I thought it strange that the TR5 in that article only claimed a 0-60 time
of 7.4 seconds - didn't really seem to justify all the cash spend on the
engine - not compared to the the 8.1 seconds of a stock PI TR5.
BTW other race specialists argue against the triple Webers - and suggest
fitting Lumenition or Weber EFI, which I've heard claimed outputs of 200bhp
at the flywheel.. but then you can probably buy a lot of carbs for #5000+ !!
