I don't pretent to know that much about tuning, I'm learning things as I go along, as I suspect are you despite your motorsport course.
I don't pretent either i am learning too that is why i choose a motorsport course. I'm still only a first year
Well in all honestly I planned to run 8.8-9:1 CR as Flea/Barbz etc runs 8.8:1 and JohnS runs slightly higher than 9:1 (he won’t say exactly what that is) so I am not the only one who has increased the static CR and I still feel there is nothing wrong with running 9:1.
The only possible mistake I have is that I skimmed my head and block too much and ended up with 9.4:1 (long story). I had the option to use a decomp plate to bring it back down to 8.8:1 whilst the engine was apart but I thought lets experiment, however it’s not the end of the world as changing the turbo to a bigger compressor could benefit to this factor. I am studying motorsports and it is all about testing your ideas and tweaking the results and I feel I have been very open in what I have been doing unlike some people who keep data away from the forum.
After another set of results if I wanna change the CR then off pops the head and on goes a decom plate. It’s no big deal for me as I am able to do this at no real extra cost (just my time and parts). I choose to experiment with my own ideas rather than follow the flock as if I don’t then I haven’t really learnt anything. My car is my toy, project and experiment and I have learnt so much from it.
So can we please now drop this and have some ideas on a turbo choice thank you
Also I’m am still compiling a graph to compare all the turbos but using this excel 2007 is a bit of a pain
