Here's the numbers I copied from the ExCel chart I made to convert the MA-M DynoLog to the DynoJet numbers.
It's a 17% factor

Heart Breaker +17%

Why Our Mainline Dyno Produces More Accurate Results

Inertia Dynos - like DynoJet dynos, measure power based on the length of time it takes to "spool up" two heavy steel drums within the dyno. Horsepower numbers are much higher because they are based on distance traveled / acceleration rather than force, at least 17% higher than load bearing dynos in our experience. Cruising air / fuel ratios are generally richer because they are based on wide open throttle conditions.

Load Bearing Dynos - measure power based on the force applied to the rollers when the dyno brake is applied. Loading the engine gives us the ability to hold the engine at various loads for driveability tuning and maximum fuel economy. All Mainline dynos are load bearing dynos.

load bearing to inertia dyno horsepower conversion
ACCURATE, DEPENDABLE, REPEATABLE RESULTS
The Mainline Dyno is widely described as the "no fudge" or the "unfudgeable" dyno, and is the obvious choice for dyno operators who choose an honest approach to business and do not want to be caught up in the debacle about why the same car can get differing results on the same brand of dyno, why the same car can produce inconsistent results using different dyno "modes" or even why a dyno needs different "modes" for 4, 6 and 8 cylinder vehicles.

The Mainline Dyno deserves its outstanding reputation for producing the same results from dyno to dyno, as a scientific approach has been taken that provides the highest degree of accuracy. No need for a special operating mode that reduces the ability of the operator to affect the results. No menu options for the dyno operator to "modify" results. There are definitely no cheat modes and no smoke or mirrors on the Mainline Dyno.

This graph is correct on MA's dyno compared to a DynoJet. It's dead on the money. MA took my car to a dyno jet and verified, 589hp on their dyno is 690hp on a dynojet. 2nd run the clutch slipped. Well, the tuning will continue once the clutch upgrade is finished.

Car has been delivered to MA. DC traffic is hell. Brian has a couple of vehicles to tidy up before he goes full out on mine.
It's in good hands.

Rusty · 02-09-2019, 02:23 AM

I figured you was in the process of dropping it off. Because you've been quite.

He’ll be fine; ready to see that “Beast” @Zdaz this year!

Spooler, have a safe trip back home... if you aren’t back already

Glad you had a warmed up window, to get it up the road

Already home, I got to meet everyone and talk about the build. I got lucky we had this freak warm up period. That worked out in my favor for sure. Hoping the car will be done the end of April at the latest.

LOL, The clock started last year on March 6th when I started this thread. I can see the finish line from here.

Brain did not let it slip his mind that I have a 1975 280zt. He was asking me questions about it on Friday. LOL He wanted to know if I was dedicated to the L28 engine. I started laughing. I would really like an RB26 for it on a standalone. Talked with the wife about it. Already talking about another build before this one is finished. Some things to ponder for sure. One day, this will happen.

Finish one project before moving to another. Otherwise the first will never get finished.

The 280z project will be several years away. LOL I have to recover from this one first.

RB swap the 370. Put the VQ in the 280.
