Mind you - its gonna be a stretch to get the cosworth to match that configuration with general tuning! ROFL

Okey dokey - shall be get cracked back into it - I know that some of our tech chaps will be Ringbound, so lets take advantage of them whilst they are still here!

Can we focus in a little on the cam timing? I want to see if we can shed a little light on this area of tuning.

Lets create another hypothetical. We have agreed now the following;

1. The bottom end is now configured for mildly low compression (i dunno say 7.2:1 - Does that sound about right?) All else is std - stroke, piston size, cc etc.

2. The clyinder head has been mildly ported - lets say equivalent to a Norris Stage 1?

3. The Turbocharger at the moment is to be say a T38 (I guess with a 0.63 zorst housing IIRC). I know that the popular choice would be the T4, but bear with me

4. The fuelling and mapping is a given, and will be correct for whatever setup we finally work with.

Now you will note that we havent referred to the cams as such. Having built my virtual engine, I now have a Boost threshold of shall we say 4000rpm or there abouts, and it is proving to be very unresponsive off boost. The car owner (Mr Blobby) has asked that Jacobs independent car tuners (patent pending) set up his car to if possible reduce the boost threshold, and improve the off boost running.

So where do we start?
