tom at supersix says nitrous loves compression some of you say different please help

[bluecmaro96]

tom said nitrous loves compression, im getting compression taken up 2 around 10.0:1 why did some of you say raising compression with a poweradder is bad? did you mean just supercharger?

[Jason]

SUPERCHARGERS and TURBOS dont like high compression...Nitrous LOVEShigh compression. Not sure on the reasoning why just yet but im Sure SOMONE can answer that for us both.

[strobhen]

raising compression w/ a poweradder increases the chances of detonation.

and in the case of a supercharger/turbocharger, you will get more power by lowering boost to 8:1 and running max boost than 10:1 w/ max boost.

I don't know enough about nitro to really comment on it, but I'm sure Tom does. Nitrous helps to cool incoming air, so increasing compression doesn't bring on detonation as much as boost does.

[RiceCooker]

Excess heat causes detonation.
It would be optimal and ideal to run high boost AND high compression, but b/c the air is highly compressed, it will heat up and cause detonation. That's why you're better off running low compression and high boost. This is all assuming that you are on 93 octane, not anything higher like race gas or a mixture.
Nitrous does raise the compression dramatically, but b/c it is SOOOOO cold, detonation is not a factor in a high compression motor. Also, there's the fact that it is not run constantly like forced induction.
Bluecamaro96, your motor plans sound identical to mine, including the compression. I'm still debating on increasing the bore or not.

I'm going to have to get back to you on this question on compression and nitrous. I remember reading something on it but I'm not 100% sure so I don't want to say the wrong thing.
I will post my results when I research it

nos runs better of low compersion enginges but no hp on motor but will run beter than high conpersion motor because the lower the comp. the bigger the shot

I disagree, you will make more power with 10:1 and max boost, what really matters is the detonation, if you can cool the charge, you could run 16:1 and 43 psi, but you need the internals to do that.

nitrous will run faster with more compression, just on the street, if you run too much compression, you detonate, unless you buy the high priced, high octane unleaded gasoline from, VP, Howell, or Sonoco

High compression ratios can be used with nitrous but shifting the maximum pressure after top dead center becomes more and more difficult. I prefer to use street compression ratios and then just work with adding more nitrous to get desired horsepower levels.
