Well that is the world of street racing! The intake roar is more noticeable, but you don't have to tell the competition everything! The timing is a more helpful deal anyway. More than the lack of an air cleaner or thinner oil. Of course that is another trick for a few more horsepower, synthetic oil. It is better and clicker and is better for your car, unless it leaks or burns oil pretty bad then it gets expensive.

Try to get the timing to be at least 34 or so degrees total timing advanced. You will have to use premium fuel, but the added hp is very noticeable. If you notice it pinging under acceleration then back it off a few degrees and try it again. When, or if you do up the timing, you will have to back the idle down some too.

These are all things street racers have done for years, and more. You want your car to run its best at all times of course, but for short bursts you can bring things closer to the timing edge so to speak. Another thing is you could play with the cam timing a little. If you wanted you could advance the cam timing a degree or two and get a little more low end at the sacrifice of a little top end and the same with retarding the cams.

These are things you can do that will not hurt your car any, but let you play around with the parameters of the car. You could even put an electric fan on for a few more easy horsepower. All these things are small initially, some more noticeable than others, but added together can make a 1/2 second difference in a quarter mile and that is a lot for free.

Just giving you things to consider. Make sure you have torqued your head bolts to 70 ft lbs at least to take care of any gasket problems. We all know that racing any car does put more strain on a car and wears parts out faster, but it is fun to do occasionally.

Good luck
