How much HP?

[mymastifftucker]

I have a 07 450ER, currently running a full DMC Alien exhaust, K+N filter with outerwear and no lid, 05 CRF needle and a 175 main jet, also using HP4 synthetic oil. These are supposed to be around 38 HP stock, any idea where it is now? I dont know of a dyno around me. Also any one else using the DMC Alien exhaust? I bought the whole system for around $300 brand new and the fit and finish seems to be great. Its not as loud as my HMF was either. Thanks!!

With stock cam.... maybe 43 hp....

I would guess around 42 or so, though it is hard to give an accurate measure on that type of question.

Whatever power u are making now, I recommend going to the HP4M oil, much better oil. Also look into the HP Tranny oil.
For a bump in power, grab a hotcams S2 or 05crf, before you get anything else.:D
