If nobody checked, could be the factory rail stop location may not be effective after faceplates are installed. I shorten up the slider travel distance in the Toploader when I install the dog rings on the gears. When Liberty faceplates a Toploader, their slider travel distance is quite a bit...

I know just about zero about a DSM transmission, so I don't know if something like the shift rail stops I made for my faceplated Ford Toploader 4spd could help soften the hit on your shift rail ends.With a faceplated Toploader, adding shift rail stops keeps the inertia of the shift rails from...

A Hitmaster equipped AWD car just took home the $10K Stick Shift winner's check at the Tx2k23!

...SpeedFactory is using my Hitmaster to control the clutch during launch :)I consider mph to be a measure of power-to-weight, SpeedFactory's ability to post comparable ET's with 15 less MPH to me indicates better efficiency.Grant

How much torque you can get thru a transmission is usually decided by how quickly the clutch pulls the engine down, not by how much power the engine makes. Here's a link to my page that mines RWD dragstrip data to roughly calculate torque applied to the transmission's input shaft over the course...

Don't forget clutch engagement control devices to reduce impact on the gears, which effectively increases the amount of power you can get thru a given gearset before shucking teeth. Here's a page with a list of devices that can be found on the web... https://grannys.tripod.com/clutchcontrol.html...

Check out this thread in the Drag Race section... https://www.dsmtuners.com/threads/hitmaster-system-clutch-hit-controller-feedback.535576/With a clutch hit controller controlling clutch engagement during launch, you will be able to launch with as much rpm as you need to make power, and then...

I know a lot of import drag racers wish they had a race style "adjustable" clutch available that would fit inside their bellhousing.The domestic V8 guys have those clutches available, but there is a growing trend of very competitive V8 racers setting those race style adjustable clutches up to...

Clutch Delay Valve and Clutch Hit Controller are two different things. CDV controls fluid return flow rate from the moment you pull your foot off the pedal. CHC controls initial fluid return flow volume with no delay. CDV takes a while to get to the clutch's sweet spot, then passes thru that...

Basic Hitmaster system components...HitMaster 1st Stage Control Valve functions to allow instant return of a controlled/adjustable volume of clutch fluid as soon as the clutch pedal is released. It's adjustment knob controls the intensity of the clutch's 1st stage "hit". Rotate the valve's...

If you want an efficient 60' with an automatic, most of the magic is in the converter. If you want an efficient 60' with a manual, most of the magic is in what the clutch is doing. In both cases it's not so much about the converter/clutch itself, more about what the converter/clutch allows the...

Racepak logger with a pressure sensor on the throwout bearing bleed hose.If you are logging a Magnus release curve, the yellow trace that ends at the 4sec mark is probably the best compromise. Not likely to break anything with that curve shape, but notice how long it takes to reach a...

Ideally you want clutch psi to drop instantly to your "sweet spot" of partial engagement, then stay in the sweet spot for around a second or less. That dwell time in the sweet spot gives the car some time to gain speed before the clutch locks up. If the clutch locks up too quick, you get either...

The Hitmaster does what you need- instant release to an adjustable pre-set 1st stage of partial clutch engagement, then the rest of the clutch clamp pressure comes in on a timer around a second later to limit slipping. Amount of partial engagement is knob adjustable with plenty of resolution for...

Install one of my clutch hit controllers and you can leave from 7500+ without breaking parts. Bumping launch from 5500 to 7800 will more than double the amount of "inertia boost" available to get the car moving, without suffering the negative effects of increased flywheel weight.Here's a...
