A little update.
The car is booked in for cage fitting in mid January, and I've penciled in the idea of a track day at Bedford Autodrome on the 22nd March. I was nervous just considering it. I've had the car 8 years and been doing this latest major project nearly 4 years, the thought of.... well the unthinkable happening is terrifying, but this was always the end goal so here goes
I was working through the list last night and got to the point where there was nothing left to do but change the gearbox (something I've been putting off).
The current GB works, but is the R28, with an apparent oil leak under hard acceleration and a gear linkage problem. I've got the stronger R30 to fit (I wanted this done in time for the track day) and with a fully working gear linkage.
So I studied the new gearbox to try and understand the oil leak problem and its become apparent that it's not a "leak" really. In the Scim the acceleration is rather more rapid than in an Omega and the oil swills to the back of the box, so much so that it poors out of the breather (which is right at the back, see photos). Great design that! Thing is it only happens when the box is more than 45 degrees which must mean the Scim is pulling more than 1G in acceleration in 1st gear!!!
I did a few calcs based on the 0-60 being 5.5s or less and it might very well be pulling more than 1G in 1st gear.... cool!!!
But annoying for the gearbox "leak"
Anyway, here is the fix I've come up with. It saves drilling and getting swarf in the box. It's not ideal but certainly can't make it worse, and it might even work a bit
(I'll bee keeping an eye on the oil level)
With the breather extended forward so much it can pull 80G and won't poor out.
After faffing around with that a bit I only got as far as taking the prop off and gearbox mount, so more to come on the gear box change.
