I am planning on making another upgrade to My SI. But at the moment I am really not sure if I want to go supercharged or Turbocharged. For the past few years I have been saying that I was going to get the CT-Engineering sc with the Vit After cooler. But at the same time I would love to be turbocharged. My biggest question is for all the people who are F/I what are some tips on your builds. Give me some pros and cons, or some good ideas I am mostly using the car as a daily driver so I am not looking to hit 500+ HP and I am mostly going to do drag racing.
 
For daily I would honestly suggest going with a supercharger. It won't net you as much peak HP, but the boost is almost instant and you will have a much flatter and more predictable torque curve, and it can still be fun at the strip.
 
I would want one that is going to be more predictable going though the rpm range, if used as a daily driver. I wouldn't want something to kick in while I'm near max speed for what ever turn I'm in.

That's why I was leaning towards the Supercharged set up. And what I am kinda seeing from some forms is right out of the box the Kraft is making more top end HP but less torque then the CT-Engineering but the ct makes a more solid power curve correct me if I am wrong.
But the set up I am looking at is the CT stage 2 with the 750 injector(do you think 750 is overkill?) from ProCivic. Then later on get the Vit after cooler.

I thought the full race turbo kit spooled up fast.
 
IMHO:

CTe - Solid kit, no aftercooler in basic setup. Install seems pretty straight forward.

KW - Everything you "need" in one blast, includes aftercooler. Good luck on getting all the parts the first time.

Turbo - Interesting option for 300-350hp builds, install more involved (drop subframe, etc.)

I still dont know myself, lol
 
When comparing the stage 2 CT to the Kraft. Dose anyone knows what kit makes more HP/Torque.
I know the website says the Stage 2 ct kit should put me around 270 whp, and the Kraft kit should put me around 330whp 240 Ft lbs. Was just wondering if anyone has done a Dyno pulls with just basically just the kit.(I have seen Vits page I would like to see some others to go off of)
And like the CT kit how you can add the Vit After cooler that helps add a few more is there much more that you can do to these kit other than fuel or Pulley's?
 
I'd say supercharger, perfect for a daily driver and still tons of fun. Plus, simple install.
 
So with the CT kit I should be around 265-270, before the ZDX throttle body 2.95 pulley and the Vit after cooler. I am probably going to wait a little while longer to get the Vit after cooler.

But after the vit after coole, pulley's ZDX throttle body, and E-85 will the Ct make more power then the Kraft's kit?

you can go e85 gas like sleepingpanda

I spoke with Panda and he told me about his build. He has the 1500 injector's with E-85. I was planning on running E-85 lucky for me it's about 1.50 cheaper then 93. Either that or they have 110 at are shell station. But that is about 5.99 a gallon or more.
 
Panda said he gained another 30hp or so when he went e85.
 
I have the 3.15 pulley with no cooling, ZDX throttle body and PRL's SRI, and I'm making about 280-285. A buddy of mine has the aftercooler, 2.95 pulley, and a CAI and is making 330.

Where are you at? I'm in FL and I'd be concerned my IATs would bogg me down without the aftercooler.

Ah ok I was subtracting from Vits post of his after cooler but he may not have installed the ZDX Throttle body, and the 2.95" pulley yet. What size Injectors are you using?
