Dyno with and without vboost?

[[email protected]]

Anybody ever do a dyno without vboost and with vboost? Just curious how much power it might add. My vboost control box is not working so right now the butterflies are completely closed. I took it out and rode it for about 25 miles like that and it ran pretty good but had a bit less power. I'm planning to power up the servo and open the butterflies and run vboost all the time but ran out of daylight last night.

Just curious if anyone know how much hp opening the butterflies may add?

It should be the same as with if you tune for it. Same main jets but I changed needles a 1/4 clip in one direction, MK177.5 PAJ2 and slight adjustment of mixture screws.

yea the top end shouldn't be any different, setting the idle screws/needles take a bit more work.

i think the small throttle opening roll on power is a lot more fun with vboost open at all rpms. plus the idle sounds cool.
