I just tested the car tonight with the twin 3582 turbos and didnt feel bad at all.I hit 16psi on the run.I run the sloppy stage 2 camshaft with a csu blow through 750 on e85.Not sure what kind of hp the combo would make at 16psi but didnt feel all that bad.Any opinions on what the hp might be is welcome..

yeah i hit 20 psi with twin 72s on a 4.8 but i did it at 7000rpm. do you know what rpm you got to 16 or any other rpm<>boost comparisons?

For comparison my 8.9:1 5.3 is likely making less NA than your 4.8. I made 560/600 on 12lbs. (non intercooled). Should be north of 600whp.

i will pay closer attention but seemed to be at 16 around 4500-5000.I shifted at 6900-7000 and it was feeling pretty good.I ran gt45s at first and they didnt get hardly any boost until 6500.These come on alot earlier for sure
