I've looked into achieving high comp by means of virtually interfering the piston to the head, massively shaved alloy heads with flat faced valves to reduce chamber cc and the best I could do was about 12ish :1. Custom profiled pistons are a must on said engine deign.
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.
And after...
Wow... It's been a long road, thanks everyone for all the input
But... That isn't the true weight of the car, one of the load cells is a bit out (same amount as first weigh) so this still gives a great idea of the loss. I have another 'higher quality' set of scales which I'll put under the car tonight and post the real weight...
Thats fantastic have to be happy with that. Less weight and more power too? How is the tuning going?
I've just started a car this week first time using 11P (but running a manual trans)
Yeah more power, much more torque thanks to e85 conversion.
Learned a lot about tuning on this mission, especially with the new fuel. I think that with the dfco wired in and working as well as the closeness of the tune, hopefully will see similar fuel economy. (Very important in endurance racing)...
