Took my 04 to the dyno yesterday

I never said it wasn't. I was asking why you wanted to compare a car that is running E85 to one that is running 89 octane. ?

So, in your opinion, what would increase torque?

E85 is cheaper than 89

And I'd like to see your car vs a 3.4 header E85 car my guess is it wouldnt be pretty..........
 


E85 + a 3.4"...would be...a totally stock car besides the gas choice and pulley/tune?

It probably wouldn't make the same numbers. With the DP/U-Bend it'd still be pretty restricted, IMO. Would it be a decent race? Maybe.

But regardless, the cam/heads car would still pull up top. He replaced the big draw back of these engines: the valvetrain.
 
No I meant 3.4 pulley E85 and headers with open cone to support the 3.4 pulley should have said that in the other post.
I wish I could find more dyno numbers of that setup. IIRC Orangel67 did something like that and I believe it made over 300 HP and TQ.
Which goes back to what 99prixgt said better results less mods and less money.........

Keeping manifolds gives it the factory low-end torque curve.

Unlike headers...that sure, you might see gains from...but it's up top.

Not as useable on the street.

Magic and straight pipes apply.

I over-guessed a little bit. Not too bad of numbers from a stock pulley/injectors...with a cam/heads/DP. It'll really pick up some power up top IMO when you swap injectors...especially if you said they were running static @ 5100~.

Only thing I wouldn't do again is run a double roller...I killed the gear on mine...probably due to stupid low idle speed....but I'd just run a stock chain + some 130's and a higher idle next round.

What DR did you run?

There is a gain going with 150# springs over 130's on the XPZ...I'm probably no seeing it at this level though.

I'm not real comfortable using 130's on a stock chain. I'm doing it on my 01, but it's not something I'd feel comfortable running for 50k miles without looking at it. I have about 10k miles on the chain in my 01, so we'll see what it looks like when I pull it out in the winter.
 
Iraqtard you are arguing for completely diff things. So what he doesn't have headers. For what he is using the car for its a great running car and frankly he will for what he pleases with his own car. You now are arguing power. Must have missed the part were he states it's a mustang dyno. In which the shop itself calls the dyno "the dream crusher" in which it reads 20%+ lower than the dynojet in the same town. This car would freight train a 3.4/e85 setup. Get a new hobby.

No, it's not cheaper to run. E85 winds up being more expensive.



Since we're comparing things that have nothing in common, I'd also like to say that a H/C spray LS1 camaro would walk me from a 50 roll as well.

I don't think you understand what a PITA it is to drive as much as I do with an E85 car.

But with headers you'd be able to walk that camaro, right?

Ran a rollmaster. Had the gear chamfered...machined to sit at stock height, blahblah. You know the drill. Idle was set at 625~ with the Thrasher cam...lollll.

Right...I thought 130's were a tougher spring anyways...or at least harder on the chain. Can't recall.

I ran LS6's on my XP for about 40k~ and the stock dampner was ate to pieces. Chain was still fine though. Reptile and Trannyman Dave @ TEP ran 130's on a Overkill BBC Custom grind cam for well over 20k. They were fine...guessing higher idle speeds for sure...I think reppy's was around 900~. I'm not saying the aftermarket chains are bad, I just haven't heard of any stock chain failures when used correctly...but then again, I've heard good things from the aftermarket chains working as well. Just hit and miss I suppose?

This.

And actually...around here...E85 isn't much cheaper than 87/89 in most places.

You gotta roll out to BFE to get it cheap. Which then, isn't very cost effective.

That's what I did on this car as well. It's at stock idle now...which reminds me. I had intended to raise it about 100rpms.
Maybe the gear you got had some defect to it, that it caused problems.

I ran LS6's on my 01 for about 10k miles as well, before swapping over to 130's. So, there's about 20k on the chain and dampner total...maybe just a little more. It'll be interesting to see how it looks when I pull it apart. I have idle on there turned up maybe 100rpms as well, iirc. There are a few different dampners that are available for these motors, and I don't have too much research done on them, but it looks like some are better than others. Actual GM dampners may possibly be better. Just about every Cloyes dampner in a motor that I pull apart is broken.
 


I don't know what your trying to prove here, im just asking why because your setup dosen't make any sense. My top swap'd gt made 250whp on a mustang dyno, stock pulley just a gen5 top swap with roller 1.9's on 93 pump with HEADERS. Why did you go through All the work swaping a cam, springs etc etc if your not going to pulley down?

Could be...who knows...when I get home, I'll post the PB vids I've got of it when the front cover got ripped off to look at the clattering noise.

Yeah, I was running Manley 130's with Ti Retainers...had O/R pushrods with stock rockers. I know the Thrasher is slightly larger lift wise than the XPZ...you got a cam card for it by chance?

Not sure on the Cloyes ones...

I ran an actual GM one...tossed it in there with the stock timing chain at the time of the XP install. Someone needs to machine a billet dampner, maybe that would help? I also didn't know there were "other options", unless you were just meaning different brands/producers?
