Those are quick times IMO. Now the question is how reliable are the cars after? BMW's and Benz seem like DD cars IMO
I wouldn't mind DD'ing a newer 335xi sedan (Iowa winters: Snow = BAD!). My question is the BMW reliability after modding. I've been around American cars to know. Can't say the same about imports

V8EATR

well the 335i's have typical bmw wiring issues and more than a couple motors have let go with people trying to push 20+ psi on the stock turbos and the turbos let go. i guess they seem to be ok unless you really try to push the stock turbos.

How much boost would a JB3 tune be pushing? Or better yet, the new Cobb Accessport tune that one could take out so one could attempt to keep their warranty?

TT Sedan

Wiring issues? What wiring issues? And the problems I've read about is failed turbochargers not failed engines. And these failures are from people hacking up their "chip" to make it run more boost without the fail safes in place.

But yes about 18-19 psi is about the upper range limit on these turbos, and u better be running meth or race gas or both. 18-19 psi and race gas is good for about 450 rwhp.

the c63 seem to have no problems really that are drivetrain related, a tune pretty much just puts it a little above the e63 (HP wise) its the same motor just detuned
doesnt dinan make a tune that keeps the warranty

TT Sedan

BmW can still void your warranty with Dinan Tune

TT Sedan

However much u want it to push. Typically people choose between 13-17 depending on mods.

Gotcha. Just testing the waters. It'll be several years (after college and whenever my DD dies) that I'll buy - just seeing what guys generally do.

V8EATR

My buddy works as a bmw tech and he has seen the turbos come apart and take out the motor. Im sure foul play could have something to do with it.

These new tunes with CAN access are fun. Everything is right at your fingertips.

For example my tune (beta testing) currently has 7 different maps.

Map 0: Stock bypass. This is the only map you may use a BT cable with.
Map 1: 13psi (suggested for most stock applications)
Map 2: 14.5psi (suggested for bolt on mods with 93 octane.
Map 3: Progressive meth (see guide to enable)
Map 4: Stock map w/ CAN active. Soon to be our economy map.
Map 5: (2/1 and later only) alpha autotuning map. Boost ranges between 12-16psi based on historic knock sensor feedback.
Map 6: Custom map. Active but be careful with it.
Map 7: 16.5psi. A light weight race map.

How do u access the maps?

You press the volume down and channel down button on the steering wheel at the same time.

Doing this puts u in control of the speedometer needle and RPM needle. U move the speedometer needle with the volume + and - button and move the rpm needle with the channel + and - button .

Having the speedometer needle on 0 allows u to change maps with the + and - channel buttons. This will move the rpm needle to the map of ur choice.

It's really a lot easier than I make it sound lol.

Here is our cheat sheet below

My tune also hijacks my gauges, for example I'm using my fuel gauge as a boost gauge.

Empty = 0 psi
1/4 = 5 psi
1/2 = 10 psi
3/4 = 15 psi
Full Tank =20 psi

Seriously? That has to be one of the dumbest things I've read recently.

Beans

From what i've seen from the N54 (x35i engine) it's decent if you don't push things too far.

As TT sedan can tell you, they have some fuel system issues. Carbon buildup is also a problem, high oil temps from road racing or even hot lapping at the dragstrip are also a problem.

Anything you do to increase flow for a turbo car increases the turbine speed. If the flow of the system increases, the turbine speed required to maintain the same boost level increases. Full bolt on cars running aggressive tunes for long periods of time can certainly kill the stock turbos. They are tiny turbos built for quick response and low pressure ratios, not to make big power. Keep the modding reasonable and it seems they are ok.

The benz is hugely detuned from the factory to prevent people from cross shopping with the AMG E-class. A tune is good for huge power with no compromise in reliability because the hardware is built for it.

TT Sedan

The c63 is a beast no doubt, but nodding it can get expensive fast. A tune is 3-4k, headers are 2-3k, exhaust is at least 2k.

The next big thing for the 335i is to get it ported and polished. This is said to increase HP by 40 on a stock car, and by 100 on a car running high boost. Cost is bout the same as a top of line tune for c63.

600whp shouldn't be too far away, but we do need more fuel.

Way to make yourself look intelligent

I guess those guys running 7s or lower 105+mm turbos with huge boost #s should just run 93, since only pussies use race gas

That's what all the DI guys seem to be saying. SS/TC's, MS3s, and the 135/335 guys run into a barrier with the fueling.

That's the way I roll.....$3-$4 gas is bad enough....If you want you can volunteer to pay $8-$10 for per gal for pump as race gas is and maybe I can get pump for me a little cheaper. Not race gas fan.....and not a fan of people running race gas at the track to get a # and then saying how fast their **** is and then not even knowing what it runs on pump and claiming it to be a street car....read my lips.... RACE GAS=RACE CAR....I have a street car.
And as for you WSsick...far more intelligent than you with a screen name like that and a Z28 in your sig....

TT Sedan

So you run dr's on the street? Pretty stupid

And Europe pays $7-8 per gallon for 91 octane. I tell myself this when I pay $7-8 per gallon of 100 octane lol.

But ya, with our shitty 91 octane gas in CA, I do frequently blend for 94 octane which comes out to about $4.75 a gallon.

Yep, never heard of wiring issues being a prevelant problem. Fuel pump yes, turbo's and wastegate problems yes, no failed engines/wiring issues though.
Your warranty isn't voided, but it is flagged as a Dinan warranty in the bmw system. The dealer will still honor the warrenty although I can't say what would happen if you take the car to a non dinan bmw dealer.
You should remove your tune before ever servicing the car. The AP is easiest, but having a piggyback like the JB3 will only take about 15 minutes to remove. As for tune, you can change some perameters with a jb3 and now jb4, but the real interesting thing is when Cobb releases thier pro tuner software. Should open up tuning similar to HPTuners for the lsx cars.
Head work is the next big thing but damn it's something like $2500-$3000. Only a matter of time before other rebutable options are out there for port/polishing the head on these cars.
I agree to an extent. I'll run 93 pump on my setup, but I wouldn't call a person running racegas something less just because that is his choice to run that gas.
I'd probably mix too if I didn't have access easily to 93 octane.

Well TT I guess you'll be calling alot of people on here stupid.....Besides if you noticed I have my 18"rim times listed too...although I've made some changes since then and I'm sure those times will be quicker too....the car was hitting the rev limiter berfore the traps on that run.

People who want to win races run race gas. Do you even know the benefits of it? Obivoiusly not, or maybe you got beat by a Honda on race gas and are still bitching about it. Race gas is for those who don't mind spending extra money to win a race. In street cars, it's not like they run it all the time. Drive around on pump...race comes around, throw in the 110+ and have at it. Nothing wrong with trying to best your chances at winning.

As for my name, I made it when I was deadset on getting a WS6...then I changed my mind, but oh well. If you honestly think a person's intellect can be figured by a username, than I gave you wayyy too much credit in thinking you had more than 4 braincells.

Maybe I should judge your mental capacity on how poor your sentence structure is?? A 10 year old could write better than you. Better judge than a username for sure...
