Dyno run with and without filters

[petrolhead]

On a spur of the moment decision I went down to Vulcan/HT for a power run today. Last year I got 146bhp but this year the old girl seems to have lost a couple of bhp and some torque, she's now pumping out 144bhp.

 

Then I took the K&N's off and got 148bhp (rounding up) but lost a noticeable amount of torque. The graph below makes an interesting comparison, hopefully you can see it.

 

The blue line is from when I was using the Ashley manifold instead of my own. The tappets and carbs were checked before the dyno run. Maybe she's getting a little coked up after 10,000miles? She still goes like a rocket and thats what counts.

 

Finally I stopped off at the M25 services to take a Arty snap:
