What are we fighting about again?

I've driven both cars. Sure the 9 feels a little better but it certainly is not a HUGE change.

I'm drunk with power though. Both the 05 and 06 felt slow to me.

 

Then you aren't driving the right cars, or you're not driving an 03 with a stock turbo.

 

once a 10.5 is fitted to an 03 or 04, the car will be exactly the same as a 05 with the same mods. the 06 seems to have a 20 whp edge even without cams.. thats impressive.

 

20WHP....I think not.

Eitherway if I was EVOless I would definately get the 06 over a used 05. My dealer is selling at invoice with whatever perks are available this month.

 

Hmm... I thought the MIVEC system on the Evo was variable valve timing on the intake cam only. This would make it more similar to the Toyota VVTi system, which is basically a computer controlled, oil pressure driven adjustable cam gear.

Honda's performance oriented "three rocker" VTEC actually uses a low lift cam at lower rpm's, and switches to a high lift cam at higher rpm's. Toyota does the same thing (though different execution) with their VVTLi system. However, it appears is developing a similar system, though from what I could find, it is first appearing on the (JDM?) Grandia 2.4L. Does anyone have any more info on this?

BTW, sorry about hijacking the thread.

 

What I'm trying to say (although I don't think anyone is listening) is that The MIVEC is all about changing the valve timing by means of a change to the profile of the cam. It's the same principle that all the manufacturers are using to optimize the function of the engine, the rest is details........

 

One thing I will say is that Vishnu has done a very good job compiling information for the 9. They have brought it to a level so that the enduser can get a better understanding of the stock ecu.
Keep up the good work Shiv.

 

I guess since your car is modifed with a tbe exhaust and has engine management you can't tell the difference, however when tuners provide solid information with dyno sheets, then your only excuse for not "getting" the power potential for the 9's is ignorance.

Its not exactly track season in USA so don't hold your breath to long to find those time slips. Not every single dyno to be supported with a time slip, because tuners like Shiv/Nick/etc. have no reason to inflate their numbers to make their customers feel good.

 

I wasn't too impressed with the 10.5 hotside on my '03 - added a little lag though

 

you know what.. for once it seems other tuners are not inflating their numbers.... part of this is due to dynos that no longer read SUPER high (remember its now stylish to have a low reading dyno) .. but if you look arround most tuners are not getting near shivs 270 whp with just a flash. In comparison a dyno jet flash would need to make 290-300 whp to be equal to the 270. I have seen a couple tuners that use mustang dynos only makin arround 235 whp after flash.

 

the 10.5 is a great mod in my opinion.. the max power output on race gas is about 20 whp higher with the 10.5. As far as the miniscule increase in lag, i think that is worth the extra power.

 

Ah - me just run pump

 

My slightly modded 03 is definately quicker than a stock 05 or 06. Once modded Im sure they will feel the same with the 06 edging everyone slightly...but not 30WHP especially against a cammed non-mivec car.

This will be my last post in this thread. I believe the numbers Vishnu is providing but I also believe all the other dyno numbers. Every year there are some strong factory freaks. I'll just wait till spring to see what all those 9 run. So far they've all ran about the same thing the 05s run. Supposedly....30WHP should be worth at least 3MPH so trapping 109/110 should be normal on a stock nine.

 

whats with people hating teh IX, i dont have one but im happy that it is making more power. whats so hard to believe? shiv posted stock vs flashed dyno charts. what more do people need? You people dont have to believe they are faster, but you will see next track season.

 

I stopped caring about 3 months ago - when word was spreading from the UK to watch out for the IX
