DINAN Throttle Body vs Stock Comparison - Page 2 - BMW 3-Series (E90 E92) Forum

///Matt · 03-23-2007, 01:41 PM

I thought it'd be interesting to note...

The N52 produces almost zero manifold vacuum. It actually has to use a vacuum pump, run off the timing chain, to produce enough vacuum to run the brake booster and the exhaust flap.

SE3P_to_E90 · 05-01-2007, 10:10 PM

what would be the approx. cost of buying and installing this unit? i.e. Unit cost and labor...

any updates?

SE3P_to_E90 · 05-03-2007, 06:26 PM

no updates?

I intend to go back and redyno. I realized (after) that when I last dyno'd, my tires were very low in pressure. Not sure how that would affect the outcome, but just so that we're comparing like pulls, I'd like to have it rechecked.

This is not too difficult to install. Just four bolts attach the throttle body to the intake manifold.

SE3P_to_E90 · 05-03-2007, 06:35 PM

Just out of curiosity -- and i don't see why it would pose any problems (but just to make sure), will this mod work flawlessly with other intakes? i.e. GruppeM or something else...

Lastly, in regard to the ECU's ability to learn and adapt, after the application of these mods -- do we have to reset the ECU (i.e. disconnect the battery)?

I know it's ideal for you to do this after all mods, but just wondering...

Hunter399 · 05-03-2007, 06:53 PM

Im so tempted to do this mod

I probley will this summer

Fascinating!

I also find the electronically driven oil & H2O pump techno wizardry....Did the E46 engines include this as well?

Matt your a good technical resource

DEMENTEch335i · 05-25-2007, 05:55 PM

Anyone knows if this dinan throttle boddy it's the same for a 335i?

Eastmeetswest · 05-25-2007, 10:35 PM

why dont you just post your dyno results with your screwed up tires-that does not effect a dyno time unless your tires were completely flat-either way will give us some idea. They must have been no better or else ya woulda posted them

SE3P_to_E90 · 08-03-2007, 06:13 PM

yea... no gains on this whatsoever?

Any word? Is this something that will increase some performance in my Bmw 323i?

I'd be interested too. It's been a while since this thread was posted, any results yet?

letterkills155 · 12-12-2007, 02:55 AM

he lost power why would you do it

Wlew · 03-24-2010, 08:39 PM

I am wondering what you think of the throttle body... I read most of the posts dated a few years back, but they started to lose me.

Is it worth buying? and how much gain did you see?

I have an afe intake, scoops, and bms pbx. stock exhaust.

wondering if the throttle body will help with throttle response, sound of the exhaust, and gain any hp or tq.

p.s. if you have a dyno I would love to see it

msrothwell · 03-25-2010, 08:59 AM

I think it'd be cool to see a slide throttle body for the N52. The main trouble with a Slide throttle is part thottle performance but with a throttle that defaults to open, all of the advantages would be there, less restriction for a given TB size, resulting in higher intake velocity, and hopefully more power.

BlackBimmer1991 · 03-25-2010, 11:07 AM

is it avaiable for the 328?
