noo 12.5 not high, nope im on 11.1 09 tsx's and want to run cartel stg4's but thinking comp too low.. 12.5 seems ideal on pump fuel and can run these cams for a dd :up:how high is high? 12.5:1 isn't THAT high if you think about it... they're on 91 pump! you've ran cartel stage 4 on 11.1 comp?
in our last testing in this new thread,Quick question regarding your fuel set up, what fuel pressure are you running with 410cc injector? what duty cycle were they at? are they pretty much maxed out?
I have some questions regarding my k24z3 engine... can i reach what you have done with my engine and cost wise how much that will cost... ?Daily Driven FG2

Yeah, lot's of passion for details like the insulation and friction coated pistons.This was a nice build, lots of time and $ to make it come out right 👍
merry Christmas to you as well , just getting finished up with the family visits for the day 👍Yeah, lot's of passion for details like the insulation and friction coated pistons.
Maybe the huge cams would have need a better fitting IM, peaking at 7500 rpm with DC 4.5 cams is way to early. Smaller cams like the DC 3.5 would be a better fit to the used IM, so my assumption. Would be nice to see more of such built long blocks.
Merry Christmas guys 😊
