Twin-Turbo 71 Chevelle

alex · **Posted:** Mon Oct 27, 2008 9:44 am

I own my Chevelle for over 10 years. At that time I just passed my driving licence and bougth a 350SS 1971 Chevelle. The car looked cool with a very big engine for France

I then rebuilt everything and made several engine modifications including natuarly aspirated, draw through carb , blow through carb and now Tec injected.
This summer I had many problems with the TEC, it was absolutely impossible to make any positive adjustment (Fred had a look at it and it should be perfect now). Despite this my best ET is 11.30 @130mph with a real street car 3900lbs full steel body.

Engine is a 355ci Dart block
Vic Jr heads with inconel valves 2.08" / 1.6"
2 garrett GT35R turbos with huge A/R
Bell intercooler
96lbs MSD 4/1 injectors
Mecanical roller cam with 0.620" valve lift 255°-262°@0.050", LCA 114°
9.5 CR
Boost 22PSI
Water Methanol direct port injection
Fuel is our European 98
For 2009 I will turn on the Full sequential injector mode to have a better idle quality

A friend of mine is running exactly the same configuration on a V6 Typhoon engine dynoed at 1000+hp

A video of my first run with the TEC3
Track is at 1000ft, very slippy with 60 ft in the 2.1s with 28" slicks. That's my 11.30s run @ 130mph with 1 passenger.

Here is the dyno video. Around 900 corrected DIN HP (800 non corrected, temperature was like a Sauna in the dyno)
Thanks to water injection I had no knock. The session lasted for 3 hours !!
