thunderbird supercoupe irs
I am considering switching out my 9 inch rear end wirh an 8.8
supercoupe irs. I am running a supercharged 289, 375 horse, 425 lbs torque. Will the irs handle the torque. How have the 8.8 irs units held up in cobras. Thanks for your input. Jay. |
They handle it fine. Just don't put on some drag slicks and try and launch the car at 7000rpm. SPF puts them in their cars, and there are a bunch of SPF's with lots more torque and no diff problems. But why switch anyway?
|
I up-graded to an Auburn Pro carrier in my 8.8 and have had no worries.
|
3 reasons for the switch:
#1. I need a winter project. #2. I auto cross the car & believe the irs will perform better. #3. I found a complete irs for $500 dollars & should be able to sell the 9 inch disc. with posi for more. |
I have never seen an LAE or B&B with IRS. is it supposed to be a drop in assembly? The cost of modifying the frame to accept: A-arms out back, hang the center section, and everything else will be a huge pain, but you said you needed a project. What did you get with the "complete irs for $500"
|
I like reason number 2. You are starting a poll aren't you? LOL

I'm checking to make sure the irs hub to hub length is the same as the 9 inch. To shorten or lengthen the irs would be spendy.
The irs I've looked at is a 1992, 327 gears with posi. The unit is 100 percent complete. I actually think the install wil be easy. A wire feed welder & some custom brackets. I will keep you posted. Jay |
