hopefully they will be able to put less tapering after 5500 rpm to redline.

I now really wonder what this same map, even with low boost on top, makes on my car with RBs |

Dzenno sent me a log of his stage 2 running upgraded RB turbos. I plotted both mine and his logs. Assuming he weight 200lbs and has stock tire diameter on there, here are the results.

Boost doesnt come on later, he just started at a much higher rpm. Also boost with the rbs is nto quicker. It is simply easier to make initial boost at higher rpm. If both logs were started around the same rpm you would see identical boost traces.

Guess I didn't look at those hard enough. Thanks for clearing that up, I apparently need to look better before I speak. Hope to see a better comparison later.

My car weight 3380, I weight 250 and probabaly had at least 100lbs on crap in the car so I might have low balled my car weight which would give a lower number. In the next couple of days I plan on getting real datalogs to start using this a little better. |

Also this map that I run targets 11.5 AFR at top end as I was trying some things...so with 12 AFR that Clap is running there's maybe another 10-15 there, not sure...I'll try to get the same map clap is running so we get a more direct compare but I'd expect it to be pretty close...
Hopefully stg3 raises boost to take advantage of the RBs up top... |

Your load target and actual arnt even close. You low pressure fp is acting a lil wierd, you af ratios from banks act up a little and your throttle isnt really staying open all the way. |

It's not your stg2 map, mine is an experimental map quite a bit different from yours..they're working out top end boost so instead of holding boost past 5300rpm throttle plate is intervening and closing 50%...that's why actual load starts to drop rapidly starting at 5300rpm What I sent you is just the last thing I tested which wasn't anywhere close to beta or anything official |
