Real Fiero Tech

This is a dyno of my 88 Formula.

This was the setup I was going to run Earl(he has a 4.9 swap) with but he pussed out. Prob better that he did too.

Test was in third gear. It does 190 whp hp in 4th gear but I dont' have a sheet for that.

Here:

Mine did 197 whp with 238 # of torque. Swear to Bob, I have the dyno sheet somewheres. Should I dump my V6 and get a tractor motor?

Hell yeah! Thats not bad.

I cant wait until I get the tractor motor mods done and get to the dyno.

Here's what The M3 made... Not to big a difference over a Fiero with the Juice...

Dyno of Shaun vs a 4.9




the M3 Vs. Shaun






I would Rape a 4point9 on the highway.

You would rape a 4.9 period.

And awsome dyno runs. I saw a 4.9 dyno at 170ish at the wheels.

Don't often see a 2.8 curve that looks like that... no fall off at high RPM... nice.

That sheet was on the bottle, right?
Do you have numbers for it off the bottle?

yep those runs were on the bottle.

I have some off the bottle but I was running 19 lb injectors and lets just say that the readings are not an accurate representation of the power it makes off the juice. Its super rich and I lost 18 hp from the stock injectors with the 19 lbers peak but around 6k rpm i was down like 50 hp or something from the stock injectors. It was really bad.

I do have a graph of my car on the stock injectors but the tires are really out of balance and gave a bad reading on the dyno. the graph is really messed up and isn't worth displaying as once again its not an accurate representation. However on this graph the peak hp number was 110.

That's your peak hp number with the Starship Enterprise intake? That seems low. I've dynoed some stock Fiero 2.8s and they've been around 115 hp peak.

I assume this number was affected by your out of balance tires?

2.8

the whole run was messed up cause of the tires.

yea peak numbers dont' mean much really. its the powerband.

This intake might not make anymore peak power then stock but take a reading at 6k rpm over a stock intake and there are gains. Look at most 2.8 dyno numbers. The tq curve starts to fall at around 3700 rpm, and the hp starts to fall around 5k or so and once it falls it falls hard. I dotn' start to lose tq till 5k rpm! When racing that extra tq is huge to maintain it that high in the rpm band. I lose 5 hp from 5k rpm to 6k rpm. Only 5!. Stock intake 2.8's dont' do that. Mind you I am on a stock cam that is designed for 1k-4500 rpm range for making power. With a cam designed for more top end, like a 260 or 272 then it would be insane. It would prob keep climbing all the way till 6k rpm.

Peak numbers dont' mean shit.

unfortunately I dont' have a good run to compare to a fairly stock 2.8.

I have old dyno charts of my old 85 Gt auto with nitrous on it. The tq curve on that car did nothing but go down from the time the run started till the time the run ended. Horrible!

190 HP

Yup.

That makes more then your Patty Duke and your mouth COMBINED!


your roof wing adds about 80 whp right?
