Guru Flywheel

[RETed]

So i have been toying with the idea of a Guru 4140 flywheel for sometime now. I prefer the natural aspiration routes as of late and one of the biggest places to free up some rotating weight is the flywheel. I have considered a few options but i have though about going above and beyond. Guru makes a flywheel spec'ed out below. Its very light, uses the 5.5 clutches which would make hi rpm operation a sound deal and would probably be the best thing possible if you wanted to go all out. Obviously its not the cheapest route costing about 800 or so for the flywheel (AUS dollars) and another 800 for the clutch setup (american dollars).

I dont know of anyone using one stateside, but i am curious on how it would operate and exactly the difference between it and the run of the mill light weight setups are.

GURU Racing has produced a 4140 Chrome Moly Lightweight Flywheel to suit 5.5" clutch assemblies. Lightweight flywheels increase throttle response and aide in overall vehicle performance.

Standard (TurboII)
44 lbs - Clutch assembly and flywheel
27lbs - flywheel

Guru 4140 Flywheel
16 lbs - clutch assembly and flywheel
10.1 lbs - flywheel

So not only providing a performance improvement product but adding a substantial safety factor with approximately 25% less inertia than a 7.25" clutch for improved acceleration.

Applications based on generation 2 & 3 (Series I-VI) turbo RX7's and are a direct bolt in without modification. The kit comes with thrust bearing and housing as well as gearbox thrust bearing support.

Technical Specifications:

Flywheel:

Flywheel currently delivered for the RX7 Turbo case transmissions
RX7 Generation 1-3 (Series I-VI)
Direct fitment within bell-housing with no modifications necessary
No ring gear as teeth directly cut onto flywheel
Flywheel heat treated and black oxidised
Clutch:

Suit AP, Tilton and Quarter Master (QM) 5.5" clutch assemblies
Delivered with custom thrust bearings & mount as well as gearbox thrust bearing slider nose
Material:

All component are precision manufactured
4140 Chrome Moly
Heat treated and black oxidised
