DPT 901-TM

78.5g-87.8g (higher gram range for extra modified versions)

The 901-TM Pro Tuner kit is a fully adjustable weight kit for the 900 ACE Turbo with pDrive primary clutch.

Designed as a high quality billet steel flyweight set to help satisfy the demand from performance shops, racers, and those clutch tuners who modify the ECU programming and add even more extra Horsepower and need extra weight added to the flyweights. The 901-TM  kit is designed to allow the use of more weight than the standard 901-T kit that most use with flashed ECU.

The regular 901-T kit is most often used for all modified tunes up to and including the 205-210 HP tunes ( the most common ones)...not this 901-TM.

Some have asked for a heavier base weight for tunes that use bigger injectors, added fuel pressures, bigger turbos, etc. This 901-TM was designed as a heavier version for those type of mods to test with.

Same design as the 901-T, just heavier for testing by the applications described.

There are two threaded passages to allow adjustment of mass to the inbound or tip position. The inbound weight or”heel” position uses Dalton’s popular “Quick Adjust” method, that allows you to fine tune the grams without even removing the flyweight from the clutch. There is also a threaded tip weight adjustment that allows you to adjust the “zone” of the grams needed, and the amount of tip weight required for the application.

There are many combinations of added fasteners that will allow fine adjustments of “total grams”, as well as placement locations. Many combinations of less than one gram increments can be done in different configurations of weight placement.

The Dalton 900-T/901-T/901-TM  Series flyweights are designed as a complete drop in assembly. These are the only sets we have designed and offer as proper fitment for the 900 ACE pDrive clutches. The weights are the proper length, width and dimensions to fit properly in the clutch. They have a close tolerance high quality bushing, and there are no additional hardware, clickers, or spacers required. You simply bolt them in like stock weights.

This set is for more modified vehicles. 

As the name suggests, this Pro Tuner Kit was designed to help satisfy requests from clutch kit companies, pro racers, and performance shops who want to tune their own clutching to suit their own needs and/or performance levels.
