Rolling road update

Rossi Wrote:Cams around the 270-280 area with 8-9mm lift are what i used to run and keep the power low down. Combined wth some headwork which is easy to see where you can improve even with a dremel. i.e matching inlet manifold ports to head ports and gaskets.
Should set you back no more than £500, i sold a pair of HKS cams for £200.

Can you tell me the likely power output of this + higher compression as above ?

Depending on the condition of your base engine probably around the 150hp mark combined with a good exhaust system and induction kit.

The guy that did the rolling road thought the engine was making about 136hp at the flywheel and suggested it was not bad for a standard engine.
He only did a power run, no adjustments were made and I know his rollers are pretty accurate.
The thing I'm weighing up of course is the difference between a mildly tuned 16v and a standard 20v
Some people suggest the 20v makes a consistent 136hp at the wheels http://66.249.93.104/search?q=cache:WHCV...ring&hl=en (paragraph headed 4age models)
While others say 145-150 at the flywheel

Can anyone shed any light on this, has anyone ever put a standard 20v on a dyno ?
