Thread: Supercharged p38

NICE Now if I had the money

Would.go.hard.

I remember something about an m51 charger being used.

It would go very hard indeed!

Those with supercharges, will also discover this. On most supercharged engines, Especially those using the Eaton M90), poor fuel distribution and weak mixtures eventually cause detonation that will collapse the ring grooves on the rear cylinders and cause partial engine seizure, and eventual piston breakage

You Can easily see, that this Supercharger (the M90) is far too small for the V8 Engine as it only covers three off the 8 cylinders, all others get varied pressure and flow that cause very poor combustion. The Air flow is not good at all, as and the Air filter is mounted in the corner of the engine bay is not only lacking an intercooler, it is picking up hot air from the exhaust manifolds too, the rooting of the system is also very poor As you can see the poor fuel distribution is causing the cylinders to run progressively weaker towards the back of the engine, Also you will notice the excessive un-burnt fuel sprayed from the extra injector is causing a high carbon build on the pistons after only a few thousand miles.
These are only a few off the problems with Supercharging this engine, unfortunately we are not able to show how the lack of ECU chipping will cause the demise of the engine and how it eventually goes into default mode after trying so hard to sort out what's going wrong, however I will have further written advice on this matter soon

Sounds like turbo is the way to go.

I'm sure it could be done right. Fueling, timing, etc. should all be changed.

I wouldn't be keen on running a very high boost though. But the torque would be awesome.

There was a comp rig a few years back with a twin turbo rover V8. Body I think was a toyota.

mmm, a good way to heat up the incoming air and get very little low down gains, and detonate an engine...all for $20k!

I have driven a few Supercharged 3.9 discos, I know they are no 4.6, but the bottom end torque wasn't anything to right home about. My N/A hi compression tweaked 4.6 would've eaten it off the line...and I was running 33's
