Re: SVX Engine cooling "Again & Again"
The flow at high revs needs to be decreased. T

Sorry about the red face. I am on my phone and do not know how I managed to do that . T

Re: SVX Engine cooling "Again & Again"
I hope no one takes any offence - absolutely none is intended.
I replaced the water pump when I did the HG job. I kept the old one.... I tried drilling the impeller - there's no difficulty what so ever. It's very soft. Judging by the ultra short chips it's gray cast iron. I took a 10mm straight cutter and made a hole at the tip of a vane. See photo. The last half a millimeter can be dremmelled off.... didn't want to touch the pump body. Drilling the tips of half of the vanes would be a nice try for someone with a test setup..... or if someone comes up with a better "drilling plan" Tapani |

The difference in heat rejection with a 500+hp engine and a 1000 hp engine is quite different :-) Just a thought.... /T |

Re: SVX Engine cooling "Again & Again"
You guys are all going to hate me for this one, so please accept my apologies at this point :
http://www.fordbarn.com/forum/showth...7106&showall=1 We know the OEM radiator looks flimsy.... that's probably because it's designed for a high coolant flow rate and a low delta T. What if the high performance radiators do actually have a higher heat release capacity, but are designed for a lower flow rate? How many people have actually run into these problems with an absolutely stock arrangement, including all the rad side seals and the engine bay underside plastics and all? Honestly. Tapani |

Re: SVX Engine cooling "Again & Again"
How about decreasing the stock pumps efficiency by drilling / machining and leaving the system as is otherwise...... and then installing a simple electric booster pump for potential low speed overheating situations?
There are plenty of mechanical pumps available for the American iron for high rpm applications (circle track etc). These may well cause low speed overheating issues. Could this work for the track cars? Best of both worlds? http://www.stewartcomponents.net/Mer...Code=ElectPump /T |

Re: SVX Engine cooling "Again & Again"
Guys,
Everybodys opinion is important and wellcome. There a very few "single truths"..... Life is too short and the SVX community way too small ........... Bazza, could you please turn your tone a few click down ? What do you all say - could we all together ask both Tony and Trevor to rejoin (and behave )? Yes? Tapani |

Maybe 10,000 left. Maybe 100 Hot Rodder SVX Guys world Wide. Can't we all just get along? When YT and I were in competition with each other, I could still "TRUST HIM ON RACE DAY" if I had to do something else, work an autocross corner ect. And I knew that He would do the best He could, on My car, on RACE DAY! All ideas are or SHOULD be welcomed. evan the copper intakes...... Can't we all just get along.

I think it would be good to determine a goal for the flowrates we need to achieve, and work from there.

So all you really need to know is what electric pump actually works. If this 1000 bhp car with 150L pump works then it's safe to say it will work on the majority of others. Only difference will be in stock SVX's - it will be doing far less work. This is the 150L/min pump in that EG33 1000 bhp racecar: http://www.daviescraig.com.au/Electr...0-details.aspx Btw: when I tested the EG33 water pump - idle was around 55L/min. I think they must use a big pump to get good flow at idle.... and the peak flow is a negative consequence. Last edited by bazza; 10-03-2013 at 10:38 PM. |

The issue if you go to a smaller pump is you'll very likely over heat in traffic while idling or at low RPM. It's very hard to get a mechanic pump to do both nicely as we know. |
