I recently rebuilt the engine in my 5.0. it only has a couple hundred miles on it now. The problem is that I used to have 10psi of boost@6000 and with the new set up I only get around 6 maybe 7ps. I checked all the hoses and changed the pcv valve, my only suspicion left could be the bosch bypass valve because the car did sit for almost two years. Could it dry out and leak?
This is what I had before...
holly systemax intake
v-1 sc
30lbs injectors
75mm throttle body
1 5/8 longtube headers
stock e7's
stock cam
stock bottom end
stock valvetrain
3.90 gears
255 fuel pump
This is what I have now
holly systemax intake
v-1 sc
30lbs injectors
75mm throttle body
1 5/8 shorty's
ported the exhaust side of the e7's
e-303
306 longrod w/ srp pistons
dual valve springs w/hardened pushrods
and retainers
and an Edge racing 3200-3400 stall converter
3.90 gears
255 fuel pump
aluminum driveshaft
I don't think these changes would increase airflow enough to lower my boost 3-4 psi, what do you guys think? thanks for any input.
