100 grams+12000 rpm's+big boost=?

[zebiraross]

Pulled all 3 weights and pins off the sheeve. 100 grams of weight, 12000 rpms's and 20 psi. Guess I now know the limits of the stock primary. It may not look like it but this clutch only has 300 miles on it.

 

[smv sledhead]

Ouch. Hope the crank is OK.

 

[TBird]

It's an Apex engine, so crank should be fine,
And OUCH, dangerous when all that mass comes flying in that speed, see positive on it and be glad you survived!

Thats awesome!! Makin big power

thats why I hate cast primarys... Micro belmont is your friend.

And i'd check the crank, i've seen a few boosted drag R1 yammi cranks crack,yes very rare but thats a ton of force on it. IMHO

 

[TBird]

Must be language barrier, the clutch isn't attached to the crank, so you must mean crankcase or something

Supertips i presume?

 

[2XM3]

My bad, forgot apex has reduction at pto unlike R1.

Looks like its time for one of these.

I think the RPM was the killer more so than the weight. A heavier clutch may do the same thing spinning that fast. I'm not sure what the exact reduction in RPM's are, but at 12000 on the motor, the clutch was probably close to 10000 which is way past the efficiency point.

Zeb glad you didnt get nailed by one of the weights coming off. that turned into a long day and night. thanks to Val for getting us out.

 

[Thistledoo]

Zeb is this on your new build?? I pressume it happened on a full pull?? got any pics of what got damaged?? I can pnly imagine

It was my new build. It took out my primary, secondary and that lower plastic piece.

 

[twsandrew]

Yeah, a very late evening. Zeb and I got home around 1. Thanks to Val and many others who helped

 

[Radski30]

WOW!!! That is insane. I only wonder what the supreme tool clutch will do when Zeb turns it up to 30 PSI. That is CRAZY

 

[up-high]

I think the gear reduction was to get the clutches down to 8500 or so. No wonder the primary let go!!! lucky you didn't get hit that would have felt like getting shot

 

[zebiraross]

Supertips i presume?

Yup.

Thats the plan.

I'm sure glad a weight didn't go through my leg. Scott from Diamond S said he had a similar issue and it broke his foot. And thanks a million for your help! Thanks to everyone else including Val who helped.

Ya it's off my new build. It took out my primary, secondary, and that lower plastic piece. I only found one weight, who knows where the others are, they shot off like bullets.

Glad you didn't get hurt. I know how it feels, had one grenade and send chunks through the hood 30ft in the air. Sounds like you guys had a decent ride, wish I could have went but my brother would have never made it with his kid on back. I'd like to plan a may ride.
