600 bhp out of a 24v cossie

Whod ever have thought 200bhp per litre would be so difficult

 

 

or steve 100bhp per cylinder

 

coonts lol

but your very true its has taken time and its not thats good


The power curve looks like a YB though

 

piece of cake and easy to do

 

The bhp and torque cross over at around 4900 rpm

The graph is from a badly calibrated dyno or a fabrication

Mark

 

if you read the dyno is out of calibration at 500 bhp and knowing the guy I believe it.

at 18 psi the a 24v cossie should make over 600 bhp. the main problem the block explodes and high rpm


I don't know have long it would last

 

18psi means nothing! psi is an indication of pressure not airflow, a car could have 1bhp at 18psi

and agree the power/torque crossover point is well out.

bit of a shonky dyno sheet, like the one trubador had on that RST...

 

steve I know the standard air flow of a standard 24v. I have seen with my own eye's a 24v running 7 psi make 320 bhp.

But I must admit not sure about the cross over though

 

that graph looks like i drew it on photoshop controlling the mouse with my penis

 

But you dont know what turbos hes using do you, and you dont know what head or cam spec either, never mind exhaust and intercooling.

psi is just PRESSURE on the inlet side, not flow, and power certainly dont rise anything like equally with boost pressure.

Just cause some 24v got 320bhp at 7psi dont mean that (if the engine was strong enough and it had the fuel for it) that it would be 600bhp if they turned up the boost to 18psil...

Engines dont work like that mate....

Is the 5125 (or whatever RPM its supposed to be) torque / power crossover pointonly apply to 4 cyl engines?

I.E. isnt it a different number for different engine configurations?

Neil.

 

I agree Steve

I know one 24v TT which produces 274 a 8 psi and the other as above. There are loads of factors yes

But a good 24v with right fueling should be close to that fiqure

 

No Neil. The formula is:

BHP=(TORQUExRPM)/5252 so when RPM gets to 5252, BHP has to equal TORQUE.
In that graph, the lines cross at around 4900, so something isn't right

 

.....and just for fun, here's a bullshit dyno sheet that I made earlier



I made it for a discussion on here a couple of years ago about how much (little) torque F1 engines have. It is mathmatically correct, but pure fiction, based around knowing that F1 engines at the time were making 800bhp at 18,000rpm or so, and that they idle at about 6000rpm.
