DRs on a stock rear?

HessiaN257 · March 30th, 2008, 12:20 PM

Well its track season again here. I have a set of DRs available for me to use once I go, but my question is with my completely stock rear (3.27s,axles,ect.) do I run the risk of snapping something or something along those lines?

My rear end is all stock and i have DR's. only been to the track with them once and i kept it to about 2500rpms just because of what ppl have said about dr's breaking the stock rear.

just don't launch like a bat out of hell and you should be fine.

i left at 4k-4500 on stock rear end... dead hooking at 4 and spinning a tad anything over 4... but i have seen some break at 2500 and some take rev limit launches like champs....

HessiaN257 · March 30th, 2008, 02:06 PM

I wasn't planning on launching very high with them in the first place. I was thinking somewhere around 2500-3000 just to get a good hook.

I launch above 4000 on slicks and just 4.10s no harm yet.... key word yet.

prodrifterx · March 30th, 2008, 07:02 PM

hmm.. thining of doing the same...getting hoosier slicks for cheap tho....launching at 3K and rolling out of the hole sorta at half throttle till im going, then full throttle punch.

i launch my girlfriends vortech gt with a stock rear and 4.10's at about 5500 and haven't had any problems and it has 88k on it

crumbie50 · March 30th, 2008, 08:52 PM

dead hooking is what kills an axle. you wanna keep the rpms high so you get slight spin (2-3 turns of the tire) then hook. that'll get ya the best et and won't risk breakage.

Good to hear guys, I can't wait to see what I am gonna run. Thanks for the input.

crumbie50 · March 30th, 2008, 09:20 PM

If you're really worried about breaking axles, just pick up a set of mosers from summit for 230+ bucks and throw them in. It's a really easy install and will give ya some piece of mind.

drazga97 · March 30th, 2008, 11:40 PM

not to jack your thread but what psi should be run on the street and track for drag radials?

crumbie50 · March 31st, 2008, 12:01 AM

25 psi on the street. start with 15 psi at the strip and work up/down from there.

drazga97 · March 31st, 2008, 12:02 AM

thats what i thought..... how low is too low?

crumbie50 · March 31st, 2008, 01:02 PM

i'd say 12 would be the lowest for a drag radial tire. just make some passes and keep adjusting the pressure until you find what works best with your car.
