Jonathan_bell Posted April 25, 2015 Report Share Posted April 25, 2015 Hello, Does anyone have a Triumphtune TT1200 6:2 manifold, reading the Triumphtune catalogue it states you need a spacer to be fitted to clear the PI throttle bodies TT9220, I can't find any details of the spacer anywhere.

JohnC Posted April 28, 2015 Report Share Posted April 28, 2015 I had a TT1200 manifold and didn't need a spacer. FWIW I have a 1971 car, in case that makes a difference. BTW I removed said manifold a few years ago and replaced with the original cast iron model. Much flatter torque curve and hence much, much less peaky power curve. I think I have comparative dyno tests somewhere if you want to see them. TT1200 may be a good manifold for the track, where you expect to be up near the red line most of the time (so I understand; I have little track experience), but not on the road. IMHO. Disclaimer: I have a fairly hairy cam (please don't ask) which may exacerbate the peakiness for my car. Cheers, JC Quote Link to post Share on other sites
