Stock 500EFI dyno sheet
 
Anyone have a dyno sheet they can post or email of a STOCK 500EFI? I tried to search for one but the search function picks up on way too much.

you want it with the gil headers or cmi headers ?

Either or both will work. But I thought the EFI only came with CMIs?

They make about 520 hp and 570 ft lbs

Thanks guys I'm looking for an actual sheet so I can see the numbers from 3000 rpm up.

Disclaimer: this is not my engine, not my data, rather it is info someone posted as a legitimate stock 500HP dyno test. With that said, it looks correct.

The 470hp is at the prop and should cover an engine at the low end of the production variability.

Cutting and pasting from Excel was a little messy. Here are the columns

1) rpm
2) hp
3) bsfc in lb/hp-hr
4) fuel consumption in gal/hr
5) torque in ft-lbs
6) BMEP in psi

If you want the Excel file, post your email and I'll send it to you.

Thanks ECeptor that's what I was looking for.

I have one that compares EFI and Carb gill and cmi headers.

I will email it to you if you post your email or send it to me.
