9mm vs 11mm pumps

[Ruan]

Well, I don't know if it will make a massive difference... I mean, I've only melted one vane mechanism... But that wasn't from high IATs... In fairness, my car runs 20-22psi of boost - stock they were 14psi and it's a bigger turbo, spinning slower... Being a much more efficient turbo, the heat should be even less, at 14psi of boost, it should be LESS heat than the original, the exhaust side is less restrictive, so there should be less heat contained in the engine... The IATs are IMO not the problem, but it's more of a preventative kinda thing...

It's in the hope, and also I'm making my own inlet manifold based on the stock one, in an attempt to not have either a Xantia Lunchbox strapped to the back of my engine, or the stock one with one of those 'orrible adapters which are just horrible for any flow...

Turbo will probably stay the same, unless I find a super cheap 2056 or 2256... This one's good for 200-220hp...

Remember my car made 175hp ATF with only 21-22psi of boost...
