Spent an hour ruminating on where to locate the nitrous injectors. I wanted to hide them but that made it very difficult to maintain them.

I therefore think that the best place will be here. A bit of machining and tapping required but nothing too tricky. Can anyone see any issues with this location?

Change of mind.

More ruminating on nitrous injector location. Now thinking that direct into the trumpet in the plenum would work, be easier to do and keep pipes short. Looking for a freer flowing 90 deg 1/8 NPT union.

I think you will have a very entertaining car when you are done.
Enjoy.

Brass hex bar magically turned into three more nitrous jets. The bent one shows what happens when you fail to tighten the chuck.

For anyone still remotely interested :-)

Drilled and tapped plenum for nitrous injectors. All nitrous pipes are equal length, not essential but allows initial burst of nitrous to get to cylinders at the same time. One of those rare jobs that was easier and quicker than expected. The main reason being that the aluminium was thicker than I thought so I didn't need to get additional material welded on.

Thanks.

:-) It was born out of necessity. OEM dampers restricted wheel width.

A bit of bodywork today. Dry fitted exhaust shield and started on patterns for the ends in order to make it look less like a kit car exhaust :-)

Thanks, Glen. but it all only looks good from a distance. For example, it is fortunate that the tabs and nuts that I welded on are hidden :-)
