It puts down....Evo and STI walking power...

Only did a dyno run 1 time and that was back on 7lbs of boost. Now, I use the Butt Dyno. Don't care what the #'s are as long as I win.

jrodTc

LOL, I hear ya. the butt dyno is ALL that really counts and the fact that ur whippin up on dem evo/sti boys! I'd still LOVe to see what the zpi kit puts out around 9psi. I'm guessing upwards of 290.

rhythmnsmoke

Mike (Whocares is the SN if you want to do a search) put down 295whp and 300(something)tq at 10.5 PSI.

There is also another vid if you do a search for "dyltone", which was a LONG time ago vid, he was putting down 290ish and 330wtq at 10.5 PSI. Different cars, different dynos, but it gives you a general idea of what to expect.

I understand what you're saying and I respect what you're saying. I really have no need to BS.
dyno dynamics 8.2psi = 252.3whp for me. I'll have to do a dynojet run with the way the car is setup now just to see the difference in numbers.

rhythmnsmoke

^^Please do.

What other supporting mods do you have to go with the turbo?

tCrew_R

everything listed in the profile.

Well guess what, It did because I saw it, 2x. And not picking a fight here, but every ZPI kit i've come in contact with has had numerious problems, that quality if far from Greddy. Don't get me wrong, I like they guys at ZPI and I will go out there again for another shootout, but the product is not well engineered compared to Greddy or Turbonetics. <--- And that isn't just some off the wall opinion either, I seen it.

blown_xa

Every Turbo kit out there is capable of providing more HP than the stock tC motor can handle, just because the Greddy kit is tuned conservativly out of the box doesnt make it crap

blown_xa

Yea I'm thinkin like 284whp

I'm out of this. It could go back and forth all day long. Bottom line is those guys need to get their kits checked out.


BTW, I think rhythm was calling BS on the 280whp on 8psi not 180. Like I said don't recall what psi it was at. Either way I think 280whp on 8 or 10 for a greddy is good.

There seems to be a lot of misinformation pertaining to the GReddy turbo setup:

The GReddy kit uses an internal wastegate. So, for the person that mentioned switching out the spring. There is no spring. It uses an actuator. The best way to control the boost is with a good boost controller.

The GReddy kit come straight out of the box to run @ approximately 5 psi. producing roughly 175+ on the Dyno Dynamic dyno with ZERO calibration.

With the 440cc injectors that comes with the GReddy kit, you will max out the injector duty-cycle at around 8-8.5 psi. At this psi, it will produce 100+ whp (as advertised by GReddy). We have tuned most GReddy kit to produce up to 125-129 whp over stock.

The kit is capable of much more HP if you upgrade the injectors to 550cc or more. The GReddy kit, like most turbo kits on the market for the tC can produce way more power than the stock tC motor can handle.

Our dyno reading in comparison to most Dynojet in our area is about 12-15% lower reading. So @ 250 whp on our dyno is equivalent to 280+whp on the Dynojet.

Most people get too caught up with dyno numbers. They really don't mean much. 1/4 time and trap speed don't lie.


GReddy (GOOD): Tubular style manifold, 18G turbo.
GReddy (BAD): Internal wastegate, 440cc injectors, no pnp harness.

We have installed GReddy tubo kits, Turbonetics turbo kits. We have installed and tuned GReddy & ZPi kits. There are good and bad in all these kits. Again, all these turbo kits can produce more power than your stock tC motor can handle. You will blow your motor before you will utilize all the power from these turbo setup.

If you have further questions, please don't hesitate to call us. We would love to discuss any issues regarding the tC, turbo setup, motor built-out, etc.

Well, maybe the flywheel helped to create the extra #'s. Don't know.

Nice ride by the way.

rhythmnsmoke

Are you serious! Dude, I haven't seen a single Turbonetics or GReddy tC break low 13's in the 1/4 and you want to talk to me about quality! I have no problem racing either of the two...that are SO UBER better than a ZPI kit. Not well engineered IS an opinion. Especially when I mop WRX's, STI's, Evo's and the like with my ZPI kit.

You barking up the wrong tree bro. I don't see GReddy or Tnetics being choose to appear on a televised tuner show while ZPI is dishin out the much needed Scion respect. So much for poor engineering huh?

krdshrk

Out of the box I was spiking 7PSI and settling to 5.5PSI. Dynoed 200 WHP on a Dyno Dynamics right out of the box with the base map. Slight tuning got me to 210.

The 440cc injectors can handle more than 8.5PSI. Gizmo on here is running 10PSI (probably holding at about 9-9.5) with meth injection and they're not peaked.

The lack of a PNP harness can be remedied.

rhythmnsmoke

129 + 130 = 259whp. So, where does one pick up an extra 19whp at an ASTONISHING 8 PSI of boost, all the while...maxing out the injectors...


AMEN to that...Seeing as how I have yet to see a GReddy or Tnetics kit faster than the ZPI ones in the 1/4 mile. Can someone prove me wrong, seeing as how the ZPI ones are sooo.....Not well engineered.

And he says the ZPI kits are poorly engineered.

oh yeah! Well, i can pee farther then you can...HA!

Well to the original poster, I live about 50 miles north if you in Coolidge. I am happy to check out your setup and look it over for any issues. Pm me if you want to bring it up.

Well explain to me how it's advertised as 8.5psi and I was pushing 8psi for the last 5months with no boost controller? Makes no sense to me. Before this post I've never heard anyone running lower than 8psi on a greddy except autos. I would really like to be informed a little better. Maybe I'll just have to call greddy. Maybe they sent me the special 8psi kit. Really, is there a way that my kit is at 8psi without a boost controller? It wasn't spiking either, it would be steady at 8psi.

As for the duty cycle of the injectors I'll agree that bigger could be used. I was at 90% duty cycle.

We post general information from our experience with the GReddy turbo kit for the tC. There are so many factors involved in the different psi reading, dyno number, etc. If you wish to discuss this in more technical terms, we encourage you to give us a call. We would be more than happy to discuss any issues or questions in detail.

The thread started out from a Scion owner who has problems with their kit, but like every other turbo tC threads, it always turn out to be "my turbo kit is better than your turbo kit". We do not want to hijack this thread from this person any further. Please accept our apologies.

So, please contact us if you wish to discuss any of these issues or questions.
