Ozy,
I too am very interested to hear your answers to these questions. YS and I have been playing around with all kinds of different mods trying to find what works best together, etc... In addition, what electronics are you using (VAFC or other) and what year is your car? And do your dyno sheets map A/F and/or boost? Also, would you mind listing your mods? Thanks a lot!

Hi
I have the Vortech that also peaks at about 7 psi. I am seeing 330 at the flywheel/ 195 torque but the fueling could be improved beyond the FMU and VAFC. I am also seeing around 14:1 between 6000 and 7500 with about 12.5:1 air fuel at 8800 rpm - I would rather see low 12/ high 11 for safety at this point.
Do you have any data on air:fuel that you can share? This would help other owners of SC facing fueling issues - to compare notes. I can post pdf files of my air:fuel on dyno runs if that helps .

Don't worry - my baby is siting in the garage only coming out for dyno runs. If you look at some of the other postings for SC owners you will see some similar peaks in air:fuel. I'm getting mine tuned with a Greddy to deal with these peaks and improve the overall curve - hence my interest in sharing data with others.
On the engine power - yes it uses the spin-down to make the calculation

Could you tell me where you got your smaller pulley, could it be made in a 4.1 size or just 4.25? Also, approx cost
Also could you tell me where you got your Tial blow off valve and about how much it would cost?
Thanks
James
