No one at STM runs or has ran a Comp turbo so I realistically don't see them recommending or even having any input on one. Who do you claim said great things about them? This type of post can be misleading.

 

I spoke with Chris Wubbenhorst (Owner of Cavalli Turbos) via email, I don't want to share the entire Email because I don't know if he would want me to or not, but to sum it all up.

Then I asked him about some flow charts and the efficiencies of both the stage 1 and stage 2 turbos. He said the stage 1 would be good up to about 450-475whp, with the stage 2 good beyond that.

They don't have any solid numbers right now because they haven't tested a whole bunch. Supposedly they are bringing in a tuner in a few weeks to tune and dyno some cars with the turbos on them.

Oh, and he said the links on the site that keep timing out when you click on them, they aren't supposed to be there yet. That's to redirect you to the shopping cart in the future.

I should hear back from him soon regarding the flow charts, I'll check with him and make sure it's alright to share them with you guys if I get any.

That's all I got for now

hey guys, i dont generally like leaving bad feedback but here's why.

over the last 2-3 years i've bought many compturbos (for a another jdm platform). the first few units (tripple bb) were fine and even i have one in my current drag car (toyota) and it working fine. but 3 turbos i last purchased didnt last 1000-1500miles before blowing smoke. one motor was just being run in, so hardly any boost. got in touch with compturbo as they were under warranty and i shipped the chra's to them.

after what took a long time and lot of international phone calls from me to them, i finally got them back. put them on and two failed again in less than 1000 miles. the third remaining compturbo is not back on the car yet. so i have no idea if that would go kaput too. during this entire time compturbo's customer service was probably the worst i've ever had to deal with. they just wouldnt provide me with a tear down report etc. they asked me to send them back to them for a 2nd time, but i just cut my losses and decided never to buy compturbo again. the FEDEX bills alone the first time to ship to usa and have it shipped back to my country was around $600-700.

while this was going on i googled compturbo and found many forum posts about their bad service and products failing etc. i would much rather go with a more grounded turbo company...

 

I can 100% guarantee that EVERY company that manufactures turbos is going to have problems here and there. After all, turbo's aren't meant to be used and abused for extended periods of time, or used for 200k miles. If you get 200k miles out of a turbo, you did a very good job.

What was the reason behind the turbo blowing smoke? Blown seals? Good thing about Comp turbo's is that they are rebuild-able. Never rebuilt a turbo before? Give it a try, it's rather easy and can save you on shipping back and forth to/from the company.

I have ran several different turbos on several different cars. I have a FP Green (OG) on my car right now that overheats, I had a Garrett GT28RS on a SR20DET prior to my Evo that had CHRA (bearing) problems, I had a stock Garrett T25 on another SR20DET that blew seals (yes, plural) at stock boost levels.

Basically..... What I'm saying is, I don't really listen to other people's reviews a whole lot until there is substantial evidence to back it up. Not calling anyone a liar, but people tend to exaggerate things. I've had my fair share of bad customer service and bad turbos, but if I had to go back and do it again.... It wouldn't matter. Regardless of what kind of turbo is made, people will have problems with them no matter what. How many FP turbos do you think are sent back to FP to be rebuilt? What about Garrett? What about Precision? What about Blouch? What about Holset/Cummins? They all have their problems, but they all have their good working turbos too.

Just my .02

 

fair enough, i understand that every manufacturer will have issues. but i've also used garrets for over 10 years on builds and they have proven far more reliable (in my personal experience). also compturbos customer service is terrible. after doing back and forth with the above issue with the 3 turbos, they wouldn't reply emails..neither justin nor joe would even come to the phone. once they had my money they were not really interested in sorting our any issues.

as for the turbo going...they just wouldn't tell me why..i asked several time for a tear down report, but i did not get one. as mention earlier all 3 turbos were purchased and installed withing 2 weeks and failed under 1000-1500miles. as for the car it was on ...oil restrictor used was one supplied by compturbo, oil pressure was good, oil lines/returns were all up to spec. the cars even had very good breather systems to eliminate crank pressure (these were on toyotas..not a mistu). neither of the turbos saw over 15psi. they blew before we had a chance to wind the boost up to the 30-35psi range we normally run.

i lost around $5K for those 3 turbos not counting the shipping costs etc. through all this if their customer service had been better..i would still purchase from them. but they just didnt care. other companies have much better service. specially for us overseas customers.

again this is just my personal experience with them guys..

 

Bumpin this thread. I contacted Comp turbo/Cavalli Turbo, a few specs I was told. Bearings are special made in Germany, turbine and compressor housings are made in USA, they are not Mitsu MHI, but are 12-15% larger than the MHI housing. Flow rates are 56 lb/min for the stage 1. On there test mule evo they made 450 hp at 28 psi on a mix of c16/93. 18 month warranty. No outsourced Asian parts is what he stressed. The specs seem pretty good. This seems to be similar in flow to a bbk full. It also uses all the stock oil and water lines. Someone please get one and test it out.

 

A cousin of mine is putting one on for a friend of his. He is doing some Fab work of some kind. I will try and see if I can talk to this guy and get him to post here.

 

That flow rate of 56 lb/min is more like a bbk-b , I think the bbk- full is more like 49 lb/min. Somebody correct me if I'm wrong.

 

I was thinking the same thing, but if you compare dyno numbers to the quoted number from comp they seem to be very close in output.

 

Ya, I still get confused with their turbo lineup.

 

2300 bucks... ouch... anyone bit that bullet yet?

 

I almost placed an order for one, but I need to address other concerns before I track the evo again.

 

Yeah im not testing a 2300 $ turbo.

I have tested Turbo Labs which made me 490 WHP at 34 PSI on a slight up hill. Want to text their other stuff on an an Evo X. This is worth testing because its only 600 bucks with a core.

I dont mind paying 2300 for a proven FP or Map turbo but for some company that is new with Evo turbo. GTFO!

 

saw this online. http://compturbo.com/spotlights/evo-4-9-replacement

hopefully these perform well. Always good to have other options.

 

so far they perform like lead weights in the spool department for the evo x version.
