You know devin, if you change your 15% drivetrain loss to around 5% the numbers are very close..
I honestly didn't think the r154 would be a 15% loss between all the parts.
I'm a turbo guy.. I've never done a burnout nor hard launch in my car so meh, you got more balls than me. Now I have done a 5mph punch and been scared shitless..:eek3dance:
Do you mean hood latch spacers? That'll mess with the aero a bit much. Could you 'in theory' create a vacuum from the air going under the car to help evacuate some of the hot air under the hood? I realize air under a car trying to race is kind of counter-productive but still..
Or you could try...
::popcorn:: I enjoyed the threads when this car was revealed as a stock turbo putting down so much torque and Devin defended him. Now the tables have turned!:evildeal:
It's staying normal under normal conditions because the CHT isn't climbing much but when you put it under a load the CHT's climb causing excessive coolant pressure. Sounds like you've got the very early signs of a BHG to me. I'd do as supraguy suggests and try to retorque.. Back off the nut...
Want to know common places to check for heavy rust? Rear fender wells if the plastic is still on and remove the spare tire and tap on it pretty heavily with your hand, leaking hatches cause rust to form there easily.
My only concern with running increased boost for a longer period would be heat soak inside the engine bay. I'd suggest wrapping the turbo cold/hot side in heat wrap along with a t4 turbo blanket.
First thing I see wrong with that list is no means of tuning. Please please please for the love of whatever religion you are, focus more on the tuning stability of the engine vs performance parts. All of those upgrades would really shine with a EMS.
As far as the size on the t4, it depends on...
