Adrian,

I thought it might have been posted here, but in testing FP saw anywhere from 2-6 lb/min mass increase depending on inlet temp.

 

There isnt one...only the housing itself.

 

Dam, I wish I knew about this when I had my turbo out

 

backing plate is different. doesnt bolt up

 

He was asking about the wheel size if I am not mistaken... <3

 

the compressor wheel is bigger on a 9 than a 8 i'm sure

 

Wheels are the same, only the housings/back plates are different sizes...

 

oh right. dam. cast up some ally covers we can convert our 8 turbo's to 9's
i was going to sell the 8 turbo i just removed but may aswel keep as a spare if my ix dies i can just fit the ix cover get it rebalanced and jobs a good un. feasible?

 

From what I have heard the bearing section in the 9 turbo is much more robust alowing it to survive at the higher loads tat the larger wheels produce. I would say just get a ix turbo if you are interested in that rather than trying to reinvent the wheel.

 

was that to me batty? the wheels aren't bigger apparently! ?
yes i have a ix but if the ix is nothing more than a 8 with a cover surely the cover will fit making a 8 a 9? your prob right tho too much hassle

 

thats not true. the bearing section is identical.
reliability between 8 or 9 turbo is the same.

 

Thats is interesting. If that is the case I wonder why FP didnt make a larger cover for the 8 and convert 8 turbos to the newer HTA turbos? Is the major diameter of the HTA compressor wheels too larger to machine the backplate on an 8 turbo?

 

More than likely, yes.

 

I just hope they have the stock IX FAP cover on sale for ~$75 like they did for the bbk one day...

 

$200 for the gains you will see is well worth the money IMHO.
