vortech supercharged vq powered s14 making 0 psi HELP!!
yea just wanted to update yall, thanks for the replies, but yes, i bought two large rubber caps at lowes quite a while back, drilled a hole in one and pulled a valve stem through the other. I started by capping one end of pipe at the throttle body, and then one end at the compressor, blew air through until it was firm, showed 15 psi...all held, next i moved the valved cap to the intake of the compressor, blew air through, all held...next i reconnected the ic piping back to the throttle, blew air through the compressor, held, except for a small amount that could be heard slowly whisteling through my valves, but my boost guage showed a slowly declining 15 psi but no leaks in piping or manifold...so yes that has been done, next
took the pipe with bpv off and replaced it with a solid section of pipe, held all introduced air pressure, went to drive it and it felt like utter crap...took off the manifold this weekend and saw that in the past few days a rodent has crawled up in and chewed off one of my injector wiring harnesses, so i had a cylinder #2 no fire, ill fix it tomorrow and drive it again, but the test with no bpv only yielded 1.75psi but i think this is due to how terrible it was running with fouled plugs and one solid missfire
sooo my idea on the camtiming was if it was off on one bank on the exhaust cam by one tooth it would cause a slight over lap that would seep pressure, but yesterday while turning the motor over by hand and watching the cams turn, i saw no overlap, but i could be mistaken
the thing is, is when i first started this swap the only available option was to run standalone, and you had to modify the cam angle pick up gear for the aem ems to get a good trigger signal, so i did that, around the same time, the company i was working with vqswap.com (who should be burned to the ground) started getting really crappy with me and wouldnt sell me a harness to run the ems? (yea it happened) so anyways, about the same time zfever.com figured out how to crack NATS and started making plug and play harnesses, so i had to go back to an original cam, whilst doing that, i dont know if me could have possibly misaligned one of the cams by a tooth or not, or if it was perfect whatever, the motor turned freely, idled super smooth, had great compression test results, but i always felt it was a little low on power, so i boosted it lol...either way, i dont know if this was indicitive of wrong cam timing or not, but even if it was just a little off, then it wouldnt be building enough compressive power if its escaping while on exhaust strokes and what not? i dont know guys, im just trying to figure out an explanation, im willing to take apart the cover and all that junk again just to really make sure the timing is dead on...what do yall think?
