Before or after it ran lean and melted everything?

I can't see it being that much faster. The most you could really get away with without a tune would be a 16G with stock injectors -maybe 550s, and it most likely wouldn't make the power it should because of the lack of ability to change the fuel and timing. Maybe subtract .5 secs from a good stock time.

I am intrigued why you would ask this. Any back story?

Alot of stupid people in Central IL think their cars are all that with JUST bolt ons. They claim to be able to take a Corvette from a stop. I wouldn't know because I have a built motor and I've always have been tuned so there's no wasted horsepower.

I would say a absolute maximum of 300hp without a tune. Just tell them they might have "danger to manifold". I wouldn't waste my time with them. from your one picture it looks liek you actually put in the wrench time. That being said, as long as they aren't complete idiots it is nicve to have some fellow DSMers around.

Tell them to bring you a time slip.
