Craig, I do not have the numbers to compare restricted car to non restricted car, and I agree that I don not expect the cost increase to be very significant, but I do believe you will notice it. In terms of HP only, my understanding is that non restricted 99's will make around 13-15HP more and VVT's around 9-10HP more than there current restricted versions.

 

Trust me, I too like to go faster and for that I have now run my STL program for 3-1/2 years. On average I am going 5% faster in my STL car compared to my SM car in terms of lap times (4.5% for tracks with only one 5th gear straight and 5.5% faster for tracks with more than one 5th gear straight). For me this pleasure of running 5% faster has increased my costs by approx 2.5 times the cost of running SM. 

 

I guess the mathematicians and engineers can extrapolate from this curve, and figure out the cost increase. But I have never seen tires or brake pads last longer when accelerating faster or decelerating quicker. And I suspect engine costs will also go up as the rush to find the heads and headers and intake manifolds that flow better will require more time on the dyno.

 

And sorry about the "Claude" - too much wine at lunch for me! Was channeling my inner Inspector Clouseau!

 

I'm with Claude on this one..  :)

The only real opposition is the NA cars and the cost of flowing manifolds etc that I will be the first to admit I do not bother doing with the plates. I think the plates are keeping some builders close where is we opened it up, I think you would see a few builders clearly out perform the others. Further upsetting the apple cart. Could be done, but it make be some growing pains that we dont need.

Both VERY valid points, these points alone having me reconsidering

 

As far as your Stl comparison,  That is completely unrelated to that topic. Your Stl car is like most a ticking time bomb and wound to the edge.  Sm is basically a production car with no engine mods allowed.   Also, few throw new tires at a race to set track records in a race they will win by 2 minutes :)

thank you for these hard numbers. 

i knew STL was expensive, but wowsa!!!

ill stay in SM, and if SM drops NAs, i guess that puts me out.

Only costs that much if you want to run at the front (and choose to do it with a Mazda - suspect doing it with a Honda might be slightly cheaper). You can run STL in the kill zone in your NA SM any day of the week, but as you are no doubt aware, mixed class racing comes with some caveats.

Cal,

 

Thanks for the response.  I especially liked the description of driving ability.  Everything but "sometimes front mid pack" fit me pretty well, especially "well maybe not mid pack".  It sounds like the laptime improvement is probably in the range of 1 sec for an "average" track.  That would be a little helpful in enduros, but doesn't seem worth spending a bunch of money to upgrade to NB.  I might be able to get that much improvement switching from my Rx7 to my SM-1.6.  I have been planning on doing a comparison between the two and will have to speed that process up.     

 

Cheers,

 

Carl
