"RA SuperSeal" ?
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.
thnx for ur feed back Anthony,
the problem is that I am stuck with 3mm option only,
next build I will give tham a try,
will give ra's a try for now with e85 and wi hope thay will stay cooler,
did u use a air filter on your turbo?
can debree from out side couse the marks on the housings?

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?
