35 spline axles enough for twin turbo build?
I have a 2002 Firehawk with a 404" LS2 and Twin billet wheel ball bearing gt35 turbos. I never made a Dyno pull at full power but it made 580hp @ 4psi on a mustang Dyno. It should be capable of making it to the 1000hp mark
I built the car with the idea of having a really good working street strip car
It has a th400 and a Moser 9" rear
I have BS3 fuel injection with a Leash Boost/Bump box
I wanted it to be capable of some really good 60' times
I am currently planning on narrowing my 9" so I can run a different backspacing 15" drag wheel. I will need to get a shorter axle.
I am wondering if my 35 spline axles are strong enough for my car or should I consider stepping up to 40 spline axles. I only drive the car 1-2k miles a year, but I would like to avoid changing the spool(If I swap to 40 spline axles)
I want to do what is best but if 35 spline axles will work then it will save time and money.
Thanks

35 will work, I wouldn't gun drill a 35 spline axle fwiw. Lighten flanges sure that will be fine, just don't gun drill them and you will be fine.
I would buy a quality 35 spline axle from someone reputable, if you want to go the best possible 35 spline option mark Williams would be my recommendation.
Fwiw, I'm putting 35 spline mark Williams axles in my 12 bolt that's 13 inches narrower than a stock width 12 bolt, along with their 35 spline spool, and a 4.10 pro gear set. Car is about 3050 lbs and will see 850 n/a hp and about that much nitrous on top of that.
I have no real concerns about the axles or rear end being a problem at this level.

I'm deff not thinking about going gun drilled. I called strange about their pro race Hy-Tuf axles, but the guy acted like they would be too brittle to run on the street any. I'm going to call Mark Williams tomorrow. Only thing about MW is I wonder if I have to change over to a MW spool?

You didn't mention the weight of the car or what kind of 60's you're at least anticipating. You mentioned 1000 horsepower and if we assume it'll be 3300 lbs or less being a street car and maybe yanking some 1.3 or slower 60's..........I'd probably feel comfortable with the 35's.
I run 40 spline **** in the truck, but the lightest it has ever been is 4110lbs with a 60' goal in the 1.20's. It has been a best of 1.34. I use all Strange rear components except the housing which is a Racecraft.

35 spline Strange Pro Race axles will be fine for your needs. Don't bother with any light weight options as you will never see any gains from it on a axle in your application, and I NEVER suggest any sort of flange mods to an axle if the car will see street use.

If MW will sell 35 spline axles that will work with my Moser spool then that will be the way for me to do this
I can send my moser axles back and have them shortened and drilled for 5/8" studs for $185 plus shipping but how good will the Moser axles actually be? I've heard Moser 35 spline axles don't normally break....they bend the splines

I wouldn't on a street car, that was my main thought.
I don't know if I want to do the gun drilling or not with my sled at this point. Cost isn't the concern... more am I asking for trouble now doing that on something smaller than a 40 spline. Especially if it ever shakes the tire.

You will be fine with a set of the Strange 35 spline Hy-Tuff axles on limited street use. Cost of the axles, bearings, and 1/2" stud kit will be about 470.00. The same thing from MW will run well over 700.00
Give us a call, we will be happy to help you get the right parts for your needs at a great price.

Kinda like the difference between a mild steel and chromoly k-member in street use. The risks of a failure from the 5 pounds or less difference between the two materials(due to material thickness only) is just not worth it.
I would recommend running a lighter wheel/tire combo and lighter brakes well before a lightened axle. The further away from center you get the greater the benefit of reduced rotating mass.
