Positives & Negatives On Kraftwerks Supercharger vs Jackson Racing Kits
Just as the title says any info is appreciated... I'm daily driving not tracking the car so I'm not looking to go above 300hp with a big blower. I'm asking more about the longevity of the kit and which one would be more suited to last a long time without prematurely blowing the engine. Obviously shit happens but wondering which is my best bet from your experience

Not blowing the engine will primarily come down to the tune.
If whp is the primary goal why go supercharger over a turbo? Reliable turbo set ups do exist.... I think. If I was a track junkie the JR kit would be the one to go for. The C30 with E85 should hit your whp goal. If car shows and bragging about peak numbers are your thing then go KW or top mounted turbo. While CSG would look biased saying these things, being a KW owner I dont know if I would. Everything has it's pros and cons. The JR on the surface seems reliable(i honestly havent checked and I'm not going to), but its dog shit ugly to me. The KW kit looks much better and can be easily upgraded to the big C38 blower but has quality issues. I.e. the directions leave a bit to be desired. They're constantly making revisions and have come a long way since the release. That said I haven't had any issues at all with my supercharger. Make sure to take a drive in a car powered by a rotrex before you buy. The top end is great but I wouldn't buy a centrifugal supercharger for the street again. My car is my toy car and I primarily use it to get groceries and cruise around the lakes up here, so I dont spend any time in the fun part of the powerband :-( a centrifugal was a waste for me, should have gone turbo.

This post is going to be biased, obviously
I bought the JR kit because it came with a reliable tune. Tunes are the biggest variable for any FI when it comes to reliability, so I knew I could trust the guys who built the kit rather than my local tuner or an e-tuner. I'm not knocking e-tuners or tuners in the NY area, I just erred on the side of caution. The JR kit has little room for upgradability though. I believe you can upgrade the blower on the KW kit, so if you think you'll want more power later on, you should consider that kit.

One will leave you stranded one wont... We personally push the KW kits so like mike said above, we would be more biased towards them. BUT both kits run the same blowers. the blowers themselves are great. my kit at over 450hp at the hubs have been issue free since the new pulleys, thats about 10k miles on the kit, the first 1000 i did go through some belts, but KW told me i would due to the small pulley. but when my belt broke, i was able to keep driving until i replaced it. no other SC kit out does that. That said i personally dont think you could go wrong with either kit. I know the JR kit is good, i just prefer to not be stranded if/when the belt breaks

Some try and knock the KW belt as being a sewing machine belt, but going to Gates website and looking at the belts, they offer 3 different versions of the model we use, the lower grade is in fact used for a industrial sewing machine, but the one we use, and even the one under the one we use is for variable speeds on loads that should be much higher then what the SC sees. so that just a myth, i know of a car that had over 400hp, driven very hard for about 20k miles and not one belt issue used the big pulleys the whole time. -Thomas |

Having installed and driven both kits, but do not own either I can give my less biased opinion.
The JR kit is great quality and fits well, it is easy to install and uninstall if need be. It's CARB legal, that's important to a lot of people in California, where I'm willing to bet a majority of 86's were sold. Jacksons customer service is awesome, and they stand behind their product. I have yet to see a major issue with one, and that says a lot. Their oil cooler setup with the rotrex cooler is also genius. Cons to the Jackson kit for me, were the original silicone throttle hose(since redesigned), the cheapish plastic diverter valve and just the Rotrex in general. Its not my personal favorite centrifugal blower, but it seems to be doing well on these cars. Also the bumper fitment on the drivers side can get tricky with the Intercooler pipe, especially with fog lights. The kraftwerks kit looks nice. The upgradable larger blower is neat too. That's really all I liked about it. The quality of the components seemed good, but the MAF placement is aweful. Price I guess is definitely a plus; it is on the cheaper side. Bumper fitment sucked with their stupid Intercooler bracket design. Running a ribbed belt off the front of the crankahaft is horrible, and the belt is noisy as hell. I don't understand why they keeping making the argument that their kit won't leave you stranded, they have more belt issues then any other kit. You get lucky if that belt breaks and doesn't take other things out with it. It could easily get wrapped around the accessory belt and cause hell. Worst of all, I know that at least in the BMW world, you could not run a ribbed belt on a rotrex blower and keep your warranty, I don't think that has changed(maybe?) but that is why I do not reccomend the kit. Also, how long ago was it promissed to be CARB legal? Last edited by The Racers Line; 03-11-2015 at 09:29 PM. |

In the context of a belt breaking on the JR kit, however unlikely it may be, and I have an extra belt on hand but am on the side of the road....is re-applying the belt an easy process? I assume you should have necessary tools on hand at all times in the trunk, but I am wondering in a worst case scenario what can and what would have to be done? Perhaps @CSG Mike can add to that too? I am just curious how it would play out if the worst happened in a belt breaking related scenario. Thank you.

KW comes with an intercooler that looks a lot less efficient than the JR.
Not sure if there have been any belt issues with the JR kit? Rotrex does not recommend a cog belt and downright warned against hitting a hard rev limiter if you have one. That is MY personal experience so far. Both kits are better than anything else out there at the moment. |
