The second time i used the n2nb wot box . First time i left at 2500 and rhe engine fall on its face. The track was very sticky. So the second run I left at 4500 and BANG .

If i wanted a SRA i d buy a mach1 loll
I had no wheel hop , just a dead hook . I have the full tilt boogie kit and yesterday i inspect , check torque on all bolt .

The tire would probably be the issue. Put a bias ply tire with some sidewall on it in the car and see what happens
Drag radials are no bueno.
^^^^ lol
I Race for the last 10 years with a Foxbody , lunch at 5000 on slick ... It s the first time with a cobra at the track and my mind CANNOT slip the clutch . It s like a on off switch when the light goes down . I had 15psi at 4500 on the WOT box ... If the lunch control is too hard for the car even with full slick I will shut it off .
Tousley can be a good solution but Is it possible to change just the center axle and the boot , on front wheel drive we can buy the axel by parts.
I'm not fix between 3.73 and 26in or 4.10 w/28 . To be honnest I like the 3.55. I had the 4.10 on my fox and the 3.55 is more street friendly.
And last I think a new diff cover from FRPP can be a good upgrade too , I have always a small drip of oil .
put a sra in it and use whatever tire you want with the 2step.
Every post you make about the IRS you trash it. Yet you never even gave yours a chance, instead you joined the band wagon and went solid, even before your car could put up a respectable number.
Its fine you have your opinion and..... your car your choice, but to constantly bad mouth and push your view is unacceptable. I myself, have done over 15- 6k rpm dumps on a et streets cutting 1.60 60s in a 3800lb car and havent broke a halfshaft yet! I now have 720rwhp and plan on pushing the IRS to its limits, my goal is 9s on a IRS, it has been done and will be done again.
Original poster, the IRS can be made to handle the two step, FTBR kit, subframe connectors, IRS brace, and qa1 adjustable shocks paired with MT ET STREETS or ET DRAGS. Bias plys will keep the IRS alive!:rolling:;-)
Don't feel bad, I had the same issue. My problem was track wasn't hooking, went up to 5k and it hooked. Dead hook on DR and IRS is no good...
I think it can be hit or miss with the IRS which is why I went SRA. There are plenty of people who have made tons of launches on their IRS and have broken nothing. Then there are those who break it the first time out. I just couldnt justify spending thousands of dollars on half shafts when I could have a fully built SRA for less than that.
I loved how my IRS looked but I just didnt want to worry about snapping anythings. More power to those of you launching on IRS.

the reason i did sra is because of the exact reason tb said, it seems to be hit or miss. i had the full ftbr kit and braced and 28x10x16" bias plys and nobody could tell me if the irs would handle a 2step clutch dump. so i didn't feel like getting stranded at the track and went sra. I very rarely get to trailer my car to the track and that's the main reason, i dont want to get left there while all my gm buddies talk shit about my car breaking. If i was into handling at all i would have prolly kept it, but for me the positives of the sra outweighed the positives of the irs, and no point waiting to do the swap.
A solid axle can leave you stranded just as easy as a irs. Coming from being a "gm" guy, I've broke my share of 10 and 12 bolts. Anything will break with the right conditions and abuse, that's the story of drag racing!

SRA's are not unbreakable! :read:
Any time you're launching hard and do it enough, you will find the weakest link just as this SRA conversion found:

Im gonna call bullshit on the whole bias ply/drag radial tire argument. 3 years on 315 35 17 Mt dr's and no problems. This year 2nd time out with my new 27x11.5 Hoosiers and my axle looked just like that. Product of excellent traction. Found the weak link at 5k.
It's all in how you slip the clutch
