Driveshaft or Rear end?

Assuming that you have deep enough pockets and the will to spend and spend and spend, to get to 1000 hp....what are you going to do with all those horses? You have hp goals...what for? Have you any idea what it takes to get that power to the ground, even on a prepped surface? And then when you have resolved the traction issues....that is when the stuff starts to break. Wondering where you got that 850 number from?

Most of the people around here are in the 800hp range that's why
Gotta stay competitive...right....sounds like a hard core street-racing crowd. Good luck with your plans.
I also have the MMR 302 stroker 950 (cobra block) in my car. Using a 76m turbo. Just gone to a fuel cell. Had the Fore Precision triple pumps and the GT500 dual pumps before that. Also changed from 60 to 80 lb injectors and from a 4r70w to a 2 speed powerglide this build. With every incremental power increase, the rest of the car has to be upgraded. You don't mention tracking the car, so you can get away with less modding. We have to pay full attention to traction issues. The first 60 feet is real important. A major focus of this build has been weight reduction and relocation.

Very hardcore indeed.. It's insane what some of these people are making. I'm going to stick with the stock alluminum block on this build. Trying to get an idea on what turbo I should run. Also plan on going to 80lb injectors as well. With the fuel pumps, I'm thinking of running another dual kenne bell pump, what would you recommend on that? Traction is always going to be a problem I can see. I just don't think 11" wide street radials will be enough.

Had the dual GT500 pumps with 2 KB BAPs, before going to the Fore Precision triple pumps + megadriver. Not sure at what rwhp we did that switch... I don't pay attention to hp numbers. Maybe around 600+??????. Just switched again to a fuel cell (return style system) located in spare wheel insert. Got to watch when using mutliple pump systems. Had two separate GT500 pump failures that contributed to the last built motor going booooom. Mate of mine about a month ago also lost a built motor due to inadequate fuel delivery under high boost causing leaning

I would go 35 spline and a locker if it's going to be street driven @ 850 rwhp. You can also call aubrun and speak with them. They have gear driven LSDs that more street friendly than a locker. A locker and a manual suck. IF you have an auto (which you will have to have at 850 rwhp) they are supposed to be much more tolerable.
If you are going to race. Get a spool.

[QUOTE=BlackS281;7011783]I know. I'm only going to be at 500rwhp with my current setup. I have plans to get a larger turbo and more fuel. The transmission that I have will hold that power.[/QUOTE]
Maybe . . .
People have spoke about how they live for a while but are just not as beefy as the 4r.
I wish you luck none the less.

Agree with the 4r70w. The sig pic shows car launching hard with the 4r + transbrake and 2 step. After shredding a trutrac, went with full spool, but at that time car had minimal street use. The spool was a major PITA for street driving.

Stock axles (31 spline) detroit locker.

be and they have had many launches on them. Also, I'm running a truetrac so I won't have to hear that annoying noise with the locker. I was also told that running a spool would increase the life of the axles but I wouldn't want it to be a PITA when I'm driving on the street.
