I started with a Kenne Bell 2.2 Flowzilla, then switched to a Vortech SQ. Around the same time I switched to the Vortech, I built a 306 with TW heads, stage 1 cam, Track Heat intake. Had a Tremec with both. Broke the input shaft, switched to a C4 setup. Only dynoed with the Vortech and C4 with a 4400 stall. Dyno read 475 at 12#s boost (which really isn't accurate at all with such a loose stall). Ran a 10.80 with a 1.57 60ft. at 126 mph weighing 3600#s. Just switched to a turbo, cause I was at the point where I really needed to step up to a YSi. I got a nearly new turbo kit for less than the YSi headunit. The kit came with a 76mm turbo, which I have discovered is just a little too laggy for my taste. I will probably keep the 76, but I just bought a 67 last night. No times or dyno numbers with the turbo yet, as I just got everything together.
K.B: loads of torque really fun on the street, easy to spin Drag radials at will, makes alot of heat, clean install. If I were just wanting a nice torqey street car, this is the way I would go. Resale value holds very well, boost is easily changed with pulley swaps. No real belt slip to speak of, if you do a few mods that are documented here. Power seemed to level off in the higher rpms. Never had a minutes trouble with the kit. 17* timing (93 pump gas no meth kit)
Vortech setup: I loved it. Power is very linear, making application a lil' easier. Pulley swaps are easy. Seemed like I did alot of upgrades to get to where I wanted it though. Had to send it back a few times, to get new bearings. Sounded good, everyone knows what it is. Made real good power, and just keeps on pulling the more you spin it. Meth kit worked good with the Vortech. (22* timimng, with meth kit on 93 pump gas)
Turbo: So far I'm liking it. No belts to fuss with. Nothing pulling on the crank. When the boost comes on, it's like a freight train, it just keeps pulling and pulling. Intercooler makes the charge nice and cool. Initially routing things as to not melt is kinda a pain. Making sure you get the right size unit is the key to happiness. Blow thru setup with a nice BOV sounds cool. I love hearing the thing spool up. Seems to make mad power at the same boost level as the blower setups. Nothing to really complain about as of yet. One plus though, you can get a new unit or parts or service of turbos for alot cheaper than either 1 of the blowers, which I think is a huge plus. Like I said I got a complete kit for less than the price of a YSi head unit only. My car is more drag race oriented, so hooking on the street really is out of the question anyway. I really didn't hook with either combo at all on the street, even with MT drag radials, which work awesome on the track. This was with both the 5 speed and the C4. I did switch from 3:73s that I had with the blowers to a set of 3:27s, and the street hook is still not there. I do plan to run my meth kit with the turbo, once I get everything sorted out. (22* timing, 93 pump gas, no meth kit yet)
