Sean tuned me over at 1320 also. Nothing but good things to say about Sean and the 1320 crew.

 

yeah, im curious where the posts are stating that cossie's are superior to gsc.

ill cover the labor and dyno time to test back to back.

I'll take you up on that offer! What do you say? We can do it as soon as you can get me a set of GSC S1's and I will order the Cossies! Let's do it!

 

Why I think my exhaust is holding me back

When I was getting my car tuned a friend of mine was there also with an 8

His mods

Downpipe
Fujitsubo catback
Gt spec manifold
Ebay 02 housing
Tme turbo
Greddy piping
Turbo xs fmic
Some hks ebc set at 32 psi
Spraying meth

His # 360 whp 402 tq

Do you guys think his whp is a little low??
He think it is comparing to some he know who has almost has the same mods make 416 tq not sure of whp ?

 

I was thinking of puttin my greddy ti back on a switching my intake to the hks sean really like the hks one that the only reason and then go to retune it thinking but also I love my quiet exhaust but very curious of changes it would ???

 

Nice # man yeah sean told me you want the most power swap to ams tbe and the hks intake you will see the difference I mean I'm pretty sure ill get up to 360 whp or close and make some more tq but I know how ams tbe are loud I spoke to ams already asking them about the exhaust they said it louder then the greddy ti running ams catless and your # are pretty much where they should be

 

Yeah I've just become totally confused by the Cams, I mean we've seen so many IXs with basic bolt ons make anywhere from 320whp to 360whp on 93 octane pump gas. It just confuses me that even with Cams I still see IXs making 320whp to 360whp. Just not seeing a huge difference. But I guess somebody can't really complain about a good 10-15whp gain across the powerband. I guess it is just like what a lot of people have already said, we need to lower our expectations, I've already lowered mine.

 

this would be a great test on a full bolt on / stock ecu car...

 

And it just so happens that I have a full bolt on / stock ecu car!

Let's Git-R-Done!

 

Do it, I would love to see the results with just the exhaust. but personally I dont think you will make an average of 5 WHP if that.

 

ok,

we are going to test them on faust's car...

I am willing to redo the entire test swapping the HKS and exhaust back to back
I will have to work out the particulars, but I am doing it for your enjoyment as I know exactly what is going to happen after tuning 2 360 hp ones only days before, and quite a few prior to those.

StiGuy made this

06 Tarmac Black IX
370whp 386wtq no meth

With this mod list:

AMS Turboback / AMS mini battery / AMS upper i/c pipe w/ tial / AMS lower i/c pipe / HKS RS Intake / HKS 272 exhaust cam / Walbro fuel pump/ Greddy Profec B type-s / Greddy TT / Tanabe GF210 / Exedy Hyper Twin / AMS 740cc injectors /

Perhaps one of the highest HP evo9 on stock turbo/pump I have done.

Edit: nvm...

 

subscribed...do the test!
