It should be about 525rwhp on our dyno. 575rwhp on a dynojet.

Think he meant 575rwhp on a Dynojet, per your previous posting. Motors always make make more power when the headers are pointing forward

Seriously though, nice numbers Jason!

If so it's possible on the right dyno. I made 560rwhp (Mustang dyno) with my car that has a Torquer cam, FAST manifold, ported heads, 12:1CR and E85. On a more generous dyno it could probably push close to 600.

How much HP over factory

Is factory motor on your dyno 525 nad like 490 due to stp factor? So basically picking up about 100 hp and 90 ft pounds of torque?

OE injectors?

Don't suppose you have a graph with the pull starting at 2000 do you?

Is this the 110 or 116 lsa torquer?

Can you clarify "high speed lifters"? I'm assuming they are short travel, light weight aftermarket?

thanks

videoThis is the car with the motor in it at VIR using 4th gear only all the way around the track no shifting.
Coming out of the oak tree your at about 2000 rpm and 43 mph at the end of the straight its 163 mph so the torque and power start low in the RPM. If video doesn't work go to ED7577 at youtube

Jason forgot to mention that the dyno they use has the Super Bee MF103 on upside down as their default intake for all dyno pulls.
