Well after a long journey which started in Dec 10 and a few time set backs, My 2.7L TR6 engine project is coming to completion, I will be traveling to NY next week with trailer in tow to pick up my engine. The Crankshaft lightening, nitriding and balancing took an extra 6 weeks that were not planned for, and a fouled up cam shaft bearing last week pushed the delivery but only 3 more days. so stay tuned! Pics and dyno results coming,

Well done Hondo. I know you have been waiting a long time.
How did the tranny turn out?? Good I hope.


Wayne
 
Looking forward to seeing it in the car, as well as along the way. Good luck with everything.
 
HI Wayne,
well the tranny was in pretty good shape, the layshft was replaced all the syncros plus all the upgrades were done, the OD was in great shape and a new uprated cone clutch was installed, I am looking forward to getting to use the OD 4 Days to pick up!

Hondo
 
Hondo, Glad to hear all is going well and you seem to be getting all you wanted in the performance part.
Your car will look awesome. Don't get in a hurry and scratch any of the finished parts.
Wish I could help, but Doc won't let me lift over 10 pounds for another month.

hey Wayne, you get better, I will be back on Sat and then Sun I have to fly to Fresno for some manufacturer I rep for training, big waste, but I didnt say that. then next weekend I will start putting it back together, since its so hot I will be taking my time

Good point, prolly should have been first. Without that the rest is moot
 
Made it to Hagerstown md. Another 6 hours to cananduaga NY tomorrow. Staying at the
Inn on the lake for 2 days to meet with a company I rep. Powerhouse
Technology. Did make a 80k sale today before I left town. Eating at a great little Italian
Restaurant right now. More pics later I am on my iphone
 
its Marios in Chambersburg PA.
I made it to Canandaigua NY, meetings today/work, tomorrow Dyno Day! more pics later

well dyno day is over engine is safely home and here are the results, after messing with the triple webers seems the calculations were off and they ran lean but after switching out some jets we got it running in the 11-12 range for breaking in the cam then we did several pulls 4000, 4500,5000,5500
the torque was 182 foot pounds and the HP was 182, we were going to pull at 6000 and 6500 but seems the crmoly push rods couldnt handle the revs and started getting valve float, as a note Kai didnt supply the push rods, the HP was still climbing at 5500 and Kai thinks we could have got close to 200HP, I am getting a set of Kai's CrMoly pushrods at .083 thick. He feel very confident I can push his engine to 6500 rpm,

Here is the builder of my engine and transmission and OD
Kai at Wishbone classics,in Carmillus NY I am very impressed with him and his knowledge of British engines! You want all you can get! call Kai

I am beat since I drove thru the night but I will get some pics and a link to the video
I cant wait to get this monster on the road

180 ft lbs is a lot of torque in a TR-6. You must be very happy with those numbers. Heck, I always though 150 or so would be a good number to strive for!

Nice job, keep the shiny side up. :thumbsup:
 
Now that you have flywheel numbers, it would be good to now get the car on a chassis dyno when its all back together and see just what the drivetrain loss is. Do you still have the u-jointed halfshafts or did you also install CV's?
 
What's the theory behind using crmoly push rods? keeping the valve train weight down? My GT6 revs quite easily to 7k without any valve bounce, using factory supplied push rods.
