IHRA hp and weights

dean ribeiro · 08-26-2010, 06:50 AM

HELP!

I need a little help w/ figuring IHRA hp and weights:
what is the hp and weights for the following:

1. 98 Pontiac firebird (350 lt-1) hp? weight for SS/JA? SS/KA?
2. 99 Pontiac firebird (LS-1) hp? weight for C/FIA? B/FIA?
is there a hp advantage for the flat hood? if so, what is it?

Thanks in advance; as I could not seem to find a classification guide,

Sorry I dont have my books anymore but if you can wait until Danny Waters Sr. gets back from MIR (Budds Creek) this weekend he will be glad to help you. If you are going to Budds Creek then look up Danny or Hank Blankenship. Both are great guys and will help you.

I am pretty certain that IHRA rates both the ram air hood and flat hood the same, for stock anyways. Mike

Dean,the lt1 is 275hp for ss with a weight of 3195 for ssja, not sure about stk, but I believe the weight for b/fia is 3095.

Dean,

LS1 in a 99 bird w/auto is 342 hp in stock.

I believe this rule is new for IHRA in 2010, but nonetheless if there is a difference in rating between the ram air and flat hood, you have to take the higher hp rating regardless of hood you are running.

Hope this helps...

LS1 /auto Firebird

B/FIA = 3248 lbs

C/FIA = 3590 lbs

I'd double check the numbers at tech inspection but im pretty sure they are accurate. Best of luck!
