STILLEN Exhaust & Gen 3 Intake Dynos - 18hp Each!

Denny McLain · 02-20-2009, 06:28 AM

Engine temp sweet spots are pretty much the norm for almost any car and the traditional way people massage the gain numbers. My problem is no way to monitor the water temp which I also consider is the critical parameter vs oil temp. If ya got something, throw it in the box and I'll nuke it right back.

David Vissard (sp? think I have his last name at least close) believes around 170 degrees to be optimal for making power in a traditional small block Chevy. Bob Norwood on the other hand is an old friend and used to preach to me "heat is horsepower." Bob is a god among the Ferrari crowd ,so tell me what these cars like.

With that being said, you are not wrong about the oil temp rising in these cars and we are working on a solution to this. We work very closely with the Nissan engineer's and they told us a few little secrets about some of results from their testing. We are nearly finished with an oil cooler using a very high quality Setrab cooler. It should be ready in the next month or so.

Quick point I've been thinking about and probably a good time to mention it.

Thermostats? Usually the factory installs these for engine longevity and emissions. Are other ones available where the engine is in the range it likes for more power?

The first thing most Corvette guys do is cold air intake, headers, exhaust, and lower temp thermostat.

I want to say that we do all of our dyno testing between 183-187 degrees. I will have to confirm that but those are the numbers that come to mind.

In regards to a thermostat. You bring up a good point and one that is usually addressed by Nismo directly. Your local dealership should be able to help you with that.

I'll call around and look for a 185 thermo. What's stock??

OK so I was right...We do our dyno runs between 183-187 or 185 degrees plus or minus a degree or two haha.
