straight forward: how can my NA hit around 200whp if not more
i wanna know what it takes.. it seems Kahren can do nearly so with exhaust .. a port.. and a standalone... i wanna know what my potential is with an s5 NA ... gimme some ideas! thanks

there you go........ 193rwhp is as close to the 200 mark as ive seen (documemted) on a "streetable" NA rx7.....

Maybe a straight pipe replacing the presilencer and a better header (SDJ maybe) would crack 200 easily with Buzz 22's current mods.
Also a CAI.

well, I just pulled all of that out of my ***, but I'm sure it's about in the right direction

Kahren built an s5 n/a motor with his style of porting, TII manifolds port matched to n/a block, and an s-afc (tuned) with stock ecu. Car had rb header + straight pipe + catback also I believe.
Was barely under 200rwhp BEFORE redline, had to pull back because it was running too lean up top. The curve looks as though it would've easily hit 200.
And all of this on a stock ECU and an s-afc... It's really not as hard as so many people seem to believe.

Kahren had 195rwhp on stock ecu with s-afc... So in my mind 193 with standalone and a port means that either the port wasn't very good, or the tuning wasn't very good.

200hp isnt amazing unless its on a go-kart...lol
its possible to turn an fc into a go kart, no windsheild, roof, or much of a body, no doors, hood, etc. come on you die hard weight reduction guys jump on this...
but why does everyone want to reach 200 rwhp? i would much rather have 175 rwhp if its across a wide range rather than have a steep peak at 200 then drop immediately down

Option 1) Built N/A engine [$$$,BIG SP, BP, PP]
Option 2) Nitrous
Option 3) Turbo
That's how you can get more than 200hp out of your car. I'm all about options 1 & 2.

A) people who can't afford it
B) people who never had it
C) old people
The whole powerband/torque curve thing just seems like a pretty common excuse people use when it turns out slow.

he loves boost. and he's a showoff, and hes 65 haha
so not all old people don't want boost

With the engine I'm building, I'm going to try for as much power as I can get with an NA, too. I don't have the time or money to do a turbo swap at the moment, so I'm going to maximize the engine I am building. That said, I plan on getting a RX-7 shell in a few years and swapping in a 13B-RE. Its not that I'm against boost, I just want to maximize my NA setup before moving on.
