Mission accomplished! FIRST HPATTERN STICK CAR TO RUN 6 SECONDS - 6.90 @ 194 MPH

Orange man bad Supra 6 second quarter mile

After 11 years of 6speed drag racing, this is a defining moment in not only my history but also world history. There has never been any other H-Pattern stick car to get into the 6 second zone... and I am still in shock that we were able to do it.

We have made such incredible progress over the past 18 months with this car. We got it all started by running 7.68 @ 200 with a standard diaphragm clutch. Then about 6 months later 7.20 @ 206 and 7.17 @ 207 in Florida. Then in March 2020 at TX2K we ran 7.05 @ 207 (twice), and a 7.00 @ 208. The 7.00 pass took the overall Stick/Hpattern record from Boostin Perfomance's Eclipse, the infamous Red Demon. There are a lot of other good, low 7 passes in the mix but I am just covering the highlights.

Now with this 6.90 @ 194 pass under our belt we have become the first ever H-Pattern stick car to run in the 6 second zone. YES... 194 MPH, the car actually shut off at the 1000-1100' mark, so there was room for more ET on this pass. We are still investigating the cause but it is something electrical.

As I write this, I still can not believe we were able to do this... A year ago I would have never thought this was possible, but with a lot of determination and the best team out there all of the stars lined up and we got that "perfect" pass.

Here is a quick rundown of the car:
Grannas GR2500 billet (Bullet) Engine package
Grannas GR1000F Supra T56 Magnum kit (Liberty faceplated 1-4, Browell Bellhousing)
Grannas Ultimate IRS rear subframe, Ultimate anti-roll bar, Ultimate LCA setup
Precision Chassis Inc. 25.5 chassis
MOTEC "ProDRAG" M150 by Prospeed Autosports / Chris Delgado
The Driveshaft Shop 9" rear with carbon fiber driveshaft
Precision Promod Turbo (102mm)
VWR Promod manifold spec'd by me
Headgames head
GSC cams
Boninfante Adjustable Titanium clutch
MT 28x10.5 Pro Bracket Radials

I always said watch out if I built a "real" race car... Previously I was too caught up in trying to be a street car. I did well, but nothing like this car does. My white car previous best was 8.17 @ 183 on a SYNCHRO manual, which is no small feat... But the orange car was brought to life and developed for one mission. 

The car got the name "Orange Man Bad" because I set out to do one thing, defy all odds, overcome IRS suspension, and 183 cubes... and go all the way to the White House... The "Commander in Chief" of all stick cars.

While I say the car is a "race car" at the same time, it actually is kind of simple setup. It is still using all the factory suspension pickup points, and it retains the the IRS rear suspension just reinforced with my tubular "Ultimate IRS" rear subframe setup. It is NOT a solid axle, back halved or a 3/4 chassis car. It is a factory unibody car, still has the factory floor, frame rails, factory body (doors/fenders/hood/hatch/front bumper are carbon fiber bolt-on replacements) reinforced with 25.5 chassis and a tubular front end. The chassis and body itself is 100% still a MKIV Supra. The car weighs 3000# with driver. These cars are heavy in factory form, 3600#.... so it is not a featherweight like some people think.

TREMEC T56 Magnum-F vs Regular magnum - installation in existing GR700 supra

Tremec Magnum-F vs T56 Magnum

My good friend and customer Ryan Scott recently upgraded his GR700 kit to the new Magnum-F transmission. I asked him to highlight the difference in shift experience/feel between the old kits with the Sikky shifter and the new Magnum-F kit I offer. I think the results speak for themselves!

I also asked him to demo the new bluetooth transmission harness product I offer which allows control of the reverse lockout based on speed, and also converts the transmission speedo sensor signal to work with the factory dash/speedometer. All in one nice clean harness which is as close to plug-and-play as possible. All of it controllable and customizable through a smartphone app. This replaces the old way of doing it with the pigtail kit and the SGI-5E or SGI-100BT box.

Here is the video below from Pure Function on youtube.


If you have a current Grannas Racing kit and want to upgrade, there are a few things you will need to change in addition to the transmission:

  1. The Magnum-F Transmission
  2. Driveshaft (magnum-F requires a longer driveshaft)
  3. Shifter (my new magnum-F shifter)
  4. If you are an original automatic MKIV, and used my tunnel cover product, you will need my new magnum-F version tunnel cover. The magnum-F requires a little more trimming and a slightly larger cover.

Contact us if you are interested in a kit, or interested in upgrading! I offer special pricing to return customers!

13B and 20B Rotary T56 Magnum swap kits for the FD3S - Updates

After test fitting a Tremec Magnum-F, along with some other R&D on the FD3S rotary chassis, I have updated my current rotary T56 Magnum kits to now only use the manual version bellhousing going forward.

The manual version bellhousing uses an FC3S starter, which mounts rearward towards the transmission. This setup works better for all applications and makes it simpler to manage on my end. This also was done out of necessity, due to the most 20B swaps engine mounts not allowing the automatic starter to fit at all.

The manual version bellhousing will fit both an auto rear plate or manual rear plate, so it only makes sense to do one kit.

The only downside to this style kit is the fact I have to take extra time to machine the magnum trans case to be able to fit the starter. This adds some extra labor costs, but in the end you end up with a beautiful bolt-in kit. See the pictures below showing where I machine the magnum case.

Here is a video of the installed transmission:


The only bad news, is during this recent R&D I found that the new Magnum-F transmission does not fit well in the FD3S chassis behind the rotary motor. Unfortunately, even though the magnum-F shifter is further back, it still does not sit back far enough, and you would have to cut your tunnel at the front of the shifter hole to clear (see pic below of me trying to test fit a Magnum-F in the FD3S).

Magnum-F Mazda RX-7 FD3S RX7 FC3S Rotary 13B 20B LS1 LS3 LS swap

Tremec T56 Magnum-F Magnum FD3S RX7 fitment tunnel LS LS1 LS3 LS7 swap T56

The downside to this is an extension shifter will still be required. There is no sense in paying the extra money for a Magnum-F, and then still pay for and have to run an extension shifter on top of that. It is cheaper to run the regular magnum and billet relocation shifter setup (Sikky).

Orange car comes back out swinging at FL2K

The Grannas Racing "Project H-Pattern" aka "Orange Man Bad" Supra came to play at TX2K with the goal of getting the car to leave the line more consistently. This consisted of adding a "long style" clutch to the mix. This is basically an adjustable clutch which allows you to adjust the weight and pressure on the clutch to allow it to slip on the line. I enlisted the help of Cale Aronson, a former Pro-Stock racer who now runs Black Magic clutches. Cale helped setup a new prototype 2JZ long-style clutch for this car as well as help dial it in at the event. 

The plan was to use FL2K as a test session to get the car short tracking and dialed in for World Cup Finals - Import vs Domestic the end of October. Thanks to Chris Delgado's tuning and Cale's clutch knowledge after only 4 passes we got a new personal best of 1.21 sixty foot and a 5.0 eighth mile... And what is really crazy is, on that 5.0 1/8 mile it broke the suspension on the launch and i was dragging the drivers rear tire in the wheel well down to through 3rd gear. If you watch the video below you can see how the car was swaying up top due to pretty much no control over the drivers rear wheel. On the next pass the clutch was slipping hard up top, and we ended up not being able to get it done on both ends of the track, and ended up getting knocked out first round of eliminations.

I have always struggled with getting this car to leave, so now that we have that straightened out, I have really high expectations going forward. Can't wait to see what the car will do at WCF! See you there!

Big thanks to Bullet Race Engineering, Prospeed Autosports (Chris Delgado Tuned!), Brian Roche Racing Engines, The Driveshaft Shop, Headgames Motorwerks, GSC Cams, Black Magic Clutches, Precision Chassis, Liberty's Gears, Browell Bellhousings, Tremec Transmissions, Virtual Works, Powerhouse Racing, Schmuck Built LLC, Buck Performance, and anyone else I missed!

Grannas T56 Magnum GROUP BUY 2019 has started!

The 2019 Grannas Racing T56 Magnum transmission group buy has started, and this year it is featuring the new Tremec T56 Magnum-F. This puts the shifter in a more ideal location for almost all my swap kits (other than MK3 and rotary powered FD3S rx7's)

This means NO MORE RELOCATION SHIFTERS! Smoother shifting, and no additional shifter to purchase. This means my kit prices have DROPPED! So that is great for everyone!

Here is the link to the group buy page, any questions please contact me.

In the video below at about 4 minutes I show the magnum-F in my supra and show the shifter feel!

The White Monster 6-Speed Supra Returns - Rebuild Part 1 - Motor & Suspension

I did a video documenting the first part of the rebuild on the white Supra. I also included some video of some of my favorite passes at the beginning to build a little hype and a little inspiration for myself to get this thing ready.

Grannas Racing 3.4L Stroker 2JZ-GTE

In part one, I will be covering the assembly of the motor, cam install, and suspension install. The motor was built by Brian Roche Racing Engines, and consists of an Eagle 3.4 2JZ crank, Callies rods, and diamond pistons. The block is 3/4 filled with epoxy, which retains streetability as well as adds strength to the casting.

The suspension consists of my Ultimate IRS stock replacement chromoly tubular subframe, my adjustable lower control arm setup with eyelet shock mounts, strange double adjustable coilovers, bucks performance upper adjustable arms, and figs performance adjustable trac arms and figs toe arms. The rear end is a Driveshaft shop 9" setup. 

Please subscribe to my youtube channel for part 2 of the video, as well as other informative videos and Supra content!

MKV Manual transmission option coming soon!!?

I really think the MKV is going to have a manual option soon, direct from Toyota/BMW. While doing R&D on a T56 Swap kit (T56 Magnum) for the MKV Supra, see what I found that makes me believe a manual is coming in the below video! Don't forget to subscribe to my channel for future updates, and other Supra related content!


Also in this short video I install a Titan Motorsports downpipe and Protune piggyback ECU on my wife's MKV Supra Launch Edition. These two parts are super easy to install and add about 100WHP for less than $900. You can not beat that in bang for buck. These cars respond really well to light mods, and I wanted to give her a little more power to play with.
