1850 air box

[Maidstonerob]

Hi all did the 1850 ever have or does anyone run intake hoses on the air box.

Sorry if the subjects come up loads before but cant see anything on the forum

Good question Rob, I've always wondered why the 1850 doesn't have hoses but the 1850 and the 1500 do.

No, my 1850 doesn't have these air hoses either. I had a look in the parts catalogue and they are listed for the Sprint and 1500/HL, but nothing for the 1850. I can see the advantage in constant cold air being supplied to the carbs; I might have a look at fitting some.

No 1850's never had hoses. Sprints did and Spit 1500's did too so dolly 1500's may well have had them.

TR7's ended up with a flap valve to draw warm air from the exhaust, presumably needed to stop carb icing in the US.

Hi Tony,

Please keep us up to date if you fit some. I would be very interested in any changes in behaviour of the engine.

When I had a Sprint, I took the hoses off and noticed no difference at all.

Aye, I know that some folk have done this on T2500S models to stop them stalling at junctions during the winter.
Didn't other BL cars of the late TR7 era have summer/winter air cleaner settings, eg the Ambassador? (By the way, late US spec TR7s had fuel injection.)
