I actually don't mind that idea! I think it would work well. The heat in the charge would have more time to do its thing.

I was happy with the unleaded setup. It would only be to see how much it could make still using the Hyundai TB and standard manifold.

Might try that tomorrow before I pull the engine off the stand.

Its something a little different. Twin VNT turbos on an A12. probably wont make a lot of power. More something that looks OK. Ive always wanted to have a play with a VNT turbo.

This one will be a slow process, but ill update as it happens.

Matt, Good work on the manifold! I do think the 2 injector arrangment you have made will work well. The injectors are pointing toward the ports and the injector size can be halved compared to a single. This should also help as the droplet sized will be smaller, aiding vapourization.

D, These Mazda guys you are referring too that are using Falcon TBI, are their applications turbocharged???

The facory TBI setups all seem to have water heated manifolds. I totally agree that heating the incomming air is #OOPS#! Best thing to do would be to fit 4 injectors pointed into the warm ports, This vapourizes the fuel and pulls heat out of the air.

This whole project is about seeing how simply and cheaply reasonable power can be made on a stock a12 using basic parts. Thats why I dont mind a compromise or 10, lol. Thats why I think the J pipe has merrit.

If it makes 100Kw with a J pipe and standard manifolds with a single injector for around $1200. That would be pretty cool!

Thinking about this some more.. If the J was made from steam pipe and sleaved neatly up into the standard exhaust manifold, the turbo may not need to be braced. I'd probably drill and tap the standard exhaust manifold stud holes up from 8mm to 10mm as well.

Hi Dave, I certainly think your idea has some merit. The turbo manifold is probably the hardest thing for people to make. Using the standard manifold would also fix the atomization problems. The gasket between the two manifolds could be a weak link though. Separating the manifolds to replace the gasket usually involves snapping off the rusty bolts in the exhaust manifold. These would have to be re drilled and tapped.

Two flanges would still have to be made, one to bolt to the manifold and one for the turbo. The turbo would probably have to be supported as well, so a bit of extra fabrication there.

Probably a little bit less work than building a manifold from scratch and it will fix the atomization issue.

I may give it a go if I can find some more motivation.

Thanks for sharing

It doesn't seem to like the 2200cc injector and E85. Not sure what's going on yet. I think I need a bit of a break from it for a day or so, then come back to it with a clear head.

Bert, yep, Unleaded and IC. I've just taken off the IC and put the big injector in it. The injector will flow plenty for this setup.

Cam and springs would add 20Kw+ at 14 Psi, but at this stage its easier to go E85 and add Boost. Give me a few mins and ill let you know:)
