First: Don't take this personally. This is just friendly argument.

That rediculous. Setting aside any difference in peak numbers, the power delivery is quite a bit better on the IX. The fact that you haven't seen the difference in a drag racing venue doesn't mean it isn't there.

I haven't been following the IX threads very closely, but I have driven IXs on open New Mexico roads. While my modified VIII RS is probably as fast as (or faster than) the IX MR I took through the jemez mountains, the engine is surely less enjoyable when not at 10/10ths. MIVEC and the new turbo make a difference, regardless of peak numbers.

Dont worry guys, we will find closure on what really 09 can do, once the track here in Sacramento Raceway is open, I will run it.
Honestly, I hope Shiv can run the car himself since I know he is more experience than I am.
My run may not do justice. In any case I may post it upon request.
Will you do it Shiv?

If I find it slow then I will sell my turbo and downpipe and upgrade to a bigger turbo kit. (seriously)
But first I will upgrade my 1/4 mile driving skills. Stay tune.

 

^ trust me, you_do_not_want_Shiv driving your car on a 1/4 mile track. He'll be lucky to cut a 2.00 60 foot, hehe.

Well I just wait and see then. I'm just saying I've driven a stock 05 and stock 06 back to back ....felt nearly identical to me. It certainly isn't 30HP.

Personally I dont really care....I'm waiting to see what the TEN has to offer. Until then my mid 12 second 03 will suit me just fine! Enjoy your evo's no matter what year it is.

 

the ct9a evos are all great change the turbo and they are all the same, but the ten is gonna without 4g63. nuff said!


edit...bottom line is...all evos tested got low 13's.

 

Its hard to judge a motor before you know anything about it. What if its an all aluminum 4G63?

 

you guys are forgetting... some people have already hit 12.8 with their bone stock evo 9s.

 

Here are some stock whp figures for you.

First up, some #’s from Shiv and Vishnu’s DynoDynamics Dyno:

Next up is a post from skiracer who had his car dyno’d @ Tuning Technologies AWD Dynojet here in SoCal. I know this chart is correct because it was posted up by TT themselves in another forum. Again, this is a stock IX and the 03-04 Evo #’s are mentioned below the picture which confirm Shiv's findings:

However, there is one place I’ve seen that shows that the IX’s have no real whp gain over the VIII’s. Some graphs from Buschur Racing's Mustang Dyno has demonstrated about a 200-210whp range for stock Evo IX’s which are the same as the 200-210whp range of the VIII’s on his dyno:

(*all of the following pics were posted up by Dynoflash, not Buschur*)

(Stock IX #’s are the base run #’s):




(Actual stock IX vs. stock VIII graph)


There are other shops that have stated the same thing as Vishnu & TT, but i'm at work and I can't spend longer than the 25 minutes on this that I have so far..

My conclusion: It is reasonable to conclude that we can trust Shiv’s #’s stating a ~10whp gain from the 03/04 Evo 8 to the 05 Evo 8, and a ~15whp gain going from an 05 Evo 8 to a 06 Evo 9. (not 30whp from 05-06)

I think its great that you dug all that up.

Ok the 06 might have 15 more HP than an 05 or 03 with hotside.
Barely noticable from the drivers seat. Not worth trading an 03-05 for.

 

Ditto! That's like wanting me to race your car on a road course to see how it performs. That result likely would end in seeing how the Evo handles on its roof. FWIW Shiv is not Big Daddy Don Garrletts or John Force but he can Kart his azz off and outrace soccer moms in residential zones and kick their azzes on onramps/offramps. Us So Cal boys want revenge against team Vishnu at the Drags but Shiv et al is scurred. Stick to 9 hp Karting Shiv and leave the manly sport to the Men.

 

I agree that 15whp is barely noticeable from the drivers seat, but I would think that the stock turbo/ecu tuning potential (plus the seats and front bumper) would make it worth it for some with 03's/04's to trade in.

However, trading in an 05 for an 06 is not worth the loss in money alone from the sale/trade.

It's just my opinion but I think the difference between a stock IX and VIII is very noticeable on the street. There's a 20-30lb-ft advantage around 3500rpm! And a stronger pull up top (all the way to redline).

What annoys me is that your make all these statements or claims with out taking the steps to actually do some research and back up your thinking. Your just going off of your opinion and your feelings and sorry to say but the actual numbers don't back you up. What you are saying has already been discussed and compared, and while some IXs may dyno similiar to VIIIs stock, there is no denying the fact that the ones tested so far have been really impressive. You want us to back up our statements when we been following the info all along, why don't you go and back up your claims? Find me all the dynos of 03, 04, 05 EVO VIIIs making 300WHP on a DD with just a flash and exhaust, I'm waiting?

 

That would make the Evo X worse than all of the other evo's. Aluminum does not have the heat tolerance properties that iron has. Which would mean that less boost could be run through the motor, and cranking it up through flashes would allow for things to go boom really fast. This is the main reason that STi's do not make as much power as evo's without having the motor rebuilt, because the block is aluminum. Seeing 20 psi with a 21+psi spike from the factory would no longer exist, and you wouldn't see as much power especially if they plan on keeping it 2l. Another thing that would affect is getting a quick flash to up boost and make more hp, because...well you get it things would go all wrong.

 

I think what Shiv and Dave Coleman said is what's important for most of us - 300whp quicker spool, stronger midrange torque, blah blah blah....
