    • Just how quick is a bolt on modded BMW 135i? Watch one race a stock C63 AMG coupe

      Now, this video is not the best quality as it is from an Iphone. That is OK though, it is still easy to see what happens as the 135i takes the C63 by about a car length. Definitely impressive considering this is a 6 speed manual 135i and that it also had a passenger. Remove that passenger and it will buy another car length. The C63 is stock and the 135i has a BMS JB4 (order one from our vendor Burger Tuning if you like to win races), downpipes, and a meth kit. Definitely a quick 135i on the street although a tune on that C63 will be put the advantage right back in its favor.

        There are some MPH's where it isn't best for you.

        When I would run my friend in his STI he liked to be in second but that was the end of first for me. If I went out of first, I would hit the limiter almost instantly. If I went out of second, I was just at slightly too low of an RPM.

        If we lowered the speed to both go out of first, the DCT shift time on the 1-2 would instantly give me a car and he hated that.

        So, you can pick speeds that will help or hurt you depending on the setup, etc.

        1st goes to 42mph. Too high rpm.

        42 mph and 30 is too high? why, because it smokes the tires probably, not because its a bad speed. thats your issue, not the cars

        Yes it would spin bad and hit the rev limiter right after.

        Not sure. But he had superlight wheels. Which he said.

        lol , my wheels were not superlight AT ALL... they are Advan RZ wheels with 235/40 and 265/35 tires... wheels weight 19lbs and tires weigh 26lbs each... if you want to get technicle you have conti DWS on instead of your factory run flats that prob save you more weight than my setup does... My setup weighs 2-4lbs each less than my stock wheel/tires did... (215&235) Rims are not the only thing you can save weight on.. GO on tire tire Conti's DW and DWS are actually the lightest performance oriented tires out there. I could of and thought about but chose to go with a nice size setup for road manners and stiff sidewall, went with conti DWS or I should of went with DW because I would of saved 19 lbs total on tires , and that would be rolling weight. This is stuff only we are crazy enough to pay attention to though, lol...

        If I was going for light weight I would of put 215 or 225 upfront and 245 in the rear and went with a light tire and wheel like LTW5's , K1's, or GTS-R... the Kuhmo Ecsta XS tires I have on there are actually way above average as far as weight is concerned, but I got all 4 for a crazy good deal so i said F it...

        this is the stuff that makes me shake my head... my look nice set of summer rims turns into superlight race wheels that stick like glue and shave .6 off a first gear pull... lmfao

        I had a set of kosei's with 215 up front and 245 nt555rs that I sold because I didnt want to have stupid looking wheels on my car to save a half - full car lenth... My radial setup is on stock z4 wheels that weigh MORE than my OEM wheels.. dumb, yes. But its what I could get at the time...

        chuck, we already know what to expect w/jon. a fender is buslengths if he loses (rare in itself) fender is trainlengths if he wins, 1mph is 10mph for what he can gain, ect..

        Lol I wish I could do a 30 roll! I'm spinning in 3rd now. Click here to enlarge

        I ran Jon with a 50 additive on map 3 but had fuel/timing issues and we were dead even to like 125. Terry told me today that map 3 50 additive isn't 18 psi. Bastard. Click here to enlarge anyway map 6 with proper additive and fuel/timing is dialed in now. See you guys Sunday. Bringing a FBO DCT 335is with me.

        PS here is the Map 3 curve that we throw an additive on. Also factor in that the JB4 is notorious for running less than target even on BT board.

        So 17.8 target is actually like 16.8 lol, tapering to 13-13.5.


        psi_curve[0] = 95 '1500
        psi_curve[1] = 100 '2000
        psi_curve[2] = 100 '2500
        psi_curve[3] = 110 '3000
        psi_curve[4] = 115 '3500
        psi_curve[5] = 120 '4000
        psi_curve[6] = 122 '4500
        psi_curve[7] = 128 '5000
        psi_curve[8] = 125 '5500
        psi_curve[9] = 110 '6000
        psi_curve[10] = 100 '6500
        psi_curve[11] = 90 '7000

        19lbs wheels are very light. Mine are 28lbs.

        The C63 has a pretty flat torque curve compared to a stock turbo N54. $#@! even with RBs torque falls flat up top pretty quickly. Well make 500 lb at 3000 and 350 at redline lol.
