Triumph TR6 - Roller Rockers

Greetings all,

I understand there are two companies out there (possibly more) supplying roller rockers of quality, being Richard Good, and Ted Schumacher of TSI. I have heard also though, there are others out there selling sets that appear to be very much the inferior, resulting in problems with the roller tips galling and showing excessive premature wear. Anyone have any experience with this item they wish to pass along?

Ken, sounds like you are souping up the straight 6.
What happened to the V8?

I have a set of Ted's roller rockers purchased some time back. Unless things have changed, his are loose rockers, you supply the shaft and pedestals. Reasonably nice pieces, fit of the #1 and #12 rocker are a bit fiddly into the stock pedestals.

I also know someone who went with Richard Good's roller rocker assembly. I can tell you that visually, it is a work of art. They did have to make one slight modification. This is on a race engine using ARP hardware. They did wind up have to do a bit of grinding on one of the nuts for the cylinder head stud to gain a wee bit of clearance. Using stock head studs and nuts, this modification would not have been necessary.

All in all, if you are going to go with Ted's and select the needle bearing option (which requires the use of the hardened rocker shaft), you still have to do all of the assembly and set up. If you use solid spacers shimed to valve location, it can be a long and tedious process. If you go with Richard's, you get a work of art that is ready to bolt on. It boils down to probably something along the lines of about $100 to $125 difference when all is said and done. What is your time worth and how do feel about unseen art?

Note that if you have one of the earlier style aluminum rocker covers (the ones with the big recess bosses where the mount studs fit), they will foul the roller rockers. You have three choices, run the stock rocker cover, buy one of the later style that are relatively flat without the recessed bosses, or modify the rocker cover to eliminate the offending bosses. The last option is not difficult, but does require some fore thought and fabrication.

I installed the 1.5:1 roller rockers (non-needle)from Ted Schumacher combined with a new hardened shaft and noticed a "seat-of-the-pants" gain in power. The rollers were approx $300 US. In order to get Ted's rockers to fit I had to spend approx. $15 CDN at the bolt supply house to purchase some hard washers. It was about 2 hours of my time. Note that the Goodparts roller configuration is big money in the $600 USD range. Also note that if you are going beyond the 1.5:1 ratio you will need to run camshaft bearings to ensure long life.

In my humble opinion, the TSI option is best for the average guy off-track.

As an aside, I ran into an oiling problem that destroyed the roller rockers. The problem was caused by some machining debris in the oiling holes of a couple rockers and I didn't check prior to installation. Ted made good on that and shipped me a new set at no charge. Just an excellent business to deal with. Mind you, I'v also done business with Richard Good and he is an excellent guy also. Goes to show that in our hobby there are some real integrity people out there - Herman Van DenAkker is another with his 5speed etc....

John, it sounds like an absoloute jem. Why are you selling it? Sounds like a sweet ride.

I'm trying to find a way to keep the car but I miss having my family along on those wonderful sunny summer mountain drives - I'm after a 4 seat ragtop in the order of a 330CIC. It would be a shame to part with the TR I really love that car.

Does TSI have a web site, I never saw that name before?


J. G. Catford

Yes indeedly doodly, Ted has a website. Check it out:
