is ok to bypass the coolant lines to the throttle body? and would there be any negaqtvie or positive effects?
 
Funny I just had my throttle body off-I By-passed it!I figure they[factory[put it there for cold starts-Mine's more of a summer car!
 
You really don't need the coolant lines. They are there to keep the throttle body from icing in cold weather. There isn't any real negative effect in removing them but on the flip side there is no real positive effect from removing them either.
 
less heat

you don't want hot coolant going through the throttlebody...cooler air makes more power..........Bob
 
A few years ago we ran a test at the track with and without the coolant lines and it made NO difference. :rolleyes: This was on a high 11 second car.
 
I pump Nawwwzz through mine, and I gained 150HP. That's right, one hundred and fifty horsepower!!! The nitrous super cools the throttle body and it makes the intake temps drop about 200*. It was the best and easiest mod for 150 horsepower I have ever done. (except for the whistle-tip exhaust, that was easier and made a bit more power) I was amazed that it could make that much difference, but I had it checked on dyno. (Deeno the dyno in Bedrock) Nawwzzz is some great stuff. If you add a couple of stickers on your window, it'll help verify the power gains. Putting the stickers on perfectly crooked is the real hard part, though. I heard that some guys tried using nitrogen, but it just didn't have the same effect as naawzz. I also heard that the Vin Diesel GNX has naawzz pumping through the throttle body coolant passage, too. Them Hollywood guy really know how to build power!! That's why I did it to mine. I read about it in TMZ magazine, and verified it on Hot Rod TV. There's some real cool stuff coming out for our cars, thanks to the Hollywood directors that know more about horsepower than any of us do!

OK, now the real story. I always remove the water lines, but it really makes no difference. The air is passing through too fast to pick up any heat. But I still remove them.

Ken you have been inhaling too much nawwwwwwwwwwz.....:eek: lol.....
Agreed. most of us just loop'em and be done with it. I always wondered why reproduction coolant hardlines weren't made without the nipples:confused:
 
What I would suggest

Just to be save as I never liked to cap the lines (I have seen more than 1 blow) I would remove the hard lines--take them to someone with a set of torches and acetelyene weld the ends closed.
 
No leaking.

coolant lines

i knocked off a second and gained 7 mph in the quarter by unhooking mine.....Bob
 
Now for another one of those "cause knowlege is power!" moments;)

Some guy that had way too much time on his hands dyno tested the coolant bypass mod on an LT1 camaro. The car was COMPLETELY stock. It gained 5 rwhp and 7 ftlbs of torque. Haven't done it to mine yet though, too scared of the throttle sticking half open when it's zero degrees out with snow on the roads;)
 
I think this was one of the first ever mods to a turbo buick. I have my coolant lines brazed shut also.

Don't forget to crush your fuel pressure regulator to more pressure...ha! (seriously...don't do it!)

Man That WAS the way to make more power "back in the day".:D I would take a fuel pressure gauge to the track and a 5/8" deep socket (had one anyway, 'casue I HAD to change plugs after every other pass 'cause I had melted the tips off!:eek: ) and a hammer and SMACK the top of the regulator to up the pressure. (if I needed to lower it, I used a slide hammer to pull the top back up..................................not really) But I also did that to few other guys cars at the track, so they didn't melt head gaskets like I use to. I have changed head gaskets on the side of the road down the street from the track! Had it done in 10 hours with just hand tools! I'm not that fast anymore. Too old and broken for THAT kind of wrenching.:mad:
I did run a best of 11.77@112 with stock injectors, Don Kieger chip, (WHO'S THAT?;) ) stock turbo, stock intercooler and an external Bosch 286 pump. With a set of AFR ported iron heads and a Crane cam, can you say L-E-A-N? :eek: :eek: The biggest injectors back then were 30lb Tomco's, unless you wanted to step up to a Haltech ECM that required a masters degree in computer science to program.
Thanks for the memory...........er........nightmare!:D

Becareful with how much nawwwzzz you pump...you don't want to blow the welds on your intake. Then you won't be able to live your life a quarter mile at a time. And always remember...you can have any beer you want as long as it's a......ahhhh heck with it. :rolleyes:
 
BUDWEISER!!!!! Use to work for them guys!!! Here's one of the engines I use to build for them. We had 12 complete engines ready to run at the beginning of the season. Run time was about 45min total, then overhaul time, if they weren't "windowed". Also here's what a Griffon (2,240cid Rolls Royce V12) piston looks like with too much naawwzz. (nitrous for us "old" guys):eek:

That's how I crushed my regulator, a socket and a hammer. I had the external pump too. Went mid to high 7's in the 1/8 mile. I had my fan relay on a switch that I could ground it out and make it run whenever I wanted. High-tech! Those were the days when you couldn't wait for the new ATR newsletter, GSXtra or Kirban's newsletters to come. Kenne Bell's catalogs where everything was worth 2 or 3 tenths in the quarter.
 
I think we have hijacked this thread too much already. BUT....I remember the ATR news letter being a good source of info. (some of it bogus) but the KB catalog was entertaining. Jim was famous for exagger......err........embelishing his parts. I added up all the time savings in his catalog, and if you bought all of his performance parts, you could have given John Force a run for his money, ..........and probably WON! (But, only if you used his watercooled up pipe!!:rolleyes: ) Martyrs we were!:cool: I've been racing/building these things for 20+ years. Makes me feel real old when I say THAT!:mad:
