Boom goes the turbo

Twins

Boom goes the motor... Big Bada Boom.....:eek:

So help me understand this.

According to the Dyno sheet, they achieved 699 ft.lb of Torque?

and this is a stock engine?

It's a built block

There's plenty of Mustang 5.0 and GT 350s using these same turbos in the same location. I even know of a Hellcat using them for making 1200WHP.

There is a reason why back in the early 80's folks hated turbo cars. They went out all the time. Why??? Because they were only oil feed and cooled. In the late 80's most all turbo cars went to liquid cooled center sections for longevity. The only reason Comp offers these turbo's is for ease of installation. Simpler packaging. They have their pitfalls and that is longevity. Comp sucks in customer support also. Warranty, yeah. Out of site, out of warranty.

I've dealt with these type of turbo's in an industry application in the past. And they have been a nightmare.

I am well aware of the changes that have been made to turbo's over the years. I also fully understand the reason why Comp offer's these types of turbos. That doesn't change the fact that a lot of people are using them and that was my point.
Hell even Precision Warranty sucks and have been proven to fail at times ,but everyone still Uses them still because there cheap and make power.





Not doubting what you do for a living. As I stated people are using them time will really tell how reliable these air cooled turbos are. As of right now a crap load of Domestic cars are using them and seem to be happy with them way more of them that us.

It seems to be hit or miss with these turbo's. Wonder how many that failed is a number we will never know about. One of the things I don't like is the fact that the grease that Comp wants you to use is their own brand. You don't know what type of grease it is. The other thing about Comp greased turbo's
I don't like. There is no exit port for the old grease to come out of when injecting new grease. So the old grease has no where to go, gets cooked, and the new grease will just push the old grease into the bearings. Another thing is over greased bearings will fail. Hard to believe but true. Preforming PM's on equipment. They tell you no more then 5 pumps from a grease gun if no exit port. If it has an exit port. Remove the plug. Take a zip-tie and clean out some old grease in the exit port because the grease gets hard. Start to pump grease through the zerk fitting until grease just starts to come out of the exit port. Reinstall plug in exit port.

Its true. You dont hear about the thousands on the road with longevity and no issues, you only hear of the bad ones. Nobody is going to chime in and say "just so everyone knows, my turbo is still doing its job". However, my turbo is still doing its job..lol.

But Rusty brings up a point I have always wondered. I grease my turbo every 5K miles with 5 pumps and have always wonder where the other 30 pumps have gone.

882 miles. That's how long mine lasted.

Mine is at about 40k miles and I grease it every oil change 5-6 pumps I was told by comp that the their grease is water base and is evaporated over time ….I did replace the first turbo for a design flaw with the zerk leaking coolant after about 8k miles

LOL I wonder if Comp knows grease doesn't evaporate :ugh:
