Yes it works good as long as its tuned for the N2O- Xtreme RC Cars magazine put one on the dyno to see what N2O will do and at first they didnt think it would work. That is till they tested it and it did make a gain now they didnt say how much of a gain it had but it did have a gain in power.
And I can say that it has a good gain and was worth the money to me but then I only paid $45.00 for it new....
