Hi-Torque Member 24 Member For: 18y 1m 25d Posted 21/04/08 12:44 AM Share Posted 21/04/08 12:44 AM It would be great to see the timing map, and data logging for inlet temps30psi would suggest she's out of her effiency range, maybe a larger exhaust housing will give better gainsWe have been logging this car and as the dyno chart shows we are getting high intake temps due to maxing the turbo out therefore pulling timing at high rpm on 27psi approx 700rwhp the car draws a perfect powercurve I will post up one of the 600 pulp 20psi. Don't worry guys new turbo on order allready. Link to comment Share on other sites More sharing options...

Hi-Torque Member 24 Member For: 18y 1m 25d Posted 21/04/08 10:58 PM Share Posted 21/04/08 10:58 PM Brillant turbo the GT-K850 would be perfect for a replacement turbo on the XR chasing aroung the 550rwhp , The turbo is very well made the only let down being it doesn't have water cooling.kent Link to comment Share on other sites More sharing options...

groper Member 611 Member For: 17y 9m 4d Posted 22/04/08 02:16 AM Share Posted 22/04/08 02:16 AM (edited) why would you bother with an 850gtk for 550rwhp when the factory turbo will do it? mine makes 530rwhp on 18psi... surely you could squeese a bit more than 550 out of an 850gtk???
