Detailed Specs?

[smp3000]

Sup Guys,

I recently got the desktop Dyno 2000 software and have been messing around with it. For what it's worth it seems to be pretty accurate from what I've tested it upon.

I have a few questions on some detailed specs for our cars. What are the:

1. Intake Value (inches)
2. Induction flow (cfm) @ (inHG)
3. Camshaft Type
4. Cam Specs (the default is "Seat-to-Seat")
5. Int Lift Value (inches)
and
6. Exh Lift Value (inches)

Thanks!

Check the Protege FAQ for some of that...I think the values of the stock cams are on there for lift and duration.

1: the MAF inner diameter is 57mm or 2.25" 9 sure of the throttle body)
2:depending on what numbers you use, this can vary quite a bit. I did calculations at 75% effiency and got these
(RPM) (CFM)
5000 131
5500 144
6000 157
6500 170
7000 184
if you want to try your own %'s here is the formula
CFM=(bore^2) / 4 x pi x stroke / 1728 x RPM x 2 x Volumetric Efficiency%
or
CFM=(cubic inches x RPM x Volumetrtic Effiency%) / 3464
the P5 motors have these numbers
Bore=83mm(3.26")
Stroke=92mm(3.62")
cu"=121
comp. ratio 9.1:1
3,4,5 dunno. havn't gotten there yet

The stock throttle body is 55mm...

Hence why a 60mm on N/A won't do crap, and 65mm won't do much of anything neither...

On F/I, those might do something, but not on N/A...
