I know where this is gonna lead but I'll post it none the less for now :rolleyes:

 

Dyno chart from a Z32 running PE1420s at 23psi - check out how it holds around peak power for a good chunk of the rev range :D This is where its at :D

 

 

CheerZ,

 

Andy

what does the area under the curve represent though?

You just luv your pe's mate dont you

 

Mike

Forgot to say, that was with some dodgy fueling higher up the revs as well :)

Anyone else notice anything real dodgy about the graph? Is it a scan or is it a drawing? :rofl: :rofl: :rofl: :x:

That looks preeetty good. :)

 

Here's a dyno run of the turbo I've just bought, or will do today.

The graph shows RWBHP and is on an SR20 but it's going on my CA18.

Message (kind of rant-mode on)

One major problem I've noticed over all of my years here on Twinturbo.net is that the average joe has no clue how to properly interpret data. If anybody shows a dyno and proclaims, "Look, our special brand X makes Y more horsepower compared to brand Z!", that people will generally believe it to be true. Now, maybe it's the trained scientist in me (Ph.D. in Molecular & Cellular Pharmacology, studying the subtype-dependent potentiation of neuronal nicotinic acetylcholine receptors by zinc), but it really offends me that people would post such nonsense. This is perpetuated by the bozos at car magazines who do a SINGLE baseline run and a SINGLE post-mod run and claim that the 2 hp difference seen is a significant difference. These charlatan-like assertions are just plain laughable... any number of things could cause these miniscule differences (car cooled off while installing part, original part being replaced was dirty/malfunctioning, etc.) If you want to truly make claims that are at least somewhat reasonable, you need to have MULTIPLE runs with the same condition to find averages and trends. This problem rears its ugly head again when people make speculations here and there about how these turbos compare to those turbos.

(kind of rant mode off)

Personally, ive not got a clue what the graphs even mean, just thought they were nice handbags.

It is all about area under the graph though.

Peak power is good, but it's not as good as having lots of power through the revs.

 

you could have a 900bhp car that doens't do anything until 6k but then redlines at 8k. Not much point in that. :nono:

 

Graphs are a very good way to describe how good a turbo/engine/setup is.

I would imagine that the car in the second graph would deliver the power more smoothly through the rev range. Is that right or am I reading it wrong?

Mac, for someone who says the americans talk shite, to then quote them.... ah well...

 

Anyway, that quote is with regard to comparison runs to see if any product has made the gains quoted... There were several runs done and this was one of the graphs produced.

 

Anyway, there's nothing to argue about, its there so believe what you want...

The car in the first graph will pull the same all the way from 4500-redline (or near enough). The car in the second will pull harder as the revs increase...

Mac, for someone who says the americans talk shite, to then quote them.... ah well...

 

 

 

Ok first look at what cars are produced in the US? :rofl:

 

My Lincoln Continental has 800rwhp :tongue:

 

second IMHO It's the japs that know about tuning and NOT the US (ask Nico) :D

 

 

So what who cares? We all have an oppinion who is right and who is wrong?

 

US tuning? :nono:

 

Japan tuning? :dance:

 

 

So get of your soap box and buckle down to your IT job!

LMFAO and which country are the PEs from again???

Are we all having a race back from Billing then to see how they really perform?

My T28's will kick Greddy ass! :rofl:

My T28's will kick Greddy ass! :rofl:

 

LOL at least you laugh about it. :D:D

Yea wish Duffer would too:D

:rofl: there, that better? :D

Chris I found this but don't take it as fact as it was from a :x: site:D..................................

 

 

 

 

TD05-18G's and T25-28's = Man... definitely surprised me... I knew the T25-28 lag wouldn't be all that great, but to be the same as a turbo making almost 50% more horsepower is simply not acceptable.

 

Still want to race Chris? :eek:

There's not actually that much between the PE's and the TD05's, granted the TD05's are better (400bhp Vs 350bhp) but there are more factors than turbo spec.

Lower compression won't help, nor will 150Kg of body kit LOL.

 

It's good that there's some competition on here now, people might start producing some decent specced cars. :)
