Indy Teardown Warning

Ken Miele · 08-14-2019, 04:53 PM

A member sent me this email below that they received from the D1 Stock Super Stock rep. I am surprised it has not been brought up sooner. This also may have something to do with the newly purchased digital scanner by NHRA. From what I here from the grape vine, they will be looking at cylinder heads with this scanner. The question I have, with the lack of tech officials and man power how did they possible get all the heads scanned, there has to be hundreds of heads used today. Shouldn't they have told Stock and Super Stock this will be the new standard. Also when scanning, do they take into account core shift. I also heard this was a major concern with the Showdown cars, maybe that's the reason for the low car count for Indy.

Interesting topic and I would like to here more opinions good or bad.

Unfortunately I had to delete the email as a request by the sender. In my opinion we should know whats going, this is why I posted it. Although I am a D1 racer I don't receive emails from the D1 rep because of my affiliation with Class Racer, draw your own consultations. NHRA has made their own announcement on this subject.

First of all, anything to maintain the integrity of Stock Eliminator is
good, IMHO. My question is, and we will use a 396/375 HP combo
for this example: NHRA tears down three of these combos, and
digitizes the heads. One has heads by Gary Hettler, one has heads
by K.B. Racing(Line Performance), and one has heads by Jeff Taylor.
Which one becomes the new standard? J.R.

Sounds like a 2 tenth slowdown coming to a town near you lol.

On the head question

I'd say the one that passes is the one that matches the completely
stock casting head as per factory or the approved nhra head of choice would be my guess, but idk.

The ones from Edelbrock or Chevrolet

None of the above. You can only assume NHRA has been scanning untouched OEM heads, you know "stock".

LOL........It sounds like there won't be as many stock racers crying to get an increase of the Quota so they can enter to me. At least the really fast ones.

How will they deal with intake manifolds that have no 'spec'?

Tough to put the genie back in the bottle..... -Al

J.R. Haddad · 08-14-2019, 05:47 PM

So if the stock castings, assuming NHRA can locate the hundreds of
castings that are in the guide, are the new "Required" runner shapes,
but the cc's are the current published ones, will the trend return to
acid dipping(or whatever new process' are available) to get to the
desired cc's? The sharp head people out there won't roll over and
retire. I see more expense coming for a lot of racers. J.R.

They may not have a "spec" but they sure can scan them as well. I guess Cdn intakes are going up in price. LOL

Anyone who actually encounters the process of having the head scanned @ Indy want to volunteer to inform the rest of us how it's actually put into practice....

I'm new to this game, but have been lead to understand that in years past certain things became "Accepted" based on the first head or some other parts because NHRA didn't have an OEM one to spec so they spec'd off the first one through teardown.. Meaning the "scan" could be based on the guy who gets scanned first not the actual untouched head... I have little faith NHRA has sought out each and every head in the book to scan them prior to using this new technology.. I also have little faith the Manufacturer's..those that are still in business would provide them with a CAD file they could use to compare a fresh scan to.. So what are the basing the legality of a scan off of?? They may have picked up scans of all allowable "Showdown" cars as that is only a handful of heads to scan.. but for the rest of us this seems to be a little less enforceable.. I can tell you if my untouched heads are deemed illegal because another car that had heads that had been massaged on gets scanned first, this technology will in fact be useless to me...

just my .02
