Please DO NOT Post In The General Section
From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.
The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.
For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.
Everyone will get a couple of warnings from here on out, after that I just start deleting threads.
Again if you have any questions, PM me or one of the other mods.

I wanna see some Mustang GT's being spanked!
By the way.......Have you considered using Crome as your tuning platform?
It works off the ECU, but has all the goodies you'd expect at half the price of uberdata or Hondata. I use it on my Turbo Civc and it works wonders.
Let me know if you want to do some research on it, I'll give you a link for the website.
Awesome work, by the way! Giving us CB7 guys hope around the world.14 Ford Focus ST - stock(ish) - E30 Tune + Green Filter =

correct me if im wrong but uberdata is free... well at least i downloaded a version off the internet. Maybe i downloaded an old version so it was free. I dont know... lol cant be half the price if uberdata is free...Last edited by MRKIKKOMAN; 12-15-2005, 04:06 PM.DIY antenna control

I was messing around with some turbo calculation and this is what I came up with(based on stock f22a sohc):
([2156/16.387] × 6200) ÷3456 = 236.03004cfm (air flow at 100% VE)
236.03004cfm × 0.85 = 200.62553cfm (air flow at 85% VE)
[10 + 14.7] ÷ 14.7 = (1.68:1 pressure ratio)
__________________________________________________ _______
T2 = T1 (P2 ÷ P1)0.283
°R = °F + 460
T1 = 75 + 460 = 535°R (assume outside temp was 75º)
P2 = 14.7 + X (X is pounds of boost planned)
P2 = 14.7 + 10 = 24.7 psi (with setup at 10psi)
T1 = 75
P1 = 14.7
P2 = 24.7
T2 = 535 (24.7 ÷ 14.7)0.283 = 620 °R
You then need to subtract 460 to get °F, so simply do this:
620 - 460 = 160 °F Ideal Outlet Temperature
This is a temperature rise of 85 °F
__________________________________________________ _______
Ideal Outlet Temperature Rise ÷ AE = Actual Outlet Temperature Rise
85º ÷ 0.7 = 121 °F Actual Outlet Temperature Rise (at 70% adiabatic efficiency)
Now we must add the temperature rise to the inlet temperature:
75º + 121 = 196 °F Actual Outlet Temperature
__________________________________________________ _______
(Inlet °R ÷ Outlet °R) × (Outlet Pressure ÷ Inlet Pressure) = Density Ratio
(535 ÷ 620) × (24.7 ÷ 14.7) = 1.44990 Density Ratio
Outlet CFM × Density Ratio = Actual Inlet CFM
200.62553 x 1.44990 = 290.88696cfm
290.88696 CFM × 0.069 = 20.07120 lbs/min
__________________________________________________ ________
Now you can use these formula's along with flow maps to select a compressor to match your engine. You should play with a few adiabatic efficiency numbers and pressure ratios to get good results. For twin turbo's, remember that each turbo will only flow 1/2 the total airflow.

Conversions used where there was control over conversion factors:
1 HP approx equals 1.45 CFM
1 CFM approx equals 0.0745 lb of air/min
0.108 Lb/min approx equals 1 hp
1 Meter cubed/sec = 35.314 CFS = 2118.867 CFM
1 KG/sec = 132 lbs/min approx equals 1771.812 CFM
power coversions:
1 PS = 0.9859 HP = 75 Kgf m/sec
1.3405 HP = 1 KW
1 HP = 746 wattsAttached Files

Two things....first, I just got my turbo. I know ya'll want pics, but just hang one for a second, ok?
Secondly, I'm adding the link of the base map(thnaks MRX, even though he probbly doesn't know I'm gonna use it... ), but here it is....
