66724, Kn0obs Question of the Week
Posted by Skrilla, Jan-16-04 06:39 AM
I saw this briefly a few weeks ago so I thought I'd spark up some conversation about it, that pertained to us and our possibilities.

I posted this in the Performance section instead of the turbo sections because it has to do with engine limitaions and that more kn0obs visit this section more than the turbo section.

We have 2 engines, both running T3/T4 Turbos, we will go with a "large" A/R (any "large" arbitrary "wheel" :) ) on the 2L and the 2.4L with 25lbs on pump octane 91-93(doesn't matter) -We will rid TQ from this equation-

Which will yeild more power, Why?

Cliff Notes:

T3/T4
25lbs
Which makes more HP? the 2L or the 2.4L and why

asuming we grabed the 2.4L pt cruiser enging for this.

2.0L = 123 cid
2.4L = 147 cid
boost = 25 psi (2.7 bar)
using a value of 0.052 bhp/cid psi for the low end and 0.077 bhp/cid psi for the high end.

bhp/cid x cid x (boost + 14.7) = bhp
the 2.0L would make between 254 and 376 bhp
0.052 x 123 x (25 + 14.7) = 245bhp
0.077 x 123 x (25 + 14.7) = 376bhp

the 2.4L would make between 304 and 449 bhp
0.052 x 147 x (25 + 14.7) = 304
0.077 x 147 x (25 + 14.7) = 449


the 2.4L also has a higher air flow rate.
therefore more oxygen is avaliable for combustion equals more power,
assuming an %85 volumetric efficiency

air flow rate = (cid x rpm x 0.5 x Ev)/ 1728
0.5 is due to the fact that a 4-stroke only fills on half the revolutions.
Ev is volumetric efficiency
1728 converts cubic inches to cubic feet
note: this is non boosted ( we'll get to that)

2.0L = (123 x 6000 x 0.5 x 0.85)/ 1728 = 181.51cfm
2.4L = (147 x 5200 x 0.5 x 0.85)/ 1728 = 188.0cfm

boosted air flow is presure ratio x basic cfm
2.0L = 2.7 x 181.5 = 490.05cfm
2.4L = 2.7 x 188.0 = 507.6 cfm

so all other things being equal the 2.4L will win out

feel free to rip since im new to the whole turbo field and a Noob to boot

granted i don't know much of jack shit about them.... i was gonna say it probably depends

if you have aggressive cams, headwork, bottom end raised compression, proper fuel setup, manifold work and quad throttle bodies, i'd say the 2.0 could make just as much if not more than the 2.4 (if it had stock manifold, head, cams, and such...)

but if all of those factors were to be equivalent then i'd say the 2.4 could make more, but i couldn't explain why

yes i'm a noob lol

LMAO

seriously, good job, this is the kinda Kn0ob I like to see...

...even busted out fomulas I haven't seen in a while LOL :thumbsup

Good job foggy. Long rod motors of the same size bore tend to be limited on HP, neverthless they make more than their little brothers,, the question is how much and even that was answered(on paper...)
