[TR] Travel and tuning question

Tue Dec 6 02:12:10 MST 2022

Back in the day – like fifty plus years ago, all the larger UK car makers undertook extensive altitude testing on all their cars. Favourite locations were Europe, Scandinavia, Canadian Rockies, the Andes and Iran before the Shah was deposed. Lots of Pike’s Peak equivalent places in some of those locations and this sort of testing is something many enthusiasts don’t take on board.

Before the pandemic I drove my TR3 from sea level in California, to Flagstaff Arizona, just shy of 7000’, for Triumphest.  On the way home we drove over Tioga Pass going into Yosemite at 9,945 feet.  I didn’t adjust anything and it ran well.

Agreed. I don’t recall either of those Stags suffering fuel starvation or 'altitude' sickness. One on SU's, the other on Strombergs. Must admit I was glad when we did the descent as the altitude was doing me no good at all. That said, a great drive in both directions, a fine day and an amazing view at the summit.

I hear there are a lot of "'deer" on top of Pikes Peak at various times!

Thanks for the tip Randy! 
Yea, the trip to Pikes Peak started from a conversation with some TriState Triumph people at lunch after one of our “spirited drives”. The trip up Pikes Peak was a bucket list goal of one of the couples. I asked my wife if she wanted to go too and after saying yes, she suggested that since we will be out west why not see some other sites? We’re both retired so there’s no hurry getting back home. There’s about 8 of us going to Pikes Peak so far. I haven’t mentioned our extended trip to the group yet but some of them may want to go with us instead of driving straight back to Cinci.

Thanks again for the electric fuel pump idea!!
Tha car is already up on the QuckJack😁.

Sounds like a great trip - I didn’t make the last tour with my other FOG buddies but when they went through the Rockies the #1 issue at altitude was the mechanical fuel pump cavitating due to ethanol gas we think.  A couple guys on the trip hooked up temporary electric pumps and had no issue - no carb adjustments were made for any of them.

Hi all,
This coming summer my wife and I are planning a fairly long trip in my TR4A  leaving from Cincinnati, Ohio (altitude approximately 500’). Our first destination is going to be Colorado Springs, Co. to drive up Pikes Peak (altitude approximately 14,115’). Then north to Mt. Rushmore (altitude approximately 5,700’), then north to drive through Yellowstone national park (altitude approximately 9,200’). That’s going to be quite a swing in altitude and I am wondering if I will have to occasionally tune the SU HS-6 carbs? Has anyone on the list done a similar drive? If so, how did your Triumph run and what did you have to adjust?
Thanks in advance!
