100% And don't let other people beat you down by saying you're going to screw it up. Every great tuner/car builder/engine builder/etc. out there didn't know a damn thing before they started trying things. Everyone can figure it out, but you don't learn by allowing everyone else to tell you what to do. A great engine builder told me "I started building my own engines, because A lot of people pay someone else to blow their stuff up. I figured I can do that myself." Guess what he got good at it and is now one of the top in the country. | |||

Chris, for setting your shift time, do you always keep the time the same no matter what the DA is on your weather station or what track your are competing at? Or do you vary the shift time you’ll use for an event based on what you figure the average DA will be for the day? I ask this because as the weather gets better or worse using shift time, the rpm that the shift "completes" at will vary accordingly… ie….. better weather shifts higher rpm, worse weather shifts lower rpm based on time. | |||

For it to be an advantage, your looking for a certain rpm dependent on your engines power curve, for the shift to occur. You might adjust the timer a tenth or two all year, no matter where you go,or time of year. If you have a IKE box with a run replay, you're uptown. You'll never look at your racepak or grid run graph again, during a race. With it you can scroll through the race rpm's in seconds, before you get out of the car at the trailer. A friend has a Mega 450 for sale, I took it out of the 496 third gen Camaro we transformed back into a street car. I'm 99.9% sure it has a run replay. $100 plus shippingThis message has been edited.

Same here, but lately both of our cars are set-up for time. I consistently go rounds & win races over the last 30+ years. It's working for me & I'll continue to do what the so called expert(s) think is wrong. 1980 Camaro Taking the Best Working Small Tire Shyt Box & making it Greater Than Before! 3000 lbs.

As with literally everything in this sport, you HAVE to try things and see what works for you and your operation. Our dragster shifts on RPM using the shift light output on the GRID and it is one of the most consistent cars on any property its at. Camaro is also shifted on RPM because it doesn't always have the delay box in the car to be able to shift it, its a car that can run any class practically. If we were to ever 8.90 the dragster, we'd simply wire it up to shift while on the stop (time), no reason not to in that instance but as of now, have no reason to run the 8.90 stuff so it's not even wired to do it that way..

Mike, I am interested in the delay box. Pm me the information on it. | |||

I've gotten a bunch of PM's, never sent one, not sure how. PM me, I'll message you back my phone number. It's a Mega 450 out of a Ray Miller dragster we replaced a IKE thumb wheel box in the third gen Camaro in 2017. The guy with the Ray Miller dragsters gave it to me for doing a bunch of work on dragsters his daughters drive for him. Works perfect. | |||

I’m sure you’re aware that with a Grid in Camaro you could shift on either RPM or Time. My Grid is set up for both Time and RPM shifting. I have an over-ride that I can activate during the run bypassing both these shift settings and shifting at a higher RPM setting if desired. This over-ride can be done multiple ways even without a Grid. | |||

Its rare we are changing the timer to shift, when you go from sea level to Vegas its a must or really huge air swings which are rare. I may change it to get closer to a number if needed more so than changing it for condition changes. | |||

A lot of good comments I guess a person just have to try whatever and do what is best for them | |||
