Just wondering if anyone knows how much more power or performance I can get out of using a performance cam kit from CompCams. It would go into my lil 2.5 Iron Beast. Would it be a good deal of performance or would it not even be worth gettin at all? Would I be able to tell the difference?
I am looking for all kinds of info on this, so any of it that you guys can help me with, would be appreciated.
Also, anyone know a good way to boost my "off the line power"? I am not too interested in high MPH. Just quick off the line accelleration. Maybe a good 1/8 mile or 1/4 mile accelleration combination????
Thanks for any help.

There is always more to it than a cam,TBI,exhaust system etc. Read https://www.fiero.nl/forum/Forum1/HTML/003460.html it is 190hp from a duke in general fiero chat. Yes a mild cam will help. If you have the mony you can get one ground to your needs.

what dif a cam by itself will make I can't tell you. I'd say at the least you need a cam set, a header, and likely a TBI unit. (This assumes an 86 or older 4 cyl.)

It also depends what cam is in there now. The roller cam GM used is already a little more agressive than the flat one. I don't know how much more agressive you can get w/o screwing up the ECM programming. I'd got to who makes the cam and make sure they agree it runs with a stock ECM. (No one makes chips for 4 cylinders that I know of)

Give me all the camshaft specifications and I will run them on my dyno simulation program for you. I need to know lift, duration, lobe center angle or centerline, intake centerline, and if its a flat tappet camshaft or roller camshaft. If you could get the IVO, IVC, EVO, and EVC specifications that would be better. I can also tell you in terms of performance (0-60 and 1/4 mile) what you should expect if you give me your cars weight including you, tire size, overall diameter, and which transmission you have.

could you make one up for me? If so here's the info:
HYDRAULIC ROLLER CAM
050 DUR | LIFT |ADV DUR | LOBE
INT/EXH | INT/EXH |INT/EXH | SEP.
204/214 |.469/.478 |262/277 | 112

and add 160lbs to the weight of the car it's an 1984 sc, auto without ac.

Hey baldlobo, I see your specs are the same as what the Accelerated Motion kit offers, Did you get yours from there? or is it even in the duke yet?
I am looking around for a bad-ass cam, I read that the best flow for out 151 is at .440 lift. Also that unless your engine isn't set up for more RACE type situtations more lift will cause more problems that arent' worth the cause. Do you experience any of that?

88Formula: I will have a couple cam specs in here in a bit. I am in the process of lookin them up now. Does it show the stock cam specs on your dyno program to show if the newer cam is better? OR do you need those specs also?
Thanks for the help in advance 88formula,
This forum and its people are AWESOME!!!

actually I don't have the cam I just wanted to know the numbers it would produce.

Well now that I have looked around a bit, I see that there a few places that will make a camshaft to your needs.
So... 88formula, If you could let us know about the cam specs from above, that would be cool. I am still not finding any other cam specs out there for out lil dukes. JUST people that can make a cam for it.
I don't know if you have the stock cam specs. but i found them too... hehe! So if you need them to compare, here they are.
190/190 .404/.404 276/276 112

Ohh also there is another performance cam that they sell BALDLOBO, way more cam though. My iron duke wouldn't be able to hold it with my stock items though.

Hollow cow! These dynos take a little time to do of which I don't have right now. I will try to get to them tomorrow late in the evening after I get back from my side job. I can't do a Dyno simulation for everyone or I would be here all day and night. I will do the dynos for the above people and that’s all I can do for now.

Thanks,

John

I need to know the intake centerline of all these camshafts, valve sizes, and if the cam is a hydraulic roller or flat tappet camshaft. 84-86 was a flat tappet camshaft I think and 87-88 years were roller camshafts.

I filled in the blanks for the missing data and did a quick dyno for the stock camshaft. I made it a flat tappet camshaft with 1.76 intake and 1.4 exhaust valves and a 115-degree intake centerline. I got 96 HP @ 4000 RPM and 144 ft lbs. of torque @ 3000 RPM.

This will propel a stock 2770 lb. fiero (including the drivers 180 lb. Weight) through the quarter in 18 seconds at 74.2 MPH and 0-60 in 10.9 seconds. I used an 1800-RPM stall speed on the torque converter and a 3.18 final drive ratio.

I will go through all the camshafts when you guys get me the information I need. If any of the information I have here is incorrect let me know.

To find you automatics stall speed step on your brake and floor the gas pedal. Record the highest steady engine speed and that is your torque converters stall speed.

I've got one for you that you'll probably be able to do:
it's at http://www.holley.com/HiOctn/ProdLine/Products/IEC/IECC/Pontiac1.html and its the first one on that page.
ps: flat tappet and use these valve sizes intake 1.94" and Exhaust 1.60"

Man what the! Will have to get back on this one, as this will take a while.

thanx

The baseline engine with stock everything.

96 hp @ 4000 rpm 136 ft and lbs. or torque @ 3000 rpm.
That same baseline engine with just a camshaft change starting in the order that you gave.
(1) 102 hp @ 4000-4500 rpm and 148 ft. lbs. of torque @ 3000 rpm.

(2) 101 hp @ 4000 rpm and 146 ft. lbs. of torque @ 3000 rpm.

(3) 108 hp @ 4500 rpm and 144 ft lbs. of torque @ 3000-3500 rpm.

(4) 118 hp @ 5000 rpm and 136 ft. lbs. of torque @ 4000 rpm.

(5) 117 hp @ 5000-5500 rpm and 133 ft. lbs. of torque @ 4000 rpm.

thank you, I think I'm going to go with #1, thanks again.

I would too. It's the best camshaft for the street.

Let me know how it goes when you’re done.
