I have a BW 9bolt with 3.27 gears and wanted to know if it Will hold up very long running mid to high 11s in the 1/4 with Nitto street slicks, and a 3500 stall? Or what can I do to make it stronger? Thanks for the help guys.

 

You might want to start checking on prices for a 10 bolt just in case. If you go to the track a lot, time is not on your side.

 

I go to the track about 5 times a year, but this is the first year with the heads, cam, and stall so I might go a couple more times, is this to the point of to much stress on it? If so how much could I sell the 9 bolt for? it has 3.27gears and good Posi.

 

Um, if he wants to reliably run in the elevens, the 10 bolt really isnt an option. Do you mean 12 bolt?

 

i think it should hold up. there's a guy on here that's running a big block with his 9 bolt...his name is miles....in fact here you go....

hope this helps

 

Yeah, a 12 bolt would be much better but I think a 10 bolt would hold up depending on how much he goes to the track. One or two times a year wouldn't justify the cost of a 12bolt, IMO. You may bust the 10 bolt at some time. Once that happens, buy the 12 bolt.

 

why would he want to go backwards on reliability, the 9 bolt is leaps and bounds stronger than a 10 bolt any day. if you really want the best get a 9" built for a third gen. pricey but hard to hurt with any motor.

 

Definately stay with the 9 bolt. The axles are beefier and they bolt in. The 10 bolt IMO would be a step backward.

By the way I just replaced the posi unit in my 3.27 geared 9 bolt and it is good again.

I for one am very impressed with my 9 bolt, it has seen many 3500-4000rpm launches on drag radials and never even made noise. The posi unit finally let go with about 130000 hard miles on it. And about the last 20k was behind a 5speed. I am just going to put a used posi in it and go for it again. It'll hold up, I think if I start hooking real hard with mine it will probably break, but miles has had his behind a BB for quite some time.
