dondesoto Posted November 13, 2005 Author Share Posted November 13, 2005 (edited) Fitted it up on Saturday . As you can see in the pics its got 2 x afm . However only 1 was wired up . As i,m running an apexi safc 2 i tried to add enough signal to compensate for the fact that the afm air speed would be 1/2 what it used to . I had to increase signal to nearly max what the safc can put out . HMMM Sooo switched the input signal to the safc to think it was connected to a q45 90mm afm , as i kinda worked out the air flow speed thru a 90mm t/b would be about the same as 2 x 70 mm inlets . IT WORKED . So the setup consiasts of : 2 x 60 mm rb25 throttle bodies 2 x 70 mm rb25 air flow meters ( only one is wired up , the other is left there to have equal restrictions on both inlets ) apexi safc 2 , input signal set at 1 ( q45 infinity afm 99 mm signal) output signal set at 4 ( rb25 ecu being used ) As a preliminary tune i have put in 20% + at all low throttle settings 27% + at all high throttle settings So far i,m pretty impressed by the way it drives . Seems more responsive and more torque . At a steady 100 kmh the throttle was 14 % now its only 8 % . Will take it out to Willowbank drags test and tune soon as i can . Theres still a few things to tidy up on it but at least its fitted and running well .

thommo Posted November 13, 2005 Share Posted November 13, 2005 awesome to hear that it is up and running, have been following this for a while. are you planning on shielding/venting the pods? would have to be drawing some pretty warm air as they are now.

PHATR32 Posted November 15, 2005 Share Posted November 15, 2005 are you gonna at least run some sort of a cai or a heat sheild over you extractors? i dont think that nice heat will do you any good. looks very very interesting, have you done any work to the interneals? high c/r, cams etc??? steve Link to comment https://www.sau.com.au/forums/topic/84884-2-x-afm-and-2-x-tb/page/3/#findComment-1715612 Share on other sites More sharing options...

Head is unmodified apart from port matching manifolds to head . Yep will be re routing those inlets and shield them .

Nosmo Posted November 15, 2005 Share Posted November 15, 2005 You may have issues with the VVT and high lift cams at such high compression levels. The timing doesnt have to be that far out for the valves to hit the piston crown in the RB25. I was playing around yesterday to see how far out the timing has to be before they make contact... not much! And that vwas with standard cams...

krizza_ca18det Posted November 16, 2005 Share Posted November 16, 2005 That's some awesome work you have done there Don! It sounds like you have it running OK now, but I thought I would throw in my 2c that may or may not help. If you take a look through the SAFC install guide you will see that there is some info on setting up different AFM combos (ie. non factory setups) for both GTR and VG30DETT motors which might help you. The one I'm thinking of is the 2 AFM conversion for the VG, where the 2 AFM voltages are set to be added together before being passed to the ECU. This might be a better way of going about it, as you can use the correct AFM resolution setting (RB25 instead of Q45). Just a thought.

dondesoto Posted November 16, 2005 Author Share Posted November 16, 2005 Willowbank drags last night . Best of 14.4 @ 94.5 mph and a 1.96 60 ft . Am i bit dissapointed in those figures . All the more reason to put it on the dyno and get it sorted properly . Spose i shouldnt complain its the best times i,ve got , previous best 14.7 @ 92 mph .
