840Hp Stealth B7 NASCAR V8 Engine || ONBOARD New Record & DYNO

This is the insane Stealth B7 of RR Racing, driven by Jan Oivind Ruud and the new 2WD Record Holder at Norges Raeste Bakkelop, the most prestigious HillClimb event in Norway, getting dangerously close to former WRC Champion Petter Solberg´s Overall Record in the process. Powered by a Nascar V8 Chevy SB2.2 V8 enigne in NAturally Aspirated form producing 845Hp and scraming all the way up to 9.200Rpm, this unique machine takes the obscure Stealth chassis base to a whole new level featuring full Carbon Fibre bodywork and tremendous Aeordynamic package capable of 18600Nm of downforce at 220km/h, Hewland gearbox NLT6 sequential Gearbox, DRS, Carbon Brakes (380mm at the front and 350mm at the rear), Titanium exhaust, magnesium wheels among a whole host of other goodies. Here you can watch it on the dyno and on Max Attack mode at the Hill on its way to the Record:
00:00 - Dyno
01:00 - Full Run w/ ONBOARD

What a beast! This thing is an amazing fusion of American V8 muscle and European precision engineering! I love it!

[@theColeHardTruth]

g5084 yeah of course! It's just more European here 😁

[@theophilhist6455]

Even more amazing is that it appears the fuel is being punched down the throat of that hi-rise intake manifold with a carburetor !

There's just something about the sound of a cross-plane crank V8 that revs to the moon... The noise!! The glorious noise!! I've also been sitting here playing this from start to finish over and over again because of 1. The sound and 2. The sheer brutality of this monster! This thing looks like a handful of handfuls!

[@mojitocod]

Are you sure it's a cross-plane that reaches 9200rpm? Seems improbable...

[@NorwayVFX]

@@mojitocod Nascar engines have been cross plane for ages and rev to the moon no problem, several people have managed to rev both the old Chevy small blocks and the modern LS engines to 10k+ with cross plane cranks.

The quality of the build is overall is pretty high up there ;)

[@antoniosvorrias9100]

All American v8s should sound like this. Always loved the b6 and the b7 is pretty close to that. What happened after the finish line was surprising and nerve wracking!😮

[@markholroyde9412]

It sounds crap for a NASCAR engine in realty, sounds like an average LS.

[@assaultlick2169]

​@markholroyde9412 the nascar sound has alot to do with the boom tube exhaust they use. Looks equal length header here and sounds alot smoother

[@yetkinkaracal3346]

The king of NA engines. I mean +9000RPM from an American V8?!! WOW👍

[@griffinfaulkner3514]

Top-level NASCAR engines are some of the most unhinged racing engines on the planet when they don't have any restrictors on them. What's scarier is this is a fairly old engine design, the current equivalent to this engine, the R07, is easily capable of 900+ horsepower and 10k RPM for short runs. At those levels, the piston speeds actually exceed what you find in F1.

[@replynotificationsdisabled]

PUSHROD too

[@replynotificationsdisabled]

@@griffinfaulkner3514 because of the longer stroke though

[@griffinfaulkner3514]

@@replynotificationsdisabled Even so, that's a bigger, heavier piston moving at insane velocities. The fact that those engines can hold together as long as they do at sustained WOT is staggering.

[@GTKdje3]

That’s really not surprising given they have made high reving v8 nascar motors for decades? Heck they have built over 10,000 rpm motors but rules limited them to 9500 rpm. In 60s there were nascar motors reliably turning over 7500 rpm.

[@B_M_A]

Used every bit of tire until the end! Absolutely ripping.
