Dinan is overpriced junk, and it hides under that veil of "BMW safe/warranty safe" when it, in actuality, is not.

The throttle body in our cars doesnt work as a traditional throttle (thats what valvetronic does) That being said, we have a throttle body, with an opening that is only so large; Dinans big-bore throttle would increase flow, although, that assumes that the throttle is the bottleneck.

Anything can void the warranty it is up tp the dealership to prove the mod is the culprit.

Dinan is the biggest waste of money...I would wait for some other products to show up...

[Hunter399]

I will probley get their software

The idea of keeping the same warentee is very appealing

[tl_boy]

Word. I can't believe the 330i stuff came first, the 325i has a lot more potential for modifying. I know Dinan is the only warranted tuner, they better not short change the 325i's full potential in order to keep BMW N/A happy.

Really want:
Intake
ECU retune
Throttle Body

!!!

[tl_boy]

I think the difference in the exhaust and intake systems between 325i and 330i is not as large as the difference the ECU retune can make. In other words, a 325i with solely an ECU retune should see the majority of the gain. Im no expert though, thats just what i am suspecting here.

werd! I work at an authorized Dinan dealer and every worker at the shop feels Dinan is over priced crap. The only time Dinan had respect was with the E30's and SC for the E36.

what's sc?

The only differences b/t a 325 and 330 is the intake manifold and software setting. I think the manifold (3 stages verses 1) will make more of a difference than software.

That's what Dave @ MotorworksWest told me as well. Speaking of software, I asked about that & he stated that BMW's programming is becoming more & more adaptable to the physical changes that are made (intake & exhaust). He didn't even know if Dinan will offer a reprogrammed ECU option available all by itself. Which would suck if they didn't....

The intake that Dinan will have replaces the airbox and the piping in front of the airbox, but the manifold is left alone. The 3-Stage intake would supposedly adapt itself to the increased airflow.

[sixspeedsam]

What kind of real world gains are to be expected from the intake/exhaust? Or are we just talking asthetics and a nicer tone?

Does Dinan or a rep normally provide dyno results for folks to inspect and pick apart?

Would be nice to just chip and gain some noticeable HP/TQ with it ala my old A4 1.8T. Damn N/A engine

Oh god, Strazz is on here...hide the women!

Ryan, dont forget about the Dinan twinturbo 850CSi!

there is no throttle body in the traditional sense in our cars

I guess you could still put a bigger hole on though


seems pretty dumb to me

[voltron1011]

Hmmm... 1500 to 3000 bux for an extra 7 to 15 horsepower (and I'm being very generous)? Nah....

[hkj]

This could be interesting. I'm curious to see what Dinan comes up with for the E90.

I like their current ligh-weight 19 inch wheel and tire setup and their Brembo BBK. They sure are super expensive though lol..

it is warranty safe, if you have the work done at a BMW dealer

if you do it in your garage...............

[sdbcerda]

I had the Dinan freeflow exhaust on my '99 E39 528i and loved it. I had it installed at Dinan, met Steve, and got a tour. I am impressed with their products even though they are expensive.

[bavarian19]

If they offer something great for the 325, I would be interested... There is great potential with the E90, and I wouldnt mind paying a few bucks if they can offer some good power gains...

[Artz 330]

its warranty safe because the gains are low to non, that they wont cause any harm lol. Dinan is Junk!

[shragon]

i used to think to that dinan was over priced. after receiving a tour of their morgan hill, ca facility by steve dinan at their 25 year anniversary event, it changed my perspective. i was pretty impressed. i have great respect for what dinan has done for the bmw tuning community. they put a lot of r&d time into developing products. although, i still feel their products are expensive, and that there may be some better alternatives out there, i won't go as far as calling their products "junk" or "crap". i'm looking forward to seeing what they came up with for their intake, as the majority of the aftermarket intakes i have seen so far are not very good at all.

[tl_boy]

so change out the intake manifold, and voila? 215 to 255?? ECU adapts? I can believe that, I remember in the olden days, you would disconnect your battery and then the ecu's would automatically adjust after a performance part was installed.
