Ok, I am having my car tuned by Steve Kan this saturday. I don't know if I'll be able to get my front mount on in time. I plan on running 12 psi on a stock JDM S5 Turbo with ported wastegate. I was wondering, will the factory top mount be able to handle this much boost, or am I going to have to maybe pull an all nighter to get this front mount on. I am going to be doing custom piping, etc...(I have never done this before so I am assuming it will take me a while, especially with the AC and PS still in its place). Maybe since everything is coming down to the wire I am just having a little anxiety trying to get this car ready. Any input/opinion is helpful. By the way it is an S5.

 

I wouldn't put more than 9-10 psi through the stock IC

 

That's what I was thinking, just wanted to get some opinions, maybe some ideas that can help me solve this little dilemma.

 

if you can't get it done in time, put a bag of ice on the IC, that will help with heatsoak. as fo rrunning 12 psi through it there's nothing I can think of that will it from swelling or spliting. how much time do you have before getting it tuned?

 

Saturday, Feb 3. I have all week but I have other things like classes, work, etc. I don't have much free time at all this week.

 

is everthing prefabed or do you need run your own piping?

 

put the time in, 10psi on a stock top mount is not the same as 10psi on a FMIC and will affect the tuning, which is a bad thing. i had to go through this exact same scenario and he made it to the dyno, late but he still made it.

 

yeah, id run some ice or something cold. i mean ambient temp would be ideal, bedcause ice will make it colder than an FMIC will ever get it, but it should do.....
temp correction should do its job. I've always heard to tune at the coldest temperature that you're going to drive in.


maybe just ice the IC between runs and take it off to get heated up when you dyno? i dunno, thats just an idea.

 

I have to fab up my own piping, which will complicate things. I wasn't able to find a piping kit, and didn't have the cash to fork over for a full FMIC kit. So I guess I'm gonna have to ghetto fab it as best as I can.

 

Problem is I have injectors, a fuel pump, and a new turbo to put on too. Let's just say its gonna be a busy week.

 

Well.....I was running 15lb of boost on a stock for a while, but the injectors wasn't big enough and the top mount didn't help either, so I blew rear Apex seal. my suggestion is stay with low boost if u gonna do stock top mount. what ECU and exhaust system are you running?

 

SHE CANT TAKE THE PRESSURE CAPATAIN!

It will handle the pressure fine but why if your going to have a FMIC installed right after you tune it? As soon as you install your front mount your nice new tune will be useless.

 

Stock ECU with an SAFC, Racing Beat turbo back exhaust. I also have a Banzai Racing TID.

 

Pull some all nighters. Even if the Stock intercooler could handle 12psi, it will still need a re-tune after you get your FMIC.

 

Yea I know, but I'd rather have my fuel stuff installed than a front mount. That seems more important. I think I'm just going to be having some late nights.

 

That's what I would do.

 

i would keep the boost low for now until u get the FMIC, rather be safe then sorry....i learned that the hard way, now my engine is under rebuilt...i miss her.

 

we worked 23 hours straight and slept 2 hours then put in another 4-5 before we finished. it was a late night but when tuning you have to have the car in the condition it plans on staying for the tune to be good.

 

Alright, well I'm just going to very carefully plan out a schedule of events for the week. I have to take into effect work and school. As long as I'm not missing classes and work I'll be ok. I can afford a lackluster performance for a week I suppose. Wish me luck!

 

you're having steve kan tune an s-afc?
heh, btw S-AFC sucks because it ***** up your timing, same with a normal fuel cut defenser, so the two of them together are just a timebomb. it works though. i know people who have motors with full exhaust and fmic last a while on s-afcs. but its FAR from ideal

F-Con won't pull your timing, but you need a GCC to tune the RPMs.

Thank god I have an s4 so i can get rtek. YAY!!!! s5's suck! booooooooo

 

I hear that!

 

Yea I was pissed when I found out an rtek wouldn't work out with my car. About the whole SAFC thing, better something than nothing. I'm not going to use a different turbo or anything like that. After this tune, I'll be done with performance stuff, so standalone isn't completely necessary, although it would be nice. Maybe next time around. Well I better get some sleep, I have a long 4 days coming up.

 

Why would you need to retune? Any ECU whether stock or aftermarket will compensate for intake temp.

 

well man i don't know if the tmic will hold 12 psi but im running 11 psi with safcII, RB turbo back and PW, and don't have any problems with the car. although i think i have to add the 720's and the walbro fuel pump.

 

You're running 11 psi of boost on stock 550 injectors?
