Maybe if I tracked her I would consider some test pipes, but even then I would just go with the Akra Evo full exhaust!

I totally understand the desire to keep the noise down on the M3. One of the things I love most is its duality: luxuriously quiet at cruise, performance mean at WOT. I understand the desire to maintain that. And I say that as someone with the Akra Evo on his car.
Anyway, the discussion got off track a bit. How easy is it to swap the Dinan pulley yourself for someone with modest mechanical ability? Will any pulley DIY work? For example, I believe AA makes a good DIY for its pulley. |

I’m sure any pulley will work, however I myself would only go with the Dinan pulley kit. It’s backed by Dinan’s industry leading 4year/50,000 mile warranty so I know it’s the best quality product for her. Which gives me peace of mind; therefore if something were to go wrong it would be backed by my warranty.

The comparison is really 20>0, since the pipes give power immediately whereas the pulley doesn't kick in till the very top of the rev band. For daily driving, pulley does nothing (although some people say it makes the car run more smoothly, which is a subjective result I have seen attributed to everything from DME tunes to Euro DCT coding to air intakes). In daily driving, the pulley does nothing, where is the torque from the pipes is immensely useful. Voided warranty with pipes? Of what? The dealer is far more likely to void your warranty over a pulley, which is a direct modification of your engine and every accessory being underdriven. And it's funny you bring up cost comparisons, considering the sound of your $2500 exhaust can be replicated/surpassed with a $200 ACM mod. In conclusion, what you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul. |

First and foremost I would like to take the time out to thank everyone who contributed to this thread regarding Test Pipes! However, as the title states, this is a thread about an underdrive pulley kit (the Dinan Underdrive Pulley kit to be exact) I never once inquired about test pipes nor am I interested in purchasing or running test pipes, I’ve already purchased the exhaust system I wanted. The question at hand was/is about the Dinan underdrive pulley kit which is backed by Dinan’s industry leading 4 year/50,000 mile warranty!
Matter of fact here is my original post: I’ve been thinking about purchasing the Dinan Underdrive Pulley Kit for it claims an additional +11 horsepower @ 8400 rpm and +7 lb-ft torque @ 8400 rpm. For all who have the Dinan Underdrive Pulley Kit how do you like it? For all that are running another brand of Underdrive Pulley kit what are your thoughts on it compared to the Dinan? Do you feel it makes a difference? Thanks in advance, So to all my test pipe junkies, thank you all for coming out God Bless & Good night!! Now let’s get back to the regular scheduled program……

11 horsepower out of 414 = 2.7%, at 8400 RPM. And this is "claimed" gains too. Talked to a few people and they said if they could do it again, they wouldn't bother.

If I could do the pulley kit again I wouldn't hesitate to do it. You'll notice no difference with your accessories running. I keep my A/C blowing cold (Hot Ass H-Town....I don't have a choice) and my temps are as normal as the day my car came off the boat. I say go for it and don't look back............Phil

I mean if that’s the case everyone who goes out and buys the Akra Evo for $6,000 might as well get a supercharger instead. I mean 150hp > 25hp (simply a rough estimate) & 50lbs weight savings right? I mean if we’re calculating % to hp ratio per dollar spent! I’m not trying to convince anyone to go out and purchase the Dinan underdrive pulley kit, I’m simply inquiring on the product so that I can decide if I would like to purchase the Dinan underdrive pulley kit for myself. Again I respect the opinions of all those who have chimed in regarding test pipes, I appreciate the input!

A couple of us told you about the pulleys. I know of a few guys that said they probably wouldn't buy another if it was up to them. But you seem to really want it, your money, so go for it. And if that's the case, not sure what else we could tell you that hasn't already been said.

The dealers in the Bay area have zero issues with Dinan mods...maybe because they're a local company, but I don't hear of many Dinan mods being challenged by dealers in any location. In 1-2 instances when there has been a dispute, I have heard that Dinan totally stands up to their warranty on both the part and any perceived causal effects on other components and will cover those. Actually Dinan will even talk to the dealer and try to work things out (they have a great relationship with BMW) and if that fails, Dinan will step up (reputational capital is extremely important to them). Pretty good peace of mind if you ask me, and yes I would do the pulley over again... it is more top-end oriented in terms of hp gained but isn't that where all the fun is anyway?

That being out of the way, you are quite welcome, and I hope you will enjoy your pulley. P.S. Technically, Dinan's warranty is not 40,000/5 years, but whatever remains of your factory warranty. If you are out of warranty, they will cover it for two years from date of purchase. |
