Principles of Engine Cooling Book "LoPresti"

rv969wf · #1 10-05-2006, 03:23 PM

I've bought a lot of books in my lifetime but who is going to pay $1,500 for a book?

YES around $1,500 for the "Principles of Engine Cooling" book by Jim Lopresti. LoPresti quoted that if enough people are interested he might bring the price down. Down to what a $1,000 ???? This is nuts in my opinion. The Aug 2006 issue of Sport Aviation on page 144 has an add for this book. Jim mentioned you can't even buy the book right now so why put the dang add in the magazine. Jim has an email address btw: drjim@lopresti.biz He mentioned for anyone interested to write him and he'll see how many people are interested in it. Yes I'd like to have one and would pay maybe $100++ but not $1,500. To print each book alone he said would be around $50 btw. If any of you speed freaks or cooling mod builders are interested in this book it would be nice to show some interest and email Jim and try to get the price down. Anyway I'll quit complaining.

Alan my friend that is insane. First Roy his dad as you know has passed and was a great designer and incorporated technology. Of course Jim his son is now running "Speed Merchants", makers of after market cowls and other speed mods like gap seals for factory planes. I would save your money. Although a little dated and not glossy, I recommend "Speed with Economy", by Kent Paser. I think it's $20 and worth it. I have a lot of technical books and about $80 was tops.

I talked to Jim LoPresti about buying a part from one of his kits, an oil cooler diffuser. He asked me what I was willing to pay. When I threw out $100 he laughed at me. I think we where way way off by a factor of 5 or 10. I can make my own fiberglass part, thanks. That is why I have an experimental, so I am not at the mercy of vendors, FAA and factory parts.

There is a lot of data out there and a lot of it is free.

Alan, as you know I have been working to reduce the cooling drag in my RV-6A by working with aluminum baffling in the lower cowl. So far I haven't run into a heating problem so I will continue the experiment and on the job learning process. I just don't think the book would do me any good at this point. Sometime I would like to learn about the race engine building that you do however.

Wasn't there an article in the RVator a number of years ago about two friends in Ohio who both built 6's and had a friendly competition as to who was fastest? If I remember correctly one of the guys modified the inlets in his cowl and gained a few knots.

OK, If enough people show an interest in this book, then I will buy a copy, and I will photo copy a book for each of you. $ 79. Any takers?

The only thing Jim LoPresti is qualified to write about is how to [snip by dr] people into paying huge money for everyday stuff. Check out his landing lights for crying out loud!

The Article is in the second RVator issue of 2000. The title is "Over 200 mph on 160 HP" and there are definitly some good ideas in there. The 3 mph gain achieved by fairing in the tail tiedown ring is a "must try". The 5 mph increase achieved by running the intake scoop up near the prop is not something you want to do if you have a completely painted nice looking airplane (thousands invested) but that is a lot of speed. It is interesting to note that they refer to Kent Paser's book "Speed with Economy" that George suggested earlier. It seems a lot of us have a copy. In Chapter 4 he goes into his "Engine Cooling Modifications."

Hey Bob,,, check your Private Messages, I left you one today. Give me a call sometime and I'll share some things about what I have done on Air Cooled Lycoming engines to make them run cooler so you can go faster with less cooling drag. I have 5 years of documents and testing since 2001 on my RV-6 project. I've done some things that a lot of engine builders / RV builders would not of thought of. Heat dissipation inside and out is the key with an air cooled engine. I will share with you what did and didn't work on my 6 if you want to talk sometime.... One other thing,,,, the LoPresti Book I found out is more for engineers that talk a different language than most of us. Book involves air and water cooled engines both. Thanks......

Copyright laws only work when prices are reasonable enough to keep honest people honest. When a publisher/author decides to gouge, folks will ignore the copyright. I hope Lopresti plans on saving that $1500, cuz he'll sell exactly one copy -- the rest of us will get xerox's, e-copies, etc.

$1500!! Gimme a break.

A big 10-4 on that comment. I fabricate quite a few things to sell to the average builder and I make my 15-20% markup but good gosh, a book at this price will NEVER SELL, why did he even write the darn thing. Who can afford it?????? The only people that can afford it are the people that hire their work done by someone else to have fast airplanes and are they going to read it? I don't think so.... When I talked to Jim L...today I just about dropped the telephone at the price, heck I even had my credit card out ready to give him my info and order it. I just sat there for awhile and as we visited I decided to just go have a cold one and share this story with everyone....What the heck it's a free world and I didn't want anyone to waste their dime calling to buy this million $$$$BOOK$$$$$
