Norbie, He tells me it revs to 11000 RPM, It's been bored out to 2380cc, the comp is 10:1 and it is built to suit forced induction. I was lead to beleive that one would lower the compression to apply forced induction and still have a steetable car?
Is that specific enough to not beleive everything he is telling me??
I'll hopefully speak to the builder later this week to find out more.

Crostek , What is the theory behind locating the throttle body on the intake of the blower??

Quoting from a previous thread on the subject:-

AFM = airflow meter.
But I think they measure this by how much the flap is open.
Now, pressure builds as soon as you have a restriction, so... at 1psi the AFM will be wide open, whearas in NA, this probably wouldn't happen until 6000rpm or so.

Soooo, if you can make the AFM stiffer, so that it only opens full at 7psi or so.... then you'll have some degree in variability of fuel in relation to boost.

----

Me again, My theory (let me know if there is a flaw in my plan)
would be to run the blower in front of the AFM therefore the AFM would be in the pressurized area but would still be reading the amount of air that passes to the cylinders. there would need to be some valves from one side of the AFM to the other to regulate the boost, but wouldn't this fool the stock ECU into thinking that it is N/A and not s/c if the supercharger was running from the vacuum hose and not controlled but the ECU (as in a 4agze)?
