Injectors for Holley HP efi

[DButler]

I was wondering what a some good injectors to run with the holley hp efi setup sbc. I just purchased one and I am running a Victor E intake and rails. Right now I am running about 500 rwhp and hope to make 750 on next motor. I have a price of 350 from Rob at Force Injection. I am just trying to see if I should order from Holley or what? I am wanting 60lb I think?

I am running 50# injectors on my holley hp efi from RC injectors. http://www.rceng.com/ with my 383/f1 procharger @ 15psi. Runs like a champ! these are the 12-13ohm injectors.

It seems to be a really nice setup looking at it in the box haha looks to be well made.

Also does this HP setup come with a 1 or 2 bar map sensor setup?

[TraviZ28]

Mine came with 1 bar. I had to go purchase a GM 2 bar from the local auto parts store.

I called Holley and they said the 1 bar is good up to 14 psi. I thought 1 bar was only good for NA setups. I am now sat 10-12 psi but on new engine I can switch to 2 bar. Do you have a part number and price by any chance?

1 bar is good for 14 psi however you need to accommodate for elevation and rule of thumb is to subtract sea level pressure (14.7) so yes a 1 bar is good for vacuum to 0 pressure (sea level). You need a 2 bar. Grand nationals used GM 2 bar map sensors, BWD part # EC6001

For future search's the GM 3 bar map sensor off a 89 TTA (turbo trans am) is BWD EC1678
