What setup are you running? any sound clips ?

 

turbonetics....dont know how to upload the video...any help?

 

^ seeing as this relates to people with the supercharger, that turbonetics video wouldn't help all that much...

 

^^seeing how the guy asked me what set-up I am running..I dont see your piont....

 

the thread is related to the supercharger, not a turbonetics turbo kit. he might have thought that you were supercharged with a 3 inch exhaust, hence why he asked you what setup you are running. in your profile you have no parts listed or anything. i actually thought the same thing, that you had a S/C. that's why I am saying that your video with a turbo kit wouldn't help people with the S/C...

 

oooo...gotch ya...sorry

 

progress on Scion Life!!!

 

 

Sorry I thought you where s/c ed and wanted to hear a sound clip of a s/c

 

really nice to see some new R&D going into the old TRD S/C, i applaud your efforts and like seeing new stuff like this.

but since the car still has its stock, cat'ed header, it isn't a fully inrestricted system yet is it?

so how do you think this would effect a tc with an aftermarket header, leading into 3 inch exhaust? maybe then with a 100% unrestricted exhaust system there might be some loss of power at the lower end. which is when a 2.5 inch exhaust might shine over the full 3 inch.

 

You are correct it's not a fully unrestricted system with the factory header and closed-couple cat. But we we're refering to the header back in regards to "exhaust system".

Only one way to fine out for sure is to dyno a tc with a TRD S/C running an aftermarket header and 2.5" header-back exhaust system and then switching out the 2.5" system for our 3" system.

 

I would like to hear a sound clip of the 3" full exhaust with an after market header, I remember someone running 9.5 pulley getting a 21whp gain with a strup header alone.

 

nice numbers
now to find sound clips and compare....

 

I don't know if this helps any but my dyno with header-spipe-exhaust all 2.5" at 8.4 psi was 224HP AND 196TQ on a mustang dyno....

 

any chances of getting a dyno of the 3" with a header ?

 

I know the guy who let Ptuning use his car to test the exhaust. It's very unlikely that he will put a header on his car.

 

can we get a sound clip? of the one you tested without a header.

 

Sorry, we were so busy dyno testing the exhaust system on the TRD S/C that we never got a chance to get a sound clip of the exhaust system. But we can tell you that it does not sound any louder than a TRD S/C with a stock exhaust and TRD axle-back.

The muffler we used on our 3" system was custom-made inside and out. The noise-reduction with the production muffler is far greater than even the prototype muffler we used in our original exhaust sound clip. We did installed the 3" production system on a customer's tc with a Greddy turbo and took it out on the road and it sounds fantastic. There is Zero droning or resonance with this system at idle or at 40mph or even 65mph crusing speeds. This is the last system you will ever need to purchase. You get the best of both worlds; a system that produces power without making a lot of noise.

Once we get a hold of a tc with a TRD S/C and an aftermarket header, we will test out the 3" system on it again and we'll try to post a video w/sound clip.

im sure plenty sound clips will show up as the release is rolled out.
but either way what you just said about it is very promising for what i like.

 

I just thought I'd chime in since I took the lead in designing the exhaust system as well as performing the dyno testing and tuning.. Btw, it's nice to have the two go hand in hand when designing power producing performance parts.

We've received numerous requests from SC'ed tC owners asking for a 2.5" header back system since we first announced the release of our 3" system for turbo owners. We had the idea at first to eventually release a 2.5" system for SC'ed cars, but in lieu of the recent dyno tests I'd have to say that it probably won't be necessary.

Even at the factory TRD-set boost levels, the tC we dynoed showed noticeable improvements in top end performance over the stock exhaust w/TRD axle-back. More importantly though was that, not only did we not lose low end power with the 3" exhaust, we managed to see gains from off-idle all the way until redline. If the TRD SC'er was of the blower or screw type variety (aka Eaton SC), I'm sure the gains down low would be even more dramatic.

Needless to say, I'd expect SC'ed owners with higher boost pulleys to see even more dramatic gains in power. On another note too, it seems quite a few tC owners we talked to at various show/events expressed interest in eventually upgrading to a turbo set-up later on down the road. This system makes sense since you will not have to upgrade to a full 3" system down the road should you decide to make that change.

As for sound, it would be difficult to describe the exact sound levels with words. However, as many of you know, we deal with all different types of forced induction cars on a daily basis. I can assure you that this system is by far one of the quieter 3" system of any kind for any car for that matter. Yes, the ultimate test will be on a SC'ed tC with a header, but I honestly don't expect it to be much louder than a typical 2.25" or 2.5" header-back system. Had we not run out of time for testing, we would have put together a sound clip for the SC'ed car. I'm sure we'll have local SC'ed owners, hopefully a few with headers too, install this system. In which case, maybe they can post sound clips up first. If not, then we'll conduct some further tests soon ourselves.

Thanks for reading. Happy holidays!!!
