i used to have TRUST side mounts, did the job ok was runing approx 1bar boost. I just put a front mount on and without any further mods than what i had previously she now boosts to 1.4 bar!!!!! not only that it comes on boost so much quicker and smoother. Oh and 250km/h comes up alot faster now!!!
your side mounts were damaged though. Are you considering before the damage? This means that the trust side mounts had a 6psi greater pressure drop than the front mount. this is a huge difference.
Front mount gets better airflow With pretty much any aftermarket front bar, an FMIC can recieve lots more airflow than side mounts ever could. Hence more cooling efficiency. ie. theres more metal exposed to airflow.There are possible implications of greater pressure drop with side flow tanks (instead of top and bottom). Just wind up more boost! I say.There have been some people raising arguments about overheating. Having had an FMIC for over 2 years now, I can honestly say it does not cause the cooling system any problems. I think those sort of rumours are in the same basket as: "my cousins next door neighbour had a zed, and he had to remove the motor everytime to change spark plugs"go the FMIC !!!
they were not always damaged i didnt notice any difference from when they were not damaged to when they were.
Trust are not the biggest sidemounts ...>> would have been interesting to compare HKS, Stillen ir UAS side mounts.Sounds like Trust side mounts don't flow very well.
I had trust side mounts, then went front mount and I noticed the same difference too. Big difference IMHO :YD
I have a theory......>> That side mounts also benefit from having the car moving, as pockets of low pressure form in the wheel arches behind them and the movement of air under the car assist by "pulling" air through them. This effect cannot be reproduced on a dyno. If anyone has some temp or pressure measuring equipment I'd be more then happy to do some experiments on a dyno and then on the road/track.
i to have trust side mounts, being the only mod before my last dyno i gained an extra 10rwkw on the dyno.I have always believed that no matter how big your side mounts are, a front mount is always better. I have never seen a huge rwkW car or a fast 1/4 mile car with side mounts. "i mean when comparing to cars with a huge fmic"
it depends on the type of FMIC as to whether you are getting the best cooling benefit. Most front mounts have the tanks one above the other. On the Zed, this means that the bottom tank gets more air flow than the top tank, which means the bottom tank is cooling more effciently than the top tank, so one turbo can run on higher boost than the other. Now I dont know what affect this would have on the turbos. The ideal FMIC setup for our cars would be two cooling tanks either side of each other - one on the left and one on the right.
My car was boosting to 1.3bar with > factory side mounts, now with I/C's with three times the volume, it still boosts to 1.3bar.Cheers
Yes Chilli But did you measure the air temp of the outlet at Full boost then do the same for the New IC>And even then you would need almost a data logger to do some real testing. CheersAnthony
I got same results Chilli I also changed over to the UAS side mounts, still stayed at 1.3 bar. Definately runs a bit stronger on hotter days now though. Just changing the intercooler shouldnt make the boost go up by 6psi unless something was seriously wrong with the old one.
Sorry guys... Ive got a front mount and love it, but your deluding yourselves if you think its an improvement over good sidemounts. Maybe there is an issue with trust intercoolers, though I cant see any reason for it, but there is just no way to get LESS pressure drop across a front mount intercooler. Plus it has its own inherant design defect with it feeding the wrong side of the engine not to mention problems with unequal cooling. Any thought that boost comes on faster and smoother is just imaginary.
