Can't get traction!!

JWT_sr20 · 09-10-2007, 01:53 PM

Hi!! I hope you can help a SR20 friend.... we have a problem with my friends car, it's a B13 4 door sentra with GTi-R engine swap, FMIC, 3" downpipe and exhaust, haltech e6x stand alone...... the problem is that at 0.9 bar the car can't get any traction, his dyno numbers at that psi were 269hp....after that he wants more power, so he bought a walbro 255 and when he tune again the car with 15psi the traction problem grows..... we know in USA there are a lot of b13's with that amount of power and we would like to know how the F***K to make the car to get traction....we need full traction un 1/4 mille....any comments are accepted, please help!!!!

Thx.

Get a drag radial tire for the street... or a slick for the track, and "warm it up chris".

if you're having traction issues at aroun 269whp your def going to get it with higher boost. On the street forget about it.

Even with a t25 you'll have traction issues w/ boost in the double digits.

The car actually have a custom made suspension, that suspension it's almost the same that my car's suspension, i have orange koni and eibach springs.....the suspension its hard......
Also the car is with race motor mounts, very strong!!
We are going to use drag radials for the 1/4 mile race, but that can brake the OEM ball joints?? any suggest?? traction bars? any bars? what ball joints?? lsd??

Here are some posts of tracton bars.... I have seen the Hass ones work and very well. See if you can get some ideas for your own... as Hass is now out of biz and I don't know anyone else that sells them. I will be building a few sets for myself in the very near future.

Traction bars wont do squat if your running crap tires. Good tires + traction bars = less wheel spin

I agree100%.... you have to have good front end parts..good tires... good suspension... and traction bars....less wheel spin... another big factor is alignment with the camber settings... if you can get a more surface area of the tire on the ground that will also reduce tire spin.

MOOG ball joints are very nice. I haven't heard of anyone having ball joint problems because they have a high power car, just normal wear and tear.

www.rockauto.com has a full selection of MOOG parts. There is also a discount code in this thread (good through 10/02/07):
