HOW MUCH BOOST WITH FUEL PUMP REWIRE AND 14b

[Birt96gst]

How much boost can I get with a 14B and a fuel pump rewire?

12-14psi no more. Make sure you have a boost gauge.

I am running 12 stock you saying I can't run any more?

I'm running 15lbs right nows, get a logger and see where you're at. Each car is alittle different, don't run over 17psi without some kinda of tuning device though because you will come into some serious knock which will make your car even slower.

nothing over 15psi on 93 octane. any fuel management?

Well i got a little boost happy with my rewired fuel pump, and this is what happened.

i wouldnt recomend over 15 psi.

i had mine at 17 psi with the stock fuel pump, not rewired. it was crazy fast, and its also a crazy fast way to kill your engine. log your knock, turn your boost up slowly and once you get knock, turn it down until you dont have knock anymore. thats how much you can run. i doubt it will be higher than 16psi
