Borowski Race Engines, Inc. most popular crate engine for street is a Whipple supercharged LS7 which puts out 1,000 horsepower on pump gas. Peak torque is well over 900 lb-ft. Thanks to the supercharger's internal bypass, you go from cruising under vacuum to full boost in milliseconds. The G's of the resultant acceleration are what every gearhead dreams about. Unfortunately, that instant acceleration can turn into a nightmare if your drivetrain isn't ready for it.
Transmission people talk to each other in torque curves but talk to customers in peak horsepower. The torque from our Whipple supercharged engines comes in hard and at low RPM. This is very different compared to say a turbo engine where the torque steadily rises and comes on smoothly. We knew that we needed to have special transmissions built specifically for our engines to keep our customers happy and on the road.
Hughes Performance is widely considered to be the best major builder of high performance automatic transmissions. We approached them to work with us on this project and the result was Part Number BRE049345.
The internals of this transmission bring it a 1,500 hp rating from Hughes which basically allows it to handle torque our our Whipple supercharged LS's.
It's designed to work with a shallow pan and that is huge for street. Other vendors require a deep pan to "protect their transmissions". The problem is that the lack ground clearance can kill you if you hit something driving down the highway, or it can wreck your car pulling into a driveway with a high curb.
Thinking about doing some road racing at the track? What about doing Woodward Avenue's dream cruise in Detroit? Either one of these will heat your transmission fluid. Our design incorporates a threaded AN fitting for easy installation of a catch can to avoid laying down a smoke screen.
We keep these transmissions in stock for IMMEDIATE SHIPMENT and THERE IS NO CORE CHARGE.
Need a torque converter to go with it? We have those as well (HPI25-30LHD, cost $999). If you need a stall speed that we do not in stock, it can be drop shipped to you from Hughes within one business day.
