[Mk2] [Turbo] Possible loss of performance, Mk2 rev2 Turbo

[TheCombover]

Mainly been commuting to work and havnt really taken her for a blast in a while, but today I gave her the beans on the way back from work but when boost kicked in it didn't feel as fast?!

What could cause this?

Thanks,
Patrick

Hi Patrick, a brief run down of your cars engine and mods would help with a diagnosis .. it could be a simple boost leak (are you boosting the same) to running in bad gas mode if its a rev1/2 ...

My car is running a hybrid ct26 turbo, gutted cat, hks silent Highpower exhaust with cut out silencer, aftermarket intercooler, greddy OLED ebc, I always run it on shell v power.

Last time I checked both my gauge and ebc read 15.5 psi. I will double check that tonight.

I'll check this weekend for any boost leaks

Im finding my car is a bit sluggish at the mo but blamed it on the hot weather. Im running a greddy copy intercooler without the shroud so thought that could be it.

[TheCombover]

Never thought of that, it has been silly hot recently which is not ideal for us turbo people.

But is there anything i should maybe check? Just check hoses for leaks?

[markstevieandmads]

Id be turning that boost down to a bar (14.7 psi) unless u got better injectors and a steel head gasket.

[TheCombover]

Ahh maybe that was my mistake I have been running it between 15 and 16 psi ] will turn it down see she's happier

Turned the boost down to 14psi and seems a lot happier!

Good to hear buddy ... it could be hot ambient temps plus turbo being stressed at 16psi (producing a hot charge) coursing low performance .. anyhoo glad its sorted
