Today during an annual autocross event my engine all of a sudden lost power and shut off, after an extreme panic I realized one of the intercooler hoses had popped off, thankfully nothing flew up into the engine while it was separated, however I am upgrading to some heavy duty clamps and I recommend those with tunes and/or old and rusty stock clamps to do the same!<p><br> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/embeer.gif" BORDER="0">

Re: PSA: Aftermarket Intercoolers (PasS40ion)

T-bolt clamps are a must for high pressure turbo setups. The factory and any regular screw clamps are garbage. Glad to hear your car is ok.

Re: (PasS40ion)

Damn, thats why i was sayin get a 1/4" oversized. Send them back they will refund you/exchange.

Well the diameter on the stock IC is 2 1/8th and I went by the size Bell said they use on their instruction manual <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0"> so I assumed 2.5" would be big enough maybe someone with bell can comment did they supply the wrong size? or is 2.5" just too small.<p>I bought four from Ebay 4 for $12 shipped doubt the seller will take returns, but it is ridiculous ATP charges $15 shipping minimum for clamps!! Hopefully the ones I have ordered have a large enough diameter otherwise at least someone else won't make the same mistake clamp sizes really haven't been discussed on the board at all.<br>

Re: (PasS40ion)

The rubber couplers are that thick huh. Must be time to upgrade to silicone couplers and new clamps <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0">

Silicone is tempting but I don't like the fact that the Samco hoses increases the diameter so much, I realize the need for an extra inch when it comes to exhaust piping but when it comes to air going to the engine a larger diameter will equal=more volume=less pressure= which will result in loss of lower band power, unless my thinking is completely wrong. <p>If the silicone hoses were the same size as the OEM ones I can see how better airflow and smoother internals can lead to more power...

Re: (PasS40ion)

Well the pressure isnt affected really, if your tune is set for 15psi then you will build 15psi whether the volume is smaller or larger... the key is larger volume of air which allows for more fuel to be added in turn making more power. Just adding these couplers or increasing volume in general wont do anything unless you commensate with fuel to increase power requiring a tune. Smooth couplers instead of ribbed merely allow for less turbulance which in a high output situation can cause loss of power.<br><BR><BR>

I think it's minimal but maybe it's like when you install an after market intake sometimes you sacrifice low end for mid range-high end?

Re: (PasS40ion)

Id be curious as to see how much this kit really does increase volume because i cant see it being much. I see what your saying about lag but you guys seem to be sensitive to it haha. Take you for a ride in my turbo honda and let you see what retarded lag feels like lol.

Re: (ForceFed Motorsports)

&pagehaha whiplash lag?<p>And according to this thread <A HREF="http://forums.swedespeed.com/zerothread?id=103708=1" TARGET="_blank">http://forums.swedespeed.com/z...age=1</A> at atleast one point in the tubing it increases it from 2" to 2.5" I guess I am sensitive because I love the fact that I have barely no turbo lag and the turbo kicks in so fast after riding in a friend's gti. And I would like to keep it that way lol. Which is also why I would go with the gt28 if I upgraded turbos, less peak power but it just kicks in right away just like NA. <br> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: (PasS40ion)

It could make more of a difference with a volvo since it seems that the majority of the intercooler piping is hoses not actual piping lol. The effects that ive messed with is changing diameter hot pipes to the intercooler on numerous honda setups. From the turbo a 2" to 3" pipe makes a substantial difference in lag and also peak power so yeah i know what your saying it can make a difference thats for sure.

Your tune doesn't target a specific PSI, it targets a specific volume of air at a given RPM.<p>So, PSI will vary based on altitude, temperature, etc. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">
