I wanted to share my experience that I had this past weekend with Robi and his new Buschur tuned cyln head

ALL his other mods were identical to the last time I was out there and we started with the same base flash as we used before

AMAZINGLY - even though i thought we were maxing out the stock turbo last time - now there was significant new gains ALL the way across the power band especially in the low end spool up

Robi's car needed at least 13 - 15% more fuel across the power band whcih tells me he was moving 13 - 15% more air flow as a result of the Buschur modified cyln head

For those who don't know Robi - he is the most hard core evo customer I have and a real amazing driver and car tuner

What amazed me the most was that he literally, actualy was sitting in his passenger seat - SLEEPING - as I was blasting up and down highway 101 at 3:00 a.m. at speeds that were toyally insane

If you subscribe to the theory that real fast cars are made by the area of the power band under the curve then Robi's Stage 4 Buschur evo with head upgrade is prob the fastest evo i have ever driven including my own. It is making HUGE trq right at 3400 rpms and pulls hard and steady all the way to redline

For the $ $ invested - his set up is hard to beat and from what i hear he eats Z-06 vettes like they were standing still on long straightaways

Robi's car is entered in the so called OTC challenge and i predict you will be seeing great things from him

PS - Robi's co-driver Matt is also a real hard core Evo guy and really helped me out this past weekend with all sorts of assistance over the long tuning weekend

 

Al,

I just ordered the stage 3 + Flash from BR and have been considering their head also. Your post has confimed what I thought the motor would do with a better flowing head. Do you and Dave have a BR Flash for the Stage 3, 272's and the head? I don't have the cams yet and wondered what your thoughts were there. It is going on a new RS that is a weekend racer/streetsleeper. I got the Exedy twin plate clutch so I should be on with the drivetrain for a while. Thanks, Bret.

 

Stay with the 264's the 272's kill your lowthrough midrange torque #'s! (and if your roadracing thats what keeps you ahead NOT the extra 5 hp over 7 grand that the 272's give you).

 

is the new head worth the $1600 more?i'm thinking about it,but i'm not sure.some #'s would help.

 

Advantages to head MEGA flow at low to midrange areas on the curve. I've tried to maximize spool-up and steep torque ramu up to get me from corner to corner the head was the single most noticable mod for this. My Stage IV used to snarl off the corners now it leaps and roars! Had fun at a all EVO track day this week and instructed the new trackies..got pressed into a "time trial" (I hate these cause you only get two laps to get it right) on a track I've never driven on in a car with a blown viscus coupling (that's right 2WD/FWD with an open diff) was 2 seconds faster than the next closest EVO..thanks rich for taking it easy on an old man! I was peddling the car off every corner limited by inside tire wheelspin...and still trapped 2 MPH faster at the end of the straight on the radar gun... see why I love the Boys from Ohio? My normal full warp set-up is 24 lbs boost on 116/118 and I was running this "teaching" day at 20 lbs on 112 that means I was down 40+ HP and still had the "Ohio Hustle" corner to corner and down the straights! (of course the RRE JIC set-up gets me through the corners) I don't need dyno #'s just low lap times (fastest Lap in an EVO at 6 Southwest tracks, the Open Touring Car Challenge Class Touring -3 win (5 tracks in 5 days) and an invite to the SSC Ultimate Street Car Challenge is hard to argue with and WAY better than any dyno sheet to me!)

 

I guess I should have waited a little before getting the 272s. I'm wondering what some aggressive, high-lift, lower duration cams (JUN, Tomei, Piper) will do in conjunction with the BR head.... hmmmmm.

 

Me too. The piper Rally cams pkg looks really sweet. The lift is way higher then the JUN,TOMEI, or HKS offerings and the duration only 265
