I recently purchased a 1977 Triumph Tr7 with a 1980 Buick Regal
Turbo V6 - T5 5 speed in it. I've had a problem with it since day one. In 1st gear, if I rev it up and dump the clutch, it boosts to 7 and cuts out like a governor is killing the engine - if I back the pedal off to say 1/2 way, it boost fine to 7 and maintains till I put
it to the floor again - then it cuts out again till I let off again.
The motor does not die - it just runs and does not continue to
accelerate. It also poofs a black smoke haze out while it's cutting
out. I put new platinum plugs in it, new wire, cap, rotor, most of
the vacuum hoses, took of wastegate actuator and cleaned it,
I also cleaned the PEVR, replaced air filter, rebuilt carb and used
new float. It runs and idles fine, but at full boost it continues to
poop out. It has a black box on the fender with wires running
all over the place, and it has a really old looking relay right beside
the box on the fender - The box says ESC.....
Can anyone help me or tell me where to start ?
I bought and 80 Regal dealer shop manual, but I would like someplace to start from.
From some of the postings I've looked at, some people say it
could be the plugs, could be wastegate accuator, could be coil....
What would one of you gurus out there do first ?
I would really appreciate any help .....
Thanks, Ryan
PS- could someone tell me what the horsepower of this engine is,
and if boosting at 7 is normal, or should it be going higher ?
I also run at 18 on the vacuum side at a 900 rpm idle.
I can also send pictures to you if you email me....
