m7 only pulls 74-7600 rpm

[barbender]

my 06 m7 162 will only pull 74-7600 rpm i thougt thell should pull 8200 I put 74.5g weights over the stock 74g but it seemed to woke good for a year or so but dosn't seem to want to pull now. I have d&d y pipe v-force reeds and Mbrp can. Does the sound like clutching or something else.

if it used to work fine, check a spring, may be weak, if the clutches aren't clean, belt, rollers, who knows . and it should only pull 7900 to be in the curve.

 

[mtn mike on boost]

you must ride a low elev.
stock should be like 70gr.
my turbo only pulls 77gr.
w/ your mods , id think your max power would be at like 7,900

seems like alot of weight to me also, low elevations???

 

[Elkhorn]

what elevation are you at? My non turboed m7 pulls 77 grams up to 5500 feet or so, stock bore.

Yeah, bone stock M7 with gold spring, running 75g. AC weights here, 0-4500', 7800-7850 all day, all snow.
