Urgent Dyno Question
Im getting my car dyno'd for the first time this weekend. what RPM should i take the car up to without doing any damage. i want the best HP reading but do not want to brake the motor trying to find out. From what i see the typical is 6000, will that probably be enough, or should i go less at first then work my way up?

The dyno operator usually has a helper who drives the car and you get to watch.

Here's an old pic of the C4 on the dyno. It was raining that day. It was an F body club dyno day. I felt so out of place and was very nervous. I put up some pretty good numbers and was happy at the end. The guys on the left are not associated with the dyno operator. They were just marveling at the paint on my C4 and how the water beaded up on it.

I must admite I beat the poop out of my ls1 ws6 ALL the time and a handful of times I've totally spaced off and forgot that i had a m6 and forgot to (haha i said **** before I corrected and typed in shift) shift and it hit the rev limiter BIG time. Don't worry about it man. ls1's are made to take abuse. It's not going to hurt your car at all. Man you sound like my friend with a DOHC 4.6 mach 1 who is afraid to take it above 3,000 rpms and those rev to 7,000!!!

minority opinion here: we baby our c5 (except for every now & then on x-way on ramp
). not sure i care to have it on a dyno. every time i see a dyno photo, i see those 2 straps on the rear of the car & wonder if they'd do anything if by chance the car took off. anyone ever heard of that? bub

I saw a car take off in a vid once but it was putting down 1500rwhp some insanely built old style hotrod setup. Damn thing was 6 feet off the ground (dunno why they had it up that high lol) and it almost flew off.

I have seen only once where the vehicle was 'hurt' by ruining to the rev limiter.
This was in Bowling Green (CI VI).
A brand new C6 was on the dyno. ran it us - and holy smoke, the electronics in that baby went away!
Funny for the onlookers, not so for the owner.
Unless you have other issues with your Vette, having it dyno'ed by a reputable tunner is really not that all of a problem.
