Wreck to Race.

that sounds....... EROTIC !

[Preen59]

Sounds almost as good as a 16v....

Very nice. Gotta love the gasping induction note when the engine is cold and you rap the throttle.. It sounds like the engine is gasping for air. (When in reality, it's the opposite, haha).

[Jarred]

Oh that sound!!

hopefully I can make it to your next track meet, even if only to hear that sound!!

Got it all together today and took it out for a run about.

Bucket loads of torque, really repsonsive throttle. It will break traction mid corner if you're carrying enough revs. Quite amusing really to steer it with the throttle mid corner, it's been a while since I could do that.

The light flywheel means you need a few extra revs on board to get it moving without stalling.

It's still untuned, I'm going to balance the carbs tomorrow and see how much static advance I can dial in, no sign of any pinging today.

Being the longer stroke, it's not as willing to rev as the 1800s but I don't think it needs to. The power is all there to be had below 6000rpm.

I might do a bit of experimentation tommorrow with cam timing and shift points.

It does run hotter than the GX, the only thing I can put it down to is the higher compression. The cooling system seems to handle it though.

I'm not thrilled about the oil pressure, seems to be lower than I'd expect. The oil I put in is a synthetic Fuchs 10w-40, I think I'll go for something heavier. Might have to investigate a new oil pump too.

At this stage I'm going to give it the green light to hit the track on Cup Day for the Group 5 sprints. Any volunteers for pit crew?

And yes - it's loud. Nothing stopping me from picking a bigger cam now although this setup seems pretty tractable as it is, a bigger cam might push the power too far up the rpm range for the 2.0

Good to hear it's all running well.

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?

Pete

[Jarred]

an tin cylinder??

am i right??

[Spyda]

Everyone knows.......its a Pringles can.

[Peter Jones]

Both wrong, it's stainless steel and it came from Big W.
