new tires brakes body work for dents and scratches to get fixed car will be almost flawless 46000 miles on it looking to sell by end of next month

 

Its not a good idea to run different kinds of pads on the same rotors. Google it.

I only run the fronts. HP+ in the rear.

 

Anyone ever heard of an issue with the tc's regaurding the maf and the car starting but not stayin running? The guy I was helping heard a backfire then the car went into safe mode, we unhooked the maf and it runs, also he bought another maf sensor and it did the same thing, any ideas? His car only has 2400 miles on it and its an 09, he threw a code for the maf sensor as well

 

Backfire or charge piping blew off? Check it. I bet it's his problem. I've had it happen a billion times.

 

Right my first thought too, but no, they seemed legit not off nor any cracks I cud see, and all lines seemed to be good as well

 

Ive heard of this problem a couple of times while I was trolling the LNF page...check the plastic on the sides of the intercooler. From what I hear they suck some major c*ck

Edit: the stock intercooler anyway..

 

Damn u smack a deer? Or stationary object? Nice rims as well what size r they?

 

Didn't go in depth with the end tanks cuz of the shroud underneath, have to take it off, he's takin it to a dealer tomoro and will see what they say everything looked and seemed legit, I will most certainly fill ya guyz in on the cause, ya the end tanks are garbage frikken plastic, still blows my mind they would go so cheap on having plastic pipes and end tanks on the system

 

Most of the interior on these cars is cheap crappy plastic, so why are you surprised when other components are?

 

Well guys i am a plastic process engineer, They didnt really go cheap on the plastic in the engine bay. The end tanks on the intercooler, the intercooler is made of PA with Glass fill of probably at least 30%. It is extreamly strong, but brittle. The stress strain curve looks like a mountain peek, its strong then just breaks off. I dont think they engineered the parts correctly. It usually isnt the plastics fault its the part designers. The part has to be designed correctly to function correctly in the plastic world theres no room for error.

 

Haha well said. Its usually a failure due to design, but I'm going to say that their design wasn't really that bad on these intercooler end tanks. They used brittle plastic because they never expected it to impact the ground. Unfortunately with lowered cars it usually does and thats why its likely to fail. Lol, I like to think of it not as a failure due to design, but a failure due to improper end use. Jim, you ever hear of this plastic called Ertalyte? I've been working a little bit with it in some part designs at work. Its an interesting plastic to say the least.

 

No i actually havent. We deal mostly with Acetal, PC/PBT blend, Nylons, PE and PP. Thats about it. Of course "its not the designers fault" lol. damn designers. the process guys always get the bad rap when their **** dosent work. But yes youre right this case they used a good plastic but the application was wrong, theres so much that can go wrong with plastics everything has to be just right.

 

Do you have a link to the Data sheet for it? or the manufacture?

 

Not that I found out now about the end tanks now, but sure was shocked when I did, yes jim and arron I know the plastic is tuff

 

Wow that erytalyte is very interesting. It seems like it might not be a bad material for some of our chains. Right now we are using Nylon 66 with Melt resistant additive packages for our high temperature apps. It would be interesting to see how this would perform since they claim low coefficient of friction and high operation temps. We make chain so strength, friction, and wear are huge for us and dimensional stability is always a plus.

 

Haha you beat me to it, but yeah its an interesting plastic. It has strength and operating temps closer to steel than most other plastics, yet its low friction. They only downfall for most applications is that its brittle, but in the applications that we are using it the brittleness is actually one of the main reasons we're using it.

 

Other cars have plastic end tanks on the car from the factory. Pretty sure my MKV GLI had plastic end tanks, I know the MKIV Supra side mount intercooler has plastic end tanks.

 

What do you Design aaron?

 

should be renamed... CSS Engineering Thread..

 

Lol, says an engineer to be.

Defensive military vehicles.

 

Thats awesome, that would be a dream job for me. Here is what i do or my company anyways: Food & Beverage

 

Ya that sucks that most come factory with plastic tanks on ridiculous! Arron do u kno how much the flash was for the gms1? Also the guy with issues blew his intercooler thanks guyz, ty can u post the link again for the RA track day

 

That is why I am changing my car up a little this year.

 

 

Just saying my cars up for the car of the month pull this month, go vote for which car you all thinks best. Thanks for voting no matter whom your vote is for. Thanks everyone
