Chargecooler-Moto concept

[roadburner]

Hi,
Moto concept sells an bigger chargecooler for the Esprit.
Is there any reason why i should install it in my car?

What year and model do you have? Are you changing or putting in a larger turbo and other performance mods?

I only got another MemCal,Blow off valve and an sports exhaust.Ìt`s an 92`SE.

Unless you are going to larger boost turbo, increased fuel pressure, larger inlet valves. I really can't see the larger intercooler would make much difference unless you doing some serious racing. But it might do a better job at keeping the system cooler at slower speeds though but an electric chargecooler pump might make more of a difference. Seems the stock pump cools better when the engine is turning faster. Sometimes you need full boost before the pump gets up to speed and starts cooling the intercooler. I would suspect a constant velocity chargecooler pump will keep the temps down as well as a larger intercooler for our application with a less expensive cost.

Yes, buy the bigger intercooler.
I was told by one of technicians that use to race the lotus in the U.S. that the street versions were insufficient.

I concur with cnh1990. I just baught a '91 SE, and my chg cooler pump is shot, so I have been reading up on this engine component. I think that a good source of info on this topic is the Mark Whittiker (sp?) web site (one of the links on the fact file site). He thinks it's a good idea to replace the mechanical chg cooler pump with an electrical counterpart. He claims that it is effective, cheap, and easy to do. He also offers some specific instruction on how to go about doing it. He used a 12 volt Ausi pump. I have desided to use a 750gph "Live Well" pump, the kind used on small fishing boats. The entire works will cost me about $25 USD. On the other hand, the kit to rebuild the factory chg cooler pump is about $70 USD. What's more, it's tough to do, and one can look forward to rebuilding it over and over again every 25K miles or so.

Aside from the cost and reliability issues, I think that it comes down to this. There are two basic ways to reduce the temp of air going into your engine. Increase the surface area of the heat exchanger, or increase the flow through the heat exchanger. Each method will carry away more heat. You can greatly increase the flow for about $25 and one afternoon of work. What is a larger chg cooler going to set you back?

Hell, maybe you'd want to do both. The colder..the better.

Let me how things turn out for you. Regards...Walt
