Any differences in reliability between supercharger A and supercharger B?

How much does it cost to forge your motor? What exactly is done during forging anyways?

Forging the engine refers to upgrading the internal components. It requires changing the pistons, rods and in the most power hungry cases, the crank. You can buy these items for as little as $1,200, but since you don't sound all that comfortable with installing your own supercharger, you're most likely not going to be up to the task of adding the required forged components to your engine either. You'll likely have to pay for a previously built short block, which can run you in the $2,000-$3,500 range, depending. The stock set up is said to be good for the 400rwhp range, but I've seen them let go at both lower and higher horsepower levels than that.So, that being said, unless you want to really start sinking money into your set up, it's best you stay with a kit that's going to reflect your capable power levels. The S-Trim Vortech is a nice choice too and Modular powerhouse sells a version of it in one of their Mongoose Kits and should put you in the 350-380rwhp range, depending on other supporting parts in your combination. The Kenne Bells are a nice choice as well and will make a little more grunt down low than the Vortech will, but, at a fairly substantial difference in price. There will of course be the argument from Twin Screw supporters to the effect that "if you want the best, you've got to pay for it" to justify the price difference. Which I'm assuming is in direct relation to performance in this sense, since one kit is as reliable as the other. But with that same logic in mind both blowers are equally and easily upgradeable and when push comes to shove, the S-trim will support about 100-more horsepower than the 1.7L Kenne Bell. Another option you might consider, would be an Allen Engine Development Kit, similar to mine. They’re a very well engineered kit and cheaper to buy than the Saleen and the Kenne Bell, but will provide just as much low end grunt and fun as either. They’re also intercooled and utilize the stone reliable, time tested Eaton supercharger. They are admittedly limited in performance though and won’t provide the top end rush of either the KB or the Vortech, but they’ll make as much as your stock engine will handle, which unless you do plan on dropping the money into forged internals is all you really want anyway. The choice is yours; just make sure you make it based on hitting realistic power levels with a realistic budget. And for the Record, the Paxtons are as tough and reliable as the Vortechs as well. As a matter of fact, a lot of people don’t realize it, but Paxton Automotive has been owned by Vortech for the last few years now.BTW…thanks for the Administrator props, but I don’t think it’ll every see the light of day. They’d never give that kind of power to a Canadian.
