Well, for a completely stock 1.6L you can safely turn 6400 but only for a 
short time. Thats pretty high for that torquie little motor. You may want to 
consider changing the 5th gear if you go with the smaller tire size. 
(Depending on what you have and can change to, ect.)

Factory suggested redline doesnt really mean anything as far as each 
individual motors concearned. Its just a reference point. The real redline 
should be where the hp and torque curve drop off. Theres no point in reving 
it higher than this. Now, as far as running a stock and old 1.6L hard, you 
will have power drop off's due to the valve springs floating. Thats probably 
the first thing you will notice. That pretty much hammers the valves pretty 
hard. Ive never heard of a motor blowing at high rpms with failures anywhere 
other than the valve train and/or cam failing.
Use the little sensor in your butt to tell you when the motor quits pulling 
as your redline reference. Thats a good reference point when you dont have a 
dyno! (If you race it, then you know what im talking about!)

WOW!! Great page! Its not all cluttered with crap like mine is! You also 
write very well. I read every word and was even looking for more! I cant 
believe you dont have a pic of your victory circle? Congrats on your first 
win, may it be one of many!
With the head gasket leaking like it is, its only a matter oftime before it 
lets loose completely. How long until it does, I dunno. Could be next race, 
could be next race 5 years from now. Id say just run it and while tha
ts going on, find yourself a used head and get working on it. I dont know 
what the rules are in the class you run in but im sure you can P&P the head? 
If not, im sure you can at least port match the head. You could be slo
wly building it until this one blows. Its really nice to have spares laying 
around you know!
I completely envy you! Is this a Nascar sanctioned event? 
I live not 3 miles from the El Cajon Speedway. its a 3/8's  mile paved oval 
nascar track. They have a Pony Stock class but you have to drive a domestic 
car to race there. (Sorry, not interested in driving a ford..) It also costs 
a fortune to race there too. $14 per person and $50 per car. Its just out of 
my budget right now but it sounds like you got yourself a heck of a deal on 
that Scirocco you race! How much do you have in it, if you dont mind me 
asking?

Maybe I need to move to Raleigh, NC so I can race in the roundy-rounds! All I 
have access to here in San Diego is Autocrossing and the ocasional road 
racing at Buttonwillow or Willow Springs. It costs me $250 to roadrace! ACK!

Anyways, back to your car, what are the rules of do's-donts that you can 
modify on the car and what have you got in the car now? (Suspension pieces, 
ect..)
TTYL!
