dude i am pickin up my 335i tommorow morning!!!!!! montego, auto, paddle, cold weather, performance, sport and nav!!!!
i am stoked!

You're gonna love it, or maybe you already have it!! Looking forward to pics. I haven't even posted nay pics of mine yet and I have had it over a week. I need to get out and put some pics today

Gotta love those turbos. I have a 87GN with a TE63-1 Turbo from Precision Turbo. I remember having 4 people in my car, and pulling away from the 405HP ZR1, and when we came to the next intersection, he rolled down his window and said..what is a GRAND NATIONAL?? Im not too far from Duttweiler Performance...he got 1700HP out of his little Twin Turbo V6. Ran in the 7s at over 170MPH in the qtr. Then he ran in high 6 second qtr mile, at over 200 MPH when he put the engine in a pro stock chassis.

Here is a pic of my GN

1. We set the car's weight conservatively at 4,030 lbs. (I had all my work stuff in the trunk, ~ 6 gal. of gas, and both of us in the car).
2. I have an AT/Step w/ Paddle Shifters.
3. I turned off DSC, but left DTC on...just a quick press of the DTC button; didn't hold down the DTC button to turn everything off.
4. I launched in M1 and used my Paddle Shifters.
5. I launched without revving the engine at all; straight from a stand still and no left foot brake, right foot gas thing...just like a regular launch.
6. We couldn't accurately get a 0-60mph timed, but we did get a good reading for the 1/4 mi.

1/4 mi. in 12.44 sec. @ 122.8mph

By our estimates, we think we could've been able to do 0-60mph in ~ 4.1-4.4 sec. without a doubt! Maybe someone else w/ an Xede-equipped 335i can time a 0-60mph run w/ a G-Tech timer to see if this is accurate.

Below are the pictures (taken w/ my Treo 650) of the G-Tech timer's readings...

I'm sure the xede kit improved your 0-60 times and 1/4 mile times, but there's simply no way those time you got are even remotely accurate. I could imagine knocking off .3 to .5 seconds (max) off the stock 1/4 mile performance and adding another 5-7 mph to your trap speed.

I've seen real 1/4 mile timeslips for 335i w/ the Xede kit, and the best time I've seen thus far is 13.4 seconds w/ manual transmission.

Go to a real track and do 3-4 runs post a timeslip. That's the true test.

Curiously, did you do a g-tech run pre-upgrade? If so, how did they compare?

Dude, you're either totally confused or on drugs. Stock 335i's have done the 1/4 mi. in 13.4-13.6 over and over again. There's another guy on here who recently used another G-Tech timer on both his stock 335i and '06 M3 SMG...and he got almost identical times. Why don't you check out his thread? With the Xede and another 57WHP and 92 lb.-ft. wheel TQ, an Xede-equipped 335i is MUCH faster than stock and is running in the low-mid 12 sec. for 1/4 mi. and probably low-mid 4 sec. for 0-60mph. Just check back in the next few weeks, and you'll probably see more threads of Xede-equipped 335i's getting timed. Next time, try doing a "search" on the Forum.

Here, I'll even make it real easy for you this time...

Perhaps a little confused at most.

Hotrod182 results for a "stock" 335i:
13.455 @ 104.29 60Ft 2.110
0-60mph 4.889 seconds.

Xede kit: an additional ~50HP and takes off another .5 seconds (10HP increase=1mph increase... and .10 second decrease in the qtr mile). Keep in mind that this a "general" rule of thumb.

Xede modified 335i: 12.955 seconds @ 109.29 (best case scenario - using the calculations above).

Even Hotrod182 also said this: However, there is absolutely no way for a 335i to run over 120mph in the qtr with only a 50-60HP increase in power.

Look, I'm in no way knocking the 335i; I think it's a very nice and quick car. What I am knocking though is the G-tech results.

IMO, even hotrod182's results aren't 100% accurate (though probably close)...authentic time slips is the true test of performance; nothing like a truly measured drag strip w/ highly accurate time and speed monitors.

[Jay@ATP]

First of all, Im not trying to discredit anyone. (or the 335i, cuz I want one)

I have used both the older Gtech that was used here and a new one. The old Gtech is bad. Usually wrong. The new one is a lot better and gives more real world like results.

Just think bout it. Every 10HP usually gets you .10 sec and 1 MPH in the 1/4 mile. Theres no way the trap can go from 103-105 area to the 120+ area, its just impossible.

Having said that, and after seeing timeslips from stock 335i's and dynos from stock and xede 335i's, I believe with perfect conditions and driver, xede'd 335i's will run high 12s, maybe mid 12s with the exhaust and xede.

While I agree, 122 mph trap seems high to me also, you cant just say 10 hp equals .10, therefore he runs a 12.9x at 109. You have to consider the torque increase, which is going to impact straight line performance more than the HP will. Its crazy how people get hung up on the HP while the tq increase is huge with the Xede, and its in a very usable range. Reminds me of Lingenfelters approach, maximizing torque. Mid 12s should be achievable.

Aside from that, the 335i probably has more potential than a 13.4 in stock form. I have yet to hear of anyone launching aggressively, using drag radials, or even VHT with street tires. 13 flat is probably achievable without the Xede.

Of course, we will all have to wait for true 1/4 mile results.

Exactly what I was going to say...these newbies forgot that the Xede increased my Wheel TQ by 92 lb.-ft. TQ, which is approx 445 lb.-ft. TQ (to the crank)...this is probably what gets the Xede-equipped 335i to 60mph at least .5 sec. faster and the 1/4 mi. at least 1 sec. faster than a stock 335i. Yes, it added another 57WHP, but the added TQ is unreal!

Also, I'm in FL running on 93 octane and the newbies should know that FI engines love higher octane; in CA, you're limited to 91 octane, but in FL, we have 93 octane and less strict emissions.

Ok, I think we all agree that my trap speed was off by at least ~ 8 mph or so, but most also agree (even Shiv) that my 1/4 mi. time was probbaly accurate...and that was with an "idle launch;" no power braking or revving it to 2000rpm at all.

most any sports car using drag radials and VHT will improve its times...that's not the point however. using street tires (better yet...the stock tires it comes with) will give us apples to apples comparisons and the best chance at measuring a 335i's performance.

I highly doubt that a stock 335i can do 13 flat; again, if you use vht or drag radials, the car is no longer in stock trim. after all, you don't see Road & Track or Car & Driver using drag radials or VHT. They use cars in its "stock form" - that's the fairest assessment.

look, do us all a favor and go to the track and post a time slip. power brake / rev it up to 2K...whatever. just post a real time slip.

remember this though, when you make claims that are in proximity to Corvette Z06 or 911 twin-turbo performance numbers you better be prepared to prove yourself w/ trustworthy metrics instead of using the highly inaccurate G-tech (the older version which is the one you're using).

fyi - there are approx. 20+ Xede-equipped 335i's on the road today in FL, CA, TX, and Canada. I am not the only one. I've asked all these other ppl to duplicate my tests AND/OR go to the track to get "official" times. So, before you get your panties all in a bunch, just know that "we're working on it."

However, my brother who has a majorly modded '91 Dodge Stealth Twin Turbo (that makes ~450+HP/500+TQ) and an '05 Lotus Elise, also agrees that my Xede-equipped car is as fast if not faster than what his G-Tech timer said (at least time-wise, maybe not trap speed). He's verified the accuracy of his G-Tech timer at the track with one of his cars.

In the meantime, you may want to think twice about challenging a 335i...he might just be Xede-equipped!

btw - I believe the 911 Turbo and 'Vette Z06 are sub-4.0 sec. 0-60mph / sub 12.0 sec 1/4 mi. cars, and I've NEVER said my Xede-equipped 335i was as fast or faster than either of those 2 sports cars.

Umm, when drag racing your usually at the top of the power band, which is where HP comes more into play, not TQ.

Like Maynardc says, go to a track, show us a time slip. That what matters.

Also, I will give someone 20$ paypal if they post up a timeslip and video of them driving their Xede & exhaust equip'd 335i (coupe or sedan, MT6 or AT) to a time lower then 12.4. Track must be a NHRA certified track.

FYI, I plan on using Vishnu mod path when I get my 335i. I am not trying to discredit vishnu, shiv, or the 335i in anyway.

Well, in drag racing, you are also accelerating from a dead stop, where torque is going to make a bigger impact. This isn't some 40mph roll on honk your horn racing.

Over the course of a quarter mile, how much time do you spend at peak hp rpm? Now how much time do you spend in the rpm range of peak torque. Considering peak tq is from 1300-5000, the answer is obvious.

Maynard states he has

I've seen real 1/4 mile timeslips for 335i w/ the Xede kit, and the best time I've seen thus far is 13.4 seconds w/ manual transmission.

. I'd pay 20 bucks to see those timeslips.

Here's timeslip of a 335i auto running less than 13.4 in quarter mile.

http://www.e90post.com/forums/showth...highlight=13.4

[sflgator]

I really think these guys are forgetting that the 335i makes Max TQ all the way down from 1,500rpm - 6,000rpm (w/ Xede), and I bet that neither one have actually driven a 335i yet, let alone an Xede-equipped 335i. Only then would they begin to understand just how fast this FI car is; and it's quite obvious that it's not just "butt dyno" faster, but so significantly faster with the Xede that it's not even funny...it's like "OMFG...hold on" faster!

If a stock 335i does 0-60mph in 4.8 sec. (which is what even Edmunds.com and BusinessWeek.com got when they tested a stock 335i -- and they don't do power launches like the car mags do) and the 1/4 mi. in 13.3-13.4 sec., then an Xede-equipped 335i with an additional 50+WHP/80+RWTQ absolutely spanks a stock 335i and current E46 M3 with much faster 0-60mph and 1/4 mi. times...almost definitely knocking off 0.5 sec. for 0-60mph and at least 1 sec. in the 1/4 mi.!

fyi - from Shiv in one of his recent posts this evening (from another thread)...

"Our gains are not only from mildly raising boost but also having full boost attainable at lower throttle angles and engine speeds. In stock from, the car would hit 7psi by 3000rpm and gradually creep up to 9-10psi by 5500rpm. Now it his 11-12psi by 2000rpm and holds it until 6000rpm, above which it slowly tapers down to 10psi. It also hits 90% of this boost level at 50-60% throttle. Whereas before, you would need to go full throttle if you wanted to see anything close to full boost. We also run the car substantially richer under boost which keeps EGTs in check which, in turns, keeps the turbos happy. We also run more ignition timing under low and moderate load which further reduced EGTs. Not only did BMW make one heck of an engine, they also left a lot of doors for us to open ."

Well put. Torque is all too often ignored. This engine has a great torque curve stock... and even better with the Xede.

In addition, I also think these newbies are also getting a bit "thrown" b/c I only have the Xede-only kit (Stage 0) with stock exhaust. However, even Shiv was surprised when he began installing and tuning the Xede Stage 0 (Xede-only) on 335's running on 93 or 94 octane gas. He found very similar results with the Xede Stage 0 running on 93/94 octane gas as he found on 335i's with the the Xede Stage 1 (I think Shiv has only done 2 of those cars so far -- his own 335i Coupe and IMSAMBEEN's 335i Coupe) running on 91 octange gas in CA. Apparently, the increase in octane really gets the car breathing and increases the HP/TQ (especially TQ); actually, the 93/94 octane 335i's w/ just the Xede-only (stock exhaust) have made much higher TQ gains than the 91 octane 335i's w/ Xede+exhaust (Stage 1).

Here's the thread to back this up...

http://www.e90post.com/forums/showthread.php?t=38595

So, this is important to understand in all of this --- the 335i w/ Xede Stage 0 running on 93/94 octane gas makes approx. the same HP, but even more TQ as the 335i w/ Xede Stage 1 running on 91 octane gas. Now, imagine when some 335i's running on 93/94 octane gas get the Xede Stage 1 with the Xede + exhaust setup...
