I have 2007 GT500 that has about 100,000 miles on it, but still has good compression. The only mods I’ve made to it over the years have been to the suspension, brakes, and differential, but I’m now planning to add a supercharger and my choice is between a VMP 2R vs. a VMP 3R, with a price differential of about $1500 for the head unit alone. The choice is time-sensitive as finding a new VMP 2R is getting harder every day.
My goals for the car are 700-750 RWHP on 93 octane with a 6500 rpm rev limit. The car will never see the dragstrip, but will be taken to the occasional autocross and HPDE.
Common to either purchase will be the following supporting mods: a 2008 harmonic balancer, Shelby Extreme Heat Exchanger, a Ford Super Cobra Jet throttle body, Ford FRPP 123 mm cold air intake, VMP dual fuel pump voltage booster, DW 95# 1000CC injectors, and NGK 3690 spark plugs.
At some point, I may decide to build a 5.8 shortblock, refurbish the heads, and add headers, but those mods are several years off (assuming I don’t break anything in the meantime).
My question is, can I reach my power goals with a VMP 2R and the above mods? Or do I need to upgrade to the 3R? And are there any other advantages of a 3R over a 2R, given my planned usage? And perhaps one other potential concern: my car has a GT500KR hood (with the additional air management ducting for the hood scoop underneath), does anyone know whether the larger size of the 3R over the 2R creates any clearance problems?
