Zr6 supercharged

Zr6 trd aurion DYNO

Recommended Posts

Hi All,

This is all good and very interesting. I saved the dyno video (right click save link as) and watched it and 210kw is pretty good for the modifications you have done. 

My TRD Aurion stock standard was 190kw at the wheels, again different dynos and day.

You mentioned that you changed the pulley to a 2.55inch roughly 64.8mm - I think the stock one is approximately 70-75mm? 

Did you purchase the Monkey Wrench Racing Pulley? and which workshop in NSW pressed your new pulley on?

The TVS1900 is the correct supercharger to be bolt on. I have been told that the larger supercharger will compress more air. It is also a better solution than reducing your pulley diameter even further.

Most workshops can now tune the TRD Aurion ECU's, are you going to run a flex fuel sensor? so you can run E85 and 98ron as well?

If you are going to run E85 only then I would recommend upgrading your fuel lines as well. 

One question with your Varex Muffler did you have it completely open when on the dyno? 

I'am looking forward to seeing your results.

are you still going with the e85 option, 

Yes that is the plan just waiting to get the tvs 1900 first so it can all be tuned and not have to tune it twice.

before I did wheel tyre suspension change I was keen to put the lsd in, axle tramp was terrible didn’t mater how smooth the surface was, with heavier springs and adjustable dampening I can dial it out, and set it back to comfort for normal driving. With the right combo the ebd works well for simulating the lsd for straight line acceleration, always got to be cautious with cornering don’t give the front wheels to many tasks, 

So so what kind of suspension did you go with to help with the straight line acceleration your saying ? Also how much will an upgraded torque convertor really help with getting that power down to the ground?

Hi mate glad liked the video.

Tbh not to sure what the standard size pulley is but i think around 70mm. The 2.55inch pulley it something i purchased from a company in america called URD they specialise in all kinds of pulleys for supercharger kits mostly trd ones.

It is a stealth 2.55 inch pulley but the pulley was not made for our supercharger as it is only a 5 rib pulley not and 8 rib like ours. Although it still fits on but it  requires the drive belt to be sliced so taking off a.few ribs. As for prrssing it on i did it all myself they give you like a diy kit which comes with a snout shaving tool and a press tool to get it on but u will have to find a clamp tool yourself that removes pressed on pulleys i bought one from supercheap. I have just removed that pulley and have the belt also that i sliced if you are interested in it i got one custom made that is 2.55 inch but the standard 8 rib which cost me a fortune wish i never did it same results as the 5 rib 2.55 inch and i plan on the bigger supercharger so kind of lost money there. 

 

As for e85 yes the plan is to have a flex fuel set up.

 

When you say most workshops can now tune the trd aurion ecu can you name any ? Because i have only found sas performance thst say they can it would be good to be able to shop around.

As for the varex yes it was fully open and traction control turned off by me and the rest was with the tuner 1st run was 190ish then 208 then 210kw.

Awesome, thanks for the pulley offer, but like you I will probably go for the TVS1900 instead.

I have been told that the larger TVS1900 supercharger will push more air at a similar temperature to the 1320. I was recommended not to go to a smaller pulley as it will spin faster and compress more air, but the air will be hotter going into the engine. 

Sorry I assumed there should be more workshops that can tune Toyotas in Sydney.  I have found one in New Zealand.

I have had the company below reflash a trd map onto a stock Aurion ECU before. I wanted a backup ECU but it didnt work as the TRD ECU is actually different to an Aurion ECU.

Advanced Tuning were pretty confident they could reflash my ECU and quoted me $1500NZD, and it would be across 3days.

I think alot of workshops just can't be bothered to work on the TRD Aurions ECU.

Gday the suspension I run is bc coil overs, I have heavier spring rates in the front, can’t remember the number, still looking for the paper work. Wheels are Koya sfo1( basically an enkei rpf1) 7.9 kg for an 18/8, tyres are nito invos, this combo has made the difference for me on stock trd, changing the dampers and the heavier spring rates along with the higher side wall as well as  reducing unsprung weight have helped with straight line acceleration of the line.

Not sure about the torque converter, was not my suggestion, can’t really see any gains of going high stall- the gearing is pretty good, I’m looking into the valve body, this can be removed/ fitted without removing the transmission, I’m waiting on a tuner to see if they can rework the ecu,

What kind of results did you get after the trd ecu was reflashed ? Did it make much of a difference?

Tbh with you this info is abit technical for me and im not exactlt sure what half of it means. Let say i leave stock wheels and tyre size and go for bc coil overs will it be able to be adjusted in a way that will give the car better acceleration? Also how hard is it to adjust height for the rears ?

 

Another thing i want the maximum torque and best take off without having to go for the lsd because it will cost to much and labour ripping out gear box and all. I thought high stall torque converter would help get the power to the groud more. Also mwr have a valve body but it says for 5 speed auto trans is that a mistake on their website or will it work with the 6speed autp that we have. If so that in conjuction with the converter should make a good difference it getting the power down to the ground or would just the valve body be a better option

gday yeah adjusting is a simple as turning a nob, the key is getting the right spring rate (suspension shop will help with this), with coilovers to adjust the height the bottom mount screws up or down for both front and rear , the spring travel is always the same amount regardless of how high or low you set the height, unlike lowered springs which lower your car through reducing your spring travel, you can also align your wheels properly with the top camber,

gday Adam, any new progress, I changed my y pipe, exhaust and intake, I went with 2&1/4 to 3 inch merge 3 inch all the way to a 3 inch varrex, used ssc intake kit, awesome sound, vsc system check came on,

Hey mate yeh abit of progress i got the tvs 1900 superchargee hoping to get it installed this weekend bought it from ssc in artamon so its pretty exciting. Then maybe in the next week or 2 planing to do a flex fuel set up and get it all runing properly. Just not sure whats the cheapest and best options to do to get the extra power down to the ground its kinda useless if its just going to wheel spin all the time u want to be able to actual feel all that extra power otherwise no point. But things just get very expensive fast so thinking either the high s trall torque convertor or the valve body or maybe just going coil overs not sure whats the best bang for buck if someone could give me some advice on that would be great. Congratz on the exhaust did you go dual varex or just single ? Also not sure y ur vsc light came on when i installed my k&n it was all sweet no lights came up maybe try take the battery off for a few mins to reset the ecu ?

Cool nice work with the tvs 1900, coilovers definetly help with traction,  a larger sidewall tyre also helps(18” wheel ), I went with the ssc intake, it’s my exhaust that’s throwing the vsc code, my y pipe is too big for the sensors ( more flow) I went with a single 3” varex muffler, I’ve got a scan tool to reset the ecu, I can’t find anyone to tune the ecu in Melbourne, I might have to road trip it to Sydney or go stand alone, $6500 for Motec or $4500 for haltech. What diameter pipes did you use for your y pipe 2.25 to 3” merge is the sizes I used. I’ll be keen to see how the standard ecu performs with the larger super charger, keep us posted

Absolutely loving this thread, really keen to hear if the TVS1900 gives a bit more of that sexy supercharger whine over the TRD variant.
Dumb question about the coilovers - you can get them without the car being lowered? I love the height my ZR6 sits at compared to my old TRD, and wouldn't mind upgrading the suspension to combat the occasional axle tramp so long as I don't lose any of that height

Having stiffer springs and adjustable dampers definitely helps for traction, but it won’t overcome corrugated roads, my ride height is very similar to the Trd stock height with coiovers I still have adjustment to raise the car, or lower, I don’t have any clearance issues with the height I run, the suspension that was on the car when I brought it was Kyb struts with lowered king springs, this was a horrible combination, the lowered springs reduce your spring travel and u end up riding on the bump stops, it also had lots of clearance issues,  driveways, speed humps and just driving along the road, would foul

Gday all, another thing to look at in regards to traction and axle tramp is the engine mounts, due to to the east west configuration of the front wheel drive the natural twist of the engine changes the center line of the drive shafts, changing to neoprene engine mounts stops this twist, which helps getting the power down, trade offs are more vibration through the chassis, but it will be worth it as it’s a lot cheaper than an lsd

Yeh dont really want to make the car have more vibrations already with the exhaust and mods it doesnt feel as smooth as stop and i dont think it would help anywhere near the same as a lsd would it ?

UPDATE!! New tvs 1900 supercharger has been installed for almost a week now just havent had time to post it up.

Let me say it was not an easy job at all and alot there is a fair bit of modification required as  the supercharger hits the bonnet just slightly. The hardest bit of the whole job was to get the manifold off the original supercharger once manifold was off the car. It is held down with allen screws that are very tight and the moment u try to put any kind of allen key on them it just threads the heads. Had to end up drilling them out which took hours to try and not damage the manifold because the angle of which you habe to sit the drill to try and cut away at the screws is just a painnn. Bonnet had to be cut throttle body adaptor on the s/c had to be fliped intake modified and a whole bunch of hoses replaced for longer one. Dont get me wrong the car feels good now some more power there but without a tune yet the car i feel just wants to detune its self. I also ended up installing a boost gauge which im happy about i managed to drill a boost tap into the manifold while it was off the car so wen im pushing it foot to floor gauge is ready 10psi thats with a 90mm pulley i also have an 80mm pulley but will prob install it wen i go to tune it. This was all done at my place mechanic came past and i was helping him with what i could. The new s/c was powder coated black colour i ended up paying some high temp spray paint and sprayed it red its abit patchy now coz some of the paint got scratched off but ill touch it up. surprisingly the colour is very very close to orignal. I also got my hands on an original trd s/c decal wasnt cheap!!! But atleast it will handle the heat.

Very nice! How much power is she making now?

Tbh not sure havent got it dynod yet.

 

As for the price it was bloddy expensive for what gains u get i think but i think once smaller pulley goes on with a e85 tund will be worth it. Cost around $4200 all up with labour and all the little bits and pieces.

Oooof, that's one sexy unit!
Is there a noticeable whine when you give it the foot?
