britishturbo's Single Turbo S4 2014 Build Thread

[britishturbo]

So I decided to make a new thread for my 2014 build since my original thread (http://www.audizine.com/forum/showth...le-Turbo-setup) exploded into such a huge thread.

Currently a work in progress but here's the recipe so far (At least what I can tell you ;-))

3.0 Stroker Engine:
JE 83MM FSR Pistons - 10:1 Compression Ratio
JE Tool Steel Wrist Pins
Integrated Engineering Rods
ARP 625+ Custom Aged Rod Bolts
ARP Custom Main Studs
CNC Ported 2.7 Cylinder Heads
+1MM Supertech Intake Valves
+1MM Supertech Inconel Exhaust Valves
Supertech Solid Lifters
LOBA Solid Lifter Cams
83.5MM Head Gaskets

Billet Dry Sump Oil Pan w. Integrated Girdle
Peterson 4 Stage Dry Sump Pump

Borg Warner EFR 9180 Turbo w 1.05 AR T4 Exhaust Housing
Quick Spool Valve

Direct Port Nitrous

Megasquirt 3 Standalone Engine Management System

There's more but I forget right now... lol

Now some pretty pics for you to enjoy for now...

Sweet!!

Any thoughts on using the turbo rpm sensor?

[OMGHI]

In, so when someone finds this thread 3 years from now I can say "I was there". But for real, excited for your build !

[britishturbo]

I will be. Will log with the MS. Can use to prevent over boost.

Nice! Thats gotta be an extremely powerful/useful sensor.
Especially if the MS is setup to use it.

[jibberjive]

Woot! New build thread for you.

[millerchris85]

Excited to hear about your tuning experience with the MS on an S4! MS2 on my Miater

[S4 00 2.7]

Very nice.

Is there an ending goal for this one? Or the goal is still to "go" until failure lol.?

Pretty sure this one will be built to last......at least 20k miles ha

[spd579]

Is there a reson why the skirt is so small? I dont recall seeing a skirt that thin before.

That's like 20 years for an engine of Lee's

FSR pistons. Have an assymetrical design for reduced friction and weight.
My rod and piston combo is lighter than stock by quite a lot.

Haha truth!

My goal is 901whp
And 10.5@140mph at the track.

That is all ;-)

[MileMan402]

If you don't go sub 10.5, you're getting deported!

[MileMan402]

Why not a custom geared trans?

I like to set easy goals. ;-)
Haha

Because I am poor... :-)

[sherbet]

Would someone please enlighten me on how the quick spool valve works?

I think you should do a sponsorship deal with ppg since they are in development of awd 01E's. I'm sure they would give you a shot.

Scotty has custom sets as well.

Do you think this would be beneficial to me? 8374 divided t4 3L If so, what could I really expect? I current expect to have close to 30 psi by 3500. Does the use of this make it any more complicated to tune? Any risks at all with the use of this?

"The Quick Spool Valve has a butterfly valve blocking a scroll of the divided turbo housing, making the turbo act as if it were a smaller turbo. All the exhaust energy is routed through half the turbine housing, causing the turbo to spool at a much more rapid rate. In other words, the spool valve is essentially "halving" the turbine A/R when the valve is closed, and then you get close to full A/R when it is opened. For example lets say you have a .86 A/R 76GTS turbo. With the quick spool valve operating, at lower rpm's it acts like a turbo with a .43 A/R housing, which means it spools very quickly, shifting the power band downward on the curve and allowing for much quicker build up of hp and torque! When the valve opens, you end up with about 95%+ of your total A/R available and full boost."

Essentially makes your turbo small(k03ish) at low RPM for better spool then after it's built up boost makes it a large turbo(gt99ish).
