94z28 what if any gains are expected with this mod?:reloading

2

minimal

3

worth doing but its anot a power gain mod

4

then why is it worth doing?

5

helps keep the TB cooler supposly, its a freebe mod

6

no no, not whats it do… Why is it worth doing? If you don’t get performance gains, except for better drivability with it hooked up, then why is it worth it?

ahhh yes and the man presents a good question:boink

8

ahh yes what a fine question.

Nice reference. Though you need not elaborate to me the WOT power benifits of keeping the intake air charge as cool as possible. I was just instagating quick for recomending something with absolutely no reason at all. Especially when he stated so himself. just a little devils advocate. :stick:

another article.

and here’s a list of some other related articles

60degreev6.com what the hell does that have to do with the price of rice in china???

13

First, are you insinuating that a 60degreev6 is not domestic? because its a GM engine series…
and wow, I didn’t know a V8 used different earthly physics then other engines :booty:

point proven:fart:

its worth doing just to keep heat out of ur TB!

16

did it today thanks 4 the help

i have done it…

the TB bypass mod helps keep the tb and plenum part (on my TPI motor) cooler. all that hot motor coolant goin into the TB/plenum area is not a great thing. it rapidly heats up that area and does help heat incoming air…

after driving around in stop and go traffic, the motor on my car gets hot, the fans turn on late… up over 220 degrees. i need to get a thermostat/etc…but anyway, when it gets that hot, it really heats the TB up too. that overheats the incoming air. with the bypass, the TB does stay ALOT cooler

so while your driving around, the motor might be running at 180degrees, but the TB isnt at that temp too. which makes better power when u need it. i’m not sure how much, but i’d guess 5hp at speed in the right conditions.

its very noticeable. drive around for 30 min with it hooked up and touch the TB/plenum area. then do it again with the TB bypass, and notice how much cooler it is

The reason the manufacturers put the coolant into the throttlebody is to warm the air… It increases fuel economy because the fuel vapors mix more evenly and quickly in warm air… IE fuel economy!

19

and supposibly tokeep icing down in the throttle body in cold start ups and driving. :dunno:

i did it on my last T/A, makes a lot of common sense to do it, but the gains are minimal.
