Sent from my Pixel 2 XL using Tapatalk Hi, currently running 10 psi, have ordered a reduction pulley to give it between 5-6 more. After a bit of fiddling with jets and chokes it seems to be running very well. I’ll be fitting a water/methanol injection kit to cool the charge and make the extra boost safe. |

 Hi Chris, looks great. What chokes do you have in the Weber? My VMAXSCART kit was running very rich on cruise with 30mm chokes as supplied in the kit. I have now fitted 34mm chokes and it is running much better and hovers around 10 to 11 AFR when cruising. About 13:1 AFR on idle and 14:1 AFR under power. With the standard pulley I get 5lb boost at 2000 rpm full throttle with a max of 13lb boost at 6500rpm. The car has been dyno Ed a few times and makes almost 90hp ATW,s which gives a fun drive. I am sure you are enjoying your car on the brilliant NZ roads. Cheers |

I am sure you are enjoying your car on the brilliant NZ roads. Cheers I also had 30mm chokes, I changed my idle jet to lower my cruse fuel ratio, that’s the circuit they are responsible for. I fitted 28mm chokes to speed up airflow as I had the dreaded Weber cough. Would bog down when you planted your foot, changed my idle jets for larger ones, which also helped. I was getting 13lb from about 4000rpm but then changed both my head and full exhaust to more free flowing which has bought my boost down. I’ll fix this with a 17% reduction pulley. It’s definitely fun to drive. Got any pictures of yours? Here’s the outside of my Clubby Attachment: EDCE2FB8-D89E-471B-BA5F-15BAE45C92F1.jpeg

This was my original setup with SU which went Ok but had a few small issues due to the length of the inlet pipe. Great for cruising but difficult in stop start traffic

Quote: don't run that for too long, good recipe for melted pistons Been like that for 6 years and still going strong. The AFR does jump around a lot unless idling or cruising |

Idle 13.5-14 :1 afr Cruise 13.5-14.5:1 afr Full load 12-12.5 :1 air fuel ratio This is how mine ended up |
