He can claim anything he wants. This is the internet.Sorry to be so negative, but all I see there is a waste of money and time.
Not at all, but we can only guess.
He said, he'll prove you wrong, try his car with intercooler gauge (in/out) to prove.
His design is simple - no maintenance - like a brick compare to
complex water system that lots of things to go wrong. He's a lotus garage.
He offered & I will try to drive his car and I will let you know.
Air to air is generally more efficient than air to water if it's employed reasonably.Water intercooler is more efficient than the air to air. -----What he did is to try something different.
Small world, I remember seeing a photo of your setup quite a while ago and based the design of mine on it.Here is mine as well --- yep, over 20 years ago, almost the same as Charlie Seabrook design. It works pretty good too - I was constantly boosting 13psi...no detonations.
I have an intercooler gauge (hot & cold side). Mine was a Spearco matrix. Those were the days.....
Here is my intercooler temp gauge (IN/OUT) http://img31.imageshack.us/img31/7534/p8240036.jpg
If I remember I cooled it 38 to 40 %.
In some ways it probably went out of date as soon as it was published.Gizzer,
Good recommendation on reading "maximum boost." It's a little outdated, but there is a plethora of turbo knowledge to be gained by reading it. Really good at breaking down compressor efficiency "islands."
Sorry my post had no graphs or indepth technical theorys, but I guess you feel better now you have pointed all of that out.In some ways it probably went out of date as soon as it was published.
But most of the info is for system installation and testing. That doesn't go out of date as fast.
Bell made me aware of all the ways that an intercooler setup could go sour and what to aim for in a good installation. This is where I determined that the factory setup is pretty good, considering what they had to work with.
IMO it's also best to try to push people into reading up on the subject to try to get a grasp of the basics, then make their own decision on what's best for them.
Downloading a picture on the internet with a couple of words claiming "it worked OK for me" isn't very helpful. (however it is always food for thought) It is also dangerous to imply that a carbed setup worked, so a fuel injected setup will work well also.
The dangers of the internet sound bite.
Another wrinkle is that what worked good for them in the past may not be acceptable today to 90% of the rest of the world.
(sorry, but it has to be said)
I still think the air to air intercooler sited in the Lotus Esprit engine compartment is a dead-end effort from a performance standpoint.
It's a genuine "what were they thinking?" moment for me.
So anyway, I've said my piece.
