Screaming Dyno Video: Lingenfelter Spins Their Flat Plane Crank LSX Race Engine to Nine Grand

The men and women at Lingenfelter certainly know how to build horsepower. They’ve got everything from bolt on parts to full boogie racing engines available for sale. If you are going to be in the engine business, constant development and testing is necessary. Lingenfelter accomplishes this by racing their stuff. The late model Camaros they have out assaulting drag strips across the country do a great job showcasing their prowess in building grunt power. We’ve spent the last couple days in and around Lingenfelter Performance Engineering and at the amazing Lingenfelter Collection in Michigan. We’ll be showing you lots of stuff about our visit in the coming weeks but for now let’s take a look at this cool video from a couple years back.

In this video, you’ll see a 358cis LSx engine spun up to a screaming 9,000rpm on the pump. This engine makes over 600hp naturally aspirated, which is awesome, but really brought tears to our eyes when learned that these pulls were prior to the installation of a 76mm turbo. Yowza!

The sound it something to pay attention to. This engine has a flat crank in it, meaning that the throws are 180-degrees apart rather than the standard 90-degrees in a normal V8. The sound difference, especially at low RPM is really neat! This engine was developed by Graham Behan, the Chief Engineer at LPE for one of the company’s drag race cars. Behan spent many years as a lead engineer at Lotus and was instrumental in the development of the awesome LT5 small block. He’s been at LPE since the 1990s and his creative streak and developmental mind are still hard at work making horsepower in today’s advanced engines. This flat plane project was just flat nasty when it was rolled out a couple years ago.

While this didn’t happen last week, it still deserves a look because the motor is AWESOME.

    Seems like I remember WJ doing something like that with a flat crank back in the 1980’s back when he was running the big boxy Olds. Besides sounding like a v6 it ran within 2 or 3 hundredths of his normal combination at the time. Think he was bitching about not being able to balance it.

    flat plane is crazy, but fun to hear. Sharing journals will never balance, it is always a game. Still needs a benz crank throw, separated journals at 180..balance is there. No one built one yet…it wouild simply dominate with 25%-30% less liters. What market wants to be embarrassed?

    b3m, i dont know what you mean by you can’t balance a flat plane crank, it can be done. Look at the Ferrari 458 Italia, it has a flat plane and is perfectly balanced.

    Doubtless it is a very powerful engine and clever as all hell but…can’t get my head around its noise….LS motors, even stock, sound weird – this takes that weirdness to a new level…back in the 70’s (in Australia) most of us couldn’t afford V8’s ( they arrived fairly late on the scene in Aust and were a bit exclusive ) so plenty of people tried all sorts of trickery to make their straight 6’s sound sorta like a V8….that’s what this sounds like…
