Hello,
I have recently completed my RCR GT40 and I'm trying to improve it's driveability. I have the RCR pedal box which has a Lokar throttle cable connected to a Borla 8 stack injection. Two issues:
1) The Borla intake operates fine when first started but when things warm up to operating temp it tends to hang up when returning to idle, causing the idle to stay around 1800 rpm and then will slowly back down close to normal after a long wait. If I "blip" the pedal it will return to normal idle immediately. I have checked all of the linkage for binding and have loosened all the throttle plates to re-center them but the problem persists. I'm pretty certain it isnt a hang up in the cable. I have also rerouted the cable to make sure all curves in the cable are larger than the cable specs. Does anyone have any experience with this issue...a possible hidden gremlin in the Borla intake?
2) The throttle is hard to press, giving it poor "feel" when using the clutch. The Borla intake has the stock springs at each throttle body and has no additional return springs. I'm thinking the geometry of the RCR throttle pedal doesn't have the adequate leverage needed to easily operate this intake. Again, I have inspected and lubricated the cable and it operates without friction. Has anyone had a similar issue? Maybe a mod to the throttle pedal to give it more leverage?
Thanks for throwing in!
