Guys, I'm not sure where else to go with this. I've posted on the NASA forum, our local autox forum, and no one can give me a straight up answer.

I'd like some help with classing my 2003 Evo VIII.

Here locally, they throw all the NX- R/U/S into one class. However, I'd like to know if I'm in R, U or S or possibly just A, just in case I attend an NASA event somewhere else this year.

Here are my mods: I tried listing the additional points. Please correct anything that is wrong to help me figure this out once and for all!



Here are my mods this year that will add points from what I see:
Lancer Evo VIII ('03-'05)(AWD) NXC** 3263 +14

Buschur Racing Intake +1
Ported/coated stock turbo exhaust manifold +2
Buschur Racing turbo-back exhaust (with testpipe 3") (2+1) = +3
Forge MBC +4
Walbro fuel pump/FIC 950 injectors +2
BC coilovers (<$900) +5
RobiSpec Rear Anti-Sway bar +2
Hankook Z214 tires (245/40/17) +10
Removal of trunk carpeting +1


Do these following mods add points or not?


1) ('06) OEM Mitsubishi Evolution IX turbo swapped in for my old VIII turbo.

2) Aftermarket 02 housing (coated/ported)

3) Stock Ecu tuned via ecuflash/laptop. I'm assuming it's +10, but just want to make sure.


Here's a link to the classing pdf if needed.

Any concrete answers/help would be much appreciated! Thanks guys!

 

These are always fun. It is difficult. I looks like your trying NASA-X? The point system you're quoting looks like PT/TT rules, so I'll assume that!

Let's start with your additional questions:
1) Bam; you need dyno classed!
2) O2 Housing costs pts...
3) stock ecu tuning is now free - 0pts

Story about #1 above:
My friend rebuilt his 2005 STi but wanted the newer 2008 version turbo. He had to get dyno classed by the main TT guy. He submitted the paperwork and received a new base class with a specific amount hp and weight he had to make.

 

Thanks for the quick response! This is just for Nasa-Autocross.

So if I don't get dyno'd (No AWD dyno's around here, unless you drive 5 hours), I'm assuming I automatically go to NASA-NXS then, right?


I'm assuming they wouldn't take DLL or Evoscan HP/Torque calculator graphs, right?

 

I'd email your local director right away. They should be available for these questions.

I found your thread on the NASA forums too and replied to it as well. If nothing else, it'll serve as a bump for more attention hopefully.

My other thought is perhaps you could adopt the 06 base class of B (since your 03 is C** which is lower). But dunno for sure.

 

Thanks for helping! I appreciate it.

I did email the Midwest Director, so we'll see what he says! I'll post up when I find out more info.

I do like your idea about starting off in class B!

 

I use this calculator:

It might not be 100% right, but it certainly is easier than reading through the terrible NASA docs.

 

Oh yeah, if that's the auto adding one; it's great. I think it's updated with the 2009 rules.

One thing I can't find listed anywhere specifically is an O2 Housing. I personally would like to know what this counts as as well - as I'm mapping out possibilities for 2010 already (it never stops). Not sure if it's part of the extended exhaust or?

Anyone know the pt value for an O2 Housing??

 

IMO the o2 housing is included in the exhaust.

The only question I have is where a 3 port boost solenoid falls.

 

I added up my mods and I'd be at something like a +70 for my '03. Guess I'd land square in TTS or TTR, ugh.

If you have crazy pts, you can request a dyno re-class. I know of a few people that did that with success.

But if your modified (depends on # doors, drivetrain, tiresize) power/weight is lower than 8.7:1 - you're gonna be in TTS/U/R - yeppers. And if you're not running the stock turbo, that's where you're gonna land!

 

You dont land into TTR due to points. You land into TTR if your adjusted w/p ratio exceeds TTU. TTS, TTU, TTR is based on your w/p ratio. And each of those classes has a limit. Your adjusted w/p ratio cant exceed the following numbers:

TTS: 8.70:1
TTU: 5.50:1
TTR: Unlimited

 

^ Yeah, I know, that's why I said TTS or TTR. I have no idea where the w/p ratio would put me. I guess I'd have to determine it for myself and then tune the car to what would give me the best chance on paper.

Yeah, basically figure out what class you think you have the best chance in. I would say that unless you have tons of money, forget about TTR. I would not run in TTU either because a w/p ratio of 5.50:1 is no joke. Besides, its probably going to be pretty expensive competing and maintaining a TTU Evo. At around +3200lbs, youre going to need to make around 570whp to be relatively maximized given your adjusted w/p ratio. But if youre up for the challenge more power to you. I think TTS is the best class, but keep in mind that im speaking for myself.

 

So let me get this straight ... after poring over the rules again, am I correct in this assessment:

TTS = p/w ratio of 8.70/1 or higher (e.g. 9/1, 10/1)
TTU = p/w ratio of 5.50/1 to 8.69/1

If that is right, I'm already in TTU, since 3200lbs/420whp = 7.61/1 and if I were to shave a mere 200lbs off the car, which would be easy, then I couldn't make more than 535 whp (also easy), to stay in TTU.

Kind of a ghey system if I stop to think about it, since the p/w ratio would promote building a WRC style car, with a really fat low-end/mid-range and no topend to keep it under the HP limit. Very much favors an FP-Green style setup and letting the boost taper off on the topend.

Personally, and forgive me if I haven't read enough of this post, but it's best to go out in your region and see what the other class cars are posting time wise. Then compare to your setup and your skill times. THEN determine where you want to be, based on budget also. Like the rest of us, we do this on a negative budget (this year anyhow) at 0 power level compared to 80% of the evo's out there.
