This week we had our third project presentation and I am pleased to say that it went well. We were able to present the class with tangible practical results which lets be honest they were waiting for. We proved to the class that our project woks as a concept. However we had done pressure calculation from our results and found out that the maximum pressure achieved by us was 0.5 PSI. This is disappointing figure as we were expecting figures of about 30 - 60 PSI.
Doing some thinking I realized that we had used our exhaust flap and blocked the end of the exhaust (as we couldn't really block it behind the turbo). Now exhaust pressure behind the turbo would be much higher compared to the pressure at the end of the exhaust. This theory is based on pressure drops. Since the exhaust air travels through a series of bends and restrictions (CAT and Mufflers) exhaust pressure drops. I still believe that if we were to block the exhaust behind the turbo we would achieve the high pressure readings which we are looking for.
