Finishing up my turbo setup this week and im trying to fiqure out what wastegate and bov springs ill need for using a boost solenoid. Im not sure on what power this will make, my guess is mid 500s on E85 not sure if tuner will use base fuel pressure or not
Motor is stock except for arp studs and act clutch.

Tial 44 wastegate and bov

Dyno tested, mine made 741 whp at 29.6 psi and we believe a little over 800 whp on 34 psi but that's not confirmed after we later turned it up on the street, which was pretty much maxed out.

For wg spring youll prob want to go with the lowest psi you are going to be running.

That is crazy. Forgot to mention ill only be running ID1300s. Need that good idle.

I understand that part, but how does that correlate to the bov spring? If I run a 8lb wastegate spring and boost up to 16lbs what do i run for a bov spring? a 16lb for both boost levels?

Spoolin

I just went with a Tial Q with either a 10 or 12 lb spring if I remember correctly. No issues with my setup.

so u were able to tune pass 10lb springs at 29psi with a boost controller? I am currently tuned at 11.5psi but my wastegate is at 15psi thats what my tuner said. Is that physically possible?

not sure if i am right but i think what ever your WG spring is.. you can boost 3x or 4x.. something like that.

nguyen365

id 1300 are nice. I have id1000. Ive seen 550whp e85 at 19 _ 21 psi before. 6262 ive seen get some great numbers . is your block stock?

Wastegate... depends on what boost solenoid you're using. AEM has a 3 and 4 port. The 4 port can stretch quite a bit.
I'd say use a +/- 14 psi spring setup



Use the solenoid to stretch this wastegate setup to 25psi or so and go kill your diff :P
