Forced induction is the way to go. Let me qualify that a little.
Spray is great and you can make big HP & torque with it. For 1/4 or 1/8 mile racing it is a very good way to go.
Forced induction gives a seat of the pants boost that is always there. If it is engineered properly and tuned properly, boosted motors are really fun to drive.
Many here are trying to test the limits of stock engine and driveline parts. This can be done with NOS or boost. The results are usually the same. catastrophic failure.
There are a few that have done their homework and built a "combination".
That is not just bolting on parts that will work. That is coming up with a package of parts that compliment one another.
Tuning is also very inportant.
I see a disturbing trend to use a "Stage 2" flash and run NOS on top of the flash. This in my opinion can lead to massive engine failure.
I also see a trend among people that have "Modded" the engine to not accept responsibility when there is an engine failure. If I want to modd/build my engine I have to accept the fact that my engine warranty is void.
Any aftermarket parts I install are also done at my discression knowing that it will void my warranty.
I knew a fellow that had an oil leak, he had a large capacity oil pan and a preoiler. He chose to drive with the leak. His motor was ruined.
All his buddies wanted to blame the maker of the part that started leaking.
His comment to this was "I should have paid attention".
Whenever there is a good sized oil leak it is my responsibility to pay attention to the smell, the smoke or the other signs that something is wrong. And these signs are always present.
We have HotRods, and as such we have to pay a fair bit of attention to them. They will usually give out warning signs that something is wrong.
Your eyes and ears are the best diagnostic tools you have.
This needs to be followed up with common sense
The bottom line is, if I want to play I got to pay.
