160* TBI that is. Just wondering since that is what I have and hoping that is the problem.

I got much better throttle response and even better gas mileage when I switched from a 160 to a 180 thermo.

i have a 160 degree thermo, open element k&n, hood scoop, electric fan switch, bunch of other mods on my tbi and i get very good throttle response and awesome gas mileage, i get like 450 miles on a tank (considering my '82 camaro that had a 355 got like 15mpg on premium, lol), '91 camaro rs.

 

ROFLMAO...unless there is something im not getting, and there is something else called a t-stat How the hell you gonna get betta gas milage by changin the t-stat? How ya gonna get better throttle response? I thought the car is suppose to run cooler or hotter when u change the t-stat. LOL And not to be rude edin but 450 mpg on a tank of gas? Do ya have a 2 cyl?

 

rally it isnt unbeliveable. If he has a 15. gallon tank that would turn out to be around 29 miles to the gallon

 

road trippin, i get around 375 miles a tank

 

im not making it up, i was just estimating, i filled it up, clicked my little mile logger thingie, and drove from charleston area down around daytona (enterprise), i got lost a couple times and drove about 420miles (almost all in 5th gear, which on my car runs around 3150-3200 rpm at around 80mph, when i arrived i was a lil over empty, not quite though, on the way back it only took me like 370miles (i took a better route plus didnt get lost), filled up right before i left, and when i arrived i had between 1/4th a empty bout half way left, so, im just guessin here on the accuracy of my fuel needle thing, lol. btw, my city driving gas mileage, now... that's another story! ugh.

 

also, my car temp reads my engine is usually real cool, my funtional hood scoop, electric fan, and 160 stat keep it pretty cooled off, not sure if thats a good thing to an extent, but the temp gauge is usually somewhere between the first line mark (not sure what it was) and the middle 220 mark.... its usally a good distance from 220 though.

The thermostat has a good deal to do with throttle response. I know when I had my 160 in the engine was running very rich and that made it very sluggish at lower RPM's, the 180 cured that pretty easily.

Edin, you have a t-5 I assume. Why are the RPM's that high at 80 mph? Is that common for all t-5's? I have no idea. I have an auto and at 80 mph my RPM's are still around 1900.

 

sounds liek 180 would be better for me, but I have a stage 2 fastchip and it says to use a 160 t-stat with it, what should I do?

I'm not sure what the temperature is, but if the engine does not reach it the computer will think the engine is not warmed up and it will keep it in a (choke) mode till it warms up, but it never does, it may help power some but the gas mileage will suffer, I have a 180 degree in mine and it gets good mileage 17 MPG was the worst it ever got and 32 MPG was the best.

i didnt think 3k rpms at 80mph was that bad, i got up to 100 and rpms only went to 3.2k rpm.... this unusually high rpm?

at 80 mph i turn around 2300 rpm with a t5

 

hey rally, if your not aware the tstat has allot to do, because it keeps your car temp at a certain amount, and without it, it messes up you mix in turn, and if you run rich, bad mileage, bad response,

all.in conjuction, with the tstat.
dont get 160 'less u have a chip designed, or a 'hypertech' switch which enables the fan to turn on earlier and cool down.
i think stock its set 220? and the fan makes it kik on earlier.. hope i helped.

I believe the stock fan setting is like 237. Ya its hot!! Last year my fan switch came on at 220 and i kinda like that. Well it went out so i got a new fan switch and now it kicks on about 237. I went back to the place that installed it for me and he said thats stock. I miss it coming on at 220. Ive looked at other fan switches and all i can find is on at 200 and off at 185. Wish i could find one where it kicks on at 220.

 

Look in a JCWhit catalog for adjustable fan switchs.

hey guys i got a recaro cross-fire tbi
in my car with a 160 stat and my fuel economy suffers!!!! 31 miles to the quarter tank in the city! after hearing about the 180 stat im gonna switch it today! it is true tho the 160 does give u less mpg.
im about to drop a new 350 carb motor in
what do u guys suggest for heads, cam, intake, and carb i use? on a budget kinda but any suggestions would be good! do i have to switch out the computers too? how do i do that!

 

hey rally, lookin summit, cooling section, there will be a JET sswiytch, that starts car at.... 200?
brb, going to reaserach and development room (bathroom)

ok... it turns on at 200 and goes down to 185 its 38.69 for 1983-92cam/bird...

Thanks i seen than...but like i said above..i wish i could find one that kicked on at 220. I know 200 isnt bad and if i cant find anything else thats what i will have to go with. I hate the sound of the fan and i think 200 it will be on a lot.

 

Hmm. guys tell me what you think, i have a dual fan setup, i rig second to switch, i drive round, leave fan on, pull up to ladys, something, turn fan off, etc, gets too hot, the other fan which is connected to stock setup then kicks on...

whatcha think????
