Title: animal engine differences
Post by: mod9 on October 31, 2010, 11:55:39 AM

The M series already has the correct crankshaft and gear box and ignition on it for the quarter midgets.
The L.O. 206 also has the correct ignition but does not have a splined crank or gear box on it.you will have to purchase and install the correct crankshaft and gear box.
 I think the regular animal has a different ignition on it and it does not have the crank or gear box either.
 I purchased the L.O. 206 and installed the crank and gear box myself, while it was apart I measured everything and found it to be right at the specifications permitted by USAC rules therefore it did not need to be machined to be competetive.I also saved quite a bit of money doing this myself.
 These motors are quite impressive quality compared to the honda motors ,Everything from the carbs to the billet flywheel they are purpose built race motors.
 As far as power difference I could not tell you but after studying the Briggs website they list the L.O. 206 as having 9:1 compression vs. the M series at 8.5:1

Can anyone confirm if the compression difference is or is not an advantage?

All the Animal engines past & present are 8.5 to 1 CR. This includes the standard Animal, LO206, LO206 Jr and the new Series M motors. If it was published at any time of 9.0 to 1 this was incorrectly stated.

so where do you get a m-series motor? i read on the briggs web site about them and i only have 1 question about he motor.does it come with a gear box? it say it comes with a splined crank but say nothing about the gear box. if they are quarter midget ready what is the price?

The M series engines are avalible from any Briggs Motorsports dealer now. The part number is 124332 8203-01. The engine does not come equipped with the gear box but it does have the correct splined crankshaft. The cost with the gear box added should be in the $700.00 range give or take a little. This cost is in stock form from Briggs and should meet the USAC 1.5 engine rules.

if i get one of the m series briggs.where can i get a gear box for it.will a honda gear box fit on it?


Title: Re: animal engine differences
Post by: BRE on November 12, 2010, 07:29:21 AM
mod9 - You can purchase gear box from any Briggs motorsports dealer. No, Honda gear box will not fit the Animal furthermore the USAC 1.5 rules require only the Briggs gear to be used. Hope this helps.

mod9,
       Why don't you just give steve baker at baker racing engines a call and have him ship you one complete.In my opinion, you will not find a nicer, more complete motor builder, at least in the midwest.  I am sure he would be more than happy to help you out.

Could you restict an Animal to run with Honda 120 or 160's? Allowing the combining of the classes?


Title: Re: animal engine differences
Post by: wesracing on November 12, 2010, 01:51:14 PM
I think that was the intention in the beginning but found that to get the 2 motors to run on an equal level it was nearly impossible. I believe that was with the restrictor plates though. It maybe a different situation if we were to run a different slide to restrict it. I do know with a different slide, they got them pretty close to run with the 120's in the rookie class. I believe the animal motor is currently allowed to run with the 120's in the rookie class.

I would hope they wouldn't try to combine the Jr classes.  The great part about having the Jr Animal is we can get our younger drivers more experience with an affordable platform.


Title: Re: animal engine differences
Post by: wesracing on November 13, 2010, 03:18:46 AM
I agree that it would not be beneficial to combine the 2 classes in the competitive classes. I have not even heard talk at any of the meetings to even attempt to combine anything other than rookies.


Title: Re: animal engine differences

There is NO talk of combining those classes.
But -
What do you think about making Jr Animal 5-9 and Sr Animal 10-16?


Title: Re: animal engine differences
Post by: mod9 on November 13, 2010, 02:26:24 PM
what do these engine builder do when they say blue printing the motor and are asking 1000.00 plus for a motor when i can buy a new one from briggs for less than 500.00?


Title: Re: animal engine differences

Eric
I think we should leave it the way it is.


Title: Re: animal engine differences
Post by: wesracing on November 13, 2010, 11:16:13 PM
mod9,
     I am not 100% sure of everything they do but I do know they deck and mill the head and block to give you the most piston pop up per USAC rulebook. This process takes a lot of the "blueprinting" out of the equation. Since they can do that machining, you no longer have to look for that crank,rod,piston, etc., that is at the limit on tolerance, to give you the most hp. Also, that $500 motor from briggs does not have a $200 gearbox and it may or may not have the splined crank that you need for the gear box.

[/quote]  I would just leave it at jr 5-8 and sr 9-16 and would like to see sr at 275lbs not 295 lbs just my 2 cents


Title: Re: animal engine differences
Post by: ezoner on November 15, 2010, 12:34:23 PM
I would suggest changing the weight to 295 lbs until there are enough for a heavy class to even things out. Or at least make things a little closer.


Title: Re: animal engine differences
Post by: BuckeyeQMDad on November 16, 2010, 12:53:58 PM
I agree Ezoner- there currently are not enough total animals to run 3 different classes- but by increasing the weight for seniors it will make it easier for the bigger/heavier kids to compete until there are enough for a Senior and heavy class.

Regarding Junior, LEAVE IT ALONE, it's good the way it is- we don't need anymore Brainiac changes like this new bs exhaust deal all because it needs to "sound better". I don't care if it sounds like a weed wacker- but I do care about the $150-$200 I'm going to have to drop to get the new exhaust. Or maybe I'll just put my Animal up for sale and be done with it. Anybody want to place a bid on the baddest Jr Animal engine in the country?

sorry last i checked sprague wasn't selling his baker jr animal ;D

I was wondering why I couldn't keep up with you guys on the track. Lets start the season over with the Jr Animal so I can get these updates. I was tired of catching the rubber coming off the back of your cars.    :)


Title: Re: animal engine differences
Post by: wesracing on November 16, 2010, 07:45:02 PM
I personally feel that USAC is giving the notice of the new exhaust rule on the animal with plenty of time. What do we have like 3-4 months to work it in the budget before the first Midwest thunder race at the end of February. If you can't budget in $150-$200 in this amount of time, then I think you are in the wrong sport. Besides, nobody has said you have to buy this exhaust. If you don't have the money, run your old one!!  As for adding more to the weight limit in sr.animal, I am running out of places to put weight in the car to get 295. Just my opinion!


Title: Re: animal engine differences
Post by: ogracing on November 17, 2010, 07:54:48 AM
lets think back here a little bit people when we were in the other sanctioning body you would of been kicked off the forum for discussing this and you would have to buy a new pipe and your old one would be illeagal with no vote


Title: Re: animal engine differences
Post by: RBurns17 on November 17, 2010, 08:07:04 AM
I agree with og about freedom of voice on this forum. My opinion about the pipe is that with any new platform you have to expect x number of changes as the platform develops and becomes more seasoned and tested. Now, if they did they several times in several years, I would probably be the first person complaining about it, but I feel confident that the continuity in parts for the more tested and seasoned platforms shows that USAC is not looking to institute unnecessary changes to the rules that will incur costs to the members.

I couldn't agree more! 

Just take the money you would have spent on valve springs and valve cover gaskets this past season if you stayed in a Honda class and buy a pipe. :)


Title: Re: animal engine differences
Post by: ezoner on November 17, 2010, 10:09:47 AM
My point on the weight is if you want to grow the class, you need to make it fair for all and if you expect to run heavy with the smaller kids, the weight should go up on a temporary basis until it makes sense to split the heavy and standard class.  If you leave it at the light weight, I will be out as will any other heavy class drivers.  It wouldnt make sense to run with a 40lb difference.

Post by: Karnes29 on November 17, 2010, 12:12:55 PM
Here is my thought on the pipe:Yes it does sound good and every parent/"handler" is going to want there kid to have it because it looks good and it sounds good,I simply wanted to know if there was a advantage running the new pipe versus the old one? If so then i wasn't going to run the animal until i got the new pipe.I don't care if it cost $100.00 or $1000.00,I was talking about getting one before this weekend NOT the midwest thunder race.


Title: Re: animal engine differences
Post by: JP3Racing on November 17, 2010, 01:49:36 PM
I honestly don't have anywhere else to put weight in my car and it still be safe.  The kids who  run senior at 9 years old are typically not big kids.  295 is already difficult enough.  You can't forget them unless you are going to change junior to include nine year olds and you'll lose some of the advanced kids from animal until they can run senior. 

As far as the pipe goes, it's always going to be about the next thing that provides an "advantage".  Innovation has driven the sport for 60 years.  I don't see that ever changing.  Someone always has the money to buy the "better" parts and manufacturers will always have influence on sanctioning bodies.  Unfortunately you must pay to keep up or get left behind.


Title: Re: animal engine differences
Post by: ezoner on November 17, 2010, 04:09:06 PM
Never mind JP  I was thinking the weight was 275....  But at 295 I think I can get there, but it will be tough.  I can get close enough to say its set-up or the driver and not the weight.

I ran the SR Animal at the fall nationals.  As the results wont tell the whole story (broke chain) the car was competitive with the others.  Never ran at that track before or with this motor and was on 2nd place bumper.  We were 355# at the scale in a 295# class.  I felt that we were at less of a disadvantage being over weight in that class than I did in the Honda classes.  The motor made me think I had a race car instead of a "go cart."
