Stage 2 Rex Beat Evo8

[RayfieldsWRX]

ok but still 271 vs 286. 15hp is 15hp don't get me wrong but I don't that would qualify as "much more potent." yes more but not too much or the 30 that was said before. Also I don't usaully use wikipedia b/c they don't have a good rep behind them

I've actually found wikipedia to be quite accurate, as far as car stuff goes.

You seem to want to win an argument. I'll leave you to your nitpicking.

nice no pics or vids ?

Nahh i didnt get to take any vids, but we might do a re-do cause hes making up excuses if we do ill be sure to record it.

The evo8's had 286hp the evo9's had 289hp how's that a "monster" comparsion?

First i would like to say that the 03 evo 8 had a rating of 271hp and the 9's i believe had 286. if 15 more horses doesn't sound like enough to you, have you ever heard of manufactures
underating the power output of a vehicle? take the 03 srt-4 for instance. rated at 215hp and dynoed easily 220whp, or the 03-04 cobras that were rated at 390 and dynoed at 360 to the wheels. The evo 9 is underrated as well. Still not enough info for you? I've ran a bone stock evo 8 and 9 when my STI was bone stock. Completly owned the 8 and the 9 walked me pretty easy. I'm pretty sure i'm not the only one that this has happend to.

Don't let all of that real world stuff get in the way of some self-justifying magazine numbers.

From an (ex, although we still have one in the garage) Evo IX owner I will say the IX is faster than the 8. How much faster really depends on the year 8 we're talking about. The 03-04's didn't have the 10.5 hotside, but the 2005 Evo did.

The IX did come with Mivec, revised stuff in the turbo (not sure on the specifics) and it had a slightly higher boost spike (not too sure if it held more boost to redline).

Take that for what you will, but the IX is definitely faster. A win is a win though.

thats why it makes the power MIVEC and the 10.5 hotside... former VIII owner here but the way i made up the loss was a set of HKS 272's... no more falling on your face @ 5k. good kill but i think you ran into either a stock evo, a bad driver or both....

all he needs is a tbe, mbc, 10.5 hs and get rid of the plastic bov and replace it with one from a XI.. it will be a different car.

The SWRT car is rated at 300hp, so was my stock STi...

I'd dare say the SWRT car would be slightly faster in a 0-60 contest though.

It's not so much about how much power a car makes to the flywheel, but how much of that it can translate to the ground.

The VIII had 225 WHP the IX had 255 WHP... a diff of 30 WHP...

I'll take my pipe and slippers now Fido thanks!

[Alirex02]

i was there i saw the race and the wrx beat the EVO 8.... i wish i could have recorded it but i have an iphone =(..

[wunderboy987]

[Very-Rexy]

Thanks for the info BrianH

[BrianH]

um, no.

Both are twin-scroll, same mani. ..

Compressor housing shot IX left VIII right:


I believe it is 2005 > has a larger exhaust housing 10.4 to 9.8 or something close to that.

Stolen from EVOM:

Evolution 8
Turbo = TD05HR-16G6-9.8T (GSR / USDM)
TD05HRA-16G6-9.8T (RS/RS2 & NZDM) or 6MT:TD05HRA-16G6-10.5T (model unknown)
Nozzle Area (cm2) = 9.8
Turbine = USDM EVO 8 & JDM GSR =Inconel (steel alloy),
RS=Titanium alloy.
Compressor = Aluminium, 68mm wide

Evolution MR aka "8.5"
GSR = TD05HR-16G6-10.5T or TD05HRA-16G6-10.5T (Ti Alloy option)
RS = 6MT:TD05HRA-16G6-10.5T or 5MT:TD05HRA-16G6-9.8T
Nozzle Area (cm2) = 10.5 or 9.8(RS-5speed)
Compressor = Aluminium, 68mm wide


Evolution 9
USDM & JDM = TD05HRA-16G6C-10.5T
Turbine: GSR / GT = Inconel alloy, RS = Titanium alloy
Compressor: GSR / GT = Aluminium, RS = Magnesium Alloy
(??) mm wide (to be verified.)

Nozzle Area (cm2) = 10.5 (note: to be confirmed that RS 5MT has 10.5)

RS E9 turbo part number 1515A059 (approx cost 250,000 yen from Mitsi Japan). *Warning* There are reports of RS magnesium compressor wheel failing if boosted above stock boost.

More Evo 9 Turbo info:
... * New more efficient & larger Compressor preventing compressor surge
... * Better pump gas efficiency
... * Turbine Nozzle Area (cm2) = Large 10.5 Hotside (single flapper)
... * Improve actuator design

wow, that's night and day.
