CT458 vs CT358 what would you choose?

[A80Avant]

who voted and dug this one up again! i went to GT3076 eventually!

[david]

good choice mateperfect for 4k rpm spool
hope to go for thesame turbo in the near future

[A80Avant]

oh and by the way. Im very satisfied with this turbo

[Thuppu]

...surging down low brings spool later...

How can I tell if the turbo surges at low rpm's? Does it sound strange?

How to get rid of it? Custom remap and limit the boost request on the lower rpm's..?

Which turbo do you have ?

I bought a CT5658 with AR.84 hot side. Haven't mount it on yet, but I'm just a litle bit concerned about possible surge...

With the .84 hot side that should not surge, maybe a little lag with that though

I was running a CT 61 62 on a .63 hotside that surged ( the turbo should of been a ct 458 3b but when I measured the turbine it was found it to be a 61mm) Now replaced

I have a ct 458 3b with billet wheel ar .63, I will start remapping next week again !

will report back
