There is no E85 available in out pumps, that is 93 oct with 10% Ethanol and water/meth injection.
And yes we do, my NA car has 160 HP is running at 13.3 AFR.

Thanks for the info. You've got to be pretty close to the Walbro's limit. A 67mm throttle body is good for 700-800whp. I'm sure the 90mm makes it hard to drive at low throttle.
As I've suspected before:
This proves that you don't need a $1500 built head to make 500whp!!!
However, I'm still installing a set of $80 valve springs in case of valve float.

Ohh wait, I forgot!
I do have OEm 4G63 valve springs, they measure about 12 lb more on our heads. if you don't trust then go with aftermarket, Crower are about $90.
Engendro has only Ferrea valve springs and retainers, video for reference.

That's exactly what I bought. 4g63 springs from Crower. Paid $83.58 shipped.
The bigger question is what is he using for a transmission?

I has a 4 puck solid center ACT clutch and a custom made twin diaphragm pressure plate made of two Exedy Daikin.
Have in mine that I have a X3 tranny and that it is push not pull. The car does not have good tires and it there is no traction there is no clutch slip.
