What the hell. Now I need to change mine up again haha.

Nice job, once i finish tuning we'll have to compare.

One question though, why do you have the supercharger coming on at 4k rpm? The entire reason i made mine was so i could build boost at 2k rpm

NV

looks like its not compound. diverter varies intake between turbo and the eaton. sc up to 4k then switch to turbo? wonder how the shift feels?

second look maybe it is compound and the eaton blows through the turbo till 4k then turbo draws its own air? wtb more pics please.

supercharger coming on depending throttle position. If throttle position is over 20% supercharger coming on.
supercharger coming off over 4000rpm. No more heat and power lose high rpm.

Piping. supercharger filtter -> volvo penta non return valve -> turbocharger -> cooler -> throttle pody
turbocharger have own filter before volvo penta 3-way valve.

Supercharger rpm is fit engine rpm engine 1500-4000rpm Supercharger boost 9psi. When turbocharger flow more than supercharger volvo penta non return valve opened and relay control Supercharger off.

I'm not very knowledgeable on the M62 but I do know there are people who "port" their M112s for cobras. Basically it involves enlarging the Triangle output on the bottom lengthwise. This supposedly allows you to have a higher rate of flow through the blower. However there is the possibility that the actual pulses from the blower rotors will be more dramatic. as far as I can tell nobody has down real scientific research on the subject.

Do it. If you've deleted the ac and power steering, it should be easy enough to run a vortec, paxton, rotrex, or whatever easily enough with a custom bracket.
