Hey guys I have a Formula 303 Sr1 with twin 502 EFI's and Bravo 1:36 drives, currently twisting 23 Mirages, Wondering what you hink a set of plus's will do, same size, or should I jump to 25's, currently if I go for gold it spins 51/5200 rpm's I think I want to be below 5000 r's, best ever is 77 on Gps, pretty much always runs 74,

thanks

5200 goingb77 gives you under %8 slip..... That's darn good. You can get sets of 25+ darn cheap if ya keep an eye out.... I would give it a shot if your not having a problem hitting the limiter

Testing the 25 M+'s makes sense. You may need to Lab Finish them to get where you need to be.

Hello,

The Mirage Plus as the name implies, has more cupping than the original Mirage and will generally turn 200-300 less rpm in the same pitch. If you go to the 23" Mirage Plus's, your rpm will drop 200-300 anyway. The other option is to find a good used set of 25 Mirage's, not Plus's.

thanks guys I may have located a set to borrow, and test out

Let us know how it works out
