This is on the car as it stands right now, AFR 11.0 duty cycle 88% on injectors, 11.6 large red tialsport wastegate spring. Previous log on the car resulted in a 63.43LB/min of airflow, maxing out the 60mm journal bearing turbo I have.
I previously replaced my exhaust gaskets as the kooks ones were completely broken, so I noticed a hell of a difference then. My exhaust has no leaks now. Previously, with my 8.7psi spring, I was only seeing 5…but this was due to leaky exhaust.
With that now fixed & my 11.6 psi spring in the car, I figured there would still be losses through the piping & intercooler……well…….
Well ladies & gents…. As I grab a pair of truly calibrated pressure gauges & hook them up, each from 0-10psi; one measuring crankcase pressure, and one measuring intake pressure. I take the car out for a spin and watch these gauges.
The Boost pressure maxes out the 10psi gauge….and the crankcase pressure maxes out the 10 psi gauge…. EEEEK.
What happened to pressure loss? I am simply running off the wastegate spring..I would have thought there would be a pressure loss. Are the springs manufactured with that much play in them?
Brought the car home, she has oil on her oil pan and coated various other places….looks like we are going to have to go SEAL hunting….
so now, we have a hell of a breather on the car, maintaining a .3 crankcase pressure MAX.
BUT we still have a SEAL problem.....

*going with twin 255 pumps, kit from lonnies performance (ordering within the next few weeks)
*building motor - nothing that we know of broke, ...besides the *********** spark plugs we had that the dick gave us at advance....don't want to risk it with these pistons & rods...especially if it goes it destroys the block...
*now running NGK TR7 plugs as per reading their documents, we are at about 400 RWHP N/A and about 550+ Boosted. It was an interesting read.
*Purchasing moser 12 bolt rearend w/all accessories
*Ceramic coating my 60mm turbo exhaust housing
*60#/hr injectors
*LS6 heads
Hopefully have it together & running again by February/mid-February.
Hopefully have it semi-broken in halfway through the year, bump up the boost to 12psi, get her on the dyno and see what we make. May even upgrade the turbo to a 67mm, as at this point I can guarantee I will outflow my 60mm.....I believe I already am...63.4LB/Min as of our last pull on the street.

ok ladies & gentlemen, with the onslaught of emails & requests I get for the STS manual, I'm going to have to stop emailing it. It has also been many years since they have first came out (my version) and their new version that has many differences & upgrades.
I recommend either requesting a manual or do something else. I simply cannot keep up & it is time consuming...with it also by now having had many changes.
I apologize for the inconvenience, however I would bet that someone has updated manuals or STS has a PDF version all in one by now...i mean get with the technology...LOL.
