standard internals limit

[cupra_spencer]

Hi all, im new to this forum so please be patient with me. finally got myself a MK3 cupra and have big plans for it. However does anybody know the kinda power limit before having to forge the engine? iv heard around 350bhp but would like to hear this off a few more people.?

Any help would be much appreciated.

Most people say over 330 and you're pushing it. All depends how far you want to push your luck.

If it was me, I wouldn't run stock internals over 300 BHP

 

[ian_cupra]

depends on the set up you got too i think, hybrid is on the power quicker than big turbo's, so the internals cant take as much as the power is full on very quickly, wouldnt go over 300 on hybrid, if big turbo, i'd go upto 320 max

 

[cupra_spencer]

just bought a 248bhp cupra off piston heads and wondered how much further i could take it, thats all. what kind of boost pressure can you run safely with the KO3s?

 

[ian_cupra]

thats it running at about its max mate already

 

[JJ_arosa]

next stage would be to go k03s hybrid or ihi

next stage would be to go k03s hybrid or ihi

Bit of a jump from one to another there isnt it jamie?

Around 300-350lbs/ft of torque seems to be about the limit.

I've been told std internals would take 340/350bhp but i wouldn't and ain't trusting it myself, it's only what i've been told so may not be gospal!!!

 

[cupra_spencer]

is there any chance of more power without going bigger turbo again? do any of you boys think about flowed heads, cams etc with your setup?

 

[Damoegan]

Not with the K03s mate. You are already pushing it to the max now.

 

[cupra_spencer]

yeah but i dont have to increase the boost to flow the head and fit high lift cams.

the ignition timing and fueling may need altering but boost should stay the same.

im not really new to the modding world but am new to turbo's.

had a saxo vtr beofre the cupra.
started out life as a 90bhp 1997vtr. i then dropped a vts engine in and with various mods including fully flowed engine (head, inlet, throttlebody) and a set of high lift cams (catcam 708's) it made 147bhp @ the wheels after spending 8hours at chipwizards in rochdale being mapped.

 

[ian_cupra]

no, basically, need a bigger turbo to get more power

 

[cupra_spencer]

ok thanks for your advice.

 

[JJ_arosa]

bigger turbo mate people dont seems to cam these engines not realy worth it when you can just buy bigger turbo lol

happy with the speed of my old car then mate ? it did go very well not a patch on my new one though

 

[cupra_spencer]

YES MATE. I AM VERY HAPPY WITH THE SPEED. (sorry caps) i think the filter is too far down though (being behind the fog light)
It gets soaked in wet weather and that trips out the MAP/MAF sensor which is why it was going into limp mode. now that its stopped raining were boosting off the gauge...

got a few sneaky plans watch this space! lol

 

[JJ_arosa]

good good for the price you would not have got a cupra with all the mods else were lol

glad your happy
