if you look, most of those postings are through staffing agencies.... not many firms bother screening themselves these days

well i tried helping. guess ill go stick my head in the sand now.

whats goin on peoples.


Happened to see a lovely AW/Fox red E92 M3 today out in bellmore..with CF roof.

Why the heck is everyone orderin them in AW now? Seems to be the new silver these days.

I think 95% of ppl have them in AW...

Its nice but a bit plain IMO.

Damnit just when I was about to get one of these intakes, I found something that tells me it's a bad idea.

damn just when I was about to get procede V3 and my user friendly DIY boost controller.....peoples turbos started going kaboom



I was giggling like a buffoon when I was reading all that stuff happenin in the turbo section. Sooner or later people are going to find out these turbos aint all that.

Hell half of these people here dont even know how a turbo works.

Dude if you like them then get them. who cares what bunch of haters who cant afford them think

Nah it's not that. The two intakes I was looking at both have temperature issues. It seems the only one that doesn't create an increase in coolant temp is the UR CAI. I like the effect you get from the filters, but I don't think it's worth putting extra strain on the engine and turbos.

The turbos on our cars are real small. They're about the size of your fist lol. Personally I think BMW should have gone w/ the sequential turbo setup like they have on the 5 series diesels. One small turbo spooling for low rpms and then feeding the big turbo for higher rpms.

what kind of effect would someone get from those filters?

and i will be the first to admit i dont know how a turbo works. which is why i dont want to screw with mods for the engine unless i know how it works.

You are a very smart man my friend.

Evidently both the BMS and K&N dual cone filters have an increase in IAT over the stock airbox. While it's not that big of an increase to be considered heat soak, the temperature rise is more evident when driving daily, up to a 70 degree Celsius change on a 3rd gear short WOT, which happens pretty often in daily/highway driving. While the sound difference w/ the diverter valves and the turbos spooling up is sweet, personally I don't think it's worth putting increase strain on the engine.

I don't know how all the turbos work fully, but I found that pretty helpful.

[itsbrokeagain]

letting the turbos breath easier is actually not hurtful for it at all.

The problem lies in the turbo itself. The turbine is extremely small, and if you free up resistance before it (the airfilter) and after it (catless downpipes and exhaust), the turbo will love you for it.....to a point.

The exhaust gases tend to move much more rapidly at this point....which is still good for the engine, because the faster you can expel burnt air, the faster you can inhale more...and the more power you can make.

The real issue is that the turbine is just simply not designed to cope with the extra speeds that come along with increased gas velocities....most OEM turbos hover around in the 90-100,000 rpm range...which, because of their small size, makes them easy to spool early, makes lotsa torque, but it runs out of breath in the midrange...which is why all the stock cars feel like they die out around 5500rpm....

at this point the turbo is spinning its max..and spinning it more will not make more boost..only heat it up a lot more, causing the turbo compressor to lose efficiency...this is what we turbo guys call the choke point....meaning you can keep spinning that turbo and trying to make more boost, but each lb of boost you make is almost negating itself due to the really high temperatures coming out of the turbo going to the intercooler...and being the stock intercooler is usually only good for 13lbs of boost, anything more than that is just more heat getting passed on to the engine.

And as we all know, heat is the enemy of the engine....it kills things, makes things run slow, suffocates, etc.


When you push the turbo to 15lbs of boost, you are spinning it to frightening levels...150, 200,000rpm or more. The bearings inside the turbos just arent meant to deal with the speeds and the centrifugal force on them...which is why they crap out after a couple thousand miles.


I get scared when I see people running 15lbs steady all day long and people spiking up to 22lbs or more....in the turbo world on a regular engine, thats enough to pop a rod through the block, or have the turbo implode, filling your engine with aluminum shavings if you use a tiny ass turbo.

[itsbrokeagain]

now if we put a BIGGER turbo on the car, say one with bigger turbines that flow more, then we wouldnt have any problems. When you ease backpressure out of the turbos, exhaust gas temps go down and the turbine operates more efficiently.

A bigger compressor would help as well. Most larger compressors over stock, will move the same volume of air, for a lower boost. So there for you could make the same 350hp on 9lbs of boost with a larger turbo, instead of trying ot cram 15lbs through this little tiny one to make the same 350hp.

The turbo does less work to net the same horsepower output....and with lower boost comes lower intake air temperatures....which means the intercooler can do more work to cool it down and not get heat soaked, which means cooler air for the engine..and cool air as we all know is great for engines.

[itsbrokeagain]

sorry thats just my little bit of turbo 101 for the evening

[Dragonman4]

Larger turbos would create more lag right? Because it takes longer to spool. Hence like the Evo, before the turbo spools the acceleration is terrible. A sequential on the other hand seems like a good idea. Small turbo to spool for lower revs, and bigger turbo that spools at higher rpms. Although apparently the issue is with the intake air temps w/ the filters is resultant from the increased turbo heat.

[Dragonman4]

Dinan technically already has a setup that makes more hp than the M3. Too bad the whole setup costs like 10-12k

mornin people. I'm off to Philly to start clearing up my apt. Have to return the cable modem and box or they'll fine me lol. Comcast FTL.

its simple... gas + air + waaaaaaaaaaaaahpssssssssssh= car go fast









morning fellas
