IIRC The GT series turbos weakness is the roller bearing if your using anti lag.

Heat is an issue on ANY turbo and this is why they use the Maram 247 shaft for anti lag applications.

I don't think the T4 on a RS500 would take anti lag any better than a T34 would tbh.

Ofcourse I could be totally wrong but I'm guessing no turbo came with a 247 shaft as standard so really anyone using anti lag on their turbo is playing with fire unless they have upgraded.




Whilst on this subject, a 247 shaft is LH thread yeh ? I have recently read about a guys evo on our forum and it has a Inconel RH thread shaft in his turbo, now I have a good idea why its RH thread but can someone give me a correct answer as I dont want to say what I think just yet
