Do you currently have a Kraftwerks Supercharger installed? I have a few questions

one thing I learned after owning different sports cars and bikes, there is no such a thing like "enough" power... well a liter bike being an exception, that has enough power I can tell you that

"different strokes for different folks" I guess, also it's really hard to predict future and being able to upgrade things or a bit more headroom never hurts.. it's like desktop computers vs laptops (not sure if it's the right analogy, lol) I always like to build my own systems when it comes to computers and upgrade it as needed

Perhaps they prefer to release fully baked products? Instead of the ongoing R&D that Kraftwerks has, Jackson Racing has a history of just releasing products when they're ready.


@gmsii: I'd love to test your kit at the track. I've yet to have had any Kraftwerks kit owners to volunteer their car for data gathering at the track. We've had plenty of Innovate, Vortech, and Jackson Racing kit owners volunteer, as well as various turbo kits. Perhaps you'd be kind enough to volunteer your shop car for some data to be gathered, so that we can enlighten everyone? @robispec and @sales@delicioustuning.com, as well as countless forum owners have had no issue having me drive their cars.

For the record, none of the cars that participate/compete in the 86 CUP or 86 Challenge run the Kraftwerks kit. There are, however, Innovate, Jackson Racing, Vortech, Greddy, Ptuning, and JDL FI cars.

Mike, I agree with you on gathering track data comments above but you can make sure that I show no mercy to my car when I am on the track and another good thing about the Rotrex units (in general) unlike turbo or positive displacement chargers, margin of error is a lot smaller so while each kit has its own contribution (bracket design, pulleys, IC size etc) but they don't apart like the turbo kits as you know (and that's the reason why you and I both prefer Rotrex units over the others for track use I guess)

if you were local I would gladly let you gather more data too or let you drive for a few sessions, I also do my own datalogging but not with some ultra/pro equipment .. for the record, this is what I did to my header at the last event, I also periodically blow gaskets, ran off track and whatnot and KW kit seems to be running strong, I can even touch my hands on the IC (TB ) piping after a few minutes (which I made it really ugly by wrapping with "gold foil" haha)..so no problem so far, I definitely need KW oil cooler kit and upgrade my OEM oil cooler solution for sure .. and a freer flowing header wouldn't hurt, because mine is cracked wide open

Ambient temps 93F +

Good video and driving etc, curious the gaskets and the mention of the header splitting. Is this in your opinion all from the heat itself that's caused it?

oh I am pretty sure the header failure happened due to restricted flow and high EGTs (or combination of both) so the heat was the factor, many people also had some sort of issue that day my oil temps skyrocketed (my mistake of course but I was , my friend with a Miata had some shifting issues (damaged the fork I think)..etc

so the word of advice, if you track your SCd car get an aftermarket header of some sort..too bad though I really wanted to keep the OEM header as the design and heat shield (well it's OEM ) and I am not really big fan of aftermarket parts, oh well..

[CSG Mike]

@glamcem: those failures would indicate to me that either your EGTs are (way) too high, or you went off during a rain session and the rapid thermal contraction caused a stress failure...

Please get me a log! You should be seeing no more than about 1420F or so. *peak*

Or he's over stressing the header mechanically as I don't see any discoloration from over heating. I'd also check the condition of the motor mounts.

one day i'll pick up a spare stock header and gut the cat.

We gutted the cat without physically gutting it on a complete factory car. Beat that.

Mike, as I mentioned earlier I completely forgot to log at this last event (yeah, I know) .. it could be the combination of both too since it felt the humidity was also a bit more and we had some afternoon showers the day after so maybe it was just my luck.. at this point I am not sure if I should grab another OEM header and give it a shot ..but the guy at the exhaust shop advised me to get an aftermarket one since the lack of flow/diameter may caused this high EGTs.. I am thinking to get a Borla and directly send it to the ceramic coating place in our area (2000F ceramic coating)

I kinda doubt it but I will check the motor mounts too

[glamcem]

@CSG Mike
do you recall what kind of setups and conditions did they have when they cracked the OEM headers?

I've seen headers (and cats) crack/fail from high EGTs with the FA20.

[loogs]

why is my thread being jacked by all you motorheads

lol

considering your agenda and how you have proven to be clearly biased, i think we would have to pass on your offer. also, if we are going to do an on-track comparo, unfortunately even though you would like to think of yourself as the local 'stig', you wouldnt even make our long list of test drivers. You are more than welcome to try and something out with one of the local KW owners and i will be more than happy to arrange a socal RWD hotshoe to handle the driving duties (maybe a craig stanton, billy johnson, or a james safronas type)

your comments are now trying to spin the idea that an SC kit is legitimized primarily based on its track presence. clearly you are grasping at straws. also, in previous posts there are clearly KW owners who take their cars to the track with no problems; and given the number of KW units being sold we fully expect that there will be increasing numbers of owners taking their KW equipped 86's to the track. what are you going to fall back on at that point? just face it, JR has been out designed and you are running out of marketing angles. and why are you so quiet as to the real reasons why the JR kit is not upgradeable?...not even a peep. the elephant in the room is sad that you wont recognize his presence.

and why do you feel compelled to jump into a KW thread and spew your JR spin?

you know what....this is silly and tiring.
why dont we just let time tell all. the cream will rise to the top.
