whould running meth injection on a built high compression gsr motor a good alternitive to not running race gas?

also whould it still be concidered N/A with meth?

please clear this up thank you guy!

 

?? anyone?

 

Yes you can run it so you don't have to run race gas. If your gonna be running at events in an all motor class, NO it can not be used. If the comp in your sig is what your talking about your border line for pump gas. Some people say 12.5.1 is the limit for pump some say 13.0.1.

 

WORKS GOOD IN HIGH COMPRESSION MOTORS IMO

 

Yes meth is fine but you'll have to run brackets. All heads up street all motor classes prohibite methanol. Unless you're looking to run Pro AM. I would look into E85. Poorman's race gas...

 

we have no e85 around our area.... what about 93 pump with tolulene? (however you spell it) will that work and yield me the octane level i need?

and if i just run straight 93 pump what whould YOU tune with to get the most power out of her?

 

I hope you have some big cams too to help make everything work well together.

 

What does cam size have to do with anything? Meth injection work well with any setup.

 

cam size has nothing to do with building a high comp na motor?

 

tolulene will eat away at your fuel lines. yes you can do it but its not smart. a good tuner will take care of you and be able to make you run on pump

nope

 

Cam size has nothing to do with compression. Now the performance of a high comp motor....yes. Plus the OP ask about Meth injection as an alternitive to race gas, so cams, compression, boost, or N/A has nothing to do with his question.

 

i know this is the NA forum, but i run toluene and e98 2:3 mix in my boosted civic. seems to work well and LOVES timing.

 

so cam size as in duration has nothing to do with compression, please explain.


really. have you ever heard of dynamic or effective compression ratio. if not read into it. it says that your true cr ratio doesn't even start till the last intake valve is closed and the cylinder can actually seal. the more duration you have the more of your static cr you can "bleed off" (hate to use that term) hence why I asked if he had big cams to make everything work well together.

if you think other wise id love to hear your argument or maybe Im just not hearing what your getting at here.

 

Ok maybe I think out of the box to much. So with what you just said, Valves closed and cylinder sealed. Wouldn't that be just like not having a cam in the head? Or am I seeing something wrong here?

 

the valves don't close until after the piston travels up a little bit. this depends on the duration that the cam has. this is why cam choice has alot to do with what cr you can run on pump gas.

 

It's all about when the valves open and close, chief.
