    Double DIN display

    No replies… Come on guys I don’t know who did these installs but they did a good job. Is just trimming the console cover enough to fit in the Double DIN display?

    Double DIN display

    I remember seeing here couple of people installing Double DIN head units on their SRT-10 console. How is it done? What do I need to modify to fit a Double DIN display in my SRT-10 console? Do you just trim the console cover to fit the Double DIN in? Is there room underneath the console cover...

    Tire sensors vs. no tire sensors

    Hmmm Hmmm... If you can’t tell the difference between a flat tire and a normal tire, you definitely need a low tire pressure sensor. You probably need other sensors too. A sensor that will go on when it starts raining and tell you to pull over and put the top on, linked to a barometer and 4...

    Tire sensors vs. no tire sensors

    Yes, you will get a chime on start up and the low tire pressure light will be on. All you need to do is take the low tire light bulb off. :D :D Just kidding. Leave it alone. It doesn’t bother that much.

    HEFFNER PERFORMANCE

    Exactly. As long as you have a well engineered package, the exhaust diameter and small bends in the exhaust won’t be the limiting factor. Real life data here. 8.75 in the 1/4 mile with a street car using 3" Mopar catback exhaust. :headbang: :headbang: :headbang: How much CFM does the...

    Looking for Stainless Steel Side Sill plates for my SRT-10. Who has them? How much? Thanks.

    HEFFNER PERFORMANCE

    As long as the exhaust piping is not restrictive, 0.2 psi back pressure in the exhaust on a Twin Turbo SRT-10 would not do any considerable difference. As long as you have nice, good flowing headers and up-pipes that flow the exhaust gas from the engine to the turbos’ exhaust housings...

    HEFFNER PERFORMANCE

    My car is making 1200 RWHP and that equates to 1,412 HP at the crank if you consider 15% drivetrain loss. I have 4 inch side exit exhaust with mufflers and it works perfect. Not everybody will need 4 inch exhaust though. I’m not sure if Alex is getting the Stage 1, 2 or 3 Twin Turbo kit...

    Well done Robbie. When are you going to Twin Turbo your own SRT? You know you want it. :D

    HEFFNER PERFORMANCE

    Jason Heffner will give you the best answer but let me try to answer it in short in my way. A well engineered and good sized twin turbo system will outperform a supercharger system in every category. No belts to maintain and hassle with, monstrous torque available in the lower rpms (my Viper...

    Thanks for the compliments on the car. The plan has not changed. Make no mistake. This Beast will soon start owning the autobahns and kicking some European a*s. :headbang: :headbang:

    HEFFNER PERFORMANCE

    <font color="red">HEFFNER PERFORMANCE</font> I went down to Sarasota last weekend to test drive my 2005 Heffner Twin Turbo Stage 3 SRT-10 and I couldn’t be happier with the car. Everybody can put twin turbos on a viper and call it a day but what Heffner did is a complete...

    COMP COUPE RACING EXHAUST?

    You asked how the Comp Coupe exhaust sounded. You ask and you shall receive. Here is the show stopper Comp Coupe video. :headbang: :headbang: :headbang: Now you know how it sounds at idle...

    COMP COUPE RACING EXHAUST?

    The best mufflers that will give you the most HP are called..........TURBO. Isn’t that right? I wouldn’t go straight pipes on a SRT-10. I used to have a supercharged Z06 with straight pipes and that’s when I lost 90% of my hearing. There is not much HP to be gained from the exhaust in...

    Michelin PS2 Tires in 18 inch Viper Sizes!!!!!!

    Ask Jon B about the Sport Cups and see what he says. If I remember right, they were his second favorite after the Kumhos. Yes the Sport Cups want some heat in them but they have better traction than the PS2’s or Pirelli’s. PS2’s are not bad either. [******] puts them on his 1000 HP TT SRT-C...

    Michelin PS2 Tires in 18 inch Viper Sizes!!!!!!

    We had dozens of threads on tire options for the SRT-10 and everybody has some ideas. I’d go with the 345/30 – 18 Sport Cups any day over the PS2’s. My $0.02 http://michelinman.com/overview/pilot_sport_cup/1719.html If you are going to change the rears to 335/30 – 18, I think the Kumho V700...
