Default Dynoed AFR Heads VRX2 Ported Fast 92mm

Wanted to try a mix match setup.. Mods in Sig, plus using Pacesetter 1 3/4 headers, steel flywheel and high flow carsound cats that are 3 yrs old. 85 degrees and 95% humidity. I know yes with kooks or QTP headers and/or an open cutout and a LW flywheel and 85mm MAF it will be more. Although I am using a ported smooth out stock maf.
Of course I wanna thank vengence racing and AFR for there products but wanna give a special thanks to RevXtreme in Fla for Helping me with my build. Thanks again Tracy and Matt.
Would also like to add that this car runs like a raped ape past 3500 rpms.

Looks like a little tweak in the WOT fuel tables from 4800-5500 is all that is needed. And it is still pulling above 6K...run it up to 6400 and see where it drops off.

Nice looking setup. Don't waste the money on the bigger MAF. Instead, have the cats cut off (almost free mod) and spend some money on the exhaust. PM me if you want the name of a good exhaust guy in WPB.

Looks good. What are the VRX2 specs? Also how much timing are you running? Stock GM headgasket or a thinner cometic?

That's a lot of dough spent for 427rwhp but the TQ curve is beautiful.

Yea it is a M6. How much more power would I get if I massaged the runners and a bigger cam in the 230's

Are you running an UD pulley? I don't think the numbers are horrible as I have seen similar setups pull different numbers on different dyno's. If I remember correctly, you previously had a different cam/rocker setup and then made this change. What were the changes and can you show one dyno vs. the new setup?

So the changes were new cam of slightly more duration, drop from Crane 1.8 to YT 1.7 rockers and a FAST for the new setup?

I would talk to Tony Mamo but I think you need to look at the exhaust side of the setup. See what Tony thinks. I think the cam it performing good because of the nice flat curve you have and it certainly carries well to the higher RPM.

Hi Yes that is correct ^ vette nuts you mean then to go catless and maybe use a cutout. I know I would probably pick up more right?
