~!

Great pulls Ryan, the car is going to fly down the track! Too bad we couldn't turn up the boost, that turbo was begging for more boost. At least I got help by sitting my fatass in the back to keep the tires from spinning. :)

Stock Idlers I take it? What cams are you running? Nice numbers for the boost level BTW. Thanks for sharing.

Can you get into some detail about the differences in spool and power compared to the 77? I will most likely be upgrading to the 80mm as well.

nice numbers!

30psi at 5700rpm with the anti-surge removed. It will make 1150rwhp when I turn it up a bit more. 272 Cams this time around

My 76GTS made 30psi at 5200rpm. Made 950rwhp on avg, 991rwhp peak. 264 Cams

My GT42-76 DBB made 30psi at 5000rpm. 1000rwhp was the most I made with that turbo 264 Cams

The dyno sheet is in the vid. Just pause it and you can see it there!

And yes they were stock idler pullies of course!

Are you going to go with the SP forged pulleys?

Hey Ryan, Great numbers. Now turn it up to 45lbs and see what it will do.
