Hi guys
one of my fellow 3.0 v6 vulcan probe owners finally took his turbo 3.0 probe (the first of its kind) to the dyno after few months of installing the turbo and got the following numbers:
Well my first time at the dyno and this is what the 3.0l turbo made.
252.5 @5000

here is what happened during this run according to him.
15psi with 91 octane with stock advance. I had major problems with running rich. The motech wideband o2 he had to measure a/f ratio only goes down to 10.3 to 1 where i was, way below that where the motor was studdering from the plugs being wet. I want an a/f of around 11.5-12.0 and this is where i was.
rpm a/f kpa
2350 11.5 123.3
2419 11.0 126.83
2545 10.3 134.66
2500-5000 rpm the car showed lower than 10.3 a/f ratio.
everything below this completely went off the graph. I start making boost around 2300 rpm so this car is extremely rich right off the start and chocking on the top end.
His screen name in probetalk.com is turboed jimmy and is the only guy that we know of to turbo a 3.0 vulcan v6 powered probe.
BTW he IS running on stock internals but as you can see hes been having a hard time tunning this setup
might be getting the video of this run on the net soon for everyone to enjoy
