Gen III Hemi stroked to 426 with 10psi of boost from a 3.0l Techco twin screw and a TR6060 6 speed...Should be right at 750 to the wheels with an easy to tune cam. Pulling this motor out of my 300C when I drop the new 462 in. Currently N/A it's 540 rwhp.
DSS here in the states already manufactures an independent 9" housing with a universal front mount. Like what you did, you have to weld on custom mounting tabs. The inner stubs will accept a Porsche style CV joint that DSS uses on all their axles/
Nice! Looks like there is plenty of room in the cradle. Who did you get to do the axles and what spline are the hubs? We use DSS for the axles and I was going to use them but if someone already makes them it would save time. Nice job on the housing. I assume you made the custom mounting points?
On the Mopars we run both an Iron and an aluminum version. The Iron are quite a bit stronger and work better with transbrake cars. I'd love to do this to my Supra as well.
Are the 8.8 or 9" a straight axle conversion or IRS? I have a 8.8 IRS in my 300C which pulls 1.4x 60' times at 4400 lbs so I know it will hold up just fine in a Supra at 1000 lbs less.
Anything out there? What do the big hp/tq guys do for a diff that won't come apart on a prepped track with slicks and say 600-700 rwhp? Does anyone make a 9" IRS for the Supra?
Nah.....Gen 3 Hemi.......stock 6.1 is 425hp/420 tq.......cam in that will put it over 500. Just gotta see if it fits between the shock towers. Only weighs 40 lbs more than the stock turbo motor.
This has been a great read so far. I have been toying with the idea of a genIII Hemi and a tr6060 in mine. Need to see if the engine bay is wide enough. Looking forward to seeing yours finished.
Is the clutch assembly a bolt in on the firewall? Looking to lose the automatic......looking to lose a few things but some will hinge on a clutch pedal.
Just picked up a MKIII Supra and was turned onto this forum from a local site. It's a nice rust free car but currently not running due to a bad fuel pump and I suspect idle control valve. I have been looking over some of the threads on the site the last couple of days and I am pretty impressed...
