I plan to add a vented hood help with air flow through the engine bay. I am just trying to get a feel since I have seen it and they said they like and it works great. my car mostly drives on the track. It is not a DD and will never be one. I appreciate all your guys input and opinions on this topic. thanks

Bear with me because this is going to sound like a big sales pitch and I apologize in advance for that, however, I hope that by the time I'm done you will see exactly what I'm saying and recognize that this is only intended to offer information and be helpful instead of just sell our wares.

1) Additional cooling: As everyone knows additional cooling is going to be extremely important on these cars and we have a few ideas on how to solve this.

STILLEN Front fascia- As it has already been mentioned the STILLEN front fascia increases the front grill opening substantially and also offers additional openings for accessory coolers such as oil coolers. On our car, we're running the STILLEN race cooler and the STILLEN street cooler! I have flogged the crap out of that car and it is very hard to overheat the engine oil with this setup! Basically, we retain the standard mounting location of the race cooler and the secondary oil cooler mounts on the drivers side vent opening. You will want to cut holes in your fender liners to allow the heat to escape after going through the cooler but that is very easy to do. On the driver's side vent opening we plan on fabricating a secondary heat exchanger as well. So the coolant for the intercooler will travel through the main heat exchanger mounted out front, then through the secondary cooler mounted in the fascia opening, then back up to the manifold. Again, you will need/want to cut some holes in the fenders to allow the hot air to vent out but that's really simple.

2) Secondary cooling solutions: When I get a chance (it will take awhile) I am hoping to develop a system that will cool the coolant down without any input from the driver. It should be pretty simple and if done correctly will work very well. My only concern is that it might not be cheap. My estimated price is around a grand but I'm not 100% sure about that yet...Could be more, could be less...Won't know until it's completed.

We definitely plan on offering upgrades for the supercharger system. Some will be minor and some will be major but we do plan on continuing to push the capabilities of this system!

Great info and thanks. Chris and I will keep an eye for it and we have some plans to counter the heat that I know I will be generating. My car only has one position WOT so heat is a major concern for me. Interested in all these cooling feature and I am considering the fasia.

^ Cool.

I am interested in that extra cooler for the IC core too. Thinking about fans for both the IC and the oil cooler as well as the O2 Sprayer.

Can you give us a little more info about your second point?

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? :confused:

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? :excited:

Yeah, you could always add some puller fans too. Not a bad idea if you plan on tracking it.

We have 91 exclusively in Utah because of our elevation. Being 4500+ ft up, we can get away with it since all engines up here have greater detonation resistance with the lower air density.

For California, I think it has something to do with a combination of the oil companies and CARB regulations. Apparently it's pretty difficult to make a 93 octane gasoline that meets all of your emissions requirements (including oxygenation). Only one company - Unocal - had a process to produce a 92 octane fuel for California's most recent requirements. Unocal is apparently defunct now, so nobody is licensing that process any more. Cost is the major factor, however. The price of 93 would be just that much more on top of your already outrageous gas prices.

This is just paraphrased on what I knew before and what I just read... could just be conjecture on somebody's behalf, but it sounds logical. :tup:
