Last time to the dyno (D&G Dyno, Hennessey OK), I made 548 hp and 531 torque at the tire on 24 psi. This time I am going to Wichita Dyno (people think Wichita Dyno reads 10% lower than D&G because of correction factor), with my new intake setup and hopefully running 26-28 psi of boost. Place your bets.

I say
575 and 555 torque on 28 psi.

That is a lotttaaa horsepower !!!!!

I'm predicting 575 thereabouts.... Good luck man and give it hell!! peace

Pete

I predict you'll be surprised.

580?

I'll go high and guess 594hp and 576ft-lb.
Good luck.

Not to hijack your thread , but 28psi? I would assume that my ls4 would come apart if I tried to put that much boost on it. What makes your engine able to handle it?

It's a 3800. /Solved.

The 3800SC was factory built to handle boost. It has goodies like stronger pistons to make sure it doesn't break under the pressure. They actually over-engineered it if you compare it to other engines. That's why they're so popular. If only they did this with all their engines/transmissions.

Well were back from the dyno. A couple of things happened with the new intake. First off it ran a little lean so we had to add some fuel. Got the AFR's back in line, then turned up the boost. All we could get was 22 psi of boost out of it. I even pulled the boost line off the bottom of the wastegate and all we could get was 26 psi. We ran completely out of turbo. The best pull was only 472 hp at the tire, on 22 psi boost. Then we find out that Wichita Dyno's dyno reads a lot lower than the one in Hennessey because of the correction factors they use. Chris estimates that I am making close to 700 crank hp. So I dont know what I would make on the dyno in Hennessey today, but the car feels a whole lot faster. Guess we will find out on Saturday.

quote Originally posted by fieroX: Oh and the reason my engine can handle a lot of boost is that I have forged pistons, forged rods, everything is balanced, cometic head gaskets and it runs on E85.

That's what I was wondering. Can't wait to see what happens Saturday!

So you plan on making a run on Saturday then? This should be interesting. I know Dynos are not set in stone about actual hp but they are great for tuning what you do have. Change a few settings in the software and you make or loose a bunch of indicated HP. The real proof is in the pudding as they say and if you rip the 1/4 then you will really know. If you are indeed pulling 700HP you should be into the nines pretty good no? Any ideas about why you could not get the boost up to the desired level? Good luck on Saturday man. Peace

Sorry to hear about the marginally unsuccessful run. BTW not fair. My prediction was for 27 psi.

I'd go to the same dyno for every pull... get more consistency that way

Where ya gonna run it? I want to see this puppy fly.....

You need to start videoing these dyno runs and put them on youtube. Heck, put your drags on youtube also. Show me something good! :P

Do you have a build thread, I can't seem to find it? I found an older one that doesn't appear to be current at all.

His drags are on YouTube

I dont think I have a build thread. Just random threads scattered amongst the internet. I will take my shop camera home and get a few engine bay pics. BTW been doing some plotting, next turbo will be a Borg Warner S372.

Just did a quick google. Good god that's a big turbo.

I cannot wait to hear how you do on the track.

So you ran out of turbo to boost, that is amazing. Since you probably ran the same turbo before and made great horsepower without running out of boost, you obviously are making more HP than before. It is just hard to tell how much more since you ran on two different dyno's. Your track times should really tell everyone what you are approaching in the power level.

I would love to be able to pull more HP than I am, but it sure gets expensive to add HP.

Good luck with your run.

I am running saturday at an event for the Blacktop nationals, and we are hoping to go 9's. I will have plenty of cameras on hand for the event. If anyone wants to attend, come on out to Wichita. Gates open at 5.

Geez, I wish I could make that road trip !!

What turbo are you running right now? With the new intake setup you are probably flowing a lot more and running out of turbo at a lower pressure.

Good luck at being the first into the 9's!

I'm predicting 9.89 @ 137

quote I say 575 and 555 torque on 28 psi.

Scratch that, 10.12@135 possibly 9's with a real turbo.

Dude I would LOVE to see that....peace

I am running the S362 right now. At 22 psi it will flow 72 lbs/min of air. That's aprox 700 crank hp. I think with the s372 and 28-30 psi I could see 70-80 additional hp.

Well then what are you waiting for? Pick that puppy up and get it bolted on... Are ya gonna make us wait FOREVER for a nine second fiero?? haha peace

An LS could do well over that amount of power.

Not in the Fiero world...I mean the 3800SC has been done over now many times and proven itself...Still waiting on the LSX crowd to prove it can hang with the 3800SC......This coming from someone that is doing an LS4 swap so not taking sides just stating facts....

At what point does everything else past the engine go 'ka-boom'?

quote Originally posted by pmbrunelle: 1000 hp LS engines are pretty doable 3800 fanboy.

So make one.. and put it in a Fiero.

Do you really need to stoop to name calling?

These are the silliest of debates. There is no question of the HP potential of a Chevy V8. The 3800 rules because it's a matter of getting the power to the ground without breaking everything. The 3800 is a better balance in a Fiero. Not so with other cars.

quote Originally posted by Steel: So make one.. and put it in a Fiero. Do you really need to stoop to name calling?

Because I would really install a turbo LS engine in my Fiero to satisfy you? No...

An engine doesn't need to be installed in a particular chassis to be "proven". Installation into a Fiero does not automatically imply a shitty exhaust, especially if you're willing to delete the trunk. The assertion that a powerplant must be "proven" in a certain car is ridiculous.

There was no need to beat around the bush, so I went straight to the name-calling. When the fanboys were saying absurdities about the power potential of an LS versus a 3800, I just stooped to an equal level.

We're impressed with a hotrodded 3800 producing 548 hp (and more coming up). It's an achievement. The same power with an LS, less so of a feat.

I agree but with this being the internet and a good place to waste time then why not over the 3800 Vs V-8.....I agree there is no question that the LSX can make a ton more HP than the 3800SC but there is not one yet to do it and put it to the ground. All someone has to do it build a high HP LSX attached to a built 65E and throw down some low 10 runs....There is already two that are on there way but not there quite yet but they will be........

How about a debate on what is easier/cheaper to get 550whp from?

...I guess it should be the same right? Just need a couple extra injectors and valve springs for the LS.
I think the formula is just get a stock bottom end, bolt a 700hp turbo on, cool it and give it some extra fuel. Right?

There are people getting a 1000HP out of a 4cyl volvo engine.....Whats your point? With less money invested than what a 1000HP LS engine would cost. That is irrelevant in this thread. At this moment in time the 3800 is powering the fastest fiero(s).
Congrats on shooting for the 9's Fierox. I cant wait to see the vids.
