    Don't forget direct cylinder fuel injection. They pressurize the fuel to like over 2000 psi and inject it directly into the cylinder. They have nearly unlimited options (compared to in the intake injection) to modify when the combustion happens. It's helping them wring extra HP and mileage out of small motors.

    There is a lot of power and inertia reduction sitting on the table with this bike.
    Get the weight down. The wheels weigh what 36 and 24 lbs some one said. The stock pipe has to weigh 50+ at least. Lightweight tires and wheels. Get rid of the rear fender assy and your down under 600 lbs I would guess. That takes a lot of pressure off the drivetrain.

    That's what I expected.

    Short shifting rarely is beneficial. People often forget about the fact that the even though power may be dropping off a little as you continue past the peak, it will be even lower when you shift and find yourself farther down in the opposite direction. A good rule of thumb has always been, when it stops pulling, shift. Now with modern technology and rev limiters, right before she gets cut off by the rev limiter is optimum.

    PS Still looking for someone with some before and after with the new Cobra Power Pro.
    Im not posting any sheets with this but I can tell you that a month and a hlf ago I put my bike on the dyno with my PCIII. Last week I put the cobra Power pro on and put it back on the dyno. A different dyno. My numbers were exactly the same as they were with the PC. The bike seems to be so much smoother with the cobra. The reason I bought the cobra was to cut down on dyno cost. I have been running the Raw Superheader. 2 1/4" head pipes. Yesterday I put the McCoy Supertrapp on the bike that I just recently bought from HyperPete. Man It sure feels lik there is a good difference. I hit the rev limiter so much faster. That is the advantage of the cobra for me. I didnt loose any power from a so called perfect tune from being on the dyno and I can mod away with out having to go get tuned! I just Go!!!!
    I think its an excellent Unit!!!
    This sheet is from tuning in Dec 2010.

    This was my best time last time at the track in March. Spinning was a problem. Im #34 the other is a buddy on a raider.

    This is the pipe I bought from Pete. The sound and Performance of this shorty is awesome.

    Thanks for the info and opinion. That is some serious HP--146. And you got the same on a different dyno. Impressive. Thanks for posting.

    Very cool kenny. The torque curve looks real choppy down low. The tale lies in the fuel curve on both if you have those and then maybe another time slip.
    I am charting my slips and times. My bike goes on the dyno this week and I will be at the track thursday to see if it made much difference.
    My best times so far are 60 foot. 1.771, 330 ft 4.910, 1/8 [email protected] I will be able to tell right away what the auto tune and quickshift did for me. Glad everyone is enjoying the cobra. Would have been cheaper for me but they said not to use it for what I was doing. No timing retard. Also the PCV will let me raise the rev limit in top gear to 8000.

    Sweet! It's a sticky. now. Thanks guys and gals for all your interest and input. I think this will continue to develop into a nice thread.

    When I get an extra hour or two I will do some searching and post some links to some older Dyno threads I've come across that were very interesting. In the mean time, if you find some or know of some relevant links, let's get them in here.

    Going on the dyno tomorrow at noon. 100 degrees here. Oh well. The tune oughta be a safe one at that heat. Anyway We decided to pull the secondary throttle valves. He does this to his race bikes and tunes the flat spot out. Also my air boxes are ported so I want to see what that does. Last we are adding the extra 500 rpm to the redline. Go Big or go home. Wish me luck. I will have pics and video to post.

    If you dyno that beast all the way to 8,000 rpm, we aught to see some really tall numbers. Hopefully you'll be able to get enough air in the cylinders to support that RPM. Can you explain what you mean by "my air boxes are ported?"

    Look at these, The whole inside of the housing is gone so there is no restriction to the pipe going up. And the air filter is a 95 Camero 350 on both sides cut down to fit inside. Lots bigger than the stocker. Also I am going to be doing a Ram Air system on this using my Edelbrock outer as a mold for the scoop.

    Interesting. So, are you willing to do a pull with a stock/uncut airbox with K&Ns and compare your handi work? Are you blocking off the back of the box and opening up the front cover, ie., Duck's?

    Keep us posted.

    First I ran it like this, homemade Velocity Stacks, then I went to the edelbrocks. Some kind of Ram Air is coming, I am kicking around ideas right now.

    If we look at Kennys dyno sheet you will notice that at 7400 he is still climbing at a pretty good rate. If he had another 500 rpm he might peak. That is the difference with his motor haveing internal work done to increase air flow and rpm. I am only .25 seconds behind him i the 1/8 but a whole 6 mph behind. My bike is strong in the midrange but he is really pulling hard on top.

    Just got off the Dyno. 119.37 HP at 6800 and 112.78 torque at 4400. Waiting for the video to download at you tube then I will post the pulls and the shifter. The shifter is set at .65 milliseconds for a shift. That ought to make up some time in ET. I will post the dyno sheet as soon as the printer talks to the new computer correctly. BTW it was 100 degrees in the dyno room when we did this and he use std and 3 smoothing. You can see the fuel curve on the screen in the video.

    Default Hot day at the drags

    So Cal has been hit with a heat wave. The track surface was in the high 120's.
    That said I got a best time of [email protected] on a high 90+ day That is a pick up from a best of [email protected] on a 75 degree day. I lost a full .035 at the 330 ft and .077 on the 60 foot. The biggest thing I noticed is it spun like a teenager in his daddys corvette. I had to drop my launch from a best of 4500 down to 3500. And second gear at 7200 and a full throttle 65 millesecond shift gets me 20+ feet of rubber and a vicious kick to the right. The shifter worked awesome but I will have to go back on a cooler day to see like for like on track temps. The rubber was balling up on the launch pad. They had to sweep it almost everyother run. But all in all it was fun 12 runs and a bit of a faster et and speed. Lord I need some sticky tires.

    Sounds like a lot of fun. What tires are you thrashing at the moment?

    Default Quickshifter Pic

    Here is a picture of the Quickshifter solenoid and My falling apart muffler packing. It was blowing past the outside edge. Makes me think It might be a bit small of a tube. I am going to see tomorrow if I can get the shop to make it more than only 2 1/4 inch in diameter sitting in a 4 inch tube. But tonight I am going to ride it wide open.

    My baseline is [email protected] mph. That is what 119 hp and 112 tq gets me. Today was a good track and any more off the line it lifts the front tire pretty fast. So now it is time for the nitrous. Kennys bike makes 146 and 120 and runs [email protected]
    So 50 hp should get me hopefully 100 mph and very low 7's.
    I also know now without a doubt that my Cobra FI2000 makes almost exactly the same et and mph as the PC-V with the auto tune. Food for thought.

    Thanks for posting. Are the first two runs before any adjusting? Or with the F2000 set at 1, 2,1 or what? And what do you have the F2000 set at now? If so, those are some pretty significant gains. Interested because I am also running the F2000 and wonder how my butt is supposed to tell me how much to turn those little screws. I figure I could be off quite a bit and wouldn't know it.

    Also, do you "feel" the bike runs better than before according to the "butt" dyno?

    How much nitrous are you planning on? And is it a dry or wet. I know there are guys here running much bigger numbers that we are posting right now. So Far Kenny is the fastest N/A motor and Bigeh is the top of the leader board as far as posted times go. Come on you closet racers Post up some big numbers so we have some info to learn from.

    i am running a wet shot i have a few different nozzles a friend of mine ran the same set up and wasclose to 190 hp with 160 ft lbs of torque. i am not sure his exact numbers
    i think to start i am gonna go smaller maybe a 40 hp increase and go from there

    Ok after talking to the guys at Dynojet. I am going to be adding an Ignition Module 6-81 for the M109 and C109. It will allow a +-10 degrees and will allow an extra 500 rpm to any gear. Going to dyno the bike next week with the new module and custom map then the nitrous map will go on. We are pulling the pump and making changes in the pressure regulator. Costs me for 2 tunes but it should be really safe when we hit the bottle to 8000 rpm at the mile.

    Just got back from the Drags. Picked up a full MPH to 93 in the 1/8 tonight. The auto tune is really smoothing it out and making the quickshift transition less violent. So best aggrate numbers so far .415 r/t on a .400 light. 1.77 60ft, [email protected]
