Found this while I was looking for pics of the cooling system, specifically the coolant lines that run to the throttle body.

Great pics and comments of the innards of our engine.

thats cool...didn't know thats how the HPFP worked...

Wow, amazing read and photos!

What I gathered from the cams part is that while aftermarket cams may not help with making power as much, altering the lobe for the HPFP may help get more oil flow into the motor if the pump can handle it.

I read somewhere that the HPFP cam had two lobes, and that a 4 lobe cam could be made to increase the pressure/volume.

Also, I think you meant to say more fuel, not oil. HPFP pumps fuel.

Great post! Thanks.

Nice find. There are a lot of links to other stuff in there as well. I also read their article on the seam weld work.

Lonewolf · 03-29-2014, 12:18 PM

Great post...lots of useful pics in there!

For me it was really interesting that the cam was aggressive enough that they thought they might not need cams at any point.

Really interesting article as well. I wonder what the cost is to get your car seam welded if you do all of the prep?

One item caught my eye:

Quote:

The small lower oil pan also acts as a funnel since the pickup point is very precise. Encountering g-forces commonly found on race tracks will begin to cause issues with this design. A larger oil pan with baffling will allow you to not worry as much about waiting for the oil to drain from the heads while pulling some serious g’s.
