Looking for an upgrade to my HKS 272's, any suggestions have a big turbo and am running mostly 91 and c16 on race day. thanks guys

 

other cam suggestions would help too guys, c'mon no input???

 

What do you want to know? David already said if you have Jun272's or Revolvers keep them the BF272's will put out similiar power. It's a high lift/ramp cam. You need a upgraded valvetrain to run them.

 

I am looking to see if anyone is running these cams on 91 or in other place besides ohio and how streetable they are.

 

The BF 272's are in my car now...very streetable, almost perfect idle, I do have an AEM though.

Power gains I can't report...I put them in when I stroked my motor and still breakin the motor...I will eventually test them against a set og GSC S2 I have.

They are very driveable...no problems.

 

Buschur's cams are a HUGE difference from your HKS 272's.

Dave said unless your running a larger turbo, ie: 35r or larger, these cams are not for you.

 

he said he has a big turbo so as long as its a 30r series or bigger he should see good gains.

 

I have the cams i would like to know if anyone had info on the lift of each cam

 

I'd like some info also. I'm looking to get rid of my HKS 280's and try rhe BF 272's. Should work well with my setup...

 

Buschur just built my new motor they were showing me the new pistons they have to use because any other piston would hit the valves ,due to the lift of his new cam's.
I also have the bigger valves in my head, but I would ask Nick or Jarrod with a call because you'll damage your motor if your not running the special cut piston.Also David had showed me the new springs and retainers they use for them also.
I was running the revolvers before and BF272's idle much better.Good luck with them and please check before installing.

 

well i have a AEM and a GT37r with supporting mods, but it looks like i will have to call buschur, I don't really want to have to get new pistons just for cams.

 

This doesn't sound right, Buschur never told me about pistons to cam clearance being an issue, I would double check this, had them in for like 2 weeks with my std. wiseco pistions 9:1 no problems...reving the motor to 8500rpm.

I haven't been able to give power results as my main bearings where damaged when I installed the BF272's but I did rev the sh*t out of them for the 2 weeks...till I pulled the motor to rebuild it. The pistons where in perfect condition, when I pulled the motor.

I'm now breakin in my new 2.3 motor....will post result after my tune.
