Okay so the proof is in the numbers. Video's and Pics Provided... 2004 New Beetle Convertible 1.8T 6 Speed Manual Transmission Swap (Trans is from a 2004 GLI) (stock 02m clutch) ATP Hi- Flow Exhaust Mani ATP Eliminator 2 Kit w GT3071-WG ATP 3 Inch Inlet for Eliminator Kit HKS Manual Boost Controller TurboXS Blow Off / Diverter Valve ABD Front Mounted Intercooler ABD Intake Manifold Eurodyne 630cc Mafless/Emissions Delete/Cat Delete Tune Seimens 630 CC Injectors 2.5" Techtonics Tuning Turboback w/Hi-Flow Cat & Borla Muffler Dynos without Water And Meth: First Pull yeilded 310WHP See here: Video Here: http://www.youtube.com/watch?v=sMYhB3jWiVw 2 Pulls later heat soaked the Eliminator kit did 294 WHP. EVERYTHING BELOW IS USING WATER & METH So we had run the car 4 times it was time to just add water and methonal to the mix to see what would happen! This brought us up to 313WHP just after the car was at 294 without adding water and meth.. See the video here: http://www.youtube.com/watch?v=aBOClLqmPPM Okay now lets bump this mutha's timing up and see where it gets us... 345 WHP! YEP.. 345WHP http://****************.com/smile/emthup.gif http://www.youtube.com/watch?v=_9OUlRkaI6Q So there ya have it!!!! I did say that this car was around 340-350 and I was correct! The Water and Meth allowed us to really push this thing and we gained some serious HP on this kit from the heat soaked run of 294WHP to 345 WHP!!! THATS 51 WHP AS A RESULT OF THE WAI!!!!!!!
Pros: serious HP gain
Cons: heat soaked

Volkswagen New Beetle
