Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) 4/4 Sigma Throttle Bodies?

I’m back Richard 😉. Different moniker as I could never get my password sorted! Yes....I had my 2010 4/4 fitted with throttle bodies...by Aero Racing who at the time I think was the only option as the factory wouldn’t allow my dealer to fit the kit. In addition my car was modded to end up like Max 5’s car. Mike Duncan fitted the 4:1 diff, I fitted a panhard rod and Librands sports exhaust system, Williams did the front end Suplex kit and CR6ZZs. It was dyno’d at 156bhp. I also had the factory fit a Supersport style set of bonnets.....they cocked it up at first and that bonnet is on the Williams 4/4 race car as a result!
It was a lovely car and yes, I regretted selling it for the Roadster. It may not have had the performance of the Roadster but it was a lot more nimble handling wise and I didn’t have sump clearance worries. I should have swopped it for what I believe is the best 4/4....the 75th Anniversary model with the 2 litre Duratec.

It was rather iffy at MOT time, the 200 cell cat on the Librands system did it no favours and I was constantly getting the engine management light on due to lambda sensors giving spurious readings. I believe Williams have sorted that out for the new owner who loves the car.

On reflection I’d have gone down the route Kev and Craig did if it had been available at the time...the T/Bs certainly weren’t cheap. My best mod was the diff change to 4:1. It made 5th gear that more usable and helped acceleration. But I have to say the sound of the T/Bs was addictive when it came on cam!
