congrats! and AAM makes some very good products. thats actually where i went for my tune.

i'm just a little biased to FI exhuast stuff if you couldnt tell :tiphat:

I could. At first doing my research I wasn't sure if the posts were talking about forced induction or fast intentions.. Very confusing. Lol

yeaaaaa that'll happen plus it's worse now that FI makes a turbo kit sooo now you got the FI FI kit or other iterations of the abbreviations

Yeah I saw that too.. FI vs AAM kit. There was a thread about it.


Sent from my iPhone using Tapatalk

yea thats been a bigger debate as of late.

more or less it comes down a. if you have a bias and b. turbo/wastegate choice

the prices are very similar so it makes them competitive. i obviously lean to the FI kit. i like the design and look better plus i've seen a few builds on stock blocks with e85 push over 700whp. very impressive.

theres a stage 3 build in progress a guy here is pushing for 1000whp+ of the FI kit with a 4.0L block.

I'll have to do a lot more research down the line. And not just buy the kit like I did this morning. Lol.. I did read something about the bov being more internal and not letting off the sound for the AAM kit. And that maintenance would be a little harder.. But I was looking for more exhaust information at the time.

yea wit the turbo kit i'd say take some more time before pulling the trigger lol

there's a few differences between the kits that really come down to personal preference and build goals.

Quick question.. Does a new exhaust system require a break in period? I've read up that once they are broken in they get a bit louder.. But I guess my question is should I take it easy for a period of time. Please let me know, thanks!

There is a break in period. The fiber will melt some which does make it louder. Also, the pipes will coat with exhaust soot. That typically helps is there are hints of rasp or tingyness to it.

Thanks SS.. But it doesn't seem like there will be a problem if I push it here and there right?

Nope

Thanks !!

Can I pick your brain a little bit? Will the FI long tube headers fit my current setup? I have the resonated test pipes along with the 3" true duals if you don't remember.

You will lose the Resonated Testpipes. Sorry FP, I knew the answer ;) it's a worthwhile trade-off unless you want to keep the same volume.

Test Pipe vs HFC
 

Are there substantial differences compared between long tube headers vs headers and test pipes or are they negligible? Or is it just preference? Thanks btw for chiming in.

Negligible. Resonated testpipes will be quieter

Thanks SS

i see i'm late to the party lol

LTH may get you a little low end torque vs oem headers/TP

also i'll add the sound will change. LTHs will be a little lower sounder than TPs

i thinks firehawk hit everything else for me lol :tiphat:

would it be terrible if i decided not to put in my CAI.. and upgrade my headers along with my other mods? i still plan on getting it tuned.. but i think im going to go a different route in terms of FI.. and i dont wish to cut parts out of my Z if its going to be moot in the future. any thoughts?

depends. if you plan on going FI soon then i would stop buying any parts. you'll replace any intakes and LTH/TPs.

i hope to go FI within 6 months or so.. my friends are telling me to do more research on a SC kit instead of a TT kit. kinda torn at the moment. do i keep the parts off? not really worried about putting the parts on more so then doing any unnecessary modifications to the car that i cant revert.

SS looking at the sophia project now but is there any thoughts you can add to this? Thanks.

you have bad friends then lol

SC is super limited to what power levels you can reach. then again i dont know your end goals for power.

also intakes and exhaust are easy mods to take back off and whatnot.

Lolz.. perhaps i do.. they made an argument about reliability.. not the most knowledgeable about my car so i turned to the forums to get all the info.. lol

as far as the intakes installation goes.. just dont want to cut the intake air duct if i didnt have to.

TT is reliable at lower boost levels. i've seen some run their cars at 10psi for 30k miles plus with no issues. so it's possible lol

they arent really ducts just holes in the rad support. i just shaved mine down for the intakes to slide through.

Thanks for the info FP! I figure out what i decide in the next couple days and post them up.

just look at phunk build, his daily made 671 whp, he out 60k on that and its still running today. Most ppl bash the crap out of the car when they boost, or have shop do shot install and tune. Choose your shop and tuner wisely.

Ill take a look, thanks Elmo

There are far more members with popped motors from super chargers than turbos.

The highest supercharged Z was i believe SS fireahawk who made 550whp, but that gtm kit had its problems. turbo goes to some guy in texas who made 768whp.Both stock blocks

And SS's car never seemed to make that amount of power anywhere but gtms dyno if I remember right.

gotcha

ill have to weigh the pros and cons i suppose. SS do you like your SC? Do you have an input on it? any thoughts will be appreciated.

Ss sold that car a long time ago. And that kit never ran right and isn't available. Your only sc option is stillen, and that kit has significant drawbacks.

Was trying to get input over TT vs SC.. The SC kit that I'm looking at is stillen and they are local.. But seems like I should get the tuner kit instead of the all in one kit that they offer. Or I read that somewhere I think.


Sent from my iPhone using Tapatalk

There's a LOT of threads on the stillen kit, as well as your available turbo options.

:iagree:

I'll add input when I have some time. I'm busy as all hell today

Much appreciated!

So I've been doing a little looking around and stumbled on the ARK RSpec Res TP.. does the Helmholtz Chamber make a world of different in terms of back pressure? Or again is this is just negligible and left all to preference..

I finally have some time for a proper reply. So to give you a straight answer; for $15,000, it is not worth getting the twin supercharged system. I got it for $10k installed. For that price, it was worth trying. When I first drove it, the thing was an animal. After a month of having it home, it just never made that kind of power anymore. Two tensioner pulleys broke, the stock tensioner pulley broke, belts shredded, and it squealed. I do believe those issues could be fixed, but I was tired of dragging it from place to place trying to get it to run right. I plugged in a basic boost gauge under the hood to see what it was making, somehow it went from 12lbs to only 4. I took it to a shop and asked them to check the BPV's, and they had found they were completely loose, essentially bleeding boost out. After tightening them, it did gain a lot back, but it was in desperate need of a retune. I started getting nervous with all the small issues cropping up, so I cashed her in for $33,000 and started fresh.

So the pros with the kit...
I do believe this kit can easily make 650+whp with 84mm pulleys and a built motor.
It looks seriously awesome under the hood.
The power was very linear and got faster the higher you revved the thing.
It sounded wicked and long tubes fit with the kit.

The bad...
The pulley issue
The squealing
Can still make more power with a turbo
A lot of moving parts
The 3" intakes neck down going through the core support
It was made by GTM and their support was not the best.
