230-240+ HP Package (1397cc/1430cc) – Price $6,300

We just can’t leave it alone! The porting and cams brought the Busa to new levels of performance. Now what will a piston kit bring? We had to find out!

Two flavors are available: 1397cc for everyday riding and the 1430cc for track use and the occasional blow-your-friends-away street jaunt. When they ask if you are spraying look at them like they are crazy!

265+ HP Everyday Rider Package (1600cc) – Price $14,900

One of the most reliable engines we have ever done!

We take our monster Big Stroker 280+ HP package but use a smaller piston with lower compression and make a reliable, multi-season everyday rider. An everyday rider that burns up the pavement!

A 9mm stroker crank and 84mm pistons gives us 1600cc. With a more streetable compression this combination runs on pump gas and eliminates the need for constant refreshing.

Package includes everything in the 230-240+ package plus:

  • Carpenter Racing Billet 72mm (+9mm) Crankshaft
  • Carpenter Racing Titanium Rods
  • ZX-14 Rod Bearings

280+ HP Big Stroker (1630cc) – Price $14,900

Our customers continually demand bigger, bigger, bigger…

We have been building stroker Busa motors for years but never before have we been so excited about it.

We combined our 240 kit with a billet stoker crank with titanium rods for a dependable 1630 cc displacement. Our palms were sweaty as we rolled it over to the dyno. The results were stunning!

280+ HP Hayabusa Big Stroker Dyno Chart

After some development on the fuel curve we came up with over 280 horsepower. By our calculations, 280 horsepower on a chassis dyno with a street tire equates to 320 hp at the crank – Now we are talking Pro Stock Power!

  • Carpenter Racing Billet 72mm (+9mm) Stroker Crankshaft
  • Carpenter Racing Titanium Rods

290+ Hayabusa Package with Plate Head (1630cc) – Price $21,300 (INCLUDES SIDEWINER EXHAUST)

This package REQUIRES a phone consultation.

Since the inception of Hayabusa, we kept our goal of a strong price-value for our clients. To keep costs down, we had to stay within stock components wherever possible.

At that time, we learned a lot about the engine and started realizing the limiting factors in the design. We thought we could go a lot farther if we removed the obstacles.

Instead of focusing on cost considerations, we would focus on winning alone. We wanted to take what we learned from NHRA Pro Stock racing and apply it to the continuing development of our Hayabusa program.

With the door open, we threw everything we had at it. We started with the bulging internals of our 280+ package, added our new exhaust pipe and port combination, performed radical cylinder head machining, and installed proprietary high-end components.

No one is doing what we are doing to a Hayabusa motor.

The results speak for themselves: over 290 horsepower and a gain of 1,000 RPM.

“We decided to break the mold of working around stock components,” said Bob Carpenter. “Now the gloves have come off. Whatever it takes to get the most power out of an all-motor Hayabusa, we are going to do. No one else is at this level. We have serious clientele that want serious power.”

Makes 300+ HP with an aftermarket ECU and fuel system!

Package includes everything in the 280+ package plus:

  • Carpenter-designed 4-in-1 high-diameter stainless steel exhaust with race-only megaphone
  • Carpenter Racing Plate Head
  • High-end proprietary componentry
