this is my heads and cam Z06. only changes where m6/3.90s to A4/circle D 4+c stall/3.42s (car now has 3.73s). sorry for the shitty pics.

 

cant read the second graph to tell whats going on lol

 

fixxed

 

different dyno?

 

I would expect to see about a 30 hp or so drop from a m6 to a a4 with a locked converter. That would be on the same dyno ofcourse. So it looks to be in the right ball park. If the converter was unlocked you could end up seeing a loss 0f 50hp or more easily. Anyway it should fly at the track with the auto. HAve fun with it.

 

Is the second one both M6 and A4? Can you give me the Cliff Notes on what the results were?

I sometimes use the Dyno numbers I see posted to figure things out. I know when I see an M6 making real good numbers I do a subtraction. So when someone puts up great A4 numbers add some to it!

 

the second graph is A4 only. i don't know what the lines at the bottom are.

 

thanks i'm really looking forward to it. track launches should be fun with the trans brake.

 

Okay I think I got it.



M6: 442/406

A4: 405/390


I have the same converter and similar numbers (400/380) but I am 9" (add another 10 HP).

So if I had an M6 my dyno numbers would look like eye candy.

 

my mods are:

halltech stinger filter

i was going to put a fast on but since im going fi next year i decided it wasnt worth the coin. how is the circle d around town?

 

I love the converter. Best mod so far and driving is great around town. The 3.70's though make highway a little tough.


To be honest I don't think the FAST was really worth it over the LS6 intake.


I never imagined being and auto you lose like 30 HP on a dyno.
