Hey Looks good, can ya explain your set-up ?

Looks like individual coil packs on the front?

What's the aluminum deal/airbox above you intake manifold, with the end caps you would almost think ya had rotors in there?

How much horsepower are ya making?

Thanks for the picture and your time, look forward to more pictures.

guessing its Electromotive FI with PFM intercoolers / turbo stuff.

Lake water intercoolers up top. Made them myself from 1/2 Alum plate rolled bent and machined. Not casted, Two pop offs valves in front with trams coolers inside to cool charge. Electromotive tec II engine control. Turbos are TO4s from john deere engines. Machined exuast and intake housing for different impellers myself on Cincinnati CNCs. Looked into PFM stuff but was insanely priced in 1993. Machined pulleys bent and weled alum tubes water cooled turbos here at my shop no problem at all. Hard part was leaning to tune motors with laptop. Even made the water cooled exuast pipes and tips.

Very nice,.............how much air temp do you drop by the time it exits your intercoolers ?

Havent had the laptop hook to motors in about six years. Best I recall the air temp is about 120 Deg at air doors where carb would sit. At about 14 PSI. Never checked at turbo outlet. Temp changed from sprig to summer as water temp changed.
