Basically what I'm looking for is, who's has the most Horse power out of thier 2.8L Fiero with the use of a supercharger and or Turbo? As a few of you know I have been working on a 86 Fiero GT from Michigan that has a rebuilt 2.8L with some minor internal mods and it has a RSM superchager kit. WOW I said "RSM" When this car was brought to me, the owner Curtis York and his father Barth York had said to me they have been trying for years to get this car working right. First thing first I installed a boost gauge, Mr. York said to me when the charger was installed the car would put out 8 psi. of boost. Well once the gauge was installed I say at best 3 psi. First problem. Second I took a look at what was used for programming, well not much again. So after a few months I have installed a water to air intercooler, reprogrammed computer, installed knock sensor and modual, 2 bar map sensor, custom cranck pulley, custom blower pulley and idler, injectors and so on I got..... 235 Bhp and 291 Torque...... now the car hits 11 psi...
So all I want to know is who out if Fiero land has the highest horse power 2.8L Fiero? Looking forward in for your replies.
Thanks Joe

there is a dude overseas who is supposedly pushing ~500hp from his turbo/twin turbo 2.8. but he hasnt posted dynoes, and i honestly believe him about as much as i do calikid.

With 11lbs thats not that great. Are you running with the stock headers and exhaust? What does your A/F ratio look like on the dyno? I cant say for sure, but I think Orief friend got 210HP out his without boost, headers our intake cam and other mods I believe. It could have witha 3.4, but still. Oh and Orief got 200+ form his carbed 2.8 without boost. I hope you had the crank oil holes drilled larger running 11lbs of boost. I hope to get my intercooled turbo 2.8 (our intake, crane cam, MSD, 9.5CR, custom headers, ported etc) on the dyno this fall to see what i have.

Both engines (Carb'd and the EFI) had about 200 rwhp (197 and 204 respectively) which calculates to roughly 232 hp at the flywheel. (1 car was auto trans and one was a 5-spd manual) They were both 3.4L engines. These were NOT 2.8L engines.
The highest verified 2.8L horsepower I have ever seen was in a supercharged S-10 pick-up. The guy hit 275 rwhp on a dyno and the engine was custom built for racing. There was a guy who had a Datsun/Nissan with a twin-turbo GM 2.8L that was suppose to be in the mid to high 300hp range. (claimed, no dyno proof)

Well, I'm sorry to say "it ain't me". But I have a stock 2.8L with about 13,000 miles on a new long block. It is 203 hp with 238 lbs. torque. it has a KFG turbo set at a max. of 8 lbs. boost and has a water/ alcohol injection system made by Spearco, the intercooler folks. The water / alcohol injection is termed " the poor mans intercooler". But it works and with this set up on a stock engine, I am probably safe. All I wanted was something to bring the 2.8 to life and this set up does it for me. Ed

the people that ported my heads, Falconer (Will was selling these heads) , were getting 280hp (not sure if it was wheel or crank) but they were still putting out 100hp/L.

I am only able to go by what was claimed about my car. --3.2 stroker/turboed/intercooled running race gas and 18lbs boost was supposedly around 300hp. {I copied this from previous owners website and make no claims of my own other than it feels crazy fast when you get past 4,000rpms} "3.2L turbocharged, blueprinted, race-tuned GM V6 engine (original 3.1L) Custom air-liquid heat exchanger (intercooler) Max Boost of 18 PSI (race fuel required) Redline @ 6,800 RPM Unknown engine HP. Vehicle Dynotested at 335 RWHP"
add: it is only set at 5-6lbs now and running on premium.---Plenty for this old man.

Thank you guy's for your reply's. This car was brought to me with the engine allready rebuilt and the Vortex supercharger mounted. From what the owner has told me the motor is a 3.1L stroke which right there is not good. The pistons are dished which right there lowers the compression dramatically with the Fiero heads. The cam is from Crane or Comp. Cams, the headers are Sprint from The Fiero store and the stock cross over pipe. The exhaust is a poor make shift item that should be re done 2.5". I found out last night the fuel pump is stock, this we will be changing today. The only thing that we have done to make this better was the install of a water to air intercoller, larger injectors, knock sensor/ module, 2 bar map, chip programme, crank and blower pulley to get 11 psi. I would like to post the dyno sheet but I have had no luck in the past to post pic's on this forum. At some point maybe some one can help me out.
Back to the motor, the heads are stock untouched, stock valve sprins, stock rockers, stock intake, stock ignition, 3.1 crank and rods, stock dished pistons, stock fuel pump, Centerforce clutch, 4 speed tranny, stock cross over pipe, sprint headers, crappy exhaust.
The car will go in for another dyno run on Munday or Tuesday, we'll see what happens with the new fuel pump.
Thanks Joe

This is my car at Race Tech and I thought I would add so everyone knows the intent of this car was just to make it a little spunkier than stock. It is a heavy Custom show car and thats about it.
I got..... 235 Bhp and 291 Torque...... now the car hits 11 psi...
I would like to correct myself. I made a mistake on the wording of HP. the power out put to the Wheels is 235 WHP. When I said Bhp I ment to say wheel horse power. Sorry for the poor wording.
thanks Joe

U B*ST*RTED any who
Since we r on this subject..I can safely say the best way to make HP is thru the heads..NO HYJACKING HERE
But i do want to know what r some of the best flow numbers people have using the stock ported cast iron head and the hp reached..why u ask? it is simple if they r not worth it then i am not going to finish the custom intake i am build and just melt it down and use it to make some alum plates

I tried last night to scan the dyno sheet from my fax/scanner/printer to my computer and no luck doing so. I'll try again later to day or find out if my PC has the programme to perform this task. Sorry for the trouble I'm causing for every one.

Hi Kurt, Yesterday your dad and Alex came down to pick up your car... I was wondering if your able to post up the dyno sheet you have. I know we did not do a third dyno run with the new fuel pump, the last run shows that we were running lean, we found out later from your dad it was the stock 20 year old pump in the tank. The horse power should be up a few from the last dyno pull you have.
Thanks Joe

Im sure the 2.8 can produce some awesume HP numbers if you want to spend the money and time. My son got well over 500HP (I think 560?) out of a 2lit MR2 he built. But he had to go with his own dry sump, dual injectors (0 - 6k and 6 -13k), DIY girdle, DIY intake and headers, Electromotive eng magement system and lots of other very costly goodies. Near any engine can be made to scream and live if you have the know-how, money and guts. Guts, because you'll likely break lots of exspensive things in the process! The dang thing even blew up a $1k+ kevlar clutch at the track! He should still have pictures of the engine and car on our site trueleo.com. It was in two isses of Sport Compac mag.

that doesnt even look like a running engine.to get that much hp out of a 2.8 ,the only stock thing on it might be the block itself. i dont think i buy into that being realistic.

Hmmm.... the pan don't look like it will accomdate a girdle and without one 750HP should easily tear the bottom out that engine. Creative people can do funny things with dyno data. Like to believe it though. Bad looking engine for sure.

I read an article about the engine and i believe it was built by cosworth. I'm pretty sure i remember the total cost of the engine being around $80,000 US. It was built to get outragious horsepower for some race car but still retain the original engine status.
highest output 2.8 i've ever seen on the net is this twin turbo 2.8L that dyno'd at 750hp at the flywheel.
Those must be 3.1L aluminum heads, with either 3.1 or 3400 pistons in it now making it a 3100 or 3400 motor? Something like that could fit into a fiero as long as it was stretched a bit at the fire wall. Cool picture.
