Seem's poor to me...
I have a race turn out silencer, standard cat and manifold, and stock air-take with a panel K&N and make 133BHP.. Oh yes I have now rapped the top air intake tube with Cool-It Thermo Shield Tape and moved the air intake duct to the grill with a Revotec Rectangular Intake Duct With Stepped Outlet zip tied to the grill. Gives a ram cold air induction, you do notice the difference with weather conditions as you speed up the engine pulls better, this cannot be replicated on the dyno I wish I could to see the difference in power. I have done some old fashioned plug chopping and all looks good so I'm not worried about fuel/air ratios.
When I spoke to AT Power direct they were talking 160+ by raising the rev limit and 190 with a cam, I would also have to fit headers and a free flow cat.
At the moment I am working on a new intake manifold and filter system and Ram air system to see if I can squeeze some more bhp out on the stock throttle body , I will book some dyno time to check how I get on. Then the headers and cat will come and another dyno run!!
