datzenmike Posted November 14, 2014 Report Share Posted November 14, 2014 You air inlet is sucking hot rad air from under the hood. Wouldn't it make more sense to draw it from outside? The IC has to work even harder to drop the temp to barely ambient. Not understanding the second stage IC. First how does air circulate through it? does it have an electric fan? Second it's bathed in hot rad air so it's actually going to warm the air from the front IC. OR... is there a hood inlet and the fan sucks air in??? 1 Quote Link to comment
RMP&O Posted November 15, 2014 Report Share Posted November 15, 2014 You air inlet is sucking hot rad air from under the hood. Wouldn't it make more sense to draw it from outside? The IC has to work even harder to drop the temp to barely ambient. Not understanding the second stage IC. First how does air circulate through it? does it have an electric fan? Second it's bathed in hot rad air so it's actually going to warm the air from the front IC. OR... is there a hood inlet and the fan sucks air in??? Don't have a hood so no. It is a temp set up in this engine bay and truck. The truck pictured that the engine is in was the donor truck for the engine build. When the engine is sitting in it's final resting place it will be using a snorkel for air intake. The path of air is air intake to turbo to top mount I/C to super charger to front mount I/C to manifold. So after the turbo it is cooled by the top mount and after the S/C right before going into the manifold it passes through the front mount. During initial testing we were getting a solid 8*c drop across the top mount and iirc 15*+c across the front mount. I hear ya about heat sink but from our tests air temps dropped considerably over the I/C's. I didn't build the engine. When it is in it's final resting place both the top mount I/C and the oil cooler will have hood scoops. The stock fan pulls mad air, much more then we could move with an electric fan. See other videos on youtube of the engine showing how much air pull with the stock fan and with the electric on. However, when going super slow off-road at low rpms we wanted to be able to move some more air across the front mount I/C. So we put a puller fan in front of the rad between the rad and I/C. High EGT's were a major concern in this build. While I don't have the engine running daily yet so no EGT gauge every SD33T I know of with an I/C EGTs are fairly low. I am interested t find out where I am with EGT's but that will have to wait awhile. I have not ran this engine out on the road, just around the property here where I live. But driving it in 4wd low up through 4th gear, rpms up to 2500 for upwards of an hour on the property. Well, I can touch the turbo and it is cool enough not to burn my hand. The oil cooler will barely even feel warm. So for all my initial tests, this engine runs very cool in all aspects. Cheers Quote Link to comment

DaBlist Posted November 21, 2014 Report Share Posted November 21, 2014 I friend torn down his 911 engine just do to so many oil leaks. There are like 75 different seams and places that can leak oil to the outside and many are under pressure like the chain tensioners are external. Block is two halves with no gasket, cylinders to the block... Quote Link to comment
paradime Posted November 22, 2014 Report Share Posted November 22, 2014 Blind people need engine porn too. Agreed, and I should know, I am visually impaired. Smoke, I think this may be the N/A advantage you've been looking for. Must crank to 11, Oh and get a rag for clean up. Quote Link to comment

datzenmike Posted November 23, 2014 Report Share Posted November 23, 2014 Perhaps too esoteric for me. S30 between 5K and 7K makes me wet. Quote Link to comment
