Don't hate the players, hate the game!

 

carefull L4rry_B1rd & kungpaosamuraii, R2D2 will PM you a message from Princess Leia.

 

put more fuel and air in it
muhahaha lol

 

No one was asking u & ur gang of Teddy bear mobiles...

If u got issue with me teammightyminiz keep it in PM and keep this forum on the topic. Ur sarcasm isn't welcomed here.

 

in car adjustable gearbox? no wayyyy thats just crazy talk, for what im talkin about u have to take the whole unit out everytime you want to make changes, but i think the gear kit sets are more common
but im not sure but i think i heard something once were that infinity fx suv has some kind of continueously changing gearbox were its constantly changing ratios to be in the most efficent point at all times, but im not sure on that

 

Ok so to get back on topic. On a N/A TC the fuel rails will not be needing any type of upgrade correct or did I misunderstand that? Also Anyone know of a place we can get a better fuel pump? Im trying to upgrade my fuel system so I can get more power. So far I got Weapon R Short ram,Megan Racing header(catless),CC s-pipe,injen exhaust, Greddy E-manage. I want to go with a better fuel system before I go higher compression. The compression on our TC right now is 9.6:1 correct? Any who atm Im running a lean conidition which I will correct once I have a better fuel system via the greddy e-manage. Also anyone know of a company that makes custom high compression pistons for our cars?

 

zpi i think will start makin internal engine parts for our cars as soon as their engine blows up so they can take it apart and make new parts

 

Its called a CVT... Continuously Variable Transmission. It uses two pulleys connected by a belt, the pulleys change diameter based on load and RPM. The changing diameters change the gear reduction. The nice thing is that a CVT never "shifts" so power transmission is always nice and smooth.

 

... I just someone hurries up and makes an intake manifold already

 

YEah! thats exactly what i was talking about, why wouldnt something like that work for racing?

 

[quote="sensay"][quote="Dieseler"]Off the top of my head, I would say belt slippage.... I know the new Hybrid Highlander uses a CVT, but there aren't too many other cars yet that use them yet. My experiance with them is on smaller engines and they work great for the applications, but we replace the belts fairly often. Then again, our belts are exposed to all sorts of nasty environments.

 

thats why I asked, I was like an in car adjustable gearbox! This guy is crazy. As for CVT in race cars, it doesn't really lend itself to high stress arenas like that. For a daily driver that isn't a sports car it works fine. Plus you don't get any engine breaking when you down shift because, well you can't down shift!

 

I've never had an engine break because of downshifting! However, engine BRAKING during coasting does still occur with a CVT but it is a bit different in feel and response....

The weirdest hurdle to get over ( for the driver) with a CVT is that engine RPM does not change near as much since the gear ratios are changing instead!

 

We have a CVT and it just doesn't perform as well as a manual transmission.

We've seen the Porsches with their versions of CVT and they perform beautifully. The technology is getting better and we'll be seeing more CVT type transmissions entering our market.

I believe Mitsu has a new CVT/paddle shift 4 door... Evo "TYPE" coming ashore soon.

Dieseler : Great Point. I agree about that weird hurdle.. many of us are used to watching rpm's for shift points and saftey curves. The CVT has all that minded internally so we can concentrate on the road.


Droid: Who was being sarcastic?

 

What does the transmission have to do with making power? Sure, a better set of ratios will help, but all a transmission does is multiply torque. If you don't have the power to being with, it's a wasted effort. I thought the thread was about "all motor?"

CVTs have been through many iterations over the last 75 years or so, but so far, no one has produced and economical CVT that would handle any serious amount of torque (and yes, just like clutches, a gearbox designer only cares about input torque).

 

I remember when we dropped a GM 400 Transmission into the belly of a '74 Nova.
Transmissions are logical power upgrades.

 

Really? How did it change the engine's ability produce power?

 

it changed the gearing or drivetrain loss i'm guessing

not anymore power to the crank but less power lost between the crank and the wheels.

note to TeamMightyMiniz : he isn't talking about "creating" more power between the crank and the wheels..

 

im in the process of doing all motor...right know i have header,intake,full exhaust system, ordered pulley,grounding kit, over the winter i was thinkin gof boring it out then i would change the pistons and the whole 9 yrds but i think it will bring me up a little bit,,,act cltuch stage 2 street/race with the hks light weight flywheel...the clutch and flywheel upgrade will help with the gear ratio and it will grab the gears alot faster and harder...does anyone have any other advise other than what i plan on doing.....

 

The 2AZ can't be bored (well I shouldn't say can't but it'd be a be-otch). Just get higher compression pistons (10.5:1 or 11:1), stronger rods, polished and balanced crankshaft. You could de-stroke the motor to give you more displacement and raise your redline but that will sacrifice some of that low-end torque you've come to love. P&P the head, larger injectors, hi-flow fuel pump, etc, etc. Hope you got $$$$ since a lot of this will be custom since most of these parts aren't available......yet.
