So, I had to get some data. I downloaded dynolicious for the wife's iphone, got a load of groceries, and with the wife, and the groceries, went for a run.
It was really rainy, not the best environment. I had a ton of wheel spin on takeoff, and kinda half assed it, then gave up in 4th 'cause I felt like I was pretty fast for conditions.
It ended up being a 15.4 at 97mph. Not bad for such a horrible run.
I'm looking forward to a dry day!!

Well, I finally got her working pretty well. The boost is pretty solid at 8psi. She goes pretty good.
I think I'm a little lean, so there's some tuning to do, but it's getting pretty damn good. Pulls out past 5k, really nice between 3 and 5k on boost. Chay |

Update: I've been having wastegate problems. I plumbed the damn thing backwards! It's oscillating. Well, live and learn.
The good part is it pulls hard again! I had multiple issues with boost leaks and exhaust leaks pre turbine. It sure spools now!!! The intake change did cost me some flow, but not nearly as much as I had thought. Hopefully I'll have her RIGHT soon! Then, autocross! Chay |

If I could find a 3.4 Camaro intake I'd try it, but I think I need to go back to the dual tbs on my existing intake. At 10psi it pulled well, then fell on it's face at 4k+rpm. Just not nearly the free revving machine it was.
Just waiting for some gas, then I'll fire up the tig! Chay Edited by CFoss |

Now that you're DIS have you considered the 3.4 RWD intake? I think
it's supposed to flow better than the fiero one. I saw your car the other night in Duncan. Sounds good! |

Well, I finished my intake..took it for a spin and I'm really not happy with it.
The single throttle body and associated piping has cost me lots of top end. I can't believe how much actually. The engine hits the wall at about 4200rpm...boost helps but is not a fix for poor air flow. It is way more driveable at low throttle settings, but it's not a tradeoff I'm willing to make. I'm waiting for a bottle of argon, and then I will be restoring the dual setup. I think I'll stick with the early 90s cavi throttle bodies though, they are easier to work from a few perspectives. Onward and upward!! Chay |

Got totally sidetracked! I had to go to Van for a course (I'm now cert. in fiber optics...cool stuff). To make the best of the trip, I bought a gigantic old welder, a Miller 300a. 850lbs of welder, and the power to torch almost anything! It even has a build in high frequency source, gas and water control valves built in.
It came with 4 tig torches, a mig spool gun for Al, standard stick welding stuff, gas regulator, plus a TON of consumables: 4 1 lb reels of Al, more tungstens than I can count, tips, gas lenses...unreal. Can wait to get bust finishing off the changes to my intake tract. Now that I have a good welder at home it should go WAY faster! Chay |

The alt was acting like the reg was shot...lots of voltage spikes and when loaded the volts would droop.
I checked the connector a couple of times, and it was fine. When I took the loom apart the neg wire on the field (alt black wire on the small plug) was broken about 18" away from the plug...so yeah, no field on the alt, it was just self-exciting to the point it was barely working. It may be a week or two before she's back, but I'm moving in the right direction anyway! I really wanted to do this stuff before winter so I didn't have to be doing it in the rain...it's worked out well so far. Chay |

Well, I found that the alt wiring wasn't correct, so I fixed that. I think the alt will work like it should now.
I pulled the engine and that allowed me to switch to the vband on the turbo manifold, do the clutch, fix the vss sensor, fix a turbo oil return leak, modify the intake manifold back to a single throttle body (I used a 91 Cavi TB). Now all that is left is to fix up the turbo to throttle body connection and reinstall the engine. I'm completely rewiring the engine bay and installing a terminal block between the engine bay and the ecm plugs. This will make it easy to wire, and provide an intermediate point for connection while troubleshooting and hooking in auxiliary devices like the wideband etc. It continues... Chay |

Well, I've decided it's time to take the car off the road for some needed tweaks.
1) New alt 2) New clutch 3) Better exhuast coupling on the rear bank (vband) 4) Get rid of the dual throttle body and go to a big single 5) Engine bay cleanup, rewire, reinstall the DIS module 6) Fix my VSS sensor 7) Investigate lowering by 1-1.5" 8) Make better supports for my cold air induction Should be a good couple weeks in it!

I got it from Maxwell's. They had a bunch in the back on the rack. Nice guys to deal with and they tend to not bend you over the counter like Blacky's.

Hey Chay where did you get your DIS pack for $60? I'm in
need of another set since I burned out the ones in my Firebird I think from too much heat from one of the manifolds. |

I've read a lot about them as well. I almost went Spec, but then I read about their solid hubs exploding and their sprung hubs coming apart...
Long story short, Clutchnet seems to be the way to go.
