Think of it this way. If I am running 4000rpm and my turbos are throwing out 20PSI of boost but I have my tune and gates set at 15psi, the waste gates open up and direct that exhaust gas directly to the exhaust system.

A Blow off valve is kinda the same deal just on the Cold side (intake) of the turbo.

Mine will be a pre determined level, then open up to direct excess flow to the exhuast so I do not run too much PSI into the chambers.

I would like to see 15-18 psi at 2500 which shouldnt be an issue. Should be a beast down low. Top end will suffer from the charger, but it wont see over 5k too often.

250 shipped for a set of complete heads with valves, guides, ready to roll is a steal. If you knew you needed them sooner I would have made an extra effort lol

What do you mean it won't see 5k often?

My tranny wont be set up that high unless in drag mode. Way too many hills here. I should be able to pull up a 10% grade fairly easy with that torque.

If I dragged it, I would hope for low 12's to high 11's. I have way to much money in this to blow it drag racinging at 28psi.

V10's

The 2 V's are simple. All you need to do is take a BFH to the firewall

A 3V would be a challenge, personally, I'd need allot of help with that one.. Programming, electrical, dash components. - Everything has to work correctly, so, quite a challenge lol.

I'd need to cheat a little, - with a drivable doner to have what I'd need to make work.
