What is the most power any one has got or can get out of a n/a 13b. im curious, my friend toled me about a guy who got 350 to the wheels but that seems like alot thanks

 

you can get about 200 "reliable" rwhp out of an NA. it requires a good deal of money. for less money than an NA build up costs, you can do a 13bt swap and put out more power anyway.

 

I would say that 190 is about the most you should hope for, and thats with a good streetport and a standalone ECU.
As for the guy that said he got 350 from a NA 13b, hes full of crap. It is theoretically possible, but only with a mega high-dollar PP engine that is totally unusable on the street, and its pushing it even for that engine.

 

so no one on this forum call a bridgeport reliable at all?

350hp? I was probably done through one of the highest styles of porting... P-porting(search it up) very expensive, very technical(you need to know what your doing) and are generaly used for Track use only... although some have/are doing it for a budget, 10k is the round about for it and you could make 350hp off of a TII with about 1500 in tuning alone...

like the above said, 200hp is about the tops without doing other serious stuff... besides, 200hp is enough to move that FC around quickly

 

i thought 350 was quit extreem. i was just trying to find a way to do somthing dirent then every one else is doing.

 

what does an FC put out stock, maybe 120-130 rwhp? if your engine has good compression it will put out about 80% of your stock crank HP. put a good full exhaust, intake with heatshield, replace all vacuum lines, good spark plugs, oversized spark plug wires, remove secondary throttle plates, and bore out the throttle body you might put out 160 rwhp. install an electric air pump and remove the AC for another 0.5 HP. Then just strip a few unneeded things from the car for some weight reduction and it should be pretty quick. a port job and better fuel management might put it up to 200 rwhp.

 

I can think of 2-3 N/A's I know of that aren't PP and make 240-250 RWHP around me. My bridgeported ITB Haltech setup will push 240+ I bet.

 

240-250 is doable with a bridge, but it won't be what I consider a "reliable street car."

 

Why not? I can't see why a BP would be any less reliable then any other porting job as long as the porting was done with quality.

For S4s, to up the HP you can install the S5 intake mani and could install high comp rotors. Exhaust is a big deal when trying to reach for the highest HP mark.

 

Its not so much the reliability as it is the streetability. I realize you can drive them on the street (hell, there are people that drive PP's on the street) but its still not what I would consider a "street car."
