Then again (as reminded from another topic) you could have restriction on the other end if the intake bellows is collapsing..did your dyno guy mount and AFR to the exh pipe to see how rich it was running?

I didn't see the air intake collapse, but was not paying close attention to it. It was running rich, he guessed I could gain 10 or so hp by leaning it out. Marcs chip will take care of that.

Dyno'ed again yesterday. Since the last time, I've done ceramic coated OBX headers, OBX exhaust, a Marc chip and Marc's intake hoops.

The last run in March netted 311 SAE adjusted wheel hp. It was a perfect spring day, and the actual number was 325 hp. SAE adjusted me down to 311.

Yesterday was a perfectly horrible day. Too hot, too humid, pressure too low. I was hoping for 340 rwhp. SAE adjusted was........353 rwhp.

Awesome - 353 at the wheels must feel good.

Steve, how was the AFR on the dyno run? Did Marc's chip keep things in range with your mods?

ghlkal, the afr looks to be about 12.5, a little leaner than it was on the first run. That's what Marc wanted because I have no cats.

Dave, the permagrin is always big. It must be better in the drivers seat than the passengers seat. After a bit my wifes small grin turns into more of a frown. As if to say, "do you always have to mash the pedal to the floor?". -Steve
