New TURBO what do you think?

Are you going to put a wastegate on it? If not, watch it, you may be able to over speed that poor thing...
 
Innovative didn't have an overall great repuatation, two of the guys left and now run Comp Turbo. I wouldn't necessarily be concerned about overspeeding the P-trim turbine, the quill shaft is small and tends to not handle the pressures associated with a diesel engine.

When I start mocking it up on the truck Im going to look at putting a spacer with an external waste gate on but I need to see what it looks like because they are about 2" tall.

I think most of the reputation problem came from when they closed the had alot of peoples stuff and they never gave it back.But from what I understand when they were doing business as usual they had stuff equivalent to precision and Garrett. It is dual ceramic ball bearing. and water cooled I hope it will be alright
Uh - oh that doesn't sound good .I have talked to the guys at comp turbo, before i bought it. I was afraid i couldn't get it serviced but they said no problem. What are the diameters of an hx35 shaft and some of the fat shaft turbos? I will measure this one next time I take it apart.

I found this list on many different searches. I know it cant be true of all ar sizes because they would be different for different frame sizes. but i hope its not accurate for a t3 cause thats a 11cm housing for me and thats to small.

I found this list but i don't know if it is correct:
6 cm2 = 0.41 A/R
7 cm2 = 0.49 A/R
8 cm2 = 0.57 A/R
9 cm2 = 0.65 A/R
10 cm2 = 0.73 A/R
11 cm2 = 0.81 A/R
12 cm2 = 0.89 A/R
14 cm2 = 0.97 A/R
15 cm2 = 1.05 A/R
16 cm2 = 1.13 A/R
17 cm2 = 1.29 A/R
19 cm2 = 1.37 A/R


:eek:

There is no way that is accurate...
 
a/r is a ratio between volute size and distance from center, not volume.....
 
There has to be a way to compare MY .82 ar to cm2 . at least that way I can compare to what everyone else on here is using. Anybody have any ideas.
 
alot of that paper math doesnt always equal the performance your looking for

bolt it up, try it out, then you will have first hand knowledge how it will perform....
 
Why do people expect us to tell them every single thing about a turbo they bought cheap hoping it would work, AFTER they buy it. You're lucky we didn't tell you that you're Fukked and it's a piece of crap.

Why do you care what size housing it is in cm^2?? Smokem told you it was bigger than a 14cm Borg Warner, what else do you need to know?

That's how I've done it...paper works to get you in the ballpark...experience is what finishes the job.

i guess other than reading you may also need some common sense to be able to interpret the information
 
And those table's are in no way accurate....the wheel size, housing size, etc, all figure in to it....

Then you stuff a housing from one turbine size onto a different one, and it's all out the window again!

ya the table is no good, i was going to copy some good post's forrest made over there, but i figured he may learn more by reading all of them



a/r stands for area by radius. a/r is a ratio, cm is a volume.........
