Just like the title says, I'm pumped and in a week or so, it should be headed my way!!! I might even make it to a dyno day down in SLC on the 18th, and possibly have some numbers, hopefully "after", but with my recent work schedule, it might have to be "before" numbers.

CarHopper

You should do before numbers anyway. Then compare to the afters

kjkidd21

100% agreed. Heck I'm doing ROW air boxes, 2nd cat delete & EC tune and even I am doing before and after numbers. Paying that much money, I think you'd be crazy not to...

I need to go back and get a dyno after my row box install, but i'm not really expecting much so I havent done it.

BLKROKT

Jelly... good luck and let us know how it goes. Are you doing the install yourself? Post up a DIY if you do!

Mort

I am a little jelly too and looking forward to your results and impressions.

AMG6.3

Congrats! Let the dyno number guessing game begin. I will start with 575 rwhp.

Are you doing forged internals or just leaving them stock?

mr747

I say 680rwhp good luck mate your gonna love it

kjkidd21

680 RWHP would be north of 800 HP at the crank.

I would say that somewhere in the neighborhood of 530-540 RWHP would be reasonably attainable. But it also depends on the dyno too.

average joe

Mine is stage 2 and 605rwhp so 680 is very attainable

Merc63

You should be well over 600rwhp.

Get ready for the biggest wow factor you can do to these cars. Putting a stage 3 on them is like strapping an acme rocket on, night and day difference. The amount of torque produced throws you back in the chair at 2500rpm.

These cars are very very fast with this mod and there will not be much that will touch you after, even sport bikes, unless it's a 1000cc.

I'm not too worried about before/after numbers, not even so much "after" numbers either. As long as she gets nicely improved track times, and I can easily beat out my buddies GTS viper that has been a really close match with for quite a while now, I'll be fine. Oh and people around here already know it runs pretty well the way it sits now, hahaha!




I actually already have "before" numbers from the local dyno that's very stingy compared to the one I'm going to in slc, but it really doesn't matter a whole lot to me, as long as it performs well for the way I use it.

skaarlaj

What are you boosted guys doing for a boost guage? I was planning on just hooking up a temporary guage, and just "checking" once in a while.


I also don't know what to expect for boost either, I live at 6500' elevation, so I know I'll be a little shy on boost, and power, but that's ok as the guy at the traffic light is also breathing the same thin air. I had an 04 Cobra that made around 12-13psi, I sold it to a guy in Texas, and he said it made almost 19psi when he received it!!

skaarlaj

Stock.

skaarlaj

I'm installing the kit myself, just a detailed write-up on how it went? I can certainly do that.

skaarlaj

I might see if I can swap the air-boxes from stock to the rows to see if there's really any real restriction in the US air intake system as I'm very skeptical, and the row setup is quite pricey for what it is. So maybe some Row airboxes for sale here if they do nothing on my combination after checked on the dyno.


I know a supercharged engine needs a lot of air, but I really can't wrap my head around the stock intake system being much of a restriction.

kjkidd21

I should have done some homework before I posted my original guess. By the looks of it, 600-650 WHP should be attainable. Congrats on the purchase!

Merc63

The row boxes are mandatory with stage 3 I thought for tuning purposes...

You will be down boost probably around 7-8psi. I have a boost gauge mounted under the hood, there is a port on blower intake manifold.

mr747

550 to 600 is achievable with a stage 2 maybe a little more 680 to 750 with a stage 3

skaarlaj

I'll have it connected to the dyno's a/f ratio system and have them shut me down if it goes out of whack when trying them, if it's a quick/easy swap from stock to the rows I'll try it.

MaroonC63

Yum. Enjoy the beast in good health.

CarHopper

What are you doing about the tranny? Just rolling the dice?

Merc63

Hey has the MCT tranny which can take more of a beating, might be fine for a bit.

Kriston

Congrats on the purchase!


The C63 with a SC is a whole new animal. I was fortunate to drive a Stage 3 here in Toronto and that car was ridiculous. Got to 200 real quick


As for the transmission, that's a toss up. I would swap out the transmission at the same time, would hate to be beating on that bad boy only to break the transmission on the freeway.
