ok guess ive been wondering for a long time and have asked numerous people this question. WHY WILL A TURBO NOT CATCH BOOST WHEN IN NEUTRAL OR WHEN YOU HAVE THE CLUTCH PUSHED IT? the only answer anyone can seem to give me is that ohh because the motor isnt under a load... well my thing is no matter what if you have it in neutral and you rev the motor to 7k rpm you still have the same amount of exhaust flowing to the turbo which means the turboine will spin which means that the intake should push air through the motor but it doesnt why? i know its not because it isnt under load because you can jack a turbo car up off the ground and go through the gears it catchs boost?? what load is that under bairly any load at all so can someone please give me the real reason why the turbo wont catch boost anyone?

 

i believe that the load of spinnign the tires is enough to build boost.

I'm not entirely sure though, but thats the only thing I can think of.

 

but what im trying to say is what would the motor being under load have to do with anything because no matter what at 7-9k rpm the same amount of exhaust will be comeing out to spool up the turbo... and the waist gate isnt open when your reving in neutral so there really is no reason for it to not spool anyone else have anything to add because i mean seriously my head is hurting trying to figure this out without anyone to argue with lol

 

neone?

 

when you rev a motor at idle is it producing the same amount of power as it would be if you were say crusing at 4k in 3 gear? It takes horsepower to make horsepower..

 

i always wondered this ,just a thought though when ur engine is under load it will add more fuel which means more exhuast gas to spin the turbine, on antilag systems it adds loads of fuel to run rich to spool the turbo while sitting still , also they retard the timing. try holding in the brake when cruising and try accelerate , build boost with load . im sure theres a scientist that can explain it better .
