I have a ls1 heads cam boltons 42 lb injectors with a 255 walbro pump w/ arp rod bolts. t56 built 12 bolt rear with 373's
On motor it made 425.
I have a nitrous wet outlet 92 plate kit. .
On a 100 hit it made 530 whp.
I used the suggested plugs and gapped them to what nitrous out let calls for.
My nitrous tune...is my all motor tune.

Well. My friends have talked me into a 150+ shot (depending how my fuel looks like).
Well I do a lot of all motor pulls and rarely get up on the spray.
But I really liked the idea of the lingenfelter LCN-2000 so I can retard my timing. For various shots ( 100,125,150, 175 ) .

I've been on this tune now for two years and would like to go back to a solid motor tune and use the box where we see fit.
Any unforeseen problems?
I also Am going to put new plugs In it before it gets on the rollers. Again before I used what was recommended and gapped them accordingly. Should I consider a different gap since I want to bounce between shots.

Note:
I say now I want to bounce between 100 and 150. But I'm sure I'll probably just leave the 150's in.

Any thoughts.

 

 

What plugs were you using before? The BR7's gapped around 30 to 35 would be best. I run the LNC-2000 and it works great and pulls the necessary timing when spraying only

 

Normally you want to go 1 step cooler plug per 100hp. NGK makes a 7, 8, and 9 heat range plug for the LS. I would start with your plug gap around .034. You will know if your gap is too wide if the nitrous starts cutting out when you make a hit, this means you are blowing out the spark. If that is the case I would close the gap up to .030-.032.

As mentioned above, I would run the BR7 plug for anything 100-200hp worth of nitrous.

The lingenfelter box is handy to have because it lets you pull timing on the fly, and only when the nitrous system is armed. I would pull 2* per 50hp to start with and tune back into it.

Let me know if you come up with anymore questions!

Thanks,
Garrett

 

I was using the ngk br7 ef. Gapped around 35-37 I think.

I see they come out the box at .032 I may just leave them alone.
Any problems with this for my all motor tune/pulls.


I will do about 90% all motor and about 10% on spray.

 

I am Running an LS2 404 ci motor with a 150 shot, BR7EF Plugs, Pulling 6 Degrees of timing out with the LNC - 2000 Timing Retard. Single Walbro 255 LPH Fuel pump. 42 lb. injectors.

I also Run Sunoco 100 Octane & 91 Octane @ 50% mix. I use the Fast A/F Ratio Monitor with Dual Wide Band Oxygen sensors to Tune my Camaro.

Occassionaly Data Logging Full passes at the Drags to check my air / fuel Ratio.

I Run my A/F Ratio on the Rich side 12:1 with No problems.

 

.032 Is just fine.
If you come up with any other questions let us know!

That's going to work just fine.
