Re: 11:1 CR Race/Street Engine build
Harvey I agree with you. If we are to get the performance out of the motors we are aiming for then its one of the issues we need to gett our head around. If as Tom mentioned the wire wasn't shielded properly and the signal get weak it would be a reciept for failure.
By the way I have posted photos of the buggy here.

I think if the pump is replaced with an electric pump the flow will always match the temp, so it can’t produce higher pressures in the block. Harvey.

Re: 11:1 CR Race/Street Engine build
Very interesting theory. Let's say that Tom found a way to fix or go around those weak spots, and a way was found to parallel the flow of water to its temperature at different conditions... let's say while racing, the maximum flow allowable by the engine block is reached and the water keeps overheating... what is the solution here?

Increase the block's ability to flow. Which is partially why I am adding the aux line to the cylinder heads and also why the X-over ontop of the engine will also be looked into Tom |

Re: 11:1 CR Race/Street Engine build
Appreciate if you can post pictures of this setup. Also what are the weak points that you saw in the block?

Re: 11:1 CR Race/Street Engine build
Frank Aragona has a billet steel crank in his EG33 drag car. He told me the stock crankshaft started really flexing like crazy at about 10,500 rpms. Up to 9500 it was very stable. IIRC, Rigoli also went this route.

I hope by addind auxiliary lines to the back of the cylinder heads we can assist in keeping this stagnation to a minimum and thus assist in the overheating issue. The X-over have a larger volume will assist in maintaining a desirable velocity throughout the engine instead of bottling it all up on the left side of the engine. Tom |

Re: 11:1 CR Race/Street Engine build
Tom its worth pointing in support of you idea that the back cyclinder on the AC compressor side is the one that overheats from what the buggy guys told me.

Re: 11:1 CR Race/Street Engine build
Rally Bob,
I followed up about Tom's point re the Cam sensor and the buggy guy said he will check the wiring but thinks its okay. My question to you is do you know or can you find out what cam & crank sensors the drag guys are using. If they can get the engine to rev to 10,000 then we should be okay. I just wonder if our cam sensors are not good enough past 6,500. Tony

Re: 11:1 CR Race/Street Engine build
I thought Bob ment engine RPM at 10,000?

Re: 11:1 CR Race/Street Engine build
I would imagine that the stock sensor with the proper air gap would be capable. The stock ignition system, I do not know

Re: 11:1 CR Race/Street Engine build
The signal from these inductive sensors, is a sine wave that is prone to interference. The wiring from them has to be shielded, and the shield has to have a good ground to prevent it.
