Enzo has been using them for quite some time as well. Ernie is now using them. A lot of the builders in the NE are using them too. I recently pulled apart a motor that had a few thousand miles on them and the housings looked excellent. I've been using them for about a year and had quite a few events and hard dyno passes. I've used them on gas, E85 and Enzo uses them on menthanol. This is probably my first post on these seals, I waited until I was 100% confident in them before I posted.

The fastest 13B in the world "La Otra" also uses these seals. I have asked Roan numerous times to post about them but he wants his customers to post their feedback so here is mine....
Ive personally ran water/meth with RA superseals. They still left the striations in the housings you could feel with your fingernail after only 5-6k miles of use. This was with water/meth, premix and a functioning OMP. Ive said it before, they are a great seal and forgiving especially for the price, however, there are better options these days for those who want power and reliability.

Roan sells the seals from www.rxparts.com I also use them exclusively now. I started doing engine builds and use them on all cars, street or race. I have not had a single motor come back for any issues. (...) I recently pulled apart a motor that had a few thousand miles on them and the housings looked excellent.
However, after 40-50k (hard to say, had speedo gear failure for a while) the rotor housings are in horrible shape. Deep circumferential grooving.
"A few thousand miles" is a month of driving for some people

What seals were you using that left the housings in horrible shape?
