TJM01 said:Jay is correct. Series II is a roots style where the IV is a twins screw.
Roots vs. twinscrew has been discussed about 90 billion times. If you do a search, you are going to find a wealth of information.
Both setups use the same intake and intercooler.
Both setups use 30# injectors
The series IV uses an aluminum intake tube (tb) while the Series II uses a plastic one.
Both have heat exchangers and a water pump.
Both styles are pretty much bullet proof and will give long life.
BTW - You need to change oil on the series IV where the II is self contained.
Power output is low on both of them due to intake and intercooler design. It can be fixed but requires some cash to do it.

TJM01 said:There is no series VI - are you talking about the IV or V.
The KB from what I've seen is a better designed unit and has more potential.

Tjm01, I have the series II and Saleen reccomends the oil in the S/C be changed every 15,000 miles and that's what I do. Am I doing some thing wrong?

Saleen Tech Rep said the Series IV lube should be checked every 4K miles and changed out every 50K miles.

The main difference between the two in on the intake design. The KB design is more efficient by far and the numbers can show it.Kcsburk said:How does the KB and the series VI stack up against each other? What kind of HP can be expected out of a series VI?
