Dyno Result for Hotshot Performance Probe Header

By: Chuck Cawthorn I dyno'd 8 runs., 4 with the stock manifolds on. I then removed the stock logs and put the Hotshots back on and ran 4 pulls with the Hotshot headers. I am very pleased with the results. Stock manifolds: 157.9hp/151.8trq Hotshot headers: 171.6hp/159.3trq That's a max gain of 13.7hp and 7.5trq. But even more impressive is the gains from 5,800-6,200rpm! 28hp! Almost 30hp! With the Hotshot headers, the horsepower curve started to increase at about 4,800rpms and continued to gain up until the VRIS butterflies close at 6,250 or so... per the klde specs. Tying open the VRIS secondaries should yield another 8-10whp. I have a custom burned EPROM that will do this and I am going to dyno it after I install it.   Chuck Cawthorn Hotshot equipped Probe
