This weekend I got to test drive a demo Dinan M3, more mods than I can even remember that added up to a $45,000 aftermarket bill. 425 hp. I really don’t know what to say other than WOW, what a package, and so smooth it felt more like a fast factory car, very impressive.

Anyway, I did talk to the rep about when and what they had planned for the e90. First up cold air intake and exhaust. He said that the factory intake was very restrictive and almost all of the gain would come from the intake mod. Which is all making sense now as far as marketing, 325, 330, 335, M3? They need to create a gap in between these products, so what do you do? Detune the products lower on the list on boost the ones high on the list.

So what does this mean for us, about a 30hp gain for the cool air intake alone and only 5 hp on the exhaust. That is without removing the carbon filter, which he also said was very restrictive, but they were leaving it for CA emissions. Timing: September.

30hp for intake alone seems like a lot, but who am I to argue? That is all I have, no more let out of the bag. But you have to wonder, will a chip (the right chip/remapping) actually really be significant for the e90, I think it might, especially with the 325

Thanks for the info. Lots of people talk about factory detuning, but it doesn't seem logical that the company would extrude hone the intake manifold for added gains, then take those gains away by restricing the air intake.

We do know that the US E90 325i and 330i have different induction systems--single stage vs triple stage respectfully.

Time will tell on the numbers. Supersprint will soon be releasing their headers back exhaust system for the American market, and I'd be willing to bet you'll see much more than an additional 5 wHP from that. 5 HPs extra at the wheels would be an only 2.4% increase, and the existing aftermarket E90 systems are already claiming more than that.

a 30 HP gain sounds a bit over confident

I would expect 10 AT MOST

I am still getting the Dinan intake no matter what

Ditto. 10 for the 325i, and probably less for the 330i, which is already fairly optimized with the 3 stage manifold.

No intake is going to give you that much HP lol. Did you get any info on how they plan to set up a CAI on our cars. There is no room in the engine compartment.

finally dinan is makin somethin!! THATS GREAT!!! Do you know how much its gonna cost for the cold air intake?

[Ryan.M]

If Dinan's SC for the E46 M3 only gives about 75hp how can an intake give 30 hp?? Dinan needs to buy a new dyno.

My guess would be $1200

and people will still buy it because of the warrantee thing.

maybe they'll set it up like the touring cars and have the intake coming from the front grille?

[EVO_S4]

30whp I be first on the list, but I doubt it

[Hunter399]

Maybe from the brake cooling ducts

Okay, I am just the messenger here. He did say that it had cold air intake, but he did not mention from where. I know the 30hp seems a little crazy, but that is what he said, and he went on to explain the issues with restrictions and that the 5 series has the same issues, but they were able to get the 30hp out of it. He didn’t mention price but I can’t imagine it being more, or much more, that the e46 version at $399.00 USD. Heck 15hp would be pretty impressive, then removing the carbon filter for better throttle response, sounds good to me. And the warranty coverage is worth a little extra, cheaper than paying for a major repair they somehow link to a air filter.

No need, they will just buy more marketers!

At this point, you buy Dinan because of the name, not because of the performance.

[Ryan.M]

I look at it this way. If the guys in Germany dont use Dinan then why would I

In Dinan's defense, they don't market to outside of the US and Canada.

I wonder why.....

Competitors, logistics, and market size? The usual business drivers. Doesn't mean that Dinan is bad. Also, the most popular engines (1.8L, 2.5L and 2.5 & 3.0 diesel models) aren't even sold here. R&D would be expensive. Note that for the rest of the world outside of the US and Canada, 3.0L engines are relatively more rare because of taxes based on fuel consumption.

30 hp from an intake is very wishful thinking. still looking forward to see what their new products look like.

I would agree but I'm willing to wai for the Dinan intake. I just do not like the design and look of the intake in the market right now. I will buy Dinan intake regardless of price.

It'll probably run around $1599.

after the fajita incident, im very uneasy with small name brands..which is why i think ill go with dinan even with the steep price...they actually research and develop unlike some companies which toss all their products into a kettle and stir...
