Update from Racerbruce....

[racerbruce]

Greetings fellow BMW colleagues -

-I abhor the screaming yellow warning labels.
-Some have tried heating/removing the labels unsuccessfully (damage to sun visor).
-Found a clean and easy solution.
-Peel & stick carbon fiber look tape.

Performed this on my Z4M Red Roadster (rest its soul).





Regards to you -
Racerbruce

Cool!! Where can I find that tape? I hate those labels too!

[wdb]

I think grannyknot has a way to safely remove those labels.

racerbruce I am dubious about that air intake mod. All those do is suck in hot air, and hot air robs horsepower. Perhaps they make some sound?

Perhaps you can take a moment and review the dyno test results and the link to "Click Here for Hot Intake Air Myth Testing".

Comes in its own re-openable container, with a yellow "scraper" to assist in removing bubbles and enhancing adhesion:

Those labels are easily removed with Methyl Hydrate (wood alcohol) or probably ISO
Just an old tooth brush.

Hey RB, what's the butt dyno saying on this mod?

They're using tuned engines, first of all. Peak WHP 350? The car has 306 crank horsepower from the factory. So perhaps on a tuned engine the stock intake is a restriction. Secondly the P-car forum is filled with evidence of underhood cone air filters robbing power, some of it from dyno tests run by the best engine folks in the country. Thirdly, and this is just my suspicious nature speaking, it is pretty easy to game a dyno result. There are correction factors applied to account for atmospheric and other ambient conditions, just for one example; all a vendor needs to do is fiddle with those and, presto -- gains appear.

Not that any of it matters much in our realm. Enjoy the noise it makes!

Just finished it and haven't had a chance (yet) to "exercise merging on a long onramp"....

-The BMW published data for the 335is N54 is 320 HP and 332 TRQ with a 370 TRQ available for 7 seconds.

-"The 335is uses a higher performance version of the N54 engine, which increases boost from 8.7 to 11.6 psi (0.6 to 0.8 bar).[49] This results in 239 kW (320 bhp) and 450 N⋅m (332 lb⋅ft) of torque, plus an overboost function raises torque to 370 lb⋅ft (502 N⋅m) for up to 7 seconds."

-Send the link or perhaps a copy of the info stating the 335is N54 produces 306 crank HP.

-To correct the inevitable failure of the plastic OEM chargepipe, ordering a number of upgrades including an aluminum chargepipe, removal of OEM diverter valves and replacing with a TiAL blow off valve, installing a JB+ software upgrade that is plug & play and connects to the TMAP sensor and does not affect the OEM DME that is already upgraded for the 335is N54 and this upgrade will increase boost measurably and has the ability to make boost increases on the device, proactively replacing the weak link of the plastic PCV valve with a billet aluminum PCV and replacing the blow-by pipe with a new OEM unit for safe measure and installing 2 step colder NGK spark plugs to accommodate the mild boos increase. Ordering the parts and plan to install the first week of May - this should be FUN and this will certainly be a mild "tune" for the Red Rocket.

Greetings wdb,
Perhaps you found the 306 crank HP info from this link or from another source which is for a 335i model https://www.auto123.com/en/news/the-...-306-hp/31523/ This marvellous engine produces 306 horsepower.

My model is a 2013 335is and was produced for the North American market only between 2011-2013 https://en.wikipedia.org/wiki/BMW_3_Series_(E90) The 335is was produced in coupé and convertible models for the North American market. Its position in the model lineup was between the regular 335i and the M3, and approximately 4,500 units were produced. The 335is uses a higher performance version of the N54 engine, which increases boost from 8.7 to 11.6 psi (0.6 to 0.8 bar).[49] This results in 239 kW (320 bhp) and 450 N⋅m (332 lb⋅ft) of torque, plus an overboost function raises torque to 370 lb⋅ft (502 N⋅m) for up to 7 seconds.

To make the 335is a track-worthy vehicle, BMW upgrades the cooling system with an additional radiator and beefs up the engine mounts. Inside are standard sport seats, steel pedals, an M Sport steering wheel, and textured aluminum trim. Between the seats sits the familiar six-speed manual, but it’s modified here to have shorter throws. For those who prefer not to shift for themselves, BMW is offering its seven-speed dual-clutch gearbox. The DCT system is identical to the one in the M3 and comes with steering-wheel-mounted paddle-type shifters.
Exterior styling builds on that of the 3-series’ 2011 freshening and adds an aggressive M Sport body kit. The kit has a more aggressive front fascia that ditches the coupe’s fog lamps in the interest of increased cooling capacity; the 335is convertible keeps its fog lamps. (And just to confuse you, we posted photos of preproduction coupes with fog lights; the decision to ditch them apparently came after these cars were built.) A new rear bumper incorporates a diffuser-style piece, and the twin exhaust pipes are finished in matte black. New gray-painted, split-five-spoke wheels are the only change to the chassis, despite the extra power—there are no tweaks or modifications to the suspension or brakes. The exhaust is a modified sports exhaust and not the standard BMW sports exhaust. According to BMW, they removed some of the fill to change the sound and also added a valve like a standard exhaust to control the noise where the normal BMW sport exhaust doesn't have this. The 335is exhaust differs from the 335i, 335i with M kit, and BMW branded aftermarket sports exhaust.

Apologies for missing the 335is designation -- that's a nice bump! However again you're talking about horsepower at the crankshaft. Dynamometers measure horsepower at the rear wheels. Losses occur in between those two places.

But so what! Enjoy your beautiful cabriolet in any way you please. Life is short.

Amen wdb - thank you.

I am so grateful that this uber-low production BMW is meeting and exceeding my fun-o-meter expectations after saying goodbye to the beloved Red Roadster Z4MR this past Oct.

A well known poster on the "3" series side of our website says that only 17 were produced in Crimson Red/Saddle Brown/DCT during the short production run of the 335is platform between 2011-2013.

I'm still trying to find out how many were produced just in its last year of production (2013 which is my model year) in my spec noted above.

I've searched everywhere (including a BMW stealership) to ID this info and I just can't locate it - do you have any thoughts how I can??

It's REALLY zippy (stock) and really handles incredibly well/stops incredibly well.

I know you love your 1 series E93,


Really enjoying the mods I'm doing and mods-to-be-soon.

Re your comment about driveline HP loss at the rear wheels, I did a semi-deep dive on this last week, and there's so many opinions. At this point I'm using the info I found (I believe from Motor Trend) stating the average line loss is 15%. There's so many variables regarding type of transmission, etc.

Does that seem like a relevant amount? Any thoughts?

Yeah 15% seems to be the average consensus of drivetrain loss. Only way for sure to know on your specific is to do a base line bone stock then revisit as you go. Plenty of factors fudge the 15% in either direction but that gets you the best guess without doing a baseline first.

BHP I look at when I use to work in the archery world. IBO (international bow hunters org.) And AMO (archery manufacturers org). IBO is as fast as a bow would shoot at a longer than average draw length bare string lightest arrow possible without damaging the bow 70lb draw weight. AMO is 2” shorter on the draw length for less power stroke 60lb draw weight with a hunting weight arrow and string accessories. What all that means is the practical average person will get somewhere in between to the lower speed side. But everyone who buys a bow concerned about speed is focused on IBO marketing. IBO/BHP. AMO/WHP all marketing.

Indeed!
Perhaps Wed?
Let me know where, time, etc.

your dawn dish soap gave me a chuckle. When bagpipe bags went synthetic and hide/synthetic blend the diluted dawn is the easiest way to get the pipe stocks into the collars on the bags rather than the old school tie in. Lookin good and making some great progress quick.

thank you piper,
my brother had a saying re those that possessed every conceivable professional grade tool to respond to every conceivable repair...."band-aid to open heart". car lift, tig welder, lathe, snap-on pneumatic tools, etc.

it seems that dawn has achieved this prestigious level. the clincher for me is select video of emergency response teams that are recovering small creatures from a beach where an oil slick has grotesquely altered the environment and its smallest of living things, and the teams are removing the oil and saving the lives of small birds, etc using dawn dish soap.

perhaps the international wildlife community can conceive an award and present it to dawn for its "band-aid to open heart" capabilities....

hoping yout beloved z ride "iz" awesome!
