Can you get to 400 without turbo or super-charger

Find me some more threads that claim 90RWHP gains with a stage 2 car. Please. Really, I want to believe it!

Tune was backed off, wait...so this is a conservative tune that made 90WHP? Oh dear.

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.

Lol, As they come I will. But there's no stage anything. It's a re-TUNED reflash. The maps from COBB aren't on there. But again, ask the guy and the tuner himself. If the proof is there and you question it, ask questions. Don't be so quick to be so skeptical. Just ask. All of those dynos in that other thread are all pre-mapped and untuned. All of them. But if more pop up then so be it. If not, oh well. But it's intake HEADERS and exhaust and a TUNED reflash. So get it and tell us the results. If it's wong, then hey it's wrong, but if it's not then hey, learned something new.

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.

1) The headers are part of the exhaust, hence the term exhaust covers it all.

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...

+200. Agreed with everything you said. King David..it doesnt matter how many times u post that link. Thats only one dyno of a 370 making 350whp. Now like i said before, if i see more independent dyno runs then ill be a believer. Till then im taking that graph with a grain of salt. If u really knew anything about tuning, u would know there is no way u can squeeze 90whp from any VQ with just and intake/full exhaust/and a tune regardless of how good the tune is. Thats why i said in my previous post i would expect around 300-330whp from a dynojet with a setup like that depending on variables.

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.

Big cube motors like a 8.4Ltr Viper or 7Ltr Z06 wont gain 90-100rwhp from i/e/h and tune but a 3.7ltr 370z will? Sadly Im out of the game now but if someone can prove beyond a shadow of a doubt that the 3.7ltr 370z can indeed make 90rwhp that easily I may have to ignore the economy and my own finances and get one at all cost.

Easy way for him to find out if that g37 is making 345rwhp. Hit the 1/4 track and tell us what your trap speed is. Im not the most knowledgable guy here but in the years of me spending at the drags Ive learned the 1/4 mile exposes bs dyno numbers from my experience. I remember a guy that supposedly made 445rwhp on a stock engined DE. I never believed him then I saw him run at the track and his best run he could only muster 113mph flat out lol. He should be easily pulling 118-122mph and on a really good run around 124mph all things being equal or at least in the 118 range consistantly. The dyno said 445rwhp but the 1/4 said NO WAY BUDDY. Dynos are for tuning and 1/4 mile is for proving Ive always said.

I believe phimosis did it.

Blue line: Stillen parts + Technosquare ECU reflash + dyno time.

In summary: $3,200 in Stillen parts gave a 26 hp increase over stock to bring it up to 328 compared to the original 302.

$700 for ECU reflash and dyno time ($500 for reflash only) gave an extra 15 whp for a total of 343 whp.

In total, it was nearly $5,000 including installation of the parts to gain 40 whp over stock. The throttle response in now extremely precise. The sound is wonderful, the over-rev to 8100 rpm is phenominal. The "Buzzy" engine vibrations that car magazines have been talking about are no worse above 7500 rpm. If anything, it smooths out a little.

One last thought: Lets pretend I gained 2 hp from removing the stock rear exhaust section. This car would have made 300 hp in this dyno. If the stock engine was 332 crank hp and it made 300 hp on this dyno, that's a conversion factor of 1.1066 for frictional loss (332/300). After mods, this car is making 343 hp on this dyno, which would be roughly 380 hp at the crank (343 x 1.1066). Not bad.

Ehhh, you're right, if it were true a lot more would have happened. Not to mention that this was supposedly in December.

Please keep the discussions going "without" any attacks or name calling. Everyone has an opinion and they can express it since it's a public forum. YOU also have the right to disagree with that opinion. Just explain why you disagree with it in a civilized manner with your constructive post WITHOUT any flaming . I am sure they will appreciate your post and knowledge. Thanks.
