NOS....oh, you mean "noss"???

hehehe
I dunno, if they went the way that FlowTech did (aka BLOWtech), another Holley-bought-out company, I'd have my own doubts. I can't substantiate any claim with NOS either way, but I have been truly disappointed with FlowTech products. Another choice in the nitrous oxide stuff is CompuCar. I have one of their catalogs from Norwalk, and their systems seem pretty impressive. Nowhere near the size of NOS (they have Holley backing them for God's sake), but the guys at the CompuCar manufacturer's midway at Norwalk were cool. Just my .02 on this.
