Looking to take my n55 FBO minus exhaust down to the 1/4 mile and was just wondering the best way to launch it?

[LMB335IS]

Good luck. I have a 335is/DCT. My launch control is set at 5k rpm so it's useless with 460 whp plus I don't want to break anything trying. I can flash the 135is TCU file to my car for a 3500rpm launch but haven't tried it yet. A couple weeks ago I went to the strip for the first time ever and did a best of 11.86@118.32, pretty damn good for a virgin! No water box since you can't brake boost to heat up the tires. I just rolled on the throttle at the 2nd or 3rd yellow and hoped for the best. Track hooked well as I was just on regular street tires. My 60 ft were all 2.1-2.3 so the car really went hard after that.

At LMB335IS : what tires are you running? Make, model and size. Those times are impressive. Good job!

Thanks! Yokohama Advan Neova AD08 275/30-19. Ran them with 35/36 psi. 25-30 psi might had made a bigger difference.

Those are great tires. I remember the ADO7 was standard time on the Lotus. When I was replacing my Michelin PSS I wanted to get them but they were pricey. Basically, I could have bought 6 new Michelin PPS for the money. I opted for Hankook RS-3 and been happy with them.

Again, congrats on the awesome numbers at the track!

I got lucky. Found them in the for sale section. Brand new 235/35-19s and 275/30-19s for $800.

WOW, I would have bought 4 rears at that price.

Yup, really only 2 ways to launch a DCT Car. 1st is just mash the gas when the last yellow light lights up. 2nd is the car's stock LC. Our 335is LC is 5k RPMs as stated above. I tried it once and blew the tires off on street tires. I have MT ET streets for the track now. BuraQ has given me a couple pointers on how to use the LC and not launch at 5k. I'm going to try it this weekend on the DR. Hopefully I don't break anything LOL.

great time for a crappy 60 ft.

What was your 1/8mi ET and trap on that 11.8 run? That's an insanely fast 1/4mi ET with that crappy 60' LOL.

It was 7.80@94.4. Car's pretty fast, driver mod needed, although that was the first time I've been on a drag strip. Lol

Yup, that's a nice 1/8mi time and trap. I'd be happy to break into the 7s LOL. All of my parts for FBO and meth should be here soon and I already have inlets in the garage so maybe I'll get there soon.

Shouldn't be a problem at all. I have inlets and outlets waiting to go in too, just gotta psych myself up to tackle it. Do you run E85 or is not available?

I live in the land of ethanol. Almost every gas station around has ethanol. I run e30 right now. Eventually I'll go to a fuel it stage 2 and e50ish.

What mods do you have on your IS?

Just pretty much standard bolt ons. Afe stage 2 si intake, VRSF dp's and IC, ER CP and Forge DV's, 3.5 bar TMAP, MHD custom tune by BuraQ, Stage 1 Fuel it, stock exhaust and I run E60ish. I run a step colder NGK plugs. I do run a pretty aggressive tune.

I also have a full M3/BMW Perf suspension/Powerflex rear subframe bushings and a lock down kit which may help a little on launch, who knows. Lots of other stuff but this is most of the go fast items.

Do I need the Forge DV's? Also is stage 1 fuel it for meth injection I assume? What's 3.5 bar TMAP?

You don't need the Forge DV's. You can run the stockers until they give up. I just like them from back in my VW days. Stage 1 is a extra inline fuel pump that works together with the factory LPFP to increase the flow so you can run high ethanol (E85) content. And the 3.5 TMAP is the sensor in your charge pipe. It allows me to run a little more boost than normal.

Do you still have that 2011 335ix or did you get a N54 car?

Thanks for the info!

Yeah, I still have the N55

Ok, just checking because none of this really applies to N55's. Looking to get a N54?

[bigdnno98]

Well ran 8.4@87 tonight in the 1/8mi. I tried a 5k LC launch on the DR and the Tranny certainly didn't like it LOL. Probably be a trans rebuild and Dodson clutch packs in my future. It didn't slip but was more like a bang or something. No trans malfunction code but it didn't few good for sure. lol. Ran .1 faster than last week. IATs were awful. This stock IC really sucks.

You're a braver man than I. That's a sure fire way to grenade your driveshaft. Do you have the boost turned down in 1st and 2nd gear with your JB4?
