Hey Guest👍👎 We're looking for reviews of your local CUPRA or SEAT Dealership - it's quick and easy to do: Leave a review now
240bhp no front mount?
- Thread starter akchappers
- Start date
the head isn't the restriction it's the turbo, fitting the bigger port AGU head won't make the turbo flow any more, I've read somewhere on this forum that the big port heads only show gains over the small port on big turbo'd engines
Yep as that's what mine is pushing ... well 237bhp ... but heat soak IS a major problem at this time of year.
Im sure heat soak is a myth unless your stuck in traffic....and if you are well you wont need the power lol
Log substained runs in 3rd-4th gear to redline on a mapped KO3 / KO3S and see what I mean using the stock cooler - its not a myth at all. Timing pull can be seen clearly from the logging which is due to the high EGT's.
Yeah but the turbo is going to super heat the air anyway, thats where your intercooler comes in.
from my experience on turbo engines heat soak affects the inlet manifold, there's a sensor in the inlet manifold which monitors heat and when the heat of the inlet manifold rises the sensor senses this and pulls the timing, take your ibiza for a quick blast and pop the bonnet as soon as you stop, the inlet manifold will be coolish depending if you have a good fmic, give it 5-10 minutes and feel how hot the inlet manifold gets, there is gaskets which you can buy from the likes of badger 5 which reduce this problem, I've heard the standard intercooler struggles to keep the inlet manifold cool after afew blasts on a dyno which is why they normally set there highest power runs on there 1st or 2nd runs any more and it's a waste time, yes you can get heat soak through your air filter but it doesn't affect these engines much at all if you run a decent fmic
Well bottom line is I think he's telling me porkys!
Probably why he didn't want to chat! Apparently he is on here but I've never seen anyone off here not want to talk about their cars and mods!

he was probably scared you knew to much about these cars as he can bull **** easily to wanna be chav's in there saxo's and 106's
I can appreciate that... from memory repeated hard driving especially in the warmer months you could feel it wasnt as responsive.
You can get the figures mapping and dyno wise, but living with it is a different matter.
I did just hang around to see if he would come out! I was gonna show him up! Il see him soon enough!

That sensor tells the ECU the temperature of the inlet air as it enters the cylinders - the temperature of the manifold isn't really relevant.
The ECU will use the temperature reading to modify the amount of fuel injected. Hotter air is less dense, so contains less oxygen per cylinder-full, so cannot burn as much fuel as colder air. Inlet air temperature directly affects the power output for this reason.
Inlet air temperature doesn't affect spark timing directly.

thats what I was lead to believe, all I was getting at was hotter the inlet manifold gets the hotter the air is going to be going into the cylinder, I was wrong about the sensor pulling the timing then, but the sensor is affected by heat soak from the inlet manifold cos to be honest the inlet manifold gets baking hot so it's impossible for it to stay cool when the outside and inside temperature is so high
PS do you stalk me or something??
