RS2 Intercooler Power Limit?

[Rusty]

What are peoples' thoughts on this? Is the Wagner Evo much better? Current aim is about 425-450.

That is difficult to tell I think. With a efficient system, especially a turbo that runs good in its specifications and does not produce just hot air because it runs at limit, there will be more power possible. With a turbo running above specifications, the air is hotter, and the IC has to work better, so maybe with one turbo the ICs limit is 400hp, with another turbo it possibly can do more.

AFAIK it´s limit is between 400 and 450hp, so for 450hp setup I would choose the Wagner upgrade to be sure to not loose power in summer. Wagner one should be good for bit more, maybe ~500hp.


I just don´t know if there is a "piping limit", that is not based on cooling efficiency, but just on flow restrictions.

Good points.

I would be looking to have the IATs tuned to sensible levels and not go too boost heavy as on track it'll just heat soak itself to death.

As I'm on a generic map RS2 turbo I may go for a slightly larger turbo as I'm used to a touch of lag

An IC spray would be a good plan I think, just to keep things in check.

In Greece there were people running close to 500hp with an rs2 intercooler. It's very well made, and remember greece has a mean out ambient temp of 25C. So I'd guess 450 should be achievable in th UK
