Ok cool Mike. My mistake. Sorry.

Where have you got it from that Chip assumes Mark doesnt know what he is doing? Time for you to take Chip off ignore i think and actually have a discussion.

Chip

God you really are a total moron Mike.

I said nothing of the sort, so dont put words into my mouth just to try and hide the fact that yet again you are spouting utter nonsense when you havent got a clue what you are on about.

Stop pretending you have the first clue about things like compressor maps when you clearly DONT, as it just confuses other people who are trying to learn.

All that map tells you, is a vague range of possible values at that boost level, nothing specific at all about what power it will make, if you knew what a compressor map represented you would realise this like the rest of us do!

Chip

I think he prefers to just put his fingers in his ears and pretend no one is actually noticing that he is totally misleading people by pretending to know what he is on about when he doesnt!

Mike, didn't realise you had Chip on "ignore".

I actually cut the non factual bit off the bottom before quoting it. Full version above.

LOL @ Doug.

Ive got nothing at all against Mike, and just everything against utter nonsense, ANYONE who had said the same utter rubbish that Mike did, would have got the same response from me, nothing personal about it at all, I would just prefer PF to be full of accurate information not the slander and technical nonsense that Mike occasionally wanders off and engages in like he has done in this thread (it always seems to be the moment MAD is mentioned that he spits his dummy out on here, but maybe thats just co-incidence).

Mike doesnt like being corrected and he doesnt like people pointing out when he is being a total hypocrit like happened recently when I pointed out what utter shit he was talking about dynos, so he has thrown his toys out of the pram and declared that we are no longer friends and all that childish nonsense
Personally I cant see the point in falling out over someone correcting someone else on the internet, it gets corrected, everyone realises he was talking nonsense or being a hypocrit again, and that to me then is the end of it, and it shouldnt effect offline friendships.
Im not going to judge him as a person just cause he posts nonsense on here, and I dont see why he would want to judge me just for correcting him when he does it.

peak/hold 28 psi and on a dd roler what bhp at 6250 at 28 psi ?

425bhp maximum on standard head ports,thats what i heard very interested to see.

Because from the compressor map he is saying there is a possibility Mark will only see 350bhp @ 2.2 bar, whereas I have looked at the compressor map and thought that Mark will get the most that the turbo can achieve at that boost (with a small reduction for head port size) .

Hence I have given a figure of 440bhp based on a best guesstimate on the c/r you have posted, the assumed ignition values for that c/r (late teens on the top line), the compressor map for the turbo and the boost you are going to run.

Jay,
I would "guess" at 360-370bhp .

Im saying the compressor map says there is a possibility mark will see only 350bhp, it also says there is a possibility he will see 480bhp or so, it also says potentially he will see surge at certain RPM points depending on the VE of the engine.

I know from personal experience he wont see 350bhp, but there is NOTHING on the compressor map that tells me that to be a fact.

Oh look, Chips at it again....

and on and on and on x1000

I reckon 400+bhp and 400+ torque

If you believe there to be an error in something I have posted, then point it out so your post has some merit.

If you simply dont like lots of accurate posts by me, then click on ignore.

Either way there is no point at all in you commenting on it.

Jay,

iTrader: (4)

you see read a compressor map will idicate what a turbo can do in a correct enviroment but its not always the case

so the answer mike 280 bhp with 8 degrees of ignition so the next run i added 5 degrees from 5000rpm to 7000 then see 330 bhp , after several runs and det checking eventually ended up with 19 degrees of ignition and 383 bhp ande a stable egt so looking at a compressor map isnt god and to think you can add restrictions like shit airflow through the cooler and head then charge temps deducting ignition if to high so imo a compressor map means theres a rough ball park imo as the end results is only obtained if IF the total spec either works by luck or is correct then the person who can map a car that is spot on .

So ideally it will do what it says on the can but rarely does lol due incerficant spec or mapping

i havent seen a comp map for my turbo. What is the most bhp it can run and at what boost?

Mike Rainbird

iTrader: (3)

Read what I posted you nuggart .

I already KNEW his c/r (he posted it), I already KNEW what turbo (he posted it), I already guessed at the ignition values they would be trying to run (late teens as per my post above ), so I just needed the boost pressure to give a guestimate of power (it was the only thing I wasn't 100% sure of ). So in effect, asking for the boost pressure being used was the final piece of the puzzle to enable a calculated guess rather than plucking a figure out of thin air .

I've seen enough of these engines to know what ignition value you're going to TRY and end up with .

Why didn't you leave it at 8 degrees if you wanted to prove a point . I think I could work out that Mark isn't as "retarded" as you .

sorry

Mike Rainbird

Chip has already posted the airflow , so at 46lb, it has the potential to do over 460bhp with the engine VE at optimum .

CossieRich

iTrader: (1)

actually quite the opposite. Some interesting points being raised on here and technical to. I see under your username you have slow learner. Seems to be correct as this is nothing like handbags what-so-ever

Chip

iTrader: (3)

Actually Jay, what you are saying there is a nonsense.

Mike has already said (or implied) that it is a given that in Mark's case the mapping will be spot on, so I think its fair for him to assume that it wont be 100bhp down due to the wrong ignition values.

A compressor map puts you in a useful ballpark based on some other guesses, it doesnt allow Mike to do what he said which is:
As it shows airflow at that boost level over a big range, as ive already mentioned, so you cant see what it is doing, you can only see a range of what it can potentially do.
I dont believe he needs a compressor map to know that a GT3071 is vaguely in that sort of ballpark. But maybe ive been unfair and he knows so little about these turbos that he actually DOES need a compressor map just to see what ballpark its in so he can make a complete wild guess, but if thats the case, his reply was worded badly.

I would say 380bhp and 390lbs as the rollers will be reding under powdered that day

Jay,

iTrader: (4)

sidestep mike so obviously u no the airflow is fine to cope plus other things to be tacken into acount u numpty you cant get bhp figure that easy

Chip

iTrader: (3)

So what did the compressor map tell you that you DIDNT already know, as apparently you said you needed the map?

Did it tell you that a GT3071 is a comfortable as a vaguely 400-450 bhp ballpark turbo?

If so, im amazed you didnt know that already TBH!

CossieRich

iTrader: (1)

you wish Steve. Thats the only way you would be able to beat me when your escos gets back

Mike Rainbird

iTrader: (3)

I would concede that if it was an engine I knew nothing about VE wise, then looking at the compressor map would not enable me to do anything other than give the range of power that Chip quoted.

However, I have seen enough of these engines to know how they perform at certain airflows and the fact that Rich has listed all his ancilliaries in his resto section (quite a lot of which I actually provided ), I think I can give it a pretty accurate "guess" - we'll see tomorrow won't we ?

Does that make you happy?

Jay,

iTrader: (4)

Chip

iTrader: (3)

Of course.

So if you know that the compressor map was only going to give a range that the figure already was blatantly already going to lie within (as per what you just said here), then WHAT did you need the compressor map for?

Thats my WHOLE point, that you are making out you could get useful information from the compressor map for Rich's engine, but the only way that would be true is if you had NO idea at all what sort of airflow a GT3070 is capable of, and surely you must have at least had a vague indication?

Mike,

you havent provided me with any ancilleries for my engine as it was built 5 years ago before i knew this gay blond haird bloke caled Mike Rainbird existed

Just to make this easy my engine spec:

7.6:1 c/r
BD14 inlet
Standard head ports and standard exhaust cam
GT3071.82
4 x 750cc injectors
