Hey, I'm having a handful of issues with my 95 mustang gt, the engine was rebuilt from.block up and has only 15miles of running time on her.
My build list consists of...
302 .30 over short block from latemodelrestoration
E303 camshaft from latemodel aswell
Procomp aluminum heads w/ upgraded 2.02/1.60 valves
1.6 roller rockers, hardened pushrods etc
Upper & lower intakes are stock to my knowledge
Has plenium spacer between the intakes.
65mm throttle body
19/lb orange top/stock fuel.pump
70mm MAF
Bbk long tube headers
Bbk x pipe
Underdrive pulleys
Smog pump/ac pulley deletes
MSD billtet Distributor
Now I am having overheating problems, loss of fuel for pressure under throttle, and the timing with spout connector out is good, but as soon as you put spout back in the car idles like crap, sputters, dies. But I don't think that's my issue.
Yesterday I performed a fuel pressure test, the results..
Fuel pressure at idle 40psi
Fuel pressure under throttle 30-32psi around 2500-3k rpms an it starts to back fire and break up..
FPR vacuum unhooked 43psi..an it didn't leak or smell of odor.
Car will overheat extremely fast, just sitting at idle. The thermometer will open up an fan kicks on.. I reused my water pump/radiator from previous engine, both worked fine. System has been burped etc
I know for my build I am pushing limitations of stock fuel injectors, maf and fuel pump. So I already went ahead and ordered 24lb injectors & 77m pro-m maf calibrated for injectors.
Do I need to upgrade fuel pump?
Am I back firing/sputtering for lack of fuel?
Why am I overheating?
I can't drive that car at all, backfires, sputters, hesitates around 2500-3k rpms, and then temperature gets really high ( at least on gauge cluster shows its running really hot near the L on 'normal' and sometimes past it)
What could possible be my problem? Thanks in advanced..
