Cosworth YB Turbo Into Elan

[stevebroad]

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?

[stevebroad]

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.

Plenum nitrous injector, one down and three to go.

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.

Very interested.looks an amazing project.
Im particulary interested in your rear end..!!

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

Steve, every time I think I have good mechanical skills you put me to shame. I do enjoy your work! Keep it up.

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

Well, that was almost an unmitigated disaster.

Easy bit - Mould came off the car fairly easily and fitting 2 layers of prepreg was a breeze. Wrapped up, vacuumed and cured at 120 deg C for an hour.

curse word bit - Getting carbon out of the mould was a nightmare, should have taken a few minutes but took me over an hour. No idea why, mould was prepared properly and had 8 coats of release agent. Had to get heavy handed and it is just as well that I hadn't planned to make multiple parts with the mould as the gel coat is destroyed. Also fortunate that I paint my carbon as the surface is f**k*d.

But at least it seems to fit pretty well. Once it is trimmed it will be fine, honest!

Hopefully the smaller front cap will be easier.

Steering wheel finally finished. All wires in connecting cable used up and no room for any more switches anyway

Screen contains all road legal warning lights plus speedo and tacho along with outputs from the numerous engine sensors. Switches are for the linelock, launch and traction control, nitrous activation (illuminated), ECU map strategy options, parachute (with keyed activation and warning lamp), fire extinguisher, gearbox neutral and indicators. The four black buttons control the various screen pages.
