Ran the car and my best was 11.6 at 127 with huge traction issues and missed third... lowered the air pressure to 17 psi launched at 2500 and shifted sencond then third and a huge BAAAMMMM LOL THEN ROLLED AND clunk clunk clunk .......going straight axle any pointers on what straight axle to use......
Went to the track and boom said the axle lol
- Thread starter sabotage
- Start date
Have you put a bushing kit in your IRS? What kind of tires were you running? the IRS will live if you treat it right.
I have a SRA out of a 03 Mach. I love it. Same gears, same brakes. Everything just bolted right in. Plenty of info about SRA swaps on this site.
Met Hugo last night at the track. We were at Sacramento raceway in Sacramento. I guess I left when you made the pass when your cobra broke. It was nice meeting you Hugo.:beer:
What tires ??? Very surprised it broke in 3rd... :??: Any wheel hop ??
Bushings & tires? I know I'm pushing the stock half-shafts,but that's what trailers are for!! mine are still original.
I raced on my stock half shafts for 6 years launching on slicks and spray getting low 1.5x 60' and mid 10s.
The IRS had poly bushings and a diff brace.
I believe the bias ply drag tires absorbed the shock and saved the half shafts.

This. Breaking in 3rd is a little odd...
I agree
I wanna known how you snapped an axle in 3rd gear? Bias ply's aren't gonna help him here Jimmy it wasn't from launch shock..
i was running nitto drag radial 315s 17in rim .....i didnt have any issues with the pump gas tune lol ...wanted more so i switch to the race gas tune ...my friend took videos ill post them as soon i get a hold of them .......yea I have to watch the video I think it was third:shrug: ...it was not first because i was out there...and it still rolled passed the 1/4:banana:lol....

very nice meeting you too bro ....nothing like meeting people that are into the same thing lol
yea no wheel hop its got fulltilt boogie bushings ford racing newer style cover...it was at sacramento hottt as hell ....I made my last pass at 11 pm it had cooled down for over two hours IAT was in the 70S instead of in 100s during the day .....so it was on a mission i felt it moving till it broke....:burn:
Drag radials transmit too much shock, bias ply drag slicks will wind up and absorb most of the shock yet the power is stored in the sidewalls almost like a spring.
Drag radials are much harsher power delivery.
My vote(if I get one) is keep the built IRS, sell the drag radials, get bias ply slicks and spare wheels for the drags.
And R compound treaded DOT road race tires(R888s!) for the grip on the street that won't put you into a guard rail at the slightest sprinkle of rain.
Wise words Jimmy!:thumbsup:
