Need help with nitrous

[30thSSclone]

So as my build is coming along....I'm on the breaking point of throwing the nitrous on it now....my question is, I've heard good things about the digital 6 box for adjusting timing. My question is, is that still used with the opti? And if so, how hard is it to wire up. And as far as injectors go, I have LE2 heads and intake with a big cam and 355. Should I go 36 or a 42lb injector?

Digital six works with opti. .. just need the harness from the coil. .. get some 30s.
. They will plenty for your build. ..
But new ones and have them flow matched

[30thSSclone]

Okay. Next question....nitrous controller or just the digital 6 box?

What kind of NA HP are you estimating (at the flywheel)? My rule-of-thumb is multiply the NA flywheel HP by 0.070 to get a reasonable, minimum injector size. This assumes you have a moderately efficient tune running 0.476 #/HR/HP BSFC, and don't want to exceed 85% duty cycle on the injectors.

For example, 450 flywheel HP x 0.070 = 31.5 #/HR

Digital six has timing retard. .. 2 step and window switch. ... that's pretty much everything. .. if you are looking to progress the shot you will to have to add a progressive. ... depends on how much you want to spray. .. If your just looking for 100 to 150 I wouldn't even bother with a progressive unless you have NO suspension in the car

[30thSSclone]

I don't have any suspension. Probably next year it will get coil overs. But I do have SFC's

Digital 6 does not have a window switch...that is the Mallory 685

before buying an ignition/box retard first thing is too look at how much timing you are going to need to pull. How much nitrous are you looking to run...now and in the future?

[30thSSclone]

I'd like to hit it with a 150 and see how it reacts. I might put a 200. But no bigger

[Chopstix]

Digital 6 will be fine there...it can only pull up to 9.9 degrees.

If you want to get a progressive, as far as I'm concerned there are only 3 options.

Leash Electronics - Randy Westmoreland built these in his garage and has been scaling up since then. They are STUPID SIMPLE, easy to use, easy to program. No hooking it up to a computer or anything.

Edelbrock - NOS Launcher, also stupid simple and I've seen some retarded fast cars run this. I saw an old Jerry Haas Pro Stock Truck with a 630+cu in BBC and a ton of nitrous kick the shit out of everyone at a big race with one.

NLR - Expensive but the best.
