H/C/I vs. Supercharging

I have a 94 GT (AOD) and need advise as to which route to go. I preliminary research shows that they both cost the same. I love the sound of a car with a nice cam but then again I love the whine of a supercharger.
 
The s/c will give you more power, but I'm doing an HCI right now for the following reasons:

1 - My engine turned 100K, needs some freshening anyway.

2 - Its easier to do an HCI then a power adder then the other way around, and I plan on doing both eventually.

3 - It will be a good learning experience as I'm somewhat of a rookie and doing it all myself will help me out big time.

4 - I thnk it will be more satisfying to go fast on a combo i researched and designed rather then a bolting on a s/c in a weekend.

5 - Lopey cam > s/c whine.

My vote is for the supercharger (for lower mileage engines)...I'm faster than all my friends with HCI and my idle is rock solid. If you're looking to rebuild your engine due to miles/age then I would do HCI first.


Sorry to drift off topic...How much power does your combo make? Its very similar to mine...

Never had it dyno-tuned so I don't really know. Just to get an idea, I beat my cousin's C5 vette with CAI, Pulleys, Cat-Back and I've turned 109mph in the 1/4. That same night my cousin's vette turned 104mph.

That can be done with H/C/I.


I think its up to you on which you like. I myself love the whine of a blower... and even more the sound of a turbo on a v-8. BUT, when it comes down to my car i prefer N/A power. Lopey cam + high compression + a lot of CUBES = :drool:


And right now i dont have as much time to tinker with the car with school and work. So yea it does take longer to build a motor h/c/i wise, but its much easier to tune it and maintain it IMO. Dont get me wrong though...down the line i will have a blown/turbo'd car :spot:
 
A blower can be installed in a day and would be much easier/cheaper then h/c/i to install. Then start spanking N/A cars all day. My car with stock h/c went 114.5 on a hot day and it was the only day ive ever brought it to the track. Imagine what it could have done with a tune and cold air.
 
FIrst..You have an AODE

With that said, If you are not too mechanically skilled (like me) and you want some quick power..go S/C.

Just remember it costs more than a kit, with the little extras you need (gauges, tune, fuel pump, injectors-if you dont want the FMU-).

I have the S/C, but I want more....Looking back, I should have built the good combo first, but then again, I wouldnt have been so quick all along.

I agree with what most others have been saying. I had plans for both so I did H/C first (I just kept my cobra intake) because I had 100,000 miles on the car and it fresehens it up plus.. It is easier to add the blower on after the heads cam intake rather than taking all that blower mess off later to put on the H/C/I. As far as power goes on just one or the other you will make substantialy more with just the blower rather than just H/C/I
 
From someone who did an HCI recently (me), I would say go with a SC kit. For me, I like NA power and the challenge of completely rebuilding the top end of my engine. But if you are looking to do both eventually, the you will have to do the bottem end too. And frankly if would be far easier to do the top end while you do the bottem end. Plus, going SC first will help guide your top and bottem end choices.

Not to mention, you might just find you have enough power with a SC alone, and opt out of further mods down the road (hehe, not likely - you can never have too much power!!!).

:stupid: If i did want to go blower and i couldnt do the bottom end(if it had a lot of miles) at the same time, i would do the SC first then upgrade the heads and bottom end later down the line.
 
After redoing the exhaust this summer, my next plan is to rebuild the engine - 128K and she deserves it - dropping a S/C on it and bragging is BS - I want to do it the right way. I want her pushing 300-350 without an adder to when I do do it it's making the power I want.

Granted I have NO CLUE what I'm going to do for the combo, but when the money comes, so will the research.
