bit OT, but since you brought this up:
i am aware of high oil temps at the track (we all have oil temp guages), but i am not aware of high coolant temps (we have no water temp guage that i am aware of).

note that i have the second oil cooler (inside passenger front fender) but still saw 135 celcius (275 farenheit) while doing hot track laps.

kindly elaborate re engine temp.

True, turbo cars wont benefit as much from ram air as the NA cars. The turbos will suck in much more air than the NA ever would. With that, we still see a benefit from the scoops as it directs air into the stock intake opening.

Not every company will make or sell these things because many of them want to sell you a cone filter with a shiny pipe.

At this time, we have no plans to release the scoops for the 335i yet. We already have a few volunteers that will have the scoops installed and dyno tested. Our dyno tests are done with 70mph winds. Winds lower or higher than 70mph will/may see different results. For example, we have M owners who have gone over 150mph then go into limp mode from too much airflow.

Those who are familiar with our company know about our "open house" testing. When we test products, people can come watch us. If it does nothing, its scrapped. You'll never see bogus products coming out of here. We released our 335 intercooler a couple of months ago and we guaranteed its 80%+ thermal efficiency rating. More tests on the scoops will be conducted before we make any official claims.
i already have your IC (bought thru supreme power).
i live at 9,000 feet and think these scoops could be v benificial for anyone at higher altitude. if u want to give it a shot, i can test them for u.

i already have baselines to compare to if i add your scoops.
u can PM me if interested.

well I just wanted to hear from the people that have them. I'm thinking of pairing this along with an airbox that I made so that it can push cold air in there more effectively

IMHO, on a mod like this, the best indicator of gain would be road testing:
1/4 mile times, 0 - 60 and 0 - 100 times.

just my 2 cents.

RPI will be having their Open House on Feb. 9, this Sat. Lots of M5/ M6 for dyno day, but there may be an opening for you to get your dyno done...get there before 8:30 am . We will bring our customers 335 (V2, cai) if he's not up the mountain snowboarding
Wouldn't hurt to call ahead to reserve dyno time, it's at a very fair price too!
