nitrous help

[shagn03]

I am in the process of installing a custom dry nitrous setup and was just needing to know what size jets to use for a 30-50shot.

There is a "Real Street Car Shootout" here this comming weekend at the local track. I think with the nitrous I may have a chance to get in the top 5.

Any advice or recommendations would be appreciated.

Thanks

According to this calculator:

the jet sizes for the following shots would be:

30hp: .026 jet
35hp: .028 jet
40hp: .030 jet
45hp: .032 jet
50hp: .034 jet

Thanks Bryan, much appreciated.

Anyone have any suggestions about adding fuel with the predator for nitrous passes or just rely on the mass air sensor.

hmm, I am kind of scared spraying through the MAF, but many have had good experiences with it. Others havn't though. I am not sure if the Predator would be able to add enough fuel for the shot by the user adjustable settings. You could always have a custom tune emailed to your Predator, and use on the days when you know you will spray! I am personally going with the Edelbrock kit. I assume you are using a Compucar like kit?

Most say with a small shot of 35-40 you wont need to add fuel in your tune or take out timing.

I know grnenvy is making big power on a 40 shot with just 3 degrees of timing yanked out of his regular blower tune.


The rule of thumb is for every 50hp of n20 take out about 2 degrees. You can also use a fuel additive to help out a tad.

I am going to run a 31 jet which is a 40 or so then a 38 which is about 60. If I feel lucky I will step it up to a 41 jet which is 75

Thanks Broke, are you going to be using that plate setup as a dry shot or wet??

I cant wait to see your new numbers with Apten and the nitrous....
