As above, 550s are perfect.
Gearbox will be weak link - temper your launches/gear changes (unless you
already treat it with respect, of course.
).

419.5 on a warm day with 10% meth on 2l , for some reason the 2.5 just don't make the same power. When it went on my 2.5 it made 407/435 and that was a nice spec for the road anymore power and I think it's mental for the road.

400 bhp + is possible on V power if you run the correct cams.

All the above results highlight the hit or miss nature of the 20g.

You need to run reprofiled cams on classics along with good charge temps in order to break 400bhp on pump fuel.

True they are hit and miss but as long as its Harvey or AFP you have a chance. At least it wont fall apart like EBAY ones!

That's it mate - if you
expect 380 (on 550s), then you
should be okay.
Regard anything more as a bonus...

That's it. Only buy AF or harvey jobs - a
known quantity.

A 2.5 litre on a 20g goes really well and 380bhp should keep you happy for a few weeks.
Are you using a 3" turbo back exhaust system?
