355 ci sbc, with twin t3/t0 super E, 57 trim. have upgraded to twin gtk 550's. maxed out on dyno with 1050 hp and 960 ft/lbs .
what hp and torque increase will i see?
same cam, fuel system, etc
when will the flow maps be available??? gtk series
cheers

I'm confused. Did you max out at those numbers with the GT-K 550s or with the T04E 57 trims?

[ash]

those figures are for the t3/t04 super e 57 trim

[Robert]

Well assuming you are trying to flow out the compressor you should see about 20-30 more lb/min of flow from EACH of the GT-Ks...

[ash]

so... each gtk 550 will flow maxed out at 70-80 lbs/min each??
t3/t04 super E ,57 trim flow 49 lb/min, therefore 20-30 lb's more than that are 70- 80 lb's each???

cheers

My apologies. I saw 57 trim and somehow read 50 trim. The GT-K 61 compressor wheels should flow in the low to mid 6X lb/min range. Sorry about that.

what p2/p1 pressure ratio are they designed to run...max.. for the max lb/s per min?
thanks

I don't have a compressor map for that compressor wheel but in excess of 20 PSI for sure.

finally had run with the twin gtk 550's.
car went 7.4 @ 184 mph
with 2100 feet of air
a/f still way rich at 9.45:1

would real real love to see a MAP of these gtk's so i can get the sweet spot.?????

see what you can find robert????

cheers
