Ok, never mind I just did... Check my math...

3.455/pi=1.096577558
sqrt of that is=1.047175992
1.047175992+1.047175992 = 2.094351984 Diameter...

 

Do you guys want to share your LS1 setups in general? I found there's a lot of places where the information is just plain wrong (ie. cast iron block) for the LS1 engine they have in EAP3.3
I've been going through it fixing it as i find more data, but i still get the problem where about 6krpm no matter what cam you got, it just falls on its face. If anyone needs any hosting for these engine files, i could provide it, just msg me.

Also, how and what for do you guys use the EAP for? I tried to use it for picking a cam, but since it falls off at 6k, it's kinda useless to me.

 

I agree I have found bad info. The other issue is that mine dies at 6000 also, I don't know what the issue is either... I don't mind posting what I have thus far.

 

I have the same problem with EA Plus. No matter what I do it's all done at 6k rpm.

 

Looks correct to me. Math isn't my strong area.

Do you have some flow numbers of the LSx intake with and without a LS6 head to figure the flow coefficient?

 

I use it to see trends in performance with different parts. It's been useful for me.

How do you want to host component files? It would be useful to have the file with the component title and any assumptions made in the creation of the file. I don't mind sharing what I have so far.

 

well, the easiest way to do this would be to have all the separate component parts as different files, but the whole thing should be probably zipped up into one package, for easy handling.
feel free to send them to marcinpohl@gmail.com i'll make a page out of them once i have few of them, i have loads of storage and bandwidth available.

 

I'm using EAP3.3 and the power on my engines is peaking around 6250-6500, and peak torque from 5000-5250. I am getting a big dip in the torque band between 3000-4000 which doesn't reflect on the real dyno.

 

Here are all my LSx related EAP files.

 

What are you guys using for the actual flow rates of the intakes? I've been digging and digging and cannot find flow numbers for either the LS1, LS-6, nor the LSX intakes. Any info would be more than appreciated.

 

I use the flow rate of the throttle body. The numbers I've found seem to indicate the stock LS1 TB flows ~800CFM (Accufab Throttle body CFM). Most sponsors advertise their porting increases flow about 100CFM. So, I should be using 900CFM I suppose, but I play around with it.

The book LS1/LS6 Performance by Chris P. Endres has flow numbers on the LS1 and LS6 intakes. I have been using the flow numbers from this book to figure the flow coefficients for these intakes. I haven't seen any good flow numbers for the FAST LSx intakes.

 

I didn't purchase that book because of a little 'factual' info. in there being questionable to a few well respected pals. Though I'm after accuracy on this subject, being slightly off wouldn't be a complete disaster as it will be used for info. purposes only. On that note, could you buy any chance post the numbers? Again, more than appreciated.

 

What data are you referring to that is questionable? I'll post the data on the intake's.

 

Just looked at the book. It lists stock intake port flow numbers bare and then each manifold attached to each head and then flowed again. It doesn't list intake only flow figures. Sorry.

These are the exact flow numbers that I need to calculate the flow coefficient for each intake in the program.

 

I cannot recall exactly as it's been a while. It may not have been much, but enough where I was recommended not to cough up the dough for it...

 

What are the numbers? That may help me as well.

 

Here you go, in Excel format. I updated and put the data that I have for the FAST LSx intake also.

 

Believe it or not, that's exaclty what I was after...Thanks!
