We will soon be taking orders for the STS 8.1 turbo. Just received this info from STS - The 8.1 Liter is working great, We will be able to start shipping 8.1 kits this week. We have kits for the Avalanche/Suburban and Pickup. The power increase at 5 PSI is an additional 120 horsepower, and 150 pounds of torque. It comes standard with the GT67 Turbo.

TBYRNE Motorsports will have an introductory price of $4175. though the end of April. This includes shipping in the 48 states. This system should be listed on our website in the next few days.

 

hmmmm maybe should wait tile gas prices go down if they ever do lol

 

what kinda power gains to the wheels and such are you guys getting with that kit

 

Cool beans!!! I think I'll lay off of doing a fogger system and do a STS instead. When I get ready I'll get a hold of you.

if i remember correctly, the 8.1 dynos at 340 lbs rwtq ( for get the hp, but i remember it was nothing great ) that would put it a about 500lbs plus id imagin it will help make up for that tiny cam and extend that power band. not to shabby. wonder what a Dmax intercooler ( since were most likely talking an HD ) an couple more psi would make.

Whos gonna let me live life vacariously ( sp? ) through them????

 

dang. 5psi and it made that kind of power. only thing now is instead of getting 8mpg it will be 4mpg... haha

 

Mileage might actually increase with this. That is something that the 8.1 needs

 

So far nothing on either website.
Is there anyplace I can shop for more 8.1/85E stuff for my '01 Yukon XL? I want to install a remote oil filter & maybe a cooler. I'm thinking about doing e-fans. And I'm wondering if there's any fix for the PCV system sucking the oil out of the system...
Sorry for the hijack...
Thanks,
