13T vs. stock spool time.

[valmes]

I just made a video of how 13Ts spool up.

Conditions:-14C, slippery roads, but car never lost grip... unlike in 1st, 2nd and even third gear pulls. So it was 4th gear pull from low speed and WOT from around 1000rpm. Two pulls. Had to release the throttle while it was above 0,55-0,57 kg/cm2.... cause it was dark and I just didn't want to hit anything... again... :)

Here are the results:
(I can't insert images from outside - so they will be attached to this message)
Btw, I took "readable" screenshots... they are not all from one pull, If anybody wants to verify I can probably get video somewhere online.. although it's 23mb in size.

Hope anybody can do the same on stockers? So we can see the difference? ;) and may be even "single turbo guys" will chime in and let us know how their cars behave?

PS: Finally got rid of some of the bad boost leaks! ;) All with the help of "smoke machine" :) ... Smoke came outta places I never thought existed...

[Axeboy]

Interesting

I have my old rolling road readout from my last vr4.. would that help? I can take the rpm and boost off for that if you like?

[Kieran]

Smoke machine? How did you use it Val?

[Axeboy]

Reading from my graph i get:

1200rpm - 0.00bar
1500rpm - 0.16bar
2000rpm - 0.72bar
2500rpm - 0.92bar
3000rpm - 0.92bar
4000rpm - 0.92bar
5000rpm - 0.86bar
5500rpm - 0.83bar
6000rpm - 0.83bar
6500rpm - 0.83bar

[valmes]

Smoke machine? How did you use it Val?

There are differently sized plastic block off plates.. you just put one on your intake after the MAF (or before the MAF doesn't matter) and one just before the TB. Then you push lots of smoke inside under pressure :) ... It's quite easy to spot the leak when there is smoke coming out of place!

Was it with boost controller switched on or were wastegates actuators disconnected from a pressure source? Would be better to try with BC off to see the difference up to stock level of boost, but... hell... do they spin fast!!! :) 0,7 bar by 2000RPM?!? Are you sure? We will check soon with local VR-4 and same conditions...

[Wodjno]

Interesting results :thinking:

Axeboy ! What gear was that in though ??? 1st ??

[Axeboy]

cant mind Wodj, it was 3rd or 4th

[Wodjno]

cant mind Wodj, it was 3rd or 4th

That makes sense :inquisiti As the higher the gear would allow the Boost to rise higher before the revs rise to much..

I think data needed for comparison is Boost against time, not rpm :thinking: And at the same boost levels and gear :happy:

[Axeboy]

Yeah... be good to see the video

Hi Valmes

Yep, boost controller was set to 0.9bar if i remember correctly.

My current setup is similar, about full boost by 2500ish rpm...

[Axeboy]

Heres my old RR printout..

P3 is boost in Psi.

15016


Heres the torque graph, figures themselves dont mean much:

Torque, all at 2000/2500rpm:

15017

[valmes]

I wonder how that single turbo (480HP) spooled up?

[Axeboy]

Damn you valmes....

Damn you

[bradc]

Well hurry up and get it onto the car Valmes so we can see what it spools like :)

[pezza]

I detect large pools of drool at this moment in time... /yes

[valmes]

Hmmm... no that's not mine. Well, I bought some of that stuff off yahoo.co.jp, but the actuall setup was done by someone in Japan... I am still going for Twin Turbo setup. Just wanted to know some opinions on what that single can provide in terms of spool up...

"<The vehicle details which are removed>Mitsubishi [regunamu] VR-4 year type H10 year type EC5W (LNGF) under carriage number EC5W-00130** grade VR - 4 colors №T08 (the purple) * it is the part which is removed from the car which remodelled the VR4 [tsuintabo] 5 fast cars to the single turbo. <Commodity explanation>It is the used item of the HKS GT3037 turbine.

Buy It Now option?

I did a couple runs today to compare with Valmes 13T spool time.
Run1, from 1000rpm in 4th gear... .57 kg/cm2 @ 3000rpm approx.
Run2, from 1000rpm in 4th gear... .61 kg/cm2 @ 3000rpm approx.
Stockers rule for instant boost !!!

[Madhav]

Can't quite see the RPM side clearly on the video, looks like you start off at 2500rpm? Can you make one in high quality?

2500 .5 bar?
3000 .8 bar?
3300 1 bar?

Can you clarify?

[Madhav]

Here's mine with the KKR 280's, this was with only very light throttle though as the tune was set for stock turbos, i.e. absolute max boost asap, so at like 1/4 throttle the boost controller went nuts, you will see the video, it's not really accurate, but anyway there it is, if I had given full throttle I don't know what would have happened??

It was in 3rd gear going up a very steep hill with temp at around 30C degree and high humidity....

Also attached is the dyno readout 'post tune', i.e. with the boost controller turned off completely. So the video is pre tune, dyno is post.

[valmes]

its 0,5 bar by 3600-3700
1 bar at around 4000 rpm

I will make emu log to get more acurate numbers.

i have a question about your 13T setup,

was the stock exhaust manifold outlet port matched (bored out) to the subi turbo inlet size?
or did you leave the stock manifold untouched?

[valmes]

TD04 - stock manifolds.
TD05 - ported to match the turbo exhaust outlet.

[Gly]

do you think there is any gain to be had if you had port matched the td04s?

[valmes]

do you think there is any gain to be had if you had port matched the td04s?

On the contrary, I think stock manifolds gave me better spool up, but sure they would flow better up top if ported.

Passenger and a bit over 1 bar of boost (aka RSM Dyno):

1.4 bars makes a difference:

Found this spool chart on the 3000gt forums, so now we have a benchmark, well almost as their engines are a little bigger, but here it is anyway.

I added my KKR 280's in there also, they're in black, they are hitting 9psi by 2550rpm which actually looks ok by their chart in comparison, this is with the boost controller turned off completely...


I'm kinda hoping once the boost is turned way way up to max it will keep spooling quickly from there and up to like 18psi at 3700rpm or so, if they do it will look something like the second chart

[Louis]

looks pretty good compared to others

[Madhav]

I just hope the second 'predicted' chart actually turns out like that.... I will find out in a few days.

what fuel do you use?

[zentac]

That was on shell V-power (pump ruel)
New cams going in this week so that should help us hold the boost longer.

[Turbo_Steve]

Has it actually been mapped for early spool? Seems to build VERY quickly between 4000 -4500rpms...just wondering how it's setup.

If found larger turbos can sometimes be spooled by running stupidly rich once it's making SOME positive pressure: it increases the charge density which helps turn the turbo. It does cost power, though, however sometimes you can make it up with a little advance, but more often it is compensated for by the car being on boost quicker!

You only need it in the higher load-points anyway (don't want it bogging on light throttle) however if the pedal is down and it's waiting to spool a "hump" in the fuel map can sometimes make all the difference.

[Madhav]

A new chart with boost turned up in comparison to the 3000gt dudes.
