Blowthru GM MAF or SD for 650whp

[rr06rs]

Just wondering what the limits are with a blowthru setup? Build is in the works and looking for 600-650whp and I'm just wondering if I should stick with the blowthru that was used on the setup I'm running before or convert to Speed Density. This is going to be on E85 with 1600cc injectors, twin 255's and DSMlink. Turbo is a 35R

Blow thru will be just fine!

However 1600's are a lil small for e85 & 650whp

SD is the way to go imo. I love it!

I would go SD over blow thru. There's some issues with the GM MAF that won't be seen using an SD setup. Most problematic is the change in tune with the weather on the MAF. Plus it'll look so much cleaner in the engine bay with an SD setup.

I'll be running SD here by next weekend. Gettin my Maf fine tuned so I can swap over. So far k have heard it is the way to go! I'll be e85 but only shooting for 400-450 on 1250s

I would go with SD. 1600's will be fine if you have enough fuel pump to back them up.
