worked on a stock engine 87 n/a.. I fixed the 6 port actuators.. got them to work correctly and did some dyno pulls. got 134rwhp and 116tq.. cars has a header, intake apex afc.. air fuel mixtures were at 13.2 I figure with some msd's better spark plug wires. cold air intake, complete streetable race exhaust. could pull about 170rwhp with the stock ecu and factory air flow meter. not bad for stock tired 6 port..

 

What, no nitrous? Ha ha.

 

i bet my old blue n/a had even less power!

 

Yeah, my S4 block in my S5 FC ran 117whp.....my god was it slow.

 

my old 87 with full ehxuast and intake did 133 hp and 115 ft lbs

 

I think my car has 160-170 whp right now without even being tuned.



Mine is streetported,corksport intake kit with heatwrap on it bonez maf and kn filter, racing beat streetable header, straight pipe in place of cat, borla catback exhaust, removed 5/6 ports. Lightweight steel flywheel (racing beat), redline synthetic tranny and differential fluid. 8.5mm Magnecore wires. Ported throttlebody.

 

umm dyno it i bet you do 150hp max. its alllll about the SHEETS!

 

Cold air intake, good flowing exhaust, and the S5 Intake manifold should put you close to 170.



Check out Global Vicinity for more information on getting some extra ponies.

 

I have 2.5" Single exhaust, S5 Intake Manifold, AFC (not tuned but added fuel at the top end, much bigger kick in power), basic cone filter, soon to have a 3.5" cold air intake, ported TB elbow and modified TB shafts. Right now without a cold air intake, it really has to be cool outside for the engine to give some power, but when it does, at around 5000rpm you get slamed into your seat. I have power till about 7600-7800 on the good days. I have a few bugs to work out so I hope to get that consistant.

 

my friends 223K S4 n/a with CAI, Racing beat Header/Silencers, FC 1000 ignition Magnacore 10.5mm spark plug wires, Gil mer belt drive, and a e fan did 154.6 hp back before it was swapped with a 347 stroker ford V8
