so what were the A/F ratios of the before run...and what kind of timing and A/F ratio did you end up running after you cooled it.

 

Josh i'm not slamming trd with my comments; we're running the stock sc and are happy so far with what it offers as such. My "point" was that it would be nice to see TRD taking the lead on some of this r&d, coming up with mods that will work with this unit; while letting us owners know why other mods won't work or be "allowed". In the old days, when manu's said something couldn't be done, it was left to the dealers, garage owners, or even rodders to figure it out first... but then you saw their results on the showroom floor. So my hope is that TRD sees that there is real need and interest out here, and helps take these cars to the next level. I never thought this unit was incapable ( in fact i think most of us would agree it has some solid, reliable, potential to be had ); i just think that the supplier could handle the marketing/development a bit better. There has to be intakes, exhaust, bpv's, etc that will work wonders with this unit; so if they don't want the aftermarket ones attached, then by all means come out with add-ons of their own that will work for us. At least give us owners the options instead of "no.. no.. no.." Sorry for the rambling, just wanted to toss my .02 out there... after all, if this car can be fun with near 200 hp at the wheels, i can imagine the smile you guys have with 220,230, even more...
And a tip of the hat to the individuals who are taking this unit on and showing us some nice options...

 

I agree with you whole heartedly. The problem is TRD will not do this. Let's face it, there is not a big enough market to make it worthwhile to manufacture supercharger add ons. When you look at the big picture of TRD's business...it is just the truth. They developed a supercharger setup to get the most out of the tC while keep it as reliable as possible. Beyond that, they have no vision. They don't see the need. I just hope that they will allow vortech or someone to service the damn thing down the road in case peeps have problems with them while they are out of warranty.

TRD add-ons would be a sweet thing, though.

 

^^ understood, and agreed. It's just when you get a postcard in the mail from Toyota to modify your TC, and all they can show is the sc, the axle back, and strut bar.... there just seems to be something missing.
well i guess for the next couple years we'll have fun with what we have..... then when warranty isn't a concern for us, let the games begin...

 

Like PghtC said they designed the S/C to get the most out of the tC and stay reliable. TRD did tons of testing on this thing and this is what was most reliable. So far it seem that most of the "upgrades" have cause problems with the unit. Not all of them are bad and personally I don't see how changing the BPV is going to hurt. The pulley's I'm not sure about but I'm not the engineer so that is what it is. The header looks as though it is cause seals to warp. So why would TRD come out and offer something like that? It doesn't make since. TRD offers performance parts for theirs cars to run safely on DAILY basis. Not just a few 1/4 mile runs on the track. They have never really offered anything as far as an upgrade for any of their S/C's. With all the problems that have come up so far with what I'm calling simple mods I don't see them offering anything that will cause damage to the S/C. Personally I don't think your average "tuner" should even be thinking about modding anything with the S/C. Most people don't even understand how these parts work. They just see a HP # and shoot for it. Don't get me wrong I'm not directing that toward you or anyone in this thread it's just a general statement.

With all that said you also have to keep in mind where TRD is located. The C.A.R.B. & emissions laws in California are just outrageous. In order for these part to stay under warranty they have to be legal to put on the car. It took them forever just to get the ting to pass the way it is right now. TRD has offered part for some of their other cars that were "off road use only" and could effect your factory warranty. I know they offered headers for the Celica that carried no warranty and a Kazuma race exhaust that also had do warranty and we sold a ton of them. The reason they were available is because they were TRD Japan parts.

PghtC you're right to a point when you said there isn't a big enough market for them to offer parts. Trust me TRD has vision well beyond what most of us have here. But the point remains that if it isn't safe to put on the car and have it start every single day they aren't going to do it. To be honest the S/C's aren't exactly flying off the shelf not to mention the redesign that is going on so it will fit the 07 tC's. I think they just have their hands full right now.

 

If you're already running the max boost you want to run and you don't have any knock at full timing, then you should see minimal gains. Water/meth injection is really meant to take a car thats at the limit of safe operation in regard to knock and raise that limit. Either higher boost, more timing advance, or both.

 

agreed. It's just everyone's dream that they produce parts that work with the s/c to improve it...and keep the warranty. I wonder if they had any seal leaks during their testing...perhaps why they added the step about not tightening the 3 allen bolts until the charger is bolted down.

 

Actually the test cars that the guys at TRD were driving didn't have any problems. Actually they're still driving them and they haven't have any issues as of yet. If I remember correctly they're had them for over a year now.

I can somewhat agree with you about the tightening the bolts down after the S/C is in place. I'm thinking that the techs aren't following the instructions all the way through.

 

Are you suggesting that the TRD reflash knocks?


This power was gained without knock, just a little tune tweak, adding octane to the mix, and getting the a/f's in check... and dont forget that cooling the intake charge helps power...

 

The first post in this thread has both the first pass and the last one.

As you can see the a/f's for the TRD tune were sub 10 in some spots.

 

I don't think that's what he was getting at. I think he was just stating that water/meth injection are for cars with high boost and it's used to reduce/prevent knock. However in your case or the S/C case it builds a little power.

 

20hp is a little?

 

yeah it's a little.

 

yep, all i'm asking for is a little... each time.. it all adds up...

 

It's good to know TRD's setup car is running fine. Unfortunately not all dealerships install ti the way TRD knows how.

 

In the over all scheme of thing 20 hp is not alot. When you figure that you will need all the same part they had to make it. The boost cooler itself did not create 20hp. The combination of the header, exhaust, e-manage, and the boost cooler working in conjunction with one another created a total of 46hp. If you put the boost cooler on a straight stock set up with no engine management or that the reflash will more that likely produce less of a gain.

If the techs followed the instructions to the T then they shouldn't have a problem. So far it doesn't seem to be a wide spread problem.

 

yeah. Well we will just have to see what the gain is with the meth on the stock S/C setup. If I don't get to it, someone will beat me there.

 

I'm curious myself. I was skeptical about this at first but now it is seeming like the "safest" mod to built power. If it can do it on a stock set up.

 

one must be careful however...just like Nitrous, you dont just bolt this on and start spraying like crazy.

It can damage the engine if not used properly.

maybe the next FATF movie will be all about getting meth in their car instead of NAWS.

 

Exactly.


NAWS lmao
