Make / Model: VL Colour: Hmmm Dark Red/Maroon, wannabe white Bodykit: Stockish Engine Type: RB30E plus Turbo Engine Mods: 450cc Injectors and rail, 80mm MAF, Intercooler, Turbo, Exhaust, Intake Manifold Power: dunno but it runs 1/4Mile@11.2s WSID crossing the traps at 121MPH Exhaust: Nice free Flow 3'', who said Cat - what Cat? Gearbox: Trimatic 3 Speed with the ole B&M Banger, 2600 Hi-Stall Conv Diff: Stock with new Billet Axles Brakes: Stock, remachined Suspension: Stock but maybe a little lowered (not by choice) Wheels/Tyres: @12.1 we ran 16x45x235, @11.2s we ran slicks and cheese cutters because we had to and added the tailshaft loop. Interior: Stock Stereo: Something that fills the hole in the dash Other Mods: Shhhh top secret Future mods: maybe some pistons as I think one just finally split, another 'stock e-tune' in the factory ECU to push it to 10.90s. Might even remove the spare wheel as it will take two tenths off the ET. Some original photos have not been recovered yet.

We started the day at 17psi and end at 20psi. the turbo is a modded onehunglow with ext waste gate that starts making respectable boost at around 2700 and it's all in by 3000ish when the convertor lets it all loose, thats probably why we've been torturing the slicks in first and second gear and spinning them 1.5 inches on the rim at each 1/4 launch.

Once the mech mods are finished we'll install the changes into a our OEM VL ECU. It's has taken many many many hours of test/tune datalogging the engine to get thus far and the results are almost worth it (as I still like the ease and speed of changing jets). It gets very intense when reprogramming ECU parameters at times to suit the major mech changes to dial in the extra ponies. Look really, if anyone wants to run 8's low 9's it can be done with anything gutted to 2000lBs & 350HP @ flywheel. I believe the Trap Speed is what counts as you need HP to have the MPH. Not just a low weight to power ratio but there aren't many limitations in Nistune that would prevent a good 1/4 time. The aim with this car is always to maintain a real *full street* car that idles at 800rpm, is easy to drive in traffic, has a sleeper street exhaust, run's on pump gas (premium preffered), will launch instantly on command (or if the light turns green) and you can throw some extra rubber under and still have a lot of fun with the extra grip. Though I do love to see a Funny car propel it self from one end to the other in a 5 seconds!!!
