Triumph GT6 vintage race car part 3 - fifteen years later 

Yea, it all got to be too much for me with all the other automotive interests I have - I was spread too thin, racing takes a lot. However I am planning to resurrect my street GT6+ with a performance engine, just not to this extreme. I learned a lot building this car and I will apply it to that project. Thanks for watching.

Also notice that the external oil line to the rear of the head has been removed. Deemed unnecessary due to the increased oil pressure, we will see how that works out.

Yes, the swing axle GT6s can be handful. Triumph fixed that with the MK2 rotoflex suspension, but then for some strange reason ($) reverted to swing axle with the late MK3. This race car has two U-joints and a slider in the half shafts to replace the rotoflex.

SL are fab, but a GT6 is definitely more fun, particularly on a Sunday morning

Greeting Texas! I've seen some very fast Spitfires in my time, on some tracks quicker than much more powerful cars. The oiling system is very simple: it taps pressure directly after the oil pump and feeds it into the main oil gallery right beside each of the main bearings farther away. The main oil gallery is left intact as well. People say this prevents pressure drop in the bearings far away from the oil pump, essentially equalizing pressure in the main oil gallery. If the oil gallery were large enough in diameter it would not be necessary, nor desirable, to have all these extra lines.

The diff in this car is welded, other than that it is stock. No problems so far. The GT6 sun gears are definitely a weak point, but that problem goes away when welded. Even though they are identical it is important to never reverse the stub axle sides when disassembling an old rear end. It may sound like an "old wives tale", but doing this is considered a cardinal sin among race mechanics that I've talked to. The grain structure of the metal takes a set over many years and may even twist a little, if you reverse the main torque load they will snap!

It serves as a heat shield from the headers underneath, also if there is a fuel leak it keeps the fuel from leaking directly onto the headers. Mostly it is a heat shield. I don't think they have a youtube channel

@@Porsche9elfer Thanks, makes sense.

It is from a VW Sirocco. See the part 1 video from 15 years ago for more details. We have never had overheating even racing at 95F like in this video weekend. Also there is an oil cooler. Sometimes just having a new or completely cleaned out GT6 radiator will solve overheating. My street GT6 used to always overheat until I had a new core put in the original radiator. Your performance cam will not add much to overheating unless you are pushing the car hard.
