I've run 2 weekends at VIR, got tagged for compliance on one of them. The mobile dyno that NASA-MA is using was ~1.4whp off from the one that I went to to get the car tuned. Not sure if any Miatas got popped for compliance on the 2nd weekend. I didn't hear anyone complaining about the dyno though.

 

I am sure NASA is trying to work out the dyno issue. I can't imagine an organization won't listen to its customers on something as significant and ego-related as this.

 

Nah they'll do their best to sweep it under the rug and continue with business as usual. This is nothing new.

 

FatKao, You got popped over 1 or 2 hp? Dude, you need to leave more of a margin than that... lol

 

I think he was saying that the difference was 1-2 hp between the compliance dyno at the track versus where he tuned it back home.

 

Yeah. I was like 10whp under at that point. I have heard rumors that there will be 2 dynos at east coast nationals. The one we used for the last two races and someone else.

 

I'm moving to TTE. Wasn't expecting the 245 base tire size, but I'm happy to see that.

Your '96 Mazda Miata with a 1.8L VVT Miata 1.8L motor swap and a maximum 141 rwhp on a Dynojet, and a Minimum Competition Weight (w/driver) of 2455 lbs, will have a new PT/TT base class of PTE*/TTE* (seven points). Your new base tire size is 245mm. You will not assess modification points for Section B. Weight Reduction or Section C. Engine Mods. You may update to '01-'05 Mazda Miata brakes without a points assessment as well. However, all other modifications, including transmission and LSD, that are not standard items on a base trim '96 Mazda Miata must be assessed points. You must be compliant with the above listed maximum Dynojet HP and Minimum Competition Weight during any tech. inspection.

This option may only be used with a PTE/TTE or higher Final Competition Class.

 

It's probably a typo, he's given me reclasses with typos like that in it before...

 

Yeah, you should ask for clarification. I've never heard of him allowing that.

 

Is the sport brake allowance for a TTE car typical?

 

I have seen reclasses where he has written in for the 1.6l chassis being able to use the 94-97 brakes without taking the +2 points for them. I haven't seen enough of those reclasses to figure out if he decides to give you a slightly worse power to weight reclass as a penalty for it though.

 

VVT reclasses get a 15lb penalty but get sport brakes for free.

 

I emailed asking for a clarification. Last thing I want is to be DQ'd.

 

Yeah, I can just see that now.

"Here is my dyno sheet and email from Greg."

"Oh, sorry, that was a typo on my part. DQ'd".

"Thanks for nothing."

 

I've never heard of getting a new base tire size out of class. I can see it being an issue with my competition, and, I think, understandably so (it would give me enough points back to run front aero). I can't find anywhere in the rules that the base tire size can change from what the class tire sizes list.

 

Looking forward to a dyno reclass. Let's say for tte its 2400lbs and 130whp. Lets say I make 120whp. Am I allowed to weigh 2300 (or whatever the actual equation would be?

 

Greg's E-mail should give you a range of power/weight to choose from. Mine had 3 combinations I could use.

 

No, you must meet the minimum weight on the reclass form regardless of your power level

 

If one were to have three points left over, is that best spent on a limited slip or front air dam?

 

If you don't already have a Torsen, then an OS Giken. If you do already have a Torsen but don't have an engine that makes within 5whp of peak power over a 3000rpm powerband, then a 6 speed.
