Tial 50mm blow off valve
Tial 44mm wastegate
Hallman manual boost controller
2-bar map sensor
Fuel system:
Aeromotive adjustable FPR
60lb/hr fuel injectors
Walbro 255 pump with hotwire kit
Drivetrain:
Built 4l60e
Yank 3,200 stall
Midwest Chassis fab'd 9"
Strange aluminum center section

He laid down 645rwhp (thru a stalled auto with fab 9" rear). That's all I know right now. He had a shop tune it for him, so I believe he wasn't there when it was being tuned. As soon as I get more details (like boost level, tq, etc.) I'll post up.

Best run was 643hp/627tq @ 15psi and fully heatsoated is 626hp/618tq. Quick 2nd gear blast on the street.

Stall seems to flash to 4500rpm which isn't helping IMO.

Well, it also appears that the heads are homeported stockers that he was planning on upgrading down the road. I believe he has the ability to make more tq/power/quicker spool with more timing. He is not running a timing retard, so whatever his timing is in the last cell (possibly 21 degrees) is what he sees at every boost level. Thats a big drop in timing for 1, 2, 3, 4, 5,....psi.
Hey what's up.
I'm starting to think my trans was slipping in those videos. I noticed I lost about a quart of ATF from a leak I found the other day. Not sure if it was low on ATF when I made that video. I knew something was up when I was getting on it one day and it slloowly upshifted.
At first I thought it was spinning. But I got it to spin out for the first time from like a 20mph roll. I thought to myself, it's kinda sad that I can barely break the tires loose. But then I remembered the $4K in rear suspension I spent to prevent wheel spin
