...or rather, "thinking outside the engine bay".  This guy is stuffing a Judd V10 into a new Supra.  Not sure if there is not a way to put accessories on a Judd engine or if he realized there simply wasn't enough room for them, but his solution for the alternator is genius*.  He's also installed an electric power steering pump and battery in that area where the factory fuel tank used to be.  Excellent use of space.

*maybe this is common, but I've never seen it, and frankly, would have never thought of it.

 

Edit:  The Judd V10 does come with a 35A alternator.  That alternator will not be enough so it will be used to start the car and maybe run a fan, but the 270A alternator in the rear will do all the heavy lifting and he doesn't want that load on the engine.  Apparently, this "mod" is common Off-Road, but not seen in Drifting or at a track.  Seems odd though, I'd expect this mod to be for track use, not daily driving and especially not Off-Road. The pulley on the alternator will eventually have a clutch in it so when the brakes are applied and everything comes to an abrupt stop, the alternator can spin down freely.  Until then, he expects to V-belt to slip and wear out quickly.

I hope he never drives the car in the rain or snow. Alternators don't like working when they get wet.

This will be a 100% track-day vehicle, and even then likely not driven often.  I forget the exact number, but the Judd engines need a complete tear down and rebuild every 3,000 miles or something.   ...just looked, it's 3,000km, so, 1,800mi.

Interesting.... never heard of the Judd engines.  I'd like to hear that thing at the rated 11,000 RPM.  The 4.2L version makes 775 HP and weighs 300#.

 

[EDIT] they have a video w/ sound on their website.
