GTM Performance Engineering 370Z SUPERCHARGER KIT PRESS RELEASE

The big issue for me is reliability. A air-water intercooler failure would be no fun at all.

One of the reason for me going SC over TT is that I wanted more reliability without having to constantly tweak things here and there. And from what I have heard SCs are more low maintenance than turbos. So with the IC, and Ive had FMICs before and I know they are tried and tested and true, the less moving parts and the less parts are a a major advantage for me.

You two are right on, with that being the real benefit of the air to air, less moving parts is less chance of something breaking.
One thing to keep in mind though is although annoying if the air to water cooler system would break, you won't blow your engine right away. Additionally almost every car now a days has water cooling for the engine, so the principle is pretty tried and tested.

I wouldn’t be too concerned about the charge air cooling method for system reliability.
There are more important items, such as a quality charger, a good pulley set up (stable and belt wrap), a good integration into the car as to not restrict other components functions and many others. In the end I’m sure both systems will proof to be reliable systems as they both seem to have covered their basis.

I’m sure you’ll be more then happy with either system.

True that, GTM has stated how much belt wrap they have, I asked Stillen and got no reply, so I dont know if they just didnt see my post or dont want to reply. I think GTM said 80% belt wrap, and Im assuming thats a good %.

Yeah, I don't think you'll have any belt slip issues with the GTM kit.

80% is kind of a strange way of putting it, as you would normally state this in degrees. But 80% would be 288 degrees, I've looked at the pictures, but it seems with that pulley they have about 240 degrees wrap.
The 80% was probably with a larger pulley then the one in the picture, or it's just the angle of the picture.

The "rule" is that if you want a minimum of 180 degrees. Higher boost level means it needs more power to operate, so the more belt wrap you would want.

Although even harder to see on the few Stillen pictures. It looks like both systems meet this criteria easily for their set ups. So both systems are more then adequate to meet this design criteria and you shouldn't have any issues here.

so belt wrap is no issue with either kit, both put out about same numbers give or take a few, same price range, but I still like the fewer moving parts for reliability so I will be going GTM when I do this. IM sure the other kit is a reliable one too but Im just more comfortable with the GTM kit right now. Nowing my luck and the local talent here for installs I would get one of those installs we had a month or so back in here (Im sure we all remember those threads) and would be running down the street and my water pump breaks or something like that. So gotta go with fewer moving parts. I think if the car came stock with the air to water and was completely covered under warrenty and all it might be good but I got to go with the tried and true FMIC and for other reasons too.

We would love to install it for you Give us a call.

Zsteve

you would come down here to install it? At no extra charge? lol

Hmm, that will most likely not be possible, lol. If I didn't have a business to run though, I really would! Working on cars = FUN.

Xan

The kit should be reasonable easy to install and I'm sure it will be a blast to drive!

Like I said before, I'm not here to sway anybody in any direction.
Just sharing what I know and putting things in perspective to help people make an informed decission they feel good about.

No doubt, both kits should sell pretty good, especially after a few installs from members here. Having options is good for us as we can get things at better prices and hopefully better quality. Cuz its really all about the consumer, us.

GTM, Stillen just threw out some stats and facts about air to water over air to air.

Listing all the oem manufactures that used water to air setup is great but how about some real info about the stillen set up like radiator,size,location,capacity of the system, how about some pics of all that. Why is it left out .Notice how much info we have shared so far. I mean they are about to send their kits out next week and they have not showed a single pic of their system yet , i wonder why ???

I choose air to air any day over liquid to air, it is simple effective, reliable and proven unless we were designing a root style supercharger kit .
