I've got crappy street tires. I'm at 375rwhp now and don't get **** for traction. However, lets say I do a 100 shot and slowly ramp up the power. Is there any hope for traction?

not at lower speeds....you would need to use a delay and ramp....just put a tire on it and call it a day:cool:

I'm right where you are power wise (380rwhp). For some reason I have no traction issues off a slow roll spraying in first gear...can't tell you why really. I run street tires and only weight in the trunk include the bottle and maybe 75lbs of stereo. However at the track, I spin like crazy in first and second with sometimes into third. Get some sticky DR's and call it a day.

nittos will hold at that level pretty decent. there are other choices that are better though.

DRs may be an issue here in rainy southern Louisiana. I was thinking I could feather the throttle and spray from a roll. 275 front, 315 rear combo, btw.

I ran a set of 315 Nittos for almost 12K miles they actually get pretty decent wet traction when they still have tread....but once they start to go bald watch out

Of your running a WOT switch then feathering the throttle will cut the juice....

What I mean is gradually throttling(is that even a word?) to WOT. If I just mash the throttle, I'll spin. but if I start from say 1/2 throttle and stomp it, I won't.

Buy some cheap wheels and put some MT street radials on them for the track. Great tire.

Progressive controller.

I was making @ 600 when everything was said and done on my last combo (no current dynos) and I could spray on the street.

Granted I never tried from a dead stop but from a slight roll as long as I could hook NA (380ish) I did not spin as the power came on.

-3500 on 10%
-4500 100%

One trip out to the track I was having throttle cable issues. I was launching NA. Only 89% throttle was showing on the datalogs. I was also getting an unusually low 1.7 - 1.9 60 ft times that day on street tires. Typicaly I would expect consistent 2.0 60 ft. times. I later fixed the cable and was showing 100% throttle and my 60 ft times went back up.

as long as I could hook NA

this is the key....if you aren't hooking on motor adding nitrous is going to make it worse.

Yes the progressive will bring the power in easier...but you will have to be able to hook NA first;)

Definetly try better tires and maybe a rpm window switch.

Nitto dr's are actually great for 400hp. I drive on them all the time. In rain they are fine unless you drive like a moron. When any tire is bald its going to be ****ty in the rain, duh. I had a set of nitto 555 dr's that were nearing losing the middle treadline, and I still drove them in the rain without issues, unless yer doing 65+ in standing water, which to me constitutes driving like a moron. I also put my car hard into an on ramp under wet conditions and it didnt break the rear free until 90mph when I hit the metal connector piece between the sections of the road in the middle of the apex, at which point i let off and got lucky and straightened out. Ive pushed these tires hard in dry and wet conditions and they really are great tires for a high HP daily driver. I wont drive on anything less, thats for sure. Whats the point of having 400 hp if all it does is burn tires and you get beat by a stock 350z because its wet out. Oh, one more thing, even in slightly wet conditions, if you smoke em b4 you run, theyre still better than street tires!
