Currently I run the standard drag gen 3 turbo. I want to support 400whp efficently. First question, can it be done with that turbo. Second, if I upgrade, which would be best. I am leaning towards a t3/60-1 w/.48a/r for faster spool, or the same turbo with .63a/r. Or, a small upgrade from mine, a t3/t04e 60 trim .63a/r?? Now if I go with the T3 I need a new manifold also. If I stay with the to4e range I can use the drag manifold and save some $$.

 

I have a turbonetics t3/to4e and it spools up pretty quick. That is the quickest turbo I have had experience with.

 

why would you need a new manifold? a T3 and a T3/T04e both the T3 flange right?

 

yes....

 

can the drag turbo be efficent up to 400whp? I live in utah at high elevation I know that plays a part in a turbos effieceny..

 

If you want to upgrade to a better turbo, run the 60 trim if you are worried about spool up time. If you arent, and you like traction run the 60-1 t3 .63a/r. You will still get full boost around 5500rpm, and it will pull till 8,500rpm. Lag=traction. Beware that you must run minimum of 12lbs of boost to make the 60-1 efficient. It does flow 60lbs/min compared to the 60 trim which flows 53 lb/min, but in this case its not efficient at all below 12lbs and you are better off going with the 60 trim.

 

Will the 60-1 .63 be able to handle 20-25 psi or is this to much for that turbo? Will it pull to 9000 rpm?

 

I have thought of the whole lag thing helping out with traction. The 60 trim/.82 ar has more lag than the 60-1 from what I have heard..I wonder if it would be best to stick with my turbo and get a more efficent intercooler??
