Yea, bud.. that's what I was referring too. Thanks for posting, I couldn't find it.
Do you think the turbos are capable of flowing more air than the 475-510whp? Meaning, if we installed modified CP3 R90 pump and modified Bosch injectors, is there enough airflow to make any more power and to make this investment worth it? If so, how close to the limit are we... would we be looking at 1whp or 50whp increase with additional fueling? Is upgrading the fuel system the next step to making more power or will we be limited by the turbos airflow once again?!
I assume we're at the top end of these turbos, I can't imagine getting 67-68lb/min out of these hybrids.

This airflow question, since we are saturating the MAF and it can't read the actual flow, was the whole reason why I developed this method to be able to get a measurement on airflow: http://www.e90post.com/forums/showthread.php?t=1210979
You can also get an idea of airflow from calcuations from matchbot. But this requires you to have good logs of critical data to fill into the calculator. And you have to make some assumptions about certain parameters (like VE for example) ... but if you can measure airflow you can check your assumptions.
An example of matchbot from logged parameters on the Pro Turbo config in my specific car was posted here and was coming in at ~64-65 lb/min at peak rpms: http://www.e90post.com/forums/showpo...&postcount=466
The measurement technique outlined in the first thread I linked above, was also showing mid 60's lb/min airflow. |
