Does anyone know if our valvetrain can handle 8500rpm's reliably? If not, where are the weak points? With the little low end torque that I have in my motor, I wouldn't mind shifting the powerband up from 4000-6000 to say, 5500-8000 =).

Cams are not for everybody. A good cam grind optimizes the power curve where the car will be spending most of it's time. Generally our cams are not used in street driven turbo cars because they are ground to make mid to top end power for a track type application. We have N/A cams for street and track cars though. NOT ALL CAMS NEED our big springs with titanium retainers. ALL NEW CAMS NEED new lifters. Does that mean I will not sell just a cam, no. Many customers buy their own lifters or take the chance of running the old ones.

I'd like to know exactly what you need to do (valvetrain-wise) to go to solid lifters and spin it to 8500. Balanced and knife-edged cranks/lighter rods / lightened flywheels I sure would be key, but is it just a matter of solid lifters and the appropriate cam as far as the valvetrain is concerned?

I understand the bigger issue is oilin' the bearings

I really don't like going solid on 2V cars since in order to adjust them you have to remove the cam housing and mathematically calculate what size shims to use. The cars that we have done were lots of fun to set-up but once 'there' they stayed there. 16V cars with the easy access up top are more user friendly. I have not yet recommended a customer of mine to turn more than 8000 RPM on a 944 based car. Yet those that turn up to 8K don't have problems either with all the oiling mods and other upgrades we do to these. We spin our 914/6 HSR vintage car to 9000 RPM, but it's different. The 'real' issue here is if you have the flow to make power up their. Without at least a 270+ CFM head you are wasting your time at more than 7000 RPM. On a 16V car we are making high 300 CFM numbers! This is where 8000 RPM makes sense. Our own 'Zebra' car is set-up to run up to 8000 RPM and really only make power between 4K and 8K. Our new Boxster (currently a 3.6 ltr) is going to be getting a 3.9 ltr which will turn 9K RPM and make 450 HP or so. RPM is one way to make power if you have the flow numbers to support it. Cams are only one small part of that equation.

C'mon guys give the guy a break, seems pretty obvious he means Vanadium, not like any of us haven't ever misspelled things like Alunimum, Cimmanon, or even Jaygermiester!

I like the face idea!! Were tring to decide what to paint the car since it wil be sitting next to the Zebra car in the pits it will kind of get lost if you know what I mean!! Any other ideas guys? Here is a Zebra pic to work from for those that don't know the car.

Derrek, your Boxster looks sweeeet! You wouldn't happen to have any more pics would you ;-)
I like the tongue idea but I have another one too. What if you painted it like a Huntley Racing sticker! Yellow with big 'Huntley Racing' in your font on it!
