Is MIVEC what makes evo 9's make so much more power then the 8's????

 

The MIVEC helps with the low end more than anything else but its really the evo 9 turbo that is the monster. The efficency of the inline 4 and short exhaust manifold and SUPER efficient turbo design just makes that 16g perform like no other.

It's amazing how little mods you need on that car to make them run in the 11's.

 

Its the mivec that allows more low end torque while also allowing more the car to run 23psi or so on pump without knocking. The IX also had a larger turbo (compressor side), better gearing than the VIII, and revised oil cooling passages (also helps in running safer on pump)

I think a evo VIII on 110 with a 20g-9 turbo almost hit 350whp on the GST dyno today

There are also quite a few IXs hitting 330whp+ on 100 octane pump...

300-310whp seems to be the limit without adding cams or 100 octane though for the IXs

Andy@Speedelement street tuned a IX with just a TBE/licp/MBC that ran 11.91 2 weekends ago at sac

 

Yeah, this is the big divider between stock turbo STis and stock turbo evos

Not the mention the evo FMIC can handle 350whp+ before heatsoaking

 

that would be interesting to see since every dyno day i have ever seen on that exact same dyno with Evos with turbo-back and flash have been in the 225-235 range, I guess ther MBC adds 65whp?? I'll be there in any case

 

Well, evo tuning has come a long way in the past year or so

An evo 03 VIII with a TBE and ****ty works flash will put down 235hp

Bone stock IXs put down 235-240whp. EIP/Speedelement/GST have been pumping out 300whp evos on pump for the last 6 months

 

yeah i went to a couple EVO days at the old shop a year or two ago and this is exactly what the VIIIs were hitting with TBEs and P2s, so i hope things have progressed, you gonna be there Kyle?

 

"Shoulda bought an EVO"..in ur case a red gsr with SSL.
I've told you this for awhile...and whata you do?...buy a WRX wagon.


haha, werd :rotfl:

 

For 07 The STis appear to be faster aswell, should go low 12s with a tune/TBE...tho maybe not quite as fast the EVO 9.

 

Krinkov...HAhaha

 

haha, hit 'EDIT' instead of 'QUOTE' , thats what I get for replying half-drunk

anyhow, I'll be out there on Sat for the dyno day, been wanting to see how the EVOs have been doing. I was there todat to see that blue EVO with the twin scroll/20G turbo on 100 oct, sounded and looked wicked, we chased it out of the parking lot tonite and I must admit that thing was awesome Im hitting 296/305 with the TD05 20G in mone, would love to swao with an EVO with the same setup to get a comparison

 

Well you know as well as I do that our white STi's are going to put alot of evo's to bed.

 

I dont think I'll make it out to the dyno day. Im still un-tuned and the guy doing the tooning is in china until the 20th

 

Yeah just wait until those guys slap a GT35r on with a 100oct tune

 

I gotta disagree with this one. The gearing in the evo's make it very difficult to hit 10's with. I'd like to defer to our resident bench racer MARKSTI to elaborate more specifically on this...
