Question: I have a Westfield SeiW with a 2L 16v Vauxhall XE in standard tune with MBE ECU & webber 45s. It was suggested by the WSCC sprint guys to come to you for a cam upgrade kit - taking my standard 175ish XE up to over 200bhp. I want a mild tweek for a bit more push on track/airfield days. Can you offer a mild cam & advice etc for mapping of the MBE ECU & jetting of my Webber 45s to suit?

Answer: I would suggest the cams, springs, caps and platforms from the CK200 kit. As a minimum we would also suggest you had the pistons pocketed. This should push you in the region of 200 bhp. Since the cams are hydraulic there is no shimming involved. This spec is used by quite a lot of our customers who run in the Westfield Sports cars series, both on carbs and fuel injection. They are a nice improvement and give an all round gain in power. You could go for a larger cam profile that involve solid followers and increase the cost, but you would then need to trade off some of the bottom end power. If you are interested in going further than the kit I have suggested, just let us know.
I would recommend the addition of vernier pullies. You could also add omega pistons, which would boost the compression and in many cases would see the engine performance rise over 210bhp.
