Im really waiting for the Stillen dyno on the Z to come out so I can see how their tq does. Right now I really like that GTM is over 300 tq from the 4K to 7K range and the Stillen dyno only hit over 300 tq at one point and was way under most of the time. I hope that changes on the new dyno on the Z. For me Im more interested in avg tq and hp and having 300+ for most of the rpm range is great.

Im using a Excel to map the differences between the two but I dont think I can post it on here as it messes up the format, is there a way?

here we go I think: If they are other areas I should follow let me know: Until Stillen shows the new dyno, the one they posted of the G is way below the GTM in all aspects.

good infow with the excel. Kinda interested in seeing the price for stillen kit.

Here is a comparison with the G numbers. I will put in the new dyno when it comes out.

Anyone know what dyno GTM used?

Also I wonder how the GTM will change with a full exhaust and CAIs?

you mean with a non-stock exhaust, since it already has it's own SC intake with the kit.

So far the only thing Sam hasn't given you is a stage 2 or 3 dyno with any sort of HFC or catback exhaust modifications to the car...it's purely been stock.

Stage 2, Stage 3 tuning is currently under development and test and you probably won't see dyno's with non-stock parts from GTM until those are finished. But I'd have to ask Sam this question specifically to know if that is true or not...I just know what he's working on now and it makes sense to continue with that work first before beginning to switch out stock parts and tuning with that setup.

Yea your right with just an aftermarket exhaust. Im wondering how much hp/tq we will pick up with an aftermarket exhaust, yea cant do CAIs like you said. Did he say what type of dyno it was?

I would say its a VERY safe bet to assume the Stillen kit will NOT be cheaper than the GTM. GTMs $5k intro price shocked everyone. I hope Stillen follows suit and offers a very agressive intro price, but with their new intake manifold, air-to-water setup, etc Id be amazed if they matched or beat that $5k price point.

And laid to rest:

GTM 8psi

Stillen 7.9psi

I think we all know who the winner is here.

Keep in mind, Red370, the GTM's on stock exhaust and Stillen has a cat-back exhaust. I'm sure we'll eventually see what happens when they're running a cat-back also.;)

Only time will tell, I just cant wait to see the stage 3 kit from Stillen, imagine, at 10psi? 500+whp EASY

Yep! We are...Both kits look great..Now for a side by side track day..;)

Well said.

when GTM adds its exhaust numbers will be about the same. The one thing Im curious about is still the Stillen cooler, with it being smaller, and I know cuz its water to air it can be, I just want to see if it gets heat soaked before the FMIC. I know FMICs do well but want to see some numbers on the Stillen cooler. I want to see some numbers on the GTM cooler too. Stillen was on the dynojet what did GTM use?

So if Stillen was to use 8 psi and not 7.9(?) how much would it gain? LOL.

I wouldnt so much worry about the inlet temps, both will be fine, however, for you auto guys, i'd worry about finding a good transmission cooler because with that much power, it will be needed. And for everyone else, an oil cooler will now be a must.
