But when the price jumped up almost 100% I really couldn't justify it.

Our new garage is about halfway between Oslo and Gardermoen, so I thought I should drive the car to SCC the first year it'll race..  Roll Eyes I think it's about 25km, so doable  Grin


Does anyone have a good tip about brakes? The car already have discs on all four corners, but 4x130 rotors. Money wise I should just buy new rotors in chevy PCD. 10,22 on EMPI brakes was no problem, so a second faster shouldn't be a big problem?  Shocked  Grin

No car in the garage, so tore the engine for a checkup.

So far so good!

I can see a car in the garage Cheesy 

Hard to tell on plugs as looks like they done a few passes? but timing mark looks quite far down strap

On the ground strap, if you do a pass on new plugs and check them after[ mustnt drive car back though, shut it off straight after pass] you will see a ring on strap, around the bend area or slightly before seems to be ideal on alcohol based fuels

Ok, i believe I’ve got around 20° timing at 32-33 psi.

I’ve also spent some time to figure out the angles to mount the coil overs at.

At level axles (0° camber) they will be angled 20° inwards to the middle of the car, and 90° to the upper ladder bar tube.

This will aid the coil overs to not loose wheel rate (spring rate measured at the wheel).

If you mount them straight up, they will get a wrong angle due to the arching of the swingaxle, and get less and less wheel rate as the wheel travels up.

Now the wheel rate should get higher as the car squats more and more.

Yup, the new style.

67cc chambers, 1,2mm deck and 8,2-1 I think.

Haven’t touched the heads.

Are you using only the stock dh oil cooler or do you have an extrenal also? , and does your oil temp stay cool with that?

Stock and an Atoimic cooler also. I might skip the DH cooler. The engine will be 3" higher in the new car, and I think I'll need to be able to remove the shroud by just pivoting it out.

Oil temps are manageable  Grin

Tore the rest of the engine last night, rod bearings are shite and mains may work again.

I'll change the oil pump as it finally got some nicks in it.

Solution: Dry sump. Check out TP pump. Very good stuff.
CB is more affordable but needs massaging and has some questions marks.
Pauter, Autocraft are jewels but are probably overkill for most applications.

I've thought the same thought.. However I've never had any oil pressure problem.

I believe this may be a crank issue? The crank only has 1 oil port per rod, and consequently the rod bearing needs to drag the oil 1 round, before being oiled on the same spot?

Looks like oil contamination from E85 & maybe some aeration of oil to me, center main looks pretty good for all the abuse it gets, also oil pressure like boost pressure is only a measure of resistance, its flow the bearings really need, thick cold oil gives lots of pressure but no flow which is why we pre heat oil Smiley

I never drive it before the oil is hot. But yeah, I admit to using thick oil  Grin

Maybe I should start to get parts for a dry sump system after all..

I used plenty of both, never seen any real evidence of either being better or worse, more important to make sure oil holes line up and bearing is decent quality material

You need to use a better oil, Ester base handles E85 very well, gives a stronger oil film and hangs on to metal longer. It`s all about when the oil film gives up Wink

I'm sure oil plays it’s part also!

I’ll clean the case and internals up good and slap new bearings in it. Might do a dry sump, if the money is right..



I only need a few bits and bobs on the engine this year, so quite pleased!

While the car is in Sweden, the engine in pieces, and the transmission in plastic waiting to get re-sealed, I'm thinking about making the new exhaust  Grin

I think I need a new header, as the "CB-style" I have will interfere with everything.. Tubo will hit the rear valance at the minimum.




That said, I also need to make new plenums, or at least redo the ones I have. They will be too tall, at least the entrance pipes into the plenums.

[ Attachment: You are not allowed to view attachments ]

I was hoping to not have to cut away the "roof" below the window inside the engine room.


Looking at old pictures, I'm hoping I can use the intake/TBs at all..
