just wondering if anyone had done any before and after dyno testing on a turbo setup with any or all of the bolt ons (spacer, mrev, tp's, y-pipe, and I believe some people do headers on TN setups). Would be interested to see how bolt ons effect the curves of FI'd cars

 

bump... lots of looks but no replies. I know someone has done this

 

you won't have the same extended rpm band as you did NA.

due to the pulled timing on a boosted car on pump gas, you'll lose some top end.

 

Well I know in your case header-to-turbo exhaust replacement with heat-wrapping would help the spool incredibly. Have you read about that???

Go search for the STS heat-wrapped exhaust, you might be surprised. Of course it's not on a 350Z b/c nobody has been incredibly expiramental with the kit yet since it's brand new, but it's been around a while on the Crap-maro's and Corvettes. See what they say helps out that kit.

 

i went to the camaro forums and got NOTHING nobody on that site has this kit apparently. I think I'm gonna do the heat wrapping though

 

i wish someone else would try it first though just so i could see

 

There are some dyno charts floating around here of ST kits with various mods. I think Z PHAT Z has before and after with Stillen headers (he gained power by going back to stock) and then before and after with Borla exhaust (showed big gains on the bottom end). Search for that screen name and you should find them..

 

gracias mi amigo de escondido

 

De nada mi amigo de Concord...

 

I think I have a few dyno's charts around. I have a stock dyno, then another one with just an injen exhaust, and then two more dyno's at a few different tunes after the ST went in.

 

would be much appreciated

 

Dyno charts (stock and with just the injen exhaust):






After my first tune with the APS ST... I don't think I ever scanned the last one they gave me.

 

It is really hard to compare them to us since we have a Rear-Mount Turbo. We don't know it yet if Rear-Mount Turbo like back pressure. I had some email exchange with Rick (STS Owner) regarding heat-wrap and he said it help a little but never said that it's a must for better performance. I think TegraRacer134 will be swapping Test Pipes/Y Pipe very soon so that will also give us an Idea. I guess the 5 of us (Sub zero, TegraRacer134, goosegoose me and you) will just have to share some info regarding changes we made coz there's not much out there yet

I'll be upgrading to a bigger FMIC (thanks to GurgenPB) and I'll let you know if that help but it might not apply to you since you have your charge pipe exposed on the side for better cooling. Mine is right next to the exhaust and that is why my IAT has gone up.

 

yeah i'll probably be doing test pipes soon as well. hoping that will decrease the spool time

 

i have high flow cats installed and felt a LITTLE difference...My car is down at the moment because i had to get a new clutch because my fidanza wet out
I am getting a JWT clutch and flywheel combo installed ^_^

 

I am debating whether i should sell my car and start a new project or build the motor....but i think a great bolt on would be cams for your new FI set-up

 

build the motor. I'm eventually probably going this route and would like to see someone else try it.

 

 

can't see the picture

 

Yeah, gotta figure it out why it won't display
