Well, that was fun! One less yellow flag or a few more ponies and he might have gotten 2nd. Still, he was on the podium. Apparently a 40 year old Lotus 7 w/a 1600 cc carbureted engine? Any idea what approx engine power was? Loved the blinking shift light. What a track, tons of elevation changes and huge straights.

Kent block, dog box, and clamshells...Impressive!

:hurray:

I know what a Kent block is and what clamshells are. What is a dog box?

[bsimon]

A dog box is a transmission with no balk ring syncronizers. The hub faces have simple dogs that engage with the gear sets. This allows the fast clutchless shifts you see in the video. In septic vernacular, they're sometimes called crash boxes.

Wow, Learned something today. Eric's engine is the 1500 pre-crossflow! Checked specs for the class...the series 4 car is allowed the crossflow but the S3 cars max allowed displacement is 1503 cc. That and a required weight with driver of 1530#. Exceeding the gvwr, I think.

 

No clue what a full built, no expense spared, 1500 can make with stock valves, a pair of DCOEs w/ 30mm chokes. 160?, maybe a bit more....

 

What an impressive drive that was. Loved the sound of that engine in the video. It was really singing.

Yikes, pre-Crossflow, and up against DOHV Miata engines, and VTEC Hondas! He was really haulin butt, whatever it was.

 

What engine do the E-Production Sevens run?

Zetec. Contour/Mystique. The base Caterham engine delivered from 1999 to the Duratec. Valve lift limited to .380", 10:1 compression max. Unlimited ECU. Stock Sierra 5-speed.

 

But we do get a special dispensation, we can run pump fuel, 87 from Sheetz...or who...ever....
