Looking for thoughts from you guys on a spark plug to start out with on my new engine combo... Don't want to release too many details as it's going to be a street/grudge car and I plan to take some money from people around me, plus a lot of them lurk on here lol.

However basic idea is this:
patriot performance cathedral headed ls3 based shortblock around 10.5-11.0-1 compression mild 234/238 .620" 113lsa cam fast 90/92mm with outlet plate system
200 +/- 50 shot of nitrous

I have 24 ngk b8's and 24 b9's in stock lol

93 octane in the tank and 116+ octane in the dedicated system.

What you guys think I should start tuning with?

thanks.

 

I think you should find someone that knows how to tune nitrous cars.

 

You sound brilliant, why don't you come show me ?

 

Well, i would start the initial hit at 100-150 and i would start by using BR8's and go up from there. Just make sure the N/A tune is good on the BR8's first. Then step down the plug when needed as you spray more and more. This, would of course be the safest way. Also, make sure if you step up to the 9's the N/A tune is adjusted for it, it will make a difference.

 

Thank you, appreciate the constructive post. I do not tune using HP Tuners, I have that done by Twisted Synergy. I have the capability to make small adjustments later using my friend's HP tuners interface, but to baseline and dial in a car with a completely new motor, trans, and fuel system...that's just plumb above my pay-grade. I planned to have the tuner dial the car in on the 8's and hit it small with the 100 and then a 150 shot on the dyno there using my LNC2000 to pull the appropriate timing on the spray. Then I'll tune it out and bring it up to 200-250 on my own from there. I just didn't want to start off with the 9's if someone here had run a similar combo and found that to be too cold to start with. That is why I was looking for an idea of what to start off with rather than toss $30 in plugs in the trash for nothing.

 

I have a 11.5:1 compression HCI 6.0 with a 150 shot and run BR7's. I really think you should be fine with the 8's

 

Thank you sir! Looks like that's what I'll start with and read from there.

 

Maybe you took my post wrong or maybe it came off wrong. What I should have said was, "find someone who knows nitrous cars to help you out"

You need to learn how to tune. You need to learn how to read plugs. You need to know what ACTUALLY works on a nitrous engine and not listen to 90% of the forums. (Yes there are a lot of really smart people on forums, WAAAAAY smarter than me, but you have you have to dig through the bullshit, through the "what's popular this month" bullshit.

No bullshit though.

If you have a "grudge" car that you can't release the top secret spec's about and are asking the ******* internet about where to start.........yeah you need to find someone who knows nitrous and how to tune it.

OR

start out with a small hit, learn how to do all the things I listed above and work your way up.

But if you think that the internet is going to tell you how to start out running a 200 hit...safely....and make power. I'd love to be your engine builder....

 

Make sure you got the tune on the motor right on the money before you even think of spraying any amount. Then I would call Nitrous Outlet since you have their plate system and seem to have never used nitrous before. They are very good people that will give you expert advise. The guys are right. Go right to the horses mouth. Eliminate the hear sayers. Just so you know if you were trying some secret squirrel stuff. You pretty much told everyone basically what your motor is going to put out and how much spray your going to hit it with, and a picture of your car. No offence. Best of Luck to You!!!

 

We use -8s on just motor and -9s on spray. But for your combo I would still talk to Nitrous Outlet to get their advise. You will be very happy you did.

 

Well yea I definitely took your post as it was written, don't see how else to take it...damn man this forum is typically helpful...the internet hardasses are really taking over everywhere.

I've been running nitrous on cars for 10 years. Every season from June until October. Not once have I caused damage, to any component due to spray... At all...on several different platforms. Including several stock shortblocks on over 200hp of nitrous, that I tuned in myself. I also didn't realize that by asking a very simple question of basically with this type of engine combo (thinking few of the other members on here have used it) what plugs worked best for them, that I'd have to explain to the fullest on how I am not a total moron and quite obviously wouldn't be starting right out on a 250 shot on a brand new engine/trans/rear end/suspension car that I literally am in the process of just finishing. Naturally I am going to make the car work on the motor, have the motor files tuned professionally because I can certainly accept my limits, and then work my way up to a healthy 200-250 shot from there. I am well aware of differing combos and cars change many things situation to situation, I just wanted to know what has worked well for others in the past...just wanted an idea to compare my setup to. Thank you for your advice (most of which I already know), but your delivery blows dude. I also only gave out some quick details on the motor to give an idea to those hoping to contribute to this post, I did not give out the trans or rear or gearing or tire, not the weight, or whether I'd be running 1/8 or 1/4... You can infer a very rough idea of what the car will do, but not very accurately. You're probably knowledgeable and probably would be helpful if you didn't treat people like they were idiots. Boredom and brainstorming while sitting at worked sparked my thought to post, which obviously was a waste of time in your eyes.

I'll probably fall somewhere right in that range also. Thanks for the info, this is all I was looking for, what has worked for others... Just ideas, not gospel. I appreciate it. My car is now quite a bit different than in my sig pic, that was the first year I owned it, almost unrecognizable compared to that now... but I get your point.

 

Sent you a PM.
