Here’s a project that was completed by a FB friend. Apparently a huge increase in power but torque suffered. Not ideal for a street engine & something I intend to avoid with my design...

A specific book I sourced, ordered & it finally arrived today! Looking forward to readIng it cover to cover. Even this edition was published many, many years ago but the science still remains the same. Just checking I haven’t missed something before I forge ahead! Washing down the engine for the fabricator....1C60D169-A367-48F6-A846-9C9AC505F87C.jpeg

Finally I can send my prototype engine off to the fabricator next week since I'd been waiting for them to finish a custom exhaust on of all things a rare Lamborgini 4x4! Pix to follow when I plug all the openings and give it a wash before loading it on the trailer. It's pedal to the metal now, since I'm running out of time to get this finished but there's nothing like a bit of pressure to lite the fire and get you moving!

As you wish Michel! Degreaser & cold pressure wash x 2 + degreaser & warm pressure wash x 1. I could get it even better with a hot wash & scrub but that’s enough for now. I dropped it all off at my fabricator on Monday. 🎉🥳🤞🏻🤞🏻🤞🏻🤞🏻

Well I contacted my fabricator around 3 weeks ago, just before a spontaneous holiday to Bali. Seems he was unable to construct some of my final design with the space constraints. So I went back to the drawing board for a rethink & came up with a revised design which could be even better. It certainly features some unusual & cool elements...

I’ll finish the scale drawing shortly & send it off to the builder hopefully Wednesday. Once built, it’ll be onto all the wiring & plumbing on ‘Midnight Express’ to get it finally ready for a chassis, or hub dyno.

Two heads with one stone... My spare engine now becomes the next test bed for a new manifold.

Plus the original & undamaged manifold goes on Red Bull.

This is a bit more suitable for Kjet! Fitted to a Delorean, but I’m not sure if it’s been modified from the original configuration.

I'm not sure either, but the PRV 6 that was in the Delorean wasn't the best performer, so it wouldn't surprise me if this is a custom job. That engine looks pretty big, so wouldn't surprise me if its a V8 conversion.
