what fuel/air for low 12's?

[gl4787]

What kind of fuel and air do I need to run low 12's - high 11's? My boss has a fox body that may run around there and I just want to know what it takes to get there. Plan on having Exergy do my injectors, but don't know how big to go. Also, will any of the stock appearing units get me there? Are they worth it? Or would it be more cost effective to go with something different? Any help would be appreciated. -Garrett

I run 30% injectors, dual pumps and an s472 turbo...full weigh crew cab...got me [email protected]

Better have some low mile rods :roflmao:

But an S366 should be enough air, stock injectors might do it I'm not sure. If you do nozzles, might as well do at least 40% over. Plan on shedding weight, and work on launching that pig.

The stock appearing IHI turbos will supply enough air, but cost wise it isn't worth it unless you need to pass tech while pulling.

My fuel/air mods are in my signature. More air than I can use right now, but EGT's might his 1300 on a 11.9 pass so it stays cool

Tows like a champ too!

I would do a stock/475 twin setup and you will have plenty if air plus the spool up is still crazy fast!

No idea on the elevation. I'm in south eastern WI

Tom ran 12.1 @ 110 back in like 2010 on stock cp3/turbo/injectors, but I wouldn't recommend it.

I'm running s475/stocker with 40% overs and stock pump. Time is in sig.

Go fixed vane.

Go fixed vane.

It's an LB7, didn't have any plans to go variable...

Cool, so what do I have to do special @ 626ft above sea level?

Since you have a lb7 don't waste time or money on nozzles until you need injectors. Its not worth the time and money for the small gain. Decent single and dual injections pumps will give you more than enough to pull that off. Alot easier and cheaper to do. IMHO I wouldn't go any smaller than 60% overs if you end up doing injectors.

Knowing that you're getting just about the best air density into the engine as possible!
