##EDIT## Got some answers, updated thread in case anyone else had same questions.

I've been road racing with an eForce on my LS3 and I've been battling heat issues ever since I've installed it. I've improved my skills over time and that's made it worse since I'm pushing the car harder. I'm aware I should have probably never had a supercharger if I intended to road race, but was new to road racing and even newer to power adders when it got installed. Expensive mistake on my part.

I already have a Dewitts radiator, an external oil cooler, and a power steering oil cooler on a Turn One PS pump. Also running meth injection with AlkyControl. Making about 520RWHP when last dynoed.

I'm not sure there's more I can do to manage heat under the hood. Over the weekend, ambient temps in the high 80's, engine oil was reaching 280ish. After the last session, car turned off and wouldn't start any more. Battery voltage shown 12V. A jump start wouldn't help, so towed the car home. Next morning I put a battery charger on it and it started back up just fine and voltage seems stable. I presume the battery overheated. Probably a good idea to relocate it to the rear.

I think I'm just going to have to give up the supercharger in favor of reliability to keep me on track. On top of the battery issues, the eForce has developed a "whirring" noise that matches the RPMs. An on-site tech at the track used a stethoscope and is confident that one of the rear bearings is on the way out. I've had the SC on there for over 50K miles since installed, so I guess it needs a rebuild. It seems only SuperchargersOnline is the only one who can do it for around $600, please correct me if I'm wrong or there are other alternatives.

My questions are:

1) Is there an easy way to disable the eForce while not completely removing it? Like just take off the belt or something? Will leaving the same tune hurt the engine w/o supercharger running?

##EDIT## Answer is no ^ Either on or off, no in between.

2) What does it take to get the engine back to stock form? What parts do I need? I have no idea where I put the original stock parts after the SC was installed.

##EDIT## Various parts..about $500-$800 worth roughly.

Would appreciate any advice!

 

I don't have any suggestions other than removal. If you are a novice/intermediate level driver and already hitting 280+ oil temp on the track then it will only get worse. This is simply not good for the motor, in particular the bearings. Your coolant temps will likely be too high as well.

What oil are you using? As oil temp goes up, shear goes up, the oil loses shear stability and viscosity goes WAY down which significantly impacts fluid film strength and protection for the bearings. It's called hydrodynamic lubrication. Essentially the oil flow forces the bearing surfaces to ride on a film. As the temp goes up and the viscosity goes down you start to lose the hydrodynamic lubrication effect and the oil loses it's shear stability. This is bad for the motor. Additionally, the oil can shear directly down to the bearing surfaces. You do not want this to happen.

Ditch that blower, which is not suitable for a road course (at least not without spending ALOT more money) and ensure you are using a proper oil viscosity for your usage. You are risking permanent damage with what you are doing.

 

I would be interested in putting your car back to stock and supplying you stock parts for the eforce but you would have to get your car to me Evansville ind.

 

Hehe, thanks Ford1ton but I have a local tech already doing the job here in Dallas, TX.

eForce is coming out and going back to stock very soon.
