"Bogging" in first gear

bushman66 · 06-06-2012, 11:30 AM

I will take it in, just to be safe, but I'm betting they don't find anything. I'm launching at say 2000RPM (not riding the clutch too much), then punching it. The "bog" is so pronounced that it almost throws me forward into my seatbelt, then throws me back into the seat when it "catches".

My twin turbo Porsche just accelerates smoothly off the line and its a turbocharged engine where you would expect turbo lag. The 370Z, being normally aspirated, should accelerate more smoothly than that. Really the best analogy I have is when we used to mess with 60's musclecars and Holley carbs, we'd get that "bog" off the line when you'd slam your foot to the floor and we would tune it by changing out power valves, jets, etc. until we got that smooth application of power. I'd never expect a modern EFI to bog like this off the line...
