2002 Superformance S1 - Lotus Super Seven Replica
Car number 30 (of 56 built)
Self-designed and self-built Ford Zetec, 4-cyl, 2.0L. I designed it to be a high-strung engine, and it is: 8500rpm redline, 11:1 compression, 220-230hp (soon to be dyno proven), and a rough idle
. With only about 1420lb to push around, that's a ton of power! Here are the basics:
- started with Focus SVT block
- lots of custom head, valve, and cam work (all of which are essentially one-off... not much available for the SVT engines)
- custom 4-2-1 header
- custom intake system tuned for high rpm (runner length, plenum volume, etc.) with a 70mm throttle body
- MegaSquirt II v3.57
- KnockSenseMS with Ford knock sensor
- Innovate LC-1 WBO2 setup
- factory Ford coilpacks
It has been up and running since 1/19/08. I'm in the final stages of tuning now - it's running great! The hardest part, of course, is the low rpm stuff with the lumpy cam. As I figure out more tuning tricks, it's getting better and better - with the exception of idle (which will *never* be perfect), it's quite smooth.
Of course, from 4000-8500rpm, it's a complete beast! And MegaSquirt makes it all work like a charm...
If you have a similar setup, feel free to write to me for tips on setting it up. Also, if your curious about more details on the engine build, let me know. I'll have to post pics here at some point...
