    • Trouble in paradise? Vishnu/FFtec N54 335ii Single Turbo kits experiencing issues as a BimmerBoost member runs 12.5@121 with misfires and having to short shift

      BimmerBoost would like to thank member GeorgiaTech335Coupe for his openness and honesty regarding his Vishnu/FFTEC single turbo setup. Recently, this member took his single turbo upgraded 6-speed manual 335i to the PBIR (Palm Beach International Raceway) dragstrip in Florida to do some testing. His best run was a 12.50@121.6 alongside a 12.8@117. Yes, these times are quite a ways away from the 10.8@131 glory pass from Vishnu demonstrating the kits capability.


      This is in no way the fault of GeorgiaTech335Coupe who experienced misfires on his car and had to short shift at 6300 rpm in order to avoid them. Now, Vishnu has basically portrayed this kit as perfect and ready for sale with nobody having any issues. The reason BimmerBoost is bringing this issue to the attention of the community is for potential buyers to understand what they are getting into.


      There is absolutely nothing wrong with having issues when modifying a car to this level and BimmerBoost is confident Vishnu will resolve them. There is something wrong with pretending nothing is wrong. A few cars with the single turbo kits have gone up for sale and apparently a total of three people, that are willing to open their mouths, are having misfire issues with these kits.

      These issues will no doubt get resolved but potential buyers and current customers needs to be aware of the process, effort, and that progress is being made. Pretending nothing is wrong and collecting money simply is the wrong way to go about this and once again (it's becoming a trend) BimmerBoost is the only site bringing these issues to the attention of the community.

      For the record, a member by the name of @tmo335tt says he has a hardware solution for the misfires that he will likely share with Vishnu (hopefully not for free). Interesting that it isn't Vishnu but the community solving this.

      Thanks again to @GeorgiaTech335Coupe for sharing his details, good or bad, as we all learn thanks to honesty and openness. There is more to tuning than just collecting money.

        Still waiting on the correct parts from Spec. They shipped yesterday, would think they'd be here by Monday if the holiday doesn't interfere.

        I already got the parts in today. Unfortunately, the shop is booked today so will have to wait until Monday for the install.

        UPDATE (12/26/12): Confirmed the solution. Georgiatech335i just replaced his stock dual-mass flywheel with a single-mass flywheel and the high RPM misfire is gone Click here to enlarge

        see other thread. I'll try this weekend, but I'm sure it won't be easy. This clutch is 100% different than the ACT, so I'm still learning. I'm still waiting for my suspension stuff too. I will def be trying though!

        I don't even care if it runs 13's, I want to see 125mph+ trap speeds.

        That's the expectations I'm going in with. Although 125 mph won't make me happy. 128 mph will be satisfactory. 130+ will be desired/expected.
