Single cam N20 coupe help/opinions
So I have a 95ex coupe with a fully built high compression single cam vtec motor. Head is fully worked and all.
Im going to be running n2o on it thinking about an 80 shot Dry shot controlled by the fuel thru the ECU using hondata s300 on it for tuning. 750cc injectors. 2maps one for daily driving on 91 oct and the n2o tune with be on e85.
So im not sure what the compression on the motor is currently. It blows in the 180's to 170's accross all 4 cylinders. Out elevation is 5500ft in albuquerque New Mexico. If anyone knows how to calculate the compression please let me know. As far as i know the motor has stock bore.
Has anyone ran a setup like this and what kind of numbers should i be expecting from the car. I will have the car on the dyno about march 21st ill make sure to update the site with those numbers.

Re: Single cam N20 coupe help/opinions
Thats what im trying to find out now is the compression ratio...
I hear its 12.5 or so. I figured you could figure it out somehow by what it blew.
How safe is it to run 91 octane at this elevation with just the motor no n2o?
