And I am not shure what your looking for with that pipe header configuration do you have the stock header if so put that on there. I run racers edge heat shield tape on all my bodies just because I spend alot of money getting them airbrushed its safe and I like that.
Hello again,
I've just meassured the shims on my engine, and actualy there are 2 shims on it. One (aluminum) with 0,4 and other (cooper) with 0,1mm thick. So it means I'm using 0,5mm + 0,3mm.
Related to the header I'm using, I have the GO header, but due to the lengh of it, the pipe is so close to the body, making worst my melting problem. That is the reason why I'm using the OS shorter one.
My engine has almost 2 galons on it, and there is no more pinch on the TDC.
So please, don't worry about the lack of boton end performance. This is part of my setup to a very loose track.
My problem is the pipe temperature, that is been so hot and melting the body.
Should I take away another shim ? Perhaps 0,4mm + 0,3mm is gona be fine ?
Can you please help me with this issue ?
Thank you in advance.
