    Turbo V Engine - Exhaust Manifold Design

    Looking for insight on designing/routing exhaust manifolds for a single turbo on a V6/V8 engine. Lately the trend has been to go with parallel twin turbo but I'm looking to go to a single turbo in this application. Unfortunately, due to the twin turbo trend I'm having trouble finding...

    "Proper" intake air temp (IAT) sensor location....

    I'm having an argument about the proper location of the intake air temp (IAT) sensor with a fellow car fan. I'm sure I'm right but I want to check with you guys to make me feel better (or worse?). Okay, the car in question has an IAT sensor right at the throttle body. The throttle body on...

    Roots SC Intercoolers

    I'm wondering if it would be adviable to try and squeeze an IC between the SC and the intake manifold?? Do drag racers do this or do they just lower the compression to account for these temps?? There's room under the hood but I'm wondering if the IC would really create problems with airflow in...

    Precast Manhole to Footing Connection

    I want to get an idea of what others do in this situation. I have a 25 foot deep (10' ID) precast manhole. We are going to put "doghouses" in the bottom so that it can be placed directly over some existing 30" and 36" pipe. A footing will be poured beneath the existing...

    Calculating Load on Rebar to calculate embedment??

    How does one calculate the load on a rebar that will be embedded into a concrete wall?? I have the Hilti manual so I know how to calculate the embedment but I'm having trouble figuring out the forces applied to the rebar. The element in question is a beam. It's 18" x 18" with two...

    Design of dowel bar depth when going into existing concrete

    I had such good answers on my first question I have a second already. When working with concrete (or masonry) retrofits or repairs, how do you figure the development length for the dowel bars that are inserted into existing concrete?? Is this something that you can only get from the...

    Determining Required Weld Strength

    This looks like a great forum. I have a question as to something I have not encountered in my SHORT career but would like to know. How does one determine the weld strength required when welding a plate (or any other shape) to the bottom flange of a beam? Top flange? Is it the same strength...
