Throttle body boring compensation.
Monday, June 08, 2009 2:34 PM
Im getting my TB bored over, my question is will my computer automatically adjust to more air coming in or should I adjust for it in HPT somewhere? If I should use HPT which tables should I be looking at?

you using the MAF?

if not, it won't be compensated for. you should be retuning the VE tables.

althought I doubt increasing the bore of the throttle body by a mil or two will make much difference in overall flow.

IIRC, his setup is MAF, but it's still a good idea to tune it rather than rely on the sensors to compensate.

How far are you boring the TB? Also, are you boring the UIM at all? (I don't remember the diameter of the opening on the manifold)

Nate, you might want to check out the cams they offer at WOT-Tech.com. They've got tons of options (you can pick from a huge array of lobe profiles, and mix and match, plus order your lobe offset and separation. If you were to couple the right cam with your bored TB, it should wake up that engine very nicely without making it to tempermental on the street.
