Adventures in PTE/TTE

Post your pics, videos, build info, questions, lap times, smack talk..
I thought I'd start a thread just for NASA PTE/TTE/E3 Miatas. It's becoming a very popular w2w (PTE), enduro (E3) and TT(TTE) class. This is from this weekend at ACS. We couldn't get the new motor into Super in time so we tried to detune Crusher at the last minute, unsuccessfully. We ended up with a very lumpy, spiky powerband that was down 10whp where it mattered. Correspondingly, I got my butt kicked by William (in "Nemo") at ACS where power matters. His dyno plot was the normal smooth, nearly flat NB2 arc from 5200-7200. Mine looked like the rocky mountains with a huge 115whp valley at 7200, ugh. William started on pole both days. I put Hoosiers on Sunday in hopes of keeping up (Nemo on Toyo RR) but it wasn't enough. These two cars are built very similar, dyno classed between 2350~2400#. Next race will be back in Super, the silver NB. Eric and Anthony (in his first race) also had an epic battle for 3rd and 4th both days. Sunday, Eric out qualified Anthony by .001 ! https://www.miataturbo.net/attachmen...ine=1362426552 |

Anthony out qualified Eric by 0.001 seconds. :bigtu: -Anthony |
Anthony, are you going to post your videos here?

Good thread idea. I just got my TTE dyno reclass back, and did the dyno runs over the weekend. In AZ we've got 2-3 Miata regulars in TTE, and a couple other cars, usually enough to hit the 5 cars for the free tires. Unfortunately all of the Miatas are chasing a pretty well-built Integra that seems to have about a second on us.
I'll post up some videos from the last event when I get a chance... so, who's going to be the first one to post some build info? :D |

2390/130 dyno classed Big Grip Kit Xida Club Sport 800/500 RB #54103 front bar 14mm rear bar SuperMiata end links ES bushings alignment 15x9 6UL 205/50/15 SM6 SuperMiata end links DIY "EP" style air dam FM cross flow rad Reroute 5 speed SuperMiata race 7.25" single clutch, ceramic Carbotech 10/8 SuperMiata 2 piece Sport Brake front rotors 1.8 rear brakes SuperMiata brake lines SuperMiata Prop Valve kit Engine by Keegan Engineering FM Wiseco 85mm 11.0:1 pistons High velocity ports Stage 1 integral street cams Supertch light double valve springs SuperMiata shim under bucket lifters ST oversize SS valves Carrillo A beam rods ACL race bearings Square top manifold RB header Skunk2 TB M Tuned fuel rail Toyota COPs MS3pro ECU Racing Beat midpipe and exhaust Clearly that's hardware for more than 130whp. So I detune top end and add more low end torque to make up for the 18.38 lbs/hp I have to run at. That's compared to 16.5 lbs/hp for points classed PTE cars. Nationally competitive PTE should be 3-4s faster than Spec Miata records. William and I both ran high 1:59's at ACS last weekend. I think the spec record is 2:03 there. We heard through the grapevine that a 1.6 SM was dynoed there over the weekend at a torqueless 131whp. Crikey. What are this Integra's lap times compared to the SM records? |

I tired of seeing all these IQ3s too. Where are my wheels? lol

Holy shit.
We're about the same weight, same tires but wider wheels, lots more torques and real suspension. I think the torque, or peak power in the case of a points classed motor, is worth just as much as the shocks. Another thread here a while back, a few mid south and mid atlantic PTE/TTE guys stating they're also 3s under SM records. Similar lbs/hp but way more stuff we can optimizes elsewhere so it shouldn't be a surprise. |

That's without a draft too :)

Good thread. If I get off my ass and cage the car soon, I'll be moving from TTE to PTE this year. Car is nowhere close to optimized for E, but did well enough last year.
Last year's final setup: 1991 Chassis Dyno reclass E* 131hp/2240lb 2001 block 99 head DIYPNP coolant reroute stock 99 header with the interior welds smoothed stock 1.6 exhaust SM bilsteins 700/400 stock bars 13x7.5 Lensos and 185 R6 Cheap, used OPM clutch type LSD Imitation 949 airdam NASCAR COT wing Changes for this year: Cage Open diff to get points back Get someone that knows what they're doing to fix my halfassed tune and get me some more torks RB header and borla SM exhaust Probably switch to 15s and an E no star reclass for PT... 205 NT01 or R6 Probably lose the wing and go to a spoiler for certain tracks Keep saving pennies for some XIDAs |

NASA Time Trial The only miatas thus far that can/have beat his times are miatas with ~145-150 hp but obviously are maxed out TTD/C cars...and are also a turbod 1.6 and a supercharged 1.8.

Unless a miata here is F/I, N/A rarely gets to see 5th gear. So, IMO, all that torque/acceleration would probably own all. I have thought many times a setup like this would wipe [Simon/TTE integra] records, but would absolutely suck at a track like ACS. i have a 4.7 R&P set sitting here too that ive debated whether to toss in for this situation. edit* hmm, just checked my classing sheet, and as my car sits, all i would have to do to make my car TTE eligible is take off the gv-rep lip, go back to stock sways and 1.6 brakes and id be there with 1 point left over, with 130hp and 2220, or 135 with 2225. |
