VRP Billet Surge Tanks are one of many of our custom innovations for the M113k platform!
These tanks are proven to add an incredible combination of style and power to any 55K engine. Unlike factory tanks which have bolt shafts running through the tank to the intake manifold, our custom polished billet tanks are completely hollow resulting in improved laminar flow and reduced restriction!
Heres a photo of the inside and the bottom plate, Plate bolts to blower and then the tops bolt to the plate.
We will definitely have Data for these this week, We underestimated the complexity of the Rear coupler, They have been collapsing under vacuum so we have had to source some custom couplers reinforced with steel strips. Right now we are using a metal elbow between the surges and the intercooler but the production couplers are in route.
Remember these are 100% reversible for use with top mount intercoolers
Even if these don't add power I can definitely appreciate the innovation. Between this, the billet snouts, the tensioner pulley adapter(which I hope will work with a clutched pulley), the SC kit that is supposed to be coming down the line, all good stuff.
No other changes, No dyno tuning, No log tuning, reflash is required for surge tanks just like they are required for injectors, on a test we did in November on a heavily modified car the AFR changed from 11.7 > 13.5 with Surge tanks as the only change. On that car we picked up 40whp at 4900 RPM.
Car Gained 31hp, 10tq.

Wow that's a decent bump in power. Great stuff! Thanks for sharing
