There comes a point in your power buildup where you may consider adding nitrous oxide injection to your supercharged car. This point typically coincides with reaching a level of performance that means increased investment and diminishing returns from your supercharger. For example, my car comes from the factory with a 5th generation Eaton MP45 supercharger. This supercharger is limited to about 230hp worth of flow rating and so no matter what I do with bolt-on upgrades on my engine, my peak horsepower will not exceed 230hp limit because that is the point at which the supercharger becomes the bottle neck in my system.
As we’ve talked about in previous articles there is still the option of porting the factory supercharger for a 10 to 15% gain in capacity (which in this case would be another 23 to 35 horsepower). There is also the option of retrofitting a larger supercharger such as the Eaton M62 to gain potential up to over 300hp depending on the final choice of a supercharger.
This modification path (porting or replacing the factory supercharger) can prove to be complex and costly, especially if the supercharger is integrated into the intake manifold (and possibly an air to water intercooler) as the case is with many factory supercharged cars.
A possible viable solution for this situation is to use nitrous oxide injection to supplement the power delivery when racing, and being satisfied with a reliable lower powered car when the nitrous is off and we’re not racing.
The reason why nitrous oxide (N2O) becomes a great power adder is twofold:
1- Nitrous is cheap as far as horsepower per dollar goes, and especially in the situations where we’re already supercharged and so will only be using it on the rare occasions when we do hit the track.
2- Nitrous oxide is a great ‘chiller’ as it comes out of the bottle at a temperature of negative 127*F

I just bought a 68 mustang and I am looking for a good performance shop around Raleigh NC that deals with older cars, suspension work, and motor swaps. Any help is appreciated. Thanks!

I have a 1993 Pontiac Grand Am GT V6 and it has a hole in the muffler, but it sounds good. However, it does need to be replaced because of the hole. I would really like to find out what kind of muffler would be best for my car to make it sound good, but I don’t want it to be really loud, just enough to be noticed on the road and by other people. Would a Cherry Bomb turbo muffler be too loud, or do i need to go with a Flowmaster, or something else? I also want it to be as inexpensive as possible.

I need expensive things, like electric water pump, carb, air cleaner, heads, oil pan, etc. Things are just to expensive through summit or jegs. Is there anyway to get discounted parts anywhere other than ebay or craigslist?

Your Pontiac car is a complex assembly of car parts and accessories that enables it to perform exceptionally on the road. The exhaust system is among the integral systems in your car that is tasked to lessen harmful engine emissions, reduce the sound level of your engine, and deploy engine exhaust gases to the rear of your car. As a system, it is made up of a number of components. Every exhaust system part has a specific function to perform—that is why your entire exhaust system will not function properly if one or more of its sub components failed to do their part. There are different types of exhaust system: the single exit cat back exhaust, dual exit cat back exhaust, and performance diesel exhaust. But no matter what type of exhaust system you may have, they all have the same number of components—and among these is the Pontiac exhaust tip.
Your Pontiac exhaust tip can be seen at the end of your car where the exhaust gases are vented. This exhaust system component is the only visible part of the entire system that is the end of the final length of the exhaust pipe. Compared to the rest of the exhaust system, the Pontiac exhaust tip is often the larger pipe. It may be among the least maintained parts, but your Pontiac exhaust tip is among those parts that affect the performance of your car. The exhaust flow as well as the over all tome of the exhaust tone of your Pontiac depends on the construction and shape of the exhaust tip installed on your car. The accompanying sound and the remaining pulses of exhaust gases are shaped in the exhaust tip as they exit from the pipe. As a matter of fact, a long pencil-shaped exhaust tip will definitely sound different than a short megaphone exhaust tip. The manner of installation of your Pontiac exhaust tip can also affect the sound coming out of your car. Screw-on Pontiac exhaust tips provide a less solid sound as compared to welded or compression clamped Pontiac exhausts tips that produces a more solid sound.
Aside from performance enhancement, your Pontiac exhaust tip can also add some visual style and aural punctuation on your car. Custom exhaust tips are among the most affordable car styling enhancements around. The automotive market offers various styles, finishes and construction of exhaust tips. Some of these include trumpet exhaust tips, tapered exhaust tips, dual exhaust tips, single exhaust tips, megaphone exhaust tips, mellow exhaust tips, square exhaust tips, quadruple exhaust tips, triple exhaust tips, oval exhaust tips, as well as oval exhaust tips. However, you need to consider a few guidelines when choosing the right exhaust tip for your car. You can choose the biggest and the loudest if you want an over the top style. You can add subtle yet unique style on your car by following the predominant shape, general mounting direction of the bodyline, and mounting flush with the rear valance of your vehicle. So get a stylish yet functional Pontiac exhaust tip at your preferred car parts dealer online or offline—and add some shine to that space below your bumper!
