331 Laguna Dyno Results
 

About a month ago my father took the car to his school on "Dyno Day". Here's the results:

Here's a video of it that one of his students shot of it an her Honda (she mistakenly says the Miata made 250). Apparently the students like to have him sign their engines after he teaches them how to build them:

I was a little bummed as I was hoping to hit 300 rwhp and it only did 273. It did hit 311 foot pounds of torque which is not that bad.

Specs:
Forged 331 Scat bottom end with 10.75:1 compression
GT40 iron heads
Explorer intake/throttle/mass air meter
19 pound injectors
E303 cam

I'm pretty sure a set of AFR's would get me up above 300. If I could find a cheaper way though it would be nice.

Good HP !
 

275 rear wheel hp ain't bad hp at all.......equates to about 350 at the crank! Good Job !!!!

Thanks, I'm still fell short of that 300 rwhp horizon though...I guess the real important thing is how many Corvettes I pass with it on track day, right?

Sort of on the same note, I just scored a set of 24 pound injectors and a 80mm mass air meter from a MkVIII on Saturday ($60 bucks for everything). Hopefully they'll help a bit...

Should help
 

The improved air/fuel input should help with more HP. You've got a power to weight ratio of 9to1.....that's strong!!
