Is that a off the shelf grind?

 

Pat-G, Would you recommend something different?

 

A4 with Yank Pro-Thruster drag converter before I went big cubes was making 440/427 on the 347 motor on a VERY conservative DynaJet.

 

Personally, I hate seeing 25-30 rwhp left on the table by not running a Mamo ported FAST 90 or 92. There are no drivability downsides and only power to gain. My 444 rwhp guy running the LS6 intake would have been in the 470+ rwhp range with the ported FAST 90. I also have some newer cam grinds that I like for making more power, but honestly, the 224/228 .581/.588" 114 LSA AFR cam is very easy to tune and makes a beautiful power curve.

This is kinda of what I was getting at. Thinking that the AFR 6016 is about 4 years old, And maybe things have advaced a bit.

 

That combo will always pull nice and hard through the entire RPM range.

 

eamador11, You are a perfect example of my post/research. You are at 440RWHP and have all of the right stuff. I am sure that it is a great combo. I have found that most of the guys running this combo make about 440-450 RWHP, and that is great! But if Tony is making 481RWHP. I want at least 470-475RWHP. Where is the other 40 HP?

 

See post 18 and 24 for the missing power.

I'm waiting for my AFR 205's now. Already installed a 228/232 112 cam, Have the Mamo ported Fast 90. Going to 11.3 compression. The rest is in signature.

 

Yes I did see that. I should have said that Tony and Pat-G can make 480RWHP. You are the only two I have found making that much with that combo. The rest are still 440-450 with the fast?

 

What about ported AFR 205's, Ported Fast 92/92 setup, 228/232 .612".600" 111* LSA and all bolt ons minus ewp? What would your guess be on a 346ci?

 

Anyone in that power range either did not have all the key components necessary from "the Mamo recipe" (like 11.5:1+ SCR, tight quench, headers with HVMCs, badass exhaust, YT rockers, Mamo ported FAST, larger than stock MAF, large airbridge and oversized air box, electric water pump, and a razor sharp tune) or they're on a dyno that spits out lower than average numbers (it happens). The nickels and dimes add up, they're just very expensive. Most people skip the squirrel mods and keep the extra couple of grand and call it good.

 

B-I-N-G-O

Read most of my older posts....I normally quoted 475 RWHP because thats the number it would spit out time and time again (saw 480+ a half dozen times....475 about three dozen times).

The devil is in the details right down to the weight of your clutch/flywheel as well (and the weight of your tire/rim combo). An LS7 clutch in my car would cost me close to 15 RWHP....NO other changes....heavy repro C6 rims and tires....there goes another 5-7 RWHP, etc., etc.

How many of the guys out there invested 100's of dyno pulls and parts swapping continually refining their tune? Take anybodies current average tune situation and add about 50 more dyno runs trying different parameters and see if you cant find at least five more....some of you could find ten. A shop would go out of business trying to do that for the average Joe.

The numbers are real (six different dyno's in two different States) but unless you copy my car to the letter and invest a bunch of time in optimizing the tune I assure you that you will fall short and I never made any bones about it back in the day when this combo was more of a hotly debated topic.

I did help a particular customer copy my package to the letter BUT, it was thru an A4 with a higher stall converter. With a typical three hour tune he ended up putting down 440 RWHP thru the auto trans.....easily 470+ with an M6 and maybe more depending on how tight the converter was (3600 stall btw). This combo IMO, very much validated the ability to reproduce my numbers if you invested enough time and money to do so.

Hope this helps....

I planned my setup with Tony keeping many of Patrick's suggestions in mind. AFR 205's
11.3 SCR, 8.7 DCR,.035 quench, YT rockers, SD tune(mafless), sealed and insulated airbox with 2 sources of fresh air, no cats,2.5 duals with x-pipe, UD Pulley, Mamo Fast 90. I'll post results when done.

 

Mine is not the exact mamo setup. Heres what im missing:

-LG Pro Long Tubes No cats (i believe it was no cats I forget)
-EWP water pump
-My heads should have been milled to .024 or more. I only did .020 because I didnt know any better at the time. Im still kicking myself for not milling down to 62cc.
-adj roller rockers
-days of tuning for max effort aggressive tune. mine is conservative coz I cant afford to go over the top
-im sure there are others that i cant think of

As stated earlier, money is what will limit people. 4 yrs ago, my budget was $7500 installed. I already broke that budget even without the parts mentioned above. I will tell you what though, numbers do not tell it all, if you drive my car yourself you will see what I mean. Its all about combination and letting each part work together. Focus on the right parts, dont sweat the numbers.
the mamo combo will pull hard no matter what parts your missing.

 

Yes Tony this does help. I am starting to see light!!! LOL

 

Clutch/flywheel plays a role. There is a dyno out there where they removed a stock LS6 clutch and installed a light Fidanza setup with no other changes. There was a considerable increase in hp on the dyno.

 

Corvettes seem to dyno higher maybe due to less power loss through the drivetrain or weight?

 

Pat, would you care to expand on your quote?
