Well the car hit a couple of snags while tuning on Friday.
1st off... We ran off the Tial 44mm WG spring, and only saw 10psi. (I was under the impression it would be more like 13-14psi?) Then later we hit a oil pressure problem, with the pressure being WAY too high. like 100psi at idle! .
Sooo......
Friday my car hit the rollers for tuning with a bunch of new stuff. Mainly the FP3065, FP2x cams, and AEM EMS w/ MAP. We started out tuning with Waste Gate pressure that we thought would be .9 Bar. But strangely we could only hit a rock steady 10psi. (Maybe it was a smaller spring than we thought? I still had my catalytic converter on the exhaust, and the general consensus was that it was creating enough back pressure to blow the WG early.) We decided to go ahead and work with the 10psi to keep things safe; after all It was the 1st tune the car was seeing since all the upgrades. After a little playing around, the last run at 10psi net: 268AWHP. Whaaaa? 268awhp @ 10psi nice!
We were all real happy, feeling that 268 was a damn good number at 10psi. So we were ready to turn up the boost! We set it for aprox 15psi, and waited for the car to cool down. After things cooled we started her up and were just about ready to make another go when somebody started yelling SHUT IT OFF, SHUT IF OFF!!! (awh jeeezze thats never good to hear ) ......underneath the car there was oil everywhere! Luckily it wasn't the engine, but it seemed that the oil filter had backed off just enough to let oil spray everywhere. We got that fixed, and noticed the oil pressure was through the roof! Like 100psi at idle! It almost seems like the oil filter housing is clogged or something? We didnt dare keep tuning with all that pressure. So it got towed back to the shop. Its going to get pulled off and looked at this week. We know the housing has over 200miles on it. Its the original housing. I'm not sure what it could be. It sure ain't a bad oil pump thats for sure!
~Does anyone have any idea's about the super high oil pressure? Where I could start to trouble shoot, Or what could cause such a thing?
Overall the outcome was kind of a bummer, but I'm happy with 268awhp @ 10psi. It shows nice potential for whats to come. After things are straitened out, we'll stop somewhere between 350-400awhp with the stock block set-up. The Catalytic converter will be taken off too (I originally planned for the car to pass emmision, but the FP2x make that impossible). OHh the FP2x are Real lumpy; Just plain NASTY! Idle will have to be 1000RPM+, but OOoohhh ME LIKIE!
