Turbo Spiking

[Phil Megroin]

Hi everyone,

I recently purchased an r32 gtst with an EBC. I have yet to figure out how to use it properly, however the other day i was having a fiddle with it to see if i could work out how to use it. Its a HKS EVC.. if anyone has this model can you please let me know how to set it? Thanks.

Anyways, i set it to 1 bar boost - and i revved it up and on my boost guage i saw it go above and over 1bar... and when it went over, something started beeping at me. I have been told this occurs when the turbo spikes.. or something..

What exactly is happening when the turbo is spiking? And could this be whats happening? It doesnt seem to happen normally when i drive around on .8bar boost.

yeah mate.. with that ebc u can set the boost at 4 different levels.. it starts beeping after it goes over the max psi or bar set.. in ur case, if its beeping when it goes above one bar then u've set it too high... i have mine set at 9,11,12,14 psi.. and when i flick it over to 14psi, it lights up red to jus to warn me that that is the max u can run.. u change the max boost levels too..

i wouldnt reccommend boost over 12psi mate...

Ohh ok..

but why does it go over even when its set to 1 bar?

i never have it on 1 bar, i jsut set it on that to test out the EBC.

I'm usually on .8bar with pod, exhaust.

Only time i'd go over this would be on cold nights where the air is already cooled for me - is this safe?

If you still have the standard turbo you run the risk of loosing your exhaust wheel as its ceramic... Saying that on my rb20 14 with the stock turbo (turbo back exhaust, fmic and pod filter so less restriction) for a while without troubles, and 17psi on a S2 RB25 turbo... its probably not worth the risk tho.
