billet rods. If you have money to build 990hp you have money to buy proper rods
dual cp3
200% overs
Tuning
S366 and S480
T4 manifold with provision for external gate
Springs and keepers
Studs top and bottom
Proper tuning to clean it all up and obviously a transmission to support it
I like a bigger injector to keep duration down and yes you could use a cheaper single with some 12v rods to get there but a nice set of compounds makes it more usable regardless of application. We have seen similar builds break 1000 regularly and customers are happy as hell with them. The guys trying to make 1000hp on a single usually have something bad to say about the driveability.

How would those injectors do with a lot of idle time and cold starts? I know that would depend a lot on the tuning, just curious how it would be for a daily in cold weather.
I would want a smaller S363sx-e or something instead of a 366 for 1k hp. Other than that I agree with the rest of the setup.

We Did a build here at the shop for a customer....very streetable, very clean, useable power
-DJ Performance LongBlock With FSR Pistons
- 188/220 I believe
- 63/477 Compounds
- F1 Apex 7.5's
- Dual Fuelers
and all other Supporting mods...
Alot of money invested in this build, but its very useable power and drives so nice... for that power level. Injectors were the limiting factor, I should have went larger and detuned.

We are putting 200% overs in our truck with an almost identical build sheet. Putting an S483 in place of the S480 though. We get pretty darn cold here (Indiana) so we shall see. I honestly don't plan on daily driving a 1200+ hp truck in the snow though. As for idle time I am sure they will haze a bit. I just prefer dealing with some idle haze over having to stretch duration way out and sacrifice durability on that end. Just a personal opinion so take it as that of course. I am sure there are ten different ways to skin the cat when it comes to 1000hp and up injectors. The other reason is that quality 200% over injectors are $3500+ so if a guy wants to take his build further a year down the road he doesn't have to reinvest in injectors again.
Honestly the s366 drives so nice on a common rail, I prefer the larger turbine it offers on the common rail, and if a guy wanted to upgrade that 80 to an 85 later he could make that one change and lay down a much larger number. Speaking strictly from the 1000hp point of view of course here. Could put the 64 sx-e in place of the 66 and I would still be happy with the setup but again it leaves room to grow with the 66.
If a guy wanted to tow he could do the 63 or 64 but I doubt anybody with a 1000hp (sorry 990hp) truck really wants to do much towing.

For sake of discussion, a reasonable budget that would provide decent longevity but not be limited to Chinesium turbos.
LOL Not after they're done!
Curious why the compound turbo setup? Aren't there plenty of streetable s400-frame options for 990?
In my world, aftermarket rods are a requirement above 800.

I only said the rods for the guys who may potentially read this in the future. Too many guys call me thinking they need 1200hp worth of air for their 12v rod engine.
Yes and no on the s400s. A lot more guys put large S400s on and say they make 1000hp because somebody else with an entirely different build did it than actually do it. In my opinion at this power level money can't be an issue. Obviously unnecessary money doesn't need to be spent but I prefer compounds at that power level. If it were strictly for competition then I can see a single but prefer compounds.

I should have put rods weren't optional in the original post.
I'm curious if we'll see other opinions in here with a single CP3 setup? Or nitrous?

I ran a s476/87 with 150% over injectors,built trans and valve springs and push rods was a fun daily and ran 10.60s no traction bars and nitto 420s then I wanted to go faster had a billet rod motor built put 471 over 486 compounds and bigger injectors and I miss the simple single turbo drive everyday truck
