I do plan on using nitrous but am curious how much my times will be effecting when I plan on racing only motor with a more nitrous specific stall.

So could you let me know when you switched to a more nitrous specific stall how much did it effect your times when you were just racing all motor compared to your all motor stall? Also could you let me know what kind of automatic and stalls you used? Thanks for any info.

well last year I had a cheap nitrous converter. Well not that cheap but an edge pro nitrous or what ever their higher end converter is called. I was running 10.5's on motor. This year I got a PTC converter set up for my car. I went 11.0 or 10.90 on motor with nothing else changed. What I can say is with the new converter I was able to leave on 350hp of spray and moved up a few notches on the fastest LT1 list.

So I guess the 2nd converter was better set up for your big nitrous shot compared to the first one and even though it hurt your all motor times it made your nitrous times better than your edge converter. Is this correct?

5000 stall Fuddle N/A: 11.35's 120-121
5000 Fuddle on 150 shot: 10.69 129+
3000 Fuddle N/A: 11.75-12.0. Better ET with LESS spark timing, slower with full timing
3000 Fuddle 150 shot: 10.40's 131+
4500 Vigilante N/A 11.30's
4500 Vig 150 shot: 10.30's 131+
4500 Vig 200 shot: 10.15 @ 133.6
28" to 26" tire: 9.85 @ 140+

All with a PG trans and from my what I can remember, no other changes. Same tire. similar 60fts. The 5000 was great on motor but flashed past 6000 on the hose. It gained NO mph on the big end compared to N/A passes. The 3000 was a joke. I had a hard time spinning the tires in the water box. I would spray it while on the transbrake and it would flashes just over 4000. 60fts went from 1.60's to 1.95-2.05. If I took 10 degrees of timing out, it would 60ft in the 1.80 range and run 11.70's vs 12.0-12.20's..

This 4500 piece works nice with 200hp jetting and looks like 300 will work alright also. We'll see! It was in a 9.0 heavy car with a good amount of hose and I got it CHEAP. So far so good.

Gearing also played a HUGE part. The tire change was more shocking than anything. Even putting my 26" Nittos on gained me 4-5mph and I had to baby those out of the hole.
