Finally delivered the parts to Vibration Free today .
Steve is aware what we are doing to this engine so I asked if a Balancer on the front pulley would help compliment other mods. His view was the existing mods would probably cure the vibration probs but there were other benefits if the front balancer was done correctly. Could buy one from the States & mod it or design one from scratch to be correct for this application. Its more expensive but i gave the go ahead to design what we require. It will take around 8 weeks so a delay but will be worth the wait.
Forgot to ask his views on other parts but ive time to spare now.

Just thought of the fact I now require a 4 bar boost gauge can get a 52mm one but its too small any ideas. With the 9180 at the boost levels we will be using i need to keep an eye on Turbo speed so im looking at that. Found one reading up to 200k rpm & an interface to get readings from the EFR sensor.
Before you ask im out of suitable analog inputs on the SM4 so unless i lose an existing function im stuck with other means of keeping a check on Turbo Speed.
Think Mark would like me to change ECU's at this point but its a lot of aggro to gain one more input. I could probably lose Launch Control.
