Best of luck with finishing all off and Driving it Colin NZ RE: bantam turbo - Edgar Lowe - 01-03-2019 Hi Steve Great job would love to see pictures of the whole car.

Adjustable timing gear made from 2 gears , cut inner center half out of one so leaving step on outer edge , for second gear cut outer half with opposite step to fit first one , drill / tap 3 places with adjustment slot for screws/bolts . Mark as desired for advance ( lower rpm power ) and retard for (upper rpm power) .. Electric oil pump from racing rear end (differential) , look under Nascar used parts , makes 50 psi. , pump to circulate oil for cooling .. Tap sump for intake oil , outgoing oil to wherever you want , one way check valve at pressure side . I have gear internal pump , and ali. sump . I have Hadley crank with timing cover to filter oil and put oil to front of crank . Oiling system also supplies oil to lifter/follower side cover and cam center bushing from outside crankcase.

Amazing project. ![]() RE: bantam turbo - Hedd_Jones - 01-03-2019 anyone running a book to see how long it takes to spit the block off the crankcase? RE: bantam turbo - Zetomagneto - 01-03-2019 I must admit to having the same thoughts.l obviously wouldn’t wish ill on this project and hope that with all the developments gone into this that retention of the block will have been addressed. This is a very expensive engine, I would hate to see it end in tears. It is certainly unusual to see an Austin Seven engine used in drag racing, I can’t help but ask why? but the rest of might learn something from it. RE: bantam turbo - Colin Reed - 01-03-2019 Hi Zeto, A lot of people derive pleasure from the technical side of things making something work better mixing different components from different times. Also if something goes Bank when pushing the boundary it's just back to the drawing board. And that is also just part of development it can be costly there have been a lot standard engines go Bank Just enjoy working on your Austin the way that gives a person the most pleasure we are all different Colin NZ RE: bantam turbo - stuartu - 01-03-2019 History would suggest that with circa 5lb turbo boost (according to the previous thread) the block will probably stay on the crankcase for as long as Steve needs it to. I would think a critical factor might be RPM. I presume final drive ratios for runs on salt with (as I understand it) a run up to give a flying start would be rather higher than one might use for drag racing but no doubt Steve will enlighten me. An intriguing project and interesting to see. Regards, Stuart RE: bantam turbo - Zetomagneto - 01-03-2019 Colin, I am not decrying what is being done.I too enjoy engineering challenges, I am currently supercharging a Fiat twincam engine in my Morgan.Nothing is available off the shelf, I have fabricated pulleys, tensioner, Brackets, manifold, plenum, air to water intercooler, , a Morgan engine bay is very narrow , that in itself has made it more difficult.If I thought this wouldn't work or was going to blow up I wouldn't do it.I have a fair idea of the work involved in the Bantam |
