350 whp BAD!!!!!!

Umm...what is the OP smoking? :)

I just hit the 400whp mark in my Speed3. Yes, you HAVE to and should re-enforce everything including studs. If you want to make that power, everything needs to be changed to be safe...better safe than sorry. At that power things get very hot very very fast. Especially when you start swapping turbo's and internals and the like. But there is NO WAY the motor should not be able to hold that kind of power. People are running all day on 300-350whp.

Just keep an eagles eye on your oil gauge and temerature gauge and you will be fine.

I think the OP is referring to the rods... Stock rods will most likely break at around 350 WHP!! This is the weak link in the MZR engine.
 
There is no way that anyone can make a blanket statement like "your rods will go if you have 350whp". How do you explain people making much more than that on the stock block and doing 30-50 drag strip passes/week?

there are no if-then statements when it comes to power capacity.

Also, what does 350whp really mean? It means that you found a dyno that spits out 350 when you do a pull. Then you take it to another dyno or shop and it spits out 320 or 360. You can calibrate a dyno to read any number you want.

I think at this point with the development of the MS3 you would want to consider building your motor if you plan on adding 150+ whp over stock which for most cars is around 350whp on an average dyno. Once some 'real' tuning is available for the car, this number may go up though.

I get customers that ask me questions like these all the time like, 'will my transmission fail if I do X mod?' or 'will my motor blow at Y boost'? The answer is that there is no way to tell, there are a thousand variables that go into EACH one of those issues. The best we can do is come up with a basic rule of thumb but even then, nothing is written in stone. The absolute bottom line is that if you modify your car, anything can happen.

Very Well Said,, you Pay to Play, and once you modify your car you are running the risk of breaking anything. nobody can guarantee you is not going to blow up.. but every car is a different story and every car holds more power and are faster than the others..

That is what i thought. If Someone ran stock internals. how much and what goes away first. Rod bearings? I also was thinking of a professional tune focused on our car. and of course going to the root cause of the failure. I am not even aware of any 2.3s that rev to lets say 7200. You guys have great points all of you. Maybe more and more detailed info will surface after time. Thanks. and in regards to smoking rods, just say no
 
I actually think TQ would kill our motors first before HP since HP is just a calculated number not an actual force. I still think im highest tQ number to date and my motors still hanging around.

Yep i sure would like the performance you are making D and glad you still support us newer folks.
 
better save up for a turbo upg, if the block from my buddys totaled car is still good im take that and build it so when its done i can just swap it in but we'll c
 
^^^^thats until my intercooler get here lol jk

Dre do me a favor get a pump. Back when I put down 303 I couldn't get my car to trap higher then 107. It just didn't make sense. I finally listend to loosh and got a pump since he kept nagging me and my car is a totally different animal. I honestly don't think i really need a top mount either with the meth my boosted temps stay at 98. I might just get it for the pressure drop to make my turbo work less.

im saving up sir i wanna get it just to play it safe just really hard to push out 600 bones
 
if done right, the stock engine holds more than you think\/\/\/\/\/\/
You mean, more than i hoped. You fella's are making lots of progress into nasty power land. I hope I can run nearly that much when all you serious folks nail it down. Thanks soo much for pushing this car further and further with performance. It is nice to know that even if my Mazdaspeed 3 is, will not be a track monster, i know of some speed 3's that are. keep it up please. I do appreciate the trickle down effect on performance parts and tuning and even more the sharing with us little speedsters.
