Good answer! Cheers Robin

Would be good if someone could be bothered to add bits one at a time so the effect could be seen, quite a long project, and you'd need a friendly RR!

I need to get the porker on a RR to get it fine tued by someone who might know what they are doing. I'll see about getting the Lizzy done too.

Over time various people have done various back-to-back tests. The problem is that once you want to test four or five components, the combinations and permuations get quite scary. Also, sometimes other factors limit performance and so the true potential or damage of some "upgrades" will be masked.

Enjoy the R/R with the porker!

Cheers,
Robin

I always thought cams were a head off job, oh well.

Robin, that problem is persisting so if you want to have a nosey, let me know and I'll bring her round. Fingers crossed running the car at the moment isn't damaging the engine

Too the rocker cover off a xflow engine yesterday afternoon to prove it was not

Looksl ike the timing is going to be the hardest part should you not lock the cam wheel thingys at the end.

depends on the cam spec requiring uprated valve springs ?

You can actually change the springs with the head on if you like puzzle solving ...

Greg - we'll try the bodge to dampen the IACV response and if that doesn't fix it, we'll whack the standard cams back in OR you can borrow my emerald and get it tuned on a rolling road, just so we can see what power it makes.

Cheers,
Robin

yep theres a couple off tricks the trade use

Is that the one with compressed air in the cylinder adn a special tool to compress the springs? Always struck me as dodgey as if the valve does open at all surely it will drop in? Or is that not the case?

I guess that you could work on the cylinders at TDC then rotate the crank 180 degrees?
