- Turbo Dynamics Stage 6 power package for the 998 turbo sleds
Turbo Dynamics Stage 6 power package compatible 2017-2019+ 998 turbo snowmobiles (SRX ZR9000, Sidewinder, Thundercat)
Huge power increase. Make power at lower boost level, Insane throttle response, more power on pump gas before getting knock (320HP+ 91 octane)
Our testing shows unsurpassed Power on pump gas and more power on race fuel as well.
You want the ultimate stock turbo sled, trail or race or both this is it !!
This kit also improves reliability at high RPM with stiffer than stock springs allowing 10500rpm without valve float.
With the TD stage 6 the rev limiter is at 10 000rpm.
Minimum requirements to buy the TD stage 6:
Own a TD flasher, a TD wideband module, Header, High flow intercooler, Manual timing chain tensioner, TD fuel pump upgrade, TD fuel regulator
The TD header is extremely high flow, fits the stock heat shield and clears the gas tank by a safe margin. The header also provides more power at lower boost, lowers EGTs
And more power on pump gas. We also were surprised to see a boost on race fuel with the latest race sled we built.
The TD super cooler and intake provides cooler air temps and more airflow for increased power and sustained power. As well as safer intake temps for more power on pump gas and race fuel.
This kit comes with ARP head studs to increased clamping on the motor. The 998 motor can handle a lot of power, but it's main weakness is the stock head bolts at about 350HP we see the limit on the stock head bolts. This extra clamping raises that limit.
The HD timing chain is an option if you have engine our of the sled. We are currently running ours without it, as the stock chain has been good so far. For those doing very high miles at high power this will be a good option to add.
