Hello all,
Just ordered my first kit due to the great sale from nitro dave's!!! Got the plate kit and the freebies, and lastly a FPSS!! I have a couple questions now that I cant seem to find a direct answer to....Im going to do a 150shot maybe only a 100...So....
What spark plug should I use? And gap?

Should I pull out any timing? How much?

Anything else I should know before I hit the button?

Thanks

 

Dont get scared! I just did my 75 shot today. Awsome! I have not messed with the timing yet but not going to go any more before i find out for sure. One guy on here said he was doing a 200 shot on stock timing. My car means to much to me to go that big.

 

Yeah same here...car means a lot to me!!! Thats why Im trying to find out as much as I can so I dont blow anything up....

 

I am going to be spraying for the first time as well. I am going with a 150 shot and wanted to know what I need to change to run that shot on the engine without blowing anything up.

 

Anyone????

 

Stock timing on a stock motor will handle a 150 shot all day long. Now for the ones that have had tunes I would check and see what timing you are running because most tuners advance the timing on N/A tunes and that could lead to problems. Usually u take about 2 degrees out for every 100 hp. Tr-6 plugs are what i prefer. Others prefer Autolites its just personal choice. And I would gap at about .035. Hope this helps.

 

I pull 5 degrees for a 150 shot

 

Is your car stock internally?

 

I disagree with this statement somewhat. We just put a kit on my buddys car, a 98 TA. His car stock was runnign 28 degrees of timing up top, and knocking like crazy without the spray, just the factory tune. We ended up at 18-19 degrees of timing up top before it was KR free. We got the motor running kr free at 23 -24 degrees, without the spray. So we ended up pulling 5-6 degrees up top. Just what i expierienced with the 98. A good rule of thumb is 2 degrees for every 50 HP like said above. Also, the TR6 plugs seemed to work great, with a .035 gap. Oh, we were also on 93 octane pump gas.

 

That car had problems already if it was knocking on a stock tune.

 

most cars i have scanned with stock tunes, have some KR

 

Thats interesting ive never came across it scanning.

 

So with timing do I pull some or no?? Some of you guys say pull it other say not to...Should I just have some dyno pulls done and see how the a/f turns out and the knock and what not??

 

if it was me, I would pull timing, like I said earlier, a good rule of thumb is 2 degrees every 50 hp to be on the safe side. Also, MAKE SURE you have TR6 plugs in there, wiht a .035 gap

 

I sprayed 100 shot a number of times on the stock tune and didn't have any issues at all. From what I've read, the Nitrous Outlet jetting is a little on the rich side to keep it safe. With that said, I've now got 4 deg of timing pulled and am thinking about going 150, since I just got a clutch that can handle it. 100 shot should be fine on stock timing, but any more than that, I'd probably get a tune.

Good luck!

On the stock tune, I was good to 100 shot. Above that I pulled 3° and that worked to a 175 shot.

A handheld like a predator or logging with HPT or EFI live is helpful in determining what will work with your combo.

 

Topic starter. lets start with a rundown of current mods and driveline. then we can make some recomendations on what to do to keep it as safe as possibel while making as much power as possible LOL.
