our local track just basically has you pop ur hood and shut it for inspections but world ford challenge might be a different story.....oh well i guess i could just buy some metal ones, no big deal
I have the NOS Sniper on my carbed 82. I have run just the 100 jets, but I really like it. I am still using a mech fuel pump, and it seems to run fine. It took about 6 tenths off my eigth mile, and I am very conservative about launching on my 7.5 axle.
It passed tech at Orlando Speedworld last spring at FFW. I did add a braided hose for the relief valve, etc.
I also added a bottle gage, fuel gage and bottle heater.
Overall I highly recommend it. I probably am not going to try to run anything more than the 150 jets that came with it anyway, so it seemed to be the best bang for the buck for me. NOS tech support was excellent.
I went from a 13.05 to a 11.56 in the 1/4 mile @ 1700ft. so if you are in the 12's or close i have no doubt you will be in the 11's. I'm hoping with a tune and a try at a sea lvl track to get low 11's.
