As long as you aren't putting little hats on them and talking to them.

Dave, following your logic, the engine would be illegal the moment the carbon was viewed, correct. 

 

 

 

 

No logic involved. Just pure BS

Damn it Todd stop telling everybody about my engine building rituals.

[chris haldeman]

oh, so I'm not the only one that dresses an engine on the stand with it rotated so everything goes on perfect...

Likely you are not the only one but I could see many less experienced people not catching it

[Bench Racer]

I get it big kids, only the big kids are correct. Have the big kids ever noticed many of the little kids may lurk but keep pretty quite.

[B(Kuch)Kucera45]

Now that it's in the open can anyone explain the exact gain of the turn signal removed and the manifold grinding in hp or TQ ?

I know the turn signal removal will help with the heat soak problem but can't see it adding any power because it's not a ram air system. So the only gain would be from the manifold grinding. So how much are we talking about?

[Andy Mitchell]

Haha.. Sorry if I sound cranky, but it's been a long day.

 

But really? 50 pages of forum discussion, a physical study of hardware options by Mazda/SCCA and all the 'experts' recommend for the 1.6 is to pull a turn signal light?

 

And, to top that off, somebody says that they tested, and the headlight has to stay in place because it would be too much to remove it? 

 

This is a strange, strange place.

I know one who is never quiet and when he speaks most don't even know what the hell he is talking about.. Does that count?

This was in there too.

What Do You Think

1. #17843 (Jim Drago) Compliance Program
The CRB is seeking member input about the possibility of re-establishing a compliance fee on Spec Miata
entries in 2016. Please comment on the following to crbscca.com

 
Establishment of a Spec Miata compliance fee:

 
1. Should a compliance fee be established? Yes or No
2. If Yes, should fee be charged at both Majors and Regionals and be used for compliance checks at all
events”
3. Should fee be charged at Majors only, and be used for compliance checks at Majors only?
4. Majors only - What fee would be appropriate?
5. Majors and Regionals - What fee for Majors and what fee for Regionals?

 
Use of funds:

 
1. Should part of the fund be used to compensate competitors for extended tech teardowns if they are found
compliant?
2. Should fee be used to increase frequency of tech at more events?
3. Should a sealed motor program be instituted and funded by the fees?
4. Who should administer the program?

1. #17818 (Ralph Provitz) Throttle Body/Restrictor Gaskets
In GCR Section 9.1.7.C.1.k.1.d., add the following language:
"....and must not be modified. An OE (or equivalent) gasket shall be used on both sides of the restrictor plate."

 

 

2. #17821 (Jim Drago) Compression and Carbon
In GCR section 9.1.7.C.1., remove section j. (compression ratio table) and re-letter the following sections.

In SM spec line, add "(without carbon)" to the Bore x Stroke column. 

 

You made a post saying the Ralph's gasket request point 1., is SOOOO stupid!

 

Well big kid your request point 2. to add the words without carbon in the spec line Bore x Note column is so stupid. Non of the other SCCA classes have the without carbon note in their Bore x Stroke or Note column. That ^ should be clear enough for you to understand.

C'mon, can't we legally repair 1.8 NA exhaust manifolds?  I just found a 1/8" crack last night at the collector on mine that I would sure like to repair...

I think you should be able to weld any exhaust on the outside OD as there is no gain from it at all !

This is a strange, strange place.

And they wonder why some of these division are starting a separate class for the 1.6 !

Oh I forgot there only doing it so everyone gets a trophy !

Yes you can and always could. No Miata specific wording or ruling nessasary. Standard repair procedure with no performance gain. Atleast in my mind

[Steve Scheifler]

I agree. I think it is sometimes difficult or impossible to repair at the collector from the outside but to the degree that you can get it to last, it's OK. The bigger issue for me has been new factory parts with lots of grinding already done inside. Is that not an issue for any 1.8s?

[LarryKing]

Could we allocate a portion of the compliance fund to buy Johnny some syntax?

I don't want Walter spending his hard earned money on me.

I'll try harder, free of charge. (one thought)

Anyone can also PM with "What" ?? (another thought, on same subject)

I'll try to keep my train of thoughts on the tracks. (another thought, on same subject)

I know the turn signal removal will help with the heat soak problem but can't see it adding any power because it's not a ram air system. So the only gain would be from the manifold grinding. So how much are we talking about?

 

From our testing we saw roughly 40 degrees drop in intake air temperature by removing the turn signal assembly.  Basically it takes and makes the intake air equal to ambient plus 2ish.  The theory is that colder intake air temp equals more HP.  I think the rumor is like 1hp for every 10-12 degrees of reduction, but I'm not a motor guy so I will defer to someone who is.  I can say that at a couple different tracks we saw roughly 2mph increase on all straight aways long or short, so it appears the car was getting off the corner better.

 

On the header grind, we saw no gain until 6K when it was like 1.4 and then at 7k it was like 1.6 both HP and TQ.  This was an engine dyno, not a chassis dyno.

[Sean - MiataCage]

Thanks for the efforts to this point.

So these are the CRB recommendations still open for feedback prior to board approval, correct? And I believe wording can still be tweak or even minor changes made.

I would like to know why the turn indicator delete recommendation did not include removal of that side headlamp bulb, the location of which likely limits the effectiveness of the new rule. Was it discussed? If yes, exactly what were the arguments against?

 

We saw no difference in on track testing with or without.  The intake air temp never got below ambient.
