boost bleed off? boost carry over?

[fastcarfastbike]

if you hit the rev limiter, does your boost get bled off or something...and if you shift before the limiter, does some boost carry over to the next gear or is it like a turbo where the boost goes away and you wait for the spool...



anyways my question is this

if you throw it in 2nd, and hold at about 3 grand, and floor it...its like, so many seconds from like 40mph to 70mph....like 4 seconds or so


if you floor it through 1st,and then start timing once you hit 2... 2nd gear pulls a lot harder...that if you had just floored it in second like in my 1st sentance....


im gonna assume this thread made ZERO sense,,,

i see what u mean. do we have to re-build up boost after shifting gears, once you're back on the throttle it is like instaboost, no waiting, but shifting just loses it for a second. i might be wrong but i dont think there is a noticable difference in performance

When you shift hard the car isn't bleeding boost off [well it is to a degree, depending on weather and shit, but it is giving you the max boost the ecu will give you].

If you are coasting in a gear it bleeds off the boost to give you gas mileage as you are cruising, not accelerating.

ahh ok...so i was kinda right then....if you took a stopwatch and timed the time it takes to go all the way through 2nd gear from a good shift from 1st vs a roll in 2...it would be better with the shift because you built up the boost in 1st....
