Default Turbo Without Intercooler



Hi Bro's and Sifu's

I was just wondering how a turbo car can run without an Intercooler (or any form of cooling system for the air ) to cool down the air coming into the TB from the burning hot turbine ? Yes it will run but for how long ???

This can be seen on the old skol Hyundai Coupe ... Made by Hyundai a turbo charged engine without an Intercooler ... An it works fine !!! Im confused ... I doubt that they made a cooling system for the turbine housing ... Even at low boost the temp. of the air will still be hot ... How is this possible ??? 10 Layer radiator to counter the engine from heating up???

I plan to BOT my Peugeot 206 1.4 and found this on Youtube (IF IM NOT MISTAKEN THIS SETUP ALSO HAS NO INTERCOOLER BUT CUSTOM MADE) ... Please drop ur comments about Turbo cars without Intercoolers and their Pro's and Con's ...



Long Live Motorsports ...

if turbo lower than 0.5bar boost can run without intercooler, bcos air temp is still lower n safe for ur engine! supercharger is 0.7bar can run without intercooler safely!

without intercooler= better responsive but lose max hp output
with intercooler = increase hp n can run more boost

when the charged air goes in hot it decreases the amount of oxygen it can carry thus it make less power opposed to intercooled air.

for low boost applications (less than 0.4 bar) you can opt NOT to install an intercooler. but if you do, it'll lower the compressed air temp more, which will translate in a better system.

but why you wanna BOT without using an intercooler (which is so cheap & so easily bought nowadays) is beyond me?

1st of all, it's a BOT, right? so it does not need to be a big , lag-inducing intercooler. you're limited to low boost (less than 0.6 bar) anyway. a small k-car sized one would do...really

Thx bro for the info ... Supercharger cannot compare to turbo cause supercharger use pulley system and the heat can only be caused by friction or engine bay heat ... Turbo is the heat coming out of the combustion chamber itself ... but then if 0.5 can run without i/c .. good enough ... im edy happy ...

Bro i coundnt agree more with u on the "why BOT without i/c" ... that is so true ... cost also how much only for i/c and piping ... but the main problem im facing is lack of space to do fmic (trust me ... i measured with L2 i/c also problem) ... i tried to measure for tmic but then that would mean i would have to do an air scoop on the bonet ... still no space ... plus if i were to do so ... that would mean i/m leaving my ECU's in the engine bay vulnerable to water if car wash or if it rains ... most of the ECU for the 206 is in the engine bay and the engine bay itself cannot be sprayed with water ...

so can i safely BOT the car at 0.5bar without and intercooler ??

Thx bro for the info

bro, i'd stick to lower boost, to avoid detonation.
do things right the 1st time you do it. problem with BOT is you always tempted to boost a liiiiiiitle bit higher. dat's why an intercooler was an option.

i oso think you haf to consider a custom intercooler for yur application. this is for a 206.

ah.. i drive an OLD OLD hyundai 1.5 with turbo. i can run 1-1.2 bar without intercooler..
but i scared la deep inside me.. its best if you have one..
and it will perform much better if you have at least one small intercooler like kancil type...

* bside.. i only boost that hight at night... hot days drive slow slow.. 0.5-0.8.

i think air fuel ratio very important , if u got lower boost but u run ARF too lean also can damange ur engine. fuel can cool down air temp inside cylinder!

that the way,u got the point,fuel can let piston cold down,a/f ratio is very important thing,any engine na or turbocharger engine running a/f ratio too lean also will damage piston,more octane more cold and more power~

but better have intercooler and blow off valve man~
