We have an excellent track record with our TH350’s. Deep into the 10’s without failure, they have proven to be a very tough unit for a reasonable price. We feel they are a very good choice in cars up to 600 HP/TQ but capable of up to 800 HP/TQ especially in lighter cars. The limiting factor is the stock planetaries. There are aftermarket planets available to make them live at even higher power levels but we usually recommend a TH400 for a dedicated 600+ HP application. Our goal is to provide long term reliabilty. Our base model TH350 has lived at over 600 HP reliably.
