When running boost heads aren't overly important because you are forcing air into the motor, I'm running stock heads making 901 on 15 pounds. We are turning it up when my trans gets back to 25 and it should make 1100 to 1200. If you are searching for every last HP then everything is important but on a boosted motor just turn the boost up a pound or two and it makes up the difference.

A complete bolt-on supercharger kit is your best bet. I prefer the positive displacement type as they produce steady power and torque throughout the RPM range. Drives like stock. Super reliable.

Edelbrock makes a good kit. There are others as well.

The centrifugal kits like a Procharger are also excellent.

Either one are awesome.

Decision is dependent on the use of the car.

Supercharger: Get stuck in stop and go traffic the supercharger drains the gas tank fast.

Centri: No experience myself but from what I read ppl like them until the belt slips at higher boost levels.

Turbos: Performance commuters choice in larger metropolitan areas

LOL.

I like you.

If that was the case then my tank would always be empty considering how I drive to and from North Bergen and typically sit in traffic 3-4 times a week. I haven't noticed anything critical or anything at all in stop and go traffic. Maybe this was a thing in the old days. But with the tuning and tech we have at our disposal these days I'm gonna go ahead and say this shouldn't sway anyone away from a supercharger. In fact if you're sitting in traffic long enough to burn thru a tank of gas then the best thing to do is drive a commuter car or something more practical and fuel efficient to work.

I'm pretty sure he's pointing to the fact that a supercharger runs off of a belt and is basically a huge accessory sitting on and straining the motor where turbos do not run off of the motor at all.

Very good idea! 100% agree with you.

I got that. But again, it is not anything drastic. I haven't noticed any differences in my fuel consumption. It does run off the engine. However at idle it will be very minimal. And inching thru traffic won't be much of an issue. At least not enough to sway someone one way or another.

First off respectfully speaking, we are talking about a SS with a LT1 engine. Imo it makes more sense to start with the Supercharger and Fuel system first, then do heads, cam, pistons, rods all at once and save a ton on labor unless you do your own work.

Second, with Boost, Ethanol is worth 70-100whp over 93 octane depending on the FI application. Ethanol + Meth his worth 120whp +. So just octane and fueling alone can make up the difference H/C gains on 93.

Third, I could take a stock LT4, 2650 swap it, do FIC +30 injectors, LPE DI pump, Cordes low side, run E60 and make more power more consistently then a H/C 2.3 stock blower build on 93. That is why I don't believe you need a cam first thing even on a LT4 engine. A H/C LT4 with stock blower is very octane limited on 93. The money it cost to do H/C would buy the fuel system and likely have money left over.

Agreed, which is why I started by suggesting that he would be well advised to stay the naturally aspirated, direct injection, LT1 engine design and do a custom valve train, heads, headers, and hi-flows, and gain close to 30% in hp.

Since I own one, typing "LT4" has become habit. Also, I've never in any post recommended changing the short block (rotating assembly) in any way.
