1500HP recipe drag only turbo build
Iam about to get started building a turbo drag only car prob for the drag radial class and was wondering as far as the engine goes what block and all internals would be the best. And I'am curious on the heads and rockers arms. Budget is high so I plan on the best of everything. Not sure yet of a twin set up or big single.

If money is not an issue then I'd go twins just for flexability sake. I'd also go with a block that can handle that kind of structural pressure.
Here's a build that I was looking at.

LSX block forged rotating assembly and heads that can clamp those forces. 2000+ Crank HP. Twin 88's.

as everyone says though, whatever you think it is gonna cost,it will wind up costing quite a bit more than expected so be prepared.good luck

1500rwhp is not hard to make. Problem with 1500rwhp is that in most Drag Radial classes its gonna take alot more. If you are thinking Outlaw Drag Radial then you need to be thinking 2000+ rwhp.
Engine block opinions will vary greatly. You have the LSX block, ERL, VA Speed, RHS, and so on. Each with their own advantages/disadvantages. Same goes for Heads and Valve train. Internals I like Callies Billet Crank, Billet or Aluminum Rods, and a number of different options on pistons.
The Single Vs Twin turbo debate depends on the type of Class or Classes you wanna run. Either can be built to run the Number. Alot of guys do Big Singles with great results. Alot of Guys do Big Twins with Great results.
At the end of the day there are alot of variables. Best bet is to sit down and call some shops up and see what they recommend. We all have different approaches to the same end result.

X275 single 88. Outlaw 275 Twins. Definatley get the rules. I spec Turbo setups daily for guys looking to step up into class racing. The Specific class rules are alway taken into consideration. This is a super exspensive Hobby we all have. At the end of the day you have to treat it like a Business itself.

RPM outlaw is twin 91's on a BB no other restrictions
King of the Street (275SR) no turbo BB, any size SB + single turbo (certain CI subject to additional weight penalties) Garrett GT47\88, Turbonetics HP\88, & Precision HP\8847H - maximum size of 88.0 mm /3.464” – inducer wheel diameter at the point where the leading edge of the compressor wheel meets the inlet housing. Inlet housing is permitted a maximum inlet diameter of 3.544”where the leading edge of the compressor wheel meets the housing.
Couldnt find any rules for NDRRA outlaw 275
ORTC doesnt run outlaw 275 that i can find.

Seriously, you need to determine a class you want to run so you can build to the rules/restrictions. Are you looking at the LS only, Drag Radial classes or something other?
"I forgot to say that I think I want to run on alcohol also".
Alcohol probably won't be allowed in most "1500 HP" classes depending on what kind of car are you putting this in . Race gas will give you a much wider venue for classes you can run.

That right! I'am used to running 150lbs on my tractor it was a twin turbo setup from hypermax in gilberts IL. some of the guys I ran with was running 180 to 200.crazy right? I do understand I need to fig out what classes are out there in my area. The car is a 95 camaro and it will be built with LS engine but not just for LS classes. Drag radial classes are small around central iowa.
