Hey guys I've been looking at the performance & machine design predatorperformance1 which it is a 670 which makes 43 horsepower at 4700 RPMs and makes just under 50 ft lb of torque from 3500 to 5000. Or should I build my own predator 670 to make that same amount of horsepower and torque naturally aspirated just like the predatorperformance1 depending on which one would be cheaper. And then afterwards I'm thinking about adding a turbo just like carsandcameras did on their build and then possibly change it from pump gas 93 octane to methanol just like they did but then one other thing I'm thinking about doing it adding nitrous so then it was spool the turbo easier even though they didn't do it on theirs. And then I plan on buying the gopowersports vintage go-kart roller kit and then buy full face DOT motorcycle helmet and motorcycle gloves and supporting neck brace which is all the safety equipment that gopowersports recommends

I'm doing this on my phone and it has no feature to autocorrect to make it correct

Sadly I don't have autocorrect in my head and autocorrect sometime doesn't work on my phone

Hard to believe you have been a member for more than 2 years. How old were you when you joined, 12. I say this because your rattling on about a turbo, then nitrous, and methanol no less to a industrial engine, you sound like a 14 year old kid who has watched too many Vroom Vroom videos. With or without auto correct you should be able to do a LOT better with your writing skills, even if you're only 12. Sorry for the negative criticism, but your post comes off like that.
If you are interested in building something a little more realistic, there is a lot of help available here.

Well I'm almost about to be 21 and this is how I usually am when I type anything out no matter what

Okay, I've subscribed to Cars&cameras for a number of years, I follow a lot of their projects, the drag monster is a very expensive one, it's financed by sponsors. Take a look at Red beard garage to gain some insight into the actual power gains from a 670, then think about a cheaper duromax440 and work on that instead. Paul's karts has a few videos on built engines, these are in the $3500 range as a complete unit.

But I'm thinking either build it just like they did before they threw methanol on it we're building like how they originally built it in the playlist that they have on YouTube or build it like the turbo methanol build that they have or build it like the turbo methanol haltech build just like it is right now and have a torque converter or a clutch on it like they have I don't know I'll figure something out but I would do something similar to what they have

I have a question when do you recommend a torque converter and when do you recommend a centrifugal clutch?

A disc clutch will basically handle anything you throw at it, the Iame, Rotax and Aixro engines all use centrifugal clutches. Torque converters are used because they give variable transmission and a softer start, minimising stress on the engine and output shaft.
Torque converters are bulky and heavy, clutches are lightweight. Both wear due to friction loads.

So a disk clutch is the best way to go? For being able to handle all the horsepower and torque?

What centrifugal clutch or torque converter will work with the Gopowersports vintage go-kart roller kit?
