Real Fiero Tech

Nope, that didn't fix it. I raced a camaro tonight and took a log. I can feel the car surging but stayed in it anyway so I can see what the data was doing. The car is 4.0 bore iron block, bla bla, i didn't listen. It has a big cam, headers, cut out, and I didn't care what else. He was willing to run...

Ok well I was finally looking over the car to try to get this figured out and I realized that nut on the stud I was using for ground had come loose. I welded a stud to the frame and connected 'all' my ground points to this one stud. I have a ground from the block to this stud, from the battery to th...

Couldn't you just adjust the balance a bit more to the right so the right side is a bit louder?

Why not just weld it and redrill?

Fieros can't lose, must clearly be the driver...

I wish I had the extra money to do that....

I've just been reading that the prom chip can vibrate loose in these AEM boxes too. I'm gonna pull it apart and make sure its seated fully. Good suggestion.

I was running comp cams 105# springs before, now I'm using 130# comp cams "918" springs. They are both LS1 style behive springs. I also use their OE-R lifters, but I'm using stock rockers and pushrods, which could be causing the problem. I haven't checked compression or leak down,etc. Next...

I watched my vids, I don't have that noise like the NSX. I'm gonna have to just take it easy and keep upping the boost little by little to see when it starts and what causes it. The AEM is controlling my boost and everything else. The plug gap is .036 right now, which I don't think should be out of ...

Okay, I looked at my other graphs that had worse lean spikes, and the power still isn't dropping off that bad. It does fluctuate slightly, but that must be due to the afr (roughly 5hp). Another thing could just be that the cal corrupted. We noticed some of the logging parameters were being weird and...

The "misfires" occur in the upper rpm region where the power kinda flattens out. The lean spikes in the AFR graph are representative of the roughness. I hadn't touched the timing at all at this point. The ceramic was not bright white, it looked nice. I have the plugs in the car still, sinc...

Got back to the dyno to do some tuning. I changed around my setup a bit and decided to put the car on the dyno for an hour to dial in fuel and timing. I must say the car is making MUCH more power, but I think I have some misfires or something. We ended up cutting my dyno session early so I can look ...

One of the springs popped out.

I bet you really got to rip on those things getting on the highway....

I know you checked this, and probably not the case, but my engine used to get a squeak when the nuts on the engine mount loosened up in the cradle. I got a socked up in there and the squeek stopped.

My broken clutch also squeaked before it failed.

Opps. Never pulled the transmission. I haven't heard much from him lately either. I do know he still has the car and the trans hasn't been pulled but I don't know how motivated he is to do it. I'm pretty sure it'll get junked. I looked up pulling the cams but its a real PITA with the engine in the c...

How long ago was the bondo done?

He doesn't post on the forums any more. Hes getting more into diesel stuff and doesn't check either fiero site.

Looks like you might be able to use them under the GT nose to help speed the air up past the front suspension to the smoother mid section of the car.

An electronic magazine I read covered these things. They did a real world test and provided some opinions. The test was done in 4-5 parts/articles.
