I would save your money, cams not going to be worth the $ for hp, if there is even a noticeable gain.
I guess my term piggyback is not correct...but that is what I have always called the electronic device that you add so your stock ecu will continue to function correctly.
I would sell that guy your piping, and since it is so great...charge a premium.

 

I no that fmic are not welcome in the SC crowd. It obviously wont give the best dyno number. But i dont think im totally of the track in what i said.

On my low boost previous setup. When i had the aftercooler i dynoed 297 whp. Like i said previously , after 2 heat soak at the track my friend with is NA s2k was faster then me.

Kraftwerk and hks both use the fmic with their SC kit. They probably did some research ... ???

These piping are pretty cheap. Their is not alot of kit that i know of. But like i said. Make me a reasonable offer and i will take it.

 

I agree that they are not welcome in the SC crowd, as I mentioned before the only people who urged me to go that route were the people selling them, everyone else was against...the reasoning was the loss of boost was not worth the few degrees of cooler air. Now that may not be such a big issue in regions with milder temps, but I live in NC and 90+ days for weeks at a time are the norm...it may cool off to 75 at night if we are lucky.
I also agree with the heat soak issue, the water gets hot and you really cant install a large enough exchanger to make much of an effect. You mentioned track use, that would be the extreme. However, just cruising on the interstate at 80mph for an hour and you have zero cooling...the water is hot and cant cool. With all of that said...I pulled my SC kit off and installed a turbo.

 

2 questions:

1.) i'm having my motor rebuilt and plan on getting it tuned right after, would the community drive the car with a base map and new engine to the tuner thats about 6+hrs? ; and

2.) is it worth a tuner to break in the motor on the dyno?

 

Its funny hearing all the talk about FMIC and how they are not welcome in the SC world. They serve a good purpose just like an aftercooler. If you are pushing a fair amount of boost and plan to do a few back to back runs or track duty then a properly setup FMIC will be a good choice for you. On CRSX forum the SC guys would love to run a FMIC with their roots blowers but don't have the option. I came from that world and have run several roots kits and a custom twinscrew kit and in the end I always wished I had a FMIC due to the heatsoak issues. I have a FMIC on my S2000 Vortech setup and love it for all the reasons mentioned. Its a product with a good purpose and should not be so easily tossed aside. Just my take on it.

 

any chance you can let us know the size pulley you run, the blower head unit, and the boost you actually see?

 

Sure....

I am running a Vortech with the upgraded SI trim currently with the 4.5" blower and 6" crank pulley seeing 7.5 at 8200 rpm. FMIC is piped at 2.5". ASP is currently making me a 6.5 cp and 3.8 blower pulley which I hope to have soon. Below is a breakdown of my current boost plot.

 

I have a 3,4 inch pulley on my novi1000 on an ap1. As per Sos chart it is a 10psi pulley on my ap1 at 9k. I don't have a nice graph like ^^^^ but i saw 9.2 psi on the dyno with a fmic.

I have to admit that from what i have read i didnt think it would pass 8ish psi

 

Is there any benefit or downside on a SC install to venting to atmosphere vs recirculating?

 

May need to recirc if you live in CA if you are trying to maintain the CARB certification. I ran both, no performance gains or losses, that I could tell.
