Default Blouch 2.5XT-R polka pickle anyone?

Just wandering what everyones thoughts are about the new 2.5XT-R turbo is.... I was originally looking into purchasing their 20g when I came across the 2.5 and read up on that one and was leaning towards that turbo when all the sudden I see a new design of it the 2.5xt-r.

I saw the post about the 3.0xt-r in proven bragging they mentioned that it spooled earlier then the regular 3.0 becuase of the new billet wheel. So can we assume the same thing will happen with the 2.5xt-r, is it going to spool alittle sooner but still make more power. Is this turbo just an all around better design and going to be a better performing turbo then the first 2.5?

I'm just trying to understand the what the difference between the two mean for performance as I'd like to get a new turbo for my STi sometime. Also if I had this turbo would my Perrin 3in 2 sec dp with 2 high flow cats be any kind of restriction.

+2 about getting this turbo! Because it is smaller than the DOM 3 I am assuming it will spool faster and now that the new dom 2.5 XT-R has the billet wheel (mentioned above) it will spool even sooner??? Potentially peak boost close to 3.5K rpm or no???

I also have a Perrin catted down pipe (one peice) which is the divorced or twin dump downpipe and I was also wondering if this would be a restriction to either one of these turbos????

I emailed blouch about this as well earlier tonight. Havent gotten a response yet. I was looking at a 2.5r as well. Im curious on the spool. I dont care about getting more power, although it is a bonus, but if it is faster spooling, Im all over it!

Thanks, thats good to know! I have an 09 WRX so I have to get a fmic before I can get any other turbo. Good thing my fmic is going to be here tomorrow

Also Chris from Perrin said the downpipe should not be any kind of restriction as they were running over 400whp with their 2 peice catted downpipe

Sweet so my dp should be okay. So now that you have your FMIC coming in and all you should buy the 2.5XT-R and let us know how it is.

I ordered one a few days ago. Hope to have it soon, but may be a little while before I can post results.

Will run with a top mount Spearco, Cobb DP, and 750-850cc injectors. I really want to run the stock sti catback so may try both on the dyno to see it the stock one is really holding me back or not.

You'll have to remember to post your results as I can't wait to see what it does. If i get this turbo or a turbo for that matter i would like to run a setup similar to yours but maybe add in pnp headers, turbo inlet and cai.

I figured it would spool a bit slower than the 2.5R due to being a 10cm housing.

I tried calling them yesturday but the techs were out sick. Today no-one answered!

I was debating between the 68HTA (hard to argue the price/ performace) and the 2.5R with a lean towards the later. Now this has me curious.

That's what I figured too. But maybe with the billet wheel it'll be very close but keep pulling past the 2.5.

I took a gamble given no real user data out there. We'll see.

I would expect similar results in the change just like people expected for the 3.0.
They expected a little more lag(bigger exhaust side)
but ended up with ever so slightly faster spool (due to better wheel)

So i would assume that the results will be very similar.

Got a response from Blouch to my email asking about spool.

Quote:
Spool should be very close to the same with the new 2.5XT-R. The billet compressor wheel is over 25% lighter then the standard cast wheel it also has new aero that improves efficiency and flow. Currently only the new 3.0 and 4.0XTR are currently for sale. We should be finishing up the 2.5XT-R in the next few weeks.

thanks for the update. spool comparisons would be great, indeed. the power is definitely there that i want. now, how significant is the difference in spool between them?

Since my post #20, Blouch said that they have not finished the 2.5xtr yet, so it doesnt surprise me that no one has it.

I really want to see back to back dyno charts with boost vs the 2.5r
