After having the local shop Automotive Performance Engineering have to fab me up some custom brackets and arms for the billet actuators it finally went on the dyno.

Put it on last week but was blowing out the gap, I was going to be super busy so I told them to take their time.

Well today they regapped it and ran it. I don't have the graph yet, or alot of the specifics, but here were the numbers:

574rwhp
613rwtq

This is on a Mustang EC dyno, not a Dynojet. I'm going to run it on a DJ, but add an honest 60-80 to each of those numbers, thats almost 650rwhp and 700 torque.

Talked to a buddy who was at the shop, they seemed pretty excited. Pump gas and it blew the tires off until they restrapped it to the dyno, this is a double roller unit!

Pump gas, T37s, 18psi...that seems high, awefully high. I have a crimped mid pipe, that may lead to alot of backpressure...need to fix that ASAP.

Ridiculous amounts of fuel and hardly any timing at all, super safe tune. Aggressive tune, race gas and an easy 100-125rwhp more.

Clutch held great, no problems.

Anyone want to buy it <img border="0" alt="[pimp]" title="" src="graemlins/gr_pimp.gif" />

[Edited for numbers...seems the guy at the shop was a little confused on his numbers, mixed up the torque and HP, remembered the torque was higher and added it up on his own...]

That is really impressive.. Those are the #'s I would like to see on my car one day..

 

YIKES!!! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

It looks like Harlan may have some competition. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" />

Stock bottom end?? j/k..
Where is your mod list again??

 

Stock crank, Lunati Pro Billets, Ross pistons, ARE Stage II heads, 8.75:1 compression, Racetronix duals, 42.5lb injectors. Those are the biggies powertrain wise, it also has everything else known to man on the car <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Harlan will always make more power, can't compete with a guy who builds motors in his kitchen <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> He's more willing to break things. I was like that 2 years ago, now I just want to drive it.

After a test drive I'll probably turn it down to something that will hook up on the street...maybe...we'll see.

But now its complete, every little last detail has been ironed out, now it just needs a good wet sand and a For Sale sign.

Did alot to the car I didn't need to, iron block, Hals, etc...for a race car it was a good idea, for a street car its not a bad idea, but for a street car its also not a neccessity.

Sell it completed making good reliable power and buy a C5. No rear end to buy, no suspension.

Single turbo, clutch and make 500rwhp on a stock motor. If I can turn around the Camaro soon enough I'll pull the motor and build a light motor. stock crank, good rods/pistons, a nice light Stage I head with good valves, quite non-super wazoo cam.

Make 535rwhp in a 3200lb C5 that can be driven daily like the Camaro, will be faster because of the weight difference and a better driver all the way around...don't think it will hook up as well, no good DR's for the C5 available.

I'll do it right next time, didn't do it wrong this time, in fact I did it too right, invested in alot of things I may not have needed but I originally was going to drag race the hell out of the car.

So, anyone want to buy it, its only a Turbo 400 away from 9's most likely. If it went 128 with 535rwhp on the same dyno imagine what it will go with 574...nice stall converter, trans brake, G suit <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Congrats on the great #'s!
I hope you find the right owner that knows how to maintain a FI Turbo car.

You going FI on the C5??

I wonder what mine weighs now with the stereo and minor soundproofing..

Great numbers for sure.

18 psig?? seems like alot for those numbers to me, but on 8.7:1 dunno. I'm hoping to run within the next few weeks. Finally got my injectors and intercooler core.

So well have to do a dyno shoot out or something <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I think i have a dyno graph you can borrow w/ 600+ RWTQ by 3800 <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

hehehe

I'd watch turning it up much more on the 42's, there's not much more room with them

 

Yeah 18 seemed like alot to me too, but again on low compression I'm not sure, no one really to compare to, just you, hurry up dammit <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Vince is wondering how to build the motor, build it like Harlan is, and how I plan on building the next one. Spent money on good rods/pistons and valves, forget all the super whammy stuff, just force the air in <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Rob Raymer is doing a LS1 Single turbo for the C5 once the F-body kit ships, that is my plan as of right now.

 

Guys I have forged pistons and stuff. I just need to put different heads on the car and get my compression around 9.1:1. I am only planning on running 10lbs or so of boost. Nothing too crazy... I am sure my engine now can take 15lbs plus..

 

I dont mean to change the direction of this thread, but I dont understand how Rob is going to plumb a C5 single turbo. Dont you need to bring the exhaust together from both sides of the engine before the turbo? There doesnt seem to be any place for an exhaust crossover on a C5.

Eric

 

Better to ask Rob, however I do believe he already has done some mock ups without major issues using the major components of his F-body kit with changes in pipe routing for the C5 kit.

The thread has been edited. A buddy, Tom was at the shop while they were doing all of this. Considering Tom manages huge amounts of money for his company you'd assume he'd have a better take on numbers <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

He had the torque mixed up with HP, then thought well it made more torque than HP so he added to the HP number when I asked him the torque...the shop called me this morning and gave me the real story.

574rwhp
613rwtq

I had thought this morning about the numbers he gave me last night thinking they were awefully good for a LS1 intake, now this makes more sense.

Eitherway, any more power and I look at head gasket issues. 11.5 A/F ratio steady across the graph and only 17 degree's of timing at the top end.

Didn't get out to drive it, had them fax over a sheet. Will pick it up on Monday.

nice looking curve. You sure don't need much gear with that lowend torque.

 

You need a short runner intake like my soon to be finished Holley <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Gotta love boost <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

Thats a nice dyno.. It looks like you would be tearing someone up on the street.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

Is that the Aluminum LS1 Holley, but modified some?
