For a 408 I would go with an F-1A as it won't have to work as hard as a D-1SC on your 408. Take a look at the dyno chart at the link here. http://shop.brutespeed.com/Brute-Spe...d-Camshaft.htm
This was on an LS2/402 with AFR 225 heads, FAST 92 intake and the F-1A at 12.4 psi. I don't see you having a problem making similar power with your combination on E85. Bob

Thats a lot of power so how much boost would u recommend to start out with for its first tune?

Bob@BruteSpeed

iTrader: (16)

Provided you have a good fuel system I'd go for 10 psi. Bob

Ive heard that when running e85 u need a crazy fuel system. Ive heard that guys run 90lbs injectors and twin pumps. I currently have 55lbs injectors so i take it ill need to build a fuel system?

E85 takes roughly 30% more fueling then pump or pump/meth. It's good to have to much fuel then not enough

Sinister_Z28

Makes sense so would u guys recomend meth if i go with 100 octane cause i found a place like two miles from my house that sells 100 octane from a pump 24 hours a day. Im just trying to figure out all my options.

SKULL

You don't need 100 unless you're looking for max numbers. And that be so expensive. Around me it's 7.70 a gallon for 100. Just do a 93/meth tune or do a e85 tune.

Sinister_Z28

Ive seen some guys here in socal do 91 with meth cause 93 is damn near impossible to find. Would that work or is that to low of a octane.

Bob@BruteSpeed

You might get by with 91 octane fuel and 100% methanol. You can always mix in a couple gallons of 100 octane if you need to. Bob

So if i decide to stay with gas will my 55lbs injectors work? What fuel pump would u guys suggest?

Bob@BruteSpeed

iTrader: (16)

No, you're going to need at least 80lb injectors, depending on how much boost you end up running.

You are going to need to replace the complete fuel system. We used an Aeromotive Eliminator fuel pump on my Camaro along with -10 fuel lines. You are going to want to use Teflon lines as today's fuel leeches out through standard braided lines, and will stink up a garage. Bob

Sinister_Z28

Thanks for all the good info Bob. Now where would i buy teflon lines and where do u run these ten lines two? Id assume it would be 5 lines to the regulator and 5 return lines?

Yeah your going to need a pretty decent fuel system. PLAN FOR THE FUTURE.!

The E85 is a pretty good source of insurance. I am personally going to run the VP M1 100% methanol on the highest setting from dual nozzles on top of the E85 for even more safety and for a little extra power whily trying not going to get greedy.

The idea is longevity.


For example on my build

390ci
E85 with 100% M1
F1A--- Hoping for 15-18 lbs overspinning by 2000rpm

Fuel System:

Custom Made Twin 340 Lonnies Pumps (actual 340's not the part #)
Stainless Braided Lines
Fast Rails
-6 Micron Fiberglass Fuel Lab Filter (e85 rated)
Fuel Lab Regulator
FIC 192lb Injectors @ 43psi


They injectors are a little over kill, but I am tired of constantly having to get new ones for more power. 127's may get you there on 10 lbs but it cant cost too much to step up to the 160's. Once you feel 10lbs of boost your going to want more soon after.

Hopefully this gives you an idea of what you may eventually need. You can also try a magnafuel 750 to save a few bucks.

You're welcome. I am referring to one -10 line running forward supplying fuel and one -10 return line. Lonnie's can supply you with the teflon lines and fuel system. Thanks. Bob

Ok guys now that i have an idea on what i need as far as fuel system and which procharger to run i am wondering if a 9"rear end on sticky tires will live if i do go forced induction? Also does anyone know about how much of a difference there is between rear wheel hp and hp at the crank? And thank u Bob for the clarification on fuel line sizes.

I8UR4RD

iTrader: (16)

9 inch is what youd need. should be good to go if its setup right as far as pinon angle and lash and all that BS i have not on clue about personally.


as far as crank hp and rwhp depends on the drivetrain. some say 15% some say 18% blah blah blah.

only number that matters is mph and ET and 60 foot.

personally had a car I know of making 624 at the wheels running 5.70's in the 1/8

Sinister_Z28

Thank u so much guys. Ive learned alot and i now know that i have a lot of work to do before i can get the procharger. Ill pm u guys if i can think of any more questions. Thanks

A 9 inch with a Wavetrac is what I would go with, check out the above link. You're welcome, thanks. Bob
