My S10 ZR2 build

You know, something just occurred to me. What should I do about the vent line coming from the gas tank? I don't know where it should be ran on the TPI setup. I know that I don't want to make it a vented system like from days of old and I don't want it just leaking onto the ground!

EVAP purge solenoid was mounted on charcoal canister on early C4 Corvettes.
Not real vital where purge is mounted at.
 
Thanks for the reply. I'm under the impression that it should be attached to where there is a slight amount of vacuum, but I don't know for sure either.
 
I've been looking over the trans cooler I have. It's the plate cooler from a Caprice with the 9C1 option. Nice cooler but after I read the links grumpy posted I'm under the impression that, the bigger the better. It seems the cooler the trans runs the longer the life. Since I'm not using an A/C unit in my truck do you think the condensor would be too much overkill?

No do not use the AC Condenser.
It was designed for AC Freon Gas & liquid flow.
Too restrictive as an engine oil cooler & transmission oil cooler.
 
yeah Ive seen several guys who used air conditioning evaporators as fluid coolers and yes its always restrictive, too flow,
the tube size is way too restrictive,
your far better off buying a commercial fluid cooler with a power fan, version designed for that application with AN#8 or 1/2" tube / hose size

Ive been using this recently on my transmission, as my 10 qt custom oil pan seems to provide adequate oil cooling by it self

heres a similar dual trans fluid & separate engine oil cooler

you will rather obviously need to carefully and accurately,
measure the location you want to install any fluid cooler and its fluid line connections, you should seriously consider a AN#8 line size as minimum

This is the Hayden #679 Trans Cooler I bought for my 1999 Tahoe.
I rebuilt the 4L60e and put all the good parts in.
About $1400 spent.
I use it as a stand alone.
No issues. Driving all winter and getting down -10F tonight.
Holds Trans temps for me at 140-175 F all the time.
I bought a good Hughes Tow Master torque converter.

Moroso Racing Transmission cooler 41205.
Made for drag racing with a Trans brake.
I bought and use it on my 1963 Pontiac Gp.
Holds Trans temps the Turbo 400 at 100-120 F all the time.
No fan.
I use as a stand alone.
Exceeded all my expectations.
With #6AN Aeorquip Teflon hoses and Steel High pressure fittings and adapters I spent about $450.00.
Cats Azz.
Need $$$ to use and install right.
 
"yeah I've seen several guys who used air conditioning evaporators as fluid coolers and yes its always restrictive, too flow,
the tube size is way too restrictive,". I'm not doubting what you stated, just wanting some clarification on how the condensor would be restrictive. Is it the cross section of the pipe itself or the length of the piping? Or both? The reason I ask is because when I was thinking it over some, I was under the impression that the transmission lines are just approximately 5/16 inch i.d..

The Hayden #679 trans cooler I bought for my Tahoe is just $43 bucks.
Awesome deal.
Add a Small Fan and Grumpy will be Happy !
 
larger cross sectional tubing tends to allow the volume of heated transmission fluid moving through the heat exchanger or radiator,more time during its passing or transport,
to spend a bit longer in contact with the internal surfaces of the heat exchanger or radiator, thus the fins on the outer surface of the tubing can more efficiently transfer heat to the cooler outside air.
transfer tubes are generally designed with lots of 180 degree turns to maintain turbulence to hotter fluid is constantly blending with the inner surfaces slightly cooler fluid.
if the transmission tubing is AN#6 and you feed it into aAN#8 heat exchanger tube design, youve gone from about a .110 sq inch cross sectional area to about a .196 square inch cross sectional area,

thus youve slowed the fluid speed or the fluid molecules, in contact with the radiator tube by about 56% while reducing the flow restriction and not reducing the fluid return flow a bit.

Ok, thanks for that explanation. One more question. From the diagram above, is the remote oil thermostat really required or can this system be run without it?

I run without in my Chevy Tahoe.
When the 4L60E blew failed it sent all the trash into the new radiator cooler and plugged it solid. It would not flush out.
To correct I would have to buy a New radiator.
I did what every single fast drag racer does in the USA or at least in Illinois here.
I bought the transmission oil cooler of my choice , Hayden #679 I installed it as a standalone.
It works fine and keeps the trans temps in check better than any factory layout.
I have driven as cold as -10F air temps this winter with the Tahoe. Absolute no issues.
Still the trans temps maintain 120-140 F.

I was told by everyone I had to plumb into the radiator in series on the Vette forum.
Well not a single one of those guys ever street raced against 10 & 9 second drag cars like me nor ever made a pass down the 1320.
