Potentially a New C63 owner, Question on NA limits


I understand that long tube CATLESS headers, with a ECU tune and the ROW air boxes Will yield between 480-500 WHP depending on octane, dyno type or testing conditions.
I also understand that the underdrive pulley can yield another 10 or 15 wheel horsepower based on what other members have shown at the dyno.

So my question is what if you added a snow performance methanol injection system, ran a 95 or 100 octane tune with it and did the underdrive pulley? My calculation is that you should at least be able to reach 520-540 WHP
what do you guys think?
Also if someone knows the maximum amount of power that the MCT seven speed can handle it would be great to know?
Headers + tune 460- 480whp tops
Underdrive crank pulley inconclusive, but I wouldn't give it credit for much more than 5-10hp
The jury is still out on whether the new EC V7 tune actually delivers, but if it does, then 500whp is hopefully attainable with just headers
At a guess, with meth, you'd be looking at 520 and even then that's with a bespoke tune with timing in the low 30's up top
E85 kits/tunes are available and will see you over 500 with headers
I don't know the torque limit of the MCT but I'm sure one of the 'charged members will be along soon to let you know - needless to say, you won't get anywhere near the limits while NA
you dont see people around here talking about meth injection probably because the gains on this n/a platform are minimal at best. I have a good amount of experience with the snow kit on my former boosted acura tl and with forced induction its a different game.
Just stick with what has been proven to work on this almost 10 year old platform

Are you actually looking for opinions, or just someone who agrees with you?












You're a classic case of a keyboard warrior who probably can't even string together a sentence in real life.

Additionally, your understanding on mods is a little off. You can't simply add up what each mod gains individually. Example: if an intake says it will gain 10 whp and an exhaust says it will gain 20 whp, you don't usually get 30 whp with both. You might 22 whp with both mods or maybe 25. Hell, they may not even play nice and you might get 15 whp or even lose power. Bottom line (as stated above): headers, ROW boxes and a (off the shelf) tune will get you 460-480 whp. Underdrive pulley probably gives about as many gains as taking a dump before your next pass.

theres the underive pulley since u brought it up.
I no what all these mods make according to members on here, my question was what would the whole thing together possibly make.

So either you're just trolling, or you're looking for someone to come in and support your dumb ideas. Your answers don't indicate someone who is looking for opinions. Go search for meth and see how many people have used it in the 10yrs this platform has been out. What's relevant in the smaller displacement forced induction world rarely holds true for this platform which is the polar opposite.
But whatever dude, if you're so sure have at it man and let us know how it turns out.
