Could your rpm be increased? Your power is still climbing at high rpm so why stop?

yeah des,i noticed it too,max rpm now 7200
but i use still hydraulic lifters and the crank with flywheel is not balanced so how for can you go with this?

[V6quattro]

I'm running 8000rpm on hydro lifters but my crank is balanced.

[quattro-nick]

maybe 7500 doable?

[diesel des]

Yea no problem. I was running up to 7800 on a stock bottom end engine no problem. For short blasts it ok but don't spend all day on the limiter.

Your Problem ist that you Need a Second intercooler for The supercharger, you Are pushing hot Air to The Engine so no power.

i dont have hot air problems!
i use aem W/M injection with one injector before throttlebody and this is active from 0.5-2.0 bar boost.
intake air temp on full load is max 30°c

How much above ambient is your intake temps mate when normal road driving ?

[quattro-nick]

i dont know
on normal driving the supercharger is disconnected
i will take a look on the next test driving with vems
how is your intake temp?

Around 9-12 above ambient normal 60mph B road driving
15-19 spanking it hard down the B roads

Have you tried spraying before the supercharger? Any thoughts on that? Should (based on reading stuff online, so no experience) improve the supercharger's efficiency...

a .82 turbine housing is also too small, getting too much backpressure.

What is the problem?
