The results are not worthless and I'm not wasting my money. As long as all the runs are done under similar conditions valid conclusions can be drawn.
I have a degree in mechanical engineering and I know a thing or two about heat transfer. You've missed the point - the stock IC soaks very rapidly and would soak very rapidly in any dyno environment because it has a low heat capacity.
Lotus had design criteria which were reached by their engineers - that doesn't mean they can't be exceeded by other engineers with different design criteria.
If you don't want to be part of the experiment that's fine but don't tell us that the study is invalid when in fact it's very valid and very pertinent; the fact that a more massive IC can absorb much more heat does not need to be proven - it's a fact of heat transfer.

Well, maybe you ought to figure out who is out there.
For one I am and I can tell you for certain that your information is inaccurate. Our dyno cost $250K
Not to mention the facility. And in another facility down the road a colleague is building an engine dyno for race teams that he supplies engines to -- Grand AM & ALMS.
Similar conditions? Controlling all the variables -- are you sure? For if just one is off the data is invalid. Just one! Did you read the short essays on the web page? And if so, did you understand them?
No I have not missed the point...yes, the Bell intercooler is more massive by what, 20%? I've been waiting for mine for weeks now. But they will only work on the race track where air flow is sufficient to cool them.
For the street why care about heat soak? Stop light to stop light

This is what DMH Motorsports does. Want more information then call, email, or go to monkeytuner and ask me there.
