ah yes, struggle bus, on struggle street.

[@fatbubba2097]

This definitely gives me more confidence in building a stick shift drag car. Keep the informative videos coming!

[@shadetreemetalworks]

I've been looking at a clutch tamer for my manual 5.0 foxbody (also on drag radials). The kit is only $219, seems like a pretty wild upgrade for the price. edit: ordered it, can't wait to try it out

[@laurean5998]

This is such an elegant solution to lessen the impact of the temperature/ viscosity changes and the speed coming off the pedal compared to the bang shift billy, I would like to see a side by side test

[@Calvin-Nelson]

Yeah. It would certainly be an interesting test.

[@c-man5679]

I read the "destruction's" whenever they are provided.... that way I know what I want to change and what to leave the same as the "professionals".

[@ericbengtson3490]

Holy shit! What a game changer. Thanks Calvin.

Interesting, will dig more out about this system, thanks for sharing

[@mattmorrison6958]

Wild how relevant all of your videos have been (from turbo manifolds/headers to the clutch tamer) and loving every one

[@J-Whit]

Great video. Showing the release as changes are made is awesome. Look forward to seeing the track results!

[@henzig8774]

What a neat solution. Cool stuff, thanks for the knowledge.

[@herbiederby3394]

Cool system indeed.....as Jim Carey would say ....I LIKE IT Alot....LOL...🙂👍🙏

Great explanation.. Wish I had this in the 90s

[@bobroberts2371]

2000's ish Camaro and possibly other cars has a fixed clutch engagement restriction / check valve as an anti abuse control.

[@Smokey72013]

Nice piece that clutch tamer is. Good job on explaining it all. Love the old cars and smart planning speedshop work instead of pounding boost into a engine to go faster yall fix em up right cut weight set up suspension and all. Nice work.

[@Calvin-Nelson]

Yep. At some point it will get a bit more power, but not until I figure out how to make it work at the current power level. Lol

[@Low760]

Awesome. I knew about slippers but not the tamer!

[@buiItnotbought]

Stick shift for life. I had the shock style clutch tamer before. Now im using a line lock and a portioning valve controlled by the ecu. Great info in this video!

[@steveyoutube1709]

Excellent product comparison

[@brucehowie4794]

Awesome video, great information, well done. I recently ordered the Muscle car version of the Clutch Tamer.

[@rickybailey7123]

Dam son u turned the breath out of it and side steped it wow i cant bleave it drove back to the trailer !! The rear tires hoped off the ground lol that was 1 hell of a test to the drive train !! It looked like the person driving that car was trying to kill it like he was in a fight with the car and gave it the KO !! Hopefully this came across funny i was trying to be !! Great job keep the videos coming didnt mean any bad vibes !!!

[@Calvin-Nelson]

Yep. First time racing manual. I'll try to be more gentle next time! Lol

[@rickybailey7123]

Best sounding 2 step ever hell yea brother 💯 💪!!!

[@BigPermGarage]

I appreciate the whiteboard explanation as the accumulator part is new to me. I paid up and put a Magnus on mine which is just a line lock solenoid and a flow control valve. I struggled big time with it even on the loosest setting to the point that I removed it and inspected the clutch. I have a pressure sensor in the line now for a baseline to compare if I decide to try the Magnus again but may try something else. I would have liked to seen instructuons with it even though its fairly straight forward.

[@bvward]

Calvin, I love the methodical approach to the issue. I imagine more parameters could be factored in (clutch temp, air temp, relative humidity, color of your socks, etc.☺)...

[@Calvin-Nelson]

For sure.

[@michaelblacktree]

I was actually going to use the slipper valve & parking brake method you mentioned in the video. But now I'm not so sure about that. Looking forward to your next track day! 👍

[@mpetersen6]

Torn up gear set. One reason IMO to use a Ford 9" rear end. Disconnect the driveshaft. Pull the Axles part way out. Pull out the Pinion and Ring Gear Carrier. Fish all the debris out. Yada, yada, yada. In the heyday of the TransAm series ALL the major teams were using Ford rear ends. Not so much because of the durability so much but because they could have different gear ratios for fifferent tracks and changing them out once the lash and tooth engagement was set up (on the bench) was a lot faster. Funny story. I worked for AMC/Chrysler for over thirty years. Sometime in the 70s AMC had excess capacity in their Axle department. Ford contracted them to make ring and pinion sets for econo boxes. When the first sets came off of production to Ford specs they were setup in an inspection machine to lash and engagement specs. Howled like hell when run. Ford engineer thought they sounded pretty good. The machine next to that one had a set of AMC gears in it. Running it was a nice smooth low frequency hum. The Ford guy said, "oh thats alright we'll just put more noise insulation in". The difference. We ran all our gear sets through a lapping operation. Ford didn't. Gear teeth were cut on the exact same type of gear cutters. Gleason Hypoid type. And all Ring and Pinion sets will normally have at least one if not both gears cut with an odd number of teeth. This gives the maximum number of tooth engagements before the same two teeth mesh again. Also have

[@Greaseland]

I asked AI if Ronnie Sox could beat the Clutch tamer. It gave a detailed explanation but was Inconclusive.

[@user-pu5vd1hw4v]

Yep, burning a little clutch is an easier cheaper fix than a sudden dump of the clutch.

[@user-pu5vd1hw4v]

I would love to see any updates on the 4.2 vortex engine. I am driving a trail blazer and have access to another that has its 4th bad trans. Such as single turbo and any minor tweaks to a stock motor. If I got between 300 & 400 hp I would be extatic.

[@robertheymann5906]

I've replaced many rear diffs and transmissions until my left foot learned that softer touch. Dumping the clutch just destroys parts

[@adamlambert3892]

Good vid Calvin

[@TheSartinBrothers]

Super informative man!

[@narnarnarnarnarn]

That definitely looks like the best system of the ones you described, very nicely designed. I wonder if it would work to have the solenoid valve open at a set wheelspeed - unless you change your gearing, I think you'd want to fully engage the clutch at pretty much the same speed to keep the engine at a good RPM. Obvously that amount of time will change depending on how hard you take off, so if you're just using a timer you'd have to adjust that alongside adjusting the accumulator valve thingy. Might not work in practice but who knows, I wish I could test it!

[@fuse8052]

This is an interesting piece of equipment. Cleetus uses a slipper clutch with changable weights at adjust slip/grab.

[@Calvin-Nelson]

Yeah. I don't have to jack up the car between every run, so I like this better! Lol

[@fuse8052]

@@Calvin-Nelson Very good point

[@Thehouseofboost]

I have one of these on my Awd civic, the only thing I notice is that I have to put a half a turn of bite on my first pass when the clutch is cold, after that I turn it back and it’s fine for the rest of the day. I picked it for the same reasons you did.

[@Calvin-Nelson]

Nice! That is awesome insight. Thanks for the pro tip

[@BlaserBuilds]

👍👍👍

[@craigritchie1933]

Great video as usual. For the more basic kits, you can install an easy to adjust clutch pedal stop , then you can simply push the pedal to the floor ( stop) . When the last yellow light comes on you side step the clutch, the bleader valve regulates the apply speed thus the time it takes for the clutch to take up, this provides consistency and progressive application of the power . You won't have trouble with roll out as theres no drag on the clutch provided the clutch pedal stop is adjusted correctly.

[@Calvin-Nelson]

Yeah. Still not a fan of that solution. Just seems like I would screw it up.

[@vtwinaddicted5852]

Calvin, went to our local u pull it junk yard they must have 12-16 trail blazers with complete 4200's

[@Calvin-Nelson]

Yep. They're everywhere.

[@michaelblacktree]

Yep, it's a common engine. I'd love to stuff one into my BMW, but that would require major mods.

[@user-pu5vd1hw4v]

I think that most Trail Blazers that are out of service have fried transmissions.

[@whereisamerica7384]

Very cool. Awesome breakdown of the different systems. Also, which can keypad is that and how is it hooked into the Holley? Getting better with efi, but still learning. I really enjoy your in depth explanations. Thanks for sharing knowledge.

[@Calvin-Nelson]

It's just a basic Grayhill CAN keypad, but it is not hooked into the Holley. I have a Maxxecu that handles the VVT on the engine as well as the CAN keypad stuff.

I bet you could set that up for 2nd gear launches.

You most certainly could.

[@andymarshall4014]

Hold up. I see clutch temp do you have a video on where and how your taking that measurement? Always love the in-depth on how things work

[@Calvin-Nelson]

It's just an infrared temp sensor pointing at my clutch. It needs refinement.

[@xozindustries7451]

Very cool setup, I’m just wondering why you need the accumulator instead of just using a PWM solenoid controlled by a table in the ecu, and if the ecu controls it could you set it up in conjunction with traction control?

[@dennitone8107]

Why is my brain sore ???🤤

[@steveyoutube1709]

Sorry about all the questions… how did you get the flexible cables, are the brake lines ?

[@Calvin-Nelson]

Yeah..they're just regular AN lines that are rated for the pressure.

[@trailerparkcryptoking5213]

Gonna burn up a clutch or two in the “learning” curve...! 😂

[@Calvin-Nelson]

I doubt it. It's only slipping for like a second.

[@ramboracing3551]

Probably next weekend.

[@bertvisser6423]

Is there any fluctuation in pressure relieve with different temperatures aka oil thickness? As in,early morning low temp to last run of day where track and car are hot.I could imaging a 1000th of a sec to make a big difference in launch time

[@Calvin-Nelson]

It's entirely possible. Haven't gotten there yet.

[@hackjobhotrodshop5075]

What are you using for a clutch position sensor? Are you measuring the throw out bearing or the clutch pedal?

[@Calvin-Nelson]

It's just a low doller Motorsports linear position sensor that is rigged up on my clutch pedal.

Pretty sure I'm to dumb to understand how this works because the video didn't make any sense to me but I too read instructions usually 3x before I install anything on my car I did that for my Super Sniper 2x4 EFI and it works flawlessly.

[@jrobpat0154]

At 13:17 shouldn't the bleeder be at the top to ensure no air remains in the cylinder ?

[@Calvin-Nelson]

I can move it around when I bleed it. I just rotated it up.

[@Stevesbe]

Slicks instead of radials?

[@Calvin-Nelson]

You could do that as well.

[@daleknapke4981]

What clutch friction material design do you recommend to handle the slip and heat?

[@Calvin-Nelson]

I don't have a ton of experience with that, but for the higher horsepower stuff they say that sintered iron is the way to go because it is very stable with high temps. I think my clutch is an organic clutch
