    Terry, I had pretty small filters on the Proto stage 3 kit, at one point I was sure they were restrictive and went through all the work of getting them out of there and putting screens on them just to make sure. Did dyno runs right before I took them off and after the screens were on, no difference at all I was pretty surprised, the filter is probably ok.

    When we first started with the single turbo project we thought we wanted 700whp in the e92. So the 6466 was the natural choice. And it is a great turbo. But after we got it running we found the car is more fun to drive at 600rw which is what we're running around with now. It's about the limit of traction, fueling is easier, and overall for how we use the car it's enough power. Since we're happy with the lower power levels we're thinking why not go get the low end back with a smaller turbo. And since I have both cars in the driveway I can really get a good back to back comparison between the 6466 kit and their new 5862 TS top mount. It's really no comparison for me. The 5862 kit is A LOT more fun. And if on race day we can push it to the limit like we've done with OEM turbos in the past and squeeze it up to 650rw that would just be icing on the cake. But even at 600rw it's fast enough.

    Where the 6466 would really shine though is in those 1/2 mile races. The real hot ticket might be their 6466 in a twin scroll format. The TS is a real game changer IMHO. But I'll have to weight the costs vs. benefits there considering the 135i is going to be the main race car and the E92 is more of a nice daily driver type car. In any event if someone wants to buy a top notch bolt in single turbo kit TODAY then FFTEC is really the only choice. It's not the cheapest option but it's really beautiful stuff and very well supported.
    Yeah, I hear ya I was originally looking at 6466 or 6766 and comparables, just don't see that size turbo on this car yet...5862 looks pretty good so far, but don't be mad when I spool just as fast and make another 100whp on my FP HTA Click here to enlarge haha

    Yeah, I hear ya on FFtec too, I know I'll love my car when it's done, but not many can go this long without their car.

But with todays fueling hardware it's just not possible with the air/fuel ratios and steady fuel pressure I'd need to be comfortable with it. Maybe with tomorrows hardware it can be done.
    I just wanted to quote this so more people can read it and better understand the fuels and how the limitations work/why. Great post here. It's such a misunderstanding for people.

    @Terry@BMS the screen on the turbo inlet is a bad plan. We've found them to be extremely restrictive. Perhaps due in part to the way they chop up the air stream. Kills flow and creats mini vortices right in front of the compressor wheel

    Totally agree with this. No one should ever run a screen on a turbocharger for any period of time, forget the vortices, thats the least of your worries, you are letting dirt, rocks, you name it that can get through the screen directly into the compressor, if you fear you are running a restrictive filter you can remove it and run either a very open mesh screen or no filter at all on the dyno and see if anything changes, but running any sort of screen on the street is asking for very short lives of your expensive turbochargers. The only reason people run them is because of bad turbo placement where you can't get a proper filter in place. Our stage 3 filters were sized accordingly for what we thought it would need, but once we ran into a few problems we were just checking everything to insure we could check those off the list. The filters were not the problem and the screens were removed after a few dyno pulls and the filters reinstalled. Bottom line, never run screens people, they are bad news in more ways than one.

    I don't necessarily mean the numbers exactly he stated, just the general mindset. On most cars, the only way to run high E85 concentrations without meth is by leaning the AFR out and a lot of people don't really understand how much of an effect that can have on fuel volume.

    Just for kicks, E85 max power rich is a lambda of 0.71 (vs gasoline of 0.85), and E85's max power lean is 0.87 (vs gasoline of 0.9). Running high concentrations of E85 at 13.3 gasoline AFR (lambda of around 0.91) is actually leaving good power on the table, not to mention boatloads of potential cooling. Looking forward to see what Tony has up his sleeve to address this once and for all.

    Because of lag, you also make less torque down low where the HPFP is known to struggle.

    Is there a reason you're not winding it out to 7200? The way the torque-band is playing, it looks like you still have more in it just from bumping the rpms up.

    Yeah, I've never liked or used screens. I either run a filter or just no filter at all. With a dremel and rerouting the oil cooler lines there is plenty of room for a larger filter if I ever need it. As long as I keep this one clean it probably doesn't matter much at this point. The trans is a more pressing issue.

    @Terry@BMS the dyno run in the vid, open downpipe or closed?
    is it better for spool with open downpipe?
    how is the sound with the open downpipe? extremely load or reasonable

    Are you looking to do LVL10s torque converter swap? Or a full build of it?

    I know I speak for plenty of people when I say I anxiously await your results from the trans build. This car will absolutely destroy at the strip once you get the steptronic to hold.

    I thought level 10 was proven to not really be a legit upgrade? A couple of people have used them and yet we are still searching for a legit trans rebuild option.

    I know...it's weird I feel a few people have as well. The most well-documented one was lostmarine's and it was never tested fully. Who knows who has the car now, probably someone with just a JB or something and has no idea what type of trans work is done lol. I know there was another guy that did one and failed pretty quickly, but I also heard he did nothing except the clutch pack and didn't break it in and just let it rip at the trick right away; so who knows.

    I just think it's weird people still bring them up bc if it worked everyone would have it

    I've said it many times, until someone can reprogram the trans, your only half way there with a clutch pack upgrade

    Had my level 10 with Vargas stage 2 batch 1 running between a 65-75 additive on map 3 for almost a year now and have had zero issues. I know its not the power level terry is running but I've beaten on it daily and its fine with no hint of a issue. I did converter, va lvebody, and their rebuild kit.I had it on stock turbo for a while before I installed the vargas t urbos and I've been happy. It was over 7k with my local trans. shop doing install but I've been happy.
