Trans shield Clarificaion
Was trying to clarify if a stocker with an auto tranny needed a flexplate and trans shield. The rule books says for any car running 10.99 or quicker or 135 or faster, except in certain stock and super stock classes. In the stock section, I dont really see anything except for people running manual transmissions. I hope it runs quicker than 10..99 but it wont run 135 or faster.
I know in other classes it has a section that specifically states an auto needs a shield , but stock was kind of vague. Thanks to anybody that can clarify this. Chris |

Re: Trans shield Clarificaion
The rule in Stock is 9.99. Or at least it was.
If you want or need a rule clarification, it is always best to get it in writing from Glendora, and keep it with the car.

Re: Trans shield Clarificaion
rule book says ANY car running quicker than 10.99 AND/OR135 mph must have both shields (flex/trans) and a ALSO SFI flexplate REGARDLESS OF CLASS unless the rule book specifically allows it--General regulations back of the rule book buried in the Auto Trans section--ya have to look for it---NO shields necessary if ya have an APPROVED aftermarket trans case BUT ya still need the flexplate---2012 NHRA rule book--Section 20 page 12 sub-section 2:14 spells it out for ya-- basically if ya can run faster than 135 MPH or quicker than 10.99 YES

Basically he didn't answer the question! You asked about flex plate and transmission shields and he talked about trans cases so I guess the question is still open. JimR

Re: Trans shield Clarificaion
For some clarification I posed a more specific question to N.H.R.A. Technical Department
From: peter ash Sent: Tuesday, February 21, 2012 12:03 PM To: Bruce Bachelder Subject: Re: Flexplat and transmission shields for Stock Class Cars Dear Mr. Bachelder Thank you for your quick reponse to my inquiry. As I am not quite sure your answer gives me all the information I may require, I wish to rephrase my question. In Section 20, Page 14, Rule 2:14 of the General Regulations. Does the phrase(except some Stock and Super Stock classes as noted under Class Requirements) exempt a Stock Class Car using an OEM Automatic Transmission case, running 9.99 seconds or quicker and 135 miles per hour or faster, from the requirement of an SFI approved Flexplate Shield and an SFI approved Transmission Shield ? Thank you for your time. Regards Peter Ash ANSWER: YES IT DOES. Last edited by Peter Ash; 02-21-2012 at 04:12 PM. |
