Default What NASA class are you leaning towards for 2016?

With Rx7's and turbos my choices are endless. I am seriously looking at ST3 or ST2.

Who else is joining one of these?

And if not, what are you driving and where are you thinking about for classes.

My car starts out as PTE and looks like it will be PTD as it sits now.

I figure a lot of IT and STU cars will end up in PTC though when they tally up every mod they actually have, so i'll probably do some more mods to bump myself to that class.

I'll be ST3 and still overweight (the car, not me). I've got to find some more power or more chunks of weight to remove.

Maybe we should include our calculations for a bit more clarity on how we are getting to the numbers:

Adjusted Weight/Horsepower: 10.108


Weight: 2550
Power: 245
ST3 non-stock aero: -0.4
DOT tires 250-275: +0.3

Calculator:

st3 (can't figure out the pt rules, esp w/ an engine swap) ...

-.3 roof line (boxster w/ non-oem hardtop)
-.4 aero (aftermarket front bumper cover and side skirts. and a big wing on the back would look cool)
+.3 tires (DOT 250 to 275)
-.1 weight
------------
9.5 modified w/hp

OR

-.7 non-production
+.3 tires (DOT 250 to 275)
-.1 weight
------------
9.5 modified w/hp

same same.

expect around 300 hp at the wheels (engine swap)
gives 2850 lbs w/ driver
or 2650 lbs for the car (about right for a stripped boxster w/ cage)

all in all it seems a good fit for the car (the driver on the other hand ...). just have to finish the slow (slow) build process. and cross my fingers and hope that sean goes into st2.

In your case PT rules are not an issue, as you are below the break out Lb/HP for PTB (10.5Lb/HP)
PT adj power to weight 2850/300=9.5
9.5
+0.4 250-275 dot tires
-0.4 weight
=9.5lb/HP

I agree with the Pt rule confusing.

St3 rx7.

Non factory aero. 0.4-
2600-3000lb. 0.1-
Dot 240-275. 0.3+
Rotary/no tq eng. 0.3+

Total. 8.9

Should allow 292hp @2600lbs.

Exact weight/hp to be determined.

My approach for anyone that as requires (or is considering) a new Base class in PT
(this is required for engine swaps, aftermarket forced induction, an upgraded or modified turbocharger/ supercharger, increased number of camshafts, non-OEM heads, or a ported rotary engine)

Would be
Step one... do the PT Adjust power to weight math
If you are under 10.5... you are in ST
If not is you are really close to 10.5 (but above) and have a lot of suspension, aero, driveline mods.. you are like in ST
If you are not close to 10.5, or have limited other mods. go to step.

Step two... Submit a dyno, with your weight (w/ drive) or a dyno with a desired base class. (where to submit will be out very shortly)
The WCMA (with NASA) will provide you a new base class

Step three... With your new base class start adding up your Points assessed for your modifications.
