Do you a want a driveable engine that puts out incredible torque delivered instantaneously at low RPM? No interest in waiting for turbos to spool, or for the RPMs to get high enough so the nitrous will kick in? Are you looking for a package that fits under a standard hood and does not take a ton of fabrication work? This supercharged 427 cubic inch LS is for you!
The twin screw 2.9L Whipple has been a best-in-class product. It is not a re-branded OEM mass production piece. The screw design and built-in intercooler provide high boost with a minimum of heat for more power. Characteristic of most twin screw designs, it has an internal bypass allowing it to cruise under vacuum. Put the hammer down however, and the bypass slaps shut sending you from minimal torque to up near 1,000 lb-ft in a heart beat. It is an awesome experience and it explains why this has been our best-seller since it was first introduced, but it is not a static design.
THE BIG NEWS IS THAT WE ARE SOON GETTING THE NEW 3.0L WHIPPLES WHICH ARE EVEN BETTER!
We will be replacing their 2.9L supercharger with this new 3.0L design for our engine builds as soon as our order arrives. Estimated shipping date from Whipple is March 15th. If the difference were just 0.1L in supercharger displacement, it would be no big deal. The 3.0L loses the jack shaft which in turn raises its max RPM. The higher max RPM will allow us to make higher boost and that means more horsepower. It will also run cooler than its 2.9L predecessor.
Our current 2.9L LS builds are rated at 1,075hp on pump gas. Our 4.5L Whipple typically run around 1,275hp. We are thinking the new 3.0L builds will do 1,175 - 1,200hp. That will be a lot more horsepower for the money!
Until we get our new superchargers, build and dyno the engines, we can only offer videos of the 2.9L. You'll get the idea.
As explained in the video, we put a lot of effort into selecting the best parts. Our platform is the Dart LS Next SHP Pro block. Among other things, it boasts: six bolt head capability, priority main oiling, far stronger bottom end design, thicker deck surface, longer cylinder sleeves and better metallurgy than its lower cost sibling. The 4.125" bore is filled with Diamond pistons mounted on Callies Magnum fully-counterweighted crank and matching Ultra rods. The crank's 4.00" stroke yields 427 cubic inches. Lots of reasons we don't push it to 454 ci. Give us a call if you want all those details.
Our custom grind COMP hydraulic-roller cam core is made from nickel-chromium-molybdenum steel alloy for an incredibly hard and durable finish. The cam lobes are also micro polished to achieve the perfect surface finish. These cams look so good it's a shame they are buried in the center of the engine.
We use All Pro heads with COMP's NEW Max-Lift BSR shaft rocker system for valve train stability. The heads are customized with CNC porting on our 5-axis and further tuned up by us on our Newen Contour CNC seat and guide machine. Crowning the heads are our custom billet valve covers with coil relocation brackets to combine great looks with superior function.
A Holley Terminator X engine management system directs the show. It is included in the package with the tune from your dyno session to make installation plug and play. The Holley unit can also control the available water-meth injection system which will chill the inlet air and improve performance under heavy load.
The 3.0L supercharger and matching serpentine system are available in either a black (standard) or optional polished finish. Talking about the serpentine system, no skimping here either. The 225 amp alternator will easily handle the electronics typical for modern restomod. The PS pump can be ordered either with its own reservoir or with a remote reservoir and fittings for hooking up your Hydratech brake boosters. The serpentine system and valve covers are also available upgraded to a polish finish.

- These engines are not pollution compliant and are intended for transportation use only in pre-pollution controlled vehicles.
- All BRE engines are individually dyno tested and tuned. Customers will be supplied with video of their engine's dyno along with the dyno and build sheets.
- Dyno results on the same engine are influenced by atmospheric conditions. The same engine can easily test +/- 2% different on horsepower depending upon ambient conditions. The engine you receive will have completed its dyno session at no less than 98% of rated horsepower with the tune we provide.
- The photos representing our 2.9L Whipple engine design show a variety of customized builds and also reflect its design evolution. As such, there will be some differences in appearance and parts from what is shown in some of the pictures and videos.
