Similar hybrids turbos are way more priced then franken.... if this time problems will be fixed this turbo will be the next Booming in the mkv platform lets see the first customers review and then we will all decide
Well here it is, albeit a few weeks too late..."first" (am I??) mixed flow F23T review...will update as things develop!!
Damn!!! That's impressive! Was that on a stock motor? And also curious if you guys have worked out the quirky wastegates, I heard of some issues with crazy boost spikes and the need to run a manual or electronic boost controller.
The wastegates weren't quirky, the cracking pressure was simply set higher in the beginning of the product's lifecycle...not an issue now, they're all set to 9psi (could be 8psi, I'll defer to Doug on that one)
This.
I like the product you guys have, but I won't buy a Frankenturbo until the hardware is consistent enough that a company writes a file that doesn't need to be tuned. I want to bolt up the hardware, flash the ECU, and drive away.
Then you have no reason to wait, the time is now. The "inconsistencies" were related to my previous statement about the experimenting with wastegate cracking pressure. There is no inconsistency now, it's 9psi on all new F23T's. I had my shop foreman install mine, I'm running Uni's K04 file (all supporting mods including S3 injectors etc.) and simply "drove off" with a car that ran as smooth as it was stock, stage 2+ and K04 (had a BW K04-064 prior to my F23T).
Yeah might consider this turbo when a tuning company like apr uni revo Dm start writing files for it
Again, the time is now...Unitronics makes a file for the F23T guys...visit their website, click the FAQ's...they lay it all out there for you. I spoke with them and they simply don't advertise the file (why would they, they promote and sell their own K04 hardware/software). It may not tweak every last ounce of juice out of the new mixed flow F23T but it is turbo specific and creates more boost and power than running on their K04 file. I will be purchasing the Uni Connect cable and upgrading my tune in April...will def log and update so we can see the before logs (see below) and after...I'm excited because the car already pulls MUCH harder than my K04 ever did.
So I saw those posts and felt obligated to reply so people can start wrapping their heads around the fact that Doug and Frankenturbo have an awesome product that is certainly worth consideration if you're upgrading your stock turbo, I'd say even if you're looking for a worthwhile upgrade from K04. Doug, I apologize I haven't posted sooner (installed March 2nd) but I've been crazy busy with work, the car and getting the nursery and everything else ready for my baby boy coming in a couple months (already rocking the full Recaro car seat stroller setup lmao!!).
I'm Josh, live in NH and work for an Audi dealership here. I've been into driving and modding VW/Audi's since 2000 when I had a stroked, balanced and blueprinted 12v VR6 Jetta with a lightened flywheel and GIAC software (God I miss that all-motor car, should never have let her go even tho she was nowhere near as fast as my GTI). I had a K04-064 go bad on me, wasn't the turbo's fault, PCV froze on a long winter drive and starved my previous engine and, at the time, brand new K04 of oil. The shaft play when we took it out was staggering and she pulled strong all the way to the bitter, smoky end lol!
My shop foreman installed my F23T with the MBC (rec'd by Doug) on March 2nd. He was actually quite impressed with the overall quality and fitment of the F23T, which is saying something because he isn't in love with the mod scene being a dealer technician (almost thought he would say no to installing haha). My first drive in the car we set the MBC all the way conservative and I was only boosting 14ish psi, but the car was buttery smooth, the SOUND was SOOO much better than my K04 (turbo muffler delete allows for a euphoric mechanical turbine spooling sound, almost like a jet engine but not obnoxious...I was in heaven), and the car pulled VERY hard. Over the next few days, continuously peppering Doug with questions and updates (he is in fact as good or better than advertised regarding service...you won't find a more attentive, responsive and considerate contact in the industry) I decided to remove the MBC altogether. My concern was the same as everyone's here...boost spikes, surges etc. (and this is my 2nd motor and 3rd turbo..with a kid coming I can't afford another catastrophe).
Let me tell you...on my Uni K04 file the car runs perfectly...I only boost to about 18psi unless I'm in 4th 5th or 6th (can just touch 20psi) but I'm considerably faster than I was K04. As a reference for you guys out there, we have a 2013 Audi TT-RS on my lot...check out the performance numbers for yourself, they're sick...but not sick enough to get away from my little MKV GTI!!! 2nd gear pull from 30mph through 4th gear I was all over the rear bumper of the RS (was behind thinking he'd pull on me and side by side wasn't an option where we were.) I almost lost my marbles when the same results happened with the next car...a 2014 Porsche 911 C4S (we have a Porsche dealership here too). Although it wasn't a perfect chance my best friend has a VR6-T Jetta pushing 450+ and my buddy from service here has a Stage 3+ MKIV GTI...I'm SLIGHTLY faster than both of them doing 35mph rolls...and all this is on my K04 tune.
Talk is cheap, as you can see I don't post on forums very often at all, even though I've been a member here for years...I'm 34 and don't care much what the internet crowd has to say about my car, it's my car and what I think is all I'm concerned with. Also, I know cars pretty well and have extensive knowledge and experience with cars (but I'm not a mechanic with full understanding of all the intricacies this engine throws at us i.e timing etc.) like the V10 R8, RS-7 (both in my showroom right now) so it makes me chuckle to see a lot of the online chatter and BS being lobbed back and forth by people who either don't own or don't know certain products. I also have logs to share that I think will be of interest to people, admittedly logging is relatively new for me so I'm not the best at looking purely at the logs and telling you what I see, but take a look below...feel free to hit me up with questions etc., if I can answer them I will...and a big thank-you to Doug, who was there when I had questions (daily for months) and even when I admittedly got a bit upset waiting for the new mixed flow prototype to be ready, built and shipped to me) :thumbsup:
