Project Cheap Dirty SOHC Part 2 - 04-6-2012 exhaust and bushings
Uploaded by ghettoracer on Apr 6, 2012
Sorry it took nearly 3 months for this update lol. Time passes fast. I was very busy in February and March because I was busy becoming a partner at N1 Concepts. That's all square away now and we are in the re-organization phase still but things get moving forward and I finally found some time to get back on Dirty SOHC.
My old pal Freeman Lui from VelocityShop actually sent the HardRace goodies back in February and I must apologize lagging on this... I'm as eager as anyone to get these goodies installed so I can enjoy Dirty SOHC to the fullest. I'll do my best to have all the bushings done before April is over so hopefully you will see part 3 soon!!

mid night dyno research. added Z.SPEED 60 mm catback and ebay 4-2-1 header. even with stock cat power increase is HUGE!!

ebay 4-2-1 ceramic coated header. but the coating is so cheap it is flaking after like 1 hour driving. lame. at least it does look stainless under neath and it works well.

i was a bit shocked at the increase across the entire power band...

yes, 100% bone stock long block at the moment. just the mods listed. stock virgin p28 ecu. i'm going to rip out the AC and PS soon. i just can't resist Colin Chapman's method of "add lightness". :-) the AC was working fine when I first got the car but last week it doesn't do anything anymore. i'm guessing there's a leak in the AC system. so off it comes. as you can see Dirty SOHC's base line dyno was at 106 whp which using 15% drive train loss = 124.7 bhp. pretty much spot on as 1993 D16Z6's original rating of 125 bhp.

yesterday, i installed an old intake manifold that i have sitting around for years. it's the one that develop by omniman and dnr when they used to work at junk2 back in 2002 or so. it's a crude design but it works. basically they took a 170 bhp b16a IM and mated to a D16Z6 IM flange. then used silicone hoses to play with the length until it made the most power. there were no 3d design involved at all, simple trial and error. this is why the packaging is so poor. imo the runner is about 1" too long when i study the old project remix dyno graphs so after this baseline dyno i will probably cut this one and make it 1" shorter. :-P
still using the stock d16z6 58-56 mm tb for testing purposes. pulls much harder to redline. was going to sears point to drag it but traffic already started so that'll have to wait until next wed. will try to dyno this week.
