch had 500 miles of break in, with easy driving i.e no burnouts, launches, hard shifts. Clutch has 1750 miles on it currently along with the entire setup in the car. So I am gonna rule clutch out as being the issue.

I will datalog and get vids next time for sure. My buddy who was behind me in his car said the car started to do a burnout, the wheels were spinning and then it was like the car grabbed traction and just kinda pulled the car forward. It will do a rolling burnout, but there just isn't enough room at the track to get the slicks heated by doing that method.

 

IDK man, this sounds alot like the clutch is slipping to me...
Where else could the power be "lost"?
If its not bogging down, and the wheels are not spinning, the clutch has to be slipping.

 

Maybe youre not building boost on 2 step? Judging by your 60', Im gonna guess so. Does it bog off of the line, or spin em off of the line? Sit on 2 step longer, before you let the clutch out. Also, I used to pull the ebrake (now I dont, because it will gradually reach rev limit, rather than smacking 9500 and banging it there), hit 2 step, wait for it to build some boost, start to feather the clutch (which will apply more load and build more boost), and then dump it. Kinda like preloading, but preloading too much to where it pulls/spins the tires.

 

I bet the tune is off at the load you are trying to launch at.

 

If u release the clutch pedal and the car is revving and not spinning the tires, the clutch is slipping. There is really nothing else that can be going on

 

don't need to datalog to know when the clutch is slipping lol..... clearly its the clutch.... car is in gear, engine revs, wheels don't spin............ you say its a comp stage 5? no way it should slip, but it looks like you got a bad pressure plate...GL

 

maybe the tire are spinning and you just dont realize it

 

Trust me it is not the clutch, the car runs and drives just fine down the track and on the street. I said eariler that the car doesn't free rev like a slipping clutch does, it revs normally but acts like its hitting a wall (almost feels like the ebrake is holding the car back). The car does rolling burnouts fine and will blow street tires up, just won't spin the slicks.

I think the idealone is on to something, I do not believe its building enough boost during 2step as it does bog a little bit off the line. I might take the car out to a close location this evening, toss the slicks on and do some burnouts with a video camera handy lol.

Heres a vid of it on 6psi going 13.1, doesn't look/sound like a slipping clutch to me at all....

(pay no mind to my overly excited wife lol)

maybe your not revving high enough on 2step, or try run higher psi in the slicks

 

if you are in the box (wet tires) and you hit 7500 rpms, and you are set to build 8psi and you release the cluth and the car doesnt die but just sits still and rev's your clutch is most deffinately the issue man or your popping out of gear when you release the clutch pedal.

also set the ebrake before you start to rev then dont just drop the clutch either but let out of it untill you fele it start to pull then release.

slicks and street tires are not even close to being the same animal man one grabs the other spins this is why we use water to turn slicks and heat them up.

one again if your car doesnt die when the clutch is fully released and it doesnt move then your clutch is an issue

 

Interested in the solution. If you are in gear, clutch pedal is released, the tires do not spin but engine revs shows it is more than likely your clutch. The only other option would have to be what Sanman just said; "your popping out of gear when you release the clutch pedal."

 

Just what i was going to say... if the car is still running and has not stalled (in the water box), its a clutch or popping outta gear

 

so you did a burnout till the tires were heated and dry so they pulled you forward but yet your car isnt burning out. hmmm thats a hard one to diagnose, im at a lost. stop thinking of burnouts with street tires

 

If it was a slipping clutch, wouldn't it do it other times besides just when doing a burnout....because the clutch definitley holds the power in every gear while being driven.


For arguments sake I will toss a video up asap in hopes of proving its not the clutch thats the culprit. That way 1 thing can be ruled out and maybe the answer will be revealed


This is not my car but reminds me of what my car has been doing on the slicks

is this still on a factory diff???

 

That car doesn't have lsd
