pwned by traction - Honda Prelude Forum

NtPReLuDe · 05-07-2004, 01:18 PM

Well I went out a to the track a few weeks back and ran a 13.599@110.94mph with a 2.439 60' I thought if I were to improve my 60' I would be able to drop into low 13 territory. So last night was sport compact night at the local track, which means a lot less cars and more runs. Anyways, I here were a few of my runs
60'-----2.270------2.252-----2.212-----2.228
1/4----13.674-----13.678---13.535---14.129
mph--108.63-----108.24----111.80--111.01
So my 60' got better but my times aren't improving, traction pwns me. I really wanted to try and break 12's on street tires but it doesn't look like it's happening. I can control the launch but right after it grips, it'll breal loose again. And I even have to shift slowly to second or spin right to 3rd. And thats not good cause I'd bog and the revs drop to 3.5k
I think I'mma try running a lower boost setting for 1st and second then the full 18psi to see if I can run better times, if not then I guess it's time for some DRs

It doesnt really make sence, your 60ft times improved, your trap speed was about the same, but your time were slower. How is traction after your 60ft mark? Maybe your easing into it to get good 60ft times, but then breaking loose after that? Good times by way.

i agree with ^^^, it doesnt make sense. the only thing i can think of is compared to before, you're loosing your traction in higher gears.

IIRC, you use the EMS? try boost/gear settings.

Out of curiousity, what size tires are you running? Do you have a LSD?

I'm also hoping clendaniel can chime in here, as we know his car is in about the same ballpark as yours, as far as power levels go, and isnt he in the high 12s?

No lsd, 205/50/16 yoko es100 @16psi... I started at 20psi and lowered it till I got a decent amount of traction in 2nd. I wonder if 225/50/16's will work better then 215/50/16 on the stock rims.... I actually swapped out the aem ems to hondata. The only thing I can do is get the greddy remote switch and launch at a lower setting, run thru 2nd and switch to high in 3rd.
I think clendamiel is well into 12's with slicks. I really want to break into 12's with street tires before I run slicks. I would also want to get a new set of axels with them, which means even more $$$.....

try the LSD
running open diff on a high hp turbo car is a

and you know it

that should help a bit...oh and drag radials

nuro · 05-08-2004, 06:55 AM

lsd = twice the rubber.

why'd you change ECUs?

heh...yeah, I've only gone 12's while on slicks. I ran a couple times on street tires and was only able to manage similar times. I'd be _really_ impressed if you can break into the 12's on street tires...not that it's impossible but it's gonna require some great driving and most likely gear dependant boost control.

and are you running an LSD, ian?

Tony · 05-17-2004, 01:36 PM

I don't think the LSD is your main issue here. There is a guy here w/ a prelude Type SH w/ AEM EMS and his atts still on the car running 11.9s on a daily driven lude. His runs were all on slicks.

NtPReLuDe · 05-17-2004, 10:06 PM

you saying he has the aem ems and still retains the use of the atts?

Tony · 05-18-2004, 11:13 AM

yes. I don't think he would lie to me and the light certainly was not on in his car.

Yup, quaife in a h23 trans. Not to doubt the person that claims to have ATTS w/ an AEM but even if you did get it working I doubt the ATTS unit would withstand the power necessary to propel a full-weight 5th gen to an 11.9x. It would only be a matter of time before the clutch packs are worn out. Just because there is no light does _not_ mean it's functioning...before I removed mine and converted to a base-type tranny I had pulled the ATTS ecu and had no light. If he does indeed have it functioning I'd urge him to post the details over at the AEM forum as there are alot of individuals that would be _very_ grateful.

Now that you say the light would be off, makes me wonder if his unit is working. I wonder if there is a way to verify it for sure.

Come on buddy you should know on a high hp turbo'd car, traction is your enemy. Dont bother with Drag Radials just get some full blown slicks. Some nice 26inchers! That should get you easily in the 12s baby Yea!
