Nice numbers

What are the AF ratios like?

You got some balls running a 17+3 combo

I'm sorry, I was wrong on specs. It was running on 14psi with OEM SC Pulley.
AFratio was around 12.8-14 on full throttle on 14psi. I don't know maybe it would be better on lean on 18psi.

Peak EGT is 810-820 Celcius Degrees end side of the Header w/out Meth.

nice numbers I think it is M7 Cosworth head, am I right?

[grkm]

It just modificated oem JCW head , you know its not so good for our cars, causes high temp. on pistons , constrains air flow etc etc...

I think now it's as good as RMW's or Cosworth's head, you see the power band and figures on stock boost.

running on 15psi
