We finished up a prototype ramhorn manifold a few months ago on a customer car and never got a chance to play around with it on the dyno. Yesterday we wanted to see a before and after with the Labonte meth kit that we just installed. The car was strapped down to the dyno for a few pulls. What was supposed to be just a couple of hits to get the meth set up turned into some serious numbers being produced!
Specs on the car are as follows,
2007 GTI 6spd
93 octane pump gas
Stock motor with just IE drop in rods
Unitronic BT software (RS4 injectors)
Autotech HPFP
FFE fmic with Precision 750 core
FFE v-band tubular bottom mount ramhorn, Tial MVS 38mm
HTA 35r with Tial .63 housing
Labonte water-meth kit using standard M7 nozzle.
WITHOUT meth, on straight pump gas at 26psi the car made 433whp
With the meth kit installed, 26psi yielded a cool 466whp with 0 timing pull, working with Mike Z sending logs back and forth some file tweaks were made for the final number of 550whp/454tq at 34-35psi.
We're in the process of developing a full fuel system for the MK5's as well as a cheaper alternative of an additional fuel injector with programmable controller that mounts in the intercooler piping.
Some pics of the setup and a video of the dyno pull will be up shortly, enjoy everyone. If any questions, just ask http://****************.com/smile/emthup.gif
