who has a 4.6 supercharged

[vashxj]

so has anyone in here run 8psi of boost on a 4.6 stroker with 9.6 cr. i was just building my 4.6 to run nitrous but i have come across a deal on the s/c unit i want. so im just thinking of building the whole thing

What supercharger? What's the plan?

I'm working on an MP90 for my 4.6L, but it won't be ready for another few months.

OP, Give me a buzz when you're ready....

it going to be a vortech v1 s-trim for a mustang but you have to tap the oil lines in the pan. i was thinking about forking a couple more bucks out for the self contained v3 but they are quieter, i like my friends mustang it really whines, also the v3 take its own special fluid. then im going to use a bigger mustang tb with 42lb injectors and the aem controller

42lb injectors may be a bit large

With a proper tune those injectors will be fine.

How much boost do you plan to have and how much additional power?

[vashxj]

Im going to run 8psi and it should be around 350hp and 400lb at the flywheel i tried to underrate all my math but this should be a close estimate. Those injectors will be 45lb on my fuel rail. My friend runs 65lb but his engine was built for 15psi of boost he is at 9.25 cr. I know i will probly have to run premium all the time and 110 at the track.

And silver what cr is your engine and are you getting your intake machined for a direct bolt up for the s/c? Mines going where the a/c compressor normally is.

Why run a piggyback when you can tune through the stock PCM?

can you program for 8 pounds of boost?, i didnt think that was possible with a stock pcm, the map doesnt see positive pressure... i could be wrong that was just my understanding

You would replace the stock map with a 2 bar one.

Its 9.5:1 SCR and 8.0:1 DCR. I need to CC the combustion chambers again to verify. Yes, I will me machining the intake manifold at an angle, welding a plate on and then bolting the SC on. Sounds a lot simpler than it is.

Well i realize i can replace the map but i didnt think the pcm would still be able to read right

[SilverXJ]

It needs to be reprogrammed to understand the 2 bar map
