AKSSS Posted June 21, 2012 Report Share Posted June 21, 2012 (edited) you see 10psi at 3600rpm?? It spools pretty quick. I can show you a hpt log from a couple of runs at the track. When I went from the 3" down pipe to the 3.5" downpipe and a single 4" exhaust it made a huge improvement. I am running a 4" mbrp diesel muffler and I don't think it creates much back pressure. It's quite a difference in the downpipes. Lol See if I can link to an old video. http://s557.photobucket.com/albums/ss17/aklowriderz71/Alaska Raceway Park/?action=view¤t=KoolKruz2011057-1.mp4 This is just a single run with my boost around 12-13 psi. I was losing fuel pressure with my old fuel system. But you can really hear when the boost kicks In around 3600-4000k. I was launching around 2800 and 2-3psi. By the way. This is what I call full street trim. Everything on including my ball hitch, 22's and my bag in the back seat from driving 300 miles to run at the track. Even got about 17 mpg on the way.
