    [Closed] Borg Warner Efr Series Turbos

    in Forced Induction Performance

    In the past, if the turbo stopped making power, that'd be where you'd have stopped as it would be out of its efficiency zone. The turbo speed didn't seem so crucial as you would have stopped prior to the limit or the limit is much higher and/or not catastrophic immediately.

    With the EFR's and the combination of E85, the rpm limit appears to be an issue.

    True, but but personally I agree with Harris Racing, just because you can doesn't mean you should. BW give plenty of accurate data, eg. Comp maps, max shaft speed, matchbot etc so it would naive to ignore it and complain about a failure.

    its just that ignorance has become the norm, and people spin most turbos well beyond they're design limitations because on fuels like E85 they continue to make power with added boost. Yet a step up to a properly sized unit will generally have gains everywhere, and stay reliable too lol

    My On-going Dispute With Recent Fines I Received

    Wow, for someone on here for such a long time to have posted just once, you must have had to build right up to your very first time, what being so helpful and all. You come across as the typical engineer. Zero people skills, minimal application, no clue.

    Just take the time to go back over the first post, being the obvious target for your clever deductions from ADR's and consider if Qld Transport might or might not have clarified whether (note spelling, the other type is a nutted sheep) they have a specific concern over vented BOVs. Try not to let your obvious superiority by being an engineer cloud your judgement or ability to read. Take notes if you must.

    Just so you know, states generally comply with ADRs but must specify their own particular requirements (which can be as simple as stating the ADR or making their own up), hence SA does some things a lot different to say.... Qld. So if Qld Transport say they don't care about atmo BOV then that is what the various elements of the compliance arm must abide by. They cannot decide to commence their own vendetta.

    As for the noise compliance, the compliance officers must test for all elements that have a specific test associated and not just make a guesstimate, so in this case a driveby test which if memory serves is rolling at 60kmh through the start of the run in third and then flooring the accelerator and travelling the prescribed distance......nope the BOV won't vent for this test. Sure they can have suspiscions but that usually gets reported through Qld Transport/VicRoads etc. They then issue the order for the vehicle to attend testing. They don't run driveby tests as a rule because the cost outweighs the benefit.

    So thankyou for your highly educated opinion, but some of us here are also engineers and possibly (probably) much better at it than you. This is not the place to get in a pi55ing comp but believe me when I say you will depart embarassed.

    You may continue lurking. There you will trouble no-one any further.

    With people like you on a forum, what is the point of continueing. (Since you clearly have better social skills than me) :ninja:

    Oh for the record, you are very inaccruate in your descriptions and posting. Would pay to query something other than jumping up and ranting on in some attempt at looking intelligent and contradicting the whole reason for you post to begin with.

    Amazing how a car enthusiast based internet forum, has so many people who have little or no knowledge in relation to cars and modifications.

    The fact does remain that all vehicles must comply to national vehicle standards, that includes modified vehicles. ADR's ring a bell

    This is where the blow off valve situation comes into play. (obviously relates to later model engines, check the dotars site for relevent ADR's)

    BOV's vented to the atmosphere on vehicles which have these ADR's are illegal, and you will be fined.

    It goes against two ADR's listed below. Just to note further, any air that enters the engine through its induction system ie(turbocharger, airbox) must exit through the exhaust. If you want further details on this, gee I dunno contact an engineer. (For the record, I am an engineer)

    Not being plumbed back has the following issues

    1. It vents crankcase gasses to the atmosphere - Against ADR 79

    2. Increases the noise level/induction level - Against ADR

    I think people should start doing some research before assuming their modifications are legal, then starting topics on internet forums crying about their defects. Wether they like it or not, most of the time the police are certainly within their right to give you defects. So remove that possibility by making your vehicle legal, might be a good start

    You can mod your car correctly, and follow the guidelines which are there for you, get 0 defects, or go ahead and think you can outsmart the law. I know which path I will follow.
