I came across these a while back due to Graham at my local tuning place (X-Spec) as he was working with the company by testing the plugs to see what they can do.
Well first off i thought, blah! these are just another cheap "great" perfromance upgrade that wont do a thing, probably kill my engine faster. But a few weeks later Graham told me about the testing and was extremly pleased with the results. So I booked my Vectra GSi in for a set of 6 and a session on the rolling road.
So test 1 was to see what the car was running and produced 172bhp at the wheels so was running about 10bhp more than standard with the mods i had.
So we fitted a set of Pulse Plugs and gave it another go. We hit some problems as at first we didn't realise one of the plugs was faulty but we ran it again anyway and actually made 3bhp and 4lb of torque just running on 5 pots lmao.
So out they came and another set fitted and test 3 commenced. All of a sudden I see the difference when the car was tested. The total BHP gain at the wheels was 5bhp and 12lb of torque, but when I started looking at the results of the "average power through the range" this is where I saw the difference the most. The average bhp went up by 12bhp through the range and 28lb or toque through the rev range. Also the inherent flat spot that Vauxhall V6's suffer at 3500rpms was almost totally gone and the peak torque came down by 580-600rpms
So I was well chuffed as I didn't beleive for second that these would work so well. The only down side is that they are £25 each but the money is well worth it. I'll try and get my video of my DVD camcorder so you can all see the results yourselves
But here some links about them :-
