First Twin Turbo Gen IV

[JohnnyBravo]

Brought to you by Underground Racing:
"Here are some pictures of our 08 TT Viper. This is the first one known of that is running with a power adder and full control over the cam and drive by wire throttle bodies. I must say that we are very impressed with the 08 platform after it got the TT treatment with the full built stroker engine. Power on pump gas heat soaked is 1000 RW with around 11 psi. 19 psi we made close to 1300 heat soaked. The system also has the Underground Racing/John Reed Motec system onboard! John did a great job on the Motec set up! The TT 08 Viper drives just as it did stock! More information will be released soon."

pretty sweet!

 

[SquadX]

Doesn't surprise me it's an underground car. Impressive as always.
Any 1/4 times or timed acceleration test yet?

 

[SnakeBitten]

Havent seen 1/4 mile/mile numbers yet but he said it is going to the Texas Mile event. Also read that it will run with a Gallardo TT "R" package from an 80 roll if the Viper driver is good. The boost isnt even at max from what I read. Very sick car.

 

[BolsOut]

I WANT.

What kind of Rims are those?

 

[Bobpantax]

Stunning! Is there a site where the parts used and the specs are available? They had to have changed a good part of the engine out. It would be interesting to see exactly what they did.

 

[KNG SNKE]

I just went from 6 to noon!!

 

[Volltage]

Beautiful!

 

[AZMotorgod]

That car is S-I-C!

Yes, a breakdown of the engine, chassis, body, etc... modifications would be nice.

Oooh that this is scary. It is starting to give me the chills. In a good way.

 

[ACRucrazy]

Motec.... sick...

 

[Austin]

REPOST. Still nice to see again though.

 

[FikseGTS]

very nice!

 

[VENUM INJECTION]

0-60 on a stock 08 IS 3.4 If memory serves. Credit where credit is do right? And I am glad someone finally TT'd an 08, I have been waiting to see how that would turn out. Congrats, cool ride.

 

[viperbilliam]

Sick and beautiful in a nasty way.

 

[Shank2117]

What cam are you using? Basically, the engine is almost completely different - right? The VVT and Venom programming are no longer involved - correct?

the VVT & venom controller are still in the car, the motec controls the cam.

 

[Nyoka]

Wow!!!!!!!

 

[Bobpantax]

the VVT & venom controller are still in the car, the motec controls the cam.

With all the changes he listed above that were made to the engine I do not see how the cam within a cam system and the venom programming could have survived for use with the stroker engine and the twin turbos. The SRT Engineers have posted that the Venom programming is very complex and finicky and not friendly to mods. There have been past posts by site sponsor tuners indicating that even just to supercharge the Gen IV would require a cam change and different programming. Also, I thought that the MOTEC was a stand alone controller not a piggy back. Please explain what was done here in more detail. Thanks in advance for your explanation.

 

[SSSSE YA]

Sick and beautiful in a nasty way.

I could not have said it better myself !!!!!!!!!!!

 

[Alexarz]

Why is the car always heat soaked?

Bob,

Vegas is a customer of UGR's. The explanation you want could be given by John Reed (Motec) or Kevin Howeth (UGR), both of which are on the alley, on the identical thread to this one (if you really care). There already seems to be discussion related to the Motec on that thread.

 

[Bobpantax]

Thanks Malu. I will take a look.

 

[Ricketts]

NICE!!!!! Glad to see the 08 code has been cracked.
