Nice numbers/curves. Great to see that the power doesn't fall off at higher rpm's, something that I hate with the VF39. What psi were you tuned to?

I think it was 22psi and 20 psi. i love the torque and the tgv deletes made throttle response so much better

looks like a great combination of parts you got going on there.

Most STI's I see loose anywhere from 40-100 hp from 6K to 7K rpms.

Your car only looses about 10-15, that makes for a great top end.

I was just driving around today, it is the perfect street setup, gobs of passing power and torque, at exactly the rpms i need, (05 sti 6-speed).

Nasty! Good to see more blouch 2.5 users. I need to get my car finished and dyno'd or taken to the track to back the underrated blouch 2.5.

would love to see how the DOM 2.5R perform on a 2.5wrx....... DOM 2.5R should have a better respone and faster spool than a TD05-20G right??

yeah that is true, but still a 20g has a smaller wheel and that tiny hotside. it would be close either way, probably not even too noticable.

I agree. My bet is that a 2.5L motor would spool either turbo so well that any difference would minimal. But a td05 20g should still be a little quicker.

it should spool slower than the td05 20g, although it spools a bit faster than the atp 3071 due to the housings

From what I've read, the 8cm spools just as quickly as a 7cm housing on the 2.5L motors. The 7cm should probably be avoided. Common opinion of people I trust is that the 7cm is just too small to handle the volume of gas produced by an ej255/7.

Yeah definitely, considering that the 2.0 liter EVO comes stock with a 10cm2 housing too.

I think a TD06-20g 8cm2 makes just as power with the same spool as the dom 2.5r. If i had to do it over again i'd still get the dom 2.5r for the ballbearing badassness lol

ChuiSTi, I'm envious of your setup. That 2.5r has a 47 lb/min compressor wheel as opposed to the 40 lb/min rating of an 18g, so I wouldn't worry about any kind of buyer's remorse.

Is your coolant feed line rubbing slightly against the corner of the APS TMIC? I couldn't get the pass tmic bolt on due to the line.

haha thanks jason!

jutes,

i used some thick metal washers from home depot (2-3 of them) between the tmic and the passenger side mount, elevated the passenger side about 1/4-1/2 inch and it doesn't rub on the coolant line anymore

Ahh well. Mine is rubbing against the clamp, not the line so it doesn't really matter.

I'm interested to see the differences in spool with an EWG when I get mine tooned in a months time.
