To me it does, you pulled wrong information out of your hat to use in a debate. Like the "221hp" figure on page 11.

The results are close to what I figured, even on a pre-loaded dyno. Id be interested in trap speeds if you ever ran it in the Q, my guess would be ~90mph thru the eyes


Go argue with the Mustang owner then. If a Fiero weighs 2/3 of that guy's Mustang, other than the launch we seemed equal in power to weight, you do the math. Funny how that ~220 # keeps popping up..

Hurray! And it seems it was a 1999 Cobra (curb weight 3375). Anyone who thinks his power:weight ratio is significantly different from mine is crazy: @3:05 http://www.youtube.com/watch?v=OA0m-O8YLc0
Anyone who watches the whole event and thinks I'm making 149 rwhp is crazier.

From 1999-2003, I posted 4 dynos. 3 of them were 3.4 rebuild and one was a bone stock 88GT with 100k. The stock 2.8 did 112 rwhp.
The 3 3.4's read as follows:
142/203 (Crane CompuCam 2030)
146.3/201 (H242 cam)
149.6/199 (H260 cam)

So I think I know what 149 rwhp feels like. I also used to own a 1997 6 Speed Corvette. You guys are talk to me like I don't know what horsepower is. Dynos are subjective and you can only compare 2 cars on the same dyno and on the same day or at the track.

And I only posted this bogus dyno because I was asked to post this bogus dyno or gawd forbid the trolls accuse me of hiding something. If you can't figure out it's a bogus dyno - that the scaling is way off, I can't help you. I have video of me snapping 2 axles on 2 different occasions when I was running the 187/249 combo. On once of those occasions it was the bearing and axle at the same time thru the same line. On the other it was the Cobalt SS end ... which is supposed to be stronger than the Fiero end. Since then, I've kept my launches ~3k rpm.

Relax Lou, we are on your side! It's like a family, we argue and stuff but at the end we will be on your side when you need us. Just chill and rethink how to re-gain your power back and when you do we'll be as excited as you.

In 1999, I was running 142/203 - I had handling problems like I did against that Mustang and lost to a stock 1997 Firebird. I did a ~23 second lap. https://www.youtube.com/watch?v=A7FNo3L7dM8 (forward to 3:00)
I don't knock 3+ seconds off my lap time with a 7hp gain and 36 ft*lbs LOSS running way heavier wheels and larger...

In these 1 lap shootouts you have to run high tire pressures so they can come up to temperature fast or run a very soft compound.
Also your trunk is close and that steel manifold you have under there is heat soaking and killing your performance.
That is why my trunk is halfway cut, so the heat can go out without heat soaking the intake.
What kind of swaybars are you running? Spring rate?

I'm just running Fiero Store sway bars...and for springs, I don't remember what I got with the original HELD kit.
Handling is generally not my problem unless something has critically failed like a month and a half ago when my right rear wheel bearing wore out.

I know I can cut out some weight but i'm still entertaining making this a kit car once I finally get the 1st place trophy and retiring it from racing.

I am limited to 100 tread wear on the tires. I'm running Nitto 275/40/17 555R's on the back and 255/40/16 BFG G-Force on the front. I may actually reverse those to get a smaller diameter wheel on the back again to get my rpms a little higher.
My diameter is 25" when stock is around 23.7" so that is hurting me a little...

I have read the other aluminum vs iron threads and i follow this one as well. I believe with the majority that the aluminum head and intake are superior to the old iron. I would like to see you prove this wrong because keeping the engine looking stock but gaining hp would be awesome. I think you can go another route instead of all the negativety and ignore the comments and shut them up with cold hard facts. With PROVEN data not an opinion or estimate.

What's proven is that I did a 23.x second lap with 142/203. I did a 21.x second lap with 175/265 (4.9) and I've done a 19.x with this car. That is PROVEN. Dyno #'s are subjective. Flow #'s are subjective. Gaining a full second on this track is no different than gaining a second on the 1/4 mile. Every subsequent second takes more and more HP to get there. If it took 30hp to drop 2 seconds, why is it hard to understand that despite over-size heavy wheels, I gained almost another 2 seconds? If anything these wheels are bogging my launches and not letting my RPM go as high as they should since it's hurting my effective gear ratios.

I've had killer launches with smaller wheels. When I went to the larger wheels, I started having "bogged launches".

I believe I have an event from 2007 or 2008 on youtube where you can see 4 races from the same day and I was running a turbo 3.1 with 8psi. When cold the motor would make something like 225hp as it got hot it would go down to ~180 hp. My lap times followed from 19s to 21s as it heated up...and were directly related to my hp and my lap times increased every round. It's actually what made me go away from turbos in the first place. Inconsistency.

I think dyno numbers are the closest thing to objective and would go a long way to silencing naysayers.
