Is higher compression a factor with nitrous like it is with s/c and t/cs?

 

i am pretty sure higher compression is good for running nitrous.

 

no it is not...it is still forced induction

xx are you wondering why ls1's use nitrous with their higher compression engines?

 

Nitrous likes compression.

 

care to elaborate??

 

Well, let's see...Pro Mod car run 15.0:1 compression with alot of nitrous. The key is to have proper timing and octane.

 

i know some things about nitrous but im certainly not an expert. i'd just like to know why (as detailed as possible) so that i know the reason...not that it just does or doesn't.

 

With nitrous there is excessive chamber pressure as with all FI applications. With high compression (usually over 10.0:1) there is more probablility of detonation, especially at upper rpms. With the addition of nitrous to high compression, it is essential to keep the timing in check and to have a higher octane rating. With the timing and octane correct, a high compression motor will THRIVE on nitrous.

 

thanks code....but im a bit confused. assuming the timing and octane count are correct, why doesn't boosted apps thrive on high cr engines?since nitrous is still fi....what makes the difference? how can an engine with a cr over 10.0:1 take a 200+ shot on pump gas but only a few psi of boost on pump gas?

 

It's not that you NEED high compression to run it. But for best results and best power out of nitrous high compression is the way to go. That's why nitrous is loved by turbo cars. I have talked to quite a few turbo guys and they all tell me that a 50 shot on a turbo'd car is like a 100 shot on a N/A (probably one with stock compression). It is a trade off like anything else. You use nitrous on a stock compression or average compression application and you'll get power but not the FULL potential of the shot but you run it slightly safer. While on the other hand, you can get the FULL potential on a HIgh compression application but you run into danger of detonation and having tooo much compression in the system. Just like boost.
