Finch Posted October 5, 2013 Report Share Posted October 5, 2013 Why not nitrous? Turbos seem like a lot more work and tuning issues.coming from the guy who can't tune his stock bike. Quote Link to comment Share on other sites More sharing options...
Turbo Chassis Posted October 5, 2013 Report Share Posted October 5, 2013 start off with a stock cylinder bike, stock stroke, stock everything....put a good clutch setup in it, cut tranny if your drag racing...buy plenty of spare parts...and expect to have to change parts.....once you figure out how to keep reeds, pistons, and crank seals in it....you wont ever want anything else Quote Link to comment Share on other sites More sharing options...
Stimbert Posted October 5, 2013 Report Share Posted October 5, 2013 Haters of turbos have never had one or rode one Get your popcorn The problem with buying a turbo "kit" is the fact that no matter how good the builder is and/or how simplified their kit is it is nearly impossible to get it to run perfectly pass after pass. When they're on, they're stupid fast. When they're off, others can keep up . Dan hull is a buddy of mine and he'll tell you flat out that he doesn't push the turbo kits because they're so involved. Tyson has simplified his kit to make it more user friendly but he'll tell the same thing Jordan said, invest in crank seals and reeds. Which to some is a deterrent but for 160+hp out of a stock 350 is incredible Quote Link to comment Share on other sites More sharing options...
J-Madd Posted October 6, 2013 Report Share Posted October 6, 2013 ^^^ I have never seen a turbo bike make 2 or 3 clean passes in a row. Sometimes in a whole weekend. 4 strokes included. Like QP said, when they do go, they are fast. I've never had one but always wondered what changes (or what the tuner changes) pass to pass. K&T was always looking at something on their Raptor when they would decide if it was gonna make a pass or not in the pre stage. Quote Link to comment Share on other sites More sharing options...

hughmyron Posted October 6, 2013 Report Share Posted October 6, 2013 Blow thru carb setup must be a fucking bitch to get running right. If i were to go the turbo route id go Fuel injection or do it to a four stroke. Quote Link to comment Share on other sites More sharing options...

Id expect the plumbing and mounting of the turbo to actually be easy, the difficult part is ALWAYS having to tune depending on weather. Turbo stuff is really A/F dependent.

trickedcarbine Posted October 10, 2013 Report Share Posted October 10, 2013 Easy once you know how to understand the feed back of a bike. Lean throw fuel at it. Rich take it out till it is just starting to show deto and then back off a bit. Or you could be conservative, but let's face it. Turbo bike owners aren't very conservative on the tune up when it really matters. (Note: that last statement depends on MY idea of conservative not yours) Quote Link to comment Share on other sites More sharing options...
Coupelx Posted October 10, 2013 Report Share Posted October 10, 2013 From a car perspective you cant tune by detonation as the margin for error is very little at high power to displacement levels. The power happens fast and violent. Quote Link to comment Share on other sites More sharing options...
