How to get to 230-240 rwhp on my s4 t2?

How do I do it, without turbo upgrade, and without ecu upgrade?

Uh...I don't even know how to respond to that.



-Full 3" exhaust (Racing Beat, Corksport, GReddy, Apex'i, etc.)
-720 secondaries
-SAFC2
-Walboro 255lph fuel pump
-3" Intake (D.I.Y. from home depot is fine and cheap..)
-Cone filter w/ some kind of heat shielding..
-Full tune up All oils, spark plugs, coolant, etc.
-Will all of this done, BE SURE to port you're wastegate, as with the 3" exhaust and intake the turbo will boost/spike to up to 18psi..as a note, the stock turbo should never go over 12psi (any higher will actually make less power, due to the turbo pumping hot air)

Well, you said WITHOUT ECU upgrade. This actually CANNOT be done. The stock ECU has a fuel cut to the rear rotor if you hit too much boost. You have to AT LEAST have an FCD (Fuel Cut Defenser)..You can get one of these real cheap, or make one yourself(search), or, if you want to have you're car set up to run on 720's, you can get an RTEK 1.5/1.7

Now, all of this should set you at around 240whp I'd say. If you want to do this really safely (which should be you're agenda BEFORE horsepower) you'd want an aluminum radiator (Koyo works), and a FMIC (ebay's work just fine)

- port the wastegate
- bigger secondary injectors
- bigger fuel pump
- S-AFC
- boost controller
- full exhaust
- intake
- and a good tune-up

I did this a got 244rwhp @14psi with a few other things.

these things might free up a few more ponies if you have the budget.
- dual alt pulley (remove smog pump)
- lighten flywheel with a good strong clutch
- lighter wheels and tires
- good suspension setup
- aftermarket intercooler
- S5 turbo and manifold

if you have the 1.7 and a full tuneup, then you should go see what you put down at 12 psi.

FCD = boom

the racing beat type FCD
can not respond fast enough to prevent fuel cut
when you have a free flowing exhaust

I hate them with a passion

a reprogrammed chip is the only real and accurate solution

I used an RB FCD for a couple years with no issues... Never ONCE experienced fuel-cut with a full 80mm exhaust/hybrid turbo etc.

You need a full exhaust, an FCD, a fuel pump and a fuel pressure regulator.

rtek= FCE (eliminator)
POS Racing beat = FCD (defender/tricks the ECU)
