tt vs centri - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

CHRI55 · 08-26-2021, 08:16 AM

So... stuck between going centri and turbo... car is currently na but set up to be more of a centri car (ss4, 4k stall,, 3.91,etc) but talked with a turbo company and said they a nice TT kit will work great with it

Going to eventually build a motor for the car but currently sbe.. looking for 800ish rwhp give or take but still want to be able to just drive it on the weekend, take road trips with it when I want to etc... ik turbos have a lot of growing room but I kinda wanna keep my rear exiting exhaust.. will be a street car but since I changed areas, and it's 3 tracks within 30 minutes, I will be on the track, only Mexico race in my old area.. can I have pros and cons of going either way

Either turbo or centri should allow you to keep your rear exiting exhaust.

I went TT over centri for a few reasons:
-don't see as many turbo V8s compared to supercharged
-I much prefer the sound of turbo vs centri
-easier boost control
-simple install, no crank pinning

I was looking at the ESS superchargers prior to going with the AGP TT kit, if I went centri I'd probably go with ESS.

If you are interested in a used AGP kit + fuel system send me a PM

Don't have either setup but I do know I don't like the sound of a Centri. Turbo to me seems like a more complicated install with all the piping and exhaust what not. Pinning the crank is super simple with the tool. after its pinned and removing and reinstalling the crank pulley not as simple.
Turbo boost can be a funny thing and hard to control depending how you do it. If you electronically control it you will have boost variations as temps increase decrease which can be bad. Manual blowoff valve would be more consistent.
I feel turbos do not last as long with the heat but I could be wrong.

A well designed turbo kit should be bolt on to existing exhaust. IC piping can be a pain to route, but I don't think it's that much more difficult than heat exchangers and circulation pumps - just different.

Same with boost control - just different dealing with a wastegate spring or boost controller vs. pulleys and belts.

If you really have plans to build the motor, Twin Turbo. Gen 5 is easy to work on, and the ceiling for power on a twin kit is just insane.

Early on I looked at top mount and centri. Decided on a Whipple but somehow ended up buying the entry level AGP twin turbo setup. No issues with the turbos or system for 40k miles and 7 years, not even a leaky turbo seal. On a SBE motor but had head work. Yes, power on demand. Centri's have a nice linear power delivery. Turbos, depending on how boost is to be controlled, can enter boost smoothly or intensely. As for the complexity of install, nothing dramatic. With twins you don't have all the "required" supporting mods to make more power (cam, headers, intake). Turbos doesn't need all that jazz, but it does help make power with a little less boost. Maintenance, nothing dramatic. I've watched SC belts get changed too often. Whichever way you decide to go, LS motors love boost and you will enjoy it.

BTW, I don't ever recall a centri beating me at the strip... just saying.

Greenhornet2 · 08-26-2021, 01:20 PM

I forgot to mention. If power goals down the road will be excess of 1k I would go TT.
Another note, I did talk to the Jannetty's about TT last year. Teddy told me about a couple they worked on that made big numbers, but on the street it was not as usable or enjoyable as PD or Centri. The gist I got was it felt like it was either too little power then too much power. Low boost you likely wouldn't have the same issues. At the track you wouldn't have the hooking issues, but on the street linear predictable power curves are hard to beat. It is quite easy to have low boost setup for street and high boost when you take it to the track though with a turbo setup.

RupertPupkin · 08-26-2021, 01:40 PM

If I were to do it all over again, I’d stick with centri. Just the sound of the blower going is nice. Also I would’ve built the block.

I supported 800whp once….then 0 hp. :(

eLeSthree · 08-26-2021, 01:54 PM

Just wanted to say if you decide centri, ESS does not have belt issues.

As far as install goes, centri is waaaay easier. Pinning the crank is cake. Id rather do that than tap the oil pan for the return line, run oil feed/drain lines to each turbo, plus vacuum lines, all under the car. No comparison, unless you have a lift.

Twins are badass though, no argument there.

I was looking at the ess g3x kit and had a guy that was about to pull his and got TT but decided to keep it and sell the kit and at the time didn't want to go turbo.. but I do like the boost control of a turbo but like the easier maintenance of the centri.. but crank pining was something I was worried about

Yea the boost variant of a turbo with heat ir kinda why I didn't want to. I know the weather has a lot to do with that as well as any boost really but turbo most definitely

🤔🤔🤔 what's the price average of a nice tt kit compared to a centri kit

I plan on building the motor eventually.. just want to get the main part out the way so I can build a motor specifically for boost and not na/boost

I really been having my eye on ess g3x not for about a year now... I hear their gearing is different so you don't have to pulley as far down as the others to make the same boost.. been looking at the c6gs with it and been looking at it since. Anyway had a kit from someone here but they decided not to go TT and keep the ess🥺🥺🥺😔😔😔
