This beast is about ready to ship back to Florida. This is a stock motor car with our custom cam, IC chiller to keep things cool, Kong 2650, headers, triple pump fuel system , and a corsa exhaust. The car is tuned on pump e85 utilizing our flex fuel tuning so it will self adjust for the ethanol content and also allows the owner to use 93 octane when he can’t find e85 on a road trip. The stock transmission isn’t going to last long in this beast so he plans to send it back to us in late July to add a Sipple Max Effort transmissions. I seriously could have pushed this car for more power , but with the stock rods we stopped once we hit 1200whp. This combo has become very popular and we have a lot of cars here and on our schedule for this exact combination. If you’re looking to step up your power on your Dodge car, truck or SUV, give us a call at 770-449-6668 or email me at [email protected]

There are cams that chop and then there are cams that CHOP! This monster has been in hibernation for a few years and I think we need to talk Danny into bringing Roxy back out and show everyone why it was THE heavy weight champ! This beast makes BIG power with its 4.9 liter Kenne Bell and Nitrous outlet kit.

This gentleman drove 11 hours for us to tune this car he built in his garage. He did a fantastic job on the build. The install is super clean and it made big power! The car has an older generation Whipple 4.5L, MMX long block , Fore Fuel system , and a Sipple Transmission . It’s tuned in pump e85@ 24psi using HP tuners. 1200whp should be enough to keep him entertained for awhile 🤓

brought us is super nice 2016 Hellcat for some upgrades . He decided to go with our custom camshaft and True Flex fuel tuning. Our flex tuning allows him to run 93 octane or e85 and the car self adjusts for the fuel . The car only makes 13.6 psi ( he wants his power increased in stages ) and it put down 888whp on 93 octane and 949whp on e85! It’s sounds soooo good too! If you’d like to add more power to your Dodge or you’re interested in converting your current setup to our true flex tuning, give us a call at 770-449-6668 or email me at [email protected]

Happy Friday!
We are back at the shop after a long week of testing. This was the best test session I have ever had in my 27 years in business. Loco came right off the trailer and went a PB first pass! We didn’t have to make any repairs, fix any broken parts , or even make any major changes. The car absolutely blew all of our minds . Scotty had the chassis set up so well that the only change made the entire time was we took two clicks out of the rear shocks rebound. It never spun one time , never tried to wheelie and went straight as an arrow every pass. We were able to completely concentrate on going faster every pass. We are going to make a gear change because we aren’t happy with the high gear rpm thru the traps. I can’t thank Scotty at Pro Chassis and Fab enough for what he did with this car and spending two days with me combing over data, making decisions and changes to really make this car fly. Lawerence machine built me one hell of an engine! The Sipple built glide performed flawlessly! The Pro Torque converter is super nice and doing its job very well. It’s so nice to have the OG car back out! I’ve attached two videos , one is just the burn out of the 4th pass and the other is the 4th pass. The 60’ is INSANE and is going to get even faster. There are no times posted obviously because this car is running in a lot of NT events this year.

Loaded in the stacker for two days of testing at Steele. We have Limecat and Oscar with us too! The shop is closed until Friday, but Rhonda will be on the phones and I’ll answer emails each day before testing starts. We will have plenty of videos to post up at the end of the week.

The OG is loading up in the stacker for next week’s two day test session. Here’s a quick little test before it’s loaded of a 4700 rpm two step, with a third step dropping it down to 4200rpm. I did a little bump test too just make sure everything works correctly. We have three N/T races in June, so we are working on consistency with this car next week. I’ll post up the testing videos next week once we are back. It’s going to be a fun year with this thing!

We have a HP90 twin Turbo hellcat that thinks is a Coyote Mustang 😁🤡. Hellion Twin turbos, 8000+ rpm revs and a whole lot of powa! We finally got this valve train to live after a few months of busting parts in it with our high rpm goals. It will definitely be looking for some races in June. Do ya think we will get any O/D hellcat takers or is it gonna have to race with the O/D mustangs? My bets gonna be mustangs , those boys aren’t afraid of a fat cat and they don’t have a list of stips 3 pages long. Huge thanks to Jon Sipple for the new transmission setup to let this hellcat show off next time it’s out! This converter is the bomb! Man it lets these turbos come on sooooo fast and couples just at the right rpm.
