Whos will cost less?

Zsteve

Assuming both the Stillen and GTM SC will be of good quality and performance, whos should cost less? The GTM didnt fab a new intake manifold or intercooler and is using tried and tested paths so I would think that is a savings there. The Stillen did fab new things and Im sure that will add to the cost. Also which will proably have the better low end TQ and better avg gains thru all the rpms? This not meant to be a bashing war Im just trying to get a good reliable SC at its cheapest price. And I am looking for gains thru all rpms and not just max gains as I will be a street driver only, maybe a trip or two to the 1/4 mile just for fun now that Im in TX and they have a couple here.

I think the prices will be equivalent or damn near it between the kits. Stillen cast a manifold Gtm cast the intake tube and modified the compressor housing on the blower. The Rotrex is a more expensive blower than the vortech, but stillen's tuning method an sensor placement will cost more. fuel system modifications we don't know about but they will probably be the same. Gtm has a lot more bracketry than stillen and moves around most of the front side of the motor.

Well I hope they offer a warrenty for the engine then as they are moving things.

I bet they will both come in between 6-7k. Neither company is known for being the value or low price leader. That is why I'm a little sad that Vortech did not produce a kit since they have a history of bang for the buck.

People will say you get what you pay for and that is true as long as a name has some intrinsic value. If quality is similar, then it comes down to cost versus performance. Personally, I'd give up 10hp if the kit was $1500 less one way or another. Peak performance is only one factor in my decision making. If price and quality is the same on both kits, then bring on the dyno graphs and real world driving impressions.

Hoping the group buy comes between $5-7, otherwise it could be a looong group buy

I would be willing to bet The Stillen setup will be about 1k to 1500 more than the GTM setup. Casting a pipe is no where near the amount of casting an Intake with a water/air intercooler inside of it. Brackets and pullies are cheap as well.

NYBladeZ

once the systems come out every company will come out with a pulley, I believe NST already has lighter OEM pullies that they say go well with SC's no way to verify that yet

Most companies do not offer engine warranties with bolt-on SCs and turbo kits. None that I know of offer them on non-CARB legal race kits that most here seem to be interested in.

Zsteve

Well the Army owes me some 5K or so for the stop loss they did on me, so Im waiting for the pricing. If I cant get the SC then It looks like some HFCs and a LSD and gear change are in the running.

Oh and oil cooler for the TX hot weather.

Only problem here is that Vortech kits are cheaper because they are usually more simple in design that either of the kits in question here. Both companies have gone to some pretty big extremes (in comparison to the previous vortech kits) to make a kit happen on this engine/chassis combo.

Right on Steve, wait til summer hits here, you'll see those oil temps over 240 daily.

Where did you get your HFCs installed and how much did they charge?

I have a question for everyone that wants a SC kit. Why would u want a kit that takes away engine power to make power? Is it because it's cheaper than a TT kit? And if you could get a TT kit for the price of a SC kit would you purchase it?

I think the difference for those that want a SC is that they dont want to tinker with the kit once its installed. Turbo upgrades have a tendency to require tinkering to keep them up and running. I did a turbo upgrade on my fisrt Audi that already had a turbo and it still required tinkering here and there to keep running right. SCs from what Im hearing dont require as much tinkering. Trust me these TTs will be getting boost leaks, blown valves, need new higher qaulity hoses so they wont get tuined by the heat, etc..

And taking power away to make power, I guess thats what you got to do. Im assuming you mean that the SC is belt driven thus taking some power away but it puts alot more back so you are still ahead in the end.

Plus cost is a major factor.

In my OPINION....
You can gain the same power goals with a supercharger UP TO A POINT. After that point you have to run with Turbo's. For anyone looking for 500 or less and they know thats pretty much all they will ever want its the best bet.
Upkeep on a turbo system CAN be much more of a hit on the pocketbook.

Also the power band on a supercharger is much more linear. It feels more like a strong V8 pulling all the way through from start to finish. The turbo generally has a smash you back in your seat feel after a certain rpm.

The turbo systems generally put alot more strain on engine components because once they spool its nearly instant torque and HP, whereas a supercharger builds boost with RPM's. So a turbo may see its 8 psi of boost at 3500 rpm, the supercharger wont see that 8 until it gets to the right rpm to spin the compressor fast enough.

For me I really see no need in anything over 500whp because the setup you would need to put the power to the pavement would cost more than the system you are putting on it. Along with the fact you then are getting into that range where reliablility is going to suffer. You can brag about having 7 to 800 whp but what good is it if a 300 hp car hooks up and leaves you at the line. If I can find it ill post a vid of me demolishing an 800whp civic on MT's with my 330whp 350z on bottle(at the time).

Turbo systems also create ALOT of heat in the engine bay. I dont want anything next to all my wiring and fluid lines that turns red hot. With my Vortech I could run hard for a while.... open the hood and still be able to touch my supercharger... not for long but I could touch it.

Those are just a few reasons I can think of but there are fan boys on both sides of the boost spectrum. I have owned a turbo car and my Vortech 350z.... When I boost my 370Z (when I get it) its going to be either a rear mount or a supercharger. I will stay away from the TT... its just too much money and time along with more worries thrown in the mix.
