Based on what facts?

Plenty of people using the ULT with no issues.
The price difference is over $800.

 

Please tell us why.

UD.

 

You're being ridiculous. There is already a Greddy kit making 330. To be fair, you have to look at stock boost vs. stock boost. Greddy makes around 285, and Comptech makes near 300. The Greddy will annihilate the Comptech.

Sure, if you're pushing 10-14 psi on the Comptech you'll be faster, but that's a dumb comparison since the Greddy kit can't boost that high.

Turbo > Supercharger.

 

That pretty much sums it up

 

Im looking to go FI soon to but the problem is i dont know which one is going to be more reliable...

I kno turbo will be better for 1/4 mile etc.... i just dont know if it would be able to stay cool with driving at about 100-120 for extended periods of time.

 

So wait, the greddy kit makes less power stock, and has less overall potential, but it is still better than the Comptech kit? Interesting how that works.

 

oh boy

Peak power is not even HALF the story



As far as potential, a greddy kit can hit 330ish and a comptech can hit about 360ish, for all intensive purposes thats the same. I won't even start on torque as boy-racers don't understand power under the curve / what torque means to hp.

 

There are 2 or 3 guys into the 400's using Comptech kits and more are running between 360 and 390whp...I think there are 5 or more guys making over 400whp with the Vortech SC...FYI

Any SC kit and any turbo kit has more potential than the little Greddy snail. Let's not even talk real durability tests like track days...

 

Oh you wanna drive around at those speeds for extended periods of time? Oh, you mean like you do when you're tracking your car? Well, there's shitloads of SC guys who don't hesitate to go beat on their cars and numerous full-blown SC'd race cars. MSM_S2k built the first and only turbo race car but I am not sure what happened to him. I have not heard the whole story about that.

Turbo's are great for driving on the street but, for whatever reason, I see hesitation from turbo guys looking to track the car (probably due to being in boost for extended periods of time and generating a lot of heat). You will hear guys constantly saying that turbos are better than superchargers...and they are. There's no question about it. But, us SC guys always get to pull the proven reliability card. There are even a few guys running 14psi plus on stock HG's with the supercharger without issue (so far). How? Because SC guys hit peak boost for far smaller durations than turbo guys who make peak boost at 3500-4000rpm, and sustain those boost levels to redline, thus generating a lot more heat. This difference also accounts for the performance difference between the two. On top of this, turbos run off exhaust gases whereas superchargers require the engine to rotate the compressor wheel (leaching hp). So, ultimately you get great torque/hp out of the turbo setup along with more heat.

Some will try to convince you that SC's are crappy, etc. I contend that, if you want track reliability, no one has PROVEN that you can consistently track a stock motor S2000 reliably using a turbo setup. You should go the SC route if you intend to do HPDE's and that sort of thing. If you want a car that feels fun to drive, pulls like a freight train, and is street reliable, there are turbo setups that achieve those goals.
