Ultimate Boost Battle

One of the better videos I have seen in a long time showing comparisons of several different types of superchargers vs. turbos on the same engine, showing the power curves at the same peak boost levels with the same air/fuel ratio and peak timing.

Although it was not a completely perfect test, as there are some minor details that could change the power outputs for each setup, this video does do a good job of comparing them and was a ton of work for him to do, hope you enjoy!

I actually understood the info presented. Now Dave@DDMWorks how would a guy use this info to select one of these options? (Short answer is acceptable)

Flip a coin (shortest answer I could come up with)

On the Slingshot it really comes down to how you like the power delivered, the rear grip is your limiting factor with power anyway. The supercharger kit builds boost with RPM and just keeps pulling more and more towards redline, but you really do need to run it out to redline to get the most from it. The turbo kit we call more of a lazy power since you can hit the gas at very low RPM ranges and get full boost, so if you are just cruising down the interstate and want to accelerate without downshifting, the turbo just pulls away.

For the track or mountain twistys, we love the supercharger kit, super linear power and throttle control, can't beat it.

For everyday driving, the turbo works really well, lots of midrange torque and the turbo acts like a muffler so they are generally quieter.

Fortunately for us, we have both kits and can swap back and forth pretty quick on our test Slingshot, but really you can not go wrong with either of them, they are both a lot of fun. The easiest way I usually figure out which way someone should go is to ask what RPM they shift at when trying to really accelerate, if they say anything other than redline, then I point them toward the turbo. If they say they run it all the way out to redline, the supercharger is going to be more their style.

Hope that helps,

Dave
