Cooler as been said is only a limiting factor if it can not cool the charged air and therefore loses power. There is no way to say an exact figure as every engine performs differently based on a variety of factors, health of engines, temperature at time of run etc. I.E another car with the same setup as you may produce more power or vice versa. But based on your spec be around 330HP max at a guess.

Another thing is never believe what some people say, some people "Claim" stupid figures which would otherwise be totally impossible for the spec, even with RR graphs you need to be careful as some forge these.
