Hey guys,
I have a fuel injected 509" running a side mount whipple with about 5lbs. of boost. When i bought the boat it was running without a thermistat and still is. I had some work done recently and my mechanic seems to think that I should be running a thermistat. I have been told different things in the past, Should I be running a thermistat on this motor? It never gets above 110 degrees water temp and the oil runs about 210-215 and gets up to about 230 on hard runs but comes right back down. The motor also has a circulating water pump if it makes a differance. Thanks for any help.

I have temp gauges on both water and oil,I'm talking internal thermostat, it is raw water cooled. My mechanic is concerned about the water never getting above 110 but I've been told the whipples need to run cold. Thanks

Removing stat can cause other issues as well, it drops water block pressure, which is critical. You can run a 120deg stat, that would be a good comprimise, but I would still drill 4 5/16" holes in it to help keep spikes down and more consistent to 120deg F. Again, this depends on cals, anything cooler than 140 adds significant amount of fuel.
Thanks,
Dustin

the problem running that cold for the engine anyway is condensation build up in the oil, unless you can get the temp up and stabilized condensation is going to be a issue as well as engine just not making all the H/P as it would at operating temp. I understand with EFI you thay are just trying to "fool" the ecm to keep the air/fuel closer to where it needs to be, but if they can be mapped to run rich enough at temp you will be far better off...Rob
