Also the most underrated series on YT!

Easily one of my favorite channels for this year. Thanks for taking us along on a cool project.

As a BMW HV Master Tech, I have a lot of experience with cars. I love all the engineering going into this project and how you are tackling integrating everything together. I love the content! I’ve been showing all my coworkers. Keep it coming!

Incredible work!

This is absolute GOLD . Ive very much wondered how you draw this kinda thing up from a scan. Thankyou so much for sharing .

Man, a 13b i8..that should be fun. I always wanted to put a k24 turbo in one

As an Einstar owner, I still grab my mirrorless camera and Agisoft Metashape to create a 3D scan of a much higher quality.

Nice work, will be following! It’s a bit of extra work but I have a video on using GOM to pull geometry from a scan and bring it in to fusion (Part 1 of my scan to part video scanning a VW MQ500 gearbox). Using an “OK” scan from a Pop 3 I’ve had measurements on bores within around 0.02mm repeatably and about the same positionally. Providing you have just part of a reference surface it extrapolates perfectly and doesn’t rely on trying to get a mesh section working well, generally a lot more accurate when it comes to needing geometry for dowels and alignment 😎

Great video I love how you showed how to go from scan to sketch

Keep this up, rising star in a flooded YT genre, you have a great unique approach/presence and an awesome project. 🙌

Absolutly love this build,all the details and design process that you go across is amazing and inspiring really,the exhaust and intake looks awsome,keep working hard!

Wirh friends, we always played wirh idea of rotary swap . From something like FWD Trabant to skoda 120 (rear engine) wirh Weber's...but now ... I hate say it ,but sir ,your swap sound and looks way cooler

Quality exploitation and showing

@garyhowe88 Ай бұрын

Try changing your location to UK, loaaaaads of mechatronics on there currently, also can use the tdi mech and just have it reprogrammed.

Haven’t seen overwhelming results for the PN I need of obh927711c

@LuisGonzalez-ds5mj 8 күн бұрын

Hi, get the mech unit from many models that use Dq500, the only differences between the transmissions are the gear ratios. You can get custom tuning from someone like TVS and have the gear ratios adapted.

@NavySturmGewehr Ай бұрын

Are you able to specify cut quality? They're cutting the profile pretty fast, but it was hard to tell how they did on the holes. I wonder if they just hone them or drill them after cutting.

@CouchBuilt Ай бұрын

Thanks for double dipping!

@tababobi Ай бұрын

Quite normal that the dowel pin holes on the scan might display slightly different diameters, the actual common value of which you can just set on the sketch from a reference or part spec search. How best however to establish each one's actual center, without worrying about a scan error of the order of the shown scanned diameter differences, if a trans is not at hand to check, for example, by superimposing a print of the sketch? Thanks, and great explanation of procedure to follow.

@censoredialogue Ай бұрын

an LS fitting in the subframe lmao…truly no limits to where you can stuff that thing 😹😹😹

@CouchBuilt Ай бұрын

Transmission for the LS is a bit more challenging, but I’ll do a video on alternative swaps in the future.

@frongicide Ай бұрын

Check out a transverse LS4/4T80E combo :) It's not a direct bolt on as you have to do some clearancing, but it is solid and had been shown to handle 800hp in FWD W-bodies.

New to the project. I'm curious about the high rpm of 13B and the dq500s internal oli pump and possibly other parts not meant to rev that high What is the plan/thoughts?

@CouchBuilt Ай бұрын

It’s a turbo motor, so it doesn’t need to rev to 10k. Based on the 8374 dynos I’ve seen, it should be good to shift around 7500.

@Jonny_trans Ай бұрын

You will want a oem Audi pilot bearing.

@CouchBuilt Ай бұрын

The adapter is effectively the pilot. Everything is directly coupled and rotates at the same rpm. The only time a pilot bearing is relevant is when there’s a speed differential between the shaft and the assembly it passes through is not directly coupled.

@Jonny_trans Ай бұрын

⁠@@CouchBuilt the Audi motor normally bolted to that transmission has a pilot bearing in the back of the crankshaft. I have personally seen issues with clutch adaptation if that is removed. Also the clutch cover seal on the input shaft will leak It wouldn’t be hard to chuck that aluminum adapter into a lathe and machine it for the needle bearing. This is assuming that aluminum component is bolted to the crankshaft and Audi factory dual mass flywheel

@CouchBuilt Ай бұрын

What you’re saying makes complete sense and I think the key word there is removed. That leaves the input shaft free to flop around and create havoc in the resulting void. The way the adapter interfaces, the input shaft is a close tolerate fit to the bore. If that fit is comparable to oem pilot bearing, the result is the same with no speed differential. I assume VAG assembles all the motors the same, whether manual or dsg for part number simplification. The bearing, bearings on manuals and simply locates on dsg installs.

@Jonny_trans Ай бұрын

This might surprise you, the manual transmission 5cylinder cars actually don’t have a pilot bearing. There is speed differential because of the DMF absorbing rotational speed fluctuations of the Eshaft/crank shaft. I pretty familiar with these transmissions. The dmf has a large range of motion. Upwards of 90°

Interesting stuff. I’ll take a deeper look.

How are you get the axels in it looks tight

Covered in other videos. Designed everything to fit.

@ralphmag3072 Ай бұрын

@@CouchBuilt I’ll have to look through this is the first video I’ve watched interesting build and I love the integration of CAD. Do you remember which video in particular you covered the axels? Asking because I’ve toyed with the idea of doing a DQ250 mid engined car with an 07K

@CouchBuilt Ай бұрын

@ralphmag3072 I believe my first intro video EP1, shows some of the axle location in CAD, as well as at the beginning of the Inconel turbo manifold CAD session. There will be more when it comes time to actually get the axles made.
