Yea John,
I to have heard that this can help. In fact I was going to try it out
before I reported on it to the group. I'm told by a guy who has done it
that it does work, but he had moved it up close to the t-body. The resistor
is an execellent idea, my buddy and I were discussing this very same thing,
it sure would be a slick idea if you could get the voltage right.
The guy told me of another cool mod-ever wonder why your truck runs so
good in the morning?(when cold). I always assumed it was because our trucks
just liked the colder air. According to this gentleman, it's because of the
water temp sensor-being cold on startup! He said to wire up a switch(like a
double pull one- I think) can put an additional sensor in the washer fluid
bottle and switch to that one when racing. Kinda like a N2O switch-he swears
it really helps, even more than the IAT mod.
I'll let another cat out of the bag. He also told me to get a MAP sensor
from one of those TA turbo cars-the rare one back in the 80s. Apparently
this sensor has a screw in it that's adjustable to richen or lean-out the
fuel curve. He says its totally compatible w/our system & also helps.
This guy which you are all probably wondering about lives on the East
Coast & has several decades of racing behind him. Dave @ Hughes Engines
knows him quite well. He has built up several Dakotas in the past (tubbed
out etc) & really know his stuff more than anyone else I have ever talked
to. He is retired know, but helps out a lot of the 5.0 guys w/their motor
problems.
I would have tried some of these things out myself, first to see if they
worked since I didn't want to waste anyone's time, but since it was talked
about already I thought, what the heck....
