Question for those people in Florida and other parts of the country that get 93...What is the cost of the 93 octane in your areas?

Does anyone know why CA is limited to 91?



We have found that the air to water intercooler is EXTREMELY efficient. As you can imagine dyno pulls put a lot of heat into the system and one of the quickest and simplest examples of an efficient intercooler is how long it takes for the car to cool back down after a hard pull. For example, we have been doing a lot of supercharger installs and custom tuning with the new Camaro's. Those cars are TERRIBLE on heat soak. We will do a pull, then have time to actually get out of the car, walk to the computer, get back in the car, keep on waiting...It's insane before the temperature actually comes back down. With our 370Z and G37 we can do pull after pull after pull with very little down time between runs.

Also, during our development we did insert temperature probes post blower and post intercooler (in some of the prototype/testing photos you will see the yellow wires.) We saw decreases in temperature of well over 100 degrees and at idle the IAT's were within a couple degrees of ambient if I remember correctly.
Do you guys have logs of that -- it would be good to see exactly what charge temps were before and after the IC, especially after sucessive dyno pulls. Not disputing that the cooler is working, just wondering whether there's room for improvement with another heat exchanger. People who will be doing hotlaps might want that as an option...

I would have been surprised if IAT's were much above ambient... It's not boosting at idle, and the water is still pulling heat out of the system... was this finding unexpected?

Also, how many gpm does your water pump flow?

Last question: Any chance you guys will be developing a roots blower kit like you did for the 350?

Can you give us a little more info about your second point?
Yeah, you could always add some puller fans too. Not a bad idea if you plan on tracking it.
