What kind of engine configuration would you like to see for initial testing?

 

Stock, then cam only...something with mild numbers and 114-115 lobe centerline.

 

I think most people will want to see one of two things.

1. ls6/ls1 with just fuel upgrades and mild safe boost.

2. ~9.0 compression, high flow heads, turbo cam, forged pistons, max boost

If you could only do one, then #2 would be more useful for showing the potential.

 

forged internals with lower compression

there cant be too much difference between kits when u can only run like 7psi

i wanna see something that can make big power

 

Show us what she'll do. In theory you should be limited to what the turbo and down pipe will support, let's see a max effort. We already know the kit will out perform a stock engine.

Again, I'm really excited about this kit for the money. All these guys jumping on the STS kit are going to miss the boat on a better design for less money.

 

Exactly. I think advertising some huge rwhp #'s would be your best bet for marketing. Granted, advertising some good #'s on a stock car would be good as well. But I'm in the market for something for my 408ci. (if I can ever work out the little bugs ) Forged, big #'s!!!

 

Stock LS1 for my vote.

 

I really fail to see the point in this. I'm not knocking you, but just about ANY of the turbo kits on the market, or coming to the market, will make enough power to destroy a stock short block. Not to mention a pound or two of boost can make a big difference in power output and there is not guarantee that each kit manufacture is running the exact same psi (or even reporting honest info), so comparing results from one to the other is somewhat futile IMO.

A max effort will at least show you what the system is capable of.

 

 

my vote is stock z06 because thats what i have.

but i have a LS2 bare block sitting in the garage that will become a forged 9:1 402ci, bolt on the 6.0L stage 3 LPE heads and instal the turbo cam that i have sitting next to the block.

id drive my car to KY and leave it for R&D in exchange for a kit j/k

 

Guys,

While a lot of people may first opt to show the results on a stock application, a max effort setup will show the upper end of what a system is capable of. It will help to determine the upper boundaries due to backpressure, exhaust sizing, turbo sizing, etc.). Most won't hit those upper limits, but more than a few people will. Remember, an inefficient setup will shine most on a stock application where airflow requirements are lower than a good cam, good heads, etc. application.

 

In all honesty I don't see why this is such a debacal. Those of us who are smart enough to know the compressor map of a T-76 (~950 crank HP) will know the upper limits of this system on a forged motor.

However, getting a stock engine to perform, at boost, without blowing up is another challenge. FYI, I've seen 5-8psi on a stock motor and 10-13 psi on an Intercooled motor. More or less depending on weather and fuel.

Most people aren't going to buy a turbo kit then turn around and buy a forged motor on top of it. Most will want to use their existing motor, try it, use it, have fun with it...then maybe move up to another motor in a few years.

 

Just a fyi, the T-76 GTS is rated @ 1100 FWHP

 

I agree. With enuff $$$ you can produce 1000 hp out of a freakin Toyota Camry. So to demonstrate what a high dollar, bullet-proof, big-boost monster turbo system can produce is great for bragging rights...but it's not what 90% of the owners want.

Most want a relatively easy, straight up bolt on (little or no fabrication/modification) system that is:
-Reliable
-Safe
-Inexpensive
-making decent power (550 rwhp)
-capable of being driven on a regular basis

Only a select few "hard core" enthusiasts want/need/can afford 900+ rwhp. Unfortunately I only have 2 out of 3 of those characteristics (guess which one I'm missing ).

 

 

I think some of you are missing my point. We all know what a T76 can do...thats not what is in question. It is the other supporting hardware. You want to make sure that the entire system design is efficient enough to flow well. A bullet proof motor doesn't equal an efficient one. For example...I'm running decent heads and lowered compression motor...not a high dollar max effort deal. To get my system to the point that it is now, I had to change inlet routing, ic, and a few other things. If an efficient system flows well on a max effort setup, it will definitely flow well on a stock motor.

Along the way I wanted to step up to a 427ci motor...even had one built. I learned that my setup wasn't ideal for that type of motor. Needed larger downpipe, T6 turbine, etc. to run efficienty. Now my setup kicks *** on a stock/close-to-stock cube motor, but isn't ideal for a big inch motor. Would you know that by bolting my setup to a stock motor...probably not. That is because you would never test the flow limits/efficiency of the system.


Btw, any power adder can flow well enough to blow up a high compression stock motor. The tuning, for the most part, will dictate longevity. Everyone is searching for the holy grail...700rwhp, 91 octane, stock motor power adder (non-nos)...oh yeah, it cant cost more than $5K. For the newbies, do a search. For the old-heads you should know better....that system doesn't exist.

 

FYI, the title states T-76. If it's a T-76 GTS then that is my mistake for not knowing he was insinuating a GTS style turbo.

Earl H. is correct. While some achieve good results with a home-built system, an "inexpensive system" only co-habitats with more parts and you end up spending more than you initially thought.

 

ok, i know its a precision turbo and as far as i know they only have a GTS

As far as I know they make more than 1 style of wheel. If you look a little further they also make a GTQ style wheel. Being open-minded is key:

I was just trying to help. Just to clarify, the turbo will be a PT-76 GTS.
