Can you post some pictures?

Hi Richard,

yes, please have a look:

a precision 6266 is feeding a roots blower.

it was supercharged before with one intercooler.

now compound supercharged, two intercoolers.

turbo - intercooler - bov - throttle body - blower -intercooler - 2 x plenums (opposed aircooled engine).

1)i was thinking about one nozzle after the first intercooler before the throttle body to cool the blower rotors 50/50 mix meth / water.

2) or just spraying 100% meth 2 nozzles before each plenum. about 10 inch away from the intake valves.

no meth controller.

i may get some kind of heat soaking from the aircooled engine even with the interoolers.

i would like to run higher boost levels up to about 2 bar oder 30 psi.

compound boost usually kicks in instantly when you start hitting the throttle.

each unit runs about 50 to 50. if tjhe turbo has 1 bar, supercharger will multiply it to 2 bar for example.

european pump gas 102 octane will be used.

thanks

What target horse power are you looking for?

as much as i can. of course


just kidding.


fighting against higher iat`s and detonation that`s most important for me.


a 500 hp goal @ 1.5 bar would be a nice goal in my opinion.

more questions, what do you use to control fuel and ignition?

[34plus2]

i have a stand alone ecu (megasquirt ms2/v3). i probabely switch to a kms md35.

i currently use speed density and wasted spark with a msd coil pack. iat sensor is located after the second intercooler/chargecooler. no maf.

water injection can be also controlled by the ecu, but i would like to keep it as simple as possible for now.

It is an interesting project, thanks for sharing. I am not much help sorry on the subject.
