Guys could I run a rebuilt low comp LT1 with stock heads and cam, on an intercooled Vortech S trim at 450-500rwhp (Will probably shoot for 500 with a custom supercharger cam) using the stock PCM, but with a dyno tune by a good FI tuner, or would I need all kinds of aftermarket Fuel management stuff.

What kind of Fuel system upgrades are need for 500whp (thats all I want no more, but will probably start closer to 400whp)

Thanks guy

Stock PCM is more then capable.

with these guys, it will laugh at you. Not sure exactly the limit of the LT1's but the LS1 have no problem at 1000hp

uh... YES. The factory PCM from 99 and up will do it just fine. the 98's can't do 2 bar or 3 bar i believe for boost, that right? but to answer your question YES the PCM can EASILY do that

You guys REALLY need to read the post before you respond. Hes talking about an LT1 pcm, not an LS1.

As for the original topic, if you are going to have the motor and harness out anyway, upgrade to megasquirt. If you setup it up properly (using the Ford Edis8 setup), you will no longer need the opti. Just individual coil packs like an LS1. Plus you get a more boost friendly ecu.

Just something to look into. Just know that its NOT plug and play. Do some research first.

I read it just fine and the LT1 PCM is still more then capable. The Mega is very nice though.

The Megasquirt setup will run about the same as getting good tuning software in some cases. Not much money to be saved.

Well Im trying to get it done on a budget first so Ill stick with the stock PCM and when everythign is worked out, ill step up to stand alone setup.

Also what kind of injectors would I need for 500rwhp, this is through an M6 and 10 bolt.

I dont plan on going any higher at all and it is a supercharger so no boost spikes.

Also what kind of pumps, yall recommend?
In tank?

Not to sidetrack, but a 98 with boost is fine. Trust me.

Anything under 800rwhp the stock PCM will be fine and from what I understand the stock PCM will have better resolution...

I'm making 700 rwhp through an auto/loose converter and Ford 9", pulling 146 mph at full weight all using the stock ECM.

Same here... Low 9s with stock PCM
