installed a dynoport ypipe, pipe and lightweight can

[fredw]

had a buddy, that hit a tree, with his etec, and bent the pipe, rather than buying another stock one, he went and bought dyno ports full etec package that claims 8hp over stock

so he did the mod and was planning to add clutch weights, but never had any at the time, so we left as stock till he gets his kit

he was running on clicker 1 with stock setup and ran a perfect 8000rpm

now with the dyno port kit, he is still running 8000 with stock setup??

he feels a bit stronger in the midrange, but no difference up top...

not sure what to say about this, usally dynoport is spot on on its hp increases

spot on with their horsepower increases?, at 6500 they had a 4 hp increase, and at 7200 they had a 4 hp increase, kinda pullin that out of my azz but seems like they can support the facts on marginal sort of gains for your sled, but a large gain for their bank account. hard to produce a solid 8hp from a exhaust system. imo Stock set up is tuned and tested. hard to come up with anything more then noise and weight loss.

well i can tell you that on my etec, i added just the ypipe from slp, and now after 300 miles i have added 6.9 grams to stock setup and running clicker 3, so something surly changed for myself

anyone else seen these same results

Does the computer automatically adjust for the pipe ? maybe it's way rich.

Its part of the break in process. the sled gradually gets stronger as the break in wears on. Brew did the same thing with pin weight and no change in the exhaust. you may have small gains from the y pipe.

I had to add weight to my stock set up as well. I'm pretty sure I'm past my break in... 400 miles.

i should of mentioned that the buddy that bought the dyno port stuff has 600 miles on his sled, so yes its broke in, just has never added any extra pin weight from day one, and still runs 8000rpm, just like it does with dyno port

add weight you might be suprised

this is true, i have a different setup but the principal is the same, i rode it and it was at 8100, put in a 6mm set screw rode it again its still at 8100, now i put in a 12mm set screw and it finally is starting to notice the pin weight i put in, it should be close with that in my setup.

what's the performance impact of more pin weight? i'm a clutch mod newbie but am waiting for a full DP exhaust for my '11 X Etec 154 (700 kms so far stock setup)... i'm guessing clutch mods will be my next performance project so any info for a rookie would be appreciated...

i've heard modding the stock setup doesn't necessarily mean improvements just customized performance ie. do the ramps/springs provide different traction/acceleration/braking characteristics at different rpm ranges? at the expense of something else?

appreciate any insights...

Clutching is one of the best improvements you can do to a sled. Someone told you wrong there. Its the best money spent on a sled. Talk to DJ or winterbrew about it. They are both working on kits now. In my opinion your wasting money on pipe and can thats not proven. Its really hard to beat the stock pipe.

my stock pipe is toast and the DP setup is 15+ lbs lighter and cheaper than BRP stock pipe so as long as it doesn't lose any power, i'm happy. appreciate the insights though.

my impression of stock etec clutching was based on billy howards posts (dootalk) on the stock setup and his modded setups for drag or 1/8 mile racing... according to him apparently the stock 2011 clutching is actually pretty good... any other clutch guru's outhere care to comment on 2011 Summit X stock clutching and/or the improvements that are possible?
