It should also improve mileage if gearing is corrected.QR10 is a resistance decade box with modern UI and communication port. I am looking for 350+ NA simple reliable hp and tq. Turbo and get 500hp is pretty easy, but I don’t want that complexity. ![]() I will be researching further, and have made many contacts, hopefully it can be a help to us all. Are only affordable by those with F1 budgets. ![]() I have deep pockets, but not that deep as I have done a bunch of research, and “true”custom cams etc. For example why is nobody improving on header or intake design for this engine? Mostly because there is not enough interest, And it is easier just to boost it. Remember that theory and tech has advanced a long way since 1997. There is lots to be gained by Good, or better, design of cams, exhaust and intake. So far the simulator puts peak torque at around 4,000 no matter what I plug in, that is very close to stock. I want a daily driver so high idle vacuum, longevity, and power below 5,000 are the goals. I can adjust the power band by cam timing and other means. I have a pretty good simulator software, and even with mild cam etc I expect torque to be over 400, and at roughly the same rpm as stock. As it will be stroked to 5.5 L it will have inherent torque so I can do some things to increase power in the mid band,that may affect the low, but with the extra torque it would still be a low end daily driver. I will comment on each separately.įirst let me say that my engine will be a bit different. My application will be different than others as I am stroking to 5.4L and keeping revs below 5,500.Īll very interesting comments, opinions and advice. Easy to achieve high flows, harder to maintain the velocity. For my application I need velocities around 240 ft/sec, and max flows of over 300 at 0.450. One issue I would have is how to make sure no shops kept the programming to use without paying.Īnyone out there have a proven (dyno) head with flow that is useable, (in other words, not just big flow but the correct velocities for broad band power as bigger does not necessarily mean better unless you are spinning to the moon). The only way I can think of is to get a hand ported head that has proven to achieve a desired goal and then use it as a template for the CNC programming.Īnyone interested? Or if I could find and borrow the already proven, head and pay for the programming, would anyone be willing to pay a usage fee to have their heads ported? It would still be cheaper than hand port, any way more consistent. The fly in the ointment is that we would need to know exactly what we want to achieve. Once done CNC porting is faster and cheaper. If we had enough people wanting it sure would be good for us to own the program. Problem is CNC needs to be programed which would cost about $3,000. ![]() I have looked into CNC porting which would be the best as it makes each port identical and leaves the best finish (basically whatever finish you want such as golf ball etc.), (somewhat grooved and rough for turbulence). I have been using a computer engine simulator to test different flows and velocities and see there are great gains to be had. I know that a number of you have ported, and had ported, heads.
