Hi guys, hope all is well!
copy/paste from norotors to get this caught up.
pump hanger has landed but i am missing a spacer that mounts the pumps parallel to eachother. made a jegs order with everything i need for this and the power steering setup so hopefully next weekend i can get this thing back together. I have mounted the new Radium fuel filter above the rear diff and it appears that my current fuel lines will work.
Pulled the intake off to install this fuel pulse damper and also found/fixed an oil leak from the CMP sensor. Intake gasket was questionable so i installed a sikky thermalnator phenolic intake gasket which claims to reduce IATs by 25-35*.
Quick update on this thing, i have driven it after replacing the pump and my low fuel pressure issues are resolved of course. However, i am having issues with my aeromotive FPR (which has been having issues from the start) and will be replacing it for a fuellab unit. First issue is with the dual pumps running at idle and off boost, there is too much flow for the aeromotive to handle and it will not go below 50PSI. I know the return port on these is very small and this is an older model, but the regulator also does not pull 1:1 boost reference, nor does it hold pressure once the key is off. I have been reading a lot of horror stories with these units and their quality so i will just replace it and stage my pumps to keep fuel temps down. Other than that, i did beat on it for a bit one day and it is getting pretty quick. I will upload some pulls to youtube later.

Custom ordered a fuellab FPR with the large seat and out of the box my fuel pressure was 35 PSI with both pumps running. Much better compared to the aeromotive which could not drop below 50PSI with the screw turned all the way out. I also pulled the aeromotive apart and the seat looked to be updated from the pictures i found and it was cut correctly however still did not increase FP 1:1 with boost. Fuel pressure is now rock steady and barely fluctuates 1PSI throughout the powerband and raises 1:1 also. Very happy with the fuel lab setup coupled with the radium pulse damper.
With that solved i was able to do some WOT pulls but found i was hitting 19PSI running 15PSI wastegate springs (boost controller not on yet). Swapped down to some 10PSI springs and now im at 13.5PSI which is right at the 14PSI target for my current tune revision. Datalogs sent away and waiting on another revision now. Also got power steering hooked up finally and the car is much more enjoyable to drive. This setup is the stock VVTI PS pump with the solenoid disconnected, excessive manufacturing HP line, -6 conversion fitting and -6 return line, and -10 suction line using a chase bays baffled reservoir. The steering feels good and is not too light at speed yet manageable during low speed turning. From what i remember it is slightly less assist than the OEM steering setup.
Got an alignment done. We only adjusted toe and man what a difference it made. My front had like 2* toe in on the right side. Currently at -5* camber and 1/16” toe in on the front and -2* camber/ 0 toe rear. Car is 10x more smooth and much more enjoyable to drive at speed without the wheel being twitchy and jerking through bumps.
The dallas cars & coffee was having their last event at the current venue so i drove the car the 60 mile round trip. Great turnout at the show and saw some big money hyper cars.
And street tuning for pumpgas is 95% complete, currently at 16PSI and will stop at 18PSI for pump93. Once it warms back up we will continue with E85. You are not allowed to view links.
