At least in XP.

A fantasy of mine is to keep my car all Porsche and put in a 993 3.6. While the car would be +/-100 pounds heaver it would have over 300hp (with Varioram) and around 250lbs of torque. It would be a great hill climb car able to compete with the big bore modified cars.

OK, but then what do you do the rest of the year? XP rules would dictate ballasting up to 1997#. Are you kidding me?

So the only way to be competitive in XP is to convert to a Suby or shove in a twin turbo motor, just like everyone else.

Annoying.

No Nitrous. It's considered an Oxygen bearing additive, which is (to my recollection) not allowed.

Plus, why in the wide wide world of sports would you want such a peaky spike of power? That'd be worse than the proverbial mule kick the old 935's gave in mid turn when the pinwheel finally kicked in...

My thought was a cheap $500 investment that could easily be recouped in which to determine if that extra 50 hp was really worth it to him regarding lowered lap times.

If it really translated to an improved lap time that was substantial then he could justify the investment for more power.

Never thought of using it permanently, I know its peaky, He could put a tiny stiff spring at the end of the throttle pedal right before the full throttle switch so that he can feel the difference and know when he is going to hit nitrous. 95% throttle on an NA car is pretty much the same as 100%, Therefore he could be coming out of a corner that he knows doesnt need the nitrous and just give it that 95%.


My audi allroad has a similar thing from the factory. 95% throttle and its plenty of power for most of my activities. But when I really really need that something extra I push the pedal down even harder past the first stop and it automatically downshifts to optimum gear and gives me a couple extra PSI for a substantial increase in forward thrust.
