        Thanks Mike, 30MM carbs. 310 #of static static thrust. max RPM is 4040. Fuel burn at cruise (3000pm)is 2.3/2.4 GPH. That s up from 1.9 with the stock carb. But

          Thanks Mike, 30MM carbs. 310 #of static static thrust. max RPM is 4040. Fuel burn at cruise (3000pm)is 2.3/2.4 GPH. That's up from 1.9 with the stock carb. But the throttle response is fantastic. The mid range power seems to be up. For me the gain in burn was worth it.

            How much more thrust did you get with the dual carbs compared to the previous single carb? [Non-text portions of this message have been removed]

                Hello friend, I honestly cant claim any extra thrust. It would have been nice, but it was not the main objective. My set up gets around 310# thrust. What was important to me
                was this.
                1. Better throttle response. Our elevator is the throttle. It now is VERY responsive.
                2. Removing the long intake runner helps eliminate carb ice. 

                3. It has better mid range torque. I'm very happy with the over all results.
                       Thanks for your interest,
                                                   Darrell

                      Throttle response and the thought of carb icing was just to much to not consider. I can tell you this. You may have noticed it did not like the 2400RPM range. It stuttered there reason  is the motor was designed to run @3600RPM, meet Carb requirements and emissions. Any other throttle opening was less than perfect causing rough running. 
                      This fixes ALL of them! Idles smooth. Pulls hard through the mid on up. My red line is 4040 RPM. I might also tell you this motor is not stock.  The carb set up was just the final icing on the cake.

                                      I see. Thanks for the info.  From what I understand they are all the block with different internals. I have a real good relationship with the factory rep.

                                        I see. Thanks for the info.  From what I understand they are all the block with different internals. I have a real good relationship with the factory rep. I'll check in on that. In a PPC we dont spin the motor at WFO but for a few seconds at a time. On our craft more power = climb. We fly at a fixed speed no matter the RPM. Unless we have a tail wind our constant speed is around 27/ 32 MPH depending on our weight. That being said the only reason we need more power is to carry a heavier load or to increase ROC.  So we are pretty easy on our motors
                                        over all.

                                          Hi  E,
                                          I talked to the factory rep at Generac. I inquired about the 38 HP motor. Gary kind shrugged his shoulder. Said " well yeah" He said it was an advertising manipulation to compete with another MFG bigger CC motor. He said it has a few little difference. The biggest was the cam. Witch I have in my motor.

                                            It seems that according to the rules of the powers that be..... Government. That so long as your HP claim is with in 85% its ok. So......

                                              When I built my motor. I had ordered all the parts needed under the guide from Gary. Together with the head porting, free flowing exhaust, pistons, flywheel etc... I feel pretty good saying my HP is around 50. Using the 85 % rule Don't think I can be called a liar. Wink.:))

                                            Hi� E,
                                            I talked to the factory rep at Generac. I inquired about the 38 HP motor. Gary kind shrugged his shoulder. Said " well yeah" He said it was an advertising manipulation to compete with another MFG bigger CC motor. He said it has a few little difference. The biggest was the cam. Witch I have in my motor.

                                            � It seems that according to the rules of the powers that be..... Government. That so long as your HP claim is with in 85% its ok. So......

                                            � � When I built my motor. I had ordered all the parts needed under the guide from Gary. Together with the head porting, free flowing exhaust, pistons, flywheel etc... I feel pretty good saying my HP is around 50. Using the 85 % rule Don't think I can be called a liar. Wink.:))

                                            Darrell the 20 thousand watt home stand buy generac v2 is the largest horse power at 38 hp.there are a lot of parts that are different in the 38 hp as apposed to the 30-33 hp engines. I have the part no of the good parts for the 38 hp engine if u wont them. I would not blink at turning my generac at 4000 rpm.E.

                                            Hello There are simple to build flywheel dynos you can build  A hub and a truck flywheel rated at your RPM and a pickup to read RPM it measures acceleration

                                              There are simple to build flywheel dynos you can build  A hub and a truck flywheel rated at your RPM and a pickup to read RPM it measures acceleration of the flywheel BTW the heavier the more accuarate it is If you start with a new factory engine set up as per the factory test spec (aif filter muffler ect) it will act as a calibration point Simply vary the input mass to match the factory numbers Reducing the factory flywheel weight after set up will require recalibrating

                                               BTW a dyno run is a few seconds idle to peak
