Can you get to 400 without turbo or super-charger

JoeyD

^Yes, I really do. Stillen has been around for a long time, they have no reason to fudge numbers or out right lie, they service a niche market. My point was merely that 350 Crank HP was an absurdly low estimate for the mods listed, it would be a gain of only 18HP for I/H/E. Also, I would be weary of drawing parallels from the 35DE/HR to the 37VHR they act completely different regarding mods, as you yourself said. I'll stick by what I said earlier in this thread.

-CAI
-Header Back Exhaust
-Injectors
-Ignition (like the HKS DLI)
-Pulleys
-Aggressive Tune

Should Yield over 400 Crank or Near 350RWHP

Are you insane? You think you're going to pick up about 70HP to the wheels on intake and a header back? Keep dreaming my man.

-First, injectors - why? What for? You cant tell me the stockers are being pushed that far to their limit.
-Ignition - why? The stock system should work just fine with those mods as they are minimal.
-Pulleys - going to be MINIMAL gain seen from these.

This isnt Need for Speed: Underground here, dude. I bet people will be lucky to get maybe 310-320 to the wheels with a TOP QUALITY I/H/E setup and tune. Either way, you'll just be disappointed if you want to play the numbers game on this car, and drag it to a Mustang Dyno...which is where you should rightfully go for a tune, anyway.

Son...On a mustang dyno, Final Dyno Numbers - MY350Z.COM Forums

~350whp...On a mustang dyno with I/H/E and a reflash...VQ37VHR. From ~260whp bone stock to ~350whp with room to make a more aggressive map. That's ~90whp from 3 mods. Hard to believe but the proof is there.

How many times do I have to post that link? Is something wrong with the dyno? Are the numbers off?

Your posts are about as abrasive as they are wrong. Thanks dude, I can tell the difference between reality and video games. People like you are what is wrong with the forums, you come on here and play the Internet tough guy, but I guarantee you you won't talk like that to me, or anyone else, when we are standing right in front of you. I doubt if you have read any of the findings from G37s (which is a much better comparison than the 350Z) but they support my estimations fairly closely.

Apparently you can't tell the difference from one engine to another. If you knew anything about cars you would also know that hotter spark (ignition) will yield power even without any supporting mods. It results in a better more efficient burn. Pulleys may be a small gain, but that's how you make power slowly through an intelligent selection of upgrades. Injectors are for good measure, the other mods will result in a leaned AF ratio; better injectors provide a margin of safety rather than your assumption of it. Anyway, I said 400 Crank HP in both posts. 400 Crank with a 22% drive-train loss is right in the 330-340 RWHP neighborhood. So, it would appear to me you have no idea how Crank and RW horsepower interrelate. Maybe you should read more and post less.

Just giving you a little dose of reality. I'm sorry you're getting so hurt over them. If you think I wont call you out in person, go ahead and try it. Ive heard BS responses to power claims, 1/4th times, and mods done plenty of times. Ive called them out everytime. But I prefer to do it in an intelligent way, rather than simply call the person a moron or a liar to their face.

Sorry, but I HAD a car that put down these numbers, and more, on a Mustang Dyno. I know what it takes to reach these power levels. I/H/E + tune wont do it. I'm sorry, but this is real life. Go out and do it yourself if you think you can actually do it.

The other mods will result in a leaned AF-ratio - but, hey, he got it tuned - so wheres the problem? Once again, I ask, are the injectors THAT strained? As far as not understanding RWHP versus Crank, who cares about crank HP? I was talking WHP the whole time.

You go right ahead and read "reported" dyno gains and assume everything just keeps adding up so simply, that you're going to pick up 70HP at the crank with basic mods. Sure, 400 crank translates to 340-350 WHP...on a Dynojet dyno, maybe. NOT a Mustang Dyno.

You know what, I dont even know why I mention all this stuff in here - why do we even say anything RCZ? Lets let the bench-racers get their mods, spend the cash, and just be disappointed. Let them go to the dyno, get a tune, and come back with their heads hanging low wondering, "why oh why, did I not get 350 WHP on a Mustang dyno? THE PEOPLE ON THE MESSAGE BOARD SAID THEY DID IT! IT MUST BE TRUE!"
