Returning Fiero Owner - Let's Talk 2.8 Breathing (Page 10/14) SpaceLion APR 14, 03:18 AM Ya know, as far as supercharging goes, I've seen these super small, super cheap, superchargers online. (no pun intended) And I wonder if they would make enough boost to keep up with the air demand. You can find them on youtube as the AMR500 or Aisin 500. A lot of applications on smaller engines. Someone tried on a dell sol and said that it was actually impeding airflow at high rpm, but it may just be that he hadn't tuned it or installed it right. Anyways, I know what many of you would say. Not sure if you trust it. But that's what's appealing to me, the cheap price If it doesn't work out and I'm out 250 bucks, oh well. And I have a little supercharger to play around with on something else. I just wonder if anyone has heard of them, or heck if anyone has heard of another more hashed out supercharger system for the 2.8. Not looking to inspire a turbo vs supercharger debate here, everyone has their preferences. I've had supercharged applications, I've have turbo applications, I enjoy the smooth predictable power delivery of a supercharger, and that beautiful whine sourmash APR 14, 07:59 AM quote Originally posted by La fiera: JJ, the cure for your problem is simple. Give the runners plenty of volume and speed and the plenum should have at least 3.5 liters of volume (it has to be big). The bigger the plenum, the more torque you'll make and since HP is a mathematical calculation based on torque, you'll make the HP. That 262 cam you have is basically a stock cam. The aftermaket cams available for these engines are way too soft, even the roller versions from WOT. That is what made me charge ahead in research of the ultimate intake, cam and head combo, it didn't exist so I had to make it. The norm is that if you can't make power NA put a supercharger or a turbo. Not me, I don't give up that easy. What did you end up doing for a cam? Custom grind? Did you port heads?

Cam is solid lifter custom, heads are CNC machined with bigger valve sizes. jjd2296 APR 14, 09:02 AM my cam is 260H not a stock cam for the 3.4. but ill be putting 1.6 roller rockers which will make the set up equivalent to a 272 cam. my heads are ported, polished and larger valve seats with ss valves La fiera APR 14, 11:44 AM quote Originally posted by jjd2296: my cam is 260H not a stock cam for the 3.4. but ill be putting 1.6 roller rockers which will make the set up equivalent to a 272 cam. my heads are ported, polished and larger valve seats with ss valves The larger valve will be a big help. The 1.6 rockers will get you a bit more lift than the 272H cam but very little duration. The 272 has 216 degrees @ .050 and the 260H has only 204 @ .050. with the 1.6 you'll maybe have 207 degrees. The stock cam has about 196 @.050 so that is only 8 degrees extra. You'll need at least 230 @.050 to complement the heads. sourmash APR 14, 11:57 AM What cam will do that? Custom? jjd2296 APR 14, 12:12 PM this is a wealth of knowledge. cant change the cam now but ill do the rest and add the boost next year. jjd2296 APR 14, 12:14 PM quote Originally posted by sourmash: What cam will do that? Custom? must be. never heard of one that does that that can be bought off shelf for this applicaiton La fiera APR 14, 12:39 PM quote Originally posted by sourmash: What cam will do that? Custom? Yes Sourmash. I have done all the cams for my engines and for others that want a unique not generic cam. I make them to the specific application. I don't do this for a living, its my passion. So, if in the future any of you need help on a unique cam for your application don't hesitate to PM me, I'll be my pleasure to help you. Rei. sourmash APR 14, 01:17 PM That's great to know and something I can draw myself into on some things. But rethinking for my first 3.4 I''m going to back up and not go with CNC porting. I'll intake mod, TB swap, header & cam. But curious about cams I was just perusing Crower's site and found their mechanical tappet cam with 212/216 duration for $67. lol, yes 67 dollars. The 236/242 duration cam is $222. https://www.crower.com/camshafts.html?cat=1183 I've gotta learn to weld aluminum and stainless.
