Andy,
I'm wondering what the results will be myself! The Mast does see a better improvement on the intake than the exhaust for sure even though both improve going off flow numbers alone. I deliberated a lot over getting the Mast vs porting the stock LSA heads and in the end 2 reasons made me lean toward the Mast. First, I can stick my stock heads on the shelf and have something to go back to if I don't like the way this turns out. And 2nd, part of my goal is not to spin the blower too hard because even though a better heat exchanger can cool IAT2s better, the blower bearings still experience the increased heat and stress when you spin it fast so I'm going with the logic of removing as much restriction to airflow as possible from the CAI, through the throttle body, blower and into the combustion chamber to allow that blower to be as effective at lower speeds as possible. Then obviously I've done what I can with the exhaust side (custom cam, headers) with the exception of full open exhaust. I might experiment with with different header sizes, full 3" exhaust, etc later but out of the gate I'm going 1 7/8", high flow cats, and stock the rest of the way back. It's all theory but I'm hoping to preserve a little life out of the blower by not driving it too hard but still get good gains in rwhp. 700HP with great torque everywhere will make me happy... BTW- Can you educate me on how your Fuel pump for the ZL1 differs from stock? I haven't solved all of my fuel needs yet... |

What are your thoughts on a splayed-valve? Big blocks ran these, and seems more like it would be more in line of what valve angle fits that particular valve alignment. Thanks Andy - it's all very interesting Quote:
I'm sorry - just split-balling and can't wait to see what you come out with. I'm really looking forward to seeing the blower, because the snout looks OUTSTANDING!!! OMG!!! Are there any identification marks or machining on the outside of the heads, like below the exhaust ports or on the front or rear? Like I mentioned - I need stealth Thanks for all your comments

The Mast heads would not be stealth. They're 3/4" taller and say MAST on the front. And for a little over 600rwhp, I think Mast heads would be wasting your money honestly. You might be able to do 600rwhp leaving the heads and cam stock if you do all the other bolt-ons (both pulleys, CAI, headers, injectors) and port the blower. But to stay stealth on the outside (stock air intake) you'll probably need to do 'something' to help make up for what the stock air intake is restricting.

Our pump is a drop in unit that utilizes 2 OEM quality pumps, and a bucket designed for those pumps as opposed to an aftermarket creation. We design and manufacture it to be a true drop in solution needing no wiring changes, module, or line changes. It is the same pump we used in ours to run 9's in it.

So are they just a pair of pumps that flow more than the stock ZL1 pumps? Cause the ZL1 assembly from.the factory is a dual pump setup unless I'm mistaken.
Thanks! |

Actually, that was a big blunder mis-print in the GMPP catalog. The ZL1 pump is just a single pump.

man radz28 i need to pick you're brain at the C5Fest. It seems You're having the same stuff in mind as i do. I keep reading all those threads in the ZL1 section and wonder "how did they do it?" or "i need that, where do i go?" and sure enough i keep reading and Radz28 asks all my questions... It's almost scary how much we think alike! P.S. i'll be taking my ZL1 to Switzerland by the end of the year and i too need a stealthy package ! Right now i'm flirting with an ADM HP650+ package with a twist (maybe add an LS9 cam and some ported goodies). how about that? Unfortunately it also needs to be within a reasonable buget lol |

Yeah - I full of questions There are so many options, and I'm the type that likes to maximize a combination before really getting crazy. I don't like spending money on replacing parts twice, so believe me that I'm taking notes on everyone sharing their builds. I'm all ears (eyes) Post your build so I can track and learn

Man....so do I, outstanding workmanship and volumetric increases. That's motorhead eye candy. Keep those shots coming as you progress if you could. Thanks!
