why do you have a walbro and 3mm apex seals. And what size streetport?

 

i read someone made 210whp on a mild streetport with stock intake, they did have standalone. I think it was Yaw Power or something along those lines. Im sure they knew they were using the stock intake and ported accordingly, it just needs to be looked at as a whole package when your going for most power.

 

No im not. Few people have got 180+ on stock ports with exhaust and using the S5 intake on a S4 and removing air pump, PS and AC. Doing a street port would be usless if you are only seeing less then that.

 

because the previous owner is an idiot and did those things

its just a minor streetport.

 

Walbro should be easy enough to fix. And i think ive read that 3mm apex seals make less power due to more drag.......dont know how true this is but just a thought.

 

yeah it is true, I would be making more power with 2mm apex seals.

 

Your setup sounds alot like mine, Ive got a streetported s4 na from rotaryresurrection, racing beat collector/header, borla catback exhaust with straight pipe (no cat), racingbeat lightweight steel flywheel (yours is lighter), centerforce dual friction clutch, kn intake, bonez maf adapter, corksport intake kit, removed 5/6 ports, ported throttlebody, 8.5 mm magnecore sparkplug wires.

For weight reduction removed a/c, ps, airpump, and all emissions equipment and rack, removed interior rugs.

I did uprade to 5 lug conversion, dont know if yours is still 4 lug. I could use an lsd but I am getting some Kumho Ecsta Spt 205 50 15's put on which should help my traction out compared to my last set of tires.

Im assuming now I have about 180-190 hp, but I know I could use an safc and a dyno tune on wideband.

 

lol basically we do have a similar setup, but yeah I have 4 lug but I got TII front hub assemblys, im just waiting to put them in for a while cause I got 'big' plans for this car.
