09 800 turbo ?'s

[edgey]

I bought a 09 m8 turbo with a cutler stage 2 kit what rpm should this kit be running the old owner told me 7500 which sounded low to me what are you guys running for rpm. Also if you guys don't mind sharing your clutch setups with me that would be great this sled has a yellow white primary 80g cat weights light tips stock orange sec and straight 36 helix I know some of you are running a 36/40 something helix.

Are you sure its a Cutler stage 2? The stage two comes with full CPC clutching including Cutlers torsional secondary clutch conversion. If you are running the clutching you say then I am thinking it is a stage 1 kit and you got lied to. Post some pics of the kit and I can identify better.

He got lied to FOR SURE The dude he bought that thing from is kinda sketchy.

You can take or leave just about any of Cutler's extras when you buy the kit, just like on my 11... I don't have the cold air. He took $500 off the price for not taking that.

As to the kit, it's a stage II, no cold air, no clutching. It was a 2009 Zollinger's hillclimb sled, and it had a stock secondary & cat light tip weights. I think we dropped weight when I brought it to CO & brought it down to 80, which is what it runs now.

Zollingers told me to run 7500... so that's where we ran it. Since then though, I've heard some people say I should be higher... but never bothered as the current set up allowed us to push it to higher boost without over- revving.

8050 rpm is where i am running my stage 2.

Mine liked it from 8050-8150, still pulls hard around 7900 and all the way to 8250 but seemed better in the 8100 range, best bet, call cutler and give him all the info, then decide.

 

[RACINSTATION]

Yep. I liked the 09 from 7950 to 8050 for RPM.

You are gonna have a FUN year!

 

[backcountryislife]

Wow, way higher than I thought. I was told to run stock rpm by those guys.

well... guess there's a decent amount more in that thing then!!!

I also think that it would benefit from a multi angle helix, but it was just so consistent that we just didn't mess with it.


Just out of curiousity, what are you guys running on the 10-11 for rpm then?

 

[WyoBoy1000]

Stock rpm on a 09 is at least 7800 isn't it.
I think on the '10-11 they run around 8250

 

[edgey]

Yea the guy I bought it from was a jerk. So what helix do u guys like? Or maybe I'll give cutler a call, and stock rpm was 7400-7600 on the 07-09 with the stock pipe.

That's what I thought. I've always told people to run 7450 on the 8 as every stock dyno curve I've ever seen looked best right there. I told them we'd likely run 10ish daily, then bump it to 13-14 here & there, maybe that's why they told me to run it lower? Seems odd that Zollingers of all people would tell me to be too low.... they're not exactly in the biz of giving up horsepower


This is probably all kinda pointless, I doubt that thing will even run. I dropped a few bolts down in the case last month, then threw some pistons in there that some other dude pulled off at about 8k... Don't waste your time

Stock rpm on an 09 m8 is not 7400-7600 rpm.

 

[edgey]

Just walked to the shed and lifted the hood and the chart says 7600-7800 peak operating rpm but I know there was a few guys saying to run more towards the 7600 because they dropped off quick the higher u go with the stock pipe.
I'm glad we solved that now how about turbo clutching any tips???

 

[WyoBoy1000]

The difference in mine from 7800 to 8050 was noticeable, I like the 8000-8100 range the best. I saw the most gains with MDS weights.

 

[mynewuseddoo]

I am swapping out my 09 stock m8 pipe for a 2011 stock m8 pipe and a speedwurx turbo y-pipe as well. This pipe likes the higher rpm so I am hoping to gain and extra 30 mph on the top end in a climb but if I get another 5 mph I'll be happy I'll post my results and how the system was affected after I test the new pipe setup this winter. After that I might give the MDS weights a go as well. I love my CPC turbo mags but if MDS has a money back guarantee, what is there to loose, right! I'm also thinking about getting my hands on push's new intake system (tbbt) and incorporating it into my CPC turbo kit. My Frankenstein project, muahahah!!!

 

[Mod800R]

subscribed! was thinking of altering my setup as well...09 with a twisted race gas extreme kit...am running 7600 to 7800....seems to pull hard from 7500 up....t talked with shain about this and he is telling me they pull from 7500 to 8000....

- mds weights (running D&D turbo weights now)|
- twisted cold air intake (stock intake)
- stock 800 ho pipe and speedwerx y pipe (stock 09 pipe setup)
- single stacked boyssen turbo reeds ( have m 1000 reeds with TDR reeds over them)
- timing key

think these changes would be worth the coin? i almost bought a speedwerx turbo pipe till i called shain and he said the stock pipe has best bottom end...the ho pipe is more of a mid-top end pipe...

 

[mynewuseddoo]

The speedwerx turbo pipe looks a lot like the 2010-2011 stock M8 pipe also. I might try the Boondocker electronic timing key as well. From what I understand it raises the timing on the bottom end for more snap and removes timing on the top end to allow for lower octane at higher boost. I hope I got the raising and removing timing thing in the correct order. The 09's are torquier on the bottom than the 10's and 11's from what I understand also.

I will go back and forth between the stock 09 and 2011 pipes with the Speedwerx Y-pipe and see what I like best. If you are right about 09 pipe being better on bottom(trees) and the 2011 pipe being better on the top end(climbing) then maybe it could be a quick tuning option depending on the group I ride with and the terrain we are going to be riding on a given day. Time will tell I guess.

Let it snow already!

 

[WyoBoy1000]

Mine has the 2871 on it so maybe it reacts a little different, Twisted told me 79-8150, I have cranked the boost and hit 8400 and it still pulls hard but I'm sure If I threw more weight at it with that kind of boost it would really pull in the 8100rpm range.


The '10 is snappier than the 09 if you leave the '10 head on it. The bd timing module doesn't add timing off bottom it only pulls timing up to 3* on top. I would think you could throw a '10 head on the 09 and run the timing module and pretty much maintain octane with better bottom end. I also think cutler may have a port/head design that would work well also.

The '10 motor is ported different, different compression, and lightweight crank so it needs a more precise pipe, I have a feeling the pipe will not benefit on a 09. I think if I where to try a pipe I would go with OVS its meant to have a smoother torque pull all the way up. The SW pipes seemed finicky.

09 TM8 clutching

I was running a boondocker turbo pipe, TDR reeds, 80 gram weights in the primary, stock silver spring in primary, with a adjustable spring rate BDX helix at 36P/44 with rock rollers and a orange and white spring and it would pull 8150 RPM at WOT.

I'll be curious how you like the pipe. I have tried both on my morph 08/09 M8 and I give the nod to the early pipe. The 11 pipe was really lazy on the bottom..... mid and top were killer, but I don't think any more pull than the 08 pipe with heavy weights.

PS: if you get a kind of rev limit sounding phenom... throw more weight at it. I had my Cutlers topped out at 80 and it needed the DDs topped at about 83 turning about 8400 to work. Good luck and Sorry to hijack!

Back on topic:
My early pipe likes around 8000 rpm at 87 grams. It can be clutched to pull at 7600 and work OK, but really walks and talks at 8000.

Hope this helps

 

[mynewuseddoo]

Thanks Tony. My 80-90 gram Cutler weights are loaded at 87 grams also and pulling 8050 rpm. If I need more weight I only have the tips left to load, I don't want to do that so I will end up trying a set of Merlins Magic MDS weights or the 85-95 gram Cutlers so I can keep the tips light. I am very interested with the MDS though so probably those bad boys.

When it comes down to it, I am getting a new PC M800 next year with another Stage 2 Cutler turbo for it. I am just playing with my 09 this season to see what I can get out of the old girl at the same boost pressure I was running with the stock setup so I appreciate the info. Then she's gonna be the backup/spare......just incase.

What elevation do you ride at Tony? And what boost pressure are you running at? I'm running at 9-10psi right now but I am going to creep my way up to 12-14 this season.

Thanks
