You're over 100hp off, from "pretty damn good".
A competitive Dirt Latemodel 410" engine will make over 800hp, with a cam in the low 260's at .050", and has to run 50 lap races.

?? Not sure i follow. I understand him to say 350 jetting actually makes near 400.Stan Weiss wrote: ↑Mon Oct 07, 2019 9:40 am What is your weight, et and mph?
► 1100 - 700 = 400 - if greater than 700 this will be less than 400
► 350 / 50 = 7
► 65 * 7 = 455 HP
► 70 * 7 = 490 HP
► (400 / 350) * 50 = 57.14 HP per 50 shoot
Need to work on your math, Has your nitrous system been flowed?
Stan
With heads and cam and bottom end setup for big hp nitrous?
400hp is not big hp nitrous.
Not saying 400 is big but he could be trying for 600 for all we know. Regardless, for a dedicated nitrous mill optimizing valve seats, header sizes, piston/ring pack sizes, bearing clearances, oil weights, chambers and cam durations and lifts would be different than for na engines and usually i would have thought would hurt power if dyno’d on motor alone.CamKing wrote: ↑Mon Oct 07, 2019 10:22 am400hp is not big hp nitrous.
If you took a Dirt Latemodel engine, and converted it to run 1/4 mile drag, with 400hp NO2, it would make even more N/A power then it makes in circle track trim. Just the added .100"+ of lift would be worth a good chunk of power.
He could be trying to add 1,000hp of NO2, for all we know. He's big on questions, but short on information.Orr89rocz wrote: ↑Mon Oct 07, 2019 10:32 am Not saying 400 is big but he could be trying for 600 for all we know.

Along with the info you've given,
Mid .700's for lift in most cases. Some as high as .800"swampbuggy wrote: ↑Mon Oct 07, 2019 8:59 pm Hello Mike, you mentioned 410" Dirt Latemodel engines duration numbers, how much gross valve lift do those guys run ? and what is their peak RPM ? Thanks Mark H.
