09 M8 Rpm

[smokin800]

What should the 09 M8 162 be tacking at. Any advice would help thank you. Ride between 6-9000 ft.

 

[Tempest]

I clutch for 8000-8100 with my Slp pipe. Stock I think they are saying 7700-7800

 

[smokin800]

I am only pulling 7500 to 7600 any recommendations

 

[Tempest]

I run a Cat Gold Primary, CPC torsion secondary/their recomended spring and helix, with 68g Cat weights, for 9000 feet.

Hey Smokin800 did you notice the drop after you put the can on or before as well?

 

[smokin800]

It has always tack that.

On the dyno sheets, the max horsepower is at 7800 rpm's. Look under the hood, near the primary clutch and there should be a little clutching chart with elevation recommendations, and what the max rpm's should be. If you are pulling a 2-3 hundred rpm's lower than 7800, then I would recommend dropping a little weigt, maybe a gram, or two.

What about changing to a different spring.

 

[Frostbite]

Yup, good idea!

Maybe an SLP spring? The stock spring is a 122/285 spring.

There are 120/310 springs and 120/340 springs

There are also 140/310 and 140/340

and of course the 160/310 and 160/340

If you would like stock like engagement try one of the 120 springs.

To gain some RPM the 310 might give you??? Maybe 75-150 RPM?

The 340 might give you 150-200? You'd have to try it to see how much you actually gain.

You can also go to a stiffer secondary spring to help eak another few RPMs out of your setup.

You can go to a slightly lower angle helix too to gain some RPM, are you running the stock 36 degree helix?

 

[smokin800]

everything is stock except the can. I am about 250 and 6'

I'd try the SLP 140/340 primary spring first. It's only about $20 and if it works (and I think it will) it will save you some money.

If you are turning 7,500-7,600 you should be awfully close to 7,700-7,800 with just this spring change.

Thanks I will try that and we will see what happens. Any other suggestions would help.

 

[smokin800]

anyone have any other suggestions.
