Just wondering if any of u have read the new Sport Compact Car magazine?

I know about you guys but these fricken cars they they moded up go just as fast as the stock, if not SLOWERRRRRR. Yeah, u heard me! "SLOOOWWWWEERRRRR."

The supercharged S2000 by comptech does 0-60 in 5.7! I dont know about u, but some stock S2000's do it less than that and THIS S2000 has 50hp more! (maybe more...didnt read that carefully). Anyways, the slalom was also slower. About 4-5mph slower. In fact, the Neuspeed S2000, with its single mod (exhaust), had better slalom numbers than the heavily moded Comptech S2000.

They blamed the slow numbers to the car being lowered They say the back end gets alittle too whippy and lively during sharp/quick transitions

Makes me not wanna buy all the stuff i just ordered

Anyways, Im hoping someone will tell me all of this is wrong and those numbers arent right.

PS, i think import tuner has a few dyno tests on the filter, exhaust, and header....and let me tell u, those numbers just SUCK! Why spend that money on fricken 5 hp total? I dont know....i feel like im getting ripped off now.

 

The tester for the magazine was having problems with wheel spin. That's why the acceleration numbers are so low. The car just doesn't do well doing a drag race type launch. The S2k is not the easiest car to drive at the limits, plus they used different testers for the two tests.

They did their own dyno testing and stated the horsepower and torque gains that they measured. With that much extra power, how could the car not be faster if it wasn't for traction problems?

 

I`m sc`d and it MUCH faster. Comptech engineered a great kit. You could install it w/ your eyes closed!

 

Mike,

What kinda numbers are u getting then for each of the parts dyno'd then? And what numbers are u getting 0-60, etc etc.....particularly the slalom. The Slalom numbers were told to be due to the car being lowered. You cant blame that on the car having too much power because the Nuespeed S2000 has only an exhaust as a mod and it had faster slalom times than the Comptech S2000's.

Anyways, basically what your saying is off the line, a stock S2000 should be able to better or equal your Comptech S2000 and also during the slalom or quick transitions on the track?

 

We've only done dyno testing on the car, but no 0-60 or slalom runs.

Apparently the S2k bumpsteers real bad, like most Honda products, and we are looking to see what it would take to fix it. The Neuspeed car had a set of prototype Koni shocks on it, while our car had stock shocks. That can account for some of the difference in slalom times because the car will react differently to steering input. Also, the two cars were tested on different days by different drivers, and some drivers can get more from a car than others.

 

s2oooboy,

I believe the Comptech S2000 is loosing alot of time with those 18x9's and 265/35/18's in the rear.

1. The 265's are a bit wider than our 225/40/16's but I don't know if they are more sticky.

2. The 18x9's with the 265/30/18's are heavier than the stock setup.

3. Also, 18's are horrible to drag race with. 16's will have a bigger vertical contact patch.

I bet they will get better 1/4 mile times with the stock wheels and tires.

 

s2oooboy,

Yeah...the BF Goodrich TA KD 265/35/18 are .3 inches wider in tread width compared to stock 225/50/16 S02's...but...

1. They are not as sticky. S02's have a UTG of 140 and the KD's have a UTG of 200. UTG is tread wear, and the lower the number, the quicker they will wear out. This is not generally a good way to find out which tires have better grip on dry land...but it is a good estimate...and it works for generalizing the stickyness of most tires.

2. The 265/35/18's have a 25.3 inch diameter. Stock s02's have a 24.8 inch overall diameter. FYI, in most applications, increasing the stock diameter of a tire will decrease low end acceleration.

3. If you look at the KD's tread pattern, you can estimate that our S02's have a bigger contact patch.

So...

I figure that the Comptech wheel and tire setup...

1. is not as sticky as stock.
2. has a bigger overall diameter.
3. has a smaller contact patch.
4. is heavier.

Take these attributes and you will loose some time compared to running a s2000 with stock tires. I have raced a stock s2000 with my 245/35/18 Toyo tires...and loose by at least a car length every time at the launch...and my 18 inch wheel/tire setup is 4 lb. lighter than stock (each wheel + tire). When I switched back to stock tire/wheel setup...I gained my lost car length and some...

 

Ok, ive calm down since my last couple of posts

I just got a few questions for u though, Phantom (and anyone else who knows about this). I know your car has Volk TE-37 18's and say you lose a car length at the launch? Does that mean u make it back up later on?

Also, why did u decide to go with 18's then if u knew it was gonna be slower? Do u notice that u have better cornering stablility and ability with your 18's?

I knew from before that the bigger the wheels, the slower your 0-60 and 1/4mile times. But I also know what u lose in straight line times, u gain in cornering ablity, or at least thats what I heard. In fact, this whole decision on what wheel size to go with was in another SCC issue which did 0-60, 1/4mile, and track times. To make a long story short, the results revealed that going with 17 inch wheels (stock 16) provided the quickest track times and similar 0-60 and 1/4mile times. AND, it proved to be the quickest of the three sizes that were tested on the track. They tested 16, 17, and 18inch wheel sizes. Anyways, thats why I decided to go with 17 inch wheels with SO-2's.

Now, going by what u said about contact patches and Stickyness, and wheel and tire sizes.....shouldnt my car still do similar or equal to 0-60, 1/4mile, and have quicker track times?
