JAGR33 Posted June 21, 2005 Share Posted June 21, 2005 Why are you so attached to that set of engine pipes? You are compromising the whole system because of it. I would sell them and buy the CES turbo to cat system, if money is the reason you want to keep them. If money is not an issue go the Trust, they are a true work of art.Either way I can asure you that the results will be worth it. SK - what sort of improvement will the Trust front/dump pipe combo make over the standard dumps if your running bigger turbos??

Sydneykid Posted June 21, 2005 Share Posted June 21, 2005 SK - what sort of improvement will the Trust front/dump pipe combo make over the standard dumps if your running bigger turbos?? Well I have seen a 25 rwkw increase and 400 rpm earlier boost build from an R32GTR running R34GTR (ball bearing) N1 turbos. That's with no boost increase, in fact there was a boost decrease as it obviously removed a restriction. And no extensivel re-tuning, just a couple of minor fuel and ignition timing changes. More advance as the boost was lower. This improved the response measurably, which is a welcome bonus.

Not so much interested in more power, but 400rpm earlier boost build???? I LIKE!! Do you reckon this will be the case with Truck (Trust) turbos??? Being bush bearing, they may not respond aswell as the N1 ball bearing turbos??

Ryan1200 Posted June 21, 2005 Share Posted June 21, 2005 CES do a so called hks copy but also a long wastegated version similar to the trust ones. It requires different front pipe obviously.

It requires different front pipe obviously. *cough* I believe CES calls these their "competition pipes" to distinguish them from the HKS-ripoff version they also sell (as pictured above) LW. PS.

paulR32gtr Posted June 25, 2005 Share Posted June 25, 2005 How about the flex join? Is that important in GTR's as most aftermarket jobbies have that flex for the front turbo.

lwells Posted June 25, 2005 Share Posted June 25, 2005 How about the flex join? Is that important in GTR's as most aftermarket jobbies have that flex for the front turbo. IMHO -- and I have no evidence to back this up -- I think the flex joint is a very good idea. Anything the reduces the amount of movement exerted on "fixed" parts (ie. the turbos) is a good thing. Whilst the exhaust is mounted with rubber grommets to allow it to move about, the turbos aren't. Transmitting all that vibration without a dampening effect doesn't seem like a good idea IMHO. williamsf1 said that the trust units he got recently had a flex joint, even though the press photos don't show one.

paulR32gtr Posted June 25, 2005 Share Posted June 25, 2005 Yeah - would be a pain to get a crack in the pipe after completing the pr!ck of a job to get them on. I am going in on the group buy for the trust front pipes - was thinking if they dont come with the flex join I will just get one put in.

williamsf1 Posted June 26, 2005 Share Posted June 26, 2005 I still think that as internal wastegated turbos go, the TRUST units are by far the best (may not be the cheapest) and as it is a biatch of a job, doing it once seems to save money in the long run....

«Cyph3r» Posted June 28, 2005 Author Share Posted June 28, 2005 ahhh .... got my car finally and guess what, after all that it has mines dumps allready.... i think i'll keep them for the time being until i have done a few other things to the car i would like to first and that will take priority to these at this stage, plus i'd like to see what power i get with these and the rest of the system and then if i can, compare it to a gtr with trust front and n1s and compare them. will keep the trust pipes in mind though. thanks everyone for your opinions and advice.

Marko R1 Posted June 28, 2005 Share Posted June 28, 2005 i was in a position to buy either the hks dumps or the trust long dumps as i was also upgrading the exhaust... i was informed that the long wastegate pipe on the trust systems create more lag, now i dont know how true this is although i was told by a dyno tuner that works on a lot of gtr's i bought the x-force (hks copies) for only $450 for the pair via crd in sydney. pls don't take as gospel Link to comment https://www.sau.com.au/forums/topic/77473-which-dumpextension-pipes-to-buy-for-bnr32/page/2/#findComment-1435664 Share on other sites More sharing options...
lwells Posted June 28, 2005 Share Posted June 28, 2005 More lag? I would love to hear what the theory behind that is? I have heard it mentioned that in very high power applications that a (larger) non-split pipe design has some advantages Regardless, the vast majority of people will never get anywhere near those power levels.
