618 RWHP LS7 Dyno testing Sat. Well the car previously made 608rwhp but I tested a Kooks 3" axle back and Haltech CAI today.
BEI 438ci LS7 Wet Sump
4.125 Bore 4.100 stroke
Sleeved L33 block
13.7:1 compression
Ported BEI LS7 heads
Ported BEI MSD intake
BEI Custom cam with only 12* overlap-mild driver cruises great at 1600rpm in 6th. I routinely shift every gear at 2k rpm for normal driving.
Bushed rocker trunion upgrade
3/8 pushrods
BEI dual springs with ti retainers
Delwest TI intake valves and hollow steam exhaust.
2" Kooks and Kooks 3" x-pipe
Kooks 3" axle back
E85 or walk home.
Going from the stock Ti exhaust with bypass mod to the Kooks 3" axle back netted 0 hp. Which I had suspensions that it would be a net zero gain. More surprisingly though it is much quieter the Ti exhaust. BTW I have a modded Ti exhaust for sale haha.
The Haltech CAI picked up 10hp over the C5 style Airraid intake.

Yes it is a small cam 238-246 115. It was a compromise but I drive it every day, and keeping piece in the neighborhood is good. I am really happy with the power and how nice it drives. It would be an animal with the right cam but would be a drag to drive around at low speeds.
