...The NOS will only be used for the track. So in the end we expect to see +500 HP on boost only without NOS. At those power levels we will be maxing the injectors and the Tial wastegate. Bigger injectors will be installed when/if we switch to the AEM.
.I know in order to reach those numbers the e-Manage will be pushed to the limits too...... but ..............there is only one way to find out

Update:
We just arrived from the Dyno..
We have good numbers and bad news. We made 476HP at 7,400 rpm's running 21 psi of boost. This comes from a boost only tune and NO USE OF NOS!!!! We made those numbers using pump gas from the local Texaco gas station with 93 octane rating and using the e-Manage Ultimate.
You need to listen to the engine scream past 6500 rpms
...
The bad news is that we spun a bearing in the last run and that is why we had to stop tuning the engine and reach the 500HP goal on pump gas. We were 24 HP shy of that when the engine spun the bearing.
We will be checking the crankshaft tomorrow to see the amount of damage down there. Tomorrow me or ScionGT35R will post dyno graphs and pictures of the facelift the car received before going to the dyno
since it is 1:30 AM here and we are exhausted

do you think that could be one of the reasons the Bering spun ?

We didn't have a chance to buy VP fuel neither NOS so our first goal was unreacheable since we get to the Dyno yesterday. The car was making great #s but ____ HAPPENDS!!!!! We will be checking the car today and will post a couple pics later. Hope it could be repaired fast and get back to the Dyno with VP and NOS..EDIT: This post was written by ScionGT35R by error because I left the account logged in as I stayed in his home last night!!!!!

Well, We opened the bottom end today and found the root cause of the problem. The nut that holds the oil pump sprocket to the oil pump got loose and falled in the oil pan where it was sucked by the oil pickup tube.
You can see the nut inside the pickup tube here.....
This confirms what I said before opening the engine. The problem was caused by lubrication failure but not because of the higher rev limit as it was caused by the oil pump failing to work because of the nut that is supposed to hold it.
The sad part is the crankshaft is damaged but salvageable and the K1 connecting rods are OK. We will keep you guys informed of the next step as sonn as we decide what to do. We might resize the cranksahft or install a new one. We will see....
