my egt`s have gone from a bad 1050deg`s with old stock intercooler to 900 degree`s with fmic

 

also the titan motorsport 9 second drag car uses stock bumper with big fmic, and seen another 8+ second supra with stock bumper and fmic it also had a stock radiator too. they all tend to change to fluidyne aftermarket radiators too.

suppose prevention is a good thing its always best to try keep cooling temps down. water injection sounds good along with a fmic.

the jap cars need some sort of bonnet sccop to get cool air in engine. nobody wants to see an engine go south.

 

we need some sort of list of mods that we can do for cooling and fueling mods. i cant think of any other mods to do but cooling and fueling mods.

 

stuff like gearbox coolers and oil coolers.

 

what other cooling mods can you do for us?

 

can you not get a small panel to direct air up between radiator and fmic.

what sort of age/mileage cars are we generally 'killing' on this site...

 

Mine is a 94 RZ with just over 50kmiles... The SMIC is very crumbly but looks generally in good nick.

 

A HKS S-type was on my list to get done when the turbo's went but after working out the damage to wallet after the rebuild it was out of my range....... and still is..... :confused:

 

If the car still hasnt sold in a while and i decide to keep it.... it WILL be getting......

 

FMIC

water Injection

bigger injectors

 

as a start...

Chris, I don't want one RIGHT THIS MINUTE, but, if/when I get some

more cash I will NOT be fitting an FMIC so your uprated one sounds

ideal ! !

 

I like my active spoiler THANKS:sly: AND I REALLY like a nice

uninterupted flow of air to my RADIATOR..... OH YES ! ! !

 

(I've NEVER liked the idea of 'covering ' the radiator up ! ! !:conf: )

 

Unless I blow my Soop up / go bankrupt and have to sell / 'cop-it'

 

then you can defo put me on the 'future-buyer' list ! ! !

Chris/Dude, before you start selling these you really should publish temperature drops across the IC so these guys can get an idea of efficiency before parting with their hard earned cash. I know what the HKS R type can achieve which is darn impressive. I will also check a stock core, then if you both publish your findings we can compare.

mmmmm..... well I know Toyota made a fair job of the Soop, and,

they are among the better of the Manufacturers as regarding

design/performance etc, but, I doubt they bothered TOO much

with the actual efficiency of the standard IC !

 

I bet ANYONE could copy and BETTER the original !

 

[ the only problem is being bothered/able to do so.....

I know Chris' IC may NOT be the SUPER-FANDABBY-DOZY best

item on the planet but as long as it's AS good as the original

AND a lot cheaper - I haven't priced a standard one yet ? - then

I'll have to go for it ]

 

Does ANYONE make another 'standard-fit' IC for the mkIV ? ?:conf:

 

FatS.

 

[oh, sorry, AND EASY TO FIT "for MORONS"....... "for ME ":p ]

Steve - you don;t half wade in m8!

 

Just chill a minute - and I suppose the 9 second Titan hates to cover up it's radiator too! LOL!

 

Toyo did a great job - problem is - we keep modifying the original! And most are getting on now (as I know only too well - bit crumbly meeself!)

 

Chris' is, I am sure, an excellent piece of kit and will provide an excellent alternative to the SMIC

 

It will be very interesting to see what kind of figures Dudes FMIC comes up with - but having seen the core and fitting etc it's got to be a great alternative to the HKS - and will handle the extra boost with ease

 

You pays your money...

ARC INTERCOOLER are suppose to be very good, better than a HKS Type R.......(numerous places advice)

Type S(smaller one)- 1200 quid

Type R drag spec-massive only really big hp cars use, as 'drag spec'

 

 

Temp needle never moves from the middle, even on hour long bursts....but this might not have much value until you actually test the inlet air's temprature...as Dude to show proper readings...will find out inlet temp's today from Nana, and compare with others..

The trouble is, everyone with a big IC says "Wow it's great" and there is very little actualy data available. If you use a thermocouple to measure external air temp, temp at the the turbo exit, and temp at the throttle body inlet, you can work out a % efficiency and compare between different IC's.

but wouldnt the temp gauge on the dash show a hot engine cos of a crap intercooler?

 

or is that showing a different temperature?????

 

Faith, thats your water temp of the water circulatuing round your engine, I doubt that has any idea how hot your IC is getting.

Just measured mine, 1.1 bar boost, 26C ambient, I got 37C at the throttle body at full throttle. Result! I run a skyline GTR intercooler, hardpipes, and a hybrid turbo. Totally irrelevant to all you guys but it makes me feel better :D

Steve, I am not trying to knock Chris/Dude at all. I would have thought that Toyota did a pretty good job on intercooler efficiency as they were designed for the JDM market & their ambient temps are much higher than ours. Also Toyota always over engineer. As far as SMIC's the stock unit is as efficient as the GReddy, but people switch to the Greddy due to it's additional strength for higher boost. The plastic Toyota ones have been known to split but not at the kind of boost most of us are running. I also know of one guy in Canada running a T88 on a stock side mount with WI.

 

I am sure both the guys have done their homework. Cooler charge temps are a good thing & if they are more efficient than stock then brilliant.
