Just to give you some more info and problems you can run into:

5 3.8 SC
* Series 1
* Series II
* Series III
* Intercooled

6 V8
* 350
* 383 stroker
* LT1
* LS1
* LS2
* Northstar
* 4.9

If you want to do this equally then you have to put a line item for every swap that has been done to a Fiero. This includes sub-categories for Turbo, Twin Turbo, etc. Is the motor a pull out or a performance motor from GM, hot cammed or standard? Then again HP numbers on the dyno will have different loss factors if the car is an auto compared to a manual. There are too many variables to find out who has the highest hp for each setup since no two motors or setup will be exactly the same.

Just my .02

that is true

Front engine
trike
kit car

and don't forget Tracy's Blown 455 olds powered coupe.....

Not to mention dyno type (Mustang or DynoJet), weather conditions, and correction factors used.

A Mustang dyno using SAE J-1349 correction factors will return a substantially lower reading than a DynoJet using SAE J-607 correction factors.

There are way to many factors, this thread is really pointless.

well, I have seen posted dyno slips of a carbed 3.4 - oriefs - was 230 or so?
and, in another thread for a 3.1, I have seen 170 at wheels, meaning maybe 200 at crank

This thread is WAY too open ended. Just say whats the most HP for a 3800SC, 60*, or SBC. For most HP I'd say MotorTV's LT1 is probably the most powerful at what, 720-740HP? I dunno if thats WHP or FWHP. I think FieroX was working on a like 600hp 3800SC like ZZ performances 9.1 second GTP. Sean Hammit on RFT is claiming 700HP out of a turbo 2.8L but I don't really understand him so I dunno if thats a lie to pwn V8 owners or its true, who knows, its just what I read.

not pointless, most forums have a thread similar to this.

Fierox has the most dyno'ed HP of any fiero i have seen, but I have not seen many.



Matt Hawkins Turbo 3.4dohc put down 415 WHP, but he never posted a graph. I saw it in person, and I know for a fact that number is accurate.

well, mine doesnt exactly fit into any of the v8 catagories but we'll see after i get back from the dyno...

------------------
1987 Pontiac Fiero GT
418ci 'Mini-Rat' motor
dual stage nitrous injected
built 5-speed getrag

Hmm i wonder when they talk about all the factors at the drag strip like track condition weather condition tire width tire compound slicks or street tire or being at 1500 feet above sea leval or sea leval bermetric pressure on&on

Nick Wagoner's LSx fiero has been on the main page of PFF with dyno chart of 508 HP since Jan 11th 2006.

He was running a 3.4L turbo (until he killed some pistons due to his poor tuning abilities) But his real dyno was only 210.4 rwhp without the nitrous shot.
The 700 - 800 hp dyno's he faked just to try and harass a few people.

What you've seen doesn't matter. Unless, of course, you're willing to accept other people on their word for what they've seen.

That's about as likely to happen as you racing Archie.

I can post up my dyno plot, but the numbers are real.

My take on all of this. Darkhorizon is a decent guy. I met him at Milan dragway. He may comment a lot on these boards, but he is just stating his opinion. Just as everyone here does. I have not known him to lie about anything he has said.

I wish all this V6 vs V8 animosity would stop.

I like you but, I know you hate Shaun and I can't trust what you have to say about him until I see a dyno chart.

Sent you a PM with the links to his threads.

You fail to mention that he was also trying to sell a bunch of engine and trans fragment pieces, because his stuff just explodes after a short time.

here comes the flame war...

quote Originally posted by Mr.PBody: here comes the flame war...

Hell it's no flame, even X will admit he was trying to sell frag pieces to fund his new project.

frag pieces?

I dont quite understand what you mean by that, but the fact he still has his forged pistons that he started with, is a feat for the time that he built it in.

" In God we trust, everyone else bring data"

ive never fragged an engine, just blown some head gaskets. I blow up trannies. But you V8 guys wouldnt know what thats like. :P failed to exceed mechanical limits hahahahahaahahahhaaahahhahhahaha

this thread will prove to be interesting.

60e transmissions are might as well be made of glass when 400+ horsepower is behind them.

The headgaskets that the "big boost" guys try using require a bit of experience when your installing.

There are top Fuelers with 350 chevs with 2000-5000hp drop that in a fiero
only prob i see is the higher you build the motor up the more your head only 12 inches away needs protecting.

Realistic is how quick your car is at
0-30mph
30-60
60-100
100-200?
0-60
quarter mile

A sbc could be fastest set imo if built to about 400-700 hp as a guess from what i have seen.
Otherwise 3800sc is the way to really go lighter less power required to gain acceleration.

But even if you knew how a guy built a 7 second world record car you couldn't reproduce it exactly as there are 1000000 ways to take a shortcut, Bore, shaved cam, optimised exhaust, oxygen sensor, throttle, turbo lag anything and everything is a one off build. Everything down to the air mix is different even the cables..

who has the deepest pockets??

I could build a 8000hp Fiero if I had the cash

Within my means I could definately build a 800hp Fiero but prefer to stay sensible and use the car for IMO what it was emulated to be ..an American poor mans Ferrari along with my own personal choices to make it a balanced enjoyable car to drive in all conditions possible

Put this down under the N* category for now, hopefully i'll be able to get back on the dyno in a month or two or maybe someone else can take the lead. 300.5hp

edit: This was on an electric edie brake dyno (mustang i guess they're called)

How was the drivability??

quote Originally posted by Erik: How was the drivability??

Drivability was great. It's got lots of low end torque for cruising in the city in 5th gear at 50km/h and really sucks you into the seat above 3500rpm. This was with the old 5spd and pre-rebuild so we'll have to see what it's like with the 6spd and some performance goodies when i get it back together. I think for most fieros 300whp would be the perfect number for a balance of power and control, but of course i want a little more . Best 0-60 pull was 4.02s, i'd like to see it in the high 3's when i get it done.
