No it ran real sweet, rather boring really, all I noticed was that it was all over a bit quicker than usual. I used to run around 12.4's@108 N/a on 98 octane at 36 deg total. I only came back 2 deg, hit it off the line as well and went 122.8, tbh 110/110 was extra safe on the petrol side on those kits as std. back then!.....the chassis was up to it on leafs. A .051 jet was only 125hp if I remember right on the cheater kit, thats half of what I ran, was yours a bone stock motor?

Having a seperate pump for N20 is the biggest important thing you can do, although for 100 shot its not necessary, but it IS when you step it up!!
