Guest cooljam Posted October 18, 2007 Share Posted October 18, 2007 I'm in the process of going bpu with my standard TT and have just had a front mounted intercooler fitted. Looks great, and will cope with 800bhp. Only problem is that when the turbos used to kick in and everything went backwards rapidly, now doesn't happen! At 4000rpm+ its like I've lost a ton of power. The garage that fitted it said that this is due to the turbo lag created by the massive intercooler. Has anyone heard of this before? Or am I being fed a line?

RobSheffield Posted October 18, 2007 Share Posted October 18, 2007 What intercooler is it? AFAIK, from the very largest to smallest intercoolers, the lag is un-noticable Quote Link to comment Share on other sites More sharing options...
Guest cooljam Posted October 18, 2007 Share Posted October 18, 2007 Thansk for the quick reply It's from a company called XS power, looks great quality. All stainless.

b_have Posted October 18, 2007 Share Posted October 18, 2007 Hope the intercooler isn't stainless! Probably a boost leak from a coupler. Which garage fitted it? Quote Link to comment Share on other sites More sharing options...

Yes you are being Mr Spears At 4000rpm your engine is consuming 100 Ltrs of air per second 3.0Ltrs x (4000rpm/2) /60secs I don't think a few extra litres of intercooler capacity is going to make a noticeable difference. Do you? What make and model is this massive intercooler of yours? Maybe somebody else here has one almost as huge as yours. Quote Link to comment Share on other sites More sharing options...

Guest cooljam Posted October 18, 2007 Share Posted October 18, 2007 Thanks for the advice so far guys. So the theory thus far is a leak in the new intercooler system? Quote Link to comment Share on other sites More sharing options...
Bob Posted October 18, 2007 Share Posted October 18, 2007 You shouldn't see any losses with the fmic in place, I certainly didn't with mine and that was an ebay special. I would say that the garage who fitted it are talking bollocks, and have probably knocked a few hoses / sensors / connections when they were fitting it.

Ian C Posted October 19, 2007 Share Posted October 19, 2007 Either your second turbo isn't coming in, check the FAQs for sequential system problems, or your XS power intercooler can hold air in like a sponge - which has been known to be the case before. -Ian Quote Link to comment Share on other sites More sharing options...

Do you? QUOTE] VE 100%?? Depends where you measure it. As far as the cylinder are concerned it'll be consuming 100 litres per second at whatever pressure. At the airbox it'll be lots more litres at atmospheric pressure. At the intercooler the flow will be somewhere in between. Quote Link to comment Share on other sites More sharing options...
Kranz Posted October 19, 2007 Share Posted October 19, 2007 Do you have a boost guage? What boost are you at full throttle before 4000 rpm and after? I'm guessing that the second turbo isn't boosting, probably caused by a hose coming off an actuator. Quote Link to comment Share on other sites More sharing options...
TRD3000GT Posted October 19, 2007 Share Posted October 19, 2007 Either its a coupling not put on properly and probably leaking under pressure or its the fact its an XS power intercooler. You get what you pay for and the XS units are not known for quality, plenty of people run them but have nothing to compare a good Greddy or Blits or HKS unit with. Arc also make very good intercoolers. Quote Link to comment Share on other sites More sharing options...

paul mac Posted October 19, 2007 Share Posted October 19, 2007 dont listen to all the doom mongers mate unless your intercooler has a HUGE hole in it somewhere, regardless of the quality it will boost exactly the same as any vastly overpriced item with HKS, BLITZ on the front, it sounds very much like you have a hose off, until you sort this be very carefull driving the car as it will now be sucking in unfiltered air, grit, stones, buttends, etc Quote Link to comment Share on other sites More sharing options...
hadyn Posted October 19, 2007 Share Posted October 19, 2007 Sounds like a loose hose to me. Check all your boost pipework... Quote Link to comment Share on other sites More sharing options...

Guest cooljam Posted October 19, 2007 Share Posted October 19, 2007 Thanks to everyone for your suggestions, especially K14 (I'll check the actuator), Ian C for the links and Paul Mac for supporting the people that can't always afford to buy Blitz!
