Another GTM Convert: GTM Supercharged G37

-an interesting comparison of the Stillen and GTM kits.

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

Keep on topic!

The GTM kit, however, seems to have better torque numbers from what i read.

I have run my car down 1/4 mile against stock 370's and i only beat them by .3 seconds. Granted, if i were using slicks, i may get a full second faster.

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.

SPOHN · 06-11-2011, 02:02 PM

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.

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, $8k installed is different, I thought you were referring to the cost of the kit. your numbers were close to RCZ's then, did you dyno your car stock on that dyno? As for 335tq being low on a dyno jet, compared to what? From what I've seen the GTM stage 1 SC put down similar torque (just look at the dynos GTM provides, +90 tq over stock), and looking at graphs it comes on in the same manner (linear of course). The only time ive seen the SC kits making more torque was with stock cats, which apparently won't last long due to the power/pressure? Looking at the facts I don't see how these kits are not comparable.

wow, what a mess!

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

Osiris · 06-11-2011, 02:57 PM

unfortunately i don't have a stock dyno. I can only base my statements by the experience i've had with the kit on my car. As far as the torque goes, maybe 282tq (mustang dyno) is all that can be expected from this kit. Either way, the performance i am seeing now was not worth what i spent IMO. Barely pulling away from stock 370's down the 1/4 mile and on some, um, "spirited" highway pulls with other stock 370's was not worth that 8k. And i have videos that show me vs stock z's. But at the end of the day, if i could go back and do it over again, i'd do it differently.

don't worry, you're not the only one. i'm sure everybody would had done it differently if we'd all knew what we were doing in the first place. just think this is a good starting lesson.

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?

Church!

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.

The reason for the low torque is the rib set up that stillen uses on the back of the blower and bracket.This causes slight belt slippage ,and the power to come on later in the power band.

can you elaborate more on what the "rib setup" is? Can it be changed or modified in some way?

Take a look at my thread Custom Stillen 370z supercharged

There is a picture of what the cog pulleys look like in there also you can look at my dyno graph.When you look at the graph look at the how soon the WHP and torque come in,not just the peak numbers.
