Would anyone like to make 450 to 470 hp at the tires with your 996 GT3? If the answer is yes,then you need to ck us out. We have developed a twin turbo kit. Running 5 psi the car is putting down 450 hp.

More pictures and info soon. We also have a kit for 996 and 997 available.

 

Very Interesting to hear about boost on a GT3, I find it almost impossible to have boost on that type of compression...

Thanks for reading our first post. We have been turbocharging cars for a long time and have experience at it. Putting 5 psi or so of boost done properly should not affect the engine. Several things that need considering of course but taken care of should make it work well. Currently we have over 10k miles on our car running 5.5 to 6 psi. The car is just an animal particularly once you get into the cam. It pulls like a freight train all the way to redline. Let me know if you have any other questions.

 

I would likely just go for a 996 gt2

 

Ivan showed me the car at Summit Point. Nice looking setup. Too bad he didn't let me take the car out on track for a test run

 

Ivan sounds interesting but imo that kind of goes against the NA raw purity of the GT3/RS's.
Regardless it's another way to the power.
Sharkwerks has the 3.9L conversion and I believe made 465 rwhp and keeps essence of the GT3 engine & feel.
Regarding the CR issue, it maybe apples & oranges but ESS, Gintani, Active and G-Power have SC'ed the E92 M3 (12:1 CR) and are I guess doing well and making > low 500's to the wheels.

Ivan PM me more info. Good to compare plus have you thought of a built motor to run greater boost?

Cheers

wouldn't it make more sense to just get into a turbo or GT2?

 

Guys,

I've also seen Ivan's turbo 6gt3 at IMA and on the street and the car hauls ***! I was at IMA getting some work done and the amount of knowledge Ivan has is incredible. He blew my mind with some of our conversations haha. Ivan is a great guy and has one hell of a facility!

I've also seen this car and have talked with Ivan a number of times. Good luck Ivan and welcome to the 6.

 

Wont those intercoolers heatsoak in that location.

 

Thanks to all that have posted, particularly those who know me. Thanks for the kind words.

The intercoolers will heatsoak in traffic as well as other cars for sure. The pictures do not show the carbon duct we made for the air to air intercooler. This being my car and having the Cup deck lid with a Crawford wing I opted for the air to air. In the production runs we will use water to air intercoolers as they will work great. Thanks for the observation. BTW once the car gets moving the inlet temps go right down, also the efficiency of the compreesor and the low manifold pressure help to make lss heat than expected. All good things when considered.
Thanks again to all.

 

It certainly is a personal choice on how you get more power behind you. Most of the guys who have shown interest in the kit don't want to spend the money for a NEW turbo or GT2. This would mean buying used and some people aren't into dealing with the unknowns of buying a used high performance car when they already know the history of their own vehicle. In some cases you may or may not get the same factory built handling either.
Some guys just really love turning their car into a project to attain more power....

 

No different than the Subie.. As soon as you get any speed the temps drop right down..

 

I think its an innovative setup as i see it.. I think as you continue on there is much to improve upon the kit.. Some advice maybe to use the New Billet Air cooled lineup to simplify system without water to the turbos.. Also the coupler off the Turbo outlet to be casted as those 90 degree bends over time split there.. maybe not at 5psi but still a good idea for precaution and wont add much cost.. I Like the vband housings for simplicity of maintenance..

I was considering building a 1 off setup myself if I got bored.. Glad you took the plunge.. I dont see any issues with 12:1 compression.. I have run 49psi of boost at 12:1 with no issues.. The tune must be in check and fueling.. While the GT3 Motor is stout, on Boost be careful with the Ti Rods as they are normally HP Specific in design, and weight..

What are you using for engine MGMT?? Thanks!!

I have some feedback for those that question the loss of the NA type of personality with such a setup.

I had a 96 993tt running 20 PSI of boost. While fast as hell (approx 600hp) it did have that lazy personality off boost and delays (lag) in power delivery. On the street banging gears was not a problem. On the track it was a handful.

My new project is a 993NA VRAM with turbo conversion. It has 10.7CR and runs 6 PSI of boost. The car retains all of the good personality traits of the NA motor (throttle response etc) yet pulls like a freight train. The torque curve is very flat (will post dyno later) unlike the turbo motor. Because the boost is so low and compression high (heat) the turbos light up right away. Everybody that has ever driven the car describes it the same way. It feels like an NA car on steroids.

Don't discount this approach. Just look at the direction Porsche is going with the new Turbo. They have upped the CR and lowered the boost on the 2010 models. Done properly a turbo charged GT3 will retain all of the good personality traits and give you much higher power output.
