bet that goes well any pics of the car mate ?

 

nicest scooby do i know, cant wait for the passanger ride gustavo

 

Bet that's not shy

 

Is it as 'laggy' as it appears on the graph? Makes good power but doesn't appear to be doing much till 5.5k

 

well some things have to be sacrificed its 611@1.8bar v power the power doesnt tail off if u look it still makes power to 8500 rpm limiter i still have the same rpm power band just higher

 

It's making 200 bhp at 4.5k and power climbs to limiter so hardly an un-useable motor. Impressive stuff

 

That's a fair point, what have you built the car for, track use?
Presumably got a good sized turbo lol, what's the full spec?

rest of the car is standard interior etc

 

Get a few pics of the car up Gus, it's a minter.

If I wanted an engine built for a Scoob, I'd be getting an enginetuner lump in there without a doubt... great choice mate.


Cheers,
Grant

 

I didn't say it was un-useable did i, just asked if it was as laggy as it 'appears'.
As an example of what i was comparing it to i.e an evo running similar power (obviously different spec etc) , making nearer 450bhp at 4.5k.
Not to take anything away from the subaru as it must make for a bloody exciting drive

 

u could say that

 

 

Lol....that looks 'adequate' !!
Impressive spec, proper build by the look of it!

 

excellent power Gus.

glad to hear its done so well.

 

if u look 1000rpm later than his ie 5.5k i have 500
but like i said earlier mine makes power 1k later to the limiter without dropping its built fot track n drag

 

 

Was that not the turbo and supercharged evo? If it was then it's no surprise it's making more power at those revs, and if it's not and is just turbo'd it's even more impressive!

Both nicely shaped graphs and excellent power either way.

 

itll be just turbo cos the evo is 100mm stroke and scoob is 79mm the evo is a more tourqey car with the aid of spooling the turbo sooner cos of the stroke! but the evos dont feel fast like the scoob there more linear power

 

Not as far as i'm aware no, plenty of other graphs around showing the same sort of figures on stroker kit gt35 engines.
Anyway, don't wanna clutter up a thread about a different engine lol, was merely making an observation and like you say excellent power either way

 

Jesus! Bet it flies.

 

mo probs mate its a discussion forum after all

 

 

sorry for the off-topic...

does the standard scooby intake manifold not become a restriction at any time? as all the high powered scooby's i see (600bhp+) all seem to be running it still....

or is it an aftermarket one that looks similar?

he obviously knows what he is doing

 

Very Nice!!

 

the supercharged and turbo'd one from norris made 1000 bhp

 

Good stuff mate

Solid numbers there too!

 

Good figures ! I bet that flies

 

Scooby engine looks like it makes some good power. Not sure its fair to post up a graph from an engine dyno to compare it against. They always seem to look better with spool up than a chassis dyno.

 

Mines a chassis!

 

Impressive stuff....

 

Scoob engines dont in half look less clutered when they have the reversed inlet.

Very impressive figures, I bet your well happy.

 

Yeah I can see that. I was meaning the engine dyno that was posted up to compare it against.

 

Bet that flies

Has alan moved from plymouth to dubai?
37 degrees is certainly a scorcher of a day

 

I did notice that too, it would deffo correct upwards. The temp on the day was 24deg ...

 

Yes it will definately have "corrected" upwards as a result (when in fact at 24 degrees it should have actually pulled down slightly rather than pulled up massively, as 25 degrees is the base figure), as I beleive the dyno dynamics rollers are probably using the standard SAE J1349 August 2004 revised formula:



Trouble is, even if it actually WAS 37 degrees that day (which clearly it wasnt really) that formula is only intended for use up to 35 degrees in the first place, its not considered accurate beyond that and im not aware of any other formula that can claim accuracy at those temps either.

It would have clocked under 700bhp though if the temperature probe was used as DD intended, so I guess thats a big motivation to misuse it when your so close to such an "important" figure, as no one wants to tell people their car is 690 instead of over 700

Or maybe it was just an honest operator error and they dont know how the rollers are meant to be used, just cause it happened to go in their favour so much isnt proof they were trying to be dishonest, they may just be incompetant.

 

I think one graph is a RR & the other a Dyno. Mine appears to be about 1000rpm later on my RR graph to my Dyno one so dont try to compare im sure an expert on here will explain why.

 

The rollers allow in shoot44 allows the revs to build naturally at a relatively quick rate which means the turbo is less likely to spool at lower rpm, on the superflow though the graph is drawn from multiple held load sites, so you get to say 4000rpm and then you hold the engine there for a couple of seconds to allow the turbo to spool fully, then you back off and start again at 4500rpm etc.

So basically the turbo will always look like its spooling later than it in fact is capable of when you look at the results from the rollers.

same way that a lot of turbo cars cant hit peak boost as soon in 2nd gear as they can in 5th gear.

 

I would imagine Martyn jeffrey knows how to use the dyno chip

 

So why is he claiming it was 37 degrees C on the day he dyno'd your car?


Dont misunderstand me though, im sure its an awesome car, and if its 690 or 708bhp or whatever will make fuck all real difference.

Ive seen AJ graphs with over 50 degrees for intake temps, so yours is by no means the worst either!


Martyn is someone I have no respect for though TBH having seen the fucking shockingly negligent job he did when mapping Neil Adam's westfield which he charged good money for the priveledge of trying (and failing) to learn about autronic at his expense.
Wouldnt have been so bad if at least when it came to light what he had done he offered a refund, but he didnt even do that.
Personally I think Neil should have sued him, but he just didnt want the hassle.
