I haven't been on the g37 forums so I personally don't know but I don't trust that 90 horsepower gain. They were most likely taken on different days considering that headers were installed. That brings up a ton of variables between the 2 dyno runs.

~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? Last edited by KingDavid; 03-13-2009 at 05:25 AM. |

Not insulting your intelligence or anything but don't be ignorant about what you see. Be proactive and ask questions. Join that site and ask the user whatever you need to know. On a side note, that tune was backed off as well. The tuner didn't want to push it so there's room for more. |

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.

90WHP out of an N/A 3.7L like the one on the 370Z is impossible on an exhaust, intake and tune. You are not going to point me to one stupid thread because I will point you to 6,000 other ones that say your numbers are bs. If the motor is turbo, like an EVO or STI, then yeah you can do that, but not without compromising reliability. Quote:
Find me some more threads that claim 90RWHP gains with a stage 2 car. Please. Really, I want to believe it! Quote:
Listen guys, you are arguing over something that has no real basis. As much as I would love this to be true..it does not make sense. The parts that were chosen aren't even full-race no-compromise parts and the tune is "backed off." Clearly by reading your rationalization of the mods, I can tell you have the theory down JoeyD, but you need to be a little more skeptic about the results that people post up on the internet. This is the same subject over and over and over again... I would be very very very happy with a 40RWHP(30RWHP on a mustang) gain on a stage 2 setup, with a very aggressive tune. That might even be fantasy too though... But hey, in due time we will see which one of us is right, so there's no point on arguing about theory right now. I dynoed baseline at 256whp. If I get an exhaust, intake an a tune and I come back with 346WHP, then I will gladly take back everything I said. Until then, I'm going to get my feet back on the ground and hope for 290-300whp. |

Are you aware at all of the difference between a pre-mapped car vs a custom tuned one? At all? A walk on the other side of the world but K-series motors make a considerable amount power from a pre-mapped K-Pro vs. A tuned K-Pro. And since you're questioning the integrity (or validity) of respected members info on that site, I'll see if I can drag them over here for you. Maybe even get a video of a dyno run? We'll see. |

2)Stage 2 on cars isn't a name given by tuners to a map or kit, stage 2 is widely understood to mean intakes, exhaust and a tune. 3) I don't need to ask anything, I know the bs answers already. Not to mention that if the guy is clueless enough to post a 90RWHP gain with those mods, then chances are he doesn't know his *** from his head about tuning. 4) You are asking me if I know the difference between a shelf tune and a tune? give me a break. I had over 40 hours of dyno tune time logged on my 04 STI alone. Also you call this a "re-TUNED reflash" do you even know what that means? I've had dinner with Trey Cobb, nice guy. 5) I don't give two flying bleeps who that guy is or how respected he is. 6) A video of the run lol, what is that going to do? I can have my tuner adjust the dyno and then video tape a run on it and make 400RWHP on my untuned intakes; what does that prove? I will believe it when I see an independent dyno with a stock VQ37 doing a pull and setting a base line and then he can do a pull right after. I want to see that 90WHP gain. I can't see the graph, what's the AFR on it? Race fuel? not that it matters.. 7) Don't bother, we don't need that kind of nonsense here. Listen, you are telling me this guy threw on an intake, an exhaust and a "re-TUNED reflash" and gained..lets see...a 35% gain of power over stock? Don't you at all think there is something wrong with that? Like at all??? You are in for a rough brush with reality... Last edited by RCZ; 03-13-2009 at 09:47 PM. |

Also RCZ i do agree with u that on a car like this ignition mods are useless but a underdrive crank pulley actually helps. I picked up about 7whp from my 350 with it so it does add up. |

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!" Last edited by MightyBobo; 03-14-2009 at 03:31 PM. |

Anytime man. I dunno if there is a difference betweeen an underdrive crank pulley and a light weight one like the one stillen offers. Maybe one and the same thing .
