I would have done the same. So with that addressed, is there anything else BL recommends to achieve your goals with this build to ensure it is done 100% this time?

Not really. Zohair offered good pricing on future purchases. But this was a bit setback, so new purchases are a long way off.

I hate seeing other GTR owners have issues during the build process!  A lot of times problems occur for various reasons, occasionally outside one's control. In the end experienced shops and trust in vendors will allow you to achieve your goals. I'm happy to see Boost Logic step up in the customer service department and help out a member in a fair manner. Zohair has always handled every aspect of the business with professionalism and resolve. I can't wait to see how your car (AWDTT) turns out with the Boost Logic 1050x turbofold kit!!

 

On a technical note.. we have used Boost Logic Titanium intakes without issue. I don't see any way material can come off and run through the compressor. There are no pieces large enough to cause that sort of damage that could come from the intakes. I would search for a foreign object in that side intercooler inlet. Likely what caused the damage is large enough to not pass completely through the intercooler core.

Post up some pictures of the old CHRA when you have it removed. 

 

Based on the pictures you provided, I have to disagree that "sloppy work" was involved. Mind you I have no idea who worked on the car. Now, I may have not taken apart a GTR as many times as some others here, but I can't think of a single item aside from a MAF screw, that is small enough to ONLY cause those small knicks in the compressor wheel. A bolt leftover in an intake pipe would have annihilated the compressor wheel, not just chipped it like that. 

 

I also don't think sloppy welding or weld slag was the cause either though. Since those are put together by hand I'm sure something like that would have gone noticed before they were shipped out. Fusion welding causes very little, if any slag at all either.

 

I'd venture to guess the most probable cause was either the engine was run at one point without filters installed, or there was a small rock or something inside the pipe, or filter when ti was assembled.

I definitely wouldn't attribute this to a bolt or object that large. I am in agreement Tim, it was likely a small rock. Something an eighth to quarter inch round. I believe the sloppy work was more directed towards install issues in the beginning. The problems that occurred on install and the fabrication necessary to mate up to factory piping would not have been an issue with a large experienced shop. Fit and finish is the responsibility of the installer. If the shop feels a product requires more work to install than necessary then they will not to use or recommend that product in the future. Or they work with the manufacturer to improve certain points.

Again I hate that the op has had such a headache from this venture. I do believe he would of had a great experience in the hands of a well known shop, regardless of the product.

This should wrap this thread up.  Irma caused some delays.  I figured I'd show the difference between wire wheeling and not wire wheeling the inside of a these intakes.  Metal dots almost all gone, surface is smooth, although a few bad spots remain.  For $1K, I don't think it's unreasonable to wire brush these pipes before shipping.  Just saying.

One more.  I should point out that I'm paying the labor to have this done.  It should have been done by the manufacturer.  As the gallery shows, other companies do it -- and polish them as well.

It's nice when things work out.  I was able to track the car at Sebring this weekend with the Boost Logic 1050X turbos.  The only other mod was an AMS fuel rail kit which just prerequisite for an upcoming fuel pump upgrade.  By mistake, I was using Bill's Map 2,  street kill mode which allows about 22 PSI.  With that extra HP and timing, I recorded a 176 mph at the end of Ullman straight before braking.  Damn, this car is fast.  After I realized the mistake, I changed it to the road course map before I blew something up.  Because my IDC is around 86%, Bill is not going to give me any more boost.  Because stock clutches, no early boost, so response was poor.  Exiting sharp turns in 3rd gear was excruciating, so I downshifted to 2nd to keep the RPMs up so I could get some boost.  That worked but the gas mileage dropped to 2.8 MPH.  I think that works out to 1.7 gallons of 93 octane gas per lap!  Anyway, the car and the turbos were awesome.  Looking forward to Daytona.

Congrats man.  Glad to hear you're enjoying it.

 

176 is fucking booking it.  What brake setup are you running again?

Stillen's rebranded ST CCM.

 

Here are some laps at 18-19 PSI vs 22-23.  I didn't have the AiM recording on the session with kill mode map.

Just bought a slightly, almost new set of Dodson clutches.  My new guy Danny has fabricated a fuel basket to run 2 high pressure Walbro 485s.  Pictures coming soon.  Time to update my build thread.

Your observations are right. Once I put in the BL Race Intercooler, the airflow to the HKS trans oil cooler changed and the temps climbed.  Before the BL IC my car used to be the only GT-R on the track on hot days.  Either way 260s is acceptable because I change out the Dodson GR6 trans oil after every event. So, it's a calculated risk, but as long as I replace fluids every event, I think we're good.

Your car is perfectly balanced watching the video..... Great to see equal time spent on power and stopping. Maybe just relocate trans cooler.

With virtually zero miles on the car, and after it had dyno-ed at over 732 WHP/590 TQ on pump gas (torque-limited by Bill @ SiR's safe tune), my guy Danny did one final inspection and found this.
 
It is the final straw with Boost Logic.  From the pictures below, you can see that there is a clear possibility that the crappy welds inside of the intake pipes could have easily yielded a piece of slag that damaged the compressor wheel.  Everybody knows that if a washer or screw or some other fastener was left in the filter, the damage would have destroyed the wheel, not just nick it like this.
 
 
 
I sent the picture above to BL along with a sample picture from these below.  They refuse to take responsibility for the damage and offered to cut me a break by selling me a replacement CHRA for $1197 (their price).
 
If this had been the first problem I had with this company, I'd probably pay the $1197.  But this is the last of a long list of screw-ups on their part.
 
1. Sent $8800 worth of turbos with cracked waste gate ports.
2. Compressor outlet didn't fit OEM hoses as advertised.
3. Wastegates were missing plugs, causing weird behavior.
4. Wastegate actuator nuts fell off during dyno testing.
5. Wastegate actuator diaphragm turned sideways, causing it to stay open, mimicking a boost leak.
6. Welds that are so poorly done that you can cut yourself if you put your hand inside.
 
And they suggested that we ran the car without filters.  Judge for yourself.

 

 

 
 
 
 
 
 
 

Compare those welds with these.  I have more pictures that are even sweeter than these.  But it should be painfully obvious that the extra $1000 I overpaid for the intake kit wasn't worth it and was quite likely the reason that the wheel was damaged the way it was.

 

 
 
 
At this point, I'm considering my options.  I'm open to suggestions.

 

 

Yea, i could see this happening. This is a email to a different "reputable vendor" a few months ago regarding a brand new set of 3" intakes, I will leave out the vendors name;

 

 I have purchased a pair of your 3” Intakes" and just not impressed at all. I was excited to get them in today and my initial impression at a glance was good. Then I got looking in them and there were aluminum filings inside the intake tubes and they were dirty. I started cleaning them and blowing them out and realized there was a small gap between the MAP flange and the tube and there was filings stuck in there....it appears somebody went around there with a die grinder to clean off burs, but didn't clean the intakes after. So I flushed them with soapy water and blew them out ] until I felt they were clean. Now, there is powder coat overspray inside the tubes that is flaking off....What now????? I paid $600.00 for these and they should be ready to install.

Case closed.  Besides the inside of the intake pipes not being wire brushed and/or polished, the turbos and intercooler piping work well.  All other problems were installation-related.  For anyone wondering whether the 1050X turbos make over 1000 HP, I would say, easily on E85. They make 850-900 on pump gas at 26 PSI.
