RGTorque Posted June 16, 2009 Author Share Posted June 16, 2009 sorry for delays. i got the rest of the clamps/silicone elbows/ flex pipe to the shop on thursday but there were others lines up so im waiting my turn. all thats left is : ~ finish fitting ic system / install clamps ~ connect exhaust outlet to exhaust (possibly redo exhaust with 2.5" pipe!!!) ~ install some heat shielding under the hood/along frame so i dont blister the paint ~ coat turbo (hot side), turbo header, downpipe. all mods to make this mess good looking will be done over the winter Link to comment Share on other sites More sharing options...
pureadrenalin Posted June 16, 2009 Share Posted June 16, 2009 (edited) I would suggest 3" exhaust from turbo back. If you've never modded a turbo car before, it's all about flow. Backpressure doesn't mean much anymore. I know it seems REALLY big, but, 3" isn't bad and the extra 0.5in will net you some gains on spool, and HP. I don't know how much room is there as I've never seen a westfield in person, but, I would think REALLY hard about doing it.

scannon Posted June 16, 2009 Share Posted June 16, 2009 I agree on the 3" exhaust. Turbos love high flow exhaust systems. Corky Bell once told me the ideal turbo exhaust is an infinitely expanding megaphone. I have a 3" system that steps up from the 2 1/2" turbo outlet to 3" in two steps. Right after that the divorced wastegate pipe merges in and it exits the engine compartment. From there it flows through a 3" metal cat and 3" glasspack muffler. To get it under the car for a rear exit it spits into two 2" stock Caterham tailpipes. You could use oval piping instead of two smaller pipes.

RGTorque Posted June 16, 2009 Author Share Posted June 16, 2009 unfortunately i have 0 room for large exhaust as im running it down the center channel. i will be happy if i can fit the 2.5". im running no cat and 2 2" resonators (after y pipe) out the back. i think for my 8-10psi setup im not going to be left wanting. btw, i dont have a westfield, i have a world class motorsports ulralite.

I can understand wanting clean lines, but, if you do a 3" out the side, with a small HKS style muffler, or even just an angled dump after a resonator it's still going to be much better than a 2.5 down the center. Even that it's only 8-10psi, there is much to be gained with a larger exhaust. My DD is an SRT-4, and with just a 3" DP, I gained about 12hp, and dropped my spool time by 400 revs....I hit full boost of 17psi at 2600rpm. I don't know what turbo you have, but if it's a TD-04(15G) 3" is a must! Link to comment Share on other sites More sharing options...
RGTorque Posted June 16, 2009 Author Share Posted June 16, 2009 exhaust is not going to go out the side, period. i am well aware that this is not optimal. regarding the turbo, its a gt28r. Link to comment Share on other sites More sharing options...
Mondo Posted June 16, 2009 Share Posted June 16, 2009 (edited) If my wife knew their was an ultralite out there without the side exhaust she'd make me do it regardless of performance! Of course yours is a different motor and all.... I am working on a heat shield though. Edited June 17, 2009 by Mondo Link to comment Share on other sites More sharing options...
RGTorque Posted June 17, 2009 Author Share Posted June 17, 2009 update with more crappy pics, yayayyayayayya! http://img36.imageshack.us/img36/1560/cimg2754resize.jpg http://img191.imageshack.us/img191/1585/cimg2749resize.jpg http://img10.imageshack.us/img10/556/cimg2751resize.jpg things to see: ~ intercooler is now all plumed - im not overly exited about some of the wide bends or reductions to small pipe. will be fixed when i make this all pretty over the winter. ~ turbo downpipe is almost done, and need to install some bungs for my O2's. ~ exhaust is going to be in 4 sections for ease of removal. 1)turbo header to the pipe that runs beside the trans and frame 2) straight pipe that runs along trans to frame between the seats 3) from frame between seats to y splitter 4) from the splitter going to the two mufflers (incoming 18" hushpower II mufflers next week) on a side note the shop secured my fuel tank so it no longer slides side to side when i pull some g's. cant wait to try it out. o btw, car will be done tomorrow baring any issues Link to comment Share on other sites More sharing options...

Hey, it's all good..your car not mine. The 28R is a good snail, you should make some really good numbers with that. And your right..I see how tight that is, ridiculous.

RGTorque Posted June 19, 2009 Author Share Posted June 19, 2009 (edited) so the turbo system is done, well the fabricator is done... i brought her home on wed and right away i had issues im blowing smoke. im praying right now its not the turbo but im losing hope every mile. i have already upgraded the pcv valve as well as put a breather on the other crank case vent, and put a oil restictor on the inbound feed side with no luck. im hoping that the oil im seeing is leftovers from what leaked into the sistem but its looking grim at this point. thats what i get for trying to get away with a used turbo.... anyway, here come the pics new autometer sport comp 2 gauges, center channel exhaust routing and final turbo pix. things i dont like but will be fixed over time: welded up coolant line coming around the motor lack of cooling to radiator http://img10.imageshack.us/img10/5953/cimg2771resize.jpg http://img132.imageshack.us/img132/8125/cimg2762resize.jpg http://img193.imageshack.us/img193/1769/cimg2767resize.jpg Edited June 19, 2009 by RGTorque Link to comment Share on other sites More sharing options...

7evin Posted June 20, 2009 Share Posted June 20, 2009 Dam Roman... You really wanted quieter exhaust...... Looks good though... I'm tired just thinking about it... Cheers K Link to comment Share on other sites More sharing options...
pureadrenalin Posted June 22, 2009 Share Posted June 22, 2009 How much shaft play is in the turbo? That will tell you right away if the oil seals are blown. At worst it's going to be the CHRA. Link to comment Share on other sites More sharing options...
RGTorque Posted June 22, 2009 Author Share Posted June 22, 2009 (edited) spoke to the blouch turbo and was told the following. turbo is at 30 degrees which is breaking the cardinal rule of turbo mounting. oil is pooling on the exhaust side causing blow by by the seal of the exhaust side. as told to me by bob at blouch: the garret ball bearing turbo is a very simple unit and most of the oil leak problems that he sees are related to improper oil routing (not my issue) and improper mounting angle. also the seals are not a neoprene or rubber type. they are metal and basically piston rings so they dont "blow" like older turbos. they generally get wear on them after the bearing fails and begins to rub them. ive already spoken to the fab shop, we are trying to get this fixed asap.

Ah, well there ya go. It's a good thing it's not blown! I know it come down to room now, how much is that 30* difference going to make in your mounting, and hood clearances?
