Cheers for that. I'm way down on the Mornington Peninsula. I meant there was no one to tune the custom turbo system which would need a specialist willing to do so, not just the Weber as such. I'd have thought twin 40s would be severe overkill for an n/a engine? Even if boosting, I was going to run just the single 32/36...
When I got my 510 it had a blow-through turbo into an SU into a custom manifold bolted to an L20. It definitely had a lot of power but the heat was a real problem, and all that fuel sloshing around in the manifold was a little unnerving.
You could probably argue that dual Weber DCOEs is overkill for the gains it can give, but one throat per cylinder will be better on the bottom end - not to mention it sounds epic
I guess it depends on what you want. The 510 I used to have had the dual Weber DCOEs feeding a tuned L20B (ported with high compression pistons, bigger valves etc) Electric Dizzy, custom exhaust and other modifications (thermo fans, electric water pump) had more than enough power for such a little car. It was so much fun to drive and it sounded amazing. I miss it every day!
Sounds a lot of fun. I wasn't impressed with performance of this in stock form. I'm shelving this project for now as it's a lot of work from here to get right. The worst thing is, this rebuilt engine that's going in I have no information about as it was purchased from the son of the builder. This means I have no idea the compression, why he decided to swap head off an L20B. It has no sump so I have to remove this old engine & use one off that so, again, long-winded stuff for now...
