Preparation for the STILLEN supercharger

travisjb

Congratulations, fantastic result! Looking forward to z version and official release...

So, I think you're 6 car lengths ahead... too soon to declare you the winners of this race?

I think both GTM and Stillens supercharger kits will both put down impressive yet comparable hp/tq numbers. My guess would be price will sway more people than the hp/tq numbers.

RCZ

I disagree. I think there is SO much more value in the Stillen kit considering the amount of testing and engineering that is currently going into this kit. If you are going to pay 5k+ for an SC, you aren't only considering price and hp figures. I have seen a lot of things that, to me, are worth much more than whatever dollar difference there is and that is even before we talk about the HP figures. Think about the fact that there is a water cooled intercooler inside the custom designed intake manifold. I'm not sure exactly where the comment about the "other" kit having more engineering going into it than the stillen one came from the other night....but I honestly fail to see how that is possible. I'm sure they will keep it competitive anyway.

I think when people are spending this much of their hard earned money they naturally tend to weigh many more aspects of the buying decision than they would for something cheaper. Price is never the #1 reason.

I'm going to agree with Travis and say this race is over.

I would really like to know how these sc'ers do with the 7at tranny.

I also think the water to air vs air to air is way better for intake air temps. I am really suprised that GTM is not using some type of water meth injection with their kits.

Nice job Stillen !!!

I hope the price is reasonable..... I do expect it to be more than the GTM kit...by about 20 percent...

Red370

I agree completely, Reliability will be the number 1 factor for me, Power comes second, I want to know that I can install a kit and drive worry free for the life of it, or at least for most of it.

While comparing Dyno printouts from GTM and Stillen I noticed that the GTM sc had a million parts. On these systems under stress anyone of which could be a point of failure. Although I haven't seen the Stillen sc laid out, from what I can tell it's far less complex as to the number of components. For a DD that for me would be a plus for Stillen

I hate to ruin the mood, but the only thing bothering me about this kit is the torque graph. Everything else looks great though.

The torque curve is pretty consistent with the type of supercharger they are using. Boost builds as the RPM's come up, which is why the torque peak is now nearly 7000 rpm.

MMC Racing

Until these kits end up on customer cars and are subjected to various climate differences, we won't know who made the right choice on intercooler design. "More" engineering doesn't mean better engineering. In fact, keep-it-simple-stupid can be a selling point in itself.

There is no victor here. Both kits, when tested by themselves, performed well. I'm going to hold back from the temptation to save a few hundred on the presales and wait to see real customer results before making up my mind.

Anyone calling a victor at this point on either side is an obvious

RCZ

quick question Kyle, some of us rev to 8150rpm right now. Not that its a big deal, but I assume the tuning map for the kit is only responsible for 7500rpm?


MMC Racing - Stillen is doing extensive road conditions and track testing that simulate real world conditions. Also just because you say that makes someone a doesn't make it so.

Buddy Revell

I disagree with using the number of parts in a kit to judge reliability. It's far better to look at a company's track record and reputation for quality in their products, IMO.

Nice #'s
I have a 370 Sport 7 AT, my base line is 265 SAE rwhp. Your dyno reads HP. Is it standard HP ?
How can a Stock G make 289 ? With all the stillen bolt ons I made 292. You made 133 rwhp. on your SC. So that would put my car at aprox 398. I would like to see your RWHP converted to SAE RWHP. There is a difference between the two. It appears that your dyno reads a little on the high side.
I have your SC on my 350 z and i never got near your posted #'s And my SC was also ported with a custom stillen stage 4 tune in it.
