Hey guys i have a 01 cobra with a kennebell supercharger. I'm wondering what the stock engine can handle as far as power. Right now i'm at 489 at the rear wheels. Any input is appreciated, thanks.
Max power for 01 engine?

crap shoot for sure at that point.........a good tune can make all the dif...and you must have a good one, since your still in one piece
Thanks guys, I have a great tune from a local shop that specializes in mustangs. Hopefully my good luck lasts awhile...
Not trying to thread jack but how different is the bottom end of the 01 Cobra 4.6 from the 01-04 GT bottom end? Are they similar short blocks with different heads? I figured the question would help with the topic of the thread.
I'm pretty sure the GT blocks are iron while the Cobra blocks are aluminum. The GT cranks are cast and the Cobra cranks are forged. The rods might be the same. I would imagine the pistons are different to make up the difference in combustion chamber sizes between the 2v and 4v.

crt?
he tunes alot of mustangs in the 450rwhp range and they hold together for a good amount of time.
Couldn't he just upgrade the rods and pistons and not worry about anything?:shrug:
He could. But maybe he can't afford the down time. And it's not just rods and pistons. There's also gaskets that should be replaced. And the TTY bolts then need to be replaced when the motor is taken apart.
Also machining may be needed. Sometimes the crankshaft needs to be turned and thus the bearing need resizing from the stock size.
IIRC stock internals are rated around 450hp ast the crank becuase of piston and rod strength. at least that is what i have seen in my research so far. i'd like to get mine to ~400rwhp and call it done, but i think that's put me close to 470hp or so, so im not sure what to do for next power mod yet.
what shop?
Shop is called dayton performance. They have tuned a couple of my friends cobras and have done an amazing job with all of them. I've looked at some of the kits to upgrade the rods and pistons, just a lil short on cash right now.
I know them well. I figured it was either Precision Autosports or Dayton Performance (who used to be Dayton 5.0)
Damn, I would not go any higher than what you are now.
Honestly, I would turn it down some. That's why I stayed in the 430rwhp range. These motors are known to
op: around the 450rwhp mark.
How long have you been running that setup? Did you do an eaton swap or the 99/01 KB?

I've been running it like this since last july. Only put about 4-500 miles on it a year. Dont push it to hard either. Its got the 99/01 KB intercooled kit on it, running about 11 pounds of boost.
tick tock, tick tock, tick tock
been there. done that. turn it back or get ready for a rebuild.

wow 489 out the KB..is it a 2.1?
i've been running my 1.7 ICO 01 at 468RWHP since 2004...thats 33K miles ago, and it sees boost every time i drive it
it's all about the TUNE...just know that you are at/beyond the limit, it's a timebomb really lol
OP how much boost are you at?
i've been at 9.5 indicated (11psi pulley) since 04

4-500 miles a year and you dont push it? Lower the boost to lesson the chances of an explosion because 500 miles a year isnt worth the investment of a new motor IMO
