Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

69trk,

I need to know what the lobe seperation is on your cam or exhaust centerline. You only gave me intake centerline. I could not find any cam timing info on the web. I have the rest of you motor done and ready for it.

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

Phipp13,

I need to know what pulleys you are running. Crank and blower size or number of teeth on the coggs. It won't let me simply put psi in for boost. I have everything else done and saved.

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

Sinister,

You gave me flow numbers, but at what lift?
No compression ratio
I'm assuming 112lc is 112 lobe seperation. What's the intake centerline?
I'm assuming the intake is a single plain?

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

68 C-10,

I tried finding the lobe seperation or exhaust center for that cam and was not very lucky. If you can find that, that would be great. The rest of it is saved.

69trk

Can you please give me the details on your truck.. I want to see how it does with your ET/MPH based on your combo.

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

I'll try to play with the truck stuff later tonight or tomorrow. I am leaving for dinner in a few with my wife..

As far as headers. I quickly plaid with diameter and length as well as doing an optimze.. Believe it or not, you are not loosing much with you current set up. With 2.25" x 41" your only gaining 5ftlbs at peak and 2hp at peak.

I have it optimizing your cam while I'm gone. Normally an hour long thing.

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

It sounds like there is no need to dump $700 in a new set of supercomps.

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

shaun,the crank pulley is 6" and the blower pulley is 2.625". i believe thats 144% overdriven. i really apprechiate you doing this for me. what do you think of my cam profile?? i was told that it was a good cam for running a blower by the people who sold it to me.also i just looked at the dif between 1.5/1.6 rocker ratios and corrected lift 4.88/5.10@1.5 should be 5.10/5.44 for a 1.6 rocker
here is some added vehicle info
weight 3800 lbs
racing turbo 400
stall 3200 kinda low for blower app
ford 9" posi diff 4.10
tire 31x16.5x15
weight bias 55/45

v/r Phipp

Here is your engine dyno stuff.. Unfortunately, I'm getting the "converter is too low" to make it work in drag analyzer. I'll play with it more.

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

Hey 69trk,

Does this look a little more like your graph?

I had the bearing and piston tolerances set to production vs race. Seemed to make a little difference

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

The program is funny with the converter.. Not too sure why it does it. But in all reality, you could use a bigger converter

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

I wish I had decent cam info on my old combo but I bought a cam that was way to big(supposed to have been a custom grind for my combo) and it wouldn't run so I borrowed a cam from one of my buddies. I have the box it was in at home but it was a regrind so I don't know how detailed the info is.
