Those numbers seem sorta low, but that stock catback might be giving up a few horsies.. You should take it to the track..

Insomniak: You bastard.. nice z06 Thats my next move also.. once the turbo kit is done on the z28, I'm driving it a bit.. selling it, and getting a ****** z06.

Peace,

The driveability is just like stock except for the clutch portion, but that is the nature of the clutch. I drove back from Houston about 210 miles and really hammered it alot along the way and got 20mpg. The other day went to austin and drove like a normal person and got 23.4 that is up and down hills in the hill country. Overall the gas mileage is about the same on highway maybe 1mpg better. I usually get about 21.5 going to Austin. The thing really feels punchy no matter what RPM and pulls hard all the way to redline at 6700. I really like this setup and is great.

whats the difference between your setup and the setup that tony made 480rwhp with? i think the heads and the cam are the same as what he used.

BIG G

Distortion69, I was hoping to see higher numbers also since Tony Moma posted all those great 450rwhp numbers but this is what I get and MTI felt it is about right and suggested the 3" exhaust too. I may pickup 10hp if I go with the exhaust not sure. Anyway the numbers are definitely not where his wer, and I didn't expect to get there either. I just did it to see what we would really get out of his H/C combo and now we no. There were no dyno tricks or anything and this is what can be expected. Now on another not my uncorrected numbers were 438/404 so maybe Tony was listing uncorrected numbers hummm.

BIG G

The dif in my setup and Tony's is he had a 78mm fast intake and tb and got 450rwhp then switched to the 90mm and pulled the 480hp. I also chose 4 degrees advance and he used 1 degree.

Big G: i think you have to do the same ratio rockers that AFR did and the eletric water pump to squeeze that extra power out of it.

if i remember right AFR has the same cam you do but they have the lift adjusted to where its about like a g5x3 cam over 600 lift

BIG G

Insomniak I forgot about the EWP but that will only ad about 5rwhp at most I will look back at the rockers and see what tony had. If I add the EWP and get 5hp then 90mm and get 20 hp that still is only 443rwhp and lets say my exhaust is 10hp thats at 453rwhp. Now this is all to the max effort and would still be 30rwhp shy of his numbers. I think maybe his dyno reads a little high and with the MTI TB I already gained 5-10 rwhp of the 20 rwhp form the 90mm so that would put us back at 443 448rwhp. I dont know.

BIG G

I do like the setup though so don't take any of this as I am disappointed. I just wanted to see what I would get compared to his results. You just don't see too many big hp numbers from a cam this size. I read all the garbage from ls1tech, com , corvette forum, z06corvette forum , ls1gto forum and all the results varied. I feel my numbers are what is realistic and can be expected. I will probably in the future do the 3" exhaust and may go 90mm tb setup and then I will see just how close I get to his results. This is a great product and by no mens nothing to sneaze at. It is punchy all over from low to high and really kicks your butt about 3500 up.

Exhaust 10RW,90LSX/90TB 10RW,EWP 5RW.
418 + 25 = 443 not bad for a mild setup....

BIG G

JS what wer your results and setup on your car. I would like to see the dif in mine.

Mirek

"Ultra-pissed" would describe my reaction to those numbers on a dyno-jet after all that cash and work. 418 is easily attainable on stock heads. Your running 11:1 and have longtubes too ?!?! Wait and your "tuned" ??

i think tony has 1.8 rockers.. make sure though u'll have to measure Piston to valve clearnce but thats their llil secret to getting that much out of a 224 cam.. just my opinion.

BIG G

Why be pissed the average for this size cam is 410-430rwhp. The big numbers are just freaks or a dyno trick by some shops and all that money is not much. I got a package deal from MTI all at once so it was good. The car does drive like stock except when your right foot gets heavy. Now if I really wanted power I could have went o 230 up cam and then it would not drive like stock. I want to see one of the larger cams drive in 6th gear at 1000rpm's like I can with no surging or bucking. I don't think that could happen. I will go to the track when I can and then that will be the true test of this setup. Dyno's don't mean squat but ET's and Trap speed that tells the truth.

Mirek

I thought Mamo had stock rockers.
I also agree with everything you said, but the dyno is a tool. With a tuned engine, with a "matched" medium/large cam, long tube headers & AFR 205 heads milled for the compression....WTF.
I assume you have an LS6 intake...there is not much left but more cam and flycut pistons.....unless you go to 225's and gear.

What was your baseline?

BIG G

Baseline was 309rwhp/330rwtq. Heck I may be losing way more to my exhaust than I think who knows. I think what I got was realistic to what most will see. MTI doesn't try to bloat there numbers and set their dyno up so you know what you are getting.

Dyno dont mean ****, He has independent rear and I beleive they soak up a little. 400+ is nothing to sneaze at. I ran 11.60 with the same cam you run with only 400 rwhp in a 3726 lb car

The 480+ numbers come from cars with big (G5X3) cams, FAST 90mm setups, good headers, Z06 or 3" exhaust.

The numbers listed on AFRs site (530/475tq at the flywheel) are with the following combo:

All Same As Above With The Exception Of: AFR LS-1 "205" CNC Heads, Fast
Intake Manifold, Cam-224/228 @.050 .581 Lift, 78mm Ported Throttle Body.

However, this same dyno measured 428/432tq with a stock, LS6 intake, long tube header, 3" exhaust

Take the 15% out for driveline losses and the AFR setup makes 455 rwhp, while the non AFR setup makes 366hp at the wheels. I don't think the 78mm FAST setup makes much (5hp?) over an LS6/ported TB. I'd say the stock exhaust isn't helping you, ditch that and then you'll be in a much better spot to compare #'s.

But, it is really hard (meaning useless) to compare #'s from different dynos/days/etc. Take it to a track, get some times, and then compare.

My car has never been on a dyno...
I could care less,it runs the number
