Nic Posted April 7, 2005 Share Posted April 7, 2005 Any opinions on this at all? I very definately dont disagree with you TLicense, i know you know your stuff, and i do know Ti is brittle. Just wondered if anyone had experience of Ti system cracking on a Supra? im tempted to agree with bobbeh when he says I have an ARC Titanium exhaust and it has cracked twice. First time was on the bend where it had grounded, fixed it and added a thick skid plate on the bend. The second time was again as a result of grounding the exhaust, but this time one of the brackets cracked around where it was welded to the pipe. The wall thickness of the piping used on titanium exhausts is very thin (mine is 1-2mm) I believe this is why mine crack when it was hit. If your titanium exhaust does crack, it can be an issue as it needs specialist welding gear to fix. Had mine welded for me by a friend who is an engineer for Rolls Royce aero engines here.

Alex Posted April 8, 2005 Share Posted April 8, 2005 So what turbo and boost configuration would give that amount of increase? They compared the two on T04R.com have a search on it for the setup they used and the actual figures they got. 3" is enough to be unrestrictive upto about 600hp I believe...so we are talking about mega power before running a 3" is a real problem.

Bobbeh Posted April 8, 2005 Share Posted April 8, 2005 Mine cracked at a weld too, but I think that happened because of 2 possibilies, the rear mounting point was loose and it may have caused it to ground at the Nurburgring going around the Karrousell a bit quick, as its been said, it was fixed with Titanium by a friend for £10 with a Tig, with a bigger stronger weld. I had no problems before this and have none now. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 Guys the BL is Circa £600-650 for the 4" system,. It is VERY light ( didnt bother to weigh it), and fits with better ground clearance than my NUR spec did. It is loud, but a deep loud if that makes sense. Overall very pleased:thumbs: Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted April 8, 2005 Share Posted April 8, 2005 Weight it for us Terry, your potential customers want these details, and improved sitting over a Nur spec.. even the stock exhaust it better in that respect due to the nurs horrible pipe work. Not a bad price for a 4 inch system though. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 Next time I take it off I will weigh it. Quote Link to comment Share on other sites More sharing options...
MONKEYmark Posted April 8, 2005 Share Posted April 8, 2005 I could Mark, but if i wanted fairy tales I would read Hans Christian Anderson books 30 - 60 seems optimistic - 150 seems ludicrous CJ makes no odds to me either way. i ended up going for 4" BL DP/MP as i would also go with a 4" exhaust too. not looked for the thread on supraforums. the info is on www.WOTM.com heres the text off his site (all hearsay to me) Just released and exclusive at Wide Open Throttle is our brand new full 4inch downpipe and midpipe! This custom piece is handcrafted from either stainless steel or mild steel and is a complete downpipe/midpipe which will go back to any exhaust of your choice. It is built based on the HKS manifold so this dp/mp combo will fit ANY HKS Single turbo kit, Power House Racing Turbo kit, SP Turbo Kits, and WOTM.com Turbo Kits. We are the only ones to offer a 4in dp/mp like this and it even fits better than some 3 and 3.5in ones! You can see by the picture how large it is. That is a 4in Chrome intake right infront of it. We have done extensive dyno, street, and strip testing with 3in, 3.5in, and now 4in downpipe/midpipes. Anyone making above 775rwhp with a turbo to support more will yield huge gains in power, spool, and torque. With a WOTM.com Stage III turbo at 32psi and a 3in DP/MP, the car maxed at 745rwhp. With no other changes but a 4in DP/MP the power at 32psi jumped to 881rwhp! Spool was also greatly affected and the entire graph moved over 500rpm to the left. 3in piping does not flow enough to support the high horsepower turbos. If you have 3in piping and wonder why not switch to 3.5in, the answer is why not switch to 4in? The fit and finish and second to none and the performance is unparallel. We have your solution now available at www.WOTM.com! Here is a quote from Jason Siebels, the head tuner for AEM and cars all over the United States! "Changing from a 3" downpipe/midpipe to a 4" downpipe/midpipe, even at 550-600rwhp provided me with 300 to 400rpm of earlier spool up! I haven't been back to the dyno to measure the horsepower gains on the top end, but picking up full boost that much sooner is worth a ton of power and torque even if it were only in the midrange! I am sure there is top end power there even under 700RWHP! I think anyone with a single turbo can benifit from a larger exhaust, how much is directly proportional to how much power you are making. The more power, the more you are losing on a 3"." Jason Siebels AEM Here is a post from Mike, an SP Customer. He has an SP88: "That was my car with the SP88. Dont under estimate the importance of airflow at high HP levels. My car gained 40rwhp on the dyno by taking off the "HIGH FLOW" air filter!!!! This is at the 850+hp level. As far as exhaust, the SP88 had a 4inch DP that was bolted to the Greddy PE exhaust. Taking off the muffler gained 170rwhp on the dyno!!!!!!!!!!! Who knows how much power would have been taken away if I had 3 inch piping ALL the way through......maybe 250rwhp?? I completely believe that if you have a 3'DP and Greddy PE (or similar small exhaust) and are making 750rwhp and you switch to HKS 4" + 4"DP------------->you'll get 150rwhp+++++!!" Just more proof to add to this amazing piece. Every tuner knows the importance of Air Flow and without a proper size free flowing exhaust, you are being ROBBED of horsepower!

Bobbeh Posted April 8, 2005 Share Posted April 8, 2005 I thought all US horse power figures were laughed at on this forum? So why reference such elaborate claims Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 Doesnt matter if they claim 1000 bhp and it's really 600 bhp, 3-400 rpm is still the same Bobbeh Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted April 8, 2005 Share Posted April 8, 2005 True.. but on a turbo the size, for example CJ's it probably wont make any noticable difference. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 well I have an even smaller turbo and I believe it helps the spool. Probably not by 300 rpm, but the car makes boost insanely early. Quote Link to comment Share on other sites More sharing options...
CJ Posted April 8, 2005 Share Posted April 8, 2005 Doesnt matter if they claim 1000 bhp and it's really 600 bhp, 3-400 rpm is still the same Bobbeh Yep...that was impressive Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted April 8, 2005 Share Posted April 8, 2005 well I have an even smaller turbo and I believe it helps the spool. Probably not by 300 rpm, but the car makes boost insanely early. I have no problems with that. Do you sell the same system as Ryan woons? Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 No Bobbeh, and for what it costs I am not telling people to buy it either, but I do think it helps. I have the BL 4" DP/MP & exhaust Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 BTW, the 4" DP is a VERY tight fit. There is zero room for errors. Mine sits within 4mm of the wastegate! Quote Link to comment Share on other sites More sharing options...
CJ Posted April 8, 2005 Share Posted April 8, 2005 Terry...can you remember what size DP and MP I have? Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 Yes mate the BL kits come with a 3" DP/MP as standard. Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted April 8, 2005 Share Posted April 8, 2005 I wonder if Veilsides 1200rwhp drag Supra uses their Ti system. (the one that runs 9.8 secs 1/4s times on street tyres) Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 That is a great time Bobbeh, what was the 60ft time? also what tyres. So it must have run what, 165mph+ trap speeds?? Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted April 8, 2005 Share Posted April 8, 2005 No idea. Got a video if you want it.. appears like it has a 6 speed sequential box and is pretty stripped down weight wise. - 1250bhp according to that and traps in the 150's Check out the video: http://www.exvitermini.com/movies/vsdragjz.mpg Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 Thanks. Those traps seem low for a 1250 bhp car. Great time for a 6spd on road tyres Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted April 8, 2005 Share Posted April 8, 2005 Well its probably having a little problem getting all that power down! Uses the HKS GT3040's that Leons 'sorta' running with. But yeah, very impressive never the less. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 8, 2005 Share Posted April 8, 2005 It is madly quick, very impressive, doesnt seem to have a traction problem though. Would love to know what that sequential box is, as the hollinger isnt rated anywhere near that power. Great video, well done mate. Quote Link to comment Share on other sites More sharing options...
dude Posted April 8, 2005 Share Posted April 8, 2005 Guys you dont want a 4" exhaust !!! they dont work at all Dude 4 Inches of brute force !!!! Quote Link to comment Share on other sites More sharing options...
