Re: Engine temp rises when I get to cruise speed
Quote from the very first post on this thread:
" I've been trying to cool my car down a little for the past couple of months. When it's 50-60 degrees outside it's not a concern, but as we get into summer here in Jersey things really heat up. It seems that after I installed the radiator the problems started. I had a cheap Ebay aluminum P.O.S. it there last summer and I had no problems" Now why in the world is this problem so damned hard to understand and correct ? Terry

Fans matter at ~40mph and lower. You are telling me you will definitely not do this. You removed a SPAL pusher and put a cooling components puller fan in. We recommend SPAL fans because we believe their products are superior to all others on the market. I would not have mounted the puller fan and shroud but since you spent considerable money, I suggest you remove the shroud and you may derive benefit from it. Its four bolts. I am not advocating the removal of fans. I am also not supportive of your coolant changes. There are plenty of good suggestions on this forum but as my particular suggestions do not seem of value to you I am at a loss. |

Let’s stop the bs and either supply a radiator that will cool correctly or tell Joe you will not help him. I have read every comment on here. If straight water won’t cool you have a problem. If you need fans at cruise speed you have a problem. There are hundreds of blown flattys similar to Joe’s that run cool we all know HP = BTUs but even blown these engines in street form do no make excess BTUs. Let’s correct the root cause and get on with our fun lives. Thanks. Cheers Tony. |

I would want a system that delivers a temperature between 180 and 190 - and NOT over 195 on a hot day (on the highway) - with your particular 7 lb cap. Yes, you have a pressurized radiator - and that raises the boiling point, but it doesn't do anything about the total heat soak of the coolant. Also, the hotter the engine, the easier it is to detonate it - and with a blown motor, this is even more of an issue. Last edited by Bored&Stroked; 07-12-2022 at 06:48 PM. |

Re: Engine temp rises when I get to cruise speed
I always recommend the largest core that fits. I always advocate pullers over pushers. There is no compelling reason anyone would elect for a thinner core except (1) the incremental cost e.g. $100 or (2) insufficient space. The fact that a pusher fan was used suggests we were told there was insufficient space. I did not measure the space. It was not my recommendation to build a thinner radiator; “expert” or otherwise.

As the expert you should have offered or even insisted that I go with a larger core. I told you, as per my above email, that I had a pusher because of no room for a puller. That DOES NOT say I don't have room for a larger core I have over 15K in the set up and building of this motor. Do you think $100 would scare me away from a larger core. I always did things in excess when I put this car together I'm not sure what you're trying to say, but it sounds like you're say I didn't want to go for the extra money for the larger core. I call B.S. sorry |

Re: Engine temp rises when I get to cruise speed
One more comment. A stock 36 radiator has 4 rows of tubes. Why would you build any less in a stock style radiator? Please answer that. I believe a correct stock radiator may cool this engine. Probably 85% of Joes driving produces near stock Mercury HP.

We also increase the fin density for more copper and heat exchange points Ford began doing this in 1932 and again in 1939. You are probably right, Joe should buy a stock radiator. |

Re: Engine temp rises when I get to cruise speed
Joe: Do the removal of the fan/shroud test - then you'll know if the radiator can handle the engine heat at cruise speed. I'd richen the carb first - test it with that, then pull the fan/shroud and test again. Once you see the results, you'll have a good idea as to if you have "enough radiator" for the application.
If you don't then I'd suggest a conversation with Lee to come up with a solution you can both live with . . . versus a stalemate and exploring other vendors. If this doesn't work, then you at least tried. Best of luck, Dale |

I'm more interested in a gotcha scenario.
Big respect for responding. For me anyways. |

Re: Engine temp rises when I get to cruise speed
I find it unsettling that a reputation is worth less these days than a radiator. Then again, with Walker out of the picture, perhaps a reputation is not a prerequisite to selling radiators after all.

Re: Engine temp rises when I get to cruise speed
Alan as the internet works. All I have to do is say something and people will gang up even if they have never bought or know what is happening.
Time will tell though. No reason to speculate or condemn a system that might be great for a lot of other applications that are not for some specific moded version. Kinda of limiting a player. But... quick to condemn and slow to forgive. Cancel them? Time will tell. Remember this whole thread is based on one persons motor. . |

Re: Engine temp rises when I get to cruise speed
Maybe every time things don't work out. We shut them down. Leaving us with our d!cks in our hand.
I think that's how Don Prudhomme did things. When it didn't workout he posted on social media. If you are questioning what rads I run, They are re cores. Not sure I could find some one today that could do it now. Never have purchased or worked for Brassworks. Probably the best bet is they can give him his money back and walk away. Just my opinion. .
