I have a M6. I am condidering NOS. Never had it before. In a 1/4 mile run, when is the best time to spray it?? What gear? What RPM? Any info will be alot of help here. Thanks in advance!

 

whenever traction is available

 

do you want a NOS kit or do you want n2o? spray out of the hole but you need to get a lot of suspension

 

I want a NOS kit. WHat are the first suspesion items I should work on?

 

Gotta start with the basics with suspension.
Lower control arms,relocation brackets,shocks/springs,frame connectors.
Best use is to spray right off the starting line if you have traction.

 

i was told a while back that as long as the butterflies in the TB are at WOT, or completely open, its ok to spray. now in my car i dont have a stall, so just leave off idle. so, as soon as ive ive the peddle to the floor i go to the button. actually, its more like at the same time. thats the way ive been doing it since i got my kit (3-4 months) and thats the way ill keep doing it.

if youve got a M6, most guys ive talked to will get the rpms up where they want, and actually go to the button just before dumping the clutch.

For the best ET spray from the tree. Traction permitting.

 

You should not spray at very low rpm. Doing so causes excessive cylinder pressures, which can break parts!

BMEP = HP*6500 / L*RPM is one formula that illustrates the relationship between cylinder pressure and hp (L=displacement in litres). So, if you add a 200hp nitrous shot at 2,000rpm it will produce twice the average cylinder pressure increase as the same amount of nitrous would at 4,000rpm.

Of course, it's peak pressure and not mean that breaks things, but the relationship still holds, and in fact, peak cylinder pressure is higher for a given amount of nitrous hp compared with NA unless the tuning is done carefully (mostly, retarded timing especially at low rpm).

I have mine setup to activate at 3,200rpm and would be cautious about going lower.
