"quite a bit" is definitely a relative term, but still significant in this case. Exducer base on stock atmospheric turbo by my calipers is 88.2 mm. it tapers out to 92.2 toward the cover as maximum exducer tip measurement leaving the average tip measurement of 90.2 mm. Some may argue the 92.2 measurement is the basis showing only about 2 mm larger on the Elite unit, but the most important part is where it measures at the base against the backing plate, which is 88.2. Elite Tow-Power atmospheric turbo measures 94 mm across the entire exducer tip giving minimum 1.8 mm, maximum 5.8 mm difference averaging 3.8 mm increase. The compressor housing backing plate is also machined out @ 6 mm to allow the larger compressor wheel to fit.
