Bad turbo bark

[blackcloudCTD95]

I'm in the process of buying twins so last night I pulled the 64.5 off to put my old 62mm back on

I forgot how much fun that 62 was lol it defiantly doesn't have the power that the 64 had . with out changing fuel I'm cooler and cleaner than the 64

When I go to converter lock up it barks and surges horribly until you let out. The 64 also did it but I knew how to drive arround it. Or I would have to prolong the shift and get the rpm up above 2200 then it wouldn't do it ( low rpm with high maf volume)

Since its done it with 2 different chargers could it be a converter issue. And will it do it with twins? Someone told me it may cure it. Im doing a 62/ 72 maybe a sxe 472

It'll go away with compounds.

Does having a 2nd turbo help or is it the larger housing on the primary?

What are all the spec's on your 62?

Having the 2nd turbo feeding air helps.

Each turbo is working less and kills the bark. The bark basically disappears with twins until you are starting to push that set harder than they can handle.

I doubt I'll really push these twins I don't have the fuel. I'm doing it for spool and driveability.

It barked with a 62/70/12 a 63/68/14 and a 64.5/73/14 . the 64 didn't bark as bad as the others but I really had to scream the rpm's.

Should I get a looser housing on the s400 like a 1.10-1.32 I was looking at a 72/83/1.25 possibly a 75
