Can it handle it??

I really hate getting sucked into these stupid arguments, but if you are going to quote facts, lets get them right. The turn key is $6300. lower torque numbers compared to twin turbo, sure, all SC kits make less torque. if you're referring to RCZ's dyno of 390hp/290tq, that was on a very low reading mustang, which he put down 256hp and a bit over 200tq stock. on a dynojet he put down 445hp/335tq in near 100 deg florida heat with the same setup.

comparing different cars/dynos is apples to oranges, my point is the kit obviously makes good power, and is capable of even more (squeeze did 470/360 before maxing out his MAF's).

When I was considering kits, I was on the fence about what setup to go with, i chose the stillen because I got a great deal on it, but I would be equally as happy with a GTM kit. I am not some fanboi, im just being pragmatic here.


what most people don't know about that setup is that one of the injectors that was in use on the stillen kit was bad, later confirmed by deatchwerks that it failed the flow test.

first of all $7-8k is what I spent for the kit and installation. And no, i'm not referring to RCZ's numbers...i'm referring to mine which were 390whp/282tq. And FYI, was the same dyno that RCZ had his tuned. So i say from experience with the Stillen kit, that the torque IS a negative factor with the kit. Even on the dynojet it's only getting 335 lb torque. This kit doesn't get any power unless you are in the high rpm range unlike what i've heard from others that have the gtm where the power comes on in the low end.

Ok I sat back long enough on this. For the last few days I have been rereading that post and yet on this forum I can't find anything about the situation. So I say this, can we get the full story on this situation? I do not know why this would be kept silant because people have been beating the **** out of stillen over this kit. You can't blame them if a injector was ****** up since they didn't manufactor it. Lets go please, I ask the owner to air this story out for the community since it is not fair for stillen to take the blame for something they have not control over.

Another GTM Convert: GTM Supercharged G37

-an interesting comparison of the Stillen and GTM kits.

Trips

Op requested info and experience on Stillen? Not a comparison between two kits.

Keep on topic!

Sorry no one likes my terminology. I just don't put gravy on it. It's my way of singling out the better system. When one unit is more superior than another, then that's what it is. That's my opinion and I'm entitled to it. Some of you guys act as I insulted you personally. Plus along with some of the bad customer service reviews I've read here about Stillen.

I just want people to have the best system when spending there hard earned money. And from what I've seen there's still plenty of people who are new to all this and just jump on the first kit they see without doing the long research they should. I've seen first hand a Stillen kit placed on a 350 and produce NO additional numbers. NONE. I also don't feel yu have to have a personal experience with a particular part to make a judgement call. Research, comparisons, and other reviews will allow for someone to make a fair judgement call.

So out of respect for all of you guys and the sake of myself, I'll no longer comment here. PM me if you'd like to discuss further. I'll call you if you like.

wow, what a mess!

Osiris: i think you need to upgrade to a TT kit if you're not satisfied with those power.

tomnavone

As someone who has had both kits on my car I can tell u there is a night and day difference between the two kits. Who cares if u get big numbers on a dyno if it drives like crap?

I got a Stillen sc, car makes 455whp and traps 121mph on the quarter. To answer your question, the rest of the car handles the added power nicely. You probably wont even need a clutch for a long time. I have 0 drivability issues.

That could very well be the impeller Squeeze...I don't think my belt is slipping...

Mr.Squeeze

All rib set up's have slight belt slippage the only way to avoid this is to run a all cog set up.This means on the front of the bracket as well,witch is something I would not do with this system.As far as the impeller goes it does add power under the curve,and peak boost.One thing it does not do is spin the blower faster this can only be done by changing the pulleys.The Stillen 8 pound pulley is the same size as a vortech 3.12 pulley there 9 pound is around 2.80.

The Stillen Supercharger uses a big pulley on the back this causes the blower to spin slower witch means boost comes in slower. I could show you a few dyno's from 350z's that use the same blower without the impeller.That have a better power band with more torque some with more peak power.All without the impeller.

We all know that Stillen made the kit around the carb tune.Vortech did the same thing with the 350z with the same unit.

FYI, I measured my 9 PSI pulley and it is right around 2.8". Do you know the size of the pulleys on the back of the bracket and the SC? My car is in having new brake rotors and coilovers installed so I can't measure it right now.

Mr.Squeeze

I'm not sure of the size of the stock pulleys that Stillen uses I took mine off and threw them in the trash. The biggest cog pulley you can go with is a 34 tooth jackshaft ,and 34 tooth supercharger pulley.

FYI if your going to switch to cog pulley set up make sure you order a 35mm supercharger pulley. The supercharger pulley lines up slightly off from the Idler and jackshaft pulley.

It's funny how it how mentioning "Stillen Super Charger" always seem to incite arguments.
