If K04+ is capable of 360+whp on 93 octane, K04R should at least be able to accomplish that if not more.

Cudajoe- I have the + and have communicated with a couple of the guys who have the r. It seems that even though the r has a bigger wheel, there is only so much flow you can get from the housing. I haven't seen anyone yet getting more flow out of the r, at least the 3 guys who I know that have logged it. If it's equipped with the high boost actuator it can hold more boost above 6,000 which is where mine starts to lose it, but it hasn't gone any higher than 38 yet on flow that I know of. Given its half the price of a + it's still a great deal, but I'm not sold that it's capable of 400hp on e or e47. I wish it was because I would go to it.

Yeah and if u look at that chart the + is like 8mm and 7mm smaller on the wheels the r is only about 4mm and 1 mm smallr. Then a zfr but the size is still way different lol pretty much the + was good about 4 years ago the R is where it's at now for a low cost power bump

For the money you can't beat the r. My+ is better than stock at all rpms judging by butt dyno, and I have been happy with it. The r wasn't around when I got my + 2 years ago. They both are stock machined housings and it appears that they flow comparably due to you just being able to more only so much air with the housing, no matter how big a wheel you stuff in there. Kmo4- 2 guys I have contacted are about done tuning theirs and they are sitting around 37.3-37.4 maf. I'm not saying you can't get more, just saying what they have told me. 37.3-4 is what I normally see in 3rd gear on my + which is about 3 more than stock. Housing kills much more than that. I'm not boost spiking or anything either and I'm ramping not going with full on hit.
