So we did a back to back dyno test today on one of our faster all motor customers C6 Z06 - 2009. First three pulls with existing FAST 102mm Tony Mamo fully ported intake, swapped straight to MSD Atomic 102mm intake and made 3 pulls.
It was hot in the shop today in the 90's so hp was a little lower than past dynos but this was back to back within an hour with same coolant and oil temps on the vehicle, fully warmed to 180 deg oil temps before each pull with a dyno fan on it.
Vehicle:
2009 C6 Z06 - Factory LS7 stock shortblock - 9000 miles
FAST 102mm Intake manifold - fully ported by Tony Mamo.
Tony Mamo - max ported LS7 cylinder heads - approx 400 cfm on his flow bench - alot of time and $ in them.
Heads are milled and running cometic .040 head gasket - 12:1 compression ratio approx
Camshaft is a calspeed/btr - 246/254 .652"/.630" 111+2
Pfadt tri-y longtube headers, offroad x-pipe, factory C6Z06 catback
NW 102mm throttle body, Vararam intake
Johnson short travel lifters - moly pushrods, BTR trunions in stock rockers
Straight C85 race fuel in the tank - (Race gas version of E85)
Car has previously ran 10.1 @ 136 mph in 1500 DA weather at Famoso Raceway on a clutch going out and smaller camshaft. Just upgraded to new Exedy twin disc carbon to this camshaft and tested with both intakes. Expecting 9 second ET's with the extra approx 40 rwhp gain between cam and intake.
All work and upgrades performed by CalSpeed & Performance, in Bakersfield CA.
Calspeed and performance fully dyno tuned - 25 degrees timing 13.0:1 air fuel before and after (tune didnt change one bit between intake manifolds - air fuel didnt move - fully logged with wideband)
Dyno runs are in SAE and 3 pulls made with each intake and they were repeatable.
I appreciate any positive replies, every bit of information available is posted here and take it as you will for information on the results we found 1st hand.
