Well we got the modified Boost to run nearly 14 minutes till dry in a Buggy.... initially we were running stock shimming and a JL#4 plug....temps running at 285 degrees and running about 9.5 minutes.... took a shim out of the head and installed a Picco P6TH plug temps 230-240 and 13:48 runtime till dry...with more power and RPM...... can't deny it, Picco's run best on Picco plugs....
even still the Boost has nowhere even remotely close to the performance of the Jammin engines...its a nice smooth driveable engine, but big power speed demon it is not !
