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.

How about a 1150whp stock bottom end hellcat to start of the weekend? This car was brought to us from Missouri for a max effort setup on his stock engine. We installed our cam, Kong 2650, Long tube headers , Fuel injection depot triple plug and play fuel system , FIC 2150 injectors , Jeff’s cold air intake and a Sipple max effort transmission. The cam sounds so good and the power is insane!

This is definitely the shortest dyno video we have ever posted! You’ll probably have to watch it a few times to appreciate it. 1902whp on this Hellcat Charger BEAST! On board this monster is a Aj Berge 426, Jon Sipple Max effort transmission, Hellion Twin Turbo 66/68 mm setup, Fuel Injection Depot triple pump setup on e90 and a Nitrous Outlet nozzle kit with a 200 shot. At 30 psi this car made 1690whp on boost , we added a 200 shot and it pushed it to an amazing 1902whp! This is a water jacket BGE block so we are stopping here. If this was filled or even half filled I’d push it well into the 2200-2300whp range with more boost. This gentleman has one helluva street car now !🤓🤣 I hope he is ready!

Happy Monday! After 13 years of being parked in a corner and 9 long months of getting Loco back together and updated to 2026 technology, she is ready to shake things up! We already have three big races locked in for Loco in June. Hopefully some of ya’ll will come out and support all three of these great events! I can’t thank Jon Sipple, John Urist( Hellion Turbo),Joseph and Chuck Lawerence ( Lawerence Engine and Machine), Aj Berge, Scotty Seals ( Pro Chassis and Fab) and Chris Dufresne for all their help in getting this OG car back out after 13 years of sitting. It’s a monster and I’m ready to shake things up with it. I’ll have another post soon with dyno videos and track videos ( sorry NT will be shown right now ). We are looking forward to having our own car back out in the racing scene showing what our shop and our partners are capable of!

Round two for this monster! This car was brought to us last year with a Whipple , headers and Fore Fuel System for tuning. It’s a full weight Charger and he wanted to see if we could speed him up in the 1/4 mile verse his other tune. We retuned the car and he dropped 4/10’s and gains 7mph! Fast forward to this year. The car once again came in for some goodies. While it was here we noticed the Whipple 3.0 was making ALOT of noise. Upon inspection we discovered it was unfortunately hurt. The owner decided he wanted to replicate all these cars we have been doing lately with our cam, Kong 2650, and Fuel Injection Depot Triple returnless fuel system. Since he is a hard core racer I suggested we go ahead and put a shot of nitrous on it too!🫣 It did exactly what we told him it would do. His goal is an 8 second pass at full weight and he definitely has the power to do that now!! 1114whp on blower and 1290whp on nitrous! Our cam coupled with the Kong 2650 consistently makes over 1100whp on a stock engine. We have made 1096whp with our cam on a Kong ported 2.7 liter as well! We have 4 more cars here now getting this exact same setup, they are here because not only do we make big power on the dyno, our cars are extremely fast at the track from our 26 years of experience knowing how to make that power work on the drag strip. Give us a call or send us an email if you’re ready to add more power to your Gen3 hemi! 770-449-6668 or [email protected]

How about a 8:30 pm tease?🤣. She is going vertical and should pull all the way to 8000 rpm. This is on 29 psi and it looks like it’s going to make around 1800whp on 29 psi and peg my dyno on 30-31 psi @ 2000whp. We will need to get it on a hub dyno to see what 40-42 psi does. Videos will follow as well as a chart taking the car to 8,000rpm 🫣🤓 &fab

Well guys, As yall know I dug LOCO out of a corner after sitting for 13 years and redid the entire car. Keefa put up a post about a blind lock in N/T shootout, no one knew what cars were in it until everyone paid. I was the first to send money!🤓🫣🤣Today the list was released. All of y’all need to come out to his event June 20th @ Darlington and watch this go down !

How about a Kenne Bell powered 2018 demon to start off today?! My long time and very close friend Tim Holmberg from Holmberg Motorsports made the 17 hour trip from Minnesota to Atlanta to spend the week dialing in his Demon to start out his race season at Street Car Braggin’ Rights . Tim built this bad boy over the last few years and it is absolutely gorgeous and so well built. The 1300whp is on boost only and the 1500whp is 150 of the 300 shot he has on his car. I didn’t want to spray the full 300 on the dyno, so we will save that to ramp in at the track as it’s needed. I can’t wait to see what this thing lays down in the 1/4 mile. Based on previous cars we have done with similar horse power, I hope he is ready for a 7 second pass and some serious MPH! Of course this power plant is backed up by a Sipple Transmission and our Fuel Injection Depot Plug and Play Triple Pump Max Effort system.

Ok 2015-2023 6.4 owners, we need a car. HP tuners is going to work with me to develop flex tuning for your cars. This may take awhile so I need someone who can give up their car for a period of time without a time line pressure on me and them.

There will not be any charge associated with this for the test car.

If you have a car you’re willing to leave with us for testing , send me a email at
