TB Porting?
Thinking of porting the Trottle Body...
Is it worth it? more torque? more HP?
how much should I pay for a porting job and what is the largest I can open up the TB?
Im thinking of doing in this but whant your experience/advice
by the way...
I done heads/cam/headers,etc,etc...just looking for little things to get the extra edge.

Lingenfelter makes a 100mm throttle body but they only put it on their FI cars and when I called them about it said I wouldn't see much noticeable gain from using it on a bolt on or Head/Cam car.
I did have my stock 90mm TB ported and I did show strong numbers on the dyno (in combo with my other modifications) but didn't feel any SOTP difference when it was put on.

Ported TB, aluminum flywheels, electric water pumps, lighter wheels, UD pulley's, the FAST manifold, full roller rocker arms, 1/2 a point in compression.....you could go forever with the list of things I have seen people say made little difference and dont add anything that can be felt SOTP. Add them together and you have the reason Tony Mamo got 490rwhp with a 5.7 liter engine with a 224/228 cam and box stock AFR heads (sick low end throttle response with ton of TQ in the 3000-4000 range where big cams fart out)
Port the TB and put little faith in 'not worth it/value judgement' opinions. Do it for yourself and when people with 'nearly' the same mods, such as your cam and heads, cant figure out why you have 28 more rwhp than they do when they left out the 4 or 5 'not worth it' mods, then you can tell them why it was worth it.

Love mine- throttle response is instantaneous at mid revs and up. It's so crisp, you can actually get into a PIO loop- that's pilot induced ocillation in the aircraft community. Jerking, in otherwords if you're not paying attention. Took me a bit to get used to, but I love it now.

it's not always the individual part that makes a difference, but rather the combination of parts the exhibit the best gains. even small mods. can give you an advantage over an otherwise identical configuration.
