PatK Posted January 24, 2020 Report Share Posted January 24, 2020 At long last Pete I have finally ditched the oversize SU HS6s and managed to locate a Vitesse 2L Mk2 inlet manifold. Cleaned it up with a new Banjo bolt and stainless 3 way water channel, plus a kind member managed to find a correct pair of 150 CDS carbs. Completely overhauled them with a Burlen kit and now the Vitesse is running and idling so smoothly and the choke works correctly too. So you were right Pete those SUs were wrong for the car and overfuelling it. So a big thanks Pete and especially to please you I have removed Satan's oil feed to the rockers! Now all that remains is for someone to identify the manifold that the twin Su HS6s were on, shown in photo 2 below. I think that the blanking plug has been fitted because the vent from the rocker cover was fed straight to each carb and no brake servo was needed on the Vitesse. Is it a Triumph 2000, 2500, or TR ?

Pete Lewis Posted January 24, 2020 Report Share Posted January 24, 2020 Pat youre too kind ,its how i felt on a drive including the shot gearbox Im pleased its how Triumph intended , and performs better than the supposed upgrade ......had a local car thats been through the same as youres. its also much smoother and better all round its another one of the Must haves that cause chaos to many twiddlers now I have got this orrible thought to make a bid and make my 2000 (HS4 ) into the TC spec which used HS6 seeing as you have the 6s but not the angled manifold Ha!!! ( phew Im saved ) but i dont have the get up and go just yet and the orrible 4s do seem ok , it will never set a record for anything , but gets there pretty well on song.

PatK Posted January 25, 2020 Author Report Share Posted January 25, 2020 Thanks Pete, so what car do you think that this manifold is off, its not angled, could it be for a TR or 2500? It also looks as if the intake ports have been gas flowed. Cheers Pat Link to comment Share on other sites More sharing options...
RogerH Posted January 25, 2020 Report Share Posted January 25, 2020 Hi Pat, the manifold is not off a TR2 -6. They do not have the water heating system like that. roger Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 25, 2020 Report Share Posted January 25, 2020 2500pi 2500S engine is angled same as 2000 2000TC , TR6 on carbs were generally on strombergs its what had 6pots and HS6 and upright or has the face been re machined ????

Pete Lewis Posted January 26, 2020 Report Share Posted January 26, 2020 sounds a bit of a hybrid not many upright 6 pots on HS6 TR5 /250 had strombergs 175CD with 4 studs about as close as i can see Pete Link to comment Share on other sites More sharing options...
NonMember Posted January 26, 2020 Report Share Posted January 26, 2020 Are the HS6 holes on the same PCD as the 175CD? I know the HS4 and 150CD are different but I don't know whether you can put SUs on a TR250 manifold. Link to comment Share on other sites More sharing options...

Back again; this is the only photo I could find, from Rimmers' site: Hard to tell from that angle but it looks close to the one in the photo further up.

Thanks Colin, it does look similar, except the one I have only has two stud holes and the SUs were only attached by the 2 studs despite having 4 stud holes.

I don't know what the PCD is on the Stromberg 175, CD, but if it only has 2 studs to attach it like the 150CD, then this manifold could be for 175 CDs. Thanks.

Thanks. Pat I think the 175CD have four studs but that manifold is clearly designed for a four stud fitting, it just looks to be missing some studs.

Pete Hi Pete, why does the intake manifold need to be angled upwards on the 2000, won't a parallel intake face and carb face work? Checked it recently and it is only angled upwards by approx 4 degrees. Thanks Pete. Pat Link to comment Share on other sites More sharing options...

True, but only 2 stud holes have been drilled and tapped on it, its all a bit of a mystery. Thanks. Pat Link to comment Share on other sites More sharing options...
