Here are some pictures of the latest iteration of my front mount DIY TT with the 76 GTS turbos:
I decided to upgrade all the systems to the side mounted intercoolers like I originally put on my car almost 2.5 years ago.
Without the front mount intercooler blocking the air going to the radiator, the car runs cool as stock.
You can see the front portion of the front wheel well is the back side of the side mounted intercooler core.
These cores measure about 13.5" wide per side and are 11 inches tall and 4.5" thick.
If you put these together, you would have a 27" wide core that is 11 inches tall.(This is HUGE) Definitely larger than what can be fitted in front of the Gen2 Viper!
Placing the intercoolers here instead of in front of the radiator is a huge benefit when you consider that the front mount intercoolers reduce the velocity of the air going through the radiator by about 90% and reduce the volume of the air going through the radiator by about 75%.
So, in a nutshell this setup allows for a forced induction Viper to have monster aircharge intercooling and air intake capacity while allowing the cooling system to function like stock in terms of how much air can go through the front end of the car and ultimately through the radiator.
==> Monster power/stock driveability!
As you can see, this setup allows the use of some monster air filters that will never restrict the turbos' ability to pull in air!
The air filters look like a pair of fangs!
Here is a clean picture of the vacuum routing of the wastegates and boost controller:
This shows the blow off valves being placed before the intercooler venting the hot compressed air BEFORE it heat soaks the intercooler.
When the throttle plates close, there is also less stress on the turbo with the BOV being so close to the compressor outlet because the air is being released to atmosphere within 5" of the compressor outlet!
Also notice how short and straight the path is to the intercooler from the compressor outlet!
This shows the 4" electric exhaust cutouts that reduce back down to the regular 3" exhaust after the cutout.
This allows you to run super quiet even with catalytic converters at low load just cruising and then you can flip the switch and dump the exhaust within about 3 feet of the turbo outlet.
Dumping the exhaust this quickly instead of having to exit at the rear of the car allows the turbo to spool more quickly and also makes you really hear the jet engine whoosh the moment you breathe on the gas pedal!
Here is a dyno sheet for the previous iteration of my 76 GTS system:
Speaking of more humble beginnings, here is a dyno sheet for my entry level system on a bone stock 1997 GTS with T&D roller rockers and voltage booster for the fuel pump with 55#/hr injectors, fuel rails AEM and my fully upgradeable, front mount TT system:
Please notice it is making 600 RWTQ at a touch over 3,000 RPM. It is making over 700 RWTQ at 3600 RPM and it is still making over 700 RWTQ at 6200 RPM.
This car is so easy and fun to drive on the street.
The power comes on smooth and pulls all the way to the top as you can see!
This is the only Gen 2 DIY TT that is fully upgradeable to 1400+ RWHP whose entry level system starts out with a pair of 700 HP(Each) turbos.
I designed this system so the average owner could start out with 600-650 RWHP and just upgrade the power when they are able!
Just like with anything, you get used to a certain power level and then want a bigger kick in the seat of the pants.
There is no other DIY system out there that uses T-04 turbos that has the upgradeability of this system nor the overall design layout to make big power yet allow the high power cars in hot climates to run cool as stock.
I am starting a run of 10 systems very shortly. Anybody interested should give me a call @ 630-878-3907. There are still a few available for spring delivery!
