I think the problem is extenuated by the extra force required to turn the CAM's against the stiffer valve springs. You can see the belt "whipping" whilst the engine is running... yes, the Tensioner was checked and yes it was adjusted correctly.
You were right Rob... run out of fuel on 433kw on 19psi ... really thought it would be good for a bit more than that. When I say run out, I mean there was nothing coming out of the return to the tank. The injectors are using everything the pump can supply. The Crank Triggering System works nicely with rock steady timing, will be able to take full advantage of this when we finish the tune after the fuel pump issue is sorted.
No, we caught it before leaning out occurred. What alerted us to the problem was having to really "ramp" up the fuel delivery via the fuel map... got up to 90% duty cycle on 800 cc injectors... bit of a "red" flag. Is already a twin entry setup, will add an additional pump and considering running an-6 ( 10mm ) fuel line from the pump/s... A short video of one run http://youtu.be/nR31tFQ25U0
From memory ( forgot to get the printout ) 10psi was at 4000rpm and the 19psi at 4700. Max Torque is @ 4888 and max Power is @ 6965 ... 330kw by 5000rpm As a start I am pretty pleased with the spool, I am sure with a bit of CAM timing and boost control adjustment this could be improved.
Thats bloody good spoolup for those turbos, would be amazing with Forced Performance HTA compressors.
See how steady the timing is after the Crank Triggering Setup... unfortunately I haven't got a "before" shoot but I can assure you it jumping around by 1-2 deg at idle and more as the revs rose. http://s67.photobucket.com/user/lostsoulz32/media/video-2013-11-02-16-57-41.mp4.html
thats awesome! I would be very interested to see how much more timing you can run using the steady crank sensor vs cam??
Thanks, If you have a look at the Dyno Graph you will see the orange and pink lines at 5000rpm, the pink line is where he put a bit of timing in (don't know how much) before the fuel issue was noticed. Listening to the car on the dyno, she sounds like she really wants to make more power... I am currently installing a larger fuel supply line from the Tank and will slot a Walbro 400lph next the the Aeromotive pump. Going to be interesting
Forgot I hadn't posted the Dyno Graph... As can seen there is a bit of "witch-craft" to be performed to smooth out the humps and bumps.
Update ... Have also fitted a water injection system, I am undecided as yet as whether I ran straight water or a water/methanol mix. Currently set to have the water start at 8 psi ... my understanding is that the amount of water gradually increases until 24psi, at this point there is 41Lph being injected. Tuning/Dyno result to follow ... hopefully not too far away.
