Dyno results
Just got it tuned/dynoed with the new cam and existing ARE headers. It's an 06A6 w/ a 3200 converter. What would that translate to at the crank? I've heard different stories for drivetrain loss %
The first run was with a tune from a company that apparently didn't know what they were doing. The 2nd run was after the re-tune.

Seems about right, depending on your cam. I pulled about the same numbers with headers, a Fast 102, Comp XE-R 224/230 cam, a Yank 3200, UD pulley, and a tune. I think the torque converter lowers the numbers on the dyno a bit. Take it to the track!! that is the best test.

If car is making 420 rwhp a conservative estimate at the crank conidering a 20% driveline loss would put it at approximately 525 hp. dyno's can be manipulated to show the numbers you want to see but not saying this was done in your case. with your power and traction car would easily run deep into the 11's. like stated earlier track will give good indication of power car is making.do not be too concerned with dyno numbers.

I have the info at home, I'll dig it up.
525 at the crank? That means that a cam,headers and a tune got me 125 HP (assuming GM is right at 400 stock, which I'm pretty sure they are)......

Between 10%-20%, with varying factors is what I've heard. It also depends on the dyno he is using. My car was tested on a Mustang at HP Sales, which tend to be more stingy on the numbers. Dynojets will show higher numbers.
OP - concern yourself less with the dyno numbers and more with the performance. (the crank HP numbers are even less important). The dyno numbers are only used for 2 reasons.... 1. to say you have XXX HP, and 2. as a tuning tool. As I and others have said, take it to the track for a couple of runs and that will be the real test.

Its been a long standing belief that its a percentage because 430hp cars dyno 370-375. 1000hp engines dont lose 150 once checked on a chasis dyno. A Z06 at 505hp measures 450-455rwhp for most samples on my dyno.
Also, adding 20% to rwhp isnt the same as subtracting 20% from Flywheel HP. IE 420rwhp + 20% is 504hp, but 504-20% is 403rwhp.
This car making 420rwhp through a A6 trans is likely at 480-485 flywheel HP. Variables make it tough to measure such as locked/unlocked converter.

OP: Have you thought about installing a FAST intake manifold? Here is a thread that I made when I did mine - http://forums.corvetteforum.com/c6-t...st-intake.html
