Again, This was an early dyno run. The car is running in the low 11's on the AFR gauge now. The car has 72# injectors and the bosch racing fuel pump.

I will never use this dyno again, it's too confusing. I'll get it on the dynojet this weekend.

I don't know the build, but it is strange regardless.
Yes. Something wrong. By definition, hp/torque equal at 5250.

Just so you know, your numbers don't cross at 5250RPM...

Use 4th gear instead of reverse...it works better

I was talking to a guy at the track who had his son in Ca rebuild his Pcar trany. When he got it back it had 5 reverse gears and one forward.

You can just call him Mater. As in Toe-Mater without the toe.

(if you don't have kids under 10 you may not get it).

Wow. 408 whp at 15psi. That's pretty incredible. Means over 200whp NA. That must have taken a lot of work.

Which Bosch Racing fuel pump? It would be worth finding out the model and it's specs. You might not have enough pump/s for that setup.

Nice results!
I'm glad you got the AF ratio issue sorted out. What was causing the erratic AF readings on the dyno?

1 of those maybe ok on a modified 3L build but I'd be contemplating a 2nd one just in case.

1 044 is OK for gasoline but not for high power E85.

Yes, good point. I'm so used to everyone making the switch by now.
Going up to 3 of them soon enough.
