After much thought I think you guys could help me out with this. I'm planning on being somewhat competitive in both pulling this year my area in a hot street class and also I love drag racing. Truck is an 05 quad cab long bed auto. Goals are as I said to be competitive in a hot street class for pulling and I'd like to see low 12's when I hit the strip. My plans are 120 horse injectors, Billet wheel S366, Second or third gen manifold (still undecided) , intercooler, intake horn, deleted grid heater, arp studs, stroker cp3 (somewhere around 85% over range). Current mods are Smarty/MP8, Fass 150, fully built auto, afe stage 2 intake, 4 inch exhaust. Current best time on the strip was a [email protected] on 33x12.50. Now for having goals like that, should that put me where I want to? What would you do differently and if it was yours?

You need more then 120's. 150's would be the minimum you can get by with to be competitive pulling. 366 and 120's are the small. I ran that setup and that turbo can handle a lot more. Honestly, a 466 is gonna be a more solid turbo for sled pulling and you can throw a lot more fuel at it. You'll probably be told to buy the FMW 467..

How well do they spool ? I'm going to be doing drag racing with it also and I do plan to drive it besides to events so I'd prefer something that isn't very laggy hence I was thinking the 366.

do you think 120s would be to small for the stock/s475? I just purchased DDP 120s and I've been told that's a great set up, is it not? I do plan on replacing the stock with a 63ish later on.

I don't like the 66 but I've also got a 6spd so that doesn't help. With UDC tuning it can be manageable but I'd go with 150's to be partially competitive.

The following is the rules everybody up here uses for the 2.6 class. And if that's the case a clipped 400 series would be illegal to my understanding would it not?

Turbocharger: The vehicle is limited to a single turbocharger; the inducer bore on the compressor housing may be 2.6”. The inlet will be measured using a 2.65-inch plug or internal calipers. Bushing from any larger turbo size down to a 2.6 turbo is PROHIBITED. A stock map width enhancement (MWE) groove is allowed. No MWE groove will be allowed that has a width greater than 1/4 inch. All provisions allowing air to the wheel other than via the bore and the MWE groove are prohibited. 6.4 liter Powerstroke engines may utilize the factory twin-turbo configuration.

Brother I hate to break it to you in the 2.6 class to be competitive. You going to need to spend lots of money. Down in my neck of the woods the lowest HP truck is 975 and has 25k in just the motor. Suspension,weight box,water to air, lockers,track bars,loops,bump stops,tires ect he has another 18k. So that gives you an idea. What it's going to take. Valair1 which is Dan Vallance pulls in 2.6 class took him two yrs to get his motor done so he could compete and cost him 41k just motor. Turbo alone was 5200. I would like to see you succeed and compete man. But to do it right and hold it together for more than one pull 35k the minimum.

Planning on running a 2.6 class yes and some of the guys get pretty wild that are in the areas I'll be pulling in.
Ill give u the specs on the 975 truck down here motor wise.

Hx60 2.6
200hp injectors
Dual modified pumps
Some massive cam that require cut pistons valve relief
P&P head intake valve changed to exhaust valve side draft
Carrillo connection rods
Fluid dampner
Water to air
Dual fans
Polished crank
Balanced motor bored 20over
And some other odds and ends that cost money.

This winter he stepping up to 400hp injectors as he needs more fuel to get on top of that charger down low more.

My plans are to run a hot street class/2.6, hot street is basically for the trucks that are still driven on the road, don't run hanging weights, 2 inches of suspension, sometimes limited on use of traction bars, but still have work done to them. Turbo limitations is usually the same though. Ill be running hot street as much as possible but some of the events use different rules and classes and goes from stock which is only 3 visible mods to 2.6.

With proper UDC tuning on an SSR I made my box s366 cometely street drive able with exergy 60%s (120s). And it was a 6spd. I had to actually dial back the fuel to keep drive pressure down with the 120s. So I dont think 150s are necessary. Your going to over speed that little s366 If its non gated. Mine even dialed back still peaked 58psi boost and 60psi drive. You should be in the high 675-700 range with good tuning. We have a class like you are talking about by my house more of a street class with 2.6 limitations. But like mentioned being competitive at that level is tough. I had near the same setup on my 03' I just sold and it ran good and pulled good. Hopefully it works out for ya. Maybe a slightly under powered perfect weight distributed under dog!?

With a long box its got an advantage of weight and in the right place.

Yeah the truck deffinately has the best body style a guy could ask for when it comes to pulling. And as for the 66 plans were to switch over to udc, and run a billet fleece 66/73 which they had a 06 lay 760/14xx with efi live. So I think should be able to get it into the 700s atleast pretty easily with some good udc tuning.

Those are impressive numbers for a 66/73/.91 especially having to turn it down with 120's. Mine would hit 55 psi max and that was with TNT sw7. I also have a cam, P&P and 3 angle valve job with an increase of intake and exhaust flow done by enterprise engine. And mine could still easily use more fuel. I'm thinking tuning with UDC was the ticket of helping you spool it but I've got a buddy on here with the same turbo, dual pumps and 150's behind a G56 and he's got UDC.. he still hates that tubro even with a spool valve lol

I hear a lot of people hate it but man I loved mine. It drove great I towed some with it it spooled awesome. By 2000-2100 you were up up and away lol... getting up full boost, did it have some lag, yes. But it was not at all what you would think or what I have heard from others. I liked it so much I found another one I'm getting ready to mount on my new 06 build with a s483 underneath

Getting up in size you'll obviously have to deal with some amount of lag. But going with a billet wheel for example is a really good way to help it light fast. My buddy had mounted a 466 on his 6.7 and it's bone stock except for deletes n a h&s and it actually lights it pretty decently even on the stock software. I know they say the 6.7 will spool a larger turbo much easier due to the larger displacement but even with the added fuel and whatnot I don't see why everybody thinks it wouldn't be a street able turbo on a 5.9 without running 180s or 200s. and it would leave me room to grow with less egts at the current moment and I'd have no need to cut the fuel back on the 120s like you did.
