My purchase of a very early 2015 Harrop from DrFerry went very smoothly with no issues, but the install has not gone well after the initial install. Intial install was completed in a day and car was idling fine. I should say just a couple nagging issues persist, because car starts and runs fine, albeit pegs at a steady 4 psi and small but noticeable breakup from 5-6K rpm. Install is being done at my local shop Performance Technic and lots of support from Mike at BPM. They have installed quite a few of these kits and this is the first one to exhibit such issues. Mike has sent me a new Harrop controller but unfortunately this did not help. They have checked three ways to Sunday for a normal so to speak "boost leak" and can't find anything. Manual boost gauge builds boost to 4psi nearly instantly on WOT and just sits there to redline. Electronic BOV has been recalibrated numerous times. Needless to say this is draining by wallet like a thousand paper cuts and yes more than a new kit would have cost now. I don't need to hear about that, but would love to hear if anyone else experienced a similar issue and what solved it. Thank you!

The question is why can't boost continue building beyond 4PSi?
DrFerry Do you have any old dyno sheets? |
Yes, that is indeed "the" question. regarding Dyno sheets: possibly so on an old computer. I'll see if I can locate them. I recall the shop measuring wheel horsepower, torque and AFR, but I'm not sure if the shop monitored boost when those Dyno runs were made? PS: that shop is now out of business.
My feeling is there is a boost leak or the bypass valve is not being closed completely. |
I just spoke with Chris the manager at Harrop USA, and he feels the EBOV is not closing all the way and the threaded rod must be adjusted. Just a guess though. He also mentioned that with my "Open" exhaust that I may not build 6.5 psi of boost. I would like to hear from others that have cat delete free flowing exhaust's to see if this is indeed the case. |
Agree with
DRLane boost leak is a concern. On my first install, I had a throttle body boot that was folded over and leaking on my Harrop setup. I'd get boost up to 6.5 psi (p3 gauge, boost
measurement displayed digitally) but the boost would immediately fall off. Very hard to visualize each boot unless you are inspecting with a flexible fiber optic camera. I picked one up for $50 and it's been handy for other jobs.
You also want to calibrate/zero your boost gauge if not done already.
When I moved the Harrop from my e93 to the e90, I had to replace 4-5 of the throttle body rubber boots. all my boots were properly aligned on the Harrop this time but discovered that one of the metal crimp bands holding the boot on each individual throttle body wasn't tightened properly, and that was causing boost leak. The boot stayed connected to the Harrop unit and pulled right off the engine when I lifted it up to inspect. I think throttle body is technically an incorrect description but I'm referring to the piece feeding air into each engine cylinder, and the rubber boot bridging that piece to the plenum or supercharger unit
Lastly the worm-screw hose clamps seem to loosen after the initial installation and I find that they need to be re-torqued to spec 1-2 weeks later.
