Supercharged Austin seven engine advice

I'm with Malcolm.
And if I wasn't I'd be with Ruairidh!

I'm with Malcolm as well - or I will be in about an hour!!

Seriously, what he says is correct. A blown engine as your first foray into Sevens is much too great a step. Also, if the car is intended for competition, check the rules and regulations before you start your build.

First off work out what you want to do with your Seven. Bert Hadley hill climbs, 750 Club racing or VSCC events and ensure that your dream fits the rules. You wouldn't believe how many people feel the world is against them when they didn't read the eligibility rule book first.
A single seater may be attractive but it's a whole lot harder to get set up and running well when you can't take it on the road for a blast.
Blown cars are really great fun but as almost everyone has said, start unblown. If you know where you want to end up competition wise it may alter what you start with. As an example if you want to end up with a Cozette blown VSCC type car start with a magneto engine - it'll make the upgrade to blown easier.

Amen to that!

generally it's those who have read the rules you need to worry about

To give you an idea of cost there was a supercharged engine on eBay at £18000 if you do the maths that's a reasonable price.

I think my question got lost above Zeto.

Genuinely interested in the breakdown of costings, please.

Rough parts list and prices for a blown Ulster engine. No labour costs or external machine shop (boring, lightening etc) costs. Worth remembering that if anyone thinks that they can pay much less an hour to a specialist to do this type of work that they pay a mechanic to service their Mondeo they may be living in the past. I've spent most of the Christmas holidays putting together a blown engine from a bare crankcase and the hours don't half rack up. 

Yes, open to criticism and you could shave a grand or so off if you tried. Of course anyone from Yorkshire could almost certainly do it for half the price!

Thank you Charles - very interesting. The front is the largest cost by far.

Did the one on eBay sell?

In the "front" there is, of course, a lot going on; steel gears, oil feed assembly, water pump and so on. Having machined the lot myself it's not a simple weekend task.

Is the cost above just for the castings?
