That's a 426 hemi. Lol completely different animal.

20lbs

25lbs

30lbs might be starting to flirt with danger a bit


I know guys putting 18-20lbs through a stock bottom end 5.3L on E-85 with no issues and they are running more timing than you would think. Depending on my final turbo selection and where the power falls I will probably need 18-20lbs to make the 1000whp target. Most of the time it will be on around 800whp which I should be able to get done with 14-15lbs.


You do realize that E-85 is 85% Ethanol right? 105ish octane with the cooling properties of methanol and it is cheaper than 93 oct unleaded.



See you don't know nearly as much as you think. There are guys on here that have never pulled a valve cover that know E-85 is great for high compression and boost.

guys holy shit loool

I have no idea about all the racing fuels But iv pulled a few valve covers lol

Lol computer controlled boost isn't the same. You are only pullin 20lbs at what? 5300? when you are about to shift? you make what before you get it spinnin? its like a VW it makes boost but it really doesn't Lol

What are you even talking about? Without having anything in the AMS-1000 ramping it should spool by 3000rpms and be making full boost by 3800-4000 give or take. Shift points is 6500rpm. Boost is boost. It's manifold pressure. Whether there is a wastegate spring or an electronic boost controller setting the amount doesn't make a difference.

I think you have exposed yourself.

Lmao. you exposed yourself long ago when you said you didnt need compression to make power then talked shit about your low compression motor with a turbo. Lol if you have boost control is obviously controls how much boost so you don't boost it too much at low rpms and fucking grenade your engine, but you knew that cuz you have built so many. right?

Man, like leave already.

How many times you gotta get schooled?

Lmao... do you even have a license yet kid?

get back on your huffy

Boost is a measure of restriction. 20lbs of boost at 3000rpm and 20lbs of boost at 6000rpm are completely different VOLUMES of air being moved and completely different amounts of power. Herp a derp.


A 1 point increase in compression is worth 1%-3%hp increase with all other things held equal. After 10 or 11:1 you DO get diminishing returns. You should let the cam specs and type of fuel determine what compression ratio you run, not the other way around. Dynamic compression ratio is far more important than static compression ratio.


You don't need compression to make power. Top fuel cars make 8,000-9,000hp on ~6.5:1 compression.



High boost at low RPM would mean you had a small enough turbo on there to spool it at that RPM. You wouldn't be making that much actual power. Great torque though. You don't know much about turbos do you? With a turbo big enough to make 1200bhp at 6500rpm on an engine like mine you can't make 20lbs at low RPM because the turbo would barely be spinning.


The extra volume from running E-85 and the bump in compression it allows DOES help the turbo spool faster though. If you built it with 8.5:1 like you probably want to the thing would be a fucking dog. Laggy as hell and miserable to drive.







And you said I was arrogant and had my chest puffed out... Lol.
