Williams vs Megan engine build

[Evogone]

If you were going to get one or the other engine for a full engine rebuild ITBs 200 plus hp which would it be and why ??

[Justin..]

megane F7R 714

because


chain driven pump, bigger flywheel for bigger clutch and the flywheel has a better trigger pattern for aftermarket management, engine is more likely to be found and more likely to be cheaper

[Justin..]

chain driven oil pump i meant

You told us you dont need ITBs for 200 bhp+?

Headwork and cams you said.

Changed your mind then?

I thought you might.

714 because the crank is forged steel and thus lighter, total weight saving of the 714 is 16kg iirc.

200bhp is possible on standard cams and standard inlet for cheap. I'll prove it. I would definately say a 714 bottom end will help though.

Define cheap and proof on an engine dyno not a rolling road please. :D

well my engine is already 150lb/ft and 180bhp with minimal work, so I only need to improve that by 20bhp

I won't be putting it on an engine dyno (to expensive), so it'll have to be a rolling road.

cheap? not sure really, much cheaper than a turbo or itb's... hundreds rather than thousands.

BTW I think you know it's possible and I know you know what I have in mind

Rihcy thinks Meggy.

The cranks from either are cast, not forged.

Either will/do yield good results, but as with anything it depends hugely on the quality of workmanship.

Either engine will give 200+bhp with a moderate set-up.
