but you can till drive at say 4k with out boosting.asim said:Ah yes turbo lag, mines doesnt spool till about 3500rpm so if I want economical I just dont go over that rpm range.
Not stictly what turbo lag is.MuvverRussia said:Uhh, why?
With a handful of exceptions, turbochargers only normally tend to work once you hit a certain rpm (2500-3000rpmish for a petrol car), as they need to spin up. That's why you get turbo lag.

then again the engine since its mapped for boost will be sluggish.

I can't think of any time you'd want to have a switched turbocharger. If you want to drive economically, then just use less throttle.

i don't know why, but i really wanted you to have factored into the above post somewhere the words "flux capacitor".Will Gill said:disconnecting the actuator will disable the turbo, probably a complicated way to automate that with some funky stuff, but it would drive like a big lump of poo.
i drove a caddy a while back and i'm sure when cruising along the engine switches off 3 or 4 of the cylinders.Hate said:Its like (I know its possible cause i've driven a chevy impala) getting a V6 and wanting to turn off half the cylinders.

* if only it wasnt all over by 3800rpm!

for the more technically minded (simon, johnnycoupe etc) i have a question.
in cases like this, is it always the same cylinders that are switched off or is the order rotated around all of them?
the reason i ask is, if it's always the same pots that are deactivated then doesn't it put a lot of unbalanced and undue stress on the crank?

i actually laughed out loud at that, hehe.Will Gill said:(p.s. I tried to insert flux capicator here but thought I'd take you unawares at a later date )
