let me say first, that ive read the sticky about nitrous on stock ls1 block, and ive searched for other posts.

current set up. 99 firebird fire hawk 6 speed

patriot 5.3 heads= https://www.patriot-performance.com/...&cat=36&page=1

ls6 intake

kooks 1 3/4 LT

comp cam part number 54-000-11

in/ex lift 571
in/ex dur 228
lsa 114


right now its kind of a sleeper cam. cant tell it has one. dynoed 405 whp

car was tuned by speed inc, near chicago.

so i was thinking about doing a 75 wet plate shot.

i was wondering if i can do this without pulling timing, ?

i realize that i have to change plugs.

i will have a button on the shifter and only be hitting it in the higher rpms when needed.


i also always go up a fuel jet or two



any advice would help greatly

 

Odds are when the car was tuned it was tuned for the best N/A performance. I would contact speed inc and ask the tunner, but odds are yes you will need to pull timing. You may look into a lingenfelter controller.

how much timing would i need to pull? i know all cars are different but, is there a general starting point.?


thanks

 

also about the controller. ive looked on their website and i cannot find what your talking about.

i know msd makes one . will that one do the same job>?

 

Don't knock that cam, when I was building a stock cube engine I had a 228R cam, I currently have a Tourqer 2 in a TSP 404 cuin motor, it's nothing to laugh at NA... 10.9x full weight and has the potential to go faster, it will be a single digit producer on NO2. Small Cams Love NO2!


You will have to pull timing in one fashion or another, Check with your tuner... it sounds cheesy but the NO2 sponsors have been the most help full people I've dealt with, even when I start the conversation "I'm not going to buy for a year, just planning and window shopping".


BTW: Just plan for a 150, start with 100, even numbers of 50 are the easiest to deal with and usually come with the kits.

 

so this weekend i went ahead and put a kit on, running a 150 shot with a window switch, seems to be running good, so far>>>

 

also when i installed everything, i put it where you wont see the bottle or switches by looking at the inside of the car.

 

How much timing did u wind up pulling or did u just take it to ur tuner and have him go to town

 

i ended up just pulling 6* for now , i have to further log it. afr seems good for now too.
