That upper intake is sweet. I never understood why anyone would gut and rotate a stock upper when they could make something like that.

What are you doing for management right now? Blow-through VAM?

CspecRun

Welcome. I love those cars. What kind of times/power is that car running/making?

Nice, hard to find any more of those merkurs around. Thats a good motor to work with.

It is really hacked, blow through vam(the small one) and a rising rate fmu. With a wideband i was able to get 12.5 afr @ 17psi

I dont go off roading with my xr, and i have a filter,its great at collecting dust in my garage. The filter i found that fits over my turbo is too restrictive, it kills my spool time.

FMU on a turboford! Whatever works, man!

(I don't use a filter, either. )

Damn 12.5 is a little lean for 17psi man, good thing
those motors are stout as ----
