07 sti built shortblock meth tmic Dom 3xtr 2.4 8cm made 370/350@22. Then I added a txs fmic, 4bar map sensor and got a speed density retune on 26.5 and made 415/405. This turbo really comes alive past 22.

Great build
You should be in the 500's with that fuel/motor work.

Depending on dyno you should easily be in the upper 400's

yeah I found your build thread. Looks good. Why did you decide on the 264's over something like the 272's with as high as you are pulling? spool up?

Id be curious to see what the D3XTR twin scroll does, especially in lower gears and how fast it snaps back after a shift compared to the 10cm. I would think, in theory anyway, it would spool up like a 8cm but still pull like the 10cm?

Larger Cams can act as an obstruction on turbo motors and generally aren't advised. Pistons and Heads are JE.

That is absolutely un true.

They may alter the spool characteristics to a particular set up depending on overlap and duration, or may not yield full gains higher in the rev band because the turbo is too small, but they are absolutely not an obstruction.

I would argue that next to selecting the appropriate turbo charger for one's goals, cams are a close second.

Regardless of your seemingly bigger is better argument, Kelford 264s are a good match for a Dom3xtr 10cm 3"... This is the Dyno Graph with JE Pistons / Heads on Methanol.

im not knocking your set up. you have a good thing rolling. but you peaked at 6000ish and lost 70whp over the course of the next 1500rpm. imo its not enough cam for what you are pushing up top

The Turbo peaked, need more lag (35R) to maintain power at high revs...

Here's a quick highway pull 60-115 on my dom 3xtr,8cm,2.4"@27psi
Does 60-110 in about 5 seconds

Location: Cedar, MI HP Techs MPS-SSLR2.5
Vehicle:
2006 XTI Limited
OBP, Junior tuned 573WHP

Default Dom 3.5XTR

On December 17th I was fortunate to have booked a time with Junior at PnL in Chicago to tune my new XTI build!

It's a new motor build with:
MPS Long Rod 2.5 SB
HP Techs in Detroit built D25 heads; CnC, PnP'd, Hand blended, Super Tech +1mm valve train, Kelford R199B, net 9.5/1 CR
Blouch 3.5XTR, 3"CH, 8cm HS, IWG welded shut
Killer B Holy Header with custom HP Techs, SL EWG up pipe
HP Techs custom built/ Cobb FXT V-banded 3" exhaust
Tial MVR EWG v-banded custom, SuperTrapp mufflered (can you say stealth) exhaust,
ETS TMIC w/ AEM IAT installed in front of the TB
AEM 3.5 bar MAP
Cobb SF intake with cold air box/ 4" ram air from bumper vent

Here are a couple graphs; 93 PG and E85, from my speed density tuning session with Junior at PnL! Junior held back on some timing because of balance issues with the DW 1100cc injectors I had installed at the time of tuning. My fueling system is working well with the Walbro 465, hi amp direct wired, Aeromotive FPR @50 psi and Perrin rails. We were at 80% IDC on E85 and my Blouch 3.5XTR.

I had DW 1100's older style injectors but they were new. I've got one that flows -12% off at 20 % IDC and it is causing fits at mosty lower rpm's but it's where you cruise and the hesitation stutter stuff 1500-3000 sucks big time on E85. It was not as bad on the PG but still there! DW made good on them, gave me an RA# and gave me some new EV14 1000's so that's good but a hassle!!! Junior did not want to push it any harder with the timing as he nor do I trusted the injectors.

Regardless my XTI made very good power even with conservative timing!

I now have ID 1K's and Junior revised the maps for the new injectors. I have been running some logs for him and we are still tweaking the tunes. The power curve is very flat all the way out to Junior's 7800 rpm red-line. It holds 21-22 psi on 93 and 26+ psi on E85 a the way to 7800 rpm. We will bump the rev limit as the motor is 8500 rpm capable and it seems to hold the power.

On one E85 log I saw 28.4 psi by 3640 rpm in 4th gear! That's 450 WTQ at 3600!!

On another E85 log in 3rd gear showed 12 psi of boost at 3500 and then 23 psi at 4000 building to 26 psi and holding that to red-line.

On 93 pump it makes 20 psi by 3700 and 21.5 by 4000 and holds it out to red-line!

I'm very happy with the build and especially the Dom 3.5XTR. I have heard people say the these bigger Blouch turbos are laggy! Laggy? I don't think so!! Do these graphs look laggy? My motor spools much faster on the street than what the dyno graphs show. I think that this build is very well balanced in the parts selection and execution, it breaths very well and the results show this!
