Well I spent the weekend trying to get my E-manage set up a little better, and playing with different spark plug combo's. For starters I was running NGK BCP6 plugs, with the gap set to around .028 and 15psi of boost. I was running stock timing and had the fuel curve kicked up about 18% above 6,000 (where the turbo really comes alive).
Well I decided to go to a cooler plug, since I had noticed signs of detonation a week before when I pulled the plugs (then I had a slight leak on my intake I think and the timing was advanced a few more degrees).
Anyhow when I got them out this time they looked fine, but I put the 7's in anyhow (1 heatrange cooler). The car basically ran like **** on them, above about 10psi it started backfiring and poping. So I took the gap down from .28 to .20 and it got better, but still not nearly as fast as with the 6's. So that night I ran it, had some issues with a line on my manifold blowing off while racing, but I still managed to beat a 12second turbo Z.
So I was starting to feel better about the car, when it started to backfire again.... and then to top it all off while I was at my freind's house the thing just died, it wasn't getting spark. It was like 2am at this time, and having just lost to a 14sec Fbody I was in no mood to figure out what was going on with my poor car, so I called it a night.
Next day it started just fine, then I swaped another set of 6 heatrange plugs into it and set everything back to where it was before. Then drove it and it was backfiring again, so I gapped the plugs down a bit more (because at 20psi it was blowing the flame out I think). This caused it to get a bit better, but not totally cleared up. So I started playing with the fuel maps, and ended up taking about 15% out above 5,000rpm.
Now she runs great, dosn't ping, and gets 28mpg highway again.
Now I get to look forwards to getting my cams set up next weekend.
I also managed to build a new intake pipe that dosn't leak, raise the redline to 8900rpm, and get rid of that pesky speed limiter that was bugging me in 3rd gear
All and all it's coming allong great, except the stock tranny just dosn't like to shift up around 9k RPM's..... and I don't have money for a new one just yet..... so I guess I'm just stuck to highway blast's in the upper 3 gears (from 50-100 the speedo spins as quick as the tach on a NA car in 2nd gear.... it's FAST).
anyhow, that's what's up with my project if anybody's interested
later,
Paul
