[Es2] things that tend to break on es2's at the track

Wed Jun 7 11:32:18 EDT 2006

I guess it will be a somewhat easy test given the weather forecast but
it currently has no ducting to it with much tubing in front but does
retain a fan and shroud on the backside.

The only day I have really driven it more than 5 minutes it ran between
80 and 90 on a warm day of easy highway cruising.

Peter:  Keep in mind that you ran Lime Rock with your stock 7A
(170hp+/-).  An S2 is what, 50% more HP or more?  That's 50% more heat,
too. 

An S2 may also pre-heat the air by putting the intercooler in the grill;
that also reduces the volume of air flowing through the radiator.  Bad.
I'm hoping to make the stock 200q20v radiator fan work with my coupe;
will need a custom shroud.  Much larger motor than the coupe uses in 7A
form.

Chris/Adam:

Anecdotally or not, I have heard first hand that two users of the 034
radiator have had some issues with cooling efficiency - but their
installations used neither the stock ducting to the radiator or the
stock radiator fan and ducting....evidently keeping the stock ducting to
the 034 radiator and the stock radiator fan and shroud makes the
radiator work more efficiently than no ducting/and a pancake fan -
....remember that the B3/B4 radiator location has little frontal area,
so ducting in and out is important for airflow.

I can attest to that having run twice at Lime Rock with track
temperatures over 100 F that the 034 radiator, including the stock AC
condensor and running the stock ducting and radiator fan, is more than
up to the cooling task, even without the auxiliary radiator.
