| Post subject: | Guzzi car dyno results |
After doing my best to get the car right,I took it to the dyno today,first pull was 186.5 at 5450 rpm max torque 195.1 at 4850. 11 pulls later,,, changes inbetween,dyno guy and me got it to 189.0 @5450 max torque 200.8 @4850. He was very surprised and a little pissed off that he only got 2.5 more hp out of my seat of the pants tune,AND alot of help from this list,THANKS ALL,moto guzzi mark |

You should be right on the 14.00 boundary. Slant will have a broader HP peak than most, so you should pull into the 13s. Heck, if you ran high 13s before, this motor should have a little more stank, right? Lou |

I think you will be pleasantly surprised with your new set up. My car dynoed at 186HP with the a 236 degree at .050 cam and 500 Holley 2BBL. With that set up it went 13.96 at 97MPH. Your car is 100# lighter and more importantly you have the auto trans that soaks up a lot of power on the dyno but will get you down the track much better than my wide ratio OD trans and granny shifts. You shold be good for middle 13s in good conditions but it won't go that fast at Las Vegas. Have fun. |

Max, if you have 189 at the rear wheels, your engine should be 200 hp or more right now. Not an expert but I thought the rule of thumb was about 15% loss from engine to pavement. |
