Indeed Vinney, CP's are only really needed for higher boost applications and provide no performance boost at all.

BMW actually revised the charge pipe design from May 09+ 135i builds to a 1 piece design as it incorporates the elbow section. The problems I mentioned can still be experienced though. That being said, I only recommend changing the CP if you experience these problems already or plan to run big power in the future. Or you could always get some electrical tape and tie down the DV's

Tbh, for most daily cars, it's probably not necessary unless you are already experiencing boost leak.

Imo, reasons for upgrading in order of priority:

1. You'll be visiting the track or enjoying spirited driving and want peace of mind that your charge pipe won't blow off - potentially leaving you stranded or damaging something in the engine bay,
2. To eliminate boost leak,
3. You want to run meth, and/or
4. You personally like the sound of a blow off valve
Just want to requote this. Although, practically there probably isn't much difference.

I personally have the CP because 1M was known to blow off its CP, and whilst I am at it, decided to have the Froge DV as well for increase boost for later mods.

I love presenting complete data - so theoretically the CP may increase response due to the above reasons, but practically it might not be significant.

Vinney, have you got any delta on your IATs? Silly me haven't logged them before I changed it over.

A while ago I ran another 135i side by side to whilst we both ran some logs and my IAT's were significantly lower, the only difference being my FMIC too. It definitely works.

I don't think it's a case of IAT's being too high, but more so about keeping it as cool as possible to minimise heatsoak and improve consistency for back to back runs.

Was that with me Vinney? If so, I remember yours being at least 20degrees cooler...

Yes, that was you Rich. It was a while ago, don't really recall the conditions etc but the difference was quite noticeable.

Just want to say thanks to Florian at a-workx for all the help and information on my selection on the brakes. Good to see a company concentrates on weight savings rather than power with their mods. Looking forward for them to come in .

Thanks everyone!

They are very light though, close to 20kg savings in unsprung. Bang for buck I think they are much better than the akra.

5kg per corner? Surely that can't be right. Do you know the weight of the stock 1M wheels and these new ones? Are these in 19s? If the weight savings are accurate it will make a huge difference.

I still think the Akra sounds the best but you don't need to spend that much money to improve the sound. Even some N55 mids will do the job. I'm partial to louder exhausts on the N54 though

These wheels will look awesome, you will definitely have a unique looking 1M in Oz.

Yes they are in 19s. 7.2kg fronts, 7.5kg rears 19x9 and 19x10s. Someone measured the stock wheels on the M3 and they are 25.5lbs fronts and 28lbs rears.
http://www.m3post.com/forums/showpos...4&postcount=10

So, thats 4.4 x 2 = 8.8kg for the fronts, and 5.2x2 =10.4kg. Total savings 19.2kg of unsprung. .

Lol - weighing up my options. Will be deciding between KW, Ohlins and JRZ.

That's a huge weight saving. I'm sure you will notice the difference straight away, especially on the track
