housing is 1.05. Thats on pump gas momentum 99 which is pretty much the best we get over here . Ive no plans to run E85 (at the moment ) although the fuel system and injectors could handle it not sure about the turbine speed but will try and check . It isnt running crazy boost by any means (1.6) Im happy with the power . It will run a bigger turbo easily enough but its response and decent torque curve I am looking for . BTW engine is in a stagea .

Thought I would add another dyno result for an RB30 with a 9174 on a 6Boost manifold Basisc Spec. The motor is an OS Giken RB30 with a big valve head and hks step 2 cams . ECU is Link with a custom trigger set up. IT has a single in tank fuel pump with 8mm feuel line using the oem feed as a second return. Power is 654 hp at the hubs at 1.6 bar (23psi I think ) so not on the limit

are the power figures at the flywheel ,hubs or wheels as dont want to post wrong numbers

Just installed mapped and now on the road (in the UK )

i was also about to buy a 9174 but am wondering how quickly the 8474 will be available (if at all ) Plus no one seems to be able to give any meaningful results for the 9174 The car is having other work done so it doest matter if I had to wait a month or so - longer than that and i need to buy a turbo. Have looked at precisions but prefer an EFR as long as i can get the right one. I was told the 8374 would be maxed out , didnt want a 9180 as I dont need to go into orbit so a 9174 seems to fit nicely inbetween .. I was looking at the ext gate 1.05 but only because thats what ive been advised so far Engine is an OS giken 3 litre , with a flowed head and 1 mm o/size valves step 2 hks cams with uparated springs etc manifold is a 6 boost. It has a crank trigger set up running with a link G4 Is a 9174 the right way to go - thats an honest question and would really appreciate feedback because im really not sure what you can get from an 8374 Looking for round 800 bhp (uk at the crank ) . The info on the EFRs s pretty limited in the Uk or put another way nowhere near as good as in Oz
