    There are two kinds of larger turbo N54 enthusiasts. Those who are running the JB4. And those who will switch to the JB4 some day. If you're in the latter group we just haven't developed an enticing...

    Right, N55 is single bank. So this method would not work for cylinder specific boost leaks or fueling issues.

    Interesting, never considered that. Something to keep an eye on. At least we know what a torn seal looks like now. Huge bank to bank variance. We've had this one on and off 4-5 times. Jon @ BMS did...

    The biggest safety concern with a PI kit is one injector not spraying. With twin banks you'd see the trims in that bank pitch up as the DME attempted to add more fuel to the bank to get the average...

    Curious to see how these do! Definitely come along to a Famoso day. I think I'll take our MOTIV 135i out to the next one and take another crack at being the first N54 in the 140s. :)

    Present company included. Working with more tuning on the hybrid twins lately I've found lots of areas the JB4 mapping for them can be improved. So that will eventually be a win/win for everyone! :)

    It's like breaking the speed of sound. The probability of something bizarre breaking or happening reaches 100% as you approach 700whp. :) First our intake gasket issue. Now this bizarre misfire that...

    You guys still battling over spool? lol. If you want to overlay our E92 MT as tuned so far at 28psi, missing up top, 4th gear 3.08 rear, to your MT car then go for it. Here is a similar dimensional...

    Definitely dual nozzle with bungs spaced well apart 130-180 degrees. I'd start with a dual CM7 and work up from there. Likely will end up needing one of them to be a CM10.

    With meth and a proper safety system, that protects against tip in knock as well as meth flow reduction knock, I see no reason you can't safely make 600whp. Compared to pump only meth is a game...

    It's a high compression motor with cast pistons. The more you lower timing to avoid knock the higher EGT will go. It just doesn't sound like a good long term plan to me. I think something in the...

    You can probably make 500whp on 93 using hybrids but not sure why you'd want to. It would be a disaster waiting to happen IMHO.

    He's got a CM10 and CM7. It's just funny the first car I start to evaluate the safety on -- has an issue.

    So just got this log from a meth customer running the TFT chargepipe. This would trigger the safety when implemented. So we'll have to get to the bottom of it and start evaluating logs from more meth...

    Maybe! It spools about 1000rpm sooner so I'm thrilled with that. Once we fix the misfire and can do clean pulls at 30-32psi it should go right by that 700whp barrier. :)

    It's still down at PURE and I'm just helping sort it out remotely. Results are impressive so far but a few bugs on the car to fix before it can claim the dyno record. :)

    The need for bank to bank safety systems

    Hey guys,

    We've started tuning the E92 with modified twins and came across an interesting issue. A fairly large and unexplained fuel trim bank to bank variance. Note bank1 is shown under trims...

    Annoying it's not working right but at these power levels it's just a fact of life. OEM motors will eventually break one way or another. Focus on getting the built motor in!

    It's called a JB4. Juice Box was the original "Terry Tuner" 2008 adapted product. There are probably still a few guys still around here who ran one back then. :)
