Any feedback on Comp Turbo. Looking at running a pair of their new CT43 67/75. Supposedly rated at 1,100 each.
Dr. Boost
Some local guys have used them and like them, they were dealt by a local guy that really is a fan too. I haven't used one, but they were doing an aluminum CHRA years ago, and that "triplex" ball bearing system they use is supposed to be ultra rugged. I've heard some negative feedback as far as some of their exhaust wheels, one guy on here was talking about having a 100 trim wheel on some big-ish midframe, couldn't make it work right, (not that anyone could make a 100 trim wheel do well). That's about all I know.
buddy broke one of their 98mm turbos wiith the triplex ball bearing. First few passes on the dyno were good and made good power. First attempt on the 2 step and the bearing broke and allowed the wheel to touch down. Comp stood behind it and sent a new one before even recieving the old.

Comp Turbo; The ridiculousness continues...
As some of you may have seen my post last year regarding my ridiculous issues with Comp Turbo Technologies, I am unfortunately in the position of writing another post to follow up on how Comp “resolved” the problem with me.
I know this is a long post, I have tried to keep it as to the point as possible, but the devil is in the details here:
- Late 2012 I purchased a brand new custom CT591106 for my CTS-V for $2800
- Within 1200 miles the CT591MM began smoking and had a concerning amount of shaft play.
- As I was going to go with a bigger motor in April 2013 I called Comp and asked if they could take the turbo in and check the issues regarding the smoking and shaft play and while they had it also convert the unit to a bigger turbine housing, Ernie a “manager” told me to send it in and they would have it back within “10-14 days of receipt”
- By June of 2013, having not received the turbo back despite countless calls, most of which I was told I would be called back by the receptionist, yet having never received a single incoming call and in a rush to make an event (Pikes Peak Airstrip Attack) I was forced to source a different turbo.
- A few days after the event, the owner of Comp, “Joe” called me to apologize for the problems. I told him I did not need the turbo anymore and would appreciate a refund; he said he could give me a refund, but there would be a restocking fee of 30% ($840+) after going around and around, Joe offered to replace the turbo they had, with a brand new turbo of my choice, while this wasn't what I wanted, it seemed better than losing $840.. but in retrospect I should have taken it.
- I then spent around 30 minutes on the phone with Ernie discussing spec’s for the new turbo they were going to send me, we concluded with a CT58092, and I was told it would ship within 2-3 weeks.
- 2 ½ MONTHS later I received a package from comp turbo… I finally received my new turbo… NOPE, somewhere along the lines, Comp had decided everything they told me didn’t matter, and they would just send me my old turbo, which had tell tale marks from my installation and carbon build up on the turbine from being used (by me).
- Not only was this my old turbo, but it still had the shaft play it had when I sent it in, the only noticeable differences where that the Vband and turbine housing were spray painted black which turned to ash and flaked off within minutes of installing and starting the engine.
- Of course I called Comp immediately to discuss, and as is common practice was told “someone” would call me back that day.
- A week later after several more calls I finally got in touch with Ernie. Ernie proceeded to tell me, that this was not my old turbo, and it was a new 8092… Ernie proceeded to sit there on the phone and act as if I was stupid enough that he could convince me that this used turbo which used to be mine, was a new one. Even when I sat there on the phone with him while measuring the turbo, confirming it was indeed a 91/106 and not the 80/92 we discussed, he still had the audacity to tell me I was measuring wrong and that you don’t measure comps by the compressor inducer and the turbine exducer which “coincidentally” just happened to be the specs of my original turbo.
- Having no other options, I stopped arguing on the size and asked Ernie, if they had at least tested this turbo, as it seemed to still have the same shaft play Ernie replied “ that turbo is in perfect condition, we fully tested it before sending to you”.
- Against my better judgment I installed the turbo on my truck a 2010 Silverado 6.2 when it was ready in November of 2014. After a 500 mile break-in I began tuning the truck. After a few pulls it began smoking a little through the exhaust, but not enough that I was worried, more just frustrated and thinking I would need a new anything but Comp turbo ,soon. And then after another few pulls I threw a rod through the block. After reviewing the logs, it was clear that something went very wrong, I was commanding very conservative timing, anything above 105KPA (3.4PSI at Colorado altitude) was set to see from 14* down to 11* of advance. On all the pulls prior to this that is what it saw, however on the last pull it stayed almost completely at the idle settings of 40* of advance.
- After thinking about it I decided to pull my MAF sensor, and found that it was covered in oil. After pulling my intercooler and draining about a ¼ quart of oil from it, it was pretty clear that the most likely cause of my catastrophic engine failure was caused by the turbo, blowing such a large amount of oil through the intake that it coated the MAF sensor to the point that it was unable to do its job and the ECU could not meter the air going through it and work properly to retard timing according to airflow(a measly 8psi total).
- After several attempts I finally got in touch with Joe, again asking for a refund, JOE TOLD ME HE WOULD NOT REFUND MY MONEY ANYMORE BECAUSE NOW I WAS PASSED THE ONE YEAR MARK even though the turbo had less than 1000 miles since they sent it to me.. He agreed that If I sent the turbo in, and it tested bad, they would send me a new turbo.
- December of 2014 I sent the turbo to Comp.
- Late January 2015 they still had not given any word.
- Late February after several calls Ernie told me they had not tested my turbo but that Joe had agreed to send me a new CT5 8092, which would ship out within 2 weeks.
- Late March, I called to check status as 4 weeks later I had not received. I spoke with Joe, he said the turbo had not shipped yet but he himself would ensure it shipped that day, before getting off of the phone I told Joe that I had just recently moved, and gave him my new address, Joe read the address back to me.
- Mid April 2015 I still had not received the turbo, so I call again, speaking with the receptionist she told me my turbo had been shipped, I asked which address it had shipped to, and of course she proceeded to read back my OLD ADDRESS. Asking to speak to Joe or Ernie, I was told one of them would call me back, no one did.
- The next day speaking with Ernie, he told me I would have to wait until Fedex Found the turbo, that was marked delivered to my old address. I asked how long this would take, he said it could be up to a month. I told Ernie If I didn’t have a turbo within 2 weeks I would go public with my experience with comp turbo.
- Ernie and Joe, continued to stall, until finally on May 22nd 2015 I made a post similar to this one, listing the problems I have dealt with. In two days it had over 30,000 shares, 100,000 views and hundreds of people commenting that they had seen the exact same type of issues.
- Very soon I received my first incoming call ever from Comp Turbo, despite being told countless times I would be called back over the course of two years! It was Ernie, he acted very hurt that I would do what I specifically warned them on multiple occasions that I would with regards to making the post. He even had the nerve to say it was unethical! I simply explained that if they didn’t like me telling the world how I had been treated, that they should not had treated me like that.
- He told me that, what a coincidence, my turbo had been found and it was on its way to me (only a short 7 months after I had sent it to them). He went on to explain and I suppose take me on a guilt trip about the ongoing problems that they had faced and the difficulties they see as a “struggling company in a competitive industry”. To which I told him repeatedly, as a business owner myself, the things that they had failed at the most were very avoidable; they consisted simply of calling the customers back when they say they will, and not promising things they won’t deliver.
- Feeling sympathy for god knows what reason, I removed the post after I got tracking information.
- Apparently I had sparked a lot of people to come out of the wood work and tell their story about how comp treated them, Ernie contacted me again, asking me if I could help them because a lot of people were posting negative reviews… I was dumbfounded at this request and explained that I had no control over their other customers posting reviews… And looking at their facebook page today, it appears that they have removed the option for people to leave reviews, companies who do good jobs for their customers don’t typically do this.
- Still, it wasn't until August, 7, 2015 that I actually received the turbo (9 months after I sent mine in, almost 3 years that I had been dealing with this crap). And since then it has sat in the box in my basement I've had a CX Racing 80mm turbo installed which worked perfectly fine for me, while I was tempted to sell the Comp turbo I didn’t want to take the chance that if it was bad, someone would be pointing the finger at me. And I figured my cheap ebay $450 turbo wouldn't last long anyways…
- Last month (March 2016) my CX finally started smoking and I installed the brand new Comp that had been sitting since August of last year, brand new in box. It seemed like a quality turbo. I put 1000miles on it before I ever did any WOT pulls, not wanting to take any chances with the considerable history I’ve had with Comp’s turbo’s.
- Once it was broke in, and I did the first few pulls it did fine and felt great, this was around 10psi. Of Course I religiously checked my charge piping for any signs of oil, thankfully there were none. Once I tried to turn it up however, I found that no matter what, the turbo will not exceed 13.9PSI, I'd have the boost controller cranked all the way, the wastegates don’t even open; still 13.9PSI.
- Nothing was changed whatsoever other than unbolting my old turbo, and bolting on the new one, the CX Racing turbo was making 20psi no problem. I checked for boost leaks with a smoke machine, and inspected closely for exhaust leaks nothing.
- Still trying to give the benefit of the doubt, thinking maybe it is something with my truck, I tried swapping the turbo with a friend’s 5.3 Camaro 13.9PSI!
- At this point I was furious; after 3 years, and losing a motor because of Comp’s junk, I still don’t have a working turbo. This morning I wrote a polite email to Ernie and Joe asking to send back the turbo for a refund. After not hearing back all day I called and spoke with Joe.
- Joe told me that “no company would give me a refund, that this turbo is in essence 3 years old”. Even after I told him no, this turbo is brand new and has no more than 1200 miles on it, 1000 of which were break in, he told me that I should be thankful that they had tried to help me in the past, but were done being “harassed”. He went on to say that this exact turbo works great for everyone else, and that there is some inexplicable problem with both the cars I tested the turbo on. He could not explain why other turbo’s work fine on these vehicles, but insisted the turbo I have is fine… I told Joe one last time, all I wanted was a refund, I had nothing to gain, if it was up to me his turbo would work. He started offering to test the turbo, I explained that I had been dealing with this shit for over 3 years, and would not accept anything other than a refund, he refused. I let him know I would be going public again, he said "that is fine with me"
I only took the time to write all of this so that people will hopefully not make the same mistake as me, I am out $2800, a $3000+ motor, and several hours dealing with these clowns...
PS If you want to buy a 80mm turbo that’s good to 13psi for who knows how long, let me know, ill sell it cheap, right now its just an extremely expensive paper weight. :-/

Comp are a hit and miss mostly miss a lot of people were fans when they initially were released but the longevity issues started popping up and even some of the best tuners struggled to get more than 2000 miles out of them before a rebuild then everyone jumped ship
I only know one person that runs a comp turbo and he has had numerous problems with them, including a compressor wheel breaking in half as well as other problems.
He is "sponsored" by them yet still pays for there f ups. The funny thing is this idiot still pledges undying loyalty to these guys.

Christ. I feel more confident in my GT45's than I would running a Comp turbo after all these stories. Just google Comp turbo issues.
I had a buddy that had 2 of their billet wheel 122mm turbos burn up between a couple dyno runs and like 3 passes they both seized up
Interesting, to say the least. I don't think I'll be buying, as attractive as that aluminum CHRA is. Wonder if this is a recent thing...
I was surprised when I read that tread on FB.
I have never had issues with them. I switched to Precision a while back and had a real bad dealing with the,=m
So I switched back to Comp. I starved a turbo on the dyno and instead of repair they sent me a new one.
I have 2 friends with twin oil less ones that have had 0 issues as well. Both 1000RW + cars...

I could never deal with something like that for 3 years .
I would have at least had the car running on a different turbo while fighting the company to make it right .

X10 on the Garrett stuff. They're king when it comes to reliability, not to say they don't break sometimes too. Precision has had their share of horror stories as well, but I've noticed it starting to taper off, or people aren't speaking out loud in the places I listen.
G
I have twin comp 67/67 oilless. They have about 25k miles on them running 8-12 psi, but I have had to ship them back in basically every year for new seals and repack. They covered the cost for this twice basically giving me a new 1yr guarantee each time. It's been over a year since I sent them in so I'm sure they won't cover it again. I've only gotten about 8-10k miles on them before they need repack. No issues with customer service for me, just the pain of having to take the turbos on and off and send them back in twice. I plan to send them back in and have them converted to oiled if they don't rape me too badly on the deal.
I made the switch from Precision and never have looked back. (They still wont return my wrecked 118mm billet wheel for a paper weight.
Been running a pair of Comp CT6X billet wheel triple BB 91's with Tial stainless housings and they've worked flawlessly making 2Krwhp surviving drag week and still feel new for shaft play.
Joe and Ernie are good if you ever have questions and seem to make stuff right if there happen to be problems.

I would never use a comp turbo they are junk, I seen two friends that used comp turbo an personally seen both turbos fail an I mean big time fail, one turbo exploded while boosting up the road, shrapnel took out all his pipe work, filters an coolers all damaged. Other friend of mine just had his for 5minutes an the turbo started making a bad high pitched noise, took the filter out an seen the wheel hitting the compresser housing.
Seen a oil less comp seize up. Guy had all kinds of problems trying to get it repaired.refunded. Etc. Wanted a reliable turbo for remote mount build.
Ended up using a 800$ tnetics n eBay 300$ scavenge pump in the end like I told him too. Comp turbo lasted like 4 month at best. Close to 3k$ turbo.
The tnetics lasted him over,2years n sold the car running w it installed w the eBay oil pump.
He got the comp repaired n ssold it as is.

Same with my two friends, comp turbo did not claim responsible for both turbos, blamed it on no oil supply which there was plenty as the garrett that was on it before had no dramas what so ever. They did not warrant there product, there complete liars an I suggest people to never use there junk turbos. They will tell you that they sell there product world wide an no one has issues with them, what a joke as all it takes is a bit of research to see how junk there turbo is, its all over the internet there complete time bombs.
I see some people in this thread stating they have had good results, and others saying nothing but terrible things.
It's crazy that they can sway that far in either direction (junk or great)
We just finished a street truck 6.0 lq4 s10 with one of their ct43 78/79 tbb turbos. Hopefully we have good results.
