I've heard of people making that much without any porting just exhaust, ecu, and tune. A mild little streetport would practically guarantee it on top of those other parts though

Looks nice, but I would have ditched those diffusers in the exhaust ports. I think someone sells just the turbo sleeve, or one can just use turbo rotor housings if one needs to replace their housings. Oh well too late now.

I put down 156 a couple weeks ago with my s5 6 port. Has a k&n drop in filter, no emissions, 6 port sleeves/actuators removed, vdi wired open, safc, pacesetter header and a 2 1/2 exhaust that was made out of scraps with 2 full size magnaflows.
And found out yesterday the header is cracked all to hell around the o2 bung and the exhaust sleeve in the rotor housing is broken as well.

the iron intake path is fine for 200+(street ported primary, even without the semi-PP), the stock exhaust port with diffuser is only good for about 175whp, the stock intake manifold is also again only good for about 175whp. so you can see the areas that need work to make numbers.
with the current configuration i'd say you will be hard pressed to go further than 185whp without redoing the exhaust porting and using a decently modified intake. all others that made 190-200+ used TII sleeves and ported exhaust, so the numbers can be skewed slightly but the bottlenecks will always hold you back if not addressed.

We shall see I guess?
The intake manifold is @ the machine shop and hopefully done by tomorrow.
Can't wait for dino day.

regardless i'm interested to see how it turns out, i personally haven't had much luck spending hours on the dyno with a "winged" exhaust port S5 engine. he replaced the engine with a stock port S5 engine with just TII sleeves installed and saw immediate results with the same tune.
the compression test just before the tune came in at 110psi all around so it wasn't due to an unhealthy engine.
just call me skeptical, all the major n/a power cars floating around have very aggressive porting, intake and exhaust mods done. not that a wing port sleeve engine can't make over 200whp but i definitely think it is working against you well before that point. it isn't there for scavenging from backpressure, it is there to reduce the raspy exhaust note at the cost of power to make the marketed cars quiet.

Well, I am sad, yet happy (given the fact I will have more HP with the same MPG) to announce. The motor has been opened up, installed low compression rotors, and TUUUUUUUUUUUUURBO 6 port here we come!
