Have a question about setting the boost with my MBC... When you say running 20 PSI max are you saying that you set it to spike and taper from there, or do you set it to spike at 21 and taper to 19.5-20 psi.... Right now I am hitting a max of 20psi in 1-3rd gears and am spiking at 21-22 for a sec and holding 19-20 psi to redline in 4th and 5th,... Is this safe, or should I turn it down a notch? 93 octane... + 1 gallon of Toulene to each tank (-:

 

You should be fairly safe with those settings. Actually there are pretty good. You may want to bump it down just a knotch for engine safety sake, but only 1 psi on spike; if at all. I run just about the same as you on stock internals.

Hope that helps a little.

 

You sound pretty safe. I run the same fuel, and spike 22, and maintain 21.

Happy Boosting.

 

Thanks guys.... I may try to turn it down just a tiny bit... Almost have it dialed in right where I want it..... (-:

 

my buschur MBC spikes to 23 dropes to 20 at redline, runs great.....

 

Evo8... That is a great trap speed. Do you have cams? What are your mods?
