So i have this LT1 that is asking for more power for x-mas... Looked into H/C setup (plenty of info there), but I was just wondering what the options were for superchargers or turbos on an LT1. I'd like to see boost/power capabilities and just some overall pros and cons of each system. Don't necassarily have specific goals in mind; just want more power and couldn't really find much on FI. BTW, its not for the track, just the street.
Please, no stupid opinions based on no experience or knowledge!!

Thanks guys

 

You can take a look at my build and what it does, it may give you some thoughts.

Just click on the link below.

 

If interested I have a COMPLETE D1 Procharger kit ready to bolt on an LT1 F-body, if interested PM me and I will give you full details, going on Ebay proly this weekend...

 

Go to the dyno meter section, plenty of post, even be it LS1, the cost and percentage of gain are general the same, it is something that is searchable

 

turbo > heads/cam see sig

 

Boost usealy gives the best peformance you can get short of swaping in a huge *** motor. But most of the off the shelf stuff i see around here costs alot more money than alot of us have in purchasing our cars. If you are handy with a welder and know the basics of tunning a FI car there is alot of power to be had with boost for cheap. Just how cheap it is depends on your parts availabilty and skill's/tools though.

 

Unless you have the large budget needed to do the forced induction (turbo or supercharger) thing work properly, I reccomend going with the heads and cam combo you were looking at earlier.

Stock LT1's (and LS1's, and LS2's for that matter) were not meant to handle boost from the factory with their non-forged internals and high CR. You can boost a small amount (say 4-6#'s) for a while with all the supporting mods (fuel pump, intercoolers, methanol injection, ignition, dyno tune ect.) and you'll probably last for a while, but I doubt you see the same mileage before a rebuild as you would by staying N/A. Even then you are still out thousands on a supercharger, and probably thousands on the supporting mods, and with that small boost amount, you won't see much of a power gain so its not really cost effective. If you wanted to run more boost, then plan on a rebuild in your near future. Some guys swear they are doing it, but they are usually the ones who have only done it for 5,000 miles as I have yet to see anyone run even a moderate amount of boost on a stock bottom end and last a bit of mileage. You might make it 25,000 miles, or maybe 2500 miles, but every time you put the hammer down you are rolling the dice, and eventually you will need a rebuild.

Now, if you have a budget to do it right ($14,000-$20,000) depending on what parts you use to build the motor. The cheep end would be to use parts like Eagle, and Summit. The expensive way would be to use parts like Oliver, or Lunati. Then you can build the motor with forged internals, and a lower CR enough to handle the boost. You will also need to build your car up to handle the power levels like getting a new rear end, tranny/clutch, driveshaft ect. ect. Not to mention if you want to try to hook up with that power you'll need to get some suspension mods. And you'll still need the supporting mods that I mentioned earlier.

Long story short, its not cheep to go boosted.

 

i agree with CALL911... I was thinking about doing boost then thought about things like what he said, so i did a head and cam build.. worked great...
