Yup, probably going to try 125 next sunday @ the track. Not to sure how it will handle the 125 but if engine goes it would be good reason to finish series 2 and drop it in.
I really do not see a problem with it taking the 125 it takes 100 great. In total I have probably went through app 4 bottles with the 100 shot, that is alot of passes.

Curious to the reason you say it will only gain 10-15 hp over rated increase for the SC engine, I run 100 shot wet on mine and talking with Zoomer at ZZP and the guys @ Zex they claim sprying through the SC can yeild up to 50-60% increase. I have a 125 for the series 2 zoomer said I could expect to get 165-175 hp from the 125 shot.
The reasoning I was told was because of the intercooling effect the nitrous would have on the charge. I have the Zex system too and I figured the supercharger would stack a lot of nitrous in the intake and it would result (like you say) in a 100 shot being 150 or such. When I brought this up to Zex they went about explaining how it would be 10-15 from the intercooling effect. The thought stayed in my mind and IIRC I emailed Holley and got a similar response. This was years ago though. I'm VERY sure of the response from Zex though, I probably would have never purchased it had they told me 50-60% over.
Adding a supercharger generally raises the VE to over 100%. Guesstimate 110%. Thats maybe 30% higher, add in the intercooling effect and I can see where the 50-60% comes from.
But I'm willing to bet the rating is based on 100% VE. So lets say 20% of the volume of gas going in is nitrous. Stuffing it with 110% would only mean 22% of the total volume is nitrous. That would be 10% over the rated shot. Add in the intercooling effect and I can see where 10-15hp comes from.
So I've effectively debated myself on this issue. I really don't know.

hahaha..err, I'm sure whoever that is would but I think they're scared that if they throw a rod they'll end up buying a new head and block, which would suck...just a thought though.
