Anyone on hear with engine experience with a Westfield using a Hayabusa power plant. One of my collegues had his in for emissions testing and failed, as he could not get the CO2 levels down. I'm not sure on his configuration, but I'll pass on the contact details if anyone is willing to help.

Surely the fact the engine is in a car has no bearing on it's emissions testing?
I take it the car in question is a self-build and failed on its first MOT to prove road-worthiness?
What's he changed on the induction/exhaust?

Squiz - You are right on both points, road worthiness and a self-build.
As far as I know he has followed everything according to the Westfield book, however, he has told me that it is an imported Hiyabusa...so maybe the fueling is a problem. What causes high CO2 levels, is it too much air or fuel, or both??
Are you familiar with the Westerfields and Haya's??

I'm familiar with Westfields to a certain extent. I used to work around the corner from the factory, and was helping a friend build one a while back, but that was FORD X-flow powered.
I'm not too hot on bikes. Got friends who are that I can ask, so unless someone beats me to it I'll find out if Jap bikes are "dirtier" (
) or not. Can't for the life of me remember if bikes have catalysts either!!
Westfields themselves should be quite helpful on such a matter.

I'll second what is said above - I have a lowly blade engined westfield ('only' 330 bhp/tonne rather than 450 for the busa ) and they do just need a visible smoke test for MOT. Suggest getting your chum to go to a better informed MOT centre!!
If a Busa engine, and thus post'95 he will need a cat on the car anyway, but Cat convert gases into CO2, so that may be the problem?
Best source of info will be from the bike-engined-cars forum on Yahoogroups
Scream if you want to go faster

I reckon it is the SVA test which is causing the problem here. The Westfield does need a cat to pass the SVA, and even with a cat it can still fail due to high emissions. Don't know any way round it except to get on the blower to Westfield. They sell the kits with the exhaust which is supposed to pass the SVA if built according to their build manual. Perhaps another cat is required??

GW2000, never mentioned the SVA.
I know it sound like a pain in the butt, but once the car is through an SVA you can modify it without restriction.
Aparently you don't need an SVA if you use everything from a donor car. (info from a tester)
Its a good idea but registering a classic replica is a pain.

The exhaust system for the XTR² should (fingers crossed) get us thru SVA - westfield have built the system with 2 baffle boxes and mighty big CAT in the main silencer.
Check um out:
Now - just to find the donor engine and finish the car

from what I have found regarding the SVA:
pre 95 engines you can run carbs and have <3.5%co, you can use carbs and get through easy.
post 95 engines require injection and must meet a lower rating. I would think if the Hya. engine is injected(?) and can be tuned to run under 0.30% at 2500-3000 rpm it should pass. You might not need a cat if the engine runs that clean.
i found most info on http://www.ilsuk.clara.net/SVA.htm but the Gov. site was useless. There's a surprise!

Wow - Thanks for the replies. You guys are right, it is all to do with the SVA test.
Apparently what I can get out of my friend is that it failed on tick-over CO2 emissions, the running levels were okay. According to Westfield all you need to do is play around with a 'screw' on the engine to sort this out...this was done, however, the car still failed. Unfortunately Westfield are not being very helpful and saying it is something wrong with his setup...possible I guess??
He has all the right parts for the Hayabusa power plant, but it is still not running right. My friend told me yesterday that he now has some engine management software that can play about with the timing.....very scary as I don't think I'd be playing about with that...is that my ar$e or my elbow
I'll pass on your information and see what changes he has done over the night. Oh, nice looking exhaust, I'll pass on the pics.
