Lets Talk d-series

[beeza]

Not sure..maybe cause it's the y4?..

[TheSaint]

neither my Dc2 or EG8 had a speed limiter?
wierd - my money would bet that its an auto thing

[beeza]

Yeah its definately there but not all the time as I have hit 200 a few times,weird alright.

It seems like those times the car was going hard and the ecu had learnt my driving and kept going.

Like,if I try it now,I dont know if it will be limited to 160,as it's not everyday I test it!

Probably an auto thing.

It's no problem at all and it has never been an issue at all,so that's good.

almost the same kit as me with the black wrinkle piping etc
Fujita have a very good quality pod over other brands thats one thing i would have to agree on

i have to admit tho - the gain did not feel as dramatic in terms of response/power/sound when i put it on my D15b7 as when i put it on my B18c2
but i felt more of a difference with the whale type intake on my D-series - but when i put the whale type on my B18c2 it was the opposite
strange - the unit i put on the Dc2 was a stainless tube - and the one on the D-series is black wrinkle - would this affect performance/sound?

this is mine ...

Having it painted should not affect the performance as far as im aware. I just like black so i painted mine as i couldnt order a black version. Sound is irrelevant when it comes to performace, having a louder intake doesnt make you go faster it just makes you feel like your going faster.

That looks to be a different chassis than ek? the design of the bumper ect may give you different results. I.e. if the grill in the bumper allows enough air in for the pod to breathe. Ek pre-face has an adequate path via the front grill and the facelift can have a direct feed via the fog light cutouts in the bumper.

mine is a 93' EG8 sedan - i have a feed hose from the opening in the front bumper
and i have a louvered vent directly under the pod directing air from the bottom/front of the car
im quite aware that sound does not effect performance - its more of a curiousity

my Dc2 just had all the stock mouldings - so less airflow
but the induction pipe goes down the gap just in front of the engine mount on Dc2
where on the EG it goes through the hole for the resonator on the stock air box

mine isnt just painted black its a limited run 'wrinkle black' version of the intake from factory
the inside and outside diameters are wrinkled/dinted - like its been sandblasted or something
it also feels like theres an extra layer of insulation or something on the piping
the Dc2 kit had larger diameter piping but it was thinner and standard stainless material/finish

as for the color some may argue that having a reflective/shiny intake would reflect heat better
but i dont know if it would really make that much of a difference with cold air flowing through it
maybe for heat sheilding it would make more of a difference

[TbM]

If there is wrinkle paint on the inside too then it may effect the way the air travels through the pipe, may have also reduced the diameter of the pipe depending on how thick the paint is. Having a painted pipe should help avoid absorbing heat from the engine bay but once it was heated it would be harder to cool down. it wouldnt be a noticable difference, you would be better off heat wrapping it or using some sort of insulating foam/rubber if you wanted to keep the pipe cool .
are you sure the dc2 one was steel? IIRC most of the intakes ive seen are made from polished T6061 aluminium which absorbs and disapates heat quite quickly and looks somewhat like stainless steel.

What size piping is the kit for the eg? 2.5 , 2.75 or 3 inch?

Regards,
I dont even.....

[TheSaint]

not sure about the piping material on the Dc2 one - it was over 4 years ago
had it on the car for 1 day than the car got written off and i spent 12 months in a wheelchair + another 12 learning to walk again

as for the EG one - just got all 4 wisdom teeth taken out so i will have to go out and measure it wen im feeling a bit better lol

my guess would be that the Dc2 one was 2.5 and the EG one is 2.25
but ill measure it when i can and let you know - ill also see if the wrinkle is on the inside diameter as well

[TbM]

If it was a genuine fujita kit for the dc2 it almost be willing to bet my left nut it was T6061 aluminium alloy as thats the only thing ive seen fujita make intakes out of(painted ones may differ). heres mine before i painted it as an example.

Pretty much looks like stainless steel.

Ill see if i can google the diameter of the fujita eg intake when i have some free time, just finished work so gonna play some ACR and relax, if the d15 is similar to the stock d16y4 in the ek the best diameter is supposedly 2.5 inch.

I must of misread your post i thought you said the inside was wrinkle painted. just quickly read it and posted a reply at work. the inside of my pipe definately doesnt have any wrinkles/dints. I was under the impression you want the internals of your intake piping to be smooth, one would assume having the inside wrinkled could cause unwanted turbulance.

ACR = Win

[TheSaint]

im not sure about the inside diameter
ill go check when im feeling a bit better

the pic above is the finish that my Dc2 one was
most likely ally like you said

if the d15 is similar to the stock d16y4 in the ek the best diameter is supposedly 2.5 inch.

fark well i got a intake for really cheap from my mate

i just measured it its a 3 inch...

edit: i havent gun it or anything cos no insurance on my car atm, only went a lap around the block, its very responsive on normal driving.

just i think this might eat a lot of fuel ?

[TbM]

The difference between 2.5 to 3 inch will be quite small, having a larger pipe of the same design usually reduce response and moves the power further up the rpm range compared to the smaller diameter pipe.

When i installed the fujita CAI on my car it did seem to use a little bit more fuel but i do drive it harder now so it could just be my right foot more than the intake.

[viinnh]

really mine was diffrent man just took it for a drive gear 1

0-60 is normally first gear
0-40 was way faster and 40-60 in first was just a little faster or the same

car was fully warmed up
