Sounds exactly what my 07 SC does.....So it's time to ask the question I've had on my mind since my first street drive. I suspect something is wrong ... my mind tells me, maybe a vacuum leak, but I don't know enough about turbos and engines and whatnot to say for sure.
My boost gauge, under light or no acceleration at all, reads between 20 and 30 VAC. In moderate acceleration, it reads between 5-10 VAC. Only during heavy acceleration, does it ever get into the positive PSI range (5-10 under heavy acceleration, until I approach red line, where I've seen it spike to 20 PSI once or twice). Is this normal?
My engine idles perfectly. It revs up in RPM's perfectly, it doesn't backfire, and it seems to have plenty of power. But without having driven or ridden in another Goblin, I can't say for sure. I know the car can make you feel like your teeth got knocked out of your mouth (my wife's description), but my mind keeps wandering back to the boost gauge.
School me!
Not sure, going to have a look at it this weekend.like this?

Maybe my question will help us both then.Sounds exactly what my 07 SC does.....
This sounds normal. Boost pressure will correspond to load and RPM. A first gear pull, with the short gearing is a light load.So it's time to ask the question I've had on my mind since my first street drive.

Call it a research sabbatical........Thanks for all the replies, guys ... as helpful as ever! I won't be driving the car until my ankle is better, but I'll observe some more then.
