Dont know the specs of most of the exhaust system, I hope to rip off the heat shield and have a look. I dont think it is getting much cold air though :S I will update this on the weekend. I assume the ratios are pretty good seing as it was tuned two days ago, and they said they mad it a little leaner than normal.

My Gen 2 3S-GE with a HKS filter in the standard airbox, unknown 4-2-1 extractors put down 94.1RWKW a few dyno days ago, should rev happily to 6500-7000RPM, I never really pushed mine any further but it should go there OK.
Here's my dyno chart if it's any help...

Also, I was trying to take the heat shield off the exhaust today, damn that thing is on tight, does it really do anything? Are there any rwd extractors out there for the 3sge or is it going to be a custom job? as far as I can see with the shield still on the primaries are very short, only two pipes emerging from the heat shield.

The heat shield is a bugger to get off, and I've never removed it  You don't need to get at the oil filter, you can just fit your hand around it.
As to the extractors, were already on my car when I bought it so I can't give you any info there. I've not heard of any extractors for the RWD config of the 3S-GE, but there should be as it's a pretty common engine.
Original exhaust is quite restrictive, primary's are very short, and the mods previous owner of my car made seemed to make quite a different from stock power levels, that said the Gen 3 sh*ts all over our Gen 2's putting out abuot 105RWKW stock...

Yeah I got my filter off last night, was fine, just want to get a better look at the extractors. I am pretty sure that my idle air valve is buggered, it doesnt close properly. eg when the engine is hot I pinch the hose and the car stalls, afaik it should do that when cold but not warm, anyway a few more mods before going back to the tuners. CAI of some sort, get the exhaust looked at and replace the IAC valve with one of a rb30 or falcon. Maybe even look into quad throttles depending on expected cost, would be nice to get going.
Any input fellas?

I am beginning to think that the cat or muffler is blocked, is there an easy way to check this? The reason I think it may be blocked is that I have replaced the gaskets between the primaries and secondaries and sealed it up real good, and now the join between the cat and the secondaries has gone. I thought it might be a bit unusual for both seals to go in such quick succession, any thoughts?

Could be a bloked cat or muffler, you need to pull them off to check, as for rwd pipes for a 3sge i doubt it, if you do need a set of pipes hand fabricated feel free to give me a call as i do this sort of stuff for a living, and can be made to whatever specs you want.

Awesome, sounds good, because as you can guess rwd 3sge manifolds dont really grow on trees and there are some pretty nasty clearance issues. I will check the muffler and cat and once I come into some more funds I will give you a call.
Anything I should be looking for, I have never looked at a cat or muffler before.

When you pull the cat off you need to check the biscut inside for melted over honeychombs, broken up etc, should all look clean and undamaged in anyway. as for the muffler if its straight through or centre-offset straight through you can generally see through them, if it is a baffeled muffler (triple flow etc etc) belt it with your hand and listen for loose baffels, generally if it rattles its on its way out.

Ps: I have a 3SGE rwd manafold tree in the backyard, due to start fruiting soon!!!! He he

As far as I can tell my exhaust also has no flex pipe! I think this might be a bit of a factor in this. The cat is more or less stuck to a long length of pipe so I will need to get me a nice light source to check it out. I am not sure what type of muffler it is but it doesnt rattle.  Leading me to believe that it might be the cat that is fucked.

I didnt do that work, it was performed by the previous owner, how can I tell how it was blocked up? This will all go if I ever managed to get towards one of my dreams... quads.

Just a thought.. If you disable the ACIS system in its closed position (just plugging the hose), the curves will look something like yours.
Opening the ACIS butterflys definately improves the breathing in the >5000rpm area.
How did you disable it, and more important WHY?
|
I think I have found where it is blocked up(and it is blocked up) what should this tiny little port be hooked up to?

Well the diaphragm is supposed to be hooked up to a vacuum switching valve, which is hooked up to a reservoire tank, which is connected to one of the three ports on the manifold..

Download the two toyota EPC disc images near the bottom of this list: http://www.yankeetoys.org/Docs.htm
Then read the FAQ and install the EPC (Electronic Parts Catalog). It's an old version of the software that the toyota dealers use.
It has been very helpful to me sometimes.

Nope... never got as far as modifying the setup before I sold the car... But as soon as my SE82 is on the road I will get right on it.
To find the right opening rpm, you really just need to do two dyno runs. One with ACIS fully open all the time and one with it closed. Then compare the torque curves and find the rpm where the curves meet.

I am assuming I could simplify it somewhat on Toyotas design, just a valve(controled by RPM) that is hooked up between the port on the intake and a vacume line.

I have some pics of the intake which I will post up once the server I use comes back up. If anyone has an idea on what it should look like please post that idea.

they will rev ok to 8000 rpm but dont go any further ,the trouble with the wolf conversion cause the guy that did it was 1 of the wolf founders is the inlet is shit you need quads to get some power out of these also the extractors are 2 small you will need either 1 3/4 or 1/7/8 '' for you primaries

Yes trying to go large as possible with the extractors, but space is very damn tight, will keep you all posted on how it goes.

Well, it seems to be all good, the car is breathing well and sounds nicer too, the exhaust shop said that I might have a chunk on cat in my muffler so I will be checking that puppy out sometime soon, through this I have also discovered that I dont have AVIS at all, its been hacked off(thanks for all the help pugho). So down the track I think I will attempt to get some 20v quads happening to solve the intake side of things.
Cheers for all the help dudes.
