Is Cup Day this tuesday? and is it at sandown?

Yep! I'll find the detals on line somewhere and post it over in the events section.

Hi Peter,

A couple of things I noticed in the project - the water pump has a flat pulley being driven by the peaked side of the serpentine belt - could this be slipping and causing the higher temperatures?

Your carbies need a return spring on both throttles for the track - only the one by the side of the throttle cable is visible in the photos, so you may already have 2. Easier to fix now rather than at trackside.

Have enjoyed following your project

Nah, the water pump is spinning fine, this motor just runs about 10° hotter. It's a hybrid of stuff that was at hand, a design of convenience

. Compession is somewhere around 10:1 whereas the old motor was below 8.5:1. I've still got to tune it too. The waterpump doesn't load the belt much, it's much easier to rotate the pump than for the belt to slip.

I got some more miles on it today temperatures are steady, they're just a little higher than the old motor. It's in no way showing any signs of overheating

Each carb has it's own spring as well as the additional centrally mounted return spring that you can see in the photos. There's a total of three springs. The way it's set up any one of the springs will close all the throttles. I carry spare thottle springs to the track in any case.
If you're in Melbourne you can see it run out at Sandown on Cup day.

Thanks for the interest.

Is the compression only around 10:1 Pete?

I thought the 2E/AGG motors were already 10.2:1 or something similar??

Wouldn't the 1.8 head up the compression, due to smaller combustion chambers compared to the 2.0 head?

Probably, I was too lazy to measure it

It's certainly not 11:1 and it's more than the GX!

All ready for the race tomorrow.

The Dellortos mean that I can't use the factory breather setup so I had to make a CAMS compliant catch can.

Although there's plenty of off the shelf cans at autobarn for the rice brigade none of them are actually legal on a race track. CAMS requies catch cans to be at least 2.0L in capacity. Besides which they charge way too much for what is essentially a tin can.

Behold the budget catch can project.

I had all the fittings lying about,

The can itself was $10 who can guess what it is?
