[@jasonsinaga2217]

Where do u get the throttle body? Send a link please because theres so many options idk which one is the correct one i have a 2003 330

[@MindHunger]

Great video, thank you! Did you see a difference in gas mileage with the underdrive pulleys?

[@joeycrf50]

You're in bend or! Been down those roads many times!!!

[@robbya6113]

Do you know the torque specs ? Especially for the alternator pulley bolt? I haven’t found a torque spec yet

[@rafaelricogarcia9550]

What is this screen in the vent gauge? it's cool! I need this!

[@rayhanabiyan1526]

the vent gauge is really cool man where did you buy it? also cool video

[@andyalexis8180]

Did you have any issue with installing the alternator pulley I’m currently trying to put mine on and it’s giving me some issues

[@jmerodgers]

I would think the ambient temperature would have more to do with the difference in performance. Im not sold that the pulleys do much at all. They are nice quality and look good but ive had them on my previous e46 and honestly didnt feel any difference. I think i saw that you had an intake installed? The Dinan system looks good...I think i might be inclined to spend my $200 on that instead? Your thoughts?

[@TheFullLouie]

it was such an uncontrolled before and after, I'd say that there is little data (based on my to actually say they make a difference. The car does feel like it has more low end and revs up more freely at the top end. Feelings are anecdotal however. The dinan intake was my very first mod. many years ago. I don't think Dinan makes the same intake anymore. The one I have pulls air in from the brake cooling duct under the car. The filter sits just behind the driver side fog light. The new ones have the filter sitting in the engine bay. If you do the intake you need to do the software too. once you do both you're looking at over $400 so cost comparison isn't fair. if choosing between one or the other? intake and software. hands down.

[@SydeshowMO]

His intake temp was around 104 at idle I think. My intake temp at idle is 140 and 112 WOT at speed. So that Dinan CAI is for sure doing a good job.

[@Willielee43]

I have them on my 2001 330ci no issue. The only thing I can say my power steering is a little flat but I’m happy with them. I feel more on top end more pull for me.

[@billib1547]

Yooo on my 01 530 no matter what it still pulls like it could just keep going lol its scary at times

[@akdomun]

What do you mean your power steering is "a little flat"? Like you've got less feel or is it just harder?

[@Willielee43]

@@akdomun I found my steering rack and power steering reservoir was going bad

[@ollyyung5673]

does the dinan throttle body help much? considering this mod but have heard mixed reviews about it due to how little the differnece in mm the dinan throttle body is.

[@TheFullLouie]

It’s a bit snappier but it’s not going to blow your mind.

[@peligro3mw]

Did you have clearance issues with the pulleys and the expansion tank????? I’m currently have issues with no clearance , I also installed a high performance rad witch is a little thicker than stock

[@TheFullLouie]

Nope. No clearance issues. Good to go.

[@saiffyzy]

I had this issue and you have to pull your radiator towards the front

[@aaronhuynh3360]

BRUH What is before and after times 0=60

[@comecorrect8365]

Surprised you got the original power steering pulley without it cracking or splintering. Old plastic always sucks.

[@CiscoKidd055]

What was your initial 0-60 before pulleys? you had 7.01 after but no before. Been thinking a doing this myself.

[@dougburg3210]

he showed 7.17 a bit earlier. .16 difference is not bad.

[@Blacknighxbox]

Lol i get 5.1 sec 0to60 on my 330ci

[@SzymonKasperczyk]

@@Blacknighxbox in your dreams

[@Blacknighxbox]

@@SzymonKasperczyk lol add me on my ig i got videos of my draggy if u think is cap m54_ricky1320

[@SzymonKasperczyk]

@@Blacknighxbox just point out you are reffering to heavy modded car next time, lol. 6s' would be fast for NA in this power/weight ratio. 5s is very fast.

[@armandoarriaga5526]

Why don't you have the fan for the fanclutch ?.. wont it hurt the car since the fan keeps it balanced out ?..

[@SydeshowMO]

Probably swapped in an e fan from manual trans car. Manual all came with an e fan.

[@georgiageorgia7911]

It,s work ?

[@TheFullLouie]

Not mind blowing, but it seems to rev a little more free at the top end. Not sure I'd do it again except for simply knowing I've maximized what I could.

[@clivebruce7334]

Stage 3

[@henrylj2660]

man I want a smaller pulley for power steering

[@TheFullLouie]

Don't know if I'd do it again for the money, but haven't had any issues since install. Plus it was fun/easy to do.

[@SydeshowMO]

Anything done to an automatic is pretty much a waste, no?

[@DiegoFlores-sx7nr]

No way jose ... bmw automatics transmission are good af ...!

[@SydeshowMO]

@@DiegoFlores-sx7nr yeah for commuting in traffic

[@christophernuckolls9964]

No.

[@Turbo_The_Femboy_Fox]

@@SydeshowMO fun fact, the new M5 and M3s have automatics, planetary and everything. The same design of auto as the e46 Autos. Plus the M5s and M3s shift faster than manuals.

[@troydbarney]

You should just get an M3. :)

[@user-qd1zk7kj3d]

Does an m3 have 4 doors ?

[@xninjasurfer]

@@user-qd1zk7kj3d yup i actually have a 98 m3 sedan
