If I install an after market fuel injection system on my 400+ HP SB Chevy Desktop Dino says it will kill my Power? :nonod: Why is that and do you guys know if it is true? I am looking at a Holley system.

Did you run it using the 1000 cfm, on a sb delivering that much hp you need to upgrade from the base unit. I am sure that more will chime in soom.

What cfm are you using for each manifold type?

Also, be careful not to use the TPI manifold selection, unless you are actuallu using a stock TPI manifold. If you're using somehting like a Stealthram, SuperRam, Miniram, or converted single plane, then TPI is not the appropriate selection.

Your power and hp should be roughly the same with both EFI and carb induction systems assuming the manifold types are the same and the cfm are appropriate (a TPI manifold is more restrictive than a typical single plane for insance). However, the EFI engine should produce better overall, or average torque under the curve, than a carb'd engine though, assuming the fuel and ignition maps are good.

I am looking at the 900 CFM TBI unit. :steering:

IMO I'd plug in 900cfm with single plane then if that's the type of manifold that comes with it :yesnod: .

I'm looking to install the new Holley Stealthram in the spring, so I'm using the tunnel ram intake on DD ;) .

After spending 1 hour with turbovette the Sat. I would definately ask him for some advice. He has put a Grand National trubo 6 cyl in his vette and is in the mid 9's with his modded EFI.
