Joe:
I think we are going to agree to disagree on that one. Fuel injection
offers no more ultimate power than a good carburetor. The advantages to
EFI are numerous, but ultimate power is not one of them.
As for the PI TR6 delivering more power than the carb'ed versions,
you need to be very careful. The PI cars had numerous advantages over the
carb'ed version:
1. Higher CR. PI cars were 9.5:1, carbs were 8.5:1 and later were
7.75:1.
2. Camshaft: 150HP PI cars used 280 degree cams, carbs used 240 degree
and later used 256 degree cams.
3. Rockers: PI cars used higher ratio rocker arms, so the valves
opened faster and farther.
4. Exhaust: The PI cars had dual exhausts from the beginning, carbs
did not get them until later when emissions controls were choking
the life out of the car.
5. PI cars did not have vacuum retard on the ignition, instead they
used an aggressive, mechanical only ignition advance curve.
6. The PI cars came stock with a cold air induction kit, carb cars
draw hot air from the engine compartment.
So the PI cars were getting their power from many improvements,
not the PI per se'. Admittedly, the Strombergs are a bit on the small side
to deliver 150HP, but a properly sized carb would have delivered every bit
as much power as PI on a PI car.

Vance,
About fuel injection sir, I disagree with you. Fuel injection ensures an
exact 14.7 to 1 fuel ratio, something that cannot be said about
carburetters. Plus the fact that fuel injection will deliver exact
performance every time. No fiddling with needles and above all, no need for
chokes. I can assure you that with a properly tuned PCM and the correct
injectors on a TR6 engine, you would increase power dramatically. Triumph
did it with the Injection cars back in the seventies and that was with the
non-computer controlled injection.
No flames here. Folks, I'm not picking a fight!!! I am not trying to insult
or upset anyone, but injection is the way to go. Carbs are a thing of the
past.
Joe
