Dyno results 100 shot with graph
Dyno results 100 shot with graph N/a car put down 305/330 on 100 shot it put down 400/460. Pretty happy with the results.
Power falls off up top but it gets richer the higher I spin it. It ends up bottom 11s afr. I have .052(100hp) jet for nitrous and .031(125hp) for fuel according to my chart. Reason was having a lean spike right at the hit of mid 13s afr. Is there a way to fix this? This was also pulling 4 degrees plus having the knock sensors pull 1-2 degrees.

im actually running the exact same jets. we put the correct jets in for a 100 shot and it leaned out BAD up top..even started knocking! ive been on these jets for a year and i havent had any issues...im actually still running the same bosch platinum 2 plugs i put in her a year ago!
those jets on stock motor, stock 4l60e, stock 2.73 rear end, pacesetter LT headers, open y-pipe, SLP lid, and a good tune put me at 11.74 @ 114 (Albuquerque, NM - 5312ft above sea level)...should get out pretty good back in tennessee!
maybe not anymore...i just hit 162k miles!

You need to take more timing out if you are getting kr. Kr + nitrous = bad
You are right, I am new to this. Suggestions?
Yea I mentioned on the dyno. I was told it was because of stock 98 sensors were more sensitive. Im pretty sure I had the same issue befire nitrous, and on my old 98 car too.

I never made a clean pass at the track. Nitrous would turn off and on. I tried a 6400 pill in the window switch after the track and it worked perfect. Only thing I can think of is the 5400 and 5700 pills are to close to where the car shifts at 5600.
^agreed, pull more timing and do not rely on KR sensors as the Detonation is occuring and the PCM is pulling it back but having it even for one "fire" of the cyl to do that will lead to damage.
Still leave it hooked to the WOT switch, leave off part throttle, roll in at the 100 foot mark.

Hey sam sorry did not make it had 1 too many miller lights lol!!
Hope you get your kr worked out..You ever thought about a timing tuner so you could run max N/A and pull timing while on the jug?

With the 75n and 75f afr was in the 13s up to 4500rpm. How would that change with the 100n and 100f? I thought pulling 4 degrees should be good for this. How am I suppose to know if the sensors are just being the problem or if its really knock?
Once it start detonating it will keep doing it even if the knock sensor pulls a ton of timing it wont stop until you lift. So the key is to not let it start. Pull 2 more * out, 2* wont slow the car down. 13's unil 4500 then what? 12's the rest of the way? pull the timing and run it like that.
Launching!

Dude, before you blow your **** up...just call Tracey lol. Seriously...And what is your deal with these 98 ls1's? Aren't those the crappiest of the crap in terms of LS1 motors?
