Audi A5 3.0TDI CCWA with 6hp - old hybrid removed and BSR Spec installed 

Hi thanks for commenting. Yes I do try to avoid random turbos unless the spec is good. Im sure there is a market for lower spec hybrids but for me if Im doing a job it needs to be right. As for the tuning - you seen the vcds screen but Im seeing tuning like this all the time now. This guy also installed a wagner so that helped. If you need help in the future you got my details 👍🏽

The old spec could have performed also good. Just PCV change (if all support mods already in place such as ,wagner,cp3, swirl, agr,dpf off, maf, map sensor...) with proper tuning the car would have also performed great. 400hp / 800nm+. Usually those hybrids running amg "lightweight" turbine wheel wich i consider not that bad to be honest. The 65mm inducer wheel (i would assume) is also good to support 400hp. Is there more to get, of course but sometimes (very often) there is an invest/ performance tradeoff to be made, especially for just those "last" 20-30hp more you can get with the highest 2260 hybrid spec. On top spool is also suffering at least in theory. I would love to see bobby open himself to tune more "selfmade builds" as fucked up as they sometimes are specially at software side but often there is just one piece of the parcel to change (also in this case) and everybody would be happy.

@@SSC0815 I agree power could have been better. However there is more to a turbo than just wheels. For example if the machining work is done poorly this also results in inefficiency. The tw you mentioned was first tested by myself in 2016 and yes it works fine. If you have a turbo you want me to tune I’ll do it but I cannot say how well or how long it will last. I recently tuned a hybrid with a 54mm wheel and it surged terribly in the low rpm which meant less boost. He’s returning to have my spec soon. Most cw’s out there being sold are not suitable for diesels - people just assume bigger is better.

@@SSC0815I got problem whit this pcv on the beginning I didn’t know they are limited with pressure and often I got limp mode because of that but I didn’t know from where it’s coming and no one know, now I know after Bobby move:D it was hard to get 400hp from this turbo because they max boost was 2bar anyway we stretched to 2.1bar in middle range. Other than that spec was not bad in my opinion got all supported mods like: bitdi maf, 2200bar fuel pressure sensor, cp3, big brakes from a6 etc. The biggest problem like you said was proper tune… and I’m sad too, that Bobby don want to tune home made project but on the end of the day it make sense why Bobby don want to do this.. Ps: Dpf wasn’t gutted by my:D was done before I bought car and now I saw how bad it was… especially because im doing welding for living. Thanks Bobby again for finishing my project!❤

@@radoslawslupski516you are a very humble guy my friend. I appreciate it 👍🏽

Thanks - I do other engines and brands 👍🏽

Thanks

Good point 👍🏽

If tuned progressively they can work. These turbo names don’t mean much without wheel sizes. R110 pump is a over kill for the power level.

You have manual a6? cdya. I have tiptronic, can it handle power?

@@mrpatonki6776 you have a 6hp19 and yes they can take power if torque is controlled. I done 400hp / 800nm a few times now.

@@mrpatonki6776 yes i have manual gearbox. With a new Sachs dual mass flywheel. A stage 2 pressure plate that can hold up to 800+NM. And a 8 Puck clutch without springs. They don't exist with springs for the c6 to soften the gear changes. From standing still to first. Engage first gear . the car judders. After that it drives normal. About tiptronic i don't have the knowledge about that.

@@BobbySinghRacing I feel like it is very risky, how can i make my 6hp19 stronger, like 6hp28?

Hi it can work with a gutted dpf but obviously to gain the max from the set up a 76mm downpipe is recommended.

Best to ask your tuner. If you look at the compressor map you’ll know.

76MM dp is good - what spec is your hybrid and have you measured the emp?

​@@BobbySinghRacing it's 6 pal to 7 pal and 36mm to 38mm increase i remember. No i have no idea how to measure emp. It's leaking between turbo and catpipe, it's bent. My low rpm's really weak when i push throttle less than half, i got p0299 dtc three times when going up hill last month may cause of bad quality diesel. I have inspection this month, after it, planning to install dp and 4bar sensor then retune. Is 6hp26a or 6hp28a gearbox swapable over my 6hp19a ? I read that some a6c6's have this transmission.

Hi sounds like a vibration causing the issue. Maybe engine mounts or some heat shielding? hard to say

Are you planning on bringing me the car for tuning? if not then this question is for your tuner.

Because the previous tuner tuned off the engine protection for exhaust, oil and coolant temp. Its not correct and not very safe especially if doing vmax

I guess its not a wagner and some cheap ebay item. Read about pressure drop

@BobbySinghRacing yes its a custom made that fits ccwa/capa engines.

@@vehtech9699 then just buy wagner - if you want I can sell you one at 10% off retail price

@BobbySinghRacing shouldn't the flow be better. could you please explain about the pressure drop as it why it's smoking ?

@@vehtech9699 1) boost leak 2) the intercooler efficiency is worse than stock

Haha 6hp is the gearbox type 😀

@@BobbySinghRacing ohhhhh lol I was thinking hang on a second 😂

@@QuickShifts_😂 👍🏽

You need a programmer like flex or so.
