9500RPM Naturally Aspirated Mod Motor Dyno 

right on then. didn't know that. either way it is a SICK ride!

don't forget about the 6.8

@Anhaedra It's all about how deep your pockets are.

BEAST!!!

and people say only the imports can rev high :P

@helloman1976 no one makes an off the shelf cam with proper lift/dur for 9500 rpm

Cool! Les

@FatedRaver sounds healthy to me , there are many reasons a motor will lay down, mostly tune and driver error though, a build error on the dyno at 9500 would def show weakness/ dam due to build error. over boost over shoot over rev, come to mind. What did the 1st filter look like? Clean? If not why didn't someone pull it down? Sounds like driver/tuner error.

@UnderdogModular if you got 35k to spend on a engine just spend an extra 5k and get a full blown nascar engine that redlines at 10,000 rpm

If it's a 5.4 the 4.165 is making some insane piston speed so kudos to the build even a shorter stroke is achievement. Obviously well put together or we'd see grenade activity

um, okay, it IS cool, don't get me wrong, but a 5.0 isn't a mod motor, the mod motors are the 4.6 and 5.4..just clarifying.

What's your valve train look like in this thing? Did you do a custom CAM grind so you could REV this high or are you just rolling the dice or what? What's the timing look like at WOT? How many degrees etc...thanks

u see this is the bad thing about NA engines even tho its 1000hp ON THE COMPUter it real horse power it get down on the floor ie BHP will be about a fraction of the 1000 HP i know Turbo chargeers are look down upon becuz of their lag but whit a (MSF) Misfire system it can become just as reponsive as a NA engine

9500 is great and all but not that big of a deal .My old landlord has a 500ci bigblock that has a 10500k redline naturally aspirated thats WELL over 1000 hp.Just takes money.

To run a 9.80 in a 2700lb car only requires a lot of traction and about 560hp at the crank (roughly), assuming the rest of the car is set up correct.

How long do high rpm motor last?
