Btw.. also as jarrod said they recommend these for larger turbos that breathe more up top.. They will sacrifice a little down low but for a drag application like cwills we needed every HP we could get int he upper Rpm's and these worked great!!

I would be replacing revolvers so I doubt idle will bother me. I'm looking to move some peak power a little higher in the rev range. It's for a track car, and although it's not a drag car it still lives up higher. Also I have a 9.5:1 2.0L I would like to eventually run them in. That would also be on a smaller turbo as well.. My tuner is awesome, and if it has been done or can be done Im sure he is perfectly capable I'm just worried that it might hurt response.

Well i think they would work well if your staying up in the RPMs however i dont have any personal road racing experience to say 100%..

Stock ecu, on a stevo8 spec ported IX turbo and here shortly a CBRD full version. Im already running RC1000's, SuperTech singles w/Ti retainers, Straight exhaust. The car will only be run on E85 or whatever the highest octane thats allowed in class.

I do however do not recommend pairing the BF cams with a smaller turbo like the Green or the BBK from Chad. I would recommend a more "mild" cam for your application. The smaller turbo's like I mentioned just dont move enough air for these big cams.
I would recommend maybe something maybe like a HKS 280.
Let me know if you need anything.

I've tuned quite a few different cams on the stock ecu and I can tell you the average self tuner isn't going to get the BF272 to idle well...it took a few extra tricks to make it happen. Also I'm sure having a super light weight tilton clutch makes the stalling issue more common but I rarely ever stall after working hard on the tune. Sometimes it takes the stock ecu a few seconds to catch up to what the car is doing and compensate. It's definitely not like stock but acceptable to me because I want the most power possible while retaining the stock ECU.

Bryan@GST does all my tunes and he had no issues with getting the revolvers not to stall with a prolite flywheel. I dont think idle would be an issue. Im only concerned with power output with these cams.

I can tell you I'm extremely pleased with these cams. I swapped a few parts and the combination is amazing.
before: stock head, HKS 280, stock short block
after: buschur head, BF272, buschur 2.0
this was on straight 93 octane with the HTA35R .63 (I'm on the HTA86 now, see second graph, unfinished tune, there's more in it)
