big difference today after the car was dynoed again at a different dyno. Strangely enough the read out was far diiferent from the first a few months back. The first run today showed actual HP to max out at 115 @ 125kph. ok I guess. However the massive change after the retune was from lower end. At 70kph gained 15 hp at 90kph gained 20hp at 100kph gained another 20-25hp. Now maxs out at 139hp at 140kph. Mine being auto has made a huge difference between 1-2 and 2-3. Guys at Redcliffe Dyno did a good job. Smoother and the best it has ever run. Getting the head done in the next few months. $1500 fitted and port and polished just for good measure. I just want to see how much I can get out of it before a turbo. Turbonetics looks the goods with a ceramic ball bearing turbo!
Keep in mind with the retune it has a haltech interceptor unit as well

Timing and fuel - as it always is. It putting the right fuel in at the right time inconjuction with timing. Was really lean that doesn't always make good economy as you then have to use more pedal to make it go. Runs about 5 degree's BTDC. So really that gives about 100kw at the rear wheels. When Toyota talk about 160kw from a 4.5 they are at flywheel. You lose heaps thru transmission, particularly auto - over a 1/3 lost in fact. Kinda makes it relative.
However IMO whislt they are a haltect dealer, they have thier own unit that allows them to do more than the haltech unit can. I would check them out as well before adding any piggyback system.

how reputable are the dyno guys?Red Rover wrote:big difference today after the car was dynoed again at a different dyno. Strangely enough the read out was far different from the first a few months back.
there was a write up in various magazines years ago warning people about some dyno crowds who where inflating the figure's to make xyz product look good.
for eg someone comes in who just spend another $10k on heads etc and the dyno run shows only a few hp more so they up the figure's so the client isn't disappointed and takes his $ elsewhere. when in fact the actual improvement was quite normal for that motor with that setup.
just be aware there are tricks to every trade :(
Sure, i know what you saying. I guess I should say the big difference is in the drivability now. Even without a report there is a massive difference I can really feel now. Has some real grunt now. Having said that 139 hp isn't huge. Now if they said 230hp and drove the same i'd be concerned. It's strange that the first dyno mob said 138hp some months back but had bugger all power down low. On the first run yesterday before the tune up said about 110hp max. Now I know there has been an increase because I can really feel it thru all gears so I tend to go on the recent run on the dyno. The dyno report showed the big gain up to 110kph and I can say it has certainly done that. No point having max power at an unusable speed. But I take what you are saying though. Doesn't mean I don't want more power though.
Because I had a snorkel fitted, I went and got it tuned again. I hadn't had it tuned since I had the valve body installed in to auto which I think puts more power to the ground as it has less slip in the auto so I wanted to see what it did now as well. In any case I took it to Brisbane Tuning and Turbo Centre at Wooloongabba. I have always used them, but went to a local guy in Redcliffe the last time because it was a pain to get the car to Wooloongabba from Redcliffe. Anyways I bit the bullet and got it over there. I felt it was running rich as I could smell fuel from the exhaust. As it turned out it was running really rich. The cruiser really flies along now. It's pumping out 165 hp at the rear wheels and 736NM peak torque. A mate drove it last night to see the difference before he does the auto upgrade and ECU interceptor and he reckoned it was chalk and cheese before and after the dyno. I smile everytime I drive it now.................I just got to resist the temptation to keep planting the right foot now. Very happy. I think I have done as much as possible with out a turbo, except a reworked head approx mid next year. NEw diffs installed in Jan 4.5 ratio.
hey mate we fitted a haltech e6x on my 80 series which is manual 4.5 and we made 170hp at the wheels with standard exhaust system. its good to see that with a ecu upgrade both cars are round the same horsepower. i was going to put a turbo on mine but am opting for a xr6 turbo engine instead. what sort of kms do you get out of your car fuel wise?
about $1300 tuned. 165-170hp feels pretty good under the pedal. Economy is still about 4.5 kms per litre (22 ltrs per 100kms) around town. Picks up on the highway to about 16-17 ltrs per 100kms. At 170hp you are still looking for more power by the sounds of it. Are you unhappy with 170hp or now that you have some respectable power and liked it you want more? Can't blame you.
Had my FZJ105R GXL auto installed with a Unichip, 2.5" exhaust and extractors - dyno tuned on 91RON in Canberra not long ago, result was 104kw (138HP) at the wheels (305/70/16 tyres).
It's an auto, so it's never going to have the same sort of balls the manual has. But it also means I've got somewhere around 40% drivetrain loss which isn't pretty.
Economy sits around 22-24L/100 on ULP.
30L/100 on injected LPG with its own computer system (last run pulled 94kw at the wheels on LPG).
An XR6 Turbo 4.0L motor would be awesome... stonkloads of torque, plenty of power and breathes well...
Let us all know how the project goes!

Guys
remember the 7mgte 3 litre supra....toyota put a turbo on it and ran small boost....it was a smaller version of the 4.5 cruiser motor...thats probably where safari got the idea of their 4.5 turbo setup.....checkout avo website for a balltearer bolt on kit with intercooler.4.5's really come alive with a hairdryer...so much so, that you cant keep traction accelerating in first

i think the other biggest factor for the 4.5 with power is the pissy little throttle body and intake chamber. we are going to be putting a 90mm throttle body and re-make the top part of the intake chamber this weekend coming up, so i will keep you guys posted on what sort of power gain and economany we got out of it.
