Specs on the Evo X

[madman]

"The new 4B11 T/C produces more power than its predecessor: 291 hp at 6,500 rpm (vs. 286 hp at 6,500 rpm) and 300 lb.-ft. of peak torque at 4,400 rpm (vs. 289 lb.-ft. at 3,500 rpm). The 4B11 T/C provides a broader torque curve, as well. A revised turbocharger yields up to 20-percent quicker response at lower engine speeds versus the 2006 engine's turbocharger"

Can somone help me out here? If the peak torgue hits later than the IX, at 4,400 rpm, would that indicate that it's a slower spooling turbo? But yet it says it's 20% better response than the IX.

I'm confused

I don't know. The new turbo and MIVEC on the exhaust and intake cams all play a roll. According to 0-60 magazine (winter issue) the turbo is a;
TD05H-152G6-12T

We are all familiar with the TD05H turbine wheel...

152G6??? I've heard of 15G's and 16G6's but a 152G6???

12T??? Again; I've heard of 9.8T and 10.5T. Is this a 12cm turbine housing? That's huge if it is.

[BAMBAM]

Well is it a 2.0? Also you can change the rpm's range by the cams you have in it. So man that is how they are getting the high rpms numbers. not sure on the cam size tho. I am planing on looking at it as soon as it comes into town.

[TSiBER RYDER]

if it really is a 12cm housing, that's probably why it makes max tq at 4400 rpm. imagine advancing the mivec tables a little bit to help spool and a good tune. i bet that thing will make some sweet numbers.

[turbolarry]

Yes. 2.0L aluminum head and block.

[BAMBAM]

Any one know the cam size? or more on the turbo?

[turbolarry]

The new issue of SCC has some info on the Evo X (but nothing about the cams/turbo);

"The new MIVEC, higher compression, and new turbo design contribute to a claimed 20 percent increase in boost response at low engine speeds..."
Retard the exhaust cam or the timing maybe???

"Although some people see the use of an all-aluminum block and software -particular TC-SST transmission as the end for serious Evo tuning, Mitsubishi has left some leeway. The manual transmission isn't tied into the Gestapo stability and engine management computers. And the company left out direct injection, which at least allows tuners to upgrade to larger injectors and use conventional fuel pump upgrades. Mitsubishi also managed to pass evaporative emissions with a return type fuel system, which saves the hassel of replumbing new lines for fuel thirsty big boost."
Appearently the aluminum blocks are cast with a reinforcing "ladder structure" for added strength too.

Evo X GSR: 3344 lbs.
Evo X MR: 3388 lbs.
Evo IX: 3263 lbs.

That's a bit more heft.

[BAMBAM]

My EVO VIII SSL is weighed in at 3540 with me in it. take me out and it sets alone at 3340.

3340? it is confusing yar make it clear,
