Been searching around ALOT about this sort of thing, cant find much, even holley's website days little / nothing about it.

Currently have carbed 355 chevy, roughly 420 at the flywheel @ 6K without the blower, was making 520 HP at the flywheel with the blower. Sold the blower...

<b>want fuel injection! sick of bad gas mileage from carbs. </b>

Question is, will I make the numbers im making now with a holley stealth ram and their Commander 950 ECM?
And a future upgrade includes an ATI procharger system for a TPI thirdgen, will this FIT my stealthram? Not to mention, will the Stealthram be a bottleneck for the supercharger? Figure 550-650 Horses.

My main goal is to increase reliability / Gas mileage by doing this, so If my HP number take a little hit, so be it... But is it worth it?

Im on the phone with THUNDERRACING right now, he does not sell the commander 950 ECM with his stealthram setups, just the intake itself, but he is helping me out alot by pointing me in the right direction, and helping me do research. I may buy the ECM from holley and the stealthram from him if all goes well in fact.

 

The HSR is based off of a holley tunnel ram so its safe to assume your numbers should be fairly close, I'd take a stab and say they might be just a tad down since carbs make nice peak hp numbers. Dont expect better reliabilty though because thats a long shot. There's nothing to a carb to break, its based on the simplist principles of mechanics and vacuum. EFI is sensor after sensor after sensor, miles of wire, and an ecm (165/730) that is about as impressive to motorsports as windows 3.1 is to all the computer geeks out there. And this is all coming from an EFI fan


You will however without a doubt enjoy the increase in fuel milage, tunability, and driveability, the latter two being hard to quantify but universally agreed apon.

 

Jeg's lists the Stealth Ram complete with the 950 ECU, polished finish for $2300 or so. It's in their newest catalog. I bought just the 950 ECU & harness from Summit for around $800.

 

yeah $$$$ stuff. I was thinking of junkyarding a TPI computer/sensors and buying the holley SR intake and some injectors then burning a PROM for it all... That would probably cut the price in half or better, but i guess the tunability of the Commander is 10X easier since you can do it on-the-fly with a laptop. I dont know the first thing about burning proms anyways sooo... I think... Ill just blow the money on a blower instead. Or a tranny. any good 6 speeds out there for like $1200?
