I know you own Brood but it has never worked that way for me in 20 years.

Eddie,can this be seen on a TD-45? I don't mean to dispute you but I don't think the dyno will tell this story?

Ask Todd Putnam, Ask Jim Deiter, Ask Mike Reedy, Ask Eric Anderson.....you don't need to believe me....(search hobby talk, you find Todd making the statement)....even Big Jim made the statement on his forum.

As for the dyno, dunno....I rarely use them at races(I usually don't even bring it).....the track lets me know if its fast.....we use the dyno for production stuff, but I never build production stuff really, and usually then its modified stuff.

In the end, all dyno's, even the TD45 can be tricked....

So what effect does a brush with and without serrations have on RPMs and torque?

I have also notice this on my TurboDyno... The lighter spring give more torq and less RPM at a given AMP draw... But maybe we can't just look at the same AMP number when we change spring tension, because on the track the car with light spring will certainly draw less AMP.... If we can know the new AMP the lighter spring will need on the track and compare the TD45 number with the higher AMP number with heavy spring, maybe we will see better RPM then.... It's just a supposition, I'm not an expert

hey eddie o

just a quick question, im sure its been asked a thousand times so im sorry for asking again haha

but, what are your reccomendations for spring/brush combo's in monster stocks and also epic ROAR stocks???

at the moment most of my monsters have red pos, green neg and trinity 4499 'e' brushes, one of the motors has the same set-up but putnam green on both sides. as for my roar stocks, they have red/green set up also i think one has 4499s or 767s, and the other DID have narrowed putnam green/blue combo but now has team atlas sprint silver brushes both sides- i've yet to run it with these brushes though

if you could help me out that would be greatly appreciated, if you could find the time or be bothered to tell me what gains i will get out of this set-up or your reccommended that would be even better again

thank you very much

cheers,
robbie

I just dynoed my monster stock and at 7.2 volts it pulles about 29,000 RPMs. Is that good or is that really low. I heard it should pull about 40,000 RPMs at 7.2 volts.

For what purpose? P2K2 and CO27 have a lot of torque but not sure if that is what you are looking for.

P2K - most torque with low RPM's
P2K2 - Mix of Torque and RPM
Monster - Less Torque than a P2K2 but lot more RPM
CO27 - Torque of a P2K2 with about the same if not more RPM

We have all the above in stock at the address below... If we dont offer a tuning preference for what you need e-mail us and we will work with you..

Best of luck with your motor venture.

thanks

I currently have a couple of monsters and one P2K2.
Been only using the monsters, I'll have to rebuild the P2k2 and see how it works.

any suggestions on brushes/spring combo for alot of pull out of a corner.

thanks.
