I took a long hard look at the TWM induction Throttle body replacements
for SU's (and the like) a couple of years ago and discovered that before
I was finished, I would have over 2 grand invested in a twin TB setup
for a Spitfire engine. I decided the money was best spend elsewhere.
In checking back later, I had someone at TWM tell me that the SU
replacement throttle bodies were dropped due to "Lack of interest". At
2 Grand, I can see why!
