Yes, but there is nothing to forget, as I said in the T66 thread that I would NOT be posting them up as a direct result of the bickering on that thread, unless you forgot that? . Plus it's fun winding you up .

However, you're running SEVEN more psi than me, and on my engine, each psi is worth 22bhp, so if you reduced your boost or I increased mine, they would actually be pretty evenly matched until 7500....

Not me
Just want to see the figures and to see if they are as good as everyone says they are..
Mike was quick to comment when l posted my figures so want to return the favour

i forget nothing. Plus i havent even asked to see the graph

For everyone who's forgotten, Mike's not a whiz kid on the old PC's, he tried posting the graphs on the board earlier today, but the sellotape wouldn't stick to the screen
Getting back to the thread title.....

mike, sorry for the noob question, but if youre running 29/32psi, and seeing a drop between the two relating to 22bhp/psi, and 29 psi is about 44 absolute, then 44x22=968bhp.
I know thats not an accurate figure, as the further up the range you go, the more restriction you see as flow increases, so if anything its making more power then that.
Im also realistic enough to realise that you do not have a 1000bhp trackday escos.
where has my thinking gone awol, or was the 22bhp/psi related to somethig else, or just wrong?

The correct figure for a T4 engine with Nick Waple head fitted is 10 - 11 BHP per extra pound of boost.
This is what Harvey told me in reference to my T4 SCS engine. I'm reasonably sure Mike has got that figure (22 bHP per extra 1 LB boost) wrong.

Something i was going to ask as well. How linear is the 22hp/1psi - that is a HELL of a lot - and very impressive You have a T4 - i take it is a far cry of the RS500 spec - as that is well off the compressor map at 500hp. I suspect that you probably hit a brick wall power/airflow wise one you increase the boost more than you plan to use the engine at - due to the turbo?
Anyway, good luck with the new liners - and i look forward to seeing it on track

If it made 22bhp per psi at one particular point then there was something wrong with it at the boost setting just prior to that, simple as that, there is no way its making 22bhp per psi consistantly for exactly the reason alistair gave, also like alistair said typically at the top end (due to both pumping losses and intake temp increases) you will make LESS bhp per psi than lower down, not more.

In the world of Cosworth tuning, accoording to some, it's never good enough to be happy with what you have. Apparently you also have to put it through trial by internet, so some straight line merchant can compare and be proud of the fact that their engine made 30 more bhp at the same boost, even though the specs are completely different.
Of course, since Mike hasn't done 200mph, I don't know why he hasn't killed himself in shame already.

By the way PONgo it will run past the present record 'OFF' the gas & way past 210 'ON' its the only way that your ultimate Power can be proved & must really hurt the 'talkers' that abound on here. .

why everyone still argues abotu torwue I do not know, unless youre spending a lot of tme at one particular load site like in a top speed run. On a track, the only bit that matters is the area under the power curve, related to the mass and rolling inertia of the car.
Whether you choose to make 12 from 3 torques and 4 revs, or from 2 torques and 6 revs is irrellavant so long as your grearing is suited.
You can argue whether mark makes 500ftlbs from a 500bhp engine where harvey makes 400ftlbs from a 500bhp engine, or whether harvey makes 500bhp from 400ftlbs where mark makes less. Its entirely conceptual and totally fucking irrellevant.
I find all this bickering a bit childish tbh, and Im interested in seeing any graph for interesting engines reqardless of where the cheque was posted to.

Mike,
Proof or STFU
PMSL @ all those who are backing Mikes decision to hide the evidence.
They are either "Harvettes" or have been PMed the graph.
Agreed 100%

Stoo,
I should edit it to say "and including his (ex) moderator chummies"
Ultimately its his choice but I am 99% sure if anyone else was making
such power claims and comparison to a MAD engine then he would be first
with the "proof or STFU" comments.
It is this irony that makes me want to know what he is hiding from now

this threads fucking top class.
these debates are what sets pf apart from the rest.
personaly i dont think mike should put them up as its really only a bit of paper id much rather see the car perform!!
but regardless keep the bickering up
