Need a plan for an SC mod? Details inside

[DJCarbine]

Also to add to the boost debate, I'll have to check over my logs from winter/summer but I'm pretty sure I had up to a half PSI if not more difference due to the temperature of the air. Since a wastegate is not regulating the boost, its really dependant on ambient temps and possibly even camshaft timing/tuning. Enough to notice on a boost gauge? Maybe....

Boost leak test kit would be the best way.

That is definitely the best way to find one, once you know you have one.

I knew about the V3 issue some people have had with tracking, did not know about the warranty drama. Seems like its getting taken care of so there is that... I know he had a vortech rebuild thread going but didn't revisit it, I may have to beat him to the punch as I plan on doing a teardown/rebuild over the winter for fun and to see the condition of the bearings.

yes, cats on the header and extended track use is not a good combo

And you are wrong. Plenty of "FI Owners" do not own their cars.

Right, set it and forget it, while performing proper maintenance. A CARB Tune is not supposed to be tampered with, and with the linear power delivery of a supercharger you shouln't see any boost spikes. If you do have boost spikes, then you won't need a boost guage to know there is something wrong with your car.

Turbo-charger maintenance and supercharger maintenance are two different animals.

While I would say it would be wise to get a boost gauge and wideband for a turbo, to run a CARB tuned supercharger (Which is all he needs to meet his goal) all of that stuff is not necissary and probably because you want to be the cool guy in the parking lot.

While I agree with you most of the comments above I have to say linear power delivery doesn't have to do anything with the boost spike, I had boost spike with OEM turbo cars (STI) and many people had boost cut with their stock turbo Evos with linear power ..

boost is limited by the pulley size so boost spike/creep is not an issue with Supercharged cars (even with full exhaust and aftermarket header)..

I wouldn't bother with a boost gauge to see if I have a boost leak, there are other ways to tell if there's a boost leak like some of you mentioned (noise, power loss) you can use one of the track app that reads the engine data and/or use virtual dyno to see if there's a relative loss..

I also wouldn't bother with wideband gauge but wideband O2 sensor might be good for the better throttle mapping..

I would be more concerned about the Oil Temps and Oil Pressure and monitor them instead.. FYI ,Torque App is really accurate for oil temp readings

Were saying the same thing differently. What I was referring to was: In a supercharger system, boost is dependent on RPM speed because of the pulley system thus a linear power delivery.

Only that it isn't linear.

Don't get me started on the definition of linear. Just let the supercharger owners think what they have is linear.

of the first degree with respect to one or more variables (2): of, relating to, based on, or being linear equations, linear differential equations, linear functions, linear transformations, or linear algebra



And.... You're welcome.

Keep trollin'

[s2d4]

Ohh boy...

[tahdizzle]

I can't speak for the rest of the community, but like I mentioned before, when I say: Linear Power Delivery. I mean that the power delivery is a direct relation to the RPM.

Thus the definition I provided of the word "Linear".

You won't drag me into this discussion again. The last time it resulted in having to explain y=mx+b, and we all know that doing math in public is always a bad idea.

back on topic to the OP ignoring these ...y=mx+b arguments.....have you settled in on a build yet?

after finding out how long itll take to get phantom, i think im leaning between kraft, innovate, and JR.

-JR seems to have the least problems(found on this forum to my knowledge) and seems to have decent speed on the bottom end.
-Kraft is the heavily favored SC at the local shop i intend to get it tuned at, they have had alot of great experiences with multiple customers saying the same thing about the kraft model although(through this forum) it seems to have the most problems, most being small things tho like parts missing.
-Innovate as the most low end power, and being someone whose just a DD, i wont find myself pumping that 6-7k RPM daily. However, like krafts, it seems to come with some problems that the JR kit just doesnt seem to have :/

let know how to work things out OP! im curious to see what ya do! for my own knowledge :]

[sissupr]

To the OP. Used vortech kit, tune, upgraded pulley = under $4k. Installed myself without ever doing it before. Its not that bad... just need a friend for extra hand and moral support lol. Good luck with your decision.
