Toby - In your opinion if you are still runing a normal CT9 like myself albeit with full decat, exhaust, filter, iridiums, RRFPR, Walbro etc would you say the advantages of a FMIC are not enough to justify the cost? Even the £300ish required for an AB88 'cooler is beyond me at the moment but it was on my wish list! Currently I don't intend to change/hybridise the turbo but as Im running 0.9bar was wondering whether the extra heat being generated was meaning I was doing damage by no running a FMIC or better mani?
Hi Mike,
I would say if you want to run more than 1 bar then yeah either get a good FMIC or something like the ARC, wrap the throttle body side pipes with heat reflective material as well ,there are quite a few different aspects you can change to aid cooler charge temps.
Raise the rear of the bonnet which will help rid a lot of heat, use a good manifold with high flow rates like ours and concentrate on inlet temps. The stock EFI pipe runs right over the manifold which will contribute to some of the heat the CT9 sees, fine on stock boost, not when you go over.
If you plan to stay under fuel cut then the stock top mount will be fine, a lot of Jap owners use to run the K24 bolt on kits with stock manifold and stock top mount so you won't need to worry about a FMIC until you begin to extract full potential from the hair dryer.
Thanks,
