No I read it and understand it down to a "T" .

Prove me wrong . Chassis Dyno will tell , not interweb dyno .

What I'm getting at is most go into modding and expect big numbers , that's usually how we all get humbled .

Cam and converter are all wrong for a turbo

It also depends on which turbo he got from On3. If its the 76/68, then its gonna be tough to get that power, if he got there new 76/74 or what ever it is, then he might be able to get close to that power on 10psi but I'd still only guess mid to low 500's out of On3 parts at 10psi. BW is a whole other level when compared to On3 turbos...

I got the new 78/76. I'm guesstimating 17-20whp per psi

I'll be getting the converter sent back to Chris@CircleD to get it tighter for boost and maybe re-stall to 36-3800

I always wanted to boost my high compression 408 but was scared to do it. When does the kit show up? I'm anxious to see some vids

No lie I'm still scared to do it but what the heck. E85 and meth should keep it alive and I have good faith in my tuner, he pushed a full sized truck stock bottom end 5.3 into the 9's and just about every 4.8/5.3 he builds runs 10's(Tellez Motorsports)
Actually the kit showed up today to a friends house. Super fast shipping 2 days after sending the payment, unfortunately I'm out of town at the moment and wont be back til 2 weeks. But as soon as I'm back I'll try to have it done within a week.

right setup can easily make 600 rwhp on 10 psi but not every setup out there will do so

I wasn't on E85 when I had my 408 or I would have done it in a heartbeat. Should be a really fun combo when it gets running
