Hi all,

I was wondering if anyone knows any type of engine upgrades that I can do to my Evo X with voiding any warrenty??

Thanks RJ

 

nope.

 

thats really up to your dealer, or the mitsu. shop you take it too.

what ever your thinking about adding ask them first and personally makes sure its 100% good.

my dealer told me as long as whatever cuased the issue being warrantied was not after market related then is should be fine.

 

And you know this was a stock SRT-4 because of.........how? Where you there? Where you the one driving said SRT-4? Do you know this guy personally and seen what's under the hood? Or are you just one of those lamer's that believes everything on the Internet is true? Hmmmmm......I going to let you decide!

 

Why bash the guy and try to make yourself look cool? Do you have any answers to all the questions you asked? If you don't, then doesn't seem like you're in the position to bash anyone

 

Anyway back on topic!!

Seems like Buschur said the EvoX's intercooler is weak. And the Ralliart's is going to be even worse.

My thoughts: How does his analysis compare to the older gen evo intercoolers? I still have yet to change my intercooler because it seems that it is pretty good for stock turbo. I'm sure there were tests done on the older gens and probably showed the stock intercooler needed a better one too, but I wonder if the 8/9 intercooler dissipates heat better than the X's.

 

Thats a good question. I think we can all agree that the stock FMIC was perfect for the stock Turbo, and it definitely was not a limiting factor for the car (Evo VIII). However, with the X intercooler, it appears that we are getting less heat dissipation. One of the things I noticed right away was how much warmer the IC pipes (or hose if you will) were then the hoses in the VIII.

 

I was in the BR dyno bay (42 degrees!) and watched the stock intercooler heat soak (defined as intake temps going up with each pull). With just 3 pulls the temps were higher than I would like to see on my race Evo. The BR front mount was rock steady no increase in intake temps.

 

Wow.....am I the one who is so called "bashing" any other cars on here? Am I the one who made the statement of a "stock" SRT-4 destroying an X? Who cares if the X is not good in a straight line......does that not mean it won't get better in the future?????

This is actually a pretty dumb answer to a really dumb question but, No......I do not have any answers to all the questions I asked since I wasn't the one who made the comment in the first place!

And who is "bashing"? I guess in your opinion I am "bashing"! I am just asking simple question. What I can't ask questions now according to adambl03? Are you some sort of a wanna be mod in disguise trying to bring justice onto your friends? I think the guy can actually stick-up for himself and don't need a "heroes" to make comments for him like you.

Oh and yes I am trying to ask questions to be "cool" that is exactly it.....you nailed it right on the head, please give yourself a star for that one, I need to post questions to be cool. Is that how it is cause I bet your are Super Cool then.

Lastly, I actually didn't see your name in my quote remark so I will disregard your senseless comment toward me.

/end thread jack..........my bad BOOSTEZ!

 

I was wondering about heat soak with the temps that Buschur posted. Especially how that would translate out on a track during the summer. My local track is VIR and it gets very hot during the summer months.

Robi, did you notice any heat soak issues when you've had the X out on a track?

 

You will have the advantage of a lot more air movement then a dyno has though Adam. Granted, the IAT will be higher, and a more efficient IC will be more beneficial. This is an interesting topic because I dont think anyone is testing the IC with the proper amount of air movement to replicate what its really like, so the cooling properties aren't being effectively tested.

 

Yep, definitely much more air movement than a typical dyno setup. I'm just curious since this FMIC is heatsoaking with only a handful of runs on the dyno at 42 degrees. Would seem to not bode well for track season in areas of the country that run over 100 degrees in ambient temps on the track. We'll see soon enough since tracks start opening soon across the country.

You tracked your X recently correct? Did you notice anything? Maybe feel like you were losing power after several laps?

It's amazing how much of a difference the Buschur FMIC made. Either the stock FMIC is really bad (worse than the 8/9) or the Buschur unit is unbelievable (and much better than their offerings for the 8/9). From the info we have so far, seems like the stock FMIC wasn't made to comfortably and safely handle much more than the stock power levels.

 

It was low 50's on my track day, and the only thing I noticed was the car was getting faster as the day went on. Rather, let me clarify this better, the car wasnt pulling timing anymore. The PCM is constantly trying to improve the timing, or so it seems, so as the day went on, it gave me smooth linear power that I didnt have in the beginning. I forgot to bring my laser temp gauge, otherwise I would have checked the IC temp before and after a track session. I will have to do this on my next outing and see.

But, with 50 degree air, moving at 60mph, or greater, its about a negative wind chill, so I dont expect it to get hot. However, on a 90 degree plus day, with high humidity, that could be very different.

I dont buy into a lot of FMIC testing where the car isnt moving. Its not real world analysis, even with a big fan blowing on the front of it. The cooling properties of a car actually moving through air, with different pressure zones being created etc, is FAR higher then a fan blowing on the IC. The only thing the testing really does is show that if you were running your car stationary, this FMIC is better then that one. We need the actual efficiency numbers of a car moving, but that is harder to get.

 

Good to hear about your track day. Interesting how the car seemed to get better as the day went on. That's definitely a good thing. I read your other thread and sounds like you had a blast.

I agree on the FMIC testing on a dyno. Not real world at all. I think we'll get actual efficiency numbers in the coming months when most road courses start to open. One thing I found interesting is how quickly the X's FMIC seems to heatsoak on the dyno when I haven't seen that happen on an 8/9 on the dyno even down here in NC in the summer when it's 100 degrees and 75% humidity.

 

Wow, I just read the results from BR's testing on the stock FMIC. Its crazy how much heat is getting trapped into the thing. I dont know why, but it feels like something is off on it for some reason. How could it possibly be that bad. I think I am going to go do some real world testing tonight, Ill post my results. Wish I could get measurements while I am moving, but thats just not possible right now. Unless I can get that guy from Comedy Centrals American Hotrod to hang off my car for analysis while driving
