TB Coolant Crossover/Bypass, Any Disadvantages?

[Dynomite]

If I have ANY PROBLEMS with any of my dozens of modifications or painting I will post up also

The GUY is a bit sarcastic overstating and missing many facts


Oh...chit

I'm betting we can trust you will share. However, the grain of salt here is that GM had to design for all customer environments. Yours is but one. And I have not seen were any tuner has done thorough environmental testing. I still believe the most hazardous is the "cool" and relative high humidity ones not the ultra cold ones. That is just my guess.
In any event drifting too far from stock will eventually effect resale. That is a fairly well accepted axiom. Is a TB bypass too far? I actually don't think so really.
Long live the true ZR-1

Scott, for such a purist, I'm surprised you cut you own gaskets from rubber.

It's a corollary of Murphy's Law. If you prepare yourself for having to get under the plenum a lot by using a self cut gasket and not having to pay for new gaskets all the time guess what happens? You don't !
(both have to get under there and pay the $)
But that argument of being a purist sounds like it would have come from someone else.
I just resist making unsupportable mods. If it's simple enough to be seen and understood by a novice then that goal is accomplished.
I do believe in having a ZR-1 with an LT-5 in it.
Ask yourself. At what point is it no longer a ZR-1/LT5 ?
I'm not talking NCRS but
ripping things off it and bypassing systems in my opinion makes having an intact LT5 dubious. And yet a nice chrome or polished plenum adds beauty. Each of us have to make decisions about what we do and don't do to the car. The more that hack a way the more rare a true ZR-1/LT5 becomes.
Will the real ZR-1/LT5 please stand up?

What Did He Just Say




I am so confused

[efnfast]

He said he thinks the value of our cars will go up some day and more origanal will be better. I think the only thing that is going to be more with my car is I'll have more fun.

I've had mine 16yrs. You have a bit of catching up to do in the "fun department"
Keep her maintained, keep her functional and keep her fun to drive.
These cars are exceptional. In that I think we can all agree.

I've got a question, I read all through the TB coolant bypass post but I can't find out what everyone did to block the vacuum line that goes to the plenum.
Did you use a piece of hose with a plug...
Looking to clean up my polished plenum.
Thanks

The vacuum lines need to stay, the coolant lines can go.
On that note, I came home at 17 degrees the other night. No issues that I'm aware of.

EXACTLY

You do not eliminate any vacuum line unless you have eliminated the secondaries



Install 1/8 inch NPT allen head pipe plugs (21/64 or 11/32 drill) two each side of Plenum (Two each TB Coolant and Injector Housing (IH) Coolant). The associated two IH coolant ports in the IH should also be plugged on each side. Total six coolant ports plugged One each side TB, One each side Plenum, One each side Injector Housing.
See Summit Racing for Aluminum Pipe Plugs.
See item 4 of LT5 Eliminated Systems
