10-66 weights...8300 should I go to 68?

[RandyS]

09 700 rmk ...40 miles on it now....I am running flatland so pulled the 10-58's the sled came with....did a check and got 8300....also noticing a bit of noise from clutch area...maybe that is normal?

on the 600, I put in 10-64's and it pulls 8000/7950 so I am happy with that....

would you try some 10-68's?

 

[milehighassassin]

What elevation are you running?

 

[RMK-King]

My 09 RMK 700 runs 8000rpm with 10-66s at 2000ft.

 

[RandyS]

I am in central Saskatchewan Canada...1575 feet.
Thanks.

Still running the stock helix?

I would go to more helix and build track speed faster and load it that way.

[suitcase]

Stock pipe you should be pulling 8100. With a pipe 8200 to 8300 (SLP)

 

[RandyS]

stock clutch...mbrp can.
I would rather not spend a bunch of money on clutch right now like new helix if possible..

 

[440dart]

my 08 700 really woke up the more miles i put on it i actually was dissapointed in it "powerwise" but i came off a turbo rx-1 around 200ish miles it started to come around i would wait put a few more mile on it.

i would also sugest trying different rpms try 84-8500rpms mine with single pipe semmed to run better with a few more rpms i wonder if our tachs are off a few cuz mine really woke up once your sled fully breaks in i bet you would be close to 84-8500rpms

 

[jaynibs]

My 08 D7 with a stock set up runs up to 8450 to 8500rpms @ 2400ft. I thought it was a bit high, but the sled is running great!!

 

[RandyS]

I thought 81 or 8200 was max rpm?

 

[RMK-King]

According to this 8000RPM is the peak power and torque,I have noticed from reading on here these 700s can vary 400RPMs from each other all set up the same. Wonder if the tacks can be off a little? Maybe some just run stronger then others.

wasnt sure if the tachs were correct or not theres quite a few on here that have had the same exsperience by bumping up the r's the sled ran alot better.just try it out and see what works for you. once the sled breaks in you will be in the 84-8500 area you will gradually feel an increase in power

 

[RandyS]

so running 84-8450 won't blow my engine?

 

[440dart]

my d7 with twins runs 8700-8800

 

[sled_guy]

With the stock ECU? If so you are WAY into the timing clip.

sled_guy

 

[440dart]

whats the timeing clip???? thats where slp told me to run them. so its pulling timeing up that high?

 

[sled_guy]

The current sleds all have over rev timing clip (retard) built in to them. It's like a rev limiter I suppose. I'm really surprised SLP said to run it that high with the stock ECU. I don't have the timing curve handy, but on the 800 above 8400 it starts pulling timing out of the motor and kills the power as revs increase.

Maybe someone has the timing curve for the 700 they could post.

sled_guy

 

[440dart]

hmmmm yes i will defintily have to call slp to find more info on this timeing clip man this thing rips compared to the single be sweet to find some more ponies

 

[skibreeze]

08 700 rmk spec is 8250 +/-300 rpm.

 

[440dart]

whats the rev limit on a 700. 8250 cant be where it starts cutting back timeing 8200 is peak power
