Getting rid of my Precision 76gts... Looking at a GT91! Well guys, Im building a new motor, and I really want to break that 200mph mark at the mile, so Im ditching the Precision 76gts in search of a GT 91.
Here is a link to the turbo for sale if anyone is interested

So does anyone have any dyno sheets with a GT 91? Jose @ Forced Induction recommended this turbo for me but Im curious to see the kinds of numbers it makes on 400+ cubic inch motors. Im also very interested in spool time as well. So let me know what you got!
Thanks LS1tech!

The wait for the GT-91 was crazy and imho its a bastard turbo. I think if i have problems down the road it might be hard to get anything for it and I also anticipate a minimum of 3 month turnaround. It does seem to build boost extremely fast but I may be over running my stall a bit. I'm hoping to have dyno+track times (7000+DA) soon.

and you just mean that because its not similar to other turbo's (component wise)? I would think Jose could rebuild it for you if you ever had problems....

I'm sure he would and that would be fine just I know to triple the time frame with them. Not saying there lazy or slow- just seem plagued with back order parts for the Gt-91. I'm not 100% sure but I think nobody has any parts for this turbo in stock nor carry's them other than forcedinductions. Not saying I wouldn't buy another 91 but its something to think about.
