Power graph

[seabass859]

Hi guys, went with the local guys for a rolling road day today, here's the results:-

is this what you would expect for a standard apart from k&n 12year old car which has covered 120000 miles??

all the other guys had a fair bit more power and a much smoother graph although were lower mileage and had mods.

I would say not far off with no mods

I'd expect another 10 to be honest but it depends on a few things. Could the timing be out, is it overdue a service or is it just a tired engine with those miles?

so after these results I had a timing issue and a lambda issue which I had sorted thanks to Mick at diamond motors!

I'd also added a cat back Magnex system.

so another day at the rollers to confirm what she's running.

I had said before we went that I wanted 172bhp and with 171.6bhp I really cant complain.

Next on the list is to look at the air feed and try and sort out the fuel mix...

From what I gather I need to sack off the Pipercross induction kit and get either a Espace V6 airbox / standard airbox with a Pipercross panel filter to reduce intake temp thus ensuring better AFR and possibly a little more power/torque.

Yup. 100% standard airbox with a pipercross panel filter mate.
