And get that fancy, shmancy air induction system put in. What turbo are you currently running?

Billet s482 with race cover.

Dude I have all that stuff all the way down to the hvhf IDM and I have barely hit 650 according to track times! LOL

Dave I don't mean to step on any toes, but I would say that the 900+ HP has to be using nitrous. If so, How much nitrous?

no offense taken...

there's much more to an injector than cc & nozzle size, as I'm sure you're aware.

There are probably performance injectors on Ebay, that share similar cc & nozzle numbers as well...but I don't think anyone would truly expect them to perform.

all our stated hp numbers are fuel only, no nitrous, single turbo.

all of our dyno runs are performed in accordance with SAE standards for operating an engine dyno, without any correction factor.

same combination with 2 .062 nitrous jets, it makes nearly 1100hp, consistently.

OK. Well I have a set of Unlimited's awesome panty dropper 400/400's so.... LOL

Aww I just need some more dialing in is all. I need to get Matt up here for some live tuning. It's just a long annoying process.

Very impressive for the old dinosaur.

I think you need a different turbo.

What turbine wheel ?

vanderchevy18 · Sep 30, 2013

S482 with billet compressor and race cover. 87 wheel I believe.

This is a shot in the dark I'm sure I will get told no but. If you guys don't mind me asking (golfer) what kind of pw/timming is in your tunes for the 900hp.

Haven't tried the S480/96 with a billet compressor wheel and race cover, but my track times / traps are better with the Billet S475/87 over a S480/96 Cast T4I. Personally, I thought the S480 was a tad big for fuel only, needed a good stage of gas to stay on top of the charger after the gear changes. I'm sure the aftermarket cam would help, since it would raise the rpm band higher. That charger loved the juice though haha.

Even with a smallish GTX4202R and my tuning 900 fwhp would be easily attained.

I have always said lottsa people with the same parts yet only a handful of fast trucks even fewer on fuel only.
The combination of parts and tuning is much more important than the sum of the parts by themselves.

I have had 5 different people tune it and so far my favorite as far as idle quality, shifts, etc is Matt's.

I ran a best of 12.75@105 weighing 7800# and the charger choked on every shift. Next time I run I'll bump the shift points up to 3800 from the current 3250 and introduce a healthy shot of nitrous oxide. I'm going to make that big bastard stay lit.

Agreed, ive run many combos. Some flat work better than ever imagined and some that on paper would rock out but just fall short.

You sure you dont have a boost leak ? Or something ?

Its an s482. Without nitrous. Shifting at 3250 rpm. Come on guys. There's going to be some lag.
