These are the Final numbers for now, we could probably squeeze more out of it but we tuned it so it can be beat on pretty hard without having to worry. The car pulls seemingly forever, i just cant belive that this is my car now thats this fast. Im used to riding in other people's cars that are this fast but not mine.

Huge thanks to all the guys over at Haddad Motorsports, Mike, Brandon, and Dave were all fantastic. For anyone looking for anything high performance in southern california Haddad Motorsports is the premeir performance shop. Also big thanks to Lloyd Elliott for awesome port work and Bret Bauer for designing an awesome cam that everyone hates on until they see the numbers and feel the power (and hear the idle).

Heres the graph, Divide torque numbers by rear gear ratio to get actual numbers (4.10)

 

I'm not sure how a dynapack dyno compares to a dynojet, but on the #s.

 

1500 lbft of torque?

 

That's rear wheel torque. Divide by the 4.10 ratio shown on the graph to get engine torque at the rear wheels as blackz97 noted.

 

Nice numbers man. As soon as I get the $ that is the setup I'm shooting for. 355 with LE heads and a BB cam for around 400rwhp. Awesome man I am jealous. How are the street manners of that thing? How long till you get her to the track? Enjoy!

 

How about the story of my life! lol

Everyone thinks they know something about cams until you run one of mine. I'm not saying that to be cocky, just that EVERYONE thinks they know what specs WILL work and then when something different comes along they dismiss it untill it makes bad *** numbers. If I remember right the guys who built your motor are no dummies either, and they were really wondering about the cam specs as well. I'm glad we got everything worked out for you in the end.

Now team that up with Lloyds heads and you get what you are looking for!

Good power! I'm glad you are happy with it, that's the whole goal of this. Make power and make the customer happy.

Nice numbers, let us know how it runs. I will have some dyno #'s this Tuesday from my 355" LT1. Later Clint

 

Good looking numbers, have fun.

 

Tha certanly promising since im hoping to have my assembly finished and starting up almost the same combo in my garage tonight

 

Nice...

 

Awesome numbers, I cant wait to see how mine works out on my 383.

I got a custom from bret per my set up, i wonder how it compares to the other cam that are used in the LE setups.

 

Well i read that 8 page article that someone scanned out of a magazine a while back, it had a comprehensive breakdown of each style of dyno, at the end they did a pull using the same mustang gt on each brand/style of dyno and if i remember correctly the dynapack indicated the lowest numbers, some 20hp less then a dyno jet. I plan on putting it up on some rollers some time in the future but honestly after driving the car whatever horsepower indicated goes out the window because the car screams, bottom line. Besides I remember that article basically said that the dynapack was a tuners dyno because it has more capabilities as far as holding the car at a particular rpm and also setting the run length in seconds to obtain good resolution. Mike showed me a chart on the dyno that indicated that the dyno recorded a reading for every crank rotation during the pull. Sufficed to say that im glad that my car was tuned on a dynapack and ill go back to Haddad Motorsports to tune all my project cars from now on.

When you do the math it comes out to about 381 ft/lb peak torque.

I cant really comment to much yet cuz i only drove it once so far. ill get the car back tonight but its raining here so i cant really drive it. I can say though that the only thing that annoyed me is how the car spins the tires uncontrollably in 1st and 2nd :-P There is plenty of vacuum for breaks and stuff. It idles beautifully at around 1k rpm. Havent done much cruzing at all yet but so far its been okay, it bucks a little when you let the revs get low low but if its above 1500rpm no problems. I should be at the track within the next few weeks, ill post times, gotta get some tires tho....

 

Yep the Dynapack is probably the nicest dyno out there especially for tuning. The high end model which I think was used here is about $80K and is portable! Well they all are but the 4000 holds up to 4000ft lbs of TQ, which would work out to around 1000 rwtq!

The cool thing about those is that it finally looks like what a engine dyno chart would look like, not just a chassis dyno run on a dynojet. So you really do get much, much better info from them.

I think I saw your car there at the shop on Wednesday morning when Mike was finishing up the tune. The car did sound pretty nice!

I can't see your graph, can you just post the numbers you came out with in text?

 

Haaa! snorkelface! your the guy thats getting the insane turbo car built arent you? or was that supposed to be hush hush?? hope not....

Anyways the car was making like 403hp and 381ft/lb very consistently the last several runs as we were finalizing the tune.

Good luck with your ride btw, it should very nice :-D
