Twin turbo gains

[coker6303]

Twin it, stock/475 and don't look back. Worth every penny! Town better, runs better and sounds awesome too!!!

Or a single 366 or something similar, that way you clean everything up under the hood.

I would have to find my slip but I am pretty sure I was in the 1.5's 60'. I had M&H radials, QA1's, Caltracs, and some weight reduction. It was the normal, tailgate, spare tire, back seat, one battery, no hitch. I think I was around 6600#'s or so. About 800' elevation.

Another thing too, the truck only had around 35,000 miles on it, so my pump was pretty healthy still.

I've got basically a brand new injection pump under the hood now. So now I just need to sell my enclosed trailer and I'll order studs and twins

Nice! Do you daily drive it? Only beat on it at the track?

I do not daily drive it. Probably similar driving habits to you from what you've said. I drive it on the weekends if it's nice out and take it on long road trips. Maybe go to the track 2-3 times a year. I've been most impressed by the twins with how they react on the street actually, it's a very smooth ride for long trips and everything, but when the 2nd turbo lights it really puts you in your seat. I think its a shame to get rid of the VVTs on these trucks, although I would definitely consider a drop-in VVT as well.

Poor Dustin. Looks like he will have to settle for third place for a while/forever. Lol In case anyone is wondering we have a list at work for fastest diesels. Right now it's me @ 11.85 then Jake @ 12.61 and in a close third Dustin @ 12.69.

Thats the beauty of vgt in a twin setup. Instant spool and the 475 will keep things moving up top. Tough to beat twins for what you're looking to do!

Same as Harbin.

Ran 7,41 on 1/8.

11,73 on 1/4 at 113 mph with 1,58 60ft.

Stock intercooler, stock head stud, no up pipe or manifold, 45% nozzles, s475 over stock.

I could have squeeze 11,6X from that setup.

Last year i added dual fueler and BOOM. This year built motor and bigger twins.

S475 is the most common atmospheric charger in a basic twin setup

And that's what I don't want, but I want MO POWA! Apparently you can't have both without MO MONEY!

Before doing some turbo work, my big ass truck with built motor, 475 over stock, dual fuelers, and 45% over injectors ran a 12.3-12.6 at 111-113mph. Just FYI, with a completely stock motor and fueling, the twins killed my motor in 2 months running 2800-3200us tune. Be prepared for the worst if you do twins

 

[Benltr]

Dual fueler killed my motor. Basic fueling 45% + stock pump was reliable. For info, dual fueler was 4-5 mph faster on the 1/8 vs stock pump on the same setup
