I called PC tech again yesterday and was asking about the difference in pulleys etc, it appears that by my serial # mine is setup for 7 psi @ 7k rpm not the 7psi @ 6500 rpm like I ordered. So @ 6500 rpm they said I will be closer to 5-6 psi. I’m just gonna listen to my tuner and go from there. He says it’s gonna be close but will be able to run e60-70 NP at all. As for rwhp we shall see, I’m thinking it would do close to 600 whp on either 93 or e60 ish. I was trying to avoid blending but like King and a few others have said there’s not much benefit after the e60 point. Looking fwd to see where it ends up and to feel the power difference with the P1-X 😎 |

Oh boy! Good to know. I don’t understand how all these can be setup different? Does it have to do with the head unit itself? If PC tech is saying 7psi @ 7k I’d like to value that as 100% true info. Now Idk if I should just buy a 4.13” pulley or not. PC says I’m not gonna see 7psi until 7k rpm….ugh!!!!

They may be taking into account any bolt ons you may have installed.
I would think that, for example, a freer-flowing exhaust is going to lower intake manifold psi for a given pulley. So with my stock cats installed and 4.13 pulley, it makes 9.5 psi at 6800. Maybe if I changed the intake manifold, and installed long tubes, i'd get lower intake psi with that pulley. The system might "back up" in the intake. Kinda like sticking your hand over the end of your leaf blower. It's going to build more psi due to the restriction?

CJ how do you like the car with the PC? Quite a difference I’d imagine? |

Lets break it down to What you need to make power.
Air and fuel. Air you can expect about 10 Hp per 1 lb. of Air, for example 50 lbs of air per minute makes 500 HP So Keep in mind if you try and run low boost you will never make any real power. Fuel, Fuel quantity is based on 2 things Type of fuel, and Air flow. With a given amount of air on gasoline, you need 1 lb. of fuel for every 12 lbs. of air at Full power. On Ethanol the Amount will vary based on Ethanol content so about 1 lb of fuel for every 7 lbs of air for example The more ethanol the more fuel you will need on that Same Amount of Air. Can you make more power on Ethanol fuel vs gasoline? Absolutely but the gains are only about 10% from pump to E85 So I don't agree with trying to run lower boost just so you can run more Ethanol. Set the boost level at what it will tolerate on pump gas tuned well. Then blend Ethanol until you get to about 90% of your fuel system capacity, You have to leave room. You will see good gains up to about E-60 then they will taper off toward E85.

Very good info Ted. I guess I will leave the setup the way it is and once tuned on 93 we should have a better idea. Worst case I swap pulley and get it re tuned on 93, then start adding e85.
Any idea of the fuel system limits on 93 with LT4 fuel stuff with dsx aux? Thanks |

Here is a couple vids. 1st vid is a Heads Cam converter 4th gen on a 180shot, the P1x 6th gen, and My Whipple 6th gen. I gave the hit to both cars. Second run is 4th gen vs my 6th gen hitting at the same time. Both 6th gens are similar boost. I make like a half pound more peak but quite a bit more under the curve. I am on E40 he is on 93. All 3 cars tuned by me. 4th gen trans doesn't like the Nitrous through the shift. Just posting this for comparison on how much difference giving up the hit makes. Either way I suggest doing what it takes to continue running E or a blend of because 93 and boost is leaving a lot on the table. https://youtu.be/tG1dVSYPTiQ https://youtu.be/FOG6LeYwju4
