In a conversation with a tuning expert recently, and in trying to research what period tuning mods allowable to tweak my Classic Road rally car - I was advised that the Inlet manifld should really be replaced with a Triumph
2000 inlet manifold!?.. as this will permit the improvements in breathing necessary. This was suggested as being the beginning of the tuning improvements.Bonnet clearance is a concern, as is passing eligibility scrutineering - what experiences and or solutions can readers offer in this respect. Kas Kastners Competition Manual suggests modifications only to the existing manifold. What alternatives are there.
I would appreciate answers to this particular question - but will also be happy to hear from anyone with experience of a thorough tune for a MKII GT6. I am aware of the usual simple mods to Carburation ( running HS4's) K&N's and 6-3-1 vs 6-2-1 exhaust manifolds but wonder also if anyone has experience of the relative merits of Twin vs single exhaust ???
