Whippled 408 thoughts
#11
Ahh, lots of questions & input.
His best runs are 13.3's at 100 mph.
I agree the stock 76mm TB is likely holding him back. I'm still running my 76mm and in the low 12's, but only feeding 325 cubes. Not sure what would have to be done to get a larger TB on the Whipple.
If your buddy decides to intercooler which btw. I would recommend going A2W.Not too sure why Pat says intercooling is a bad idea.Unless its because,of the tunning difficulties he ran into using a A2A.Which can be a hassle but,I know is possible.So like I was sayin if hes interested in intercooling I have a lower Whipple blower manifold already setup with a 3" outlet welded on.I also have a fabricated T.B. inlet setup for a Whipple blower.The opening for the T.B. is 96mm so plenty big for a 2.3l twinscrew.
Thanks everybody, keep it coming!!

Im pretty sure I get what your sayin but,I think you may have have wrote it backwards.With that being said no matter what lowering your iat's will net some power.Which is what the mods I mentioned will do.When my truck was runinng wayyyyy back when (early 2010 lol).On a 70 degree day give or take iat's would rise no more then 25-30 degrees through a 0-130 pass at 11-12#'s.This is using the mods mentioned above.They will make a big difference if you push the blower hard enough.What size upper and lower pulley does your buddy have on his truck?

The guy who built the engine is also a friend. I just stole a couple pics off his FB account, haha!
The lower pulley is aftermarket, SFI, and larger than stock. I don't know the size though. The upper pulley is smaller than stock, and the only one he has for it. I don't know the size, and can't find a pic of it. I'm sure I could measure it next week sometime.

Your friend needs headers and an intercooler and his truck will be a different animal. I would add a larger throttle body as well.
I was running around 12psi on my stock 6.0L with a 2.3 intercooled whipple and jba shorty headers and I was seeing 13.01 1/4 mile times out of my full size Denali.

Headers should be first thing. Can't get it in unless you get it out.
On a ford L boost went down and power went up just by increasing headers from 1.5 to 1 7/8.
Now that started at 24psi and went down to 21.
Slightly different then our trucks but you getvthe idea.
Meth and intercooler is only needed if there is a heat problem.
300lbs is a lot and very easy to be under estamated. And surely will not help the 60fts.
Just because it's a larger engine does not mean it's making that muchore power.
It always hard comparing trucks and set ups seeing how no combinations are the same.
Put a 150 shot on it and let the big dog eat.
That will wake it up.
