i have a stock block, 2.8 KBH on the car now, going into a moderate summer build. My question is, what boost level is needed to break 800RWHP with this 2.8KB. Keep in mind I know it needs E85, it is basically a FBO vehicle. TIA.
You will most likely need at least 25 PSI.
maybe. My car with a 2.8 KB non H makes 720 on 24psi with E85.Probably not even that much. The E85 is going to give that motor a nice kick.

Don't the H and the L have slightly different boost output levels
Ill double check but last time i looked up the serial number it said non H.You sure it's non-H? All 2.8L except for a few of the first off the line are Hs. Did not think any of the non-Hs went to the public. The 2.6L you could.
yes
I’m doing FBO, fuel system, untouched block. It’s a standard inlet, both numbersI ran a 2.8L for years. What car is this on? What do you consider moderate build? Do you want SAE numbers or STD? Which 2.8L you have? Standard inlet or Mammoth or Behemoth?

I have a buddy who is running same blower, but his MAF tapped out an had a boost leak, at 24psi he made 760, but his boost leak dropped him to 22psi he saidYou will most likely need at least 25 PSI.
What setup are you running?the e85 or higher octane mix will more than likely get you to 800. I'm going to be trying that Ignite 114 on my setup.

I would say so, just need head studs to support the boost

You are going to have to look between 24-26psi. With just bolt-ons I doubt you will hit it SAE but you find a friendly dyno and you may be able to hit it STD. At those boost levels a Behemoth/Mammoth inlet will go a long long way. I have seen heads/cams/heavy boost 2.8L/2.9L not break 800rwhp a number of times.
To be completely honest, I really don't care about dyno numbers. I want the results on the track.
Should be well into the 9s... As long as you have driver mod haha
Ill definitely shoot for the moon lol i like dyno numbers an track times. I also have a crew of cobra owners an i’m coming for the crown but three of them are in the 8’sYou are going to have to look between 24-26psi.
