Question for the BP folks out there... When does your boost kick in? Journal bearing? Ball bearing? Light weight/mid weight /billet steel flywheel?

ball bearing here boost kicks in about 4K then 5k its insane!

4k?

Ball Bearing - my boost threshold is 2.5k and lag is a few hundred rpms

2.5k and JB

I have the Journal bearing and in 1st gear; I breaks boost threshold at 3100 rpm. Every other gear breaks the threshold around 2800ish rpm if I get on it hard and sift fast.

You guys all running 1.15 A/R?

>2.5K running WOT after 2nd gear is literally zero lag time

Yupper.. its a hoot. Think about it. In 1st your usually at a stop. That means the turbo is hardly spinning as it is only get idle exhaust. You wot to 7k and she is spinning like a mad hatter. You put it into next gear (sold be like 6000 ish) and wot again. There was what? 1 sec between to reduced exhaust to spin her which means it's instantly makes boost.

Now let's say you are just putting along and drive normally. Your in 1st, change gear to 2nd. I change gears at 3200 rpm in just about every gear. This means the turbo is already spinning a good amount. Not enough to make boost buy not far from it. So if I happen to drop into 2nd (it would drop to about 2300 ish revs) and give her 1/3 throttle, I would make boost just about instantly. 500 revs or so and bam! Break boost threshold due to the fact that it's already spinning a good amount.

Good to know/see that the boost kicks in at around the same rpm. Give/take 500. Tq is turned down on both applications for safety/longevity reasons. Thx guys!
