My IATs were high at vmax. So much so power would have been pulled. I can not remember how high exactly. Hence why I have definitely decided to fit the meth kit, even if I run mostly water. I went with the big Wagner coolers. I think DO88's might have been the better choice. I went with Wagner as they included all the ducting etc. I am also fitting the Joe Toth scoops to help force air in to the coolers. Downside of those is the increased drag obviously.
