First Hand Experience with GT-K Turbonetics Any of you have FIRST HAND experience with Turbonetics GT-K turbos??? I am planning to use the 650's in my build but I am being told on another forum they are crap and take forever to spool up. I would like to hear from any of you that have installed them....particularly in a large cubic inch motor. Thanks for any info! Here is a pic......

But got me a little concerned when I heard from five different folks in a little over five minutes. I have never heard any thing bad about them until that point. Thanks guys for your comments and I will listen for more.

heard from a couple of folks who put em on four bangers. Yes I know...what the hell do they know! But got me a little concerned when I heard from five different folks in a little over five minutes.

That said, a smaller engine will require a longer spool time due to less exhaust flow generated to drive the turbine wheel and associated mass. On your setup (you're building a 434?) they will spool up almost instantly.

As other have already said, our GT-K series is loved by many of our vendors and customers. That said, a smaller engine will require a longer spool time due to less exhaust flow generated to drive the turbine wheel and associated mass. On your setup (you're building a 434?) they will spool up almost instantly.

I have yet to hear anyone with first hand experience on vettes or other larger cubic inch motors say any thing negative. I am still very glad I made my decision on the Turbonetics GT-K model! Thanks for the input!

Course those 76's killed your motor....but I digress....I am looking more for power in the 3500 to 6000 rpm range....not so much at top end rpm's. I usually play around 3500 to 5000 anyway. Not looking to set record et's at the track just a nice streetable power band. They run out at 6500....I can live with that!
Matt.....its so obvious you have never had a stout turbo car. You are gonna have MASSIVE power at anyplace you want. After my puny Incon turbos, I built this one to tone DOWN the power on the street. You are in for a treat. It will be different than the blower but in places where you can really use it
