Hi folks,
This is my first post, so be gentle. I'm a Ford enthusiast in the UK and I am looking at using a Cobra 8.8" IRS Differential on a drag project car for next summer. The car at present (Ford Sierra Cosworth) uses a rather puny 7.5" rear diff. I do not want to go to a live axle setup and the proper Ford Touring Car spec 9" IRS differential would cost me about $5k here.
So i'm looking for two things :-
1) Any general comments regarding using the IRS 8.8" differential with approx 380bhp/340ft-lb and a 100-150hp nitrous shot (I understand the half-shafts may be a problem, but mine will be custom anyway, so I can go super strong from the start)..
2) Someone in the states who could build me a strong complete diff. I've seen the housing for sale from Ford Racing (~$500). I've read various texts that state you can use 'any' 8.8" differential unit, and other texts that say not all are compatible with the IRS setup. I'm not sure what else i'd need or where to buy them from, I guess the differential, gear set, bearing + seal set, stub axles and the driveshaft flange (can this come with the flat flange or a UJ only?), a girdle/strengthening plate?.. which is why i'd like someone to build it all up for me..
So if you can recommend a company who can build me what I want i'd appreciate it..
Please only reply if you have personal experience of the above as the replies may directly influence a potentially expensive purchase :-D
Thanks for your time..
