performance cams 3.0L

[evanesce69]

Any of you guys know of anyone that makes performance cams for our 3.0L

This one's for wicked sludge;

Performance?? 3.0?? Hahaha Those words shouldn't be used in the same sentence

 

[almostclueless]

Oh, there are cams out there....there are a couple of threads here on that subject.

The OEM cam is pretty much optimized for low and high end. If you change the cam parameters, you have two choices 1) better low end torque, sacrificing high end HP, or 2) better high end HP, sacrificing low end torque.
The only way around this is with VVT, which the 3.0L doesn't have.

i am leaning towards the high end. our engine is from what i have read and experienced, a revver. I'm not looking for a lopey saturday night stoplight type cam, just something a little more than stock.

It's for my E85 motor, but it isn't going into the first build. The first build will be strictly compression.

I'm familiar with morana and camcraft. I was wondering if any of our members knew of any other manufacturers.

I'd be calling Compcams and having a discussion with them guys.. Be prepaired to talk about what your rpm will be at hiway speeds. If you intend to raise the compression they will need that info also. Simply throwing a new cam in there isn't going to do you any good unless you and the cam company knows in advance a few things about your engine.

Maybe you'd like to get one of these softwares to play around on http://www.motionsoftware.com/products.htm

I have dyno2000 and dyno2003. I wouldn't dare buy a cam before checking the sims first! I don't know what they cost now, but back when I bought them they were only around $100.

I also got the drag2000.... I can design an engine and stick it in a vehicle with any tranny I want and change all the gears for the best times/speed OR just let the computer figure out what the best ratios are. Its neat.

 

[evanesce69]

you wouldn't happen to have a copy of that program that you could part with ???


i am getting a set of copper head gaskets that are .022 thickness with .004 stainless o rings, 3-4cc domed pistons and 47 cc heads. compression should be anywhere from 11.43 to 11.66 by my calculations

 

[Just_Randy]

Are you familiar with torrents? Dyno2000 and 2003 is "shared" all over the net. http://www.google.com/search?hl=en&safe=off&q=dyno2003+torrent

Its only $50 for the basic dyno version which is about the same as 2003. http://www.proracingsim.com/purchasejac2.htm You'd spend about that much on sparkplugs n wires or a tank of gas and those software engineers deserve every penny they can get... Its boggles my mind how they can do that stuff.

I'd like to get Dynomation 5, but $600!!!! I'd need a sponsor.

Here's a screenshot of the compression ratio with the specs you listed. I had to guess at the head gasket bore diameter and I assumed a zero deck height (doubt that's actually what it is, but...). And it was easier to just subtract 3cc from 47cc than it was to choose the "dome, dish, or valve relief piston". I got 11.41 CR. 11.63 if its a 4cc piston. But if you have any kind of deck height at all (> .010), you'll drop back down in the 10's pretty fast.

 

[evanesce69]

there is only one thig I can say.....


SAAA WEET!!!

So I can get this off frostwire then?


well, I found the actual dome volume, I figured it to be about 1.6cc (.032 x 1.966) kinda whimpy, but anything is better than nothing


grumble grumble whimpy dome.....



if i can make the piston .01 proud then i can get it in there!!!

 

[Just_Randy]

I never heard of frostwire... but I guess if it works....

If you're going thru all the trouble to put new pistons in, you might as well have them zero decked (or maybe even above deck if you can). Actually, it would be better to run flat pistons if you can get the same compression by decking and milling. Domes spread the blast out too much... as I'm sure Dynomation would illustrate.

 

[Just_Randy]

So, with a 45.4cc head, 3.55 inch head gasket, and zero deck we got 11.11 CR.

With flat pistons its 10.79 CR.

 

[evanesce69]

i put in there that if i can get the pistons .01 above deck it would be great, but the color of the text made it so that a person can barely see it

i did something with the editor and it got screwy on me... duh...


frostwire is an another open source version of limewire created by "concerned" limewire source cotributors, published under the GNU general public license




ok so i'm gettin 11.1:1 where stock is 9.3:1. not quite where i wanted it, but it will due for the first build.


Now to assemble the parts......

 

[evanesce69]

Just Randy - This program rocks.......


Says I should get around 171hp@4500 and 223ft/lbs at 3500
