Turbo Without Intercooler

[SYeNi69]

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 ... :wavey:

custom very CAI and low boost i guess(maybe 0.3 bar)..lol

 

[allance]

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

so tis peugeot 206 same as naza bestari 206 rite...if so u chk back hypertune but i 4got wic issue edi...theres a bestari bot done by RS Impressive

btw...if bolt on 0.3bar witout blowoff o anything even better...silent killer...

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.

bro, 0.3bar cannot be silent killer la..haha..

if without blow off valve the return pressure also can going out from your air filter,if wont believe u can try it your self~

 

[unknown1x]

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.

 

[allance]

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~

i think turbo carburator engine cant intercooler rite??
correct me if wrong :)

how come carburetor turbo don have intercooler?the old school lancer a175 is what engine?also got intercooler rite?

alots of drag monster not use intercooler... see below....

YouTube - FASTEST 4 CYLINDER CAR IN THE WORLD
YouTube - Magnus 2007 CSCS Final
YouTube - low 9second 1/4mile 900+fwhp 4G63 mirage dragcar
YouTube - Black Betty lives again Slowboy's RWD 1g DSM Drag Car
YouTube - 4G63 Dragster - Dyno Session

but all of them running on methanol ... methanol is acting like "chemical intercooler" ... but it will corrode alu & steel ... there ambient temperature also low...

-----------------------------------------------

can try water/meth injection if dun want to use intercooler...

------------------------------------------------

intercooler also not good if no airflow run through to cool it.... most run turbo engine want to hide the intercooler, spray black laaa, put big plate number lah... huhuhuhu .... it can make intercooler heat soak .... it cannot cool the charge air anymore ..... it will be the heater to the charge air.... hahahaha.... better not use intercooler if like that...

 

[HKS-GT2835R]

please dun be screwed by the drag thingy. the fella wanna low boost oni maa

 

[nan83]

yaaa... i already give the explanation right.... i not say can hi boost with no intercooler....

i just say can try water/meth injection for low boost.... but need to log the charge air temp. first @ peak ambient temperature.... but it not cost effective lah... need to topup the water/meth always..... better put intercooler lah...

better i explain why drag car not use intercooler is ok ...... they will get the knowledge ... if they see drag car no intercooler & do not have knowledge, they will say drag car also no intercooler... normal car no need lah... that's why sharing knowledge is good...

 

[panjang ensem]

dera syenie, mayb u should do up ur kancil first as it is already barai at bengkel ann.............

n dun forget to buy the wheel nukel from me.....ekekek

i've seen quite afew turbo application without using IC with my own eyes. There is a guy running T28 without Ic on his 7AFE AE92, boosting 0.8bar. Power Enterprise turbokit for MRS stage1 also doesnt use IC. Toyota Hilux also doesnt use IC.

But here i throw 1 question.

Given SC compressor producing X amount of CFM @ 14psi VS turbo producing the same CFM as SC compressor @ 14psi, will the air temp of both same?

here i dont really agree that SC heat can only be caused by friction or engine bay heat. SC DO compressed/pressurized air and once air get compressed, it does get hot. The only different is how its being driven
