R33 Gts-t Turbo Lagg?

[TRYNCY]

hey guys just a question, when i reach about 5 and a half revs on which ever gear my car tends to lag, not goinng its full performance is it the turbo or is it that not enough fuel is going through therefore theres a problem with the fuel injectors??.

thanks

what boost? turn it down does it go fine?

Turbo lag means the period before turbo hit its set boost. So if you have a really big turbo you would experience lag before 5500RPMs. Can you detail this lag that you are experiencing?

the thing is ive got a apexi avc-r boost controller, and i dont know how to use it, im going to take it to a dyno tune this week, so hopefully they can help me.

R&R? spark breaking down?

A list of mods would help..

[defari]

clutch in - smash the gas - clutch out.. no lag

on a more serious note - need more info - what mods? standard ecu? stock turbo? coilpacks are eff'd? spark plugs are rooted.. the list goes on..

[ClutchBurndout-:(]

it wouldnt be the injectors failing, because it would go faster from being lean (not good)

Turbo opens/on/operates all the time, when you see boost all depends on the Amount of Throttle and the amount of Load on the motor (In gear, not free revving) this will change though and you can add the size of your fuels system, intake, turbo, exhaust blah blah..

turbo will boost from 2000-2500 rpm - hopefully hit full boost around 4000rpm - 4500rpm up to 6500rpm (roughly)

(assuming stock ecu / stock turbo etc etc)

so before 2k rpm the turbo is doing nothing? is that right? also if the car got an intercooler it sure got a turbo right?

please bear with me.. totally newbie! tnx

apologies to the OP (dont mean to hyjack the thread but i feel compelled to answer his question as we were all newbs at one stage)

before 2000rpm the turbo is still running although its not making positive boost pressure.

in regards to intercoolers - generally yes - although u do find some people (i have no idea why) putting intercoolers onto non turbo / non supercharged cars.

if you have any other questions, just PM me - saves cluttering this thread up as its a bit off topic.

thread starter sorry if i ask questions here..

cheers..

wrong. boost threshold is the minimum rpm required to reach target boost. lag is the amount of time it takes to reach full boost after planting the throttle above the boost threshold. getting technical but you should know this

[TRYNCY]

no worries, have a look at this topic guys maybbe my boost being high isnt the problem. something with the pipings?
