well if you raised the port roof, then you may alsoi want to entertain epoxy in the bottom f the port, most notably in the short side radius and shape that area to compliment the higher roof. plus a proper SSR will yeild gains as well
im in search of a wiper arm motor assembly/ mainly the electrical plastic box that bolts to it and houses the washer motor/ mine is internally failed in the circuit board and i cant find a replacment. lmk
thanks. cam
with a big turbine/turbine housing that makes (comparibly) alot less backpressure/ your wasegate approach angle becomes more and more important because your shifting your tubo's "control" away from backpressure and more towards flow.
fix the wasegate inlet angle, and youll fix your boost issue
your external gate wont control boost because that stock wastegate hole drilled into the side of your stock style turbine housing is at a HARSH 90 degree angle which promotes no flow through it/ you may have a killer wasegate but under power it stalls any "would be" wastgated exhaust and then...
Well you have to go by the afr gauge in your instance... And pull a plug at the end of the run to verify that your super rich. For the sake of keeping safe octane, probably leave the alky where it's at and pull fuel.
Not sure what you have for a chip in the car but most are setup for be rich...
I Always tune by the wideband and the look of the plugs.... For beginners sake, get your afr number to around 10.7 ish and from there adjust up or down to see what gets the most mph...
Keep the hell away from any knock and abort the run if your getting more than "trans shift noise"
