Stage 2+ K03 best mods/ expected figures

<< < (14/17) > >>

Beej:
I have put my low torque output down to intercooler also,as besides that, there is no other real reason I can come to given the hardware fitted, unless my engine isn't really healthy.

Just for info, I am running an airtec cooler and I only seen 288 ft lbs on revo 2+, and then 298 on apr 2+. Both agents know what has been fitted/changed, so effectively should have made good overall figures but came shy.

I have lined up a swap plus cash my way for a direct swap of an s3 cooler for my airtec, and we will swap over at the same time, then we shall see how it goes

AJP:
Are these aftermarket coolers simply too big for the k03 then? Is it boost drop, or is that a different thing?

MS1:
It's a spool and low down torque issue. The extra volume that has to be filled with an OEM IC and Forge Twintercooler before pressures goes into the inlet manifold delays boost and creates lag. They're simply too big for ko3 setups. Any ko3, regardless of hardware should at max capacity be running only an S3 IC or uprated version of the S3 IC anything else is counter productive and takes that low to mid range driveabilty away that the ko3 is renowned for.

MS1:
From what research I've done and what Niki said, installing the uprated S3 IC over my OEM+Forge Twintercooler should realise a minimum of 30-40 lbft and maybe even some bhp, although the concensus seems to be split on that one. The upside to this ballache is not having to have the new IC mapped in. If I don't see some sizeable gains from the new IC, the new turbo and the cam chain replacement, I'll shut brick and buy a Fiat

Beej:
I'm just unsure if the airtec I have on is the reason for mine being low, but I keep hearing that s3 coolers are more suited to the ko3 than a larger one.

Mine could be something else, but I don't have anyone who can guide me to start ticking things off in the way of logging etc
