Impressions Vortech Supercharged:

PROS
  • Acceleration is linear and non-disruptive to fine inputs.
  • Longer straights or sweepers highly benefit from added power.
  • Car no longer struggles pulling out of tight sectors in 2nd gear
  • No one who has driven the car or rode along stated the extra power was negative to drivability.







CONS

  • Added power does not equate to better times
  • Higher class makes car virtually uncompetitive
  • Makes setup more difficult with less people running higher HP.
  • Higher heat, requires more
    care in terms of cool down cycle hood venting and preventing heat soak in IAT and radiator.

Yeaaaa your car is not STX legal at all.

I don't think many will be surprised to see supercharging doesn't make the car much (if at all) faster at an autox. Now you can just drive and not worry about the burden of being competitive.

The most asked question was, "that thing must fly now."
It's completely interesting to see the car before and after.

Before I felt, the car almost stock in RTR/CS or STX was perfect.
But hated it on the track.

After, it's not good enough in autox anymore if you want to compete. Still fun obviously. Have to wait to see how the track experience goes.

That was an interesting review. However, I'd like to see how a well prepped SM twin will do. It'll be costly, but it is the "Spend Money" class.

I think it can be good with the higher class. You are way underprepped for the class that the supercharger puts you in. Plus on street tires. The bumped class allows for a lot of weight reductions a lot more tire and rim width, bigger brakes ect. Until the car is prepped 100 percent to the rules its hard to say if it will be competitive or not.

I agree. Hopefully, someone will try one day.

I don't think most people would find the value in turning this car into a stripped down SM car for autox until you can buy one for 10k.

Awesome review!

Toss some Hoosiers on it and try again.
Also, I think your review closes the door on the platform for SM class prior to fully exploring the key allowable "other than power" mods (Tires, Wheels, Gearing, Suspension, Aero, Diff).

By far the key limiting factor here is definitely grip. Some areas it's terminal understeer, some it's overseer.
@TimR
After getting settled with the car other than smoothing out a few areas I don't think there was a lot of time to be found.
Getting the car to trailbrake was also much more difficult than other cars I have driven.

Throwing power at it was not the answer by any stretch.
