2022 NTRA Winter Nationals at Bear Creek Dragway SIGN UP

That would apply to any hot build Mike. Obviously running them at a lower voltage would make any car last longer. This Class has always run at 26v. It is an Unlimited Class after all. Not for the faint of heart. The higher voltage and amperage is necessary for the parts that are allowed. Part of the game has been durablility with this particular Class. This chassis was never meant or built to go this fast. We are overcoming boundaries of the chassis itself. This is the Top Fuel of our Classes. There are slower Classes for those that want their cars to last longer. The intent of the voltage is NOT to tear everyone's cars up and turn them into junk. The voltage itself puts limitations on the motors, downforce, and other things. It just isn't 4G Unlimited if it isn't run at 26v. I do all my testing at 26v. If it's not going to stand up to it in testing, it sure isn't going to during the race. 

It's been crazy Mike. The bar has been raised so much higher than I thought it ever could be. Gnome posted that he is in the .2's! That is truly unbelievable and a fantastic accomplishment on Jeff's part. I know he said that was without the body but that is still going to be faster than anything we've seen yet. But he is also seeing the limitations of the motor vs the voltage. I have said this before.......prior to 2014 the owner of the forum Sam Beckworth had a track in Colorado (Pikes Peak Dragway). There was another track there as well (Drag City USA). They both ran league racing and proxy racing. They both used deep cycle batteries that when fully charged were 27v with unlimited amperage. Everything ran at those voltages. 4G Unlimited and Mountain Motor Pro Stock (Inline) started at those tracks, Blacktop Raceway, and Bear Creek and have been extremely popular ever since. Talk about gears shredding.....that is some gear shredding power. But that's how it is done in some places. The trick of 4GU is to find that happy medium between lightning fast and making it through a race. The last couple of meetings have shown it is achievable. There have only been a few cars throughout the years that were truly damaged bad. One of those was mine and it was caught on camera. Most issues are pinions coming off, crown gear issues, wheels slipping, things like that. 

I agree with Dave these 4G Unlimiteds are like running a little nitro car. They’re hard to tune, they are hard to get to the tunable point. They’re unpredictable on the edge every pass and capable of blowing up at any time. I think that’s why it’s my new favorite class. I know there’s a lot of different thoughts on the voltage but I like the 26V it adds to the uncertainty the excitement the explosiveness to the class plus the challenge of making it live. It’s what Nitro does to the real cars. And I totally agree with what Jeff said... it’s not for faint. I drive a truck and have all day to think about stupid stuff. Was thinking about this today maybe something to think about for future races in this class. Giving the car owner or crew chief the option to choose what voltage he or she would like to run ? Have a maximum voltage let’s say 26V and you have the opinion of anything less. It would be like mixing Nitro how much percentage to run. If a guy has a car that runs consistent at 20V and lives but 26V kills his setup he has a chance to go rounds. And maybe could make qualifying possible ? Having the option to make a qualifying run or not ? You could make a safe qualifying pass on a lower voltage or lean on it at 26V. Place the car’s that made qualifying runs in order and fill the non runners randomly to fill the bottom part of the field , that way there would be less chance of two faster cars meeting in the first round. And it kinda gives a small preview of what your car is going to do on a unfamiliar track. The drawback would be more work and confusion for the racemasters. Just my thoughts🤪
One of my favorite quotes fits this class to a T...
“4G Unlimited Racing" Equals Hours and Hours of tedious  monotony punctuated by  " .3 SECONDS OF SHEER TERROR"

Now you know you cannot leave it alone.
We all try to get that last .01 out of it and of course it always goes
in the opposite direction.
My 4GU was only hitting 32 MPH @ 20V the ET however was in the low .4s.

This is great.  You guys keep making your 4GUs faster and faster.  Hoping this might be one of those tortoise and hare situations.  Provided of course the tortoise can complete a few successful passes.

Its always quiet when 4g unlimited is coming up.

I'll be coming in the race blind this time. I ordered more sensors for my track and was going to rewire it. Now we have a new track in the works , so I'm holding off on wiring the new sensors in and do it all at once. Doing the old school grab a fast car then tune a car to beat it or match it lol.
