MAPerformance: EBM Stock Block HP Record 501whp/464wtq (STD) | *New Video Added*

DAYUMMMM! Congrats Adam, Very impressive!

Jeez. Stock internals still? How high will they go? They can't be safe at that level yet, definitely interested in seeing when they finally let loose.

Can you measure your compression somehow? I'm curious to see if the rods are squished a little bit haha. I've had a friend with a terminator pull his heads to find his pistons were sitting quite a bit low at TDC.

Nice results, congrats. When the fuel system gets sorted out, can E30 make comparable power?

Please don't blow it up before this weekend.

It have good axles? Gonna run a DR?

I have the factory PTD height from our second engine that we are building. We got it as a complete factory sealed longblock so the specs are dead on. I will compare to the motor that is in the car now when it comes out to see what the measurements are.

We are definitely in the territory of this engine letting go, but the tune is so solid its hard to say when it will actually let go. I'm going to assume it will be the ignition having a misfire that might make this thing go. The cylinder pressures are intense I'm sure.

E30 was maxed out at 445whp/430wtq. Even with more fuel there wasn't enough timing left in it to make anymore power. E85 will be a different story.

The car is completely stock besides our production products, and a prototype rear trailing arm bushing. I will probably put some Steeda products on the car before we hit the track. I have their full 2015+ product line stocked right now and it is great stuff. Can't wit to get it on!

No drag radials, stock tires. Will get some radials, wheels, and hopefully a clutch solution for when we go all out with the built motor.

Nice Work.

For us math people... How many gallons of what Octane plus how much Race gas?

Simply.. tuned roughly for what octane tune?

Thank you! Are you foaming at the mouth yet?

Who.. mee.. err.. uhm..



Not at all!!

Wow...

This must feel like an animal on boost. Well done!

Thank you. Going to take it out on the street tomorrow. Going to have a smile on my face for sure.

I am not going to be able to do the MAP treatment for at least a year. I can NOT believe how far you guys have taken this platform in such a short time. When I am ready to pull the trigger it will be Your parts that spoil my baby.

This seems a bit premature, Adam. What does this graph look like with the widely practiced SAE correction factor? It would also be excellent to see run conditions. I'd appreciate if you removed the "New World Record" portion of your post title. It is very misrepresentative of facts.

SAE:
"SAE (Society of Automotive Engineers), USA. Power is corrected to reference conditions of 29.23 InHg (99 kPa) of dry air and 77 F (25°C). This SAE standard requires a correction for friction torque.

STD:
STD is Another power correction standard determined by the SAE. Power is corrected to reference conditions of 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5°C). Because the reference conditions include higher pressure and cooler air than the SAE standard, these corrected power numbers will always be about 4 % higher than the SAE power numbers. Friction torque is handled in the same way as in the SAE standard."

There are few standards used in the dyno world for gathering HP and TQ numbers, UNCORRECTED, SAE and STD. Uncorrected is NEVER accepted in the world of dynoing and tuning as it does not factor in any weather conditions etc. Now here is where the big debate comes...is between SAE and STD. SAE (Society of Automotive Engineers) is the MOST ACCURATE AND WIDELY ACCEPTED FORM OF MEASUREMENT when it comes to the world of dynoing.

Most people know that showing STD numbers read higher but not many know why. SAE represents more realistic standard conditions, STD artificially boosts numbers.

Here is some quick math (using assumptions and round numbers):

STD:
Air Temperature: 60F
Absolute Pressure: 29.92 inches Hg
Relative Humidity: 0%

Relative Horsepower : 104.8%
Air Density: 1.223kg/m3
Relative Air Density: 99.8%
Density Altitude: 67feet
Virtual Temperature: 60F
Vapor Pressure: 0 inches Hg
Dyno Correction Factor: .955

SAE:
Air Temperature: 77F
Absolute Pressure: 29.23 inches Hg
Relative Humidity: 0%

Relative Horsepower : 100%
Air Density: 1.157kg/m3
Relative Air Density: 94.4%
Density Altitude: 1952feet
Virtual Temperature: 77F
Vapor Pressure: 0 inches Hg
Dyno Correction Factor: 1

Not here to start a war, genuinely curious! --- In this industry we must take care and ensure we are comparing apples to apples; especially when record breaking is involved. Its the reason we go out of our way to obtain DynoJet numbers; to give the community valid, indisputable, comparable results... so long as the proper correction factors are being used ;p Thanks!

Absolutely amazing! Great job!!
