BingoThank you for the first hand info unfortunately I ride lower elevation 50% of the time (2200'-3500') and don't want to have to mix fuel for the twins. If I have to mix fuel and spend 3k us for the outlaw stage 2 kit I might as well buy an aftermarket turbo kit for roughly the same coin.
Error 404: does not computeYou have understand they advertise 7hp, which isn’t very much. A lot of guys wouldnt notice a 7hp gain on a 165hp sled. It’s only .5% increase in power. Not to mention if your clutching isn’t 100% tuned right, the little extra hp bump you do get isn’t getting to the track.
Website says 90mm pistons are used. Do you know who's 90mm pistons?Hmmm.. I never ran race/av with the SLP head. 93 Shell only. Never had det once ,even at low elevation. The engine Duane at Powderfreaks is building me is a ported 940 with twins at 12.8 to 1 compression ratio. It did dyno runs at 202 HP on his dyno that clocks stock 850s pulling 171 -173HP. I rode it around his property last weekend. It rips so hard out of the hole. Still doing some finishing touches on the tune and clutching. Its pulling 74 g TRS weights with Tonys clutching. There is no doubt tuning (for Duane) was no easy task. He was having some hair pulling days. He figured it out. Sorry for derailing your thread got a little excited about the new build.
You probably like the twins better because they didn't run as bad as all your turbos ran ? Nobody is whining, just stating the gains, if any, aren't worth the hassle and money.I've had several turbos, 800 turbos (pro and axys) and axys 850 turbos. I like the SLP twins better
if youre not at 8000 ft+ this is a better setup than a turbo in my opinion
and if you feel the need to mix gas (not necessary over 5000 ft) you can add a couple oz of lucas octance booster per tank
or a splash of av gas or vp 110, its not a big deal whiners
Yeah I have triples on my boost ?Chadly!! Have you personally owned a sled with twin or triple pipes ?? And ridin it in the snow not on the keyboard?
Actually a 4% increase, not sure how you get .5%. To get 4% from combustion chamber shape alone is asking a lot, unless squish is tightened and compression is raised. 165 x 1.04 = 171.6hp.You have understand they advertise 7hp, which isn’t very much.
