Want to know how much power your engine is making?

Alright Gents

I just ordered the Engine Analyzer Pro v3.5 after using their trial software for about a month. The software should be here in a few days and I am Jonesin' to input some engine setups.

I have the software down pretty good and some of you may have seen some results posted as images or files in some recent threads. I have the trial until the 19th and the software should be here by the 18th.

If you want me to input your engine setup to see what kind of power it will make please let me know, and the more specific you can get the better, I can select from just about any of the popular stock castings as well as the full catalog of Brodix, AFR, Edelbrock, Indy, and a few other Manufacturers of heads, as well as all the stock High Perf camshafts, crane, comp, and alot of mopar and bowtie parts. I can also input specs on any short block, heads, intake, carb, exhaust system, with a full range of climate and altitude settings, as well as fuel octane.

There are also screens to watch the engine in action, to check for piston to valve clearance and calculating cylinder pressures. These results will be more accurate the more specific you are. And we should be able to get within 5-10% of actual. And if we can't I want my 450 bucks back.

Let me know what you have and I will tell you what it will do.

Thats a generous offer, kind of like asking IRS for an audit, brace yourself for the hit.

I for one would enjoy inputting my motor, I'll send you some data when I get home from work this evening, you prefer a PM? Can you input boost numbers as well?

Thanks, Larry

Yeah there are specs for nitrous, turbos, centrifugal, and roots blowers. Here are the screens for those specs

Oh and yeah I imagine I will be running numbers for quite some time.

Here are all the possible inputs for the specs of the motor itself, if you have crane, or comp part numbers for your cams, or casting numbers for your heads then you can tell me and those screens will fill in themselves.

I couldn't make a graphic of the screen for conditions but if you want you can tell me the weather (air temp, barometer), altitude, octane, nitrous (how many stages and what they are rated at, or progressive), and if you have a specific spark curve or if you want to use the one giving best power.

Bracketracer I will get to yours next but for right now here are the results for mpate

There wasn't alot to go on, and as always pay no attention to the labels they are usually left over from an example that I start from to save time. I guess I don't have the more recent Lunati's on file but I picked an older one that was similar and entered your specs from the 60100, I think you could go with a 60103 and see big gains. Especially if you are going to run at over 5000 rpm at all.

PkTq 403@3500
pkHp 329@5000

As you can see this combination would make for a very smooth power curve and would drive nicely, from the programs analysis your combination could use a more aggressive cam. Your Idle Vacuum will be 18 hg which means that your cam could increase duration without scrificing driveability, and you would see significant power gains.


The second graph shows the additional gains from a 60103 and your idle vacuum drops to 13 which is right in the range you want.

Ok back at it again,

With headers and 2.25 exhaust.

PkTQ 441@3500
PkHp 338@4500

Actually you done pretty good, if you look at the graph you have a nice flat torque curve and it is all in your useable RPM range, that you specified

I ran it again with a comp xe256H and there were gains of 4 ft/lbs and 1 hp then again with a comp 270h which requires some lower gears but can still be used with a stock torque converter and got less torque and a few more ponies it was all pretty close though and a lot less driveable.

I think you made some good choices, you probably could save some hassle by getting a smaller carb (650), so you wouldn't have to tune it as much you would lose a couple foot pounds and hp but it might be worth it...Just a thought!!!

I mislabeled the graph but that is for your motor. SBCfan
