you say that, but take a ride in it and you'll slap yourself for that comment.

 

Somehow I don't believe your sincerity. If this motor came stock in a 350Z and an aftermarket company devloped the same kit for it to produce these power levels, you would be jumping up and down.

You are not impressed, because no matter what the power output is, you degrade domestic automobiles at any chance you get. You are not a real enthusiast. You are a fanboy hater.

I, on the other hand, appreciate cars from all makes & brands. I hold no national allegience when it comes to an automobile. If it performs well, I give it credit. I don't give a crap if the company uses 10000 rubber bands to get it to move. If it performs, I appreciate it.

 

Thats just sick...Love the look and the power...Hard to hate on that...

 

I can kinda understand what you are saying but it comes off like you are a hater/fanboi like some have said.......What you are getting at is that both kits raise the hp around the same % over stock then you are right...However I think its impressive that a 350z can make 420-430rwhp with this kit considering its an open deck motor and fairly high compresion with Hi-boost unfriendly rods...So why isnt a Z06 with very high compression motor not made for boost that makes around the same % gain not as impressive???

I think that Supras and Vipers have spoiled it for other cars when it comes to stock ability to handle large doses of boost.....Import heads yawn at the 350z "only" able to handle 420-430rwhp reliably and vice versa the Domestic heads when it comes to this Z06 with "only" 600+rwhp.....Its all relative but those that understand what each motor is about will be impressed non the less even if it aint the fastest car......

Think about it...A 420-430rwhp 350z is an 11 sec car that would trap between 116-120mph...Very fast street car....Likewise this 600rwhp Z06 is a low 10 possibly high 9 street car.....Stupid fast for a streetcar.......Impressive TT kits

 

granted we all know domestic engines are not as efficient as smaller import engines, but I thought 8 psi APS and greddy TT kits did in the neighborhood of a 120-140whp improvement vs the 210whp improvement with the Z06 at 8 psi

 

Clearly you haven't read up on the LS7. I'm an import guy at heart, but these next-gen LS motors are awesome pieces of machinery. And not just because of their displacement either...

 

well the LS7 might be one of the more efficient american designs - and I'm NOT knocking it, but "domestic" engines (what I said - I never said anything about the LS7 specifically) in general seem to not be as efficient - I can ramble off a whole list of comparisons - mustang 300hp 4.6 liter V8 engine vs 300hp 350Z V6 engine, etc etc

so don't go around saying I haven't read up on the LS7
we all know its deal and what it can do with 7 liters
505 hp with 7 liters vs 300 hp with 3.5 liters VQ35....still not as efficient or it'd be 600 hp. It's not really so much a thing about american vs import engines as it is big vs small engines because big liter engines have a harder time breathing efficiently at really high rpms

 

It makes alot more than us, well......becuase it comes with over 200+hp more than we do. My first PE(Power Enterprise) kit, made 412rwhp on 8psi of boost. Thats almost a 200hp increase as well. Mind you, this is coming from two turbos, that are half the size as well as half the displacement. Im not hating on the LS7, it is a remarkable motor with plenty of potential. But I think the 350z should be compared in the same sentence, when comparing the two.

 

just curious, for 412whp, did you have to go to test pipes and a larger exhaust? Does the Z06 have to use test pipes and a larger exhaust with the APS TT setup to make it's power with 8psi?

 

That would be a smart move,
My dad has that set up-- its groossssss, tooo much power

 

I only had hks exhaust on there, with stock cats. Stock motor and everything.

 

The Mustang makes 300hp on 87 octane and a very crappy tune. I would also bet that the engine itself is less expensive to make and purchase than the VQ35.

 

Of course it is cheaper to make. Less cams, less technology involved. Still point is, it has 1.1 liters more and makes the same hp.

 

I stopped reading after the HP/Liter argument. Next.......

Furthermore, show me a large V8 motor (5.5L and up) that gets better MPG than the LS-series and I'll shut up.

 

There's WAY more to an engine than stock BHP numbers.

 

the LS_ engine's MPG is mostly a function of mild gearing
.5 ratio top gear

 

I agree 100%. Hp/liter argument is stupid. Power output vs fuel burned would be a more accurate comparison of efficiency.

 

i don't think anyone is going around here feeling cozzy about their engine being more efficient because it's smaller

smaller engines are more efficient at high rpms, that's just a fact. It's easier to fill a small chamber up with air thousands of times a minute than a big chamber. F1 race cars rev pretty high. Why don't they go with more displacement and rev lower if that's the best way?

Granted, a bigger chamber will still ultimately produce more power and be capable of supporting more power with FI etc
bigger engines will always have more low end torque than smaller ones - exluding any power adders

 

HAH!! I was just waiting until somebody mentioned this.


Tall gearing is only as good as the engine it's paired to. Due to the valve/port configuration that pushrod motors have it promotes intake charge swirl and good velocity through the ports at low engine speeds. Very efficient combustion at low RPM's. This is why honda VTEC motors stagger the valve lifts on the intake valves at low engine speeds to promote efficient low speed combustion. Yes the tall gearing helps, but it helps even more that the engine makes very good torque at those low engine speeds. Try that gearing on a VQ35 and you'll end up having to press the gas pedal so far to compensate for the fact it's not making enough of its torque down there that you'll actually see a MPG loss.

 

F1 cars have small displacement motors because the rules state they have to. Has nothing to do with choice. If they could go bigger, they would.
