<<   You can buy TEL in bottles, called "octane booster" if you are
 convinced that you MUST have it - but the lead ruins the catalytic
 converters (coats the active surface) which is why (one of the reasons,
 anyway) we now have only unleaded gas.>>>>
  And it is not the same additives used in racing fuel....  If you are going
to the track find out if the pumps are open, buy the gas right there....  If
not, find a local source for hi octane racing fuel, tho, remember it is
illegal to dispense it "directly" to your tank....  So, you must bring tanks
(Military "jerry" cans are good for this, btdt) to the pump.....  Warning:
AVGAS is not the same (archives conclusion: at least not here in the states),
it doesn't have the fuel pump conditioners the racing gas does, you risk
burning up your fuel pump......   >>>>>>
 
 >>>>>>        Incidentally, super high compression ratios are really more
trouble
 than they're worth. They make for hard starting, short component life, and
 an insatiable appetite for hard to find, expensive premium and racing fuel.
 Work on easy breathing (chips, free flow air filter, headers) and more
 displacement for lower costs, longer life, and more HP.>>>>>> 
.... Hmmmm, might disagree with you a little here, a turbo (esp with mods)
car does much better than a N/A in this department, especially when advancing
cam, adding more boost.....
 
       >>>>>>>>>>>>>  (Same comments go for advancing the distributor timing
for more HP -  you ARE GOING TO hole a piston doing this!! Believe me, if any
auto factory could get "Free" horsepower just by twisting the distributor,
don't you
 think the marketing department would be RIGHT THERE at the dyno, ready to
 write the new sales brochure (Now!!! 300 more HP at the same price!!! Buy
 one today!!!)>>>>>>>>>>
 
 Hmmmm......  A little off there...  Any A1 or A2 vw owner knows that this is
not exactly right, in fact you twist that dist between 4&8 degrees advance
depending on mods, 4 with none right off the bat....  Having raced and street
a GLH turbo of mid 80's vintage with a turbo, 14 degrees ignition advance (vs
7 stock) was common WITH boost mods in the 17psi range with no IC....  The
marketing department is not going to give you mods on the sales brochure, cuz
standing right behind him is the EPA-dude ready to flunk the same car.....
 Most of the chips for normally aspirated cars do little else than tweek fuel
and timing maps, most under the guise of WOT free rule of EPA.....  Tweeking
the distributor (ignition maps) is where a lot of turbo chipsters are heading
now, with the range of timing available in an electronic dist, it really is a
good idea....  Can you go too far, sure, but I would propose on a turbo car
with a knock sensor that spot will be pretty easily found...
