It seems that a completely installed and tuned heads and cam job is going to cost about $5500-6k.I think you can get a ATI or a Turbo Tech for about the same if not a bit cheaper.How does the ATI feel compared to a good heads and cam setup?If both were to make 425-430 horse,does the super charged car have more low end grunt below 3000 rpm compared to a lopey high rpm heads and cam car?Im guessing driveability is better with the charger?

That ATI kit looks really nice and installation looks easy too, a lot easier than heads and cam.I was thinking if you were to blow your engine with the charger it would be easy to de-mod to stock and take to the dealer.In the future just change the pulley, put in another PCM and injectors and up the boost for 500 hp.

Do both

that was the same question i faced: which one?
But FI has more potetial, that and i picked up a turbo kit real cheap.

You should take the question one step further: Heads/cam vs. supercharger vs. turbocharger.

It should be the turbo. I don't know which would be next, maybe the heads/cam. To find out, print out some representative power graphs of each setup. The ultimate power numbers should be close, but its the shape of the torque (not horsepower) curves thats more important. Overlay the graphs and see how much torque is available from 3,000 to redline, comparitively for each setup, and that will be a good indication of the car's ability to accelerate, everything else being equal. Although, with an automatic, and a high converter, there should be less of a difference.

The FI stuff has the advantage of being easily upgradeable. How many of us are satisfied with our current power levels for very long anyway?

Let me throw in one more thing: I still can't believe that the supercharger companies can charge as much as the turbo companies. I can guess at the relative cost of the items, and I got to believe that the turbo kits cost more to make. I guess its all due to comperable performance, not manufacturing cost. ATI has got to be making a killing on their stuff, because they can.

Yeah that Turbo Tech kit is nice. I heard a turbo car can put out huge amount of torque below 3k rpm like 500 ftlbs. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> The thing I dont like about the turbo is putting a hole in your oil pan.Its not bad but I would perfer to take the pan off to tap it.

How reliable is a blower if you keep the power conservative (low 400 rwhp) level?

Please save yourself a lot of trouble if you want a turbo and get the upcoming LS1 Motorsports kit.I'm still surprised a lot of guys who brought Turbo Technology kits don't speak up about the difficulties they have had with it. Rob Raymer seems to have adressed every problem with his upcoming kit,but he sure ain't the only one that has almost completly rebuilt the things, trust me I KNOW.......

How many stages is the Ls1 Motorsports kit supposed to have? What kind of power are they trying to make?

with forced induction you maintain idle quality, gas mileage, and overall driveability.

Also if you use scavenge pump like the Incon cars do, you can route the return oil in the drain hole or the oil level sensor location. Incon does not do it that way, but it will work. I would say Turbo, supercharger, then NA on what hits the hardests. Also Robs kit should be loads better than the Turbo Tech kit.

Heads and Cam you get 425rwhp and thats all she wrote. FI you get 425rwhp, and once that gets boring (which it will) you crank the boost a pound or two and see another 30-40rwhp. A 3-4psi twin turbo kit, for example, will show you 425rwhp, while you can safely run (if your tune is correct) up to 9 or 10 psi). I am running around 7psi or a little less with my Incon kit and a very safe (read rich) tune and I make close to 500rwhp on the dyno. based on track results I make well over 500rwhp because my 3850lb car runs 125mph through the traps. Plus, I get stock gas mileage and while driving around town I would never even know that I had any power adder...it looks, feels and sounds like stock, until you hammer it.

I remember picking my car up after the twin turbo install and cursing out Incon because I thought I'd been jipped...then I got to the highway andf opened her up and I haven't stopped smiling since. Go forced induction...it's a world better.
