Yo Antonio, wanted to share an article my best friend just wrote on the new GTX turbo:

B, thats a good article! Those GTX turbos really give at least 10% more power up top!

The GTX turbos when I get lucky, will be my next upgrade next year.
I spoke with Honeywell for sponsorship, but I was too late for this year. The guy told me to apply next year, and to continue to give him updates about my build, since he is very interested with the compound set-up.
He said that next year will be perfect since currently, they don't have GTX models for the gt28 and gt42, anyways.
Both GTX turbos will be plug and play for my set-up.
The spool time will be the EXACTLY the same if I upgrade next year.................but the mid range and the top end will definitely improve. If I upgrade to the GTX turbos, its not because I want more power, I just like the stronger billet compressor wheels

That's all.
I don't know, I really don't want to push the car more than 700whp, since the stage 3+ clutch can only handle about 550ft-lb (on the wheels). I can't go stage 5 clutch kit since my car will be a daily driver, and that stage 5 will not last longer than 4000 street miles, before I change it again.
So we'll see what the future brings
