So how does one go faster cheaper? Effin' diet for you and your car!!!


And Hoosiers.
This is not going to work for me. I've been picking up all the weights everybody is loosing.

The PTuning kit should help you take care of that.

Nice, how did you do?


We are running the Chump car race at VIR at the end of the month, will you be there?
The car was not finished all the way by the time we got to the track so we spend the whole day on saturday fixing her up. We got the car running with the new paint job for sunday. Little 1.8 turbo that we stuffed in there was crazy quick in comparison to the old engine! The car is now seriously competetive in B class .

I almost shed a tear that sunday when I saw our car fly through the straight passing left and right while making wonderfull Pfhhhh!!! turbo sounds! Just the thought that everything in the car was held together by JB, gourilla tape, and zipties while watching it go fast made me a bit sentimental I mean, the compressor outlet and one of the engine mounts was essentially JB mixed with aluminum piping. Just the fact that that was not the weakest link was shocking on its own.

So the car ran for about 2-3 hours on sunday untill we lost all the water due to the leak from the back of the engine (still need to diagnose it). The car came in the pits red hot with no water in the cooling system AT ALL! Surprizingly, the engine still ran and had power. So we just waited till the last 5 min of the race and send it back out to finish the race. All the water was gone in a matter of 2 min, but again, the engine held up and we finished the race.....in the second to last place So besides that loosing water issue (and also shooting the exhaust off due to backfire...and bad bearing....and some other stuff) everything was dandy!

At this point the plan is to assess the car's condition and to deside on either fixing it or building another car.....
If there is anyone on here that would be interested in taking part of renting a big warehouse space to store and work on cars please let me know. We are trying to reach that "critical mass" of people to make the idea feasable.

Highway driving on a moderate speed of 75 or higher on heavy downpour is no problem at all, traction is very confident with a good thread of course. Most tires are rated 55MPH to start hydroplaning.

Full tread Starspecs are very good in the rain. Once they are more than 30% worn their performance drops off sharply.

Question: If you have a separate set of rain tires/wheels, is it a good idea to run the 255 width? Or would it be more beneficial to run a 245 or even a 225 on an 8" wheel? From what I have heard, the wider tire can increase the risk of hydroplaning, so does that play a part?
I think some folks are getting overly hung up on adding 10mm tread width. I'm of the opinion that running a 255 on an S2000 is only really warranted when it better fits the wheel itself. A properly fitted 245 will outperform a 255 tire on a not-properly matched wheel size. I know thats not a "wet question" answer, but +10mm marked on a sidewall doesn't mean "better." Sidewall deflection and the ability to maintain optimum contact patch are big considerations.

Now, a tire can only evacute so much water. If the amount of water trapped under the tire exceeds this, hydroplane happens. So to correctly answer your question, the actual tire in question must be considered. All things being equal, wider is definitely not better in standing or streaming water. Also remember that alignment and suspension setup play a huge factor in wet traction. Soften shocks. Up tire pressures. Must of us won't change an alignment at the track, 9kI4 (Matt) excluded , but that would be optimum.

Another consideration for some of you- if you have aspirations of TT'ing or racing down the road, look at the rules and/or point assessments. Running a 255 makes no sense from a point standpoint in TT's when the benefit in time is nearly immeasurable. Use the point(s) elsewhere, like weight reduction. Racing spec's the size.

Wanna go fast? Weight reduction. Everywhere. Wheels (rotating mass). Battery (up high and in front). Etc.

And Hoosiers.
I guess I was just saying since most people are running a 255/40/17 tire..when you guys are recounting your experiences driving in the rain were on Hoosier Wets was the width the same or narrower tires on narrower wheels?

I need some ideas on reducing weight. Not to myself, if I did, I would disappear if I turned sideways, I mean to my car. I removed a lot of the interior and stock bulkhead but added a heavy duty rollbar that negated weight savings. I swapped the radiator out for a very lightweight aluminum one, but since the capacity is so much more I added back a lot of water weight.

The idea is to have in within 40 min of driving for all of the participants... Gaithersburg airpark, Columbia, 200 ICC triangle.

A Hoosier Wet 245 is wider than a street tire 255 when stacked 4 high.

Why the aftermarket radiator?
