Thats my plan! I had a complete motor rebuild from the dealership 8,000 miles ago so its broken in and ready. I want to start working on something. Speed Force racing supercharger or an STS turbo system are in my sight.

I was watching Supercars Exposed and they had a Carrera 10 I think they said it was 650 HP, could not hit 200 in the Texas standing mile, I think it hit high 190's. So it looks like you need more than 600 to hit 194 in a mile?

HP is important but not everything. Power to weight, aerodynamics, gearing etc.
My 1 ton crew cab is 500+hp and can't do more than 90 ever. My 180hp R1 would probably hit the 200 mark with slightly taller gearing.

I wanted to ask you all a question off topic.
I've talked on a couple of threads about how dangerous wheel spacers are and how I am against using them. Coming from a mechanical engineering background, and having hung around stock car racers in my youth has made me this way.
But in the Porsche community, there seems to be a very cavalier attitude about running them.
The additional loading on wheel studs and bearings that some types of wheel spacers introduce comes on in mere microbursts of time, and this is where i believe the danger lies.
I come from an area that gets bone chilling cold and this makes spacers even more dangerous.
Am I being to **** about them ? Any thoughts ?

i think it is more of an issue on more mass produced cars where some strength and quality is sacrificed for cost. things on the porsches are overengineered in many cases, the suspension pieces, when kept up, are pretty stout. as long as you have a quality wheel on there it shouldnt be an issue unless you really are using a huge spacer

My mechanics have always erred on the side of caution when spacers are concerned, especially on the front.

..and I've heard from a reliable source and totally insane bike rider that the Carrera GT feels like no car he's ever been in. He had quite a nice (not excessively tuned 944t at the time) and I can assure you he knows how to drive it. He described his standing mile as a passenger in the Carrera GT as the only car that gave him the same rush as his bike (Aprilia RSV) just from the shear acceleration! Makes me want a ride in one! Badly!

The fastest 951 Cup cars were clocked at 300kph (~186mph) on the Hunaudières straight at Le Mans in 1990 - in those days there wasn't the two chicanes - and they developed a mere 305hp.
If the idea of exceeding 7k rpm (let alone 6k) didn't bother me I think I could break 190mph now that my car is 3.0'ed, as the speed at which it builds revs between 4k and 6k is nearly as relentless in 5th gear as it is in 4th gear.
My point is we don't really need big hp on a 944/951 to reach very high speeds. Or should I say Euro hp

I have always preferred to run without spacers but in some applications it just seems to be the easy choice. Had to run them on some race cars and on Jeeps from time to time.
Here is some food for thought.
A spacer really should not produce any more force than a wheel with the same offest/backspacing would. Once they get to a certain thickness they usually bolt on to the hub and then the wheel bolts to the spacer.
Many in the off road world run spacers without issue. I bring this up because the forces they see can be much greater. Tires that are upwards of 40" tall, weighing 150+ lbs each. With the torque multiplication of super low transfer cases. Then being bounced, bumped smashed and crashed into rocks from all sorts of angles. I have seen very large 1 ton axles break before a spacer fails.
Here is a picture of a 1.5" spacer on a Jeep JK that runs 35 and 37" tires on beadlocks.

A bad idea under the best circumstances, but when applied to race cars and extreme loads/speeds it is borderline negligent in my book.
