    • 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.

        That one sure made me raise an eyebrow. He might want to consider doing a search on BMW Motorsports here before acting like he knows something everyone else doesn't. Especially something so damn basic...

        Guys pleases ignore the 500whp comment from Shiv. Yiu certainly don't need to be making that much power to have this happen. It'll happen at just 15psi with RB turbos for me and it was happening for Big Tom at less than 500 as well as he was on stock turbos. Has nothing to do with POWA at 500 like he's so wrongfully construing

        If you toss a SMFW in the passenger seat I think your covered. Plus you save money on the install.

        One more thing to mention that came up a couple times, its got nothing to do with the "state" of the dual mass flywheel (i.e. wear) or state of the clutch. I replaced both with a brand new DMFW OEM and a new HPF clutch and it still happened right after break-in too and it still happens 10,000km later.

        My only question is why was there a pic of the front of the head if the solution was the dmfw? Just to get a rise out of everyone? Other than that, I look forward to some trap speeds from some of these cars!

        reading the thread over there now, its comical how many people are on his ballbag...

        an accomplishment for finding out what should of been found out before the kit was released 6 months late? So comical to me... Just proves no testing was done on an otherwise stock car, like most of his customers buying the kit would have.

        Look at T , he fixes the flatline issue, contacts cobb and shares the "fix" with the community and other tuners. I feel like Shiv would of glorified it in his own thread or two and than charged for the fix... I dont care if Procede made 50 more whp over any other tune , ill never run that in my car for the sake of how bad the customer relations is and how ass backwards things are done...

        Great, and we get no credit for forcing him to acknowledge it. Sheep.

        So how much does this SMFW add to the cost of the kit? Is this something that will be included in the ST kit moving forward since it is a necessary component for 6MT's?

        This isn't a single turbo only problem. If it does end up being the issue, the info will benefit everyone. Hell I needed to upgraded my clutch/flywheel on stock turbos. It is a necessary component for everyone looking to make any power.

        I don't understand why everyone is being so hostile. tmo335tt believes he found a fix for the misfiring issue. When I spoke to GeorgiaTech335Coupe at PBIR he said that they had been working on a solution for weeks, trying to figure out what was causing the misfire issues. Lets just hang back and let them test out their theory and see what happens. I hope it works out as I know they all must be really frustrated with their cars at this point. Can't wait to see what kind of numbers the single turbo cars can get once the bugs are worked out.

        By the way, I got an e-mail from the guys that set up the PBIR track rental (I'm sure you all did) that they are trying to set up another rental towards the end of January or early February, hoping for some better weather.

        Yes, I got the email. I'll try to make it down again.

        Good stuff. If the weather looks to be good, I'll head up again as well. Hope your car is at 100% by then.

        FWIW I didn't notice any RB turbo cars at the runway race who had 4->5th gear shifting problems. Only the issue of the trans sometimes unlocking anywhere from 140-160mph when fully loaded in 5th.
