I have a Greddy FMIC V-spec (which as per Greddy, it is suppose to be used with the twins only or with 15 psi or less). I swap to single some time ago and did 430 whp at 19 psi; I have even reach 26 psi sometimes on track... Though, i'm stiil w/the V-spec Greddy IC. I was wondering it might be a good idea to upgrade it based on the Greddy's concern. Though, I haven't had a chance to monitor the Intake temperature to chk how the Greddy is working with the current set-up. I have read that a properly sized IC should be working between 65-70 ēC under load, not exceeding it. Has anyone played or known about the IC/size/temperature issues? I will chk my temperatures next week and let you know...

In case i need to upgrade the IC.... Has anyone tried those bar & plate IC's sold on eBay? Anyone with pictures of this or a similar FMIC installed (3" horizontal inlet/outlet layout)?

thx!

65-70C is much too high for a FMIC system, I would say. If would not want to see see AIT's more than 50C+. Anything higher, and my Haltech starts pulling timing etc.

I have a Spearco (Turbonetics) core 20"x8"x3". My intake temps are usually around 35C to 45C between 15-18 psi on my SR KKK turbo. This is on an average summer day (85F).

35-45ēC under load? that core is similar to mine..... how much hp your are geting?

i did my search a found some answers about the universal IC fitment...it's not that bad...

what about the IC temperature references, anybody else??

Can you convert to us SAE folks in F?

I was tuning a pair of cars in CZ.
Ambients down to about 10C.
The GReddy V-Spec / GT35R on an FC3S up to 15psi was running about 110F on the Haltech.
Another FC3S with a custom stock twin TMIC cores in parallel, H-trim hybrid running up to 15psi was running about the same - 110F - 115F on the Haltech.

I punched those numbers on an online conversion table...
110F = ~43C
115F = ~46F

The temps i read about a similar set-up of my FD (T3/62-1 2row FMIC) under FULL load were 149-158ēF @ 85-90 ēF ambient.

ok...

evils numbers are
95-113 ēF @ 85ēF ambient, I think that's under normal driving conditions...

Ted numbers are
110-115ēF @ 50ēF


mmmmmmmm..... to many variables or something wrong here///


anyone else?

thx!

I would say there are just too many variables.

My FMIC is bar and plate.
I don't have a CAI, for instance. Filter is directly on the turbo.
Also, on my FC, I have the intercooler piping running near the UIM, that will hurt temps a bit.
I would assume that someone that is pushing their turbo past its efficience range, and thus puts even more stress on his intercooler would see different temps, etc etc.

Here is a 14 psi datalog of mine, with intake temps. It was about low 20C's (70-80F) out that night.

I was going to start a new thread related to the Ebay intercooler but all these great minds seem to already be on this thread..if you dont mind on a side note..im looking for a recommendation on the size of intercooler I should use. I'll be running the stock rebuilt HT18 at about 9 lbs of boost 15 at max. I was looking at the 24X12X3 they were offering on ebay, but is it too big?, should I stick to the smaller one sized 24X7X3, with 2.75 inlet sizing. Eventually ill be swapping to a larger turbo but im using this as a daily driver for now. The motor is JDM block, ported and pinned with most likely Aviation apex seals or atkins seals. using a HKS EVC V for boost control, HKS VPC, and a Tial blow off valve, and more gauges than Ghandi to keeps tabs on everything (slightly paranoid) your knowledge is appreciated...thanks..

If you're talking bar-n-plate, I don't have any direct experience with any of them as of this moment.

We do have two projects "in the works".
One is using the 24" x 12" x 4" "XXL" eBay core on a 20B.
I'll be using the 24" x 12" x 3" "XL" eBay core on my 13BT.
Don't expect this to be anytime soon.
There's a lot of things that need to fall into place before these projects hit the dyno.
The 20B will probably be up and running first.
Hopefully both will be running by the end of the year...

one of the local guys here got the 4" deep one for his HBP setup.
im rocking the 3" deep one.

there is another local guy that has been running the 3" deep one for months. I was inpressed by it and got the same one.

the ones we got were from ssautochrome. they are in NC and ship to me in charlotte in one day. I got mine for 180 shipped. Welds look great... im sure it is plenty for what im using it for.

I plan to post my whole setup... details, pics and dyno sheet right after tuning.

Sorry if this is a bit off topic, but does this intercooler seem pretty decent for my 350rwhp setup? It's a bnr stage 3 turbo @ 17psi once I get the fmic. Also I may be running alc/water inj.

http://cgi.ebay.com/ebaymotors/30x7x...QQcmdZViewItem

Anyone have any info on this intercooler? pos? great piece? etc..if not I'll end up buying the same one as Evilrotor.

AImec Racing

ok guys, I have some numbers...

just did a test and here are my resuls:


Set-up
'94 FD 430whp @19 psi (3rd gear) 93 pump gas, 62-1/T3. Greddy 2-Row FMIC, Street port... currently at 23 psi


Fuction Engine Temp. Ambient Temp. Intake Temp.
Idle 176 ēF 87 ēF 140 ēF
Cruse 180 ēF 87 ēF 127 ēF
WOT 186 ēF 87 ēF 136 ēF

I was able to run just 2 passes under full load at 4th gear before reading the final results which are the WOT's... as expected temp was increasing everytime so I would say it would probably reach 140 -145 ēF under full load with a few more passes...

If i compare this with your numbers, i might need the 3 row... but would like to get mora data before making any move ....

i would said it will work,,, at 350whp that would be fine...best if front mounted....anyways, its way better than the stock, but keep chk the thread to see if some numbers come around....

hmmm a 62-1/t3 on a fd. you fd guys and your t3 hot sides confuse me.

I wasn't talking about the greddy front mount, it's bigger than I would like. Look at the link I posted ^

BoostedRex

Nick, he did look at what you posted and agreed. He has the GReddy on his car. Just wanted to clarify.

AImec Racing

is not that confusing,,,, i'll explain you....

If any given sunday... you find a 500 whp NA vette next to you (yes...NA) and after the eye contact both down shift to 2ng gear and in less than a second you are ahead... it means that there is virtually NO LAG with you turbo...nothing against big turbo exhausts... basically is just about what you want, i know fd's will flow enough to spool big turbos, but I'll rather spool faster and not loose a single race in street


now back to IC's... any other numbers? …. do i need to upgrade ???

AImec Racing

correct!

I'm also looking at one of those bar n' plate ICs for my GT42R setup, I'm looking at the 4" version. I'm still holding out for some confirmation that bar n' plate is legit, as I have zero exp w/ the variety.

kabooski

Well if you have enough money for a GT42R R=$Bling $Bling
Then don't CHEAP out on the IC
get a AS-1019 Intercooler from Precision Turbo
27.0"L x 10.5"H x 3.5"D (core) supports 825HP +

its around $550
on Honda-Tech

Great link of IC's found in a neighbored thread, cleared most of my questions...

though, i still would like to see more real data from your rides...

YayeR

kabooski,

thanks for the reference.

smokeAcop

a friend of mine got the 4" thick version and has ran a 9.9 on it, so im sure it will be more then enough for your power output.
