MDUBZ Intro and B6 S4 Build Thread

Stage 3 Rs4 ya say??? What is that? an even bigger supercharger?

not sure really. From conversations I’ve had with JHM people, here’s what I think is accurate:

stage 1 RS4 is the supercharger with no cooling system, running super low boost (6 psi). Good for around 400-425 whp (YDMV) and high 11s @ 116-118.

stage 1+ is the above with an intercooler…and I think a marginally smaller pulley/more boost. Not sure what that is good for. When this was on Dan’s car, he trapped in the low 120s and ran mid-high 11s.

stage 2 RS4 was supposed to be 9 psi and be good for 500 whp, and around 125 mph of trap, low 11s if driven well. This level of boost has been determined to cause some problems for the RS4’s engine, so JHM is hesitant to make this available for widescale retail release. I think if you want this on a stock engine, you will need to sign a pile of waivers that are about as thick as a rural phonebook.

stage 3 Rs4 is presumably built motor RS4 + lots of boost on the same blower. This is currently running on Dan’s car right now (the built motor) at lower boost but they will move that along over the coming months. This will be retarded strong.

stage 4 RS4 is built motor + bigger supercharger. Think about that for a minute. The V3Si they are using for stage 1-3 is good for around 650 whp. But it’s not big enough for stage 4.

Those 3 and 4 cars…not sure how many people will actually buy that, but I do know that what we see on forums is basically a tiny sliver of the market (grand scheme of things). For example we know of what…5 JHM RS4 supercharged cars on all of the forums (SAR in UK, Denis, Badtoyz, couple of others)…well JHM sold 5 superchargers in the last month, and have sold a few dozen and we have no idea who those people are. They have sold a pile of built motors for the B67 S4 but we know of exactly 2 (mdubz and the wagon from norcal). So we’re not seeing anywhere near the big picture.

Damn, everytime I turn around there is one more stage! Well that makes sense now why we haven’t seen many stage 3’s or why the kit isn’t really advertised either. I feel like if you shelled out the money to build the engine, you might as well take her the whole way, get all the horseponies.

Maybe stage 4 can compete with this 830whp rs4 - https://www.youtube.com/watch?v=cbtiU-ZniNw

lol le jokes, actually the guy is a local and he owns the body shop that fixed my car when it was rear ended. that 830 whp is more like 350whp on a good day. Pretty sick setup though, cameras intergrated into the front and rear license plates, custom euro rs4 seats with matching back covers, crazy amp setup in the back. The meth kit looked like a pretty cool install too, one of a kind stop tech brake kit, but i think it was a pes blower, i don’t remember but it wasn’t 830whp fast.

See, I just don’t get that frankly. It just seems, well shallow I guess. Triumphs and short falls, thats what life is about. I’m going to track, wait, no I’m not unless I do well and run a good time because I don’t want to look silly. I guess to each their own. Have fun mdubz. That’s all that really matters. Of course we want to project and see you achieve success but no reason not to share your enthusiasm in case you’re not.

If a tree falls in the woods and no one is around to hear it does it make a sound? If my car goes 13’s and nobody saw or I don’t report the result, did it not run 13’s? Lol!

It seems ‘shallow’ to be private? Interesting. I think it’s just a matter of being private. Case in point, my B7 S4 did pretty well, however I never posted about it in advance. I just went about my business and when I had something interesting to share, I shared it. There had already been a bunch of B67 S4 guys who ran great times ahead of me on the forums so it wasn’t like I was going to do anything groundbreaking. I just shared what was relevant.

when there are legions of morons parading around the internet forums on a crusade against JHM for literally no discernable reason other than they got owned by people who own JHM parts, do you really need to make yourself canon fodder in the name of ‘life’? I think you’re taking internet forums a bit far.

Further, you haven’t been talking big numbers to legions of B5 owners on multiple internet forums and platforms…but MDUBZ has lol.

I take the forum too far? That’s rich

Was Peter Griffen int he car with him?

MDUBZ · December 8, 2019, 5:12pm

Lol. Whoa ho ho… holy crap!

mec · December 8, 2019, 5:12pm

So…you gonna be back for July 3rd? A group of us Audi guys are going to High Plains Raceway, you should show up and set some benchmarks.

MDUBZ · December 8, 2019, 5:12pm

I’ll be back this Friday in time for the Pikes Peak Airstrip Attack. You should come. If you bring your helmet you can jump in the car for a race or 2 as well. Let me get back to you about July 3rd. I think I can make it but I need to double check.

mec · December 8, 2019, 5:12pm

Deal! Looks like you have to buy tickets right? Which day are you going to be down there?

MDUBZ · December 8, 2019, 5:12pm

Saturday. I need to be there by 8am since I’m racing.

MDUBZ · December 8, 2019, 5:14pm

Got a little video from the California trip. It was about 95 degrees out in Lathrop but the car pulled like crazy. If you watch closely at the end you will see JHM on the right side of the screen. Enjoy

JimmyBones · December 8, 2019, 5:14pm

Nice man. The JHM intercooler really makes a big difference.

I have been there before.

pwest15 · December 8, 2019, 5:14pm

That’s epic man! If you’re free any time this week you should totally stop by my place so I can maybe get a ride

happy2b5 · December 8, 2019, 5:14pm

Yep, wonderful central cal summer weather. Dont miss it one bit. Car sounds strong.

sakimano · December 8, 2019, 5:14pm

what happened at the Sac dragstrip? How about the pikes peak airstrip event?

MDUBZ · December 8, 2019, 5:14pm

It makes a huge difference. I actually didn’t realize until I spoke with Jason that he actually fabricated that intercooler. If I loaded it with ice I would have seen at least another pound of boost, maybe 2.

For sure man, you working on the car this weekend I’m assuming? I’ll roll by to help and go for a cruise.

Thanks man, yeah it sucks, but it was better conditions than I’ll ever see in Colorado.

Ended up getting the car back Friday night rather than Wednesday afternoon. They applied a ceramic sealant to the engine so it’d stop chugging coolant which took a few days. I rolled into Sacramento around 8:30pm which left me with an hour and a half to unload my car, wait in line, and maybe get 1 run in. It was also going to cost nearly $100 for the 1 pass and waiting in line so I just gave up.

Pikes Peak Airstrip Attack was the next morning so I didn’t have enough time to make it. Got home around midnight on Saturday.

I’m going to try and make it back to Sacramento in November for the JHM Sacramento drag night

cool. Will be good to see it run in good conditions rather than the heat.

We have a drag night next week ;D

Jake · December 8, 2019, 5:14pm

A cool thing about that video is you are going up an incline too

MDUBZ · December 8, 2019, 5:15pm

Used the rest of my vacation time to come out there last month >:(

I should have enough by November though

justincredible · December 8, 2019, 5:15pm

wow your car was moving in that video. Sounded so good. Looks like your shifting is getting a little better. keep working at it and keep the updates coming

MDUBZ · December 8, 2019, 5:15pm

Thanks Justin. Still working on that 1-2 shift. I feel like I’m pretty good at nailing the 2-3 shift, just not quite perfect yet. It’s really hard to improve when you only drive 2,000 miles in a year and it’s all city driving. My cruising shifting is pretty damn good though Hoping to get some racing/track videos soon.
