How could the HKS be too small? It has 60mm (2.36") piping which is only .14" smaller than the APS 2.5" dual exhaust. Unless somebody proves otherwise, I would assume the HKS can flow between 500-550whp.

 

I don't think you can produce that much power with a single
TT.. then again.. I've heard somebody running around 500whp with a supercharger.

that'll be cool and da gang.. I need to cut corners and salvage as much parts as I can. but I may go all the way to mid 600.. I'm ready to eat top ramen for rest of my life.

 

Yes you can. It's been done on custom setups already, just not with many of the present "kits" as the turbos are designed for quick spool up and sub 500whp numbers. You can make as much power as needed on a single turbo, the only difference is that the turbo sizing is much more critical than a TT setup.

I think this stigma is going to be changing very soon, however.

 

With the twin turbo offerings we have, I doubt that very much. Can 500+ be done on a single? Definitely. That said, I doubt very much we will see more than a handful of legitimate 500+ singles

 

What does that have anything? (consider that a rhetorical question) I know of no less than 5 people on these forums that are going to be doing a high hp ST build as soon as the option becomes available.

Anyway, I don't want to argue here. Im just saying that there will be more opitons in the near future.

 

I vote for APS, cuz its the meanest exhaust Cant wait to see the powerband on these high hp singles...

 

APS 3" has my vote, lovely build quality, and noise to boot.

 

maybe.. injen SES manages to get up to 450 on a APS twin..... so with cams youll get to 500s

that is BS, supras can easily(but not cheaply) get over 600whp with their turbos and runnign single exhausts....

the current limitation of 500 whp on teh Z is not related to the exhaust but in the turbo kits(piping, wastegate etc) set up i'm sure.that will change with stage2 on the tn kit for example.....some other custom single turbos out there have ran in the 550 range already on the z

 

Thats me...508hp on a Vortech T-Trim. I'm running a custom true dual 3in. with Apexi 3in N-1 Turbo Mufflers and two Magnaflow Resonators, no cats.

 

Ummmm.........OK????

Compare the V6 in the Z to the inline 6 of the supra and tell me our singles are comparble??????

I said it can be done, but the vast majority will be using twin setups on the Z to run bigger power (500+)

 

your comment was related to the single exhaust... which is what this thread is all about... there are way way lots of thread about the turbos and all, and basically current single kits are not designed to be pushed for over 500whp so thats the end of argument...most going for more do twins cause that is what is currently prooven for that power, TN stage 2 will be desined for high whp on a single so it will start to be a lil more comom to see singles over 500s way more often now... you know this already

 

Well...........after rereading everything I read correctly the first time, I am pretty confident that we were all talking about about dual exhausts and twin turbos in relation to the OP question.

 

Risking to face the wrath of taurran, I will still be a troll and try to give a bit of my own input on this.
Supra is a horrible example in here. Ideal exhaust is a straight through with minimal bends (for turbos at least, they seem to like zero backpressure). Our cars have vees (no ****). So far most of 500+whp VQ's were running TT setups (don't know how will it be in future, so TN camp, stuff it). So, dual banks, dual turbos, dual exhausts.
Supras are completey different. Single bank, single turbo, single pipe. Ideal 500whp ST Z exhaust would be a sinlgle huge pipe as well.
The thing that I want to point out to quicksilver, is that the modifications are not purely function driven.
The "traditional" Supra rear end incorporates a huge titanium tipped canister cocked to the side, while Z/G's are "expected" to have dual tips.Another good example, the TD system for the 2004 GTO includes 2 pipes that exit at same point next to each other, so it may look like a signle. The ## of exhaust tips does not mean anything about what's underneath the car.
At least I think so...

 

APS 3" sounds great man! and it will support your power too..its really nice and rasby, sounds great when u get on it. Especially if half way through your rpm range you here your tubros spool and kick in..On a built motor..insane..

 

 

Your original statement had a little different meaning behind it than this. I can agree with you here.

But, whether its a I or V motor doesn't mean that a single large turbo can't be effective in both cases. As Quicksilver said, its not the turbo configuration that's the limiting factor here, its the components of the kits that are currently on the market.

Not bothering responding to Oleg here, he basically took a paragraph to explain what you put in one sentence...

 

The wrath of taurran is unavoidable.
If you read the full "paragraph", you'd see that what I was driving at, is that when it comes to exhausts, the form is NOT set by function, at least not purely.
P.S. You ARE bothering to respond. It's rather amusing, you seem to be so bothered by my posts, yet you can't put me on your ignore list. But I understand, I love you too, my cantankerous darling...

 

blah blah blah blah


jic can, hks can, greddy can... fighting...

comment on this can

 

Thats for when he said 500 whp + but how much plus 275" is for sure a good choice for 500 whp + meaning 510" and u will b squeesing it realy hard....
3" now thats what u call a well done job, cause his intentions is 600 whp as he mentioned later on and its not poss. without 3"....

 

man thats for sure a big NOOOOO u wont b able to boost any way to reach that # with 2.75"..... 3" once and for all...
