I would hope so considering we have an extra liter, 2 more cylinders and another turbo to boot. We run 19psi stock as well. Man I don't even know why I brought this up, but just mentioning it makes me want to get another Evo and run E85 all over again. Nothing like lighting up all 4 tires in the street.

Its funny how people are comparing boost between cars. That's the most ridiculous thing I've heard in a long long time. Air is a fluid. Boost is nothing more than resistance to flow! That's it! It tells you ABSOLUTELY nothing about how two different engines outputs compare if they have the same amount of boost. Quit comparing boost values from Evos to our cars and saying that our engines run low boost.
Go boost a Toyota Corolla LS and see that the con. rods on those engines begin to twist at 6psi. Now all of a sudden N54 running 14.5psi is insane amount of boost. Long story short: boost values should not be used for comparing engines. Period! OP: nice video. I hope you sort out that misfire problem of yours soon!

What you missed though is mentioning CFM (volume of air coming out) and how psi with smaller turbos doesn't equal psi on bigger turbos...me running 13.5-14psi with RBs is about a 50-70whp difference from stock turbos with lower EGTs...there's a lot to be said... |

Using PSI as a unit of power is about as good as using compression ratio as an indication of hp. "My Honda civic R is better than your Corvette ZR1 because it has a compression ratio of 11.0:1 while your mullet mobile only has a cr of 9:1. See you on the track, loser!" I'm actually agreeing with Vasil 100%. What is this world coming to? |

105-200km/hr in 8 seconds is probably around a low 9 second 60-130mph run
On my 7.28 second 60-130mph run I entered 105-200km hr in the settings instead, and it came out to 6.03 seconds.

The 7.28 was during a 1/4 mile run with normal automatic shifting at redline. But to put things in perspective, your time in the video is about as quick as my times on 15psi and meth. My 9.0x runs required 17psi. You will find that dropping a full second or two will be harder than you think. But can't wait to see some RB turbo times in the 60-130 sticky to see the improvements!

plus the pull after 6000 rpm and after 200 kmh which is completely different than stock turbos.
