You need to start a thread on how the 420R, 620S, and CSR 260 compare on track. #peerpressure

 

Its not exactly a 620 despite the label.  Actually a 700S.....   #faaaaaarkitsquick  #gripchallenged

The Duratec pump is on the crannkshaft llike a Zetec?  I did not know that.

 

I don't remember an engine with a belt-driven oil pump, just water pumps.

 

The oil pump on my Caterham 1700 was driven by a shaft, presumably  driven off the camshaft.  I'm told tht the Lotus-Ford Twin Cam still has the camshaft in the block, only there to run the oil pump (and distributor?)

Taken Sunday at the autocross.

When I drove in on Saturday, some wags in the club asked me if the car was for sale.  Really original humor.

 

I said yes, but I didn't tell them why.  I only said that I had not driven to California for the scenery.

 

This was a good Seven to bring to a novice school:  It has ordinary 3-point belts so students did not have to mess about with more-exotic restraints.  I generally don't beat all the students at these things, but this time I did.  I was trying harder because of the cycled-out tires. 

 

Practice event Saturday, so I plan to spring the orange beast on them.  The tires are not legal for XU, but fortunately, the practice day is a classless event.

 

I wound up second of three in XU on Sunday.  I want to sell this car so it needs to look more-impressive next Sunday.  When I got home ordered 4 fresh Yoko 052 tires from Tire Rack.  They are in-stock at their Roseville warehouse.  I pick them up Tuesday.

And the mechanical fuel pump, should it be so equipped.

It's not. The pump is chain driven off the crank

Ah.  So the oil pump is immune to the clutch-limit disaster.  It would be the thrust washer itself that would take the hit.

 

I wonder how unusual the Zetec is for its oil-pump placement.

The mirror clamps on the CSR's SLR cage would shred the Storm Cap that arrived today from Soft Bits For Sevens.

On Long Island, The North Shore has land on the south and water on the north.

 

In Minnesota, The North Shore has water on the south and land on the north.
