LOL@Guesswork, sounds like the GTR lot and their cams, esp with their "the bigger the turbo the longer the duration should be" ideas they have...
"Yea, i got a ropey 1980s 950bhp rated T88 truck turbo, huge ports, and 280deg 11mm lift cams, on a short stroke 2.6litre engine, it runs like a bag of laggy shit with no power under 6000rpm why? Will 320deg cams help? What about if i pay even more over the odds for parts, thats gotta help?"
