same capacity dd, any pics Simon? also will the quads help reversion exhaust reversion with those larger valves ports and exxy tubing or do you think the limits are already reached with this cam, turbo, capacity vs rpm limits? whats`s your opinion?

1179cc?

Ive had a few problems getting the new manifold working properly.

I made it with the injectors mounted out near the ends of the runners. when i tried to tune it, it was nearly impossable to get the fueling right until the air speed was high enough (about 2500-3000 rpm). I pulled it off again and mounted a second set of injectors pointed at the back of the valves.
The primary injectors run at low speeds and loads and the secondary injectors are phased in as the load and revs come up. Seems to be fairly seemless.
End result wasnt much better than the other manifolds. Its a little better at a couple of points and worse in others.

Well done Simon the single to quad concept sounds like a very well thought out plan and has us in great anticipation. I hope it makes more under the graph in all areas and more hp with the porting and bigger valves (exhaust valves as well?).

Pics please!! Can't wait to see what it does! See if you can get some video, would be music to my ears to listen to it at WOT

Finally finished the new inlet manifold.
It`s made it so i can swap from the single throttle to quads easily. Ive also moved the injectors out to the start of the runners and made it a little shorter than the last one.
I`ll be disapointed if there is no Hp improvement after all the hours spent on this and the new exhaust manifold. I`ll run it up tomorrow all going well and post the results and some pics.

Simon absolutely love this setup, so spewing I missed the sale of the injection setup would have loved it for my wagon.. Will be keeping a close eye on your next setup.

Cheers graeme

Nice work on the magazine article mate I will have to track myself down a copy

"Mad pushrod 1179cc" should be the title :)

Its not that much of an amazing turbo datsun.....all a12s make around 170kw dont they

So isnt there a twin head and some cooler manifolds kicking aroumd for it somewhere, coz they would probably make it amazing
