To get to 400rwhp you may need to do the above + a 3.8L conversion. A few of them has been done here in Taiwan with factory parts I believe(C350 heads + E55 pistons if I remember correctly).

in Eurotuner or some magazine like that, they had a Dyno shootout. One of the participants was a Evosport C32. It made 420rwhp. Evosport was supposed to release a stg 3 kit but decided not to cause it was too expensive.

Speaking of nitrous, i have read places that sometimes, nitrous can mess up the inside of the s/c (like the lining or something). i do know that people spray with s/cs, but it could be because they are different s/cs and may have a special coating or lining. does anyone know the strength of our s/c coating/lining and if nitrous would mess it up?

Ah, that's right. I forgot that you ported too. Why don't you share a dyno sheet?

I'm keeping my fingers crossed, but I'm quite certain there will be a HP increase after these are finally installed. I saw the catalytic mid-pipe for a C230K at the dealer and it had huge 3" piping.

I was an inch away from cams and head porting, but was delayed because my Evo Stage II got delayed...
pshek, I would love to see your dyno results though before I hit the trigger on this...

I was going to give the car to Evosport, and I think they sub-contracted to a specialized shop (sorry, don't know who they actually deal with?)
Are you thinking about Cams and heads too?

I was thinking about Schrick Cams since they are about $800 cheaper than Kleemann's...

What kind of dyno are you going to be using?
I'm going to dyno before I install the 2.5" exhaust, ASP pullies, and green filters, then I'll do an after dyno with the mods. My car is currently around 300rwhp with the smaller 1.80" exhaust. I know for certain that my C320 exhaust pipes are less than 2" diameter and C32 stock pipes are around 2.5". I could almost wrap my whole hand around the C320 pipes. I'm keeping my fingers crossed, but I'm quite certain there will be a HP increase after these are finally installed.
I saw the catalytic mid-pipe for a C230K at the dealer and it had huge 3" piping.

The rolling dyno gives a more accurate real world reading of rear wheel HP..
You say you are only making about 300rwhp now? what is your estimate after your above described work?
Thanks

HOP has a dynojet, which is what I'll be using. 300rwhp is a conservative figure.
BTW, Josh is porting the heads on my old C320 motor, which shares the same casting as all the other M112 motors. Hehe....I wonder what he's going to do with the old motor? Should be fun.

Depends on if the engine is going to be boosted or normally aspirated. On my old normally aspirated 320 motor, the valves are about 1mm bigger. We did not go with bigger valves on my low compression AMG motor.

i will upgrade it if i go with cams, just to be on the safe side...the motor may be low compression, but with a F/I motor it raises the effective compression...
