Working on Sunday, somebody in the next week or two will be a happy camper with their new SPEEDUTV.

So we had Chads car out last night and had a @Fabhouse snd Jason from tube works look at it..

They were looking at the break linkage and determined that just adjusting the clevis they were able to adjust the pedal a little further out and this improved breaking A LOT..

Chad was hitting the floor before it was getting max pressure.

They also had some suggestions on different pads etc

They were both very impressed with the car.
Are you talking this adjusting it here?

I'm assuming they pulled the clevis further away from the master, to move the pedal closer to the driver?

***my opinion, with literally no data provided to back up any of my thoughts***

Quick observations- @RiverDave please copy this to the other thread-
First and foremost, I really like this car. There are so many elements that are well considered and engineered-very much from a racing standpoint. A few stand out, and i'll get to that. The overall conception vs execution of the car, in my opinion, are close to Robbie's intention. I see some things that may have been compromised based on building a production vehicle, but overall...really impressed.

The brakes-
***we did not pull a wheel, we did not test pressures, we did not measure caliper deflection, we did not measure master or caliper bore***
pre drive, noticed a likely small bore dual master cylinder, I would guess 5/8 but not larger than 3/4. Dual piston sliding caliper (2 piston inboard) with +/- 28mm bores. Appears same front/rear.
First drive (Lake Havasu, in a neighborhood, on asphalt)
First stop, cold brakes, 20 to stop. Lock rear brakes, not terrible, but pedal to the floor and not great....
Second stop, 20 to stop, worse.
Drag brakes at 30mph for 1/2 mile to induce some heat. 30 to stop, no lock, getting worse.
Repeat for 2 miles of this and as heat was introduced the power reduced. Likely organic compound.

Sintered pads would be my choice on this.

Pedal throw was lacking, feel was non existent. Adjusted the clevis on the pedal to master, approx. 3/8" total (after 3 tests) in order to gain pedal travel. This had a very positive effect by allowing more brake pressure at the calipers. I asked Chad to do the test drive as he has the most time with the car. He liked the first change and asked for more...after the 3rd he was able to lock brakes on asphalt and said it was a different car in the dirt.

I will finish this in a bit....kids need attention...

So Chad Nelson stopped by a friends place last night and @Fabhouse and Jason from tube works were there.. they literally adjusted the clevis on the brakes and gave him some more pedal throw and it greatly improved the brake situation.

They also suggested rubbing different pads.. those two pretty much figured out every problem in twenty minutes..
So what's the fix on the overheating. Lol

**observation only, I spent an hour with a car, mostly looking at braking issues**
It seems that the oil cooler is mounted directly in front of the radiator. It covers 60+% of the radiator surface. Likely a packaging issue. Creates a huge reduction in airflow to the radiator. ***this is not always an issue, and oil and water temps should have a pretty close delta, +/- 30deg. I think the larger issue is the windshield, with cabin airflow both coolers should work fine in concert. I would likely consider a heat exchanger rather than the finned oil cooler if i had the choice, in order to more expose the radiator and still offer balanced water/oil cooling.
I was being a smart ass actually knowing that nobody (that I'm aware of) has taken the back seat out and started looking at this.

The master cylinder is mounted pretty high vs the lines and calipers, but I wonder if adding 2lbs residual valves would help? Should increase line pressure and shorten the peddle throw?

I just assumed the cars had it but maybe they don't.

There could be? I don’t know? With the master mounted so high up, in theory you might not need it, but then again it might be worth looking at.

That's good to hear. Maybe its as simple as adding a line to the dealer prep checklist, if that is found to be the common issue.
It would make sense - i'm sure they were happy with the brakes once they finished development and put the final version in production with all the factory hardware / pads etc. Adjustable throw on the pedal "push rod" would be that one variable that needs to be checked and set, besides the reserviour being filled full with fluid and fluid bled to get all the air out of the lines. People issue, not a hardware issue

It’s never a people issue in mfg, it’s process or component.

People are rarely the issue.

So setting the throw of the pushrod coming off the brake pedal into the master cylinder - having a checklist to ensure that adjustment is set properly (by a person) isn't gonna fix it?

That's what im eluding to - somebody needs to adjust the brake to spec. That's a person doing that, and probably during dealer prep

Yep, but that isn’t a “people” problem that is a process problem. You have to tell the people to do that step or that check. Without that process step you can’t blame the people.

This isnt one person forgetting to do those things. It’s missing from the mfg operations and checks from QA/QC

If you want to point to people then it goes to whoever is running their mfg operation and build processes. You can blame them for not having the check in the process.

Take this to any auditor and they will tell you the same thing.

I said they should add adjustment of the brake pedal to the dealer prep checklist

What I ment by "people problem" - is it's not design or hardware. A person needs to adjust the fucking brakes 🤣

I'm not in manufactuering, I don't work at Speed, so i'm not taking it to an auditor lol.

So we might not need to add this once our cars come in? That's good news.

I'm not buying the minor shaft adjustment made up the difference for the bad brakes, placebo effect at best. There is no way that the adjustment was an oversight by the engineers and the other people that have questioned the brakes.

They didn't state itfixed it they just said it was better and different pad material should increase effectiveness as well

To be clear it just made things better.. the brakes could still be improved on..

Maverick R wins the overall when the scores are totaled. Sounds like there was definitely some controversy with RG if you listen till the end of the video. They are not going to use Speed cars in their videos anymore because of whatever happened.

I was messaging Chad last night, it's not necessarily RG that is the reason, it's all the Haters of RG and Speed that are part of the problem, and the drama whenever they post about the Speed.
He did a quick video comparing his Pro-R to his Speed, and he said he literally got a death threat because he said some things he didn't like about the Polaris.

People in the comments are saying RG was not happy with Chad (because of the Pro R video) and that's the reason it was pulled?

Thats the problem, People. Were those people RG, or Chad or anyone from the SXS guys?

I'm sure RG wasn't happy, but Chad has really had pretty much only good things to say about his Speed.

I don't know. For some reason Chad pulled his car from the shootout and supposedly RG said he would bring a car himself to beat the time of the top car in this shootut. Sounds like RG is definitely involved.

I was just looking on the Speed website. Can’t order or place deposit on a base model El Jefe or any other base model. Don’t think I have seen a base model car delivered yet either. What’s up with that? Go be pour somewhere else. Lol

Sounds like Robby being Robby again. His nerves have got to be pretty fried about now. He is finally seeing his dream coming to fruition, and he really has no more fuqs to give about negative comments from netizens.
It probably is past the point of expecting people to cut him slack because of his own talk, but it is pretty easy to see why it is going down like this. Guy on the video is probably taking the best route right now for himself too. Plenty of time to give a review when Robby has to target everybody. Sad actually, bringing these things to production is a huge deal. Too bad he has to tarnish it.

The guy from the video is Chad, he told me it wasn't directly Robby, but rather the drama that the car brings, from EVERYONE. Like I said, he told me literally got a death threat because he did a quick video comparing his ProR and his Speed, and someone was so pissed that he said some things he didn't like about his ProR. So it's PEOPLE that made him pull his video, RG included, but not because he told him too.

Been like that over a year since before Sand show 2022 They’re not gonna make enough profit on those base models. I don’t think it’ll be an option any longer. Things have changed in three years or for however, you want to look at it

Or say something that you like about it, and have your business and even life threatened by fucking nutballs on the internet.

Dave, I'm back out and picking up my car on the 14th, I was talking to Chad about a ride, sounded like he wants to figure out the ride to Oatman. I wouldn't mind a ride to Yucca to the Burger place.

And elsewhere, it’s just freaking nuts that these people will complain about something they have no interest in. I don’t like eating chicken, but I don’t talk about it every day for three hours.

Chad owns a real estate team out here and does this shit for fun.. he doesn't want or need the drama.

Don't blame him one bit. Not worth the time and effort.
Better to just go drive it...enjoy it.
