i am no turbo expert but i will say that the hx35 is out of it range after 32-35 lbs boost in other words all it is doing is pumping superheated air into the engine. the b1 runs a larger housing so with the same amount of fuel it will not boost as high. the 40lb put out by the b1 is cool air and well within the range of the b1. i will say that with this turbo alone you can make alot of hp you only hold back is you 180hp pump if you have the 215 you would see at least 50hp more and with piers stupid pump 75hp or more. your hold back now is not air only fuel. i am no expert and i maybe wrong but that is my 2cents. i know that guys have made 450-475hp with the stock hx35 but i imagine they had the 215 pump and lots of smoke.

How do you figure that at the same boost pressure with a B-1 vs. a HX-35, the 35 is pumping hot air into the intake vs. the B-1 pumping cooler air? The velocity of the air entering the engine should not create heat, so explain this to me, please.

From what I understand, it's all about the amount of flow each produces. B1 has a much higher CFM rating vs an HX35. So in order for the HX35 to fill the intake with compressed air it has to work harder thus heating the air. It's like trying to fill an 80 gallon air compressor tank with a small single stage pump vs a huge twin pump. Compressing air creates some heat...

vss,



ditto



hx35 has to spin alot faster to produce same air flow as the b1. the b1 has more spinning mass so it spools slower but at the same time pushing more air.

My converter is in the 1400-1500 stall range and with 3. 55's I can make a street look like a coal train went through on a hot day. Now understand that I don't intentionally drive like that all the time.
