Adventures in PTE/TTE

Good luck @ RA
Good luck to everyone competing at Road Atlanta.
In the spirit of this thread, am I right in saying that 99 miata is the best baseline for TTE/PTE? Not trying to steal any setup ideas, but what is the next step - dyno reclass or point mods? Let's assume the goal is fastest lap at Road Atlanta.
FYI, if you are interested I have run fastest of 1:50.8 with my 95 Miata with street tuned MS, bolt on exhaust and air intake, coilovers and bfg r1 tires. I would like to get into Time trials with nasa so any car setup information would be helpful to satiate my curiosity.

NO Point Modification:
3) Radiator upgrade/shrouding/fascia modification (drilled or cut holes/slots) that only provides
increased airflow to the radiator or oil/transmission coolers (without aerodynamic or engine
air intake improvement)
Since I am dyno reclassed the point modification for routing an air filter near an inlet which is +1, is null and void.

I've been through 1.6 point index and 1.8 swap dyno reclass. In retrospect I wish I kept my 1.6 point index so I can move points around by changing modifications to see what works best. My reclass allows only tires, springs, shocks and diff. With 140hp@2425lbs.
With this pte set up I've ran road Atlanta at 1:44.6. This was competing against no one in a NASA SE event.

Must be a change for 2014. I'm 99% sure that the 2013 rules only allowed air filter holes, not cooling holes. Regardless, the additional holes don't make the car faster and they open you up for scrutiny (i.e. you have to prove they don't improve aero, and I could very easily argue that they might/do). I would get rid of them.
Also, what aero dynamic benefit would drilling holes in a front bumper provide? Holes in the rear bumper is a diffuser, but front seems like more resistance by reducing flat surfaces

TTE ran high 1.48-1.50 last time I was there. Obviously, TTE is ripe for the pickins since they are not running particularly competitive times. TTD ran 1.45.x, so there is definitely room to push both groups.
Another thing, TTE guys usually try to fit A6s in their points vs. PT running the R6 or whatever equivalent is available. So keep in mind that your points might be allocated differently than the predominant PT discussion here.
As for nationals, wait a bit and find out .

Nice drive- video shows a winning package IMO- car and driver.

I got 138whp@2390 from Greg which gives me a 5oz advantage!
Based on that it looks like Greg may treat all dyno classed Miatas the same. I figured he would give NBs some extra weight.

RE the discussion about the 2001 chassis not being competitive. Is your dyno classing just really bad or is the penalty to 2001+ dyno classed cars not existent? I know for a points car they have some problems.

Proposed 2015 Tire Rules.
nasaforums.com • View topic - 2015 Proposed Tire Rules (TTB-TTF)
Sticky tires much higher points.
R6, R7, SM7 same as R6 was.
RR now 2 points less.
Could that make a points based TTE Miata on RRs with an aftermarked ECU and a big front bar possible?

Really the issue comes down to the way the rules are written. Heavy cars don't corner as well as light ones, and to correct for the lap time difference, they get a modifier on their class weightower ratio, to allow them more power. While this makes the lap time equal, it makes heavy cars achieve their lap time differently than small cars - in the straight vs in the corner. This also means that heavy cars benefit at tracks with a lot of straight, vise versa at tracks with a lot of corners.
