Adventures in PTE/TTE
#261
PTC/E1 dyno classed for 170whp. 2.0L, 11.0:1, ported head, square top and I think, pump gas (not sure).
PTE/TTE dyno classed for 130whp. I cleaned this one up later but can't find the plot. It was pretty smooth and made 130whp from 4500-8500rpm with a 5psd and 4.875 OS Giken. Ran most courses in one gear except for the odd hairpin.
Edit. This was an 85.5mm, 11.0:1 (2.0L) with the final hand ported prototype of what was digitized for our CNC head.
PTE/TTE points classed for 144whp. This is the car we didn't take to Miller and I regret it.

Except we used 4-5-6 so 5 and 6 were right next to each other. The points build yields a good powerband but not dead flat like a dyno classed.

Wow, do you guys really have to share everything . . . with everyone?
We're going to run my points classed 99 in WERC E3 this year. I might run some TTE in it as well while I'm out there. I still can't afford tires so it would have been nice to have some of the other secrets still in the bag. Oh well, I'm still to slow to win anyway.

It's nice to see that you got the job done in E without aero. I don't have any extra points for it and I've been concerned about the front of my car at track like Road Atlanta. Every damn TT miata I've seen in the south-east has the big front air-dam. Granted, the rules have changed since you ran in E.

Meaning the SM7 and R7 are different from each other? I'll be super sad if I can't run SM7 take-offs "competitively" this year while I get seat time and sort my TTE points car out. Guess I could win some races to win sticker R7s

How to win in PTE:
1. Make your car as heavy as you possibly can without ballast, then add 200lbs of steel plate
2. Buy the best single-adjustable (or DA without remote canister) shocks and springs you can afford, and set them up to work with stock sways and endlinks
3. Run 205/50 Hoosier R7s on 9" wheels
4. Spend the rest of your points on power, until you reach your power cap, then add torque
4a. Dyno class cars, request PTE* base classing and use the +7 to add power and hope that nobody in your region was smart enough to start with an NB1 in the first place
5. Read the zero-point mods section, and do them all. Then read it again and do some more of them
You are doing it wrong if:
-you take points for aero
-your car weighs less than 2400lbs (2500lbs? 2600lbs?)
-you can points-class your car and you are dyno-classed
-you are using a 1.6 (go build a competitive PTF car)

Thanks for the tips! I'll definitely be adding ballast most likely. My 99 is around 2120lbs with a plash of gas in its current STR trim. Add some weight from safety equipment, myself (200), more fuel, and I I'll just barely make the 2400lb minimum.
Has anyone confirmed a speed or longevity difference between the sm7 and r7?

I am picking up an NB1 tomorrow.
Plan A is to keep it around as a Leave-It-Stock car that the wife is comfortable driving during nice weather, while I make the NA a more serious thing(0pt mods and such)
Plan B is to part out my NA and make a newer/nicer, double duty, street/TT car with all the new stuff ive learned the last 7 years with the NA.
Assuming plan B, what major changes, if any, would you make to "the formula" for a TT specific build?
It will be heavy because stereo, cruise control and AC will remain.
It will be easy to points class because it is 99% stock right now and it has no appearance package stuff on it.
I already have a rollbar, Xidas, 9" 6uls, a pile of sm6s and an available 6 speed...

I don't think it would be worth the points to run a 6-speed, but I don't have any first hand experience.

So my plan is to go forced induction and get a dyno reclass. I am planning on about 135rwhp and 2850lbs for TTE and 150rwhp and the same weight for TTD.
I bought the car new and like it, so I simply accept that I won't be competitive enough to go to nationals.
#276
I have found it's impossible to be competitive in TTE in our region with any extra weight, A/C, PS, interior, windows, door cards, etc.
There's enough other TT Miatas and Hondas that are completely prep'ed along with the PTEs and SMs running in TTE, that running anything except a car at the limits of the rules (weight, power & handling) has no chance to win any tires or brake pads.
We had 12 TTE entries in our Jan event. I just pulled the windows, door cards, radio, glove box, etc, 45lbs worth. Now if I can just get 45 lbs out of the drivers seat.

You had to drop 45lbs to get close to the 2400lb min? My car is 2120lbs as is in STR trim, add a roll-bar(50#) and myself(200#) then I'm almost to the min. I may have to run some ballast or run a full tank of gas to make the weight, lol.
A big field like that would be fun! The first event with SE at CMP had 7 cars in TTE, with quite a time spread. I'm anxious to get going with NASA this season.

Daaang. I searched everywhere for this tire last winter but couldn't find any way to buy it. Looks like it's finally available. Could be the perfect miata tire for TTE or maybe even PTE thanks to the 195 sizing. Now I'm kinda wishing I'd stayed in E for one more year before buying flares and 245 Maxxis...
Ratings, reviews and specifications for Hankook Ventus TD Z221 Soft tires
1 star reclass +7
195 TD -3
shocks/springs +5
OS Giken +3
air dam +3
wing/nascar spoiler +4
=19
Or swap the air dam and wing out for a 2 star reclass if you can talk Greg into it. He wouldn't give a miata a 2 star reclass last I heard.
