Just curious what others feel is the best 19T combo they have found. Is it D5 or D6 based...Ti, KR, or Pt based? Also, for those that can run any 19T...what combo do you use?

Is it a D5 or D6 with standup, laydown or P-94? Is it a Ti with a KR endbell? Pt with KR endbell? Or is it a hybrid?

Just wondering is all...so far I've found the KR can and endbell with a standard size comm (Pt arm) to give very good results, both on the track and dyno.

D5 can and endbell, torque arm, orion springs and P-94 brushes. I dont know of anything faster than that.

I've been using a d6 can and endbell with p-94 brushes @ 36 deg.

I don't necessarily know if that is the best combo and I would be really curious to see how the response to this thread turns out.

Whats a "torque arm"?

Reedy Ti can with standup brushes. You can over gear them all over the place and it is still fast.

Jamie..have you tried the Reedy Quad mag (Kr) can?

The combo I stated above is what I ran at the Soo and it was fast and strong.

PUTNAM D-5, X-94 brushes, Purple springs, 24 degrees.

Bret, what type and size of track are you running 24 degree motors on? At the tracks I've been going to everybody runs at 36 deg. Had a few try at 24 but we always end up running at 36 to be fast. I would say the track size is about 120 - 130 ft. Just curious to know where the lower timing works best.

Anybody else have any motor combo's that they have found to work well?

Hey guys try a ARRCOR Epic motor with Orion of good 4383 brushes. try a silver on the pos and a red on the neg. Orion springs. max the motor out to 36 degrees. if you need a little torque back the timing down a bit. This is the motor setup I ran at the NORCCA Nats it was the fastest car out there in 19t

Hey RC,
If your track has wide sweeping turns, the 125' runline will like a 2.34 rollout @ 24 degrees if your chassis is right. I haven't been to a track that I couldn't hold a 19 wide open. If you need to lift, you may need to drop the rollout a bit. Actually if your stock guys are not lifting, you should be able to get your chassis good enough to go wide open in 19 also.
At the ROAR Nats, Arnie Fie had me covered (He was at 24 degrees too) but otherwise, my Putnam/TQ power @ 24 degrees was the fastest :thumbsup:.

Later, Bret

Oh yea, my local track is a 125' runline and I spent LOTS of time testing 24 and 36 degrees, 24 IS faster.

Later, Bret

Yup...Arnie was the only driver at the ROAR Carpet Nats that I convinced to run at 24 degrees, and he TQ'd and won...
If you use a Fantom Dyno, you can be fooled into thinking 36 degrees makes more power, so be careful...

Got a race coming up next weekend . I've got a few Putnam arms that have always been good. So I'll build up a motor at 24 deg. and give it shot.
What kind of numbers are you seeing on a Turbo Dyno to qualify as a good motor? If you could provide the steps either Amp or Torq that you use, that would be helpful.

Thanks
RC

I can only get away with running 24 degrees when using P-94 size brushes. Anyone has success with standups???

If your running arcor motors with stanup brushes 36 is the only way to go,.like Ritchie said 36 if you need a little more tourqe back it down to 32-34 also do this if you need it to finish a little better back it down a touch 32-34

I dunno.. I have run 59 lap runs @ K/N with both 24 and 36 degrees, my fastest run to date (59 4:03.0) was @ 24 degrees, regular stand up brush. The 36 feels faster for the first 30 seconds, but the 24 is so much faster the last minute, it makes up for it. I think that I am gonna try setting the motor to about 26 and leave the gear where I had it @24 and see what that gets me. I tried pining up a tooth more @24, but that didn't work, ran flat the whole run. From what I have found, if I can get the up front speed with the motor @ 24, it is going to be faster.

Oh, and to attest to Todd's statement, if you are using a famtom dyno, the thing will lead you to believe that 36 is better. Do yourself a favor, leave the dyno at home, and let the track be the dyno. ONce you ahve your motor building skills down, the dyno is really only good for one thing, comparing one motor to another. I have yet to see any dyno ever actually tell you where to gear a motor, and have it be right.....

Nothing compares to the computer on the track.. it is the only true guage.

Yup what Mr. Putnam and Lambert said is exaclty true...Dont believe anything a Fantom dyno tells you!!! And 24 degrees is better than 36..... As Todd will say and has said..."The best dyno in the world is the track and a Stopwatch!!"

Putnam X brush or the latest batch of 4383's in that order are the brush of choice in that order.

EA

Yep! lil purple box, best dyno going.

I dont use a dyno,.but i know the fastest runs at classic 189ft bank track have all been at 36deg. w/3- 60 4:01 runs i have tried 24 up and down on the gear and it just dosent rip,. what do i know though maybe it just dosent work on our track?
Maybe its a bank track thing ,. i know the top 2 cars at sandhills at the norrca nats were at 36 also.

see ya frank p

This is why I like 19 turn. So many different config. and everyone thinks there's is the best :thumbsup:.

I LOVE IT :dude:

EA: Thanks for the endorsement...you have learned well, young grasshoppah.

I have played around with the Arcor style Epic's on my Robi dyno

What I found out was at 24 degrees the power numbers at lower amp steps 18-24 were higher. But at 36 degrees the power numbers were better at higher amp steps 24 +.

I could see on a super long track where amp draw would be less where 24 degrees might work out better.
But banked amp hog type tracks I still think like Frank said that 36 deg would be faster.

The only thing faster than 36 degrees at classic is 42 degrees!!!!

Exactly. The first order of business in any motor tuning is to figure out what the average amp draw is for your particular car, driver and track combination. For the majority of the flat tracks, the average amp draw is in the 22-26 amp range. Increasing the timing moves the power band up to higher amp loads. So if your average amp draw is higher, (such as a banked track, loop carpeting, etc, utilize higher timing.:thumbsup:

Hope this helps...

is there a rule of thumb on the number of teeth speed between 24 and 36 deg. ?
or do you have another logical formula ?

TJ Towneabout 4 points on the rollout.
1.20 @ 36, 1.60 @ 24. Roughly a good place to start.

The only thing faster than 36 degrees at classic is 42 degrees!!!!
Actually 45 degrees, come on now Dusty get it right !!
Get out the tape for the endbell.

No need for endbell tape..... just use a drill, a 4-40 tap, and some cap head 4-40 screws.... and make your own holes in the ring..... :)

Or just go to around 50 degrees... where the endbell recatches after 36..... :)

If anyone else reading this thread is like me and finds stock too slow, mod too expensive and 19T too darn confusing, try brushless.
