My first Audi - 2001.5 S4 with Custom Single Turbo setup...

Start with a 50 shot and work ur way up

But bigger is better! haha

Yeah a 50 will do the job... I'll probably change the jets... lol

[Schoolbus4]

U will be surprise what a 50 shot will do to a forced induction car

I've used nitrous anti lag before ;-)

[TweetsS4Estate]

I also dropped down from the #12 Meth nozzle to the #7

Did you buy a #9 also? That's what I think might be a sweet spot for 50/50 (I'd try maybe running 60/40 meth/water VP methonal helps more than people think)

All i can say now is "you are amazing" :D

You has PM

[Monty23]

You have the fx400 in there right? Or the twin?

FX400 :-)

Car sounds real healthy and seams to pull smoothly! What size intercooler core are you running? Maybe you're heat soaking a bit which might be why sometimes it feels slower than others.

Keep up the good work!

Thanks man!
It has some ECS parts lol

Here's a log plot from this morning as I was almost at work..
The Intercooler is a Treadstone 1035. It's 10" high and 3.5" thick... But... I don't have all of it exposed yet on the bumper. I have to pull the bumper and remove another 3" or so at the top... so there's a lot more cooling left in it.
This plot shows Power vs IAT vs AFR from the Wideband.

The car is a LOT of fun... 2nd gear is scary and 1st and 2nd the car often thinks its RWD lol.

[britishturbo]

Monty's 5858 vs my 6766 lol

[ECS Tuning-Audi]

Nice!

Intake temps seam a little high towards the top end but nothing to be too worried about. Was that on meth? Although you are probably just about at the max efficiency of that core. I wouldn't be surprised to see a nice gain from going with one slightly bigger later on - especially on spray. Back when I was big into EVO's most guys making over 600+ whp were running a core that was about 22-24in long X 12-13in X 3.5-4in thick - was good for 900hp.

Definitely let the one you have get as much moving air to it as possible.

That's not fair. I'm taking my ball and going home.

With Meth.
Intake tract is exposed to underhood temps though too still, that isn't finished yet lol.
Plus the core is 1/3 still blocked...

Word, any plans to run race fuel?

Wow i wouldn't even know where to begin with all this. I just wish I was able to do this with my 2001.5 A4

Monty's 5858 vs my 6766 lol

Just wait till I have my 5858 with built heads, RS4 IM, and larger hotside......it wont fall on it's face like his

[Monty23]

When is this happening?

[britishturbo]

That's not fair. I'm taking my ball and going home.

LMAO and both cars run the same FATS time haha

But... shifting at 8200 RPM this morning from 3rd to 4th dropped me down right at about 6300RPM in 4th... right in the peak power range... it's quite nice lol.
Full boost is hit again by 6500 or 6600 rpm judging by the logs.

You'll find it runs out of steam.
The 58mm comp side just won't move enough air to get much over 550 peak HP and certainly won't move enough air to make that much power at 7500 in my opinion...
But good luck.

If you want power till redline and not just around town... then the 5858 is too small.

[Monty23]

Party time!

[britishturbo]

Party time!

Yours is polished that's no fair... lol
What size is that outlet? 2.5"

[britishturbo]

Party time!

It's interesting how mine has the more traditional anti surge housing compare to yours:

[britishturbo]

It also looks like the 6766 would eat the 6262 lol

I'm thinking of trying E85 this week after I add the Nitrous and test it on pump...

you really think it's the turbo and not the stock heads/IM/small hotside? Anyone have any other dyno's with 5858 to compare?

[spd579]

When is this happening?

Probably wont have it together until late summer/early fall right now getting engine sorted for assembly. Gettting stock pistons(skirts and tops), piston rings, main and rod bearings all coated. I'll be dropping off block and rotating assembly for balancing, honing and headwork. All the listed before will be done in June.

[britishturbo]

Sure I think everything else is restrictive too... but the turbo can only flow what it flows...
I just don't feel the 5858 can move enough air to make over 500 to 550HP

[britishturbo]

I forgot to show this before...

But look! All gauges work, the center display works, and no Check Engine Light lol.

600+WHP and zero codes when scanned is fun stuff lol.

[britishturbo]

A little cruise video... nothing special just showing how docile it is when needed lol.

[britishturbo]

And other video showing the gauges.
My fuel trims are 0.
I spend a lot of time dialing in part throttle not just WOT.
The best way I can describe part throttle is like it cam from the factory that way lol.

[Monty23]

Fix the date and time lol

[britishturbo]

Fix the date and time lol

That's the date I dialed in for 88.8MPH though! lol

[Monty23]

bwahaahaa.... what funny is I was thinking back to the future when I saw your date too lol

you might be right.......maybe a 6262 is in order........hopefully I can see a 5858 with a larger hotside dyno to confirm some things before I finally decide.

I could just throw the 3071 on and shift at 5k lol

[britishturbo]

My work made a product called the Flux Capacitor... and I'm not kidding lol.

The wonder of the top mount single turbo is that you CAN try different things :-)

I concur..... its so nice being able to swap turbos in the same amount of time that it takes to change your oil
