That is a great setup! Looks like a ton of work, but it came out great!:yup:

how much does it cost?

[sikhabib]

whats the ground clearance like on the Turbos? Could those hoses that go under the gearbox get ripped out easily?


Looks good by the way

[peter@aps]

whats the ground clearance like on the Turbos?

There's loads of ground clearance, you'll tear the steering rack out of the car before the turbos will ever become a problem. You don't see any steering racks damaged by insufficient clearance so there's the answer my friend.:)

Thanks for those kind words and the hoses are well protected by a steel sheild, over 60,000 miloes of road testing so far and never an issue with the hoses, all good. :yup:

Well, I think it looks better than many of the C5 TT setups I've seen. With the precipitous drop in price on used GTOs (I've seen 20s)...I may pick one up for a complete set of highspeed modifications, beginning with these TTs.

Great job and thanks for sharing!

Gee, That's an amazing price for a used GTO and awesome value if you can indeed find a well looked after GTO in the mid 20s, good luck with your hunt and I hope you find a pre loved GTO to your liking. I'll post some new pics on the twin turbo system in the near future, great to know you liked the twin turbo package.:)

I just love these LS6 / LS2 motors and think people poo poo the GTO unfairly. I am on the fence though between the 04's and 05's, as, for example, CarMax reflects about a $4,000 price difference, and I am not convinced it is worth it, rather out the $4,000 to a TT.

Anyway, I did not mean to hi-jack this thread....I look forward to seeing what the future holds for power adder stuff.

If you're going to go with an intercooled twin turbo system you may as well save the $4k and get the 04 model with the LS1 engine, it will be a very fast car. :yup:

AMAZING SETUP. What kind of HP/TQ does this setup put out? Is this on a stock engine or a modded engine with head work and forged bottom end?

[BIG D's SS]

Nice setup. Anything like that for the f-bodys?

AMAZING SETUP. What kind of HP/TQ does this setup put out?

The max Horsepower possible will depend on 3 main issues,

1) The fuel octane you use,

2) The static comp ratio of the engine,

3) Boost pressure strategy you intend using.

On a stock engine (stock comp ratio) on 91 octane fuel I believe you will be limited to approx 500 to 525 WHP though with a lower comp ratio (nice set of forged pistons) and high octane fuel combined with a large fuel supply system up to 750 WHP will be very achievable.:yup:

Peter

Thanks for the PM'd info Peter,

750 WHP would definitely be the goal of such a project for me, as I would certainly lower compression and add forged internals. Of course, the rear end won't stand up to that in stock form, but that's a whole different thread and conversation. Again, thanks for the info.

[peter@aps]

Lat Saturday our head tuning tech spent approx 3 hours time on the 05 model GTO (APS twin turbo system equipped) with new LS2 tuning software and I thrilled to say that the GTO produced just on 522 WHP at 6 PSI boost pressure. :)

The 522 WHP was generated with larger fuel injectors and the stock exhaust system (APS down pipes connected to the stock exhaust at the mid flange connection) on 93 octane fuel, all very easy to achieve.:yup:

Peter

[Ghost Rider]

That is definitely positive. What PSI were those turbos running at?

[peter@aps]

That is definitely positive. What PSI were those turbos running at?

Just over 6 PSI, I will post power, torque and boost graphs later on today.:)

[HASTINGSRJ]

what a nice set up. My only question is, why are you still using the stock exhaust???? Wouldnt you get a few more ponies out of an aftermarket exhaust:think: not that 522 rwhp isnt enough on 6psi:eek:

:dunno: But still, that is a really nice set up. If I was to buy a GTO, I would definatly go with a set up like that.......

[Exotic Performance Plus]

Plenty of horsepower can be achieved with the stock exhaust system, and unless forged pistons and better rods are added, the total rwhp that is achieved has to be kept in check. Once a better bottom end is added, then a better exhaust system, cam and heads can be added. Bob

[HASTINGSRJ]

thanks for the info Bob.....

Thanks, glad you like the APS twin turbo system. No doubt more power would be available with a larger exhaust, as we were out of fuel supply at 522 WHP (this was the first factor to limit power) we did not worry about going to a higher flow exhaust system for now.:)

Peter

[Exotic Performance Plus]

thanks for the info Bob.....

Hopefully it didn't sound like I was butting in, it's just that no additional performance items are needed, as twin turbos are so efficient that they can supply plenty of power to blow up a stock bottom end, if one chose to purposely up the boost that they are capable of making. Can I say all that in one sentence? ... Bob

how come the torque is so low???? is that different then most other dyno-graphs?

[peter@aps]

how come the torque is so low???? is that different then most other dyno-graphs?here's a better graph to demonstrate the huge torque generated by the APS intercooled twin turbo system.

http://www.airpowersystems.com.au/ls1/ls2/530hp_power_t.gif

Stock torque at the tires is 320 lbs ft whereas the APS twin turbo generated just on 520 lbs ft at just under 7 psi turbo pressure, that a huge 62% increase in torque at the tires, all good.:)

Is the stock bottom end limited by horsepower or torque? That is, I saw 520 wheel tq at 4500 rpm, would the stock bottom be able to take that much torque at say, 6000 rpm?

Will the GTO automatic take the horsepower and torque of the pump gas (93 octane) setup at 6 or 7psi?

[peter@aps]

Will the GTO automatic take the horsepower and torque of the pump gas (93 octane) setup at 6 or 7psi? The GTO auto trans is quite robust for low boost turbo applications. I'd certainly recommend that you consider a large trans cooler for any FI on the GTO, cool trans fluid helps the auto clutchs live longer in high torque situations.:)

Peter

[TA Jack]

OK thanks for the info. I know that heat is the main reason most automatics fail. My 04 GTO lease is up in a couple months and I am going to replace it with an 05 or 06 and I love the turbo in my 96 Impala SS. Could you PM me pricing info please? And are you looking for any stateside dealers? Unlike down there, spring is right around the corner up here. :-)

Hi all, I have one of these Aps Twin turbo kits on my Hsv ls1 in australia. The car is making 531rwhp and im in love with the power, The ride is awesome. Its very driveable around town.

Please let me know you thoughts on this.:)I've never had a problem with the stock composite intake manifold on an LS1/LS2 engine (that said I would say it's not impossible not to have a problem given extreme levels of boost) and that I feel is because the inlet air temps are very low due to efficient air to air intercooling on the APS twin turbo system, hope that helps. :)

Peter I am in the process of completing a 455HO superstroked ls2 in my 05 gto. HP,Tq is 605hp,610tq at the flywheel. I Want 1,000hp and 1,000tq to the rear wheels. But i dont want to use anything but 93 octane. Do you see this feasible with your tt setup. I can imagen if i use 104 octane i can hit my goal but if i use anything besides 93 octane it would be all out at vp import 121 octane fuel. That fuel costs waaaaaaaay too much and i am aiming at touring the country so pump gas is manditory. Any help is much appreciated.

Thanks.... 7.5L

Ps. The setup is pretty much the same as the 455HO kit built by MTI, if your familure with it.

Well I appreciate your feedback Peter. I guess I should have worded it better when I said turbo spec??? Anyways In your opinion what do I need to do to make this system support my goals.

I'm not sure that I can help you with your power/torque goals. Right now we have no plans for the GTO TT system to generate 1000 rwhp/rwtq (around 800/800 is very doable) as there's no affordable drivetrain that can support that massive torque level. If this changes into the future then who knows, maybe APS will look at building bigger twin turbo packages. :) :dunno: :cheers:

Peter,

How are you today?

Got a good one for you, i have a 2006 Holden Statesman, Chevy Caprice SS. I have emailed the guys in APS Austrailia and well no kit exists. Another company has one that will squeeze in but i have to relocate the batt...Let the record show, i am not going for the other kit for i like the stealth look.

Also i have a M12 transmission (t-56 manual) and the max rated Torque is 400ftlb. if your kits puts out 520-530 ftlb wouldnt that slaughter the transmission?

I'm really well and hope you are also. The GTO intercooled twin turbo system may well fit the Holden Caprice with some modification to the intercooler tubing/plumbing, only one way to find out for sure.
