Oh My! that is going to be the fastest B6 the world will ever see.

Not in a strait line but plenty fast around the track.

[kwik_shift]

wow, i think i just wet my pants

[AudiA4Turbo22]

Not in a strait line but plenty fast around the track.

i think u might even hit straight line, u shed quite a bit of weight and that turbo is no joke.

[tdmopar59]

wow... what is this whole setup?? lol I'm pretty new to this audi thing and i've never seen something like that!

[absolutegtr]

deep, deep down...I would love to take your approach and do the same to my car (I am refferring to gutting it)

[Will_02_A4]

Is this a joke. Like honestly that thing looks crazy! Keep it up and keep us posted.

Looks good Mike, but aren't the bends in that manifold going to hit the engine mount? This is one of the reasons Full-race wont make a Vband tube manifold. The tubes hit or the turbo ends up way too high.

[7speed]

guess we will soon find out

Well I hope not! I'm assuming he knows what he's doing and work around the problems.

Actually Full Race offered us to make their manifold with a Vband set up.

[KraftwerkB6]

looks sweet Mike.

I know. Geoff said he would do one for me, but the turbo ends up much higher since the collector needs to be longer. Problem with that is my turbo already sits very close to the hood, if sits even higher the hood wont shut at all.

[IronAudi]

Can someone explain the difference and the gains by using a setup like this? Im not really all that sure of even what im looking at.

[durfA4]

WOW that is very impressive

for Iron Audi, Jet Jockey has done what most of us fear to do, he gutted his car down to removing unnecessary wiring harnesses, and did everything RIGHT. now he has put his focus on the engine.

He is having custom exhaust manifold made to fit in his car, and the V-band design allows for a smoother transition into the turbo, allowing a quicker spool because the velocity of the exhaust gas is not hampered by changing sizes and flow restrictions. In other words he is taking the time to make the car what he wants, how he wants its, and that is perfection.

[mike-2ptzero]

You must be comparing it to a log manifold. Because even a well built tube manifold with a T3 or T4 flange will be smooth going into the turbo if the collector is made correctly. Mike went with the Tial mainly because it is much lighter.

Mike is essentially correct. The weight savings were important for me.

The Vband does allow some more freedom in adjusting the turbo on the flange because it can be rotated and is not stuck using a pre determine position by the bolt/stud holes in the flange.

BTW Mike the Clutch Master FX600 was just delivered at the shop in VA, Thanks!

Looks crazy, your threads should be saved into a DIY of how to make a track car right.

what size inter cooler are you gone to run ?

Will you have to have something supporting the turbo so that it wont eventually wear out the V ban clamp or will the manifold and exhaust be enough ?

[Arclight]

What an awesome setup...can't wait to see the final result.

Here's my new FMIC during a test fit on the car (already pressure tested).

It's a Setrab core and its part number is 58-50012-90 and its size is the following;

19.75" x 8.0' x 3.5" with 12 rows of high efficiency tube and fins design.

Yes we are planning a support system for the turbo and it will be a special one I can assure you. Pictures to come in a later post. I don’t know how critical it is required to have a support (I won’t take a chance) but because I chose the TiAL housing the 3076R is only about 1.5 lbs heavier than the K04.


Setrab FMIC set up...

Sweet, more power i like it, good job man keep us posted... Thanks DurfA4 and Mike, i udnerstand now.. dam 3.0slow :)

[dewey527]

that is unbelievable! i thought the brake setup was awesome...

[Killerteve]

Those Tial v-band hotsides are so hot. Everything is looking awesome so far. I wish you a problem free completion of the project so we can all see some vids of your monster on the track and hopefully a record breaking dyno. When do you estimate the car will be running (I know you don't want to jinx yourself so let's estimate lol) mid-spring beginning of summer?

[A4 Moda]

Very Nice work

[Maverick]

amazing workmanship and a lot of effort.

I hope the engine built and engine dyno break in and tuning will be done by March.

I'd like everything back together prior to April.

We are not going after monster numbers. We plan to be conservative and the is that we can tune it on the engine dyno for 400 CHP on US 93 Octane gas an in the 470s-480s on VP MS109 race gas. We want this to be reliable and very smooth with power/torque down low and pulling up to the red line.

I intend to go on the Dynapak, Mustang and perhaps the dreaded MAHA dynos sometime later to see once and for all what X CHP on an engine dyno gives on several chassis dyno.

[dougyfresh]

Very conservative

But at least its a solid build that is done right. Should yield some good results on the track.

if thats true you could have gone with a much smaller turbo

[actlsub9]

"We are not going after monster numbers. We plan to be conservative..."

con⋅serv⋅a⋅tive: (adjective) Cautiously moderate or purposefully low.

[Jet Jockey]

Perhaps but now I have a lot of headroom to work with for future upgrades like if and when I get the head work done.

Besides, no one here that I know of did it like what I'm trying to do it that is, do it on an engine dyno.

You guys are always assuming that the 25% drivetrain loss is a constant which apparently it is not. That's why I want to wait until we have engine dyno numbers to then compare to several chassis dynos.

You see it is completely absurd to compare chassis dyno numbers to others because there too many variables. Someone’s 400 WHP on one dyno could be someone else's 350 whp. No more BS, I'll get the real number off the engine dyno.

[dougyfresh]

Another method is to dyno a stock 1.8TQM and the same day (within the hour or so) you dyno your vehicle (chassis dyno). We all know a stock 1.8TQM is around 170chp so one could calculated the chp on your vehicle. That is, if the drivetrain loss is constant regardless of power levels (some may argue it changes).

Albeit, the method you are using is the most accurate. I am really curious to see the outcome of your 'experiment'. Thank You for doing it.

Well I thought so too. But I have been told that this is not true by more than one person and who am I to argue with people with a lot more knowledge then I.

I may case I had 125.7 WHP when stock. On race gas and with my special MTM K04 I have now +255 WHP, that is more than double the stock WHP!

Are you telling me that my motor is now producing more than 340 CHP because I more than double the WHPs? I doubt it; I don't think a K04 powered car produces more than 340 chp. BTW isn't that what APR claims their Stage 3+ kit with a Disco Potato puts out?

What I'm told whether correct or not is that as CHP increases the resistance becomes less thus the drivetrain loss reduces somewhat. Also the type of chassis dyno used will be influenced by this.

I was told that if resistance stayed the same the metal in some of the car's components (drivetrain) would become molten steel.

[dougyfresh]

Valid points Mike.

Does APR have an engine dyno? I thought they did.

Unless they changed lately they have/had a Dynopak and I know that the numbers for the Stage 3+ were from the Dynapak.

Well you did trap 107 MPH, so either the tracks timing equipment was messed up or you really were producing over 300 HP.

[mike-2ptzero]

if thats true you could have gone with a much smaller turbo

But that means he would need to push that smaller turbo hard to get those same numbers that he wants to get with the 30r running at lower boost levels. Going this way was the smarter way because his IAT's will be much lower for that long period of time he is pushing the car hard on the track.

25%? A4 owners have been saying 22% for nearly 8 years. Lucas already done engine dyno and chassis dyno with his 2 liter GT35r. He made low 600hp on the engine dyno and then mid 400 on the chassis dyno.

22% is too low but a variance of 1% or 2% is possible. There are too many factors involved in saying that "a percent number" is the absolute number to use.


Assuming he got 600 CHP and he got 450 WHP that's exactly 25% drivetrain loss any less then 450WHP means he as more than 25% drivetrain loss.


600 x 25% = 150 or 600 x .25 = 150 HP loss through drive train loss.

Of course the dyno used makes a big difference too. We all know that some dynos are producing very high WHP numbers meaning they show a lower drivetrain loss and some show very low WHP numbers meaning they show a high drivetrain loss. Some dynos show over 30% drivetrain loss and some show in the low 20s. Which dyno is correct?

On the Dynapak I used from day 1 it showed my car had 125.7 WHP from the 170 CHP Audi rating. This means on this Dynapak my car had a drivetrain loss of 26%.

170 x 26% = 44.2 or 170 x .26 = 44.2 HP through drivetrain loss. Again this is on my Dynapak and someone else on another Dynapak may get different numbers.

Now imagine if I had my initial fully stock car dynoed on a high drivetrain loss machine or a low drivetrain loss machine all my numbers would be different.

According to a tuner I know very well that as had the chance to work on many models/types of dynos while tuning customers cars he says by far the most accurate dyno that will give you the "true WHPs and CHPs" is the MAHA. He says it is constantly within 5 CHP from the manufactures HP ratings when he dynos stock cars before mods are done to it.

That is why I want an engine dyno read out, a Dynapak read out, a Mustang read out and lucky for me we have a MAHA 45 minutes away from my house too.

BTW, the tuner told me the MAHA is the "crying" dyno because when people get their cars dynoed on it after being dynoed on other types they "cry at the numbers they get" on the MAHA.
