I'm taking my 335i to the track for the first time tomorrow....I've ran a bunch of cars down the dragstrip over the years, but they were dedicated drag cars with slicks and 4-link suspensions that were designed to transfer weight to the rear and hook up. These 335i's aren't set up for drag racing........so they just spin the the tires.

Any tips or advice for getting a good 60ft time out of a 335i? I'm running 18" Firehawk Indy 500's in the rear.....and although they grip ok, I can still spin them like crazy in 1st and 2nd gear. I'm making around 575hp with my current setup.

I've heard launching in 2nd gear is best? Anyone messed around with the MHD boost by gear settings??

Any tips or suggestions for getting a good 60ft time?? Thanks!!👍

Apparently nobody here has ever taken their car to the track?

Let us know how it goes! Is your hp rating a guestimate?

Sort of...based on known weight of the car, and the trap speed on a 1/4 mile run according to my draggy. According to all the calculators I've found online...you need around 600hp to get a trap speed of 127mph with a 3800lb car. And with RB TWO turbos at 25psi on E40...I think 575 is a pretty solid estimate (give or take).

2nd gear 1500-2000rpm launch depending on grip off the line. What size are your indy500s? I ran 255 indy 500 at the strip and would slip at arpund 3k rpm on fbo e40 ots tune. Traction will be your biggest problem with getting a good 60ft.

I got 2.04s on the street with 275 continental extreme contact sport.
Break boosting to 2.1k rpm in 1st gear, launching the car at 60ish% throttle and shifting at 4.5k rpm into 2nd, then going to redline. Also, had sutphin trans tune but with what ive seen on youtube, drag mode will get you the same result but with added stress on the trans.
Probably could get better but if I cared I rather have drag wheels at that point cause it's pointless without them on this platform.

Well......I was pleasantly surprised....

1st pass of the night....I knocked out a 10.90 @ 128mph...with a 1.84 60ft time. I was shocked!!

I made four more passes, and all were slower. I either left to hard and blew the tires off....or got a little lose mid track and had to pedal the throttle a little bit.

Man...this car scoots! Not bad for a pair of "smaller" RB 2 turbos, and an E40 tune...leaving in 2ns gear on street tires. I bet with a set of slicks where I could actually leave hard I would be down in the 10.6's.

I tried launching harder on one run, and knocked out a 1.74 60ft time....but smoked the tires as soon as the boost came one. 1.74 60ft on street tires (Firestone Firehawk Indy 500's) is pretty impressive!

Do you have lsd?
Boost by gear is good too.

Nope....that was with a factory e-diff. People always say the e-diff on these cars suck...but if I can pull a 1.74-1.80 60ft with one on street tires...they can't be all bad ,😁

That's incredible for the level of investment and about a second faster 1/4 mile time than the BMS or Arm 500hp set-up!

Yeah....for no port injection, no slicks or drag radials, the factory e-diff, no fancy fueling setup...I was shocked. I guess it just goes to show how the right combo of parts and a good tune can make the magic happen.

I think with the RB two being a little smaller (15t I think)....it really helped that they build boost so fast. I think the larger 17t and 19t turbos have just enough extra lag in them that it can kill your 1/4 et....even if they do make big power on the top end.

For a basic FBO setup with nothing fancy......I'm pretty happy knocking out 10 second passes on street tires 😁

Without a doubt you're faster than the vast majority of the rest of us have been and will ever be. Have you owned anything faster?

Back 15+ years ago I used to race a 1971 Camaro that was a dedicated drag car....had to trailer it to the track. It ran low 11's with slicks on it.......this 335 is faster...on street tires. Crazy how much power these 6 cylinder N54's can make!

[feuer]

Very good results! No doubt! Indy 500 are only 340tw. Softer compound will help. I run 120tw, Bridgestone Potenza RE71 on the ST n54 and Falken Azensis RT660 on the TT n54. Neither spins the tires. Need alignment to help with rolling resistance and narrow tires on the front. Noticeable difference on my car from 225/40 to 255/35 on the front when accelerating. If you go with different tires you will be able to shave of some time. Parts of a second. For more than a second you need slicks and more power. Good job!

[Cloverdale]

We owe our N54 great fortune to the forged engine internals (and the reasonably priced pre owned 335 market which seems relatively under valued when considering their potential and what M3's for example and so much more from various mfg's seem to sell for). I so enjoy my 07 auto that I added a second one (a manual). Not sure who was first to market with tuning and performance parts availability but that too is incredible value (an E85 conversion kit for my Challenger is more than double the price of my JB4). Don't think there's a better choice for performance potential in a very nice car for the price (but I'm preaching to the converted)!

Before I picked up my 07' 335i a few years ago I was trying to figure out what car would be the best bang for the buck as far as power per dollar goes. Everyone loves the LS motors...so GTO's, Camaros, and Corvettes are the favorite pick of a lot of people.

Honest, for the amount of money I have invested in this car.....I don't think I could have been running 10's in the 1/4 with any of those LS powered cars......an N54 powered 335i is hard to beat as far as dollar per HP goes. I picked up my car for $3500, and I probably have $3k in mods put into it (suspension, bolt-ons, etc)....and it's running in the 10's. I don't know what other car you could do that with. Hell.....an old early 90's fox body mustang will cost you $8-$10k.....and that's for a car with 250hp.....and it would take a whole different motor to make 600hp with it.

N54's are pretty amazing when you thing about how little it costs to make big power with them.....on only 6 cylinders!!

That price is unheard of even for a salvage / rebuild title even several years ago?

[Serf27]

Same reason I picked up a 335i.
I had just got a g37.
Nice car and power at 280ish. Seemed like the most power for the price.
Rode in a friends stock 335. Was told the mods weren’t too expensive and it could be even faster.

It was probably a weeks time or less that I got my 335 and ditched the g37.

It was pretty much a once in a lifetime deal. Some kid was selling it in another state a few hours from me, .had it listed for $6500. Said it wasn't running right, and he thought the "motor was blown". After going back and forth with him for a few days I told him I would show up with a trailer....no questions asked, and give him $3500 for the car. The kids parents already bought him a brand new truck...so he didn't really care how much he got for the 335i.

He accepted the $3500 offer. Turned out that it just needed a new battery, water pump, thermostat, and had a boost leak at one of the intercooler connections.....that's all it needed.

Does your home track not enforce regulations? Or did they kick you out? My track is pretty strict. You run a 11.4 without a cage and they'll warn you once. Do it again and you're done.

Just wondering if when your car does a 1 tire burnout like mine does when I load on too much power. I have been heavily considering an LSD but of course they don't come cheap.

My car doesn't do a 1 tire burnout.....it spins both tires. The factory e-diff works great...good enough to knock out a 1.8 60ft on street tires.

Has someone coded off your e-diff??
