Dinan V10 Throttle Bodies

[SteveBreen@dinancars.com]

We’ve heard about difficulties with our V10 throttle bodies, particularly how the product has had defects and people’s cars have spent long times in the shop during installation. After checking into it, the problems have all been installation errors. The installation follows a BMW procedure, but many technicians are still struggling with it. To reduce the instances of this in the future we have rewritten the installation instructions, adding steps to the BMW procedure outlining the common mistakes. In addition we have listed the faults that get set when the throttle bodies are installed incorrectly and indicated what causes the fault to make problems easier to troubleshoot. Since this change, the instances of problems have greatly reduced. We were pretty confident from the beginning that it was not a manufacturing defect because every throttle body is flowed on a flow bench and matched as a set.



Lastly, and on a completely different note, I want to thank those of you who’ve been messaging me with Dinan-related questions. I’m a new intern at Dinan, and a mechanical engineering undergraduate student. My primary responsibility here is to post information for you all and to be available to answer your questions. Often times I won’t be quick to respond because I’m still in the learning process, and Steve Dinan is usually by my side when I’m giving anyone information. If you need immediate response, our tech line is your best bet (1800-341-5480). Nonetheless, keep the questions coming, and also keep an eye out for tech articles that Steve Dinan and I will be writing in the future.


Thanks!

I think you may have opened a huge can of worms. So the defects have all been installation oriented? Does that also explain the inability of others to recreate any horsepower gains on dynos (per multiple board members)? Or is this just an explanation for faults that are occurring?

Duck and Cover! I am not sure what sound airborne rangers make, but whatever it is, I think I hear it coming!

Would be interesting to see the flow rates of the Dinan Throttle Bodies compared to stock and corresponding dyno graph substantiating those gains.

Hopefully not. I think what's needed to be said has been said. I'm glad
that Dinan has a representative that is here to answer questions and
concerns.

LOL. Here come the black hawks (wop, wop, wop, wop, wop)...

Thanks for the update. We are all interested in spending money on products that provide real world gains and can be verified. The more evidence that can be provided to support the value of these products the better.

As a board community we try to assist each other in proving out various products. Collectively we can gather a lot of information and help fellow members to buy the best mods.

To the extent that you maintain a presense on the board to answer questions it will be very helpful. Welcome to the board and keep the posts coming.

Oh boy...here we go again

But no explanation as to why the ones that ARE correctly installed are not showing gains?
