439.7 HP /399.0 TQ This is our best to date with a H/C car.
We have been trying a few new things with our RGR heads and it is working
02'SOM SS M6
RGR S2 5.7 HEADS
224 581 112
PORTED TB
STOCK MAF
ASP CRANK PULLEY
HOOKER LT'S/ORY
LOUDMOUTH W/BOLRA XR1 MUFFLER
10 BOLT W/4.10 & 315'S
439.7 RWHP 6350 RPM
399.0 RWTQ 4600 RPM
NOTE:for those who are skeptical about a pulley the asp crank pulley picked up 8rwhp and 6rwtq

Re: 439.7 HP /399.0 TQ It is a bit on the lean side, but the car only has 24* of timing with no knock retard. When our tuner gets back from vacation next week, we will richen it up a bit. It may make a few more or a few less HP.
A4 cars generally make about 20-25 less HP.
We have done some G5X2 cams in A4's, but not with these heads.
The pulley was worth 8RWHP in this car.

Re: 439.7 HP /399.0 TQ
nice M6 numbers, but what kind of numbers are you getting with A4's? Have you done any G5x2 cams in A4's yet?

Re: 439.7 HP /399.0 TQ Nice numbers! 
I just put a FTRA and ASP pulley on my pretty much stock '99 this weekend. I'd been trying to resist modifying the car (it's my grocery getter), but the temptation is too much. Anyway, no dyno pulls but the two mods together made a clear SOTP difference, and I consider myself a little hard to impress. I believe the claims by various people that they picked up 6-8 RWHP with the pulley.
Oh, and NO difference in alternator output. At least as measured by our "accurate" GM gauges. This is in an M6 car, an A4 may show a difference.
