405awhp in my 335xi

[jpsimon]

what's up guys? It's been a while since i posted last.... I thought some of you might be interested in the power i just made in the ole' 335xi.... (these highest numbers are on 104 octane and a race map. the 2nd highest numbers were when i was on 100 octane with NO race map).

405awhp / 407awtq. The only mods: PROcede V3.1, UR Catless Downpipes, AE Catless Exhaust, Dual Cone Intakes



and of course a pic of the car:

wow. awesome!

[italian a4 1032]

nice

[juju4uofa]

That must feel awesome. 325awtq @ 2,000rpm FTW!!!

Unless I can miraculously find a way to afford a 997 Carrera S a 335 will most likely be my next ride.

I feel you brother. I've been thinking the same thing. I would go for either the 335i or the xi but NY winters are'nt too conducive to rear wheel drive cars.

and the xi is awd... so what are ya saying lol

Here is basically your setup against a stage 3 s4. This guy had the same ecu, full exhaust (not positive on brand), hks ssq, dual intakes with some fancy looking piping. He was an auto...which is probably why he got pummeled. Non xi though.

He was running mid to low 12's, trapping about 114 iirc.

Sorry for the bad footage, I was in my A6 and I couldn't keep up. I was also the driver AND cameraman.

Nevertheless, nice car you got!

ah good ole' horrible night time footage and fuzzy race details :)

Maybe I don't know what I'm talking about.. but doesn't stage 3 include ko4's

[Das General]

Fuzzy race details? I don't know his exact numbers... he certainly ran very well at the track though. When we told him we had OE turbos with just an exhaust, tune and intercooler, he was licking his chops. He was a nice guy, but rather typical of a BMW, who had no idea what he was talking about and was bragging about how he was a forum moderator. He had a jazzy N54tech.com sticker on his window, so I searched around but couldn't track him down.

The footage is great too! JK. Bad footage or not, he had no chance. BTW that s4 he goes up against ran a 11.9 @ 123 that night (full trim/full exhaust/pump tune)

[jpsimon]

haha well no wonder he won... there aren't any (many?) 335's in the 11's yet. But you gotta appreciate how much power we can make with the simplest of bolt on mods. I don't even have a FMIC yet (RaceTec FMIC coming soon!!)

help me out here though. Stage 3 s4 = full exhaust, ko4's, etc?

blizzaks are going on my car soon, but next spring i'll hit the track to see what a higher horsepower XI can do. I'll have my FMIC far before then too.. so it'll be interesting for the community for sure. (i've never been to a 1/4 track, that kind of thing never interested me)

hahah yeah. it is a very well running stage 3 (10secs4 tune, if you will)

Stage 3 is a K04 turbo setup, tune, full exhaust and arguably FMIC.

I am impressed with the power of the that 135/335/535 series motor. Sure does make some power. I wonder if you guys will ever try to fit larger turbos under that hood. I know it is very tight under there.

You should take your car to a track and see how well she does.

There are a couple companies working on turbo upgrades right now. AMS just burst onto the scene and said they're gonna whip together a sick turbo upgrade for us!

I realize the turbos are small however IMO peak power is delieverd very close to the ideal rpm. A general rule of thumb is to have peak power 10% before redline. Assuming you were running to redline it appears it's at 6800 rpm. So, "ideally" you'd make peak power at 6,120 rpm, only slighlty higher than the current 5,750 rpm. I personally wouldn't want to go much larger with the turbos unless you can safely increase the rev limiter. I would imagine your cam driven high pressure fuel pump would be your limitation there.

BTW, what problems are people having with the pumps? Are they not large enough? Do they fail? Are they harming the camshafts and/or followers? I'm just curious.

It's certainly going to be interesting to see the progression tuners make with this engine.

An intersting fact I just discovered is the weights of all the cars with this engine. Everything listed below is with a manual transmission. I'm shocked how the 535i stacks up in the group!

335i 2dr - 3,571lbs
335i 4dr - 3,593lbs
335xi 2dr - 3,759lbs
335xi 4dr - 3,814lbs
335i 2dr convertible - 3,946lbs
535i - 3,660lbs

Fuel pumps on certain build dates are failing (on stock cars).

Whereabout are you in connecticut, and how much does it cost for a ticket to go on this ride?
