Mr. Turbo GSXR
Every time a new engine design comes out from Suzuki, it usually pails the performance of the previous design, and the ’86 GSXR lived up to that scenario in spades. With it’s new oil cooled design, and more efficient head, this engine had what it was going to take to make the step in performance in the mid ‘80’s, and it did not disappoint. This bike took to turbocharging like it was made for it.
The plain bearing crank, and forged pistons allowed turbo applications to run as much as 25lbs of boost on racing fuel without touching the engine. This is a very reliable engine under extreme conditions. The first bike to be fitted with a factory programmed electronic ignition system, which eliminates the need for an aftermarket ignition system, and makes for an excellent curve for turbo applications.
Boost / Horsepower
10 lbs / 185 hp

30 lbs / 300+ hp
With the increasing use of chat rooms and an endless number of places to get information these days, be careful, much of it is bad information. Every Horsepower number claimed by us on our website, over the phone, or any advertisement is based on “rear wheel” numbers from our DynoJet 250 dyno. Rear wheel numbers, at the pavement, confirmed by other dynos around the world, no exaggerating, no “pie in the sky”, and no bragging… just fact
- 0-8psi: 92-octane pump gasoline, octane booster recommended.
- 9+ psi: Race gasoline for turbo and/or supercharged applications (VP C16, etc…)
Race gas and octane booster are not required when driving the bike at normal speeds and when not applying boost. As you will learn, a turbo is only in boost when you twist your throttle telling it to do so. A turbo is not an uncontrollable device, and using common sense and throttle control will regulate how much and when boost is used.
Octane boosters can be deceptive. Be sure that the booster that you choose to use is acceptable for turbo or supercharged applications as many are not. In the past, we have used 104 Octane Booster. There are two versions of this product available; a red bottle that is intended for light duty street engines, and black bottle that is usable for turbocharged applications.
