Hamish Posted August 19, 2021 Share Posted August 19, 2021 After working on the suspension for a couple of years to try and gain an edge ( a firm believe of suspension thus handling first )whilst staying in the same power/weight/limited mods road going class (116bhp = less than 130bhp/tonne) I decided that despite going up a class (130/T to 180/T) thus more challenging target times, a more powerful engine would be the way to go. not having your skills I have got some professionals to help out. It’s been a 7 /8 month build (making good use of a bit of a legacy after dad died - he would I’m sure approve- as many of you will have picked up he was a life long old car fanatic) so pictures are the order of the day.

Nick Jones Posted August 19, 2021 Share Posted August 19, 2021 Anticipated torque/power? Torque is the more useful on hills. Preferably a big fat lump of it over a widevrev range…. Link to comment Share on other sites More sharing options...

This looks like it means serious business! I couldn’t afford a whole one. !! but does mean it’ll be quite quick to respond both on and off the throttle. just hope it ticks over. The current one is original but machined to just under 20lb There should be a pair of 45 dcoe’s being fitted to feed the engine. Link to comment Share on other sites More sharing options...

michaeljf Posted September 12, 2021 Share Posted September 12, 2021 Hello Hamish, I like the "flick book",and the motor. My friend that I go pit crew for is still running SU's (2x2inch) and points and 2.1 L for the rules for group SA production sports cars and his TR3A on the dyno is producing 147 hp at the wheels and road registered. Will be interested to continue watching your progress. Regards, Michael. 1 Link to comment Share on other sites More sharing options...
Hamish Posted December 9, 2021 Author Share Posted December 9, 2021 It’s getting exciting now as it’s all going together. I did a deal with the engine builder that they would fit it and run in the cam and due to personal logistics they will now put the first few hundred miles for the price of the fuel then do the head tightening - tappet adjustments etc. then I can get some proper running in miles on it before competition abuse next year. Whilst I had dearly wanted to do the driving to get it bedded in - family commitments in Devon comes first, at least this way they can’t claim it was done wrong ! 1 Link to comment Share on other sites More sharing options...

You do realise that we expect you to be quicker next season don't you Ha ha I think you will be right nick. It won’t be a small racing fuel tank in the boot but a bowser trailer!! I HAVE to be quicker just to get the same points as the bogey times will be tougher in the next class. I’m moving from 2a to 2b https://www.tr-register.co.uk/uploads/2021/02/18/The-Revington-TR-bogeys-rev-21.1.pdf But I did better the 2a class times at curborough, 3 sisters, loton park this year. you all need to keep your fingers crossed.

MilesA Posted December 15, 2021 Share Posted December 15, 2021 Looking pretty serious Hamish. Now you've got those Webers, welcome to the 17 MPG Club! Out of interest, which ones are they and what size choke are you using? Your photos reminded me that I've been meaning to fit a second cable to mine but that has dropped off the 'to do' list. A simple Christmas task I hope. Miles Link to comment Share on other sites More sharing options...
