Well, after a year of tearing down and building up my car, long conversations with Tony Mamo and many parts from Tony (so much that my bank called me to verify some Tony guy wasn’t taking my money without me knowing) I finally got the chance to dyno my car. I took my car to Patrick G for tuning and to do his thing. I want to say thanks very much to Tony for providing me insight and knowledge on LS engines and the parts he provided me with and spec'd together. A big thank you to Patrick and Kurt at LSXDyno for their patience and trouble shooting to get this car to run properly so we could get it tuned, I can’t thank them enough.

Here is a car and quick parts break down,

1994 Camaro
347ci LS1 11.6 CR
Stock Crank,
Pauter 6.200 Rods by Tony
Custom Wiesco Pistons by Tony
238/242 .605 .610 112+2 from Tony
ATI Harmonic Balancer
AFR 205s (stock)
7.4” Chromoly Pushrods
Stock Rockers
FAST 102 Intake Manifold ported by Tony Mamo
Nick Williams 102mm TB
Fast Toys 102mm LID
FLP Lvl 4 (Big thanks to FLP! Excellent Customer Service thanks for answering my many questions and support!!!)
Yank ST4000 (Big Thanks to Yank as well, excellent customer service and always ready to help and provide support!)
Stock rear, 3.23
1 7/8” Kooks headers
Custom 3” H-pipe and true duel exhaust with flow master single chambers dumped at axel made by me.

The pulls were done in 2nd gear except the first one, which was done in 3rd gear (3rd gear was simply to long of a pull so he decided to do the remaining pulls in 2nd gear). One thing noticeable by dynoing in 2nd is the tq is down around 15-20rwtq and (?)hp verses that of 3rd gear. Also, pulls were done with lid, air filter, and full exhaust(no cutout).

With all that information, the car made 479rwhp and 396rwtq in 2nd gear on a mustang dyno. I was very pleased with the numbers, and especially the tq curve, it seems to just hang on and pull, and feels that way from a 50mph punch! I told Tony I wanted top end performance and that’s exactly what I got!

Again, thanks to everyone who was involved and helped me with this build to get it done and running!

Nice results through A4 ..

This is the 1st build I see with 6.200" rod .. vs the common 6.125, what's the reason in doing this

I wondered the same thing??

Ever read smokeys secret recipies for power? Lol. He explains why going with a longer rod is better.

BADD SS

Most real world gains are at most only about 2% hp.

It increases dwell time of piston at tdc, and bunch of other stuff that may or may not pertain to this setup. The problem is, the result varies WIDELY based on the build.

Nice numbers either way op.

Thanks guys,

1st reason was convenience LOL not to mention I was ordering pistons anyways. Tony mentioned he had a set of 6.200 rods collecting dust hidden in his shop somewhere and by chance he found them. Tony is a better person to ask, but essentially BADD SS is right. Also, with the rods weighing in decently light and the lightweight wiseco's, I believe he was looking to take advantage of the light weight rotating assembly. The conversation was a year ago, but essentially the 6.200" rod could theoretically make the piston lighter, reduce frictional losses and stresses. I will allow Tony to correct me if I am wrong, sorry been a while

One thing I forget to mention this was done on pump gas, 93 octane.

damn, good numbers, and an awesome looking build. It's little things put together like the rods that make the difference. 2% hp increase in a few places adds up

I have to agree, those are excellent numbers and through an auto-trans at that. That leaves the question whether the torque converter was locked or not for the dyno pulls?

Nice numbers! Tony really knows his stuff and has put together some impressive combos. I'm curious how it runs in the 1/4...

Definitely nice numbers through the A4. Looks like the power was still climbing too!

damn good numbers through a automatic. Did you have trouble finding a piston for a 6.2 rod?

I am very interested to see as well, but I believe my stock rear end isn't looking forward to it. LOL

Thanks and no, Tony gave wiseco the specs and they made them with a pretty fast turn around I might add.

Thanks as well! I asked Pat on the first pull if it was locked and he said yes, So I assume the remaining pulls were.

Tony Mamo @ AFR

You can tell it was locked because it looks like a normal manual transmission torque and power curve....unlocked curves hide alot of the details with the converter slipping thru most of the run.

I was disappointed we didn't get to see a final run in third gear which would have been more representative of the true power we achieved here. I speculate it was closer to 420 RWTQ and 500 RWHP.

Whether you have a manual or an auto trans if you dyno in a gear that is lower than 1 to 1 you will always see a loss in torque and power (but a faster/shorter sweep on an inertia style dyno).

Even considering the second gear run though the numbers look great and the shape of the curve is excellent, especially for a fairly aggressively cammed combo. Note the shape of the dyno curve in third gear would have looked very similar....you would have just seen higher torque and power figures.

Regarding the rods, there were three reasons I spec'ed that length rod for Casey. The first was a longer rod made the compression height of the stock stroke piston closer to what I consider ideal (1.100 ish for me is ideal for a street/strip engine)....with the two benefits there being a lighter piston and slightly more dwell time at TDC....less rod angularity which is also bonus the more you turn it, and the best reason was I did have them collecting dust on my shelf from a former project I decided to sideline and was able to offer Casey a sweet deal on them....LOL

Casey....it was a loooooong road but the end results justify all the money and time invested. Look forward to some track times as well although Im not expecting much in the way of a good ET with the dead gear your running. This type of set-up is much better optimized with a 3.90 - 4.11 ring and pinion but when you do get to the track I have a hunch the trap speed will look great.....just make sure you shift at 7K ish.....and it might even like more RPM than that. Put that on my next dyno wish list as well....pull it past peak power to verify good valve control and allow us to calculate/optimize your shift points as well.



Cheers,
Tony

Strong numbers for sure Casey. Glad it all tuned in so nicely. I know it's been a long road getting all the parts together. It's nice when it all makes the power it should.

Thanks for including me in your project.

Tony, Thanks! It was a long road and a lot of time for sure, but your right that it did pay off and I am very pleased with the results. As for the gears, lol, my plans are a 9" since my stocker leaks like a toy submarine. I was hoping to have it for this build already, but it didn't work out that way for now...

Patrick, Thanks as well and especially glad I was able to have you to tune it!

No, but it made your car alittle more of a dyno queen, lol...

I forgot to ask the first time, do you plan on sending the heads to Tony in the future to get "Mamofied"?

BTW, great verse in your sig.

lol, I had a hiccup when building the car and the money had to go to it rather than a new rear...

I really wanted to have Tony do the heads thats for sure. But I was on an extremely tight budget with little room for error. I plan on having Tony do the heads sometime in the future, but have no idea when that will be.

Thanks about the verse, I like it too He is the reason for everything in my life!

Nice results!!
