Hilux 4x4 Forum

Lyk my Schalk sy naam en werk loop hom vooruit
Die plan is om so binne die volgende twee weke self ook daar by hom n draai te gaan maak en uit te vind of hy ook my trok sal kan toor
Sal sodra ek dit gedoen het graag ook my dyno chart hier plaas

Bennie ek sal jou laat weet waneer ek kom dalk is daar tyd vir so n draai daar in julle speelplek as Schalk sy ding klaar gedoen het of hoe ?

Cool laat weet maar

Hi
Het toe gister my hilux 2.7 by Schalk gehaad , En ek is beindruk die bakkietrek beter en voel beter .Ek het nog nie na die brandstof verbruik gekyk nie maar sal julle op hoogte hou
Hier is die dyno cart na die dyno

Yis Okkie ek is bly om te hoor, moet sê 100HP op 33 Bande is impressive

Oupa se Dynosheet.

Lyk darem heelwat beter as die Mr Turbo syfers.
Kan nie wag om die ou te ry nie.
Dink hy gaan nou bitjie minder sukkel om die 33's te rol

Sal more haar oppie Highway vat en jou laat weet. Net eers Prozaks drink want daai ding se brieke isssie lekker nie en dan bumpsteer sy ook maar so biejie. Dink jy moet haar maar volgende maand by Louis uitkry vir shocks/steering damper en miskien jou steering box opstel.

Bennie, ek wou nuwe shocks mos opsit, maar ek vir Louis gese ons moet dit eers op ys sit, laat ek eers jou rekening kry.
Daai steering damper is opgesit die dag voor hy na jou toe is, maar dis n cheapy.
Wat bedoel jy met steering box opstel?
Hy moet nuwe brake pads voor kry, want die voor as het mos gelek, en daar is n paar maande se olie in daai pads ingetrek.

Ek dink daai brieke kort dalk 'n bloei ook en die steering het speling op.

Probably the drag link, Bulldog had some play in this too, but a good vasmaak fixed that.

That was the very first thing I fixed on Oupa

just did major service and dyno, still no major issuess, on 160 000km, no turbo issues

Reg julle almal

Hier is dit nou , Ek het die naaweek kaans gekry om te sien wat die brandstof verbruik is na die dyno.Ek het die tenks Saterdag oggend altwee vol gemaak tot bo (EINA) , So plus min 460km ver gery teen n gemiddelde spoed van 115km/h en en toe weer vanoggend vol gemaak tot bo (NOG N EINA)en siet daar 64L . Gou die som gemaak en dit is amptelik .... 7.1Km/L

Nie sleg as n mens in ag neem dat die 33'x12.5 bande deur die wind sny soos n plaas stal se deur, deur n suid-ooster nie ne

Nog maals dankie Schalk, Jy mag maar

Okkie

Cool

Hi All,

At last the first Kaapie EFi conversion went for the big dyno... but before we get to those results... a small story...

About 1.5 years ago I had my 4Y engine rebuild by 'professional'... the engine never performed(51kw ) at all after the rebuild, turned out the valve timing was out 2 teeth... with the carb on and valve timing fixed... here is the dyno chart(78kw Carb, Brospeed Cam - Exhaust, 245 Tyres ):
Then due to some other issues and errors on the engine rebuild by the 'pro's', I decided to rebuild it myself Jan this year...

On Monday I had it dyno by Izak at DynoTech... vehicle spec - 2.2 EFi, re-degreed brospeed cam and exhaust, cold air induction mod, 33inch MT Kumho's... the first set of results are from my attempt to road dyno it... besides the increase in power, the fuel consumption has improved. Bennie she is producing 69kw(93bhp) on the wheels... and the results...
B

Wow 93 HP on 33s :!: :!: That is excellent

Here is my 4y EFI dyno chart.I see it only start measuring from 2500 rpm
I was actually hoping for more.I have attached screenshots from the new maps.Bennie or Bret can give their opinions on it

Thanks George

I'm taking mine to Feroli's just nou too

(once the pesky kids have gone back to school)

How much was it asblf :!:

How much was it asblf

Hi Rich
R950

Hi George,

I did note that both maps state: Run 1 Before... does that mean that this is pre dyno stats? Maybe they gave you the wrong readings?? The figures are respectable, @78kw and 197nm torque... the big questions is how does she run now??

See what Benjamin has to say mos :problem:

Those Charts are not clear to me and why only from 2,500rpm: :problem: :?

were they now scared to change the ICV IGN settings you got there

I did not gain any extra power after Robbi finished tuneing.Your map was not to bad.My motor was running to lean and it was pinging and that is now sorted. Another interesting point is that Robbi says his dyno machine is very conservative. :?
She feels pretty smooth.

To Rich.Do not watch will they do this.Your heart can skip a beat.

George

I gave your maps a quick over and I did not see anything funny, except at -0.86Bar at 4000 RPM the value is set to 250m/sec wheras the fields below and above is set to 0m/sec. I do not know if the dyno guy just missed that point (most likely explanation) or if they do it for some funny reason I do not know about.

I do not know if you know how the fields work but for the benefit of others let me explain. Obviously as your engine speed goes up so you will reach higher values on the map (both the Fuel and RPM map) Your Manifold Absolute Pressure or Throttle Position (if your system is set up to use throttle position switch) will move the set point in the engine map to the right. So at idling the set point the ECU uses will be towards the bottom and the left and as you step on the accelerator the set point will move right (based on how deep you press the accelerator) and move up as the RPM increases.

It is normal to set all values at the far left ( -0.99 and -0.86) above 1750 RPM to zero. You will reach that set point in your map whicht is set to 250m/sec, if your engine is revving at 4000RPM and you take your foot off the accelerator, like when going down hill. If you reach that point in the map you might experience a slight backfire. If that happens simply set that value to 0 as well.

I'm happier for that explanation

Tar Bennie

Ps... so my mouter is doing a fair bit of pop-popin when I lift my foot; is that a case of changing the values to Zero

:D Ek kry nou so 6.5 km/l. 2.2 efi met 33 en so 6 duim lift. 110km per uur. 70% oop pad. 30% stad. Wat dink julle? Sleg of goed?

Hi Deon,

It's all relative! I've got 33's, running EFi 2.2, I get about 7.5 on the open road at 110km(odo speed)... if I drive a little faster the fuel consumption drops quickly!

Offroad the 33s are great!

B

Deon

Jou verbruik klink omtrent reg vir jou hoogte en wiel groote. Bretton se wa het ander cams en head jobbie en kompressie is nie standaard nie teen 110 idle sy bakkie amper net daar onder by die see.

Rich

Check your map on the laptop next to you on the seat when it happens and see where on the fuel map are you getting it.

Bennie,

Enige idee oor hoe om die 4Y by 8km/l verby te kry. Dink so 10km/l sal nou kan werk............

Haal you bladvere uit in sit hulle onderstebo in. Dit behoot you suspension met so 150 -200 mm te drop en jou windweerstand aansienlik te verlaag Jy kan nog ekstra laagtekry deur 'n SUA (spring under axle) converion (omgekeerde van SOA) te doen, onthou hoe laer hoe beter, jou bakkie moet laer wees as 'n Danville Golf met coilsprings wat in die helfde gesaag is.

Kry vir jou 13"rims met 'n adapter plat om dit te fit op jou trok met 155/75R13 tyres wat jy teen 4 bar gepomp hou en hou jou engine olie op die minimum merk.

Dit alles sal jou so 13-15 km/l besorg as jy baie mooi ry. Jy dink ek joke oor die tyre pressures en olie vlak, gaan check maar biekie wat maak die ouens by die Total Economy Run.


Dan as jy extreme wil gaan knip 'n halwe winding af van elke valvepring en skuur .25mm af van elke piston af en .002 mm van jou crank bearings af om die wrywing in in you engine nog minder te maak en verdun jou engine olie met 20% per volume 3 in 1 naaimasjien olie en gooi ATF in jou ratkas transfer case en diffs. Dan sit jy 'n baksteen agter die petrol pedaal of bring haar dat ek die diktator rev limit op 2500 RPM sodat jy nie iets breek, piston slap of valve bounce kry nie en ek sal jou 25-30km/l waarborg.

Of 'n makliker opsie is koop 'n Jonway scooter

Bwahaha. Ek het net my Bumper van 6mm plaat gebou. Sou nou ry ek altyd afdraande

Deon

As jy daai bumpers hier by my kom afgooi wat jy nou al so lank saamry sal jou bakkie ook ligterwees en beter fuel economy achieve

Here's mine, done at SAC in Centurion.

And yes, don't laugh it's slow, but it's mine.

:)

OK, hier is my 2000 Model 2700i se chart - ek sal solank kyk hoe vergelyk hy met die ander. Die Chip is 'n C-type Dastek chip en soos julle op die chart sien - dis Schalk wat hom ge-"tune" het.

Hennie

Probeer gerus vir Robbi by ferroli's So lyk my Chart

Charles... are u on the other side of the world? Cause when I open the PDFs they upside down... or did they dyno the vehicle on it's roof?

@rusty - Hope this is better.

Die new and improved Oupa

Bushwacker wrote:Bushwacker (3.0 KZTE with Sac conversion)se Dyno sheet. Ek kry ± 160 km meer per tank en die rook is minder na die storie.14.6 Kw meer en torque op met 32 Nm, gedoen by SAC in Centurion op die 4de Julie teen R850.00.

Hey Piet, What did you do with the SAC conversion.
I had the Intercooler / freeflow / ECU Chip and sportsflow airfilter fitted.
With my last Dyno i had 360NM and 97Kw. I'll look for my dyno chart. But it's due for a re dyno with the next service anycase.

Bennie, my 2.4 will be done next week (OEM intake & dicktator too) so will be interesting to compare the figures.

Hi Bennie,

Wat het julle gedoen om die ekstra krag te kry?

Riaan het die mouter laat overhaul en ons het die backyard mechanic EFI manifold vervang met 'n OE Toyota 22RE intake manifold.

Hier is Jaco Versveld se Dyno Sheet

Baie dankie.

Jy en Louis het 'n baie netjiese job gedoen.

Thanks

BenHur wrote:Hier is Jaco Versveld se Dyno Sheet

Jaco that very good torque stats for a 4Y... lekker!

Have you got to drive her yet??

mr b

Thanks, that is with 31X10.5X15 tyres, but the torque comes at a price - as you can see the odo overreads by 15%...

Nope - didn't get the chance yet to drive Mufasa, but I am like a small child hearing an Ice cream van.

Bennie still has to do a bit more of his magic, and Louis has to sort out a whining diff for me first.

RustyRod wrote:Jaco that very good torque stats for a 4Y... lekker!

Hi Guys,

I struggled with the 4Y in my 1991 SFA Hilux due to high wind resistance and 33" tyres. At any hill it would slow down to agricultual speeds. I was not happy with that but loved the vehicle anyway.

After much pondering and re-allocation of funds (!) I went for a Lexus V8 conversion and I'm very glad I did.

It's like having a new vehicle. As it's my only vehicle I use it on the road a lot. I'm upgrading to 35" inch tyres cos it will be better off-road and also so that the gearing will change making first gear (it's a manual box) longer and more useful. There will be less wheel spin as well!



I didn't have a dyno done on the 4Y but the V8 had one, after fitting a larger bore exhaust system and cone air filter to help it breathe better.

Tapster wrote:
and cone air filter to help it breathe better.

You must reconsider that, cone air filters are only good to filter out 19mm and bigger stones, birds, very large insects and small pedestrians, as for dust it goes right through. Offroading dust will eventually kill your engine with a cone filter, rather get yourself a bigger cyclonic filter.


Jaco

Ek het haar vandag so biekie vir 'n draai op die snelweg gevat. Goeie nuus is dat sy kan met redilike gemak 140km/h (of dis wat ek skat so teen 160km/h op die speedo) hadhaaf. Ek kon haar even hardloop to waar die naald teen die trip meter se reset pin vassteek.

Die slegte nuus is dat nie net jou diff sing nie maar jou propshaft vibreer ook. EK sal nie worry om die crown wheel en pinnion te vervang nie, hy raas nie sooo hard nie, vra Louis net om die backlash reg te stel en eerder na jou propshaft te kyk.

Took the Cruiser in for a dyno yesterday.....

Not to bad for a 94 model I think. Thinking of putting in a chip later this year.

Well guys... finally here we go.

Uiteindelik, kan ek my trok sin ook opsit en trots voel. Schalk jy is 'n ou doring!!!!!!

Het van Doornpoort Nelspruit toe gery en man trek sy lekker.

En hier is die Buffel sin ook nou uiteindelik!
Hy ry soos 'n nuwe lorie

Hannes... Cool! I take it those stats are from the direct rear wheel measurements, not the flywheel estimates... else there is something wrong??

49kw and 112nm torque

Mr B

Thats correct Mr B taken on the wheels.
I've Heard you can add +- 20% to these fiqures to get an estimate reading on the flywheel.. is this correct

Dadz is finally going for his Dyno 2mrw

(better laat than never mos)

SAC vanderbijlpark did my truck and you can see output on the wheels increased from 86 kilowat
to 111 kilowat

Jeepers wish I'd taken Dadz for a Dyno months ago - she's driving lekker nou - flippen smooth and quiet power band

As suspected she was Leaning out bigtime with throttle and the timing wasn't too good up there either. :shifty:

(no wonder it wouldn't drag-race in the Dunes)

Not sure how I'm gonna scan in the chart but Stats after Dyno is:

On Rear Wheels Only - 66.7kw, 162 Nm

Not bad for a Chinky Chonk I guess. :o

Will tyde me over till my Project Motor is built :razz:

Ps... no scan but I did take ........Peekchaz

Rich, scan the dyna report and save as a PDF file, most scanners can do that. If not, as long as you have the jpeg or whatever on your computer, try printing it as a PDF file. You can do this with the superior Open Office Suite (free) or by downloading and installing "PDF Creator". Then just select PDF Creator as your printer and Bob Mugabe's your uncle!

Cool Rich glad your happy with her.

180 000 km major service and dyno, nice to see above toyota factory spec.
