Slot maf for 650rwhp

[bg90coupe]

Let's try this a different way. What slot style maf would work for 650rwhp without an extender and would be mounted in a 4.25 Id or 110mm tube? It will be draw thru and roots blown also

I'm running VMP's 100mm MAF conversion. I assume I push 650+ rwhp on e85. Normally my MAF counts are in the mid 800's at 20 psi. I need to run a log now that its colder out and the car has been hitting 22psi.
