Supra competition clutch stage 2 how much hp

Frequently asked questions

What is the primary difference between a stage 1 and stage 2 clutch?

The main difference lies in the friction material and pressure plate clamping force. A Stage 1 typically uses an upgraded full-face organic disc for a modest increase in torque capacity with a near-stock feel. — kind of A Stage 2 uses a more aggressive material like carbon-kevlar and a stronger pressure plate, allowing it to hold significantly more power, often with a slightly stiffer pedal and quicker engagement.

Is a stage 2 clutch difficult to drive on the street?

For most drivers, a Competition Clutch Stage 2 is very manageable for daily driving. The pedal feel is slightly heavier than stock, and the engagement is more direct and less forgiving of poor technique. However, it is not an "on/off" switch like more aggressive racing clutches and can be driven smoothly in traffic once you get used to it.

Do i need to upgrade my flywheel with a stage 2 clutch?

While not strictly mandatory if your stock flywheel is in great condition and can be resurfaced, it is highly recommended. Installing a new performance clutch with a new, matching flywheel ensures a great mating surface, optimal performance, and prevents potential slippage or chatter issues caused by a worn component.

Factors that influence real-world performance

The advertised power rating is not the only factor. Several other variables can affect how well the clutch performs and how long it lasts: — sort of

• Break-In Procedure:as far as I can tell, a proper break-in period of 300-500 miles of city driving (stop-and-go) is key. This allows the friction materials to mate properly with the flywheel and pressure plate surfaces, ensuring maximum grip and longevity.
• Flywheel Condition:Installing a new clutch on a worn or glazed flywheel is a recipe for failure. — I mean Always resurface or replace the flywheel. just saying, an aftermarket lightweight flywheel can improve engine response but may introduce more chatter, right?
• Driving Style:Aggressive launching, clutch-kicking, and powershifting put immense stress on clutch disc and will drastically shorten its life, even if you are within recommended power range.
• Engine Power Curve:An engine that produces a massive, sudden spike of torque at low RPM is harder on a clutch than one with a smooth, linear power delivery, even if both have the same peak horsepower.

Understanding the role of a stage 2 clutch

When upgrading Toyota Supra, especially the legendary JZA80 (MK4), the clutch is one of the first components that needs to be addressed as you increase power. (well, almost) by the way, the stock clutch is robust for factory output, but it quickly becomes a weak link. I think, a Stage 2 clutch represents a significant step up, designed for spirited street driving and occasional track use. It offers a balance between holding power and daily drivability. The primary question for enthusiasts, however, revolves around its power-handling capabilities.

Competition clutch stage 2 specifications and hp limits

The Competition Clutch Stage 2 "Street Series 2100" kit is a popular choice for modified Supras. It typically features a high-performance pressure plate and a steel-backed disc with segmented organic or carbon-kevlar friction material. This combination provides a substantial increase in clamping force and heat tolerance over stock.

Specifically for the Supra's 2JZ-GTE engine, a Competition... The stock 2JZ-GTE produces around 315-325 lb-ft of torque. well, this means the Stage 2 clutch is engineered to hold approximately550 to 800 lb-ft of torque.

So, how much HP is that? For a typical Supra powerband, this torque rating translates to a reliable horsepower handling capability of roughly — more or less500 to 750 HPat the crankshaft. honestly, for cars at the upper end of this range or those used for aggressive launches (like drag racing), it's crucial to consider drivetrain shock and driving style.
