power/tourque difference?!

[durva20]

Hi all!

so it will be a bit strange ... sometimes i feel my car like a power rocket ! after 2 minutes ill stop at the red light accelerate and feels not the sam tourque , i dunno how can i explane , sometimes power comes instantly after that it just pulls ok but not the same ! car is sound ! turbo ok! engine is good to 5700miles, why is this strange feeling ? clutch? spark plugs ? is anyone else experienced like this ? or is it totally normal? 🤦🏼😂

Thank you guys

Fiesta St180 (mp215)

It's called heat soak. You need to upgrade the intercooler.

I own the massive Whoosh V3 which is a steal compared to other brands. However, if you’re not looking to go with some serious mods, you don’t need it. I would suggest the Whoosh V1.

Yes, intercooler. My bad. If you’re doing a lot of starting and stopping, sitting in traffic, less air is being circulated. Having more surface area on an intercooler will help dissipate the heat.

Being a budget hot hatch, Ford skimped on the cooling system on the FiST. Namely the intercooler is basically barely adequate for the stock tune the radiator remained the same as the base Fiesta, but now has the intercooler upfront blocking airflow.

The stock tune’s “overboost” function is basically to limit heatsoak and overheating

Thanks guys! so even if its cold here ? cause in Scotland currently 5-6 degrees

It (the heat soak) should be less (and recover quicker than summer time temps) in ~40*F temps (you were claiming 5*-6* C, correct?), but it will still happen on a very hard WOT pull.

hi, measure it , do not take for granted what people write. Get a cheap obd scanner, maybe forscan and look at the temps in your manifold during driving. If they are high, maybe an intercooler would help. If not, maybe this is not the reason.
