Race Engines-Uni Project

[colin4696]

Hi guys I have been set a uni project in which I have to design/improve a beathing system (intake and exhaust) for a race engine. I need to choose an engine on which to apply the design.

Just woundered if anyone could suggest an engine? Basically its needs to be used in a race series (preferably many) and there must be information/drawings/figures available for it so I can obtain the details/dimensions.

Thanks

Colin

PS links/websites would be a great help

Do you have any guidelines - maximum capacity or whatever?

Ford Pinto 2.0 SOHC have a lot of potential and they are easy to obtain from scrappers, original or modified parts are easy to get and there is a considerable history of success in tuning them. The 1.6 version is pretty good too.

Pinto engine is a good option,

the rover k-series, 1800cc is the most common displacement.

rover V8. You should be able to find plenty of techincal data for that one. Its been around longer than you have (assuming you're not a 'mature' student).

The hemi small/large block chevy v8, the yanks love that one, theres even a thread about it in general gassing atm.

Best not look at anything too modern/advanced. For instance, the 2000cc lumps found in subaru's and evo's will be difficult to redesign to improve breathing any further.

Also, as a uni student you will probably be well versed in taking 'inspiration' from others, so looking at what after market specialist tuning companies provide for the above engines will make your life much easier.

Rover V8...used in loads of series...can give you loads of info, and a workbench to try your plans out..and probably a base engine to run on a dyno...the Achillies heal has always been the air flow restrictions in the head. Contact me through my profile, as an ex-Automotive Engineering student i know how ****ing difficult it is to get help with things like this

Perhaps a project such as this would be ideally suited to a Formula Student entry, looking at one of the many 600cc engines out there - and a lot of R&D work will have already been done for you to build on.

A-Series out of Mini/Metro, also large tuning potential, cheap to get your hands on, common and easy to work on.

If you wished to push it far going to design an 8-port head, possibly with OHC or DOHC and 16v.

Yeah, I agree, it isn't too difficult to get a rough cast head up and running. There is loads of literature and that would be an ambitious project. I have patterns for an 8 port which I am waiting to get cast up (in iron). If you have any questions, the A series is probably the best idea, plus, when you have finished it, it will sell for a fortune on ebay. I'm up with my engine science, re A Series and would be interested in hearing about your ideas.

A good development would be to design a supercharger head and cam, how would you alter the chamber, ports, valve sizes, cam? I have thought about this lots and am armed with the theory (as well as a broken engine).

You could also get the lump dynoed static and then again after, the difference would be large, plus aftermarket stuff is cheap. Besides, it will give you an excuse to buy a mini if you don't have one.

PS: BMW cooper s superchargers go for about £100 ON EBAY!!!
