Questions

[mikejhs82]

BMS guys:)

Justa few questions about your car.

What is the advantage,in your opinion ,to the gear diff ?

How do you prevent dirt and rocks ,stuff like that, from getting in to your beltdrive?

Why do you like the BMS car versus the CW or the Terminator based cars.?

What prompted you guys to build the BMS in the beginning?

By the way I own one of your cars and hope to be racing it this summer.It is the 2nd generation i think..lol I am not sure of the History of these cars.

Thanks Mike Warner

Mike,
Here are my thoughts/opinions related to your questions.

The gear diff is smoother than the ball diffs and only needs to be rebuilt once every year or two. You don't have to worry about melting your diff on a high bite track, like you so with a ball diff.

The beltdrive seems to be fine on all the tracks we race on. There is no protection from rocks or dirt, but it hasn't been a problem.

As far as my favorite features of the BMS car. I like the gear diff the best. My 2nd favorite feature is the infinitely adjustable rear toe (comes stock with the car). This is a great tuning tool. My 3rd favorite is where the motor is mounted compared to CW or Terminator cars (BMS is more forward). With the motor forward, you rarely have a problem getting the car to turn in aggressively, and I like that. There are others, like racing for a local company with a more personal response when you have problems.

As far as history, someone else will have to comment. I know Pete and Randy bought the company from the original owner(s) who I think were headquartered out west somewhere.

I've only been driving a BMS car for the past year or so, but my results have significantly improved over my terminator.

I'm sure some more seasoned BMS guys can add to this.

With that said, I'm glad to hear you own a BMS car. I'll have to get a picture of you sometime at the track and add it to the drivers section on the website. If you ever need any help, feel free to stop by the red BMS trailer. Mike, Pete, and Chris can answer any questions you have and even help get your car setup with race proven baseline setups.

mike i'm glad to here you have a BMS car. andy's post above mentioned many of the BMS advantages. one he didn't mention is our car has more rear camber gain than any other car on the market. the open belt drive system works well. as far as rocks and things getting in, the only place i've seen our cars have a big issue was at jrc before the new clay was put down. and even then all you had to do was make a thin lexan cover for the transmission. don't know if you will be running a sprint or latemodel/edm, but make sure to stop by the trailer and we will look over the car and give you a good base setup to start with. :thumbsup:

Thanks guys..

Although I cant race every week..I do look forward to running the car this summer as often as I am able to..

Gionni Bacoreli (not sure if that is spelled correct) was the origanal designer of the car. He was from california then his work moved him to texas. His full time job was to demanding and he sold the company to Randy, Pete and Chris. They have put alot of time in developing the car better than it ever was

i currently run a BMS sidewinder whole heartedly.
i love this car and as long as BMS is around i dont think i will ever go with anything else. the guys from bms will take your questions at just about anytime (they usually do for me anyway)
as far as the belt drive. like stated earlier it has many advantages over the ball diff. and rebuild is a snap. no tiny ball bearings to lose or get aggrevated over cause they wont seat correctly.
, just clean the old fluid out, (maybe change the bearing/bushing if its really old and worn) and put some new fluid in, change the gasket if needed and your done. put the 4 screws back in clamp er' down.
and with the rock issue. i only had it happen once but it was my fault. the car wasnt adjusted right (mechanic error) and i was all over the track, got into the loose stones at the top of the turn and picked one up. but not much was done to the car. got a small groove in the belt but it didnt hurt performance since the belt has that string webbing in it to keep it from failing prematurely.

hope this helps in your quest for answers. running a bms car might take a lil getting used to (the belt drive system's gear ratio was a big one for me) but you cant ask for a better performing/ handling car in my oppinon
(even though my opinon rarely counts,lol)

good luck and have fun,
Jared

[mikejhs82]

Thanks Jared..Look forward to racing with you this summer..



Mike

[jaredmausteller]

definitely.

[jaredmausteller]

just thought of this.......

since the bms guys now know i ONLY run BMS. maybe i can get my picture taken in front of that sweet red trailer.lol

j/k guys i wouldnt want to hurt your rep after someone watches me run,lol.

still......

THANKS FOR AN AWESOME CAR!!!!!!
keep up the good work.
see everyone after the freeze.

[rc_truck_racer]

No problem Jared. I would be happy to get your picture and post it on the website. I'll be there this weekend, and a few more weeks before the Freeze.

Anyone who drives BMS will eventually be posted on the website. You are a part of the BMS team of drivers, and we will help with setup or otherwise in any way we can.

Just stop by the red trailer and say hello. I'll try to have the camera with each week.

lol thanks andy.
but maybe ill hold off on that pic.
like i said im not the greatest driver. nor the worst.
but id hate to even think of tarnishing the bms name....
sounds funny but its a serious thought.
you guys work to hard for the high and mighty name.
ill hit you up one of these days.



p.s. i wont be there till the freeze or just after.

Have there been many guys race the BMS on a more loose track/buggy tire type surface? Being in the market for an Electric Sprinter to run in our area. Any input on the BMS on this surface would be great.

Jeff

[Jason Smith]

I have had a lot of succes with my BMS cars on loose tracks though the years. One of the few changes that normally need to be made are, longer shocks......56 shafts and bodies in the front, and .71 shafts and bodies in the rear. 7x7 top wing, softer springs, more toe and lighter diff oil's just to name a few.

If you get a chance to get more info on track size, and tire types, I should be able to give you a fairly detailed setup based on this info to get you to a close starting point.

Hope this helps

[sheriffM1]

The original BMS design was for loose tracks.It performed very well winning many many races.

[JW8]

Thanks for the info. The tracks we run on are mostly 150' to 200' centerline tracks. CW Outlaws, Hyperdrives and Harper Wire cage cars are the majority of the sprinters. We too have to run the B4 Front shocks all around the car, 7X7 Wings, ect. Tire of choice is usually Proline 3 Rib type fronts and Proline Inside Jobs.

Droop on loose tracks is very important. Do you run a more vertical front shock tower on a loose track car? I saw the nitro car on the website....there is an electric sprinter correct?

Thanks for any info.

Jeff

[Jason Smith]

There is a electric car that is currently in development/testing stages, that has shown some very promising results, but as far as I know the car has not been released yet. You are correct in needing a lot of droop. Very important. On loose tracks I actually always ran more layed over shock positions in the front and rear than normal.

I generally ran around a 6lb spring 50 wt oil, and #2 pistons. Front shocks mounted around a 25 degree angle, and rears at about 45 degrees, along with very light diff oil (35 wt shock oil) This made the car rotate through the middle of the corner quite well.

I hope you get a chance to try the car out. Maybe someone can chime in on whether the electric BMS is close to a release? Do they run nitro at sprint's at your local track? Or do you just prefer electric?

[JAC9]

I ran the original prototype electric car as an edm in 2008 for the Pa Nitro Tour and some weekly racing at Newville with the nitro cars with some good results, I then switched it to a sprint car for the 2008 Sprint car nationals at Bumps and jumps and also had good results, I know Bryan Boyd built a Mod sprint car a couple of months ago and has had some very good results as well.

Basically the electric conversion is just a new right side tranny plate and thats it. The only issue is to run it as a sprint car you need to run a saddle pack because the motor is so far forward in the car because of the belt drive. When I ran the car as a sprinter I ran a standard pack however I had to move the rack forward and get creative with mounting the battery on its side.

[mikeschellracing]

the bms electric prototype cars as of now are basically our nitro cars with some minor changes made to mount your battery, electric motor, and speed control. i'm going to be with pete tommorrow to work on the electric car developement. bms would not want to release a less than stellar electric car. therefore i'm sure it will be atleast a few month's before anything is released. your interest in bms electric cars will definatly spark our interest in developing them.:thumbsup:

[mikeschellracing]

jeff did do very well when running the electric bms prototypes. so did bryan for that matter. thank for your help and input.

[JW8]

Well we run more Nitro sprint and actually I enjoy that class a bunch. I have a Harper Chassis nitro sprinter but was thinking as electric has become more popular in the NSCS type tracks in OK,TX and here in KS about trying one. I know on our nitro sprints the more vertical tower works well. I am thinking about getting something new and your cars look killer.

Info like this helps too!

ps. do you run flat panel sides for bodies on the sprint cars?

[mikeschellracing]

the side panels on the sprint cars are vacuim formed. they are not completly flat. i know most of the guys run a removable rollcage[which can be removed by simply pulling a fewe body clips]. some of the guys make there own side panel out of flat lexan.

[jaredmausteller]

i for one make my own side panels, top wing, roll cage, and nerf bars.
the only thing i buy to complete my body is a mcallister hood and tailtank.

i also know some guys that make killer edm bodies.

[RCRacer]

As one of the first half dozen owners of a BMS Sprint car I remember the "developement" time and yes I would say that the BMS was the first "new" car that had something majorly different from what was out there, that being the gear diff..

Actually a couple of us BMS drivers were the reason that Gianni developed the EDM/Latemodel chassy.

The Diff is consistent, the car is stable, it can be tweeked and tuned like no other car I have ever owned and or messed with and it was the first car to have the adjustable wing that you see most offer now.. I still have some of the prototype low rise wing mounts somewhere in my box of stuff.

Race on..
