RedM Posted September 30, 2005 Share Posted September 30, 2005 Up here the weather has really switched in the last week or so. It's a lot cooler in the mornings and evenings and I'm finding that the car seems more responsive and the turbos seem louder and more, I dunno, like they are spinning easier or faster. Is this okay or typical? I've read some stuff about cool air but it all got a bit technical for me and I went off to look at porn. Quote Link to comment Share on other sites More sharing options...
michael Posted September 30, 2005 Share Posted September 30, 2005 Perfectly normal, just wait until it gets really cold, that's when the fun starts (but you can't take advantage of it because the roads are icy ) Quote Link to comment Share on other sites More sharing options...
Nic Posted October 1, 2005 Share Posted October 1, 2005 Is this okay or typical? I've read some stuff about cool air but it all got a bit technical for me and I went off to look at porn. Quite normal, I get a big difference in performance between 40C summer temps and 4C winter temps here. Put VERY simply Cooler air = more dense, more dense = more oxygen, more oxygen = bigger bang, bigger bang = more power. edit: [i'm talking bollox]The oxygen sensor will also tell the ECU that slightly more fuel is required to keep the mixture correct, which also accounts for the extra power.[/i'm taking bollox] Quote Link to comment Share on other sites More sharing options...
lpher Posted October 1, 2005 Share Posted October 1, 2005 40C summer temps and 4C winter temps here. Thats unfair! More like 30c and -20c 'round these parts! And...you could say ive noticed this effect too Especially with my IC being kinda shot Quote Link to comment Share on other sites More sharing options...
Getrag Posted October 1, 2005 Share Posted October 1, 2005 So...does a good FMIC give you this effect all the time? Or close to this effect all the time? Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted October 1, 2005 Share Posted October 1, 2005 This winter will be the first time i have had a turbo'd car, for the record say at 3'c what kind of power gain will you get it cant be anymore than 3 bhp can it ?? Cos i really did not notice that much of a diffrence from my last car (02 plate civic type r) Quote Link to comment Share on other sites More sharing options...

Cos i really did not notice that much of a diffrence from my last car (02 plate civic type r) LOADS more than 3bhp, with the temp differences I get here, I would estimate around 10% increase in power, between coldest and hotest days, possibly even more than that. ps. that's with HKS R-Type FMIC fitted on stock turbos Quote Link to comment Share on other sites More sharing options...
Ian C Posted October 1, 2005 Share Posted October 1, 2005 The oxygen sensor will also tell the ECU that slightly more fuel is required to keep the mixture correct, which also accounts for the extra power. The intake air temperature sensor does that actually Nic -Ian Quote Link to comment Share on other sites More sharing options...
terribleturner Posted October 1, 2005 Share Posted October 1, 2005 Keep forgetting to turn the BC down. If i hit boost cut once more i'm gonna head butt the steering wheel (and probably not on purpose either ) Quote Link to comment Share on other sites More sharing options...
paul mac Posted October 1, 2005 Share Posted October 1, 2005 took mine down the local bypass today and a prat in crappy BM had a go and the car was flying (i did'nt even have the boost controller on) hot weather really does blunt the performance of a turbo car even with a fmic, happy days ahead Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted October 1, 2005 Share Posted October 1, 2005 LOADS more than 3bhp, with the temp differences I get here, I would estimate around 10% increase in power, between coldest and hotest days, possibly even more than that. Deffo, I certainly noticed a huge difference in power when I was in Germany, the first day it was scortching, maybe around 33oC and the car felt gutless, then it rained overnight and the temps were in the 20s and it felt so much nicer Quote Link to comment Share on other sites More sharing options...
JamesG Posted October 1, 2005 Share Posted October 1, 2005 I notice a big difference in throttle response when it's cold. I imagine that's partly because I have an aftermarket cone air filter. The max boost pressure also gets higher in cold weather, so I've turned my boost controller down a couple of times in the last week to keep it at 1.2 bar.
