This chart is my actual configuration (Q-Jet 750 and optimized timing). It is the most accurate data I have. "356 HP at 4700 RPM" This graph is an earlier dyno run and not as accurate as the chart. I am including it to show the wide band at which peak HP occurs: Here is the Berkeley chart...

hello fellow boaters , I have a question about getting a motor dyno'd what all does some body need to bring with them to a dyno session ,headers,fuel & how much ? what all are you allowed to do or do they have to do it check spark plugs adjust timing adjust carb ?.....and where /who has dyno in...

Some of you may like the powerband and this is good example of OEM Type GM heads and the "ISH" I talk about.... Customer called this winter with Land Speed Class project. She is a 4 speed camaro. With gearing he needed peak power at around 7400. 565 Combo 14 to 1 BMF385 Customer was on...

I'll be running a flat tappet cam in the 545 and would like to break the engine in (as well as tune and make a few pulls) on a dyno. I'm looking for a shop in/close to Orange County that can deal with the peculiarities of a jetboat engine on a dyno.

I am looking for marine shops that also do Dyno Tuning. I need a shop that I can just drop the boat off and they can pull the engine dyno it and then put it back into the boat. I know Boost Power has a dyno and I haven't crossed them off the list but they are a little far from me. I am looking...

Starting on the dyno room. I am frickin tired of working on the shop. I'd prefer to go back to drinking every night. BUT, that doesn't accomplish anything. So.... most rooms have the cold air (fresh air) come in right above the engine. I guess that makes sense.... if only running carb...

I haven't done a build thread in quite some time and thought this one might be worth posting. Very basic engine. No crank trigger, no vac pump, no fancy oil pan, no exotic valve train, just a good solid build that should last a long time. Here's a run down on the details: Dart BigM Sportsman...

Had my engine dyno'd and looked good when done in 500rpmincrements, 850hp @ 5500 rpm and 890 hp @ 6000 rpm. But when he did the test in100 rpm increments the hp #s were all down below 800 hp? He said it was not accurate @ 100 rpm increments. Why would this be?

I came up with this equation to predict performance gains when adding a vacuum pump. I'd appreciate it if you would run the numbers and report back how close the equation is to your actual measured gain. Pretty sure it's nearly dead nuts, but I've certainly been wrong before. Vacuum in...

Is this somewhat accurate?

Some of you know i was having problems breaking rocker parts. I decided to have a second set of eyes take a look. Everything checked out good so we went to the dyno to see if we could get it to break under the microscope. Well 17 Pulls later and its still together. Only thing i changed was...

Just listed an outboard engine dyno in the other section if anyone is interested. Thanks

International model 2000 outdboard engine dyno works good comes with 5 prop shaft adapters and everything needed to use it needs a little clean up this was a $3400 dyno Asking $800 760-326-5303. Thanks

new blower carbs, tune off plugs or dyno? anyone have a dyno near canyon lake? and williing to do it for cheap haha picked up some new carbs for my 540 off craigslist, they were done by CJ engineering with a build sheet and a dyno sheet on the motor, 1080HP on a blown 540 10# of boost i'm...

How to use ALL of the air in a dyno cell. Almost cant stand to listen to this guy talk. But hard to argue with his results. NRE Encounters Black Hole While Testing Engine. 2500 HP 632CI BBC | Speed Society

We got a late start, so we only made 4 or 5 pulls. To get a base line we started with 27 deg timing. Carb jets 93 square. Pulleys, one to one = 5 lbs of boost. 4500 rpm max. Last pull was 27 deg. 93 square, 8 lbs of boost. Dyno locked at 5500 rpm max. Results as follows: 927 HP. Running...
