funny how you guys are worring that the MT will not be released or something in America...I was afraid that the AT won't be released =P In my true opinion though the chances are both will come out almost to 95% in my head.

Also i've never seen a evo 7 gt-a without the hood vents does anyone have some pics for that?

 

Who told you 91 was going to be the US standard? That isn't true.

 

Wow, so much mis-information here... A few things of note:

- Driveline loss for an AWD car is still up in the air. However, most would agree that it is in the ballpark of 25-30%. Trust me, I drive one.

- I highly doubt that the EVO VII will come over here with 315hp. Once the US gets done putting catalytic converters (not to mention other ODBII systems), the hp won't be anything like it could be. Of course, most of those devices/systems can be removed (For example, my 3000GT VR-4 has 3 catalytic...well, HAD 3 catalytic converters - the cats hurt turbo spool time and top end breathability.) It also had an EGR system that was promptly blocked off.

- I keep seeing horsepower numbers thrown around and this relates back to my first two points: Mitsu is quoting horsepower at the crank/engine. However, you really care about the horsepower at the wheels (known as rwhp, fwhp, or awhp). Horsepower at the wheels is what matters since it takes into account driveline loss.

- As for upping the boost/modding the car, that will depend on a few factors such as:
*fuel injector size?
*fuel pump size?
*how many cats/restrictions are on the car?
*how big will the intercooler be and where will it be located?
*will the tranny hold the new power?
*what changes have been made to the 4g63 engine (if any) and can we use the knowledge from the DSMs to help us?
*what size turbo will be in the car and will it hold boost til redline?
*will the ECU properly retard timing when it sees knock?

There are so many factors that go into a turbo car when you are trying to make it fast.

 

Ruiner,

Dont forget you are in the rumors forum.

 

Hey guys... look who came back from the dead?

 

It is true. I just read it in the newest CHP(Chevy High Performance). It's been Federally mandated to reformulate gasoline with Methanol and Ethanol to lower emissions. Cali. was first (and most noticed) because CA. also passed a law banning service stations from using an additive called MTBE which is polluting our water. I don't know of any other states doing that,(MTBE removal), but I know federal regulations are requiring reformulated gas. The reformulated gas has an octane rating of 91. Sad but true.


ps: Start buying stock in companies that produce octane boost

 

No... start buying commodity stocks (in corn). Why? Because of the new regulation to put Methonal into gas. It is a ploy to keep the corn farmers stay in business.

Critics have said that it might use more fuel to produce the corn/methnol than saving the environment.

 

Ethanol blended gas is ***! I accidently filled my car up with it and it burned through my tank in half the time it normally does! In about a half hour drive on highway I burned through 1/4 of a tank! That would normally last me 1 1/2 hrs highway. Fight this to the death! Move to Canada, do whatever it takes!

ethanol based gas (E-85) isnt bad. I work for a project building an SUV based off this gas and know a bit about it. if the engine is designed for e-85, you can get at least 25% more mileage, and almost no grenhouse gasses as well as lower emmissions across the board. The sayign that it takes more gas to produce it that otherwise refers to all the farm equipment used to plow/grow/harvest corn and such.. but this is used anyways to grow corn to eat, think of it as killing 2 birds w/ one stone. (ethanol requires the kernel of grain but many other useful parts are left of the grain). plus if farm machinery is switched over to e-85, it wouldnt really be a problem now would it?
True, the potential thermal energy of e-85 is slightly less than regular gas ( 15-20% off the top of my head), so you would need a bigger tank to have the same range (in a non-specialized engine), e-85 has the potential to be way cheaper than gas in the long run(right now its as expensive as gas), as its renewable (comes from grain, not oil) and it wouldnt have to be imported (US imports like 60% of its oil). plus converting an engine isnt really too hard, just a matter of swapping fuel injectors, fuel pump, and other minor things.

 

We're talking about winter blend type ethanol gas...it SUCKS Hard core. :

true, one of the drawbacks of ethanol is that its bad in cold weather. it doesnt fare well in a cold engine, and it needs additives of regular gas and other stuff so a really cold engine will even start, but it makes performance suffer.

 

The dyno power for the EVO 7 in japan is around 305-310. All the good sports cars in Japan are listed at 280hp because they have a gentlemen's agreement with the government that they will not make cars over 280hp. But of course they all went over the limit. The supra makes 320hp - listed at 280hp. NSX in japan makes 297hp, listed as 276hp. WRX STi makes 305- listed at 280hp. So there is no HP limiter like that guy said. the 276 hp for the EVO is just on paper for the government to see.

 

well actually they DO dyno at 280hp. Supra TT dyno at 280hp, GT-R dynoes at 280hp, etc. Before a car goes on sale they have to be checked by the government's dyno to make sure that they're stuck with 280hp. So they can't just CLAIM to have 280hp but in fact have higher.

There is no HP limiter like an electronic device or something like that..... they do it by simply restricting the air-flow. Mainly exhaust. Supra and GT-R can easily dyno at 320hp or 330hp, but in order to keep it at 280 they use very restrictive exhaust systems (swap out the midpipe and the muffler) to keep them at 280hp. (trust me they CAN hold you back that much)

That's how aftermarket exhausts on Supras and GT-Rs can dyno at 40~50hp gain in Japan...... because they got rid of the VERY restrictive exhaust. Same APEXi N1 exhaust can get a Japanese Supra TT from 280hp to 325hp, but the same exhaust can only get US Supra TT from 320hp to 335hp.

 

GlobeCLK - where did you see that the dyno is 280? Because my friend has the Option videos that shows the dyno power in stock form for those cars. They are all over 280hp, before changing anything.
But yes, I agree that the exhaust can change the hp that much, these are turbo cars (except the NSX).

 

I saw the dyno in another Japanese video (RevSpeed I think). They were dynoing the stock Supra and Supra after the exhaust. But that video was back in 99. Maybe back then the gentleman's agreement is more strict? Maybe they don't follow that after 99 or something
