Car tuning usually requires a little bit of trial and error. As the saying goes, if something can go wrong, then it probably will, so you had better be willing to go back to the drawing board a couple of times before you get things right.
Complete Street Performance (CSP), a Pennsylvania-based tuning shop that specializes in General Motors LS engines, was recently trying to squeeze even more power out of their shop manager’s 1,300 hp C6 Chevrolet Corvette and saw this lesson play out in real time.
It’s not clear what modifications CSP’s 1,300 hp Corvette has, although it appears to have a turbocharger or centrifugal supercharger, along with a cam and some other standard modifications. One area that the shop looked over, however, was the intake manifold.
Despite having massive amounts of boost on tap, the engine still had the standard plastic intake manifold installed that it came with, which just couldn’t handle all 26 psi of boost and failed spectacularly on the dyno, as you will see in the video embedded above. The manifold failure caused a spectacular and thankfully brief fire, which was quickly put out by some fast acting CSP employees.
While no tuning shop wants to see a car blow up on the dyno, the damage done in this scenario was quite minimal. CSP will need a new (hopefully billet) intake manifold, but apart from that, it doesn’t seem like the ‘Vette sustained too much damage.
The car also produced 1,356 hp just before the intake manifold failed, so it’s certainly powerful. In racing, we’ve been told it’s easier to make a fast car reliable than to make a reliable car fast, so things could certainly be worse for the guys at CSP.
