2C is great... But you could use a 3C with that combo .... I am working on a setup now for a Corvette with a F1C 5.3L 244/248 115 it made 900 with a 427@18psi before lasted a month... Time to show him how well a Junkie truck motor holds up

Mitch runs mid 11's on 10psi... and high 10s on 14 but i am sure a little faster now.. Can you footbrake any boost at all??.. That 3C would help that oversize turbo 5.3 combo

High boost setting (16lbs), no nitrous and street tires I can brake boost to 4 psi no problem and hit peak setting by shift change. On low boost (6-7lbs) its a dog without nitrous off the line and won't build boost for .

I'm interested to see your C5 outcome as well however.

BTW Chris at Circle D was the one who recommended this converter to me after many conversations. I just wanna throw the slicks and skinnies on and see what this polished turd will do

nice to see someone play with a 5.3 and with a turbo for once.
