Boostn7,
I did have to sit back and think about how and what order everything went down since it was a span of about a few months, but my last post is accurate. Hope this helps you out.

no i am just , saying there is a difference between 417@19 and 400@15 ..., the engine would run a lot more "relaxed" if you will @ 15psi , less chance of detonation and no need for race gas , thats all i am saying

Kind of surprised to hear the Atkin regulars are holding up when their own cryo'ed seals or even the "black seals" did not.

motor built and installed!
2 quick questions..
1. will having added the HKS twinpower and upsizing the intercooler significantly throw off the last tune?
2. In terms of Turbos what will be a suitable upgrade ( 400RWHP on PUMP! @ 12-13psi)

Now Ernie is switching to NRS seals
I've had Atkins before and it always breaks in the same spot the Tips of the seal
and it has ruined a few of my rotors/housings and a turbine blade
swicthed to RA seals and quess what? I have a dozen housings and rotors
collecting dust for several years now, since I have not had to change nothing
and those marks on the housings have had 0 effect of my compression or driveability....
as for a Turbo for 400rwhp @12-15 PSI
go with a PT-61 .96 for more top end or for maximum turbo responce go with a .81 P trim

Actually I havn't had any bad results with the Atkins seals, but with the amount of boost Im going to run this year, I thought it would be wise to upgrade to the NRS seals.

OEM is good for stock to mildly mod'ed , You break a seal
You could be replacing a rotor, housing and even a turbo
RA super seals and NRS and the like
are for people that want to push the envelope and will be refreshing the motor after a hard season
