Points Spot Check for potential modification


Recommended Posts

Posted

I went on the internet and I found this:

viewtopic.php?f=16&t=25420&hilit=individual+throttle+bodies

and this (probably out-of-date):

viewtopic.php?f=2&t=23532&p=175097&hilit=individual+throttle+bodies#p175097

 

and this:

 

  • 3) Aftermarket computer system (any non-BTM “stand-alone” or “piggyback”):
    +3 naturally aspirated, +10 forced induction
    4) Modification of the OEM air intake/box, air filter location, air piping to the turbo/supercharger/intercooler/throttle
    body/carburetor, or hood/fascia/fender air inlet(s), outlets, or vents +1 (air filter upgrade alone—0 pts.)
    5) Non-BTM, deleted, or modified/ported throttle body +2; independent throttle bodies +4
    6) Non-BTM or modified carburetor, fuel rail, fuel injectors, fuel pump(s), and/or fuel pressure regulator +2 (no points for
    fuel pump alone if using BTM fuel and timing maps, sensor inputs and ignition timing)
    7) Non-BTM, modified/ported, or deleted intake manifold:
    4 cyl. +1, 6cyl. +2, 8 cyl. +3, 12A & 13B rotary +2, all other rotary +3

 

So ITBs with fuel rails, on a V6, with a stand-alone ECU:

 

+3 for computer on NA car

+1 for airbox

+4 for ITBs

+2 for fuel rails

+2 for manifold delete/change.

 

+12 total?

 

Or does the +4 for the ITB assume the airbox and manifold items and then add a point? *(That would seem logical...and be +9 for the package.)

 

 

Also (somewhat separately):

Socketing and "chipping" the stock ECU (no separate unit, like a reflash, but changing the physical chip in the module): I assume that's covered under the "piggy-back" blanket right? so +3 for NA as opposed to a free reflash.

 

Thanks. Just trying to decide what to ask Santa for .

As written, yes. There are no assumptions. Specific exceptions for combinations are noted.

^^^ This.

 

How much of a power improvement per point spent or per dollar spent are you expecting? Almost always, points are better spent on upgrading tire compound.

/\ These.
