Good to see Gail has done exactly what I asked. Devide by 1.5 to get actual figures. Also I would suggest to all builders that intend to use the ultima in the winter to protect the alley in one form or other. The lovely polished pannels below the radiator look dull after several thousands of miles and no salt.

Stig. That's a pretty impressive dyno readout but what really took my eye was the oil temperature, which never exceeded 78F during the whole of the test. In fact, once the revs got up to 6900, it actually fell. I think that you may need to wrap an insulating blanket around your engine in order to get the oil temp up a bit. I have an old electric blanket which I could let you have at a good price.
Hmmm, seems like i got my calculations right then....they have put the spec of CR, camshaft and timing on the top of the page...thank you .....plugs were going to be a problem selecting, but not now
Nice engine Stig, i hope you have a very long relationship with her and treat her with the respect she deserves.....(thrash the tits off it)

Stig,
I am interested in jet size. With the discussions on the board, I am considering changing the jets on my carb from 72pri 80secs to avoid any danger of a lean running condition.
I am curious to know what is used on your engine as a guide. Also what other people are running.
Are we using standard jet sizes or have people upped them to err on the side of caution?
The dyno sheet looks as if it has been doctored (white blocks on the scan) to remove the details on jetting, plugs & cams. Do you have the jet info or was it not supplied?

I think you will find that while an engine is on the dyno the oil temp will be low because it uses a Dry sump tank the size of a small house. On the car it will be allot higher.
Could even nock off what maybe 300bhp when fitted to the car.......

Except that the optimum oil temp for power is over 110 (according to literature) so maybe thats 300bhp to add!!!!!
