Installed my evo 8 front mount [Merged 7-8] ic intercooler fmic

[tlip93tsi]

If anyone out there has tried this; How hard is it to fit an EVO V Intercoler, and how much of a difference did it make?

 

[flinguist]

okay. Where'd you get the O2 housing, and how's the fitment (any interference)? What kind of boost levels are you running?

 

[ShapeGSX]

24 psi to run 116mph, 26psi to run 118mph. 20psi on pump gas. I got the O2 housing from www.122performance.com .

I had to bend the heat shield a little to fit it, but it went on.

ShapeGSX knows his stuff and he is right. During many discussions on this board it seemed that the biggest contributor to boost creep problems with a ported turbo had nothing to do with the turbo itself. Many people were simply installing the turbo on a stock 2G manifold without removing the "gasket saver" step in the collector. THe gasket saver step is the two matching setps on the T-25 and 2G mani that sandwitches a metal sleeve between turbo and the mainfold. This sleeve is referred to as a "gasket saver". On a ported turbo there is no need for this step becaust the matching step on the turbo is removed. Leaving this step diverts the exhaust gasses away from the wastegate opening, this causes the boost creep. Simply porting/grinding this step away will normally fix any boost creep problems.
This is a guess on my part but I would think that removing the divider on the 02 side of the turbo would cause a slight vacuum due to the exhaust passing by the opening farily quickly, thus when the wastegate opens the gasses have an easier time finding their way out the passage. If this is right, which like I said would be a long shot simply because it is a guess, my follow up question would be: In other threads the idea of exhaust gasses pushing against the larger surface area of the 34mm flapper could cause it to open up on the high end of the RPM range, would this be compounded by the removal of that divider on the 02 side?

Oh and the wall isn't there to cause creep, my wall is fully intact and I did exactly what I said in my above post and my boost stays rock steady from spool up to redline. So don't criticize the design of the turbo when many people have had sucess for many years with turbos sharing the same design. Simply because it worked on your car dosn't mean that it is the be all end all and that mitsubishi has been designing their turbos wrong for the past # of years.

The reason you're not getting creep may be because of the relatively high boost level you're running. That range of boost is what people are creeping to. I'm only running 15psig. Have you been able to run at that low of a pressure w/o creeping? By the way 122performance.com is not working.

Shape are you running 11.9 with just Evo 16 and FMIC?!
That's amazing, is that on race gas?

Theres gotta be more under the hood than just that right?

That doesn't mean that 20psi is the only boost level I have ever run. Yes, I have been able to run 16psi.

I also have HKS 264/272 cams, 3" exhaust, a 1G head and intake manifold, the normal little mods, 660cc/min injectors, DSMLink, etc...

It sounds like your still having boost control problems to me. This is from a previous post by you Shape, "While the tubular O2 housing eliminated boost creep, it also made the spike worse because the turbo spooled faster! So I put the ported stocker back on for now.

The solution will ultimately be a better boost controller. The Hallman just can't deal with the boost spike from a quick spooling turbo when you turn up the boost.

You can go ahead and ask me questions here. I hate PMs because the time it takes to write the message is essentially wasted because the audience is only 1 person. I'd rather that the time I take to type in a message be used to benefit everyone."

Since you won't answer PM's, please post when you get your problem solved. Thanks.

 

[ShapeGSX]

I don't run under 20psi, and boost creep isn't as bad in the warm weather, so I still have the stock 2G O2 housing in there.

However, I believe that my boost spike was caused by my Hallman boost controller. My Hallman is around 6 years old. I took it apart for the first time last week. Turns out that the steel ball bearing had worn an oblong channel in the brass. This allowed boost to leak around the ball bearing, which raised the required initial release pressure. Hence the boost spike. So I swapped the valve seat with the other one that comes on the controller (two identical parts on the controller, but only one is used as a valve seat). I will see if that worked tomorrow night when I go to the track.

If it does get rid of the spike, I may put the 2.5" housing back on.

I'll definitely put the 2.5" housing back on for the winter, since the turbo would creep pretty badly in 30 degree weather.

heres the situation....Im on a slight budget and a buddy of mine offerd to sell me his evo 8 fmic for a damn good price. Im just curious if anyone has done this install on a 2g yet? (ive seen installs in a 1g) and does anyone have any suggestions what i should do with the inlet and outlet since they have a curve in them? I was thinking have them cut off and have new ones welded on.

My only goals for right now is a 12sec pass on the 14b and i dont think my stock smic is gonna take me there...

any suggestions would help

 

[blcknspo0ln]

I think your stock SMIC will take you to high high 12's... but only for 2 passes

all the threads on the evo intercooler have had members that said they suck. they're small and i think they're 2" thick [ dont quote me ]

good luck though, because for the right price.. anything is worth while

 

[bigjangin]

IF I got an evo 8 fmic for free and could fabricate my own pipes I would think that its worth it. Otherwise, spend the extra money now for a real intercooler, you'll thank yourself later.

 

[1fast97gsx]

This has been asked SEVERAL times now within the past 2 months. evo8 intercoolers suck ... buy a decent core from somewhere else and then make your custom piping.

 

[BigBADGSX]

serious guys... arent there evo owners running good passes on those ic's right now as we speak? Im not saying i dont belive you guys about the core and what not, but im just wondering if for the right price that ill be happy with what i buy and will i see much of a difference over my stock smic?

also could you guys give me some links or proof about how bad this thing sucks?

thanks

 

[bigjangin]

people have gone deep into the 12's with a stock dsm smic. Doesnt mean its good.

i understand what your trying to say here i understand many have gotten in the 12's with the stock smic but that doesnt mean i will ... i was just curious for some answers. Seriously do you think its not even a slight improvement over the stocker? if so why? and do you have proof??

thanks

 

[bigjangin]

what will the evo 8 fmic cost you? 200, 100, 50? A good aftermarket intercooler core with endtanks costs 200-400 dollars and is better than the evo 8 fmic. You will have to fabricate ic piping with either one. If somehow you could use your stock piping on the evo fmic(not gonna happen) it MIGHT be worth it(like the supra smic). But since you will have to make new piping anyways, why not spend 200-300 more and get a good core instead of shitty stock one.

i have an evo8 ic on my car. i figured hey, if an evo can make 350 whp with it, why can't I? small 16g and the car went 12.6...i/c has nice dimensions, pressure drop isn't too much at all, and it stays cool. works very well for me, and is supposed to flow the same as a small buschur core.

nice man....thanks for the info. You wouldnt happen to be the guy that posted pics of the fmic on your car over at dsmtalk would you??

also could we possibly see some pics of the piping?

thanks

 

[BigBADGSX]

also i forgot to ask if you noticed a difference in performance.... did it improve your quartermile times or mph in the quarter?

thanks

that's me. I have a few pics of the piping, if anyone wants to host them for me, i'd be glad to post.

What is it about the evo i/c that people are complaining about? Is it just not big enough over all? are the endtanks to small? Maybe the inlet/outlets on the tanks to small?

You will want to consider what you ultimately want to do with your car. If you dont plan on going past the 14B, then an evo, or (dare i say it?) a starion w/ redone endtanks might be enough for you. Otherwise, you might be better served waiting and getting the bigger core.

 

[AWDream]

the endtanks are about the size of other i/c's without actually measuring them. inlets and outlets are BOTH 2.5" i/c measures 12" tall, 20" wide, and 3" thick. i can't complain.

 

[Bullitt]

Thats not bad sizing at all IMO. <--- In the end thats what it comes down to. Me? I'd jump on it. But that's 'cause i wont be leaving my 14B behind for a long time, probably until i see jets of oil out my tailpipe.
