The Toffinator Posted July 25, 2013 Share Posted July 25, 2013 From alamo? They are custom specced pistons etc. I went for 9.1 just trying to work out how i can lower it just a tad to make it more reliableHigher comp is better if you can keep det at bay which should be fine on 99 ron fuel Quote Link to post Share on other sites
AdamB Posted July 25, 2013 Share Posted July 25, 2013 (edited) What ecu, fuel and boost do you plan on running? Ulitmately these will affect what your static CR can be. Is it 5E or 4E? The higher the better, greater fuel economy, more power, more torque, linear powerband etc, however as said you'll increase the chances of knock and you'll also need a very good ignition system to provide a strong spark under high pressures.

EPnick22 Posted July 25, 2013 Author Share Posted July 25, 2013 running stock ecu and turbo, on 0.8 - 1 bar on 4e lump, i have a 255 fuel pump, fpr etc I was going to stick it straight on the dyno once its rebuilt to give it a proper fuel tune, sound appropriate? whats your opinions on the spec that im running @AdamB Quote Link to post Share on other sites
AdamB Posted July 25, 2013 Share Posted July 25, 2013 My opinion would be it seem's like a bit of a waste of money to spend running a standard turbo and ecu really. You can run that boost pressure all day on a standard engine. Unless your looking to run some power later on? Quote Link to post Share on other sites
EPnick22 Posted July 25, 2013 Author Share Posted July 25, 2013 whats a waste of money? in 6months or so i do plan on running bigger power, only reason im going forged is cause i have no choice as 3 of my pistons went remember Quote Link to post Share on other sites
AdamB Posted July 25, 2013 Share Posted July 25, 2013 Ah yeah fair enough.Well how much power do you want to run in the future? I'd be looking to run a CR of around 8.5:1 for most setups. Quote Link to post Share on other sites
