TVS2300 Boost question LS2, TVS 2300, TFS 235 heads, 222/230 .597/.600 115+2
i originally thought that my pulleys would work out fine. 3 inch front, IW 8 inch OD crank and 3.0 and 3.490 OD rears. This ratio is 16% overdriven. This spits out 17-18 psi....too much. Flipping the rears is 86% under driven and gets me 7-8psi...too little. So I am calculating to have 12-14 psi with a 1-1 rear set up, if its linear.....makes sense right??
I don't want to mess with the other pulleys at this time so hope my thinking is right.
I would like to use the 3.49 pulleys for the 1-1 rears. Will that work? Should I just order from Magnuson? I think I saw on here that someone made a 12 rib rear set up for the rears????
I thought I would share the dyno plot of the super boost run. trying to do a steady state point at 35MPH and rolled into the throttle and the tires blew off the rollers. I was looking at the graph and seen the torque was only 310 ft/lbs at 18 psi….but I plotted the wheel slip and that torque was at 46% wheel slip! That’s over 480 ft/lbs of torque at part throttle.
