Hey guys,
As we all know heated intake air means less performance, so I took a page from the TPI/LT1 guys and bypassed the coolant running through the throttle body. I just took the 2 coolant lines that run into the T.B. and using a small piece of brass tubing connected them together. I've noticed a little bit of difference when the motor is warmed up. Just thought I would share.

 

im lost............. so you dont have any coolant going threw your throttle body now.

i have a thermocoupler (measures temp instantly) and ive found that the throttle body is the hotest part of our intake, even hotter than the intake right next to the heads.

what did you do with the coolant line that runs threw the bottom of the intake?

ive often thought about running freon threw those lines, but the pump to run it would probable cancel the extra power.

 

well i wont be using this car during the winter, and i got the idea because it's a pretty popular first mod with 4th gen camaro's (like mine!!) the way i look at it, why have hot coolant running through your tb heating up the incoming air charge, which i know it's designed to do when it's cold.

 

i know NOTHING about v8's let alone cars for that fact, but does bypassing the coolant on a 4th generation camaro actually yield any benefit? i mean, if you're coolant is on average between 175 and 195 (am i right?), whats the harm in running it to a throttle body at idle thats heated up usually at 225 or on up from that? or is the coolant the exact reason the T/B heats up on a camaro like that. just a question
peace

 

I am curisous where you came about your spacers and how much they ran ya.

I am running the bypass atm I will let ya know bout the winter thing.. although i have had no problems with it yet.. even in 25f

Maybe mine is a freak? =]

 

from my experience the only reason why coolant runs through the TB in fuel injected cars is to help with cold starts in cold weather and a little bit with emissions. its almost kind of like the heat pipes that connect to the air cleaners on carb. motors.

if you look at any of the boards for TPI or LT1 f-bodies or vettes the most popular first mod is the TB bypass.

torpedan:
good someone else who sees the benefit in doing this!

 

i by-passed my tb last night. (man i hate those damn hose clamps).
i was to tired to take some temp readings, i might do it today.

 

my company makes them for mazda 323s and proteges. we call them thermoshield gaskets. we've tested on the a 2002 civic si and made 10 hp in the 4500 rpm range. we're in the process of doing more dyno tests on other applications. we made good gains in torque as well. you can check the dyno results and applications listing at http://home.comcast.net/~nextgear/.

i've been waiting for an opportunity to talk them up on the forum but hadn't registered as a vendor and didn't wan't to throw you guys a sales pitch.

the price is 60 buck shipped. you won't have to do any cutting they will fit perfectly and are very good quality. we have an ongoing test vehicle [so far 2 years 20000 miles] to ensure that they are of the highest quality. we offer a three year warranty for full replacment.

 

was that 10 hp gain on a modified car or stock with just the thermoshield gaskets?

60 dollars is a good price for 10 hp.

 

it had a short ram intake and a cat back. basically we did a baseline with the existing mods, then we ran with the gasket for the 10hp gain. i keep waiting for people to realize that you don't have to spend a lot of money to get a decent gain in hp. k & n filter with our gaskets will probably net 12-15 hp, for 110 bucks.

did you check out the results at the link i posted?

 

Gro, what type of plastic are the spacers made of? Is it something you can find in a store?

 

you won't be able to find it in a store...at least nothing that is going to insulate like you need in order to gain the benefit from the mod. you're looking at plastic supply companies...but again my company sells everything you need. and by the way we'll be at nopi in september. if anyone is going be sure to look us up.

 

The biggest probelm with spacers is that for the price of one set (aroudn 100) i can buy a sheet of phelonic and machine them myself.. =]

 

dude. there's like no links on that page. can't click on the applications or contact button.

what's up with that?

 

sorry...we've been reworking the website. as soon as its up and running again i'll post the new address. i fyou need any information i can mail you. contact me at nextgear1@comcast.net and i can give you all the specifics
