Get cammed.

I was lookin at HKS vs Nismo R-tune cams, does anyone here have either of the two?

[BlackSmoke]

I dont know much on NISMO or HKS cams but I do know a friend of mine has a Honda engine with the Crower cams and he said he liked them, I would assume you could not go wrong with the R-Tune set up. I will side with mezz on this FTMFW.

Soup, what is you goal hp wise, that you are trying to achieve when your project is done.

[dasoupdude]

Myeh, for the bc i'd have to get the bc spring and retainers too.

You see surprised Sir Black of smoketh...did you not visit my "new pics of TT kit which came in" thread..??

[BlackSmoke]

Yes I saw it the day you put it up but I have also been noticing some other goodies you have been talking about I am just waiting to see what this beast turns out like.

Oh werd, lol and as added surprise i said quietly in a random post that, that kit wasn't even for me hahaI planned on the aps or hks s/c and that is what i am stickin too. (as a reference that sheet posted above was from the aps site from the 350z's extreme kit pull)

As far as we're concerned the chances of you getting an F/I kit as well are just as the same as mine.

[BlackSmoke]

awe you bastard you had me thinking you were slapping that TT in their. But supercharging sounds like fire in there and if that is what APS can pull on the dyno I think you should go with that, unless you messing with my blood pressure med again.

[dasoupdude]

Actually the extreme kit has a 1,000 hp potential.

[Beancooker]

Actually the extreme kit has a 1,000 hp potential.

Not on stock internals it doesn't... or at least not for more than a few days.

[dasoupdude]

But of course,

minutes* lol

how much is our Z's pushing on the wheels stock? the HR models.heard the 03's n other first Z's only push like 225hp at the wheel stock cuz its so heavy n stuff. would HR b significantly more? anybody know?

[JETPILOT]

For turbo's you shouldn't run a naturally aspirated cam profile. There are specific cams for turbo applications that have a low overlap.

I run the GT Motorsports stage 1 turbo cams and they really fatten up the midrange and make power up til 6700 RPM and this is not a revup motor. No matter which cams you go with you will need to change the springs and retainers to rev higher or you will float a valve.

how much is our Z's pushing on the wheels stock? the HR models.heard the 03's n other first Z's only push like 225hp at the wheel stock cuz its so heavy n stuff. would HR b significantly more? anybody know?

First off, the de engine on 2003-2005 non rev-up pushes 287hp @ 6300rpm (crank) and 276lb/ft @4800 rpm (crank). That translates to 249 hp @ 6300 rpm (wheel) and 240 lb-ft @ 4800 rpm (wheel). Second, the weight of of all z's vary by trim/year, which has, by the way, nothing to do with the car's whp. Now for the hr's: they put out about 306hp @6800 rpm (crank) and 268lb/ft torque @ 4800rpm. Take 13.2% out of that (because both versions of the z has virtually the same gearbox, driveshaft, and differential) and you get your wheel horsepower. Welcome to NICO noob!

[yelohandL]

so ur tellin me weight has nothin to do wit it?ok, well 13% das has been reduced is because friction and weight n all dat from, like u said, transmission, drive shaft n everything....why do u think it has that 13% reduction? cuz it has WEIGHT. so i believe weight HAS to do somthin with it.also its however much hp at the WHEELS, not the crank. obviously at the crank its gonna have higher hp since its jus spinning the fly wheel but if ur talkin bout hp to the wheels....than its inlcuding everything u jus mentioned and cars weight... transmission n drive shaft has weight too u kno

i mean if im wrong than sh*t whatever. u learn n u teach. i don mean to like disrespect or anything but u sound like u all dat so im jus sayin. das what i think and how i was always informed.also thanks for the 248hp at the wheels info for me

[xjmxstac]

13% is the the difference between crank hp and wheel hp, at least for the z's. Hp measure from the crank will read 13% more than if you take it from the wheels. This is because the power from the engine (flywheel hp or crank hp) is transfered to the gearbox, driveshaft, differential, and ultimately to the wheels and pavement. This reduced the final hp produced. Please read the post CAREFULLY. Dude, your car's weight has nothing to do with its horsepower trust me!

[yelohandL]

yea so why doenst weight hav to do anything?...you put the HR motor in like say...idk like for example lighter car, like a freakin civic idk, or even a gutted out 350Z, the numbers would b different. bc of the weight...i kno why the 13% is reduced, i mean i said it up there so but im jus sayin i think weight def has to do wit wheelhp. im jus sayin haha das what i think. i could b wrong but i really dont know why i would b if i am unless i see a proof or some kind haha not sayin ur totally wrong or anything. im jus arguing about the weight

[xjmxstac]

So, you're saying that if I gut my car out, with the stock engine and no mods, I will get more hp? That does not make sense The hr engine will put out 306hp stock no matter what. You can have bricks in the back of you car, it will still put out 306hp.

I think he's being twisted by something in essence of what is called the power to weight ratio.

[xjmxstac]

Now that's a whole different monster. One that is extensively referred to by many sportbike riders and avid race car drivers.

He's a little confused i think. Here, a got a link for you yelo:http://en.wikipedia.org/wiki/HorsepowerRead the entire thing and hit me back.

yea i was jus sayin, i jus wanted to point out what i thought u kno? no disrespect or anything immature like some kids do online cuz...they cant meet face to face. i havent read the link u posted up yet but ill read it n let u kno. thanks man.and what i meant about like gutted out Z was dat, lets say u gut it out. say jus for example like almost over 500lbs. then im jus asking wouldnt whp be better? im not sayin at the crank...cuz of course at the crank it will still b 306

haha thanks for takin time to reply wit manners tho, if im completely wrong ur prolly frustrated as hell right now!!! haha

yelowhandL, the only thing that affects real horsepower (whp) is the drivetrain. Your vehicle's weight has absolutely nothing to do with it. If you're getting 306hp at the crank, you'll ALWAYS get %13.2 less (for the Z) at the wheels. Again, the 13.2% is lost through your drivetrain.

no disrespect or anything immature like some kids do online cuz...they cant meet face to face.

i'm so sick of newbs sounding like they want to fight everyone. "come say that to my face punk!" blah blah blah stfu

[inline350]

now if your talking about weight the only thing that would do is shave off time if you where to do like drag byt the power is the same

[_b.jaye_]

not to confuse things, but you cant really say weight has nothing to do with numbers at the wheels if your talking about rotational mass (driveshaft, flywheel, etc.)... just saying

[dasoupdude]

Geeze why is everyone so worked up on a concept so simple, If you go and dyno your car and get the rate at what is put out to the wheels you'll get a number. If you come back the next day and still take out your seats, sound deadening, spare tire, close to E gas tank, etc etc; chances are, you'll Still get that same number and if not it would be pretty damn close.

The only difference it would make would be shaving small sections of time off during a run because it would take less power to generally move the car forward thus transferring the rest of the weight savings into forward motion.

Which brings me to my next question...who has torque dampers???

[rmezz13]

Myeh, for the bc i'd have to get the bc spring and retainers too.

You should change them anyway... get your head cleaned up, and mine as well open it up and go with bigger valves.... just completely build them, it was a plan of mine, now i'm just broke all the time for some reason... anyway it will cost around $2300-$3000 to build them with the Crower stuff and machine work and ARP head studs and Cometic gaskets.... if your planning on boosting the car, wait on the head job, if your looking for N/A power, it can be found in the heads. Don't be surprised to see 50hp added from heads but thats 50hp for roughly $3k.... Also check out greddy TT, since trust announced bankruptcy the price has went down on the greddy website ( i think) .... if i had the money....

[JETPILOT]

Greddy USA hasn't declared bankruptcy. Everything in the USA is business as usual.

I think he's being twisted by something in essence of what is called the power to weight ratio.

Correctamundo!

Horsepower is horsepower, weight of the vehicle producing it has absolutely no bearing on how much is produced. What weight does affect is the speed that the horsepower is able to propel that vehicle. A Dodge Ram PU has more horsepower than a Lotus Exige, but the Exige trumps it in performance (except cargo room I suppose) due to its supremely low weight.

Its easy to to make a light car fast, but much harder to make a fast car light(er). This is why Super GT (and FIA GT) use weight penalties (Super GT calls it "Success Ballast").
