At 14psi or less the results would be very similar for all blowers as long as they have the same tune.

 

Not necessarily, 12-14psi on the stock Eaton will not produce similar hp as a 2.3KB and with what KB claims the 2.6 should make a bit more. Even a 20hp difference is significant to warrant test results.

 

20hp on a 3000lb car is noticeable but 20hp on a 5000lb truck is certainly not significant and definitely not worth $3000 for a new blower. The 2.6 really shows its colors at 18-26lbs of boost at which point it would be worth the expense in my books anyways.

 

I agree regarding higher boost levels and the 2.6. KB is misleading by stating it works perfectly fine on a 100% stock vehicle, when the 2.3 may be the better choice for those wanting 15 or less psi. In speaking with a KB tech, it was stated the 2.6 would be better at 14-15psi than the 2.3. My concern in speaking with him was the lower boost levels and efficiency. Again it was stated that due to cooler discharge temps the 2.6 is the way to go. KB's test results say otherwise. Either they're leaving something out or would like to sell more 2.6's.

 

Rafa, I never said I'd trade the power for volume, just throwing out the facts, it's quiet.
