Hey

Which Turbo is Better as in More Power..

Front mounted Turbo or Rear Mounted

 

The way I hear rear mounts have a ton of lag

+1 for front mounts

 

raer mount will have more lag. heat is a big factor with boost so the amount the exhaust cools off will affect that. but you could help by wrapping the exhaust to keep the heat in. but then you have to consider that front mount usually cost more bc of custom headers-and having to remove ac, etc. each one have there plus-minus. rear mount setups are easier to build yourself as long as you have a welder and some mandrel bent piping

 

Very true. Easier and cheaper to build but not better.

 

Theres a handfull of rear mount cars out there making good power and running prety quick. But if you look at all of the fastest turbo cars, they are all front mount.

 

But if i get a Front mounted Turbo...Does that mean i have to take out the Ac and someother stuff?

 

Who sells Front mounted turbo kits for Lt1's??? other than ebay...

 

??????

 

Depends on the kit, pro Turbo Kits had a complete system that kept a/c, dont believe they are a sponsor any more on here though. Look at SpeedInc, they have a turbo 96 SS

 

it basically boils down to how much do you wanna spend, how much power you looking for? you looking for an all out drag car or a quick street car on a budget

 

Power or convienance...pick one

 

There's a reason you don't see a rear-mount setup qualifying in the top 16 at a FFW, NMRA or any race for that matter.

 

If you would research engineering forums concerning turbo efficiency, you could answer your own question. Exhaust contains 2 types of energy: volume of gases, and heat. Both types of energy can be used by a turbine. Since the exhaust pipe of a rear mount will always dissipate heat, part of the useful energy will be lost. This makes a front mount more efficient, 100% of the time. More efficiency=more power per pulse.
However, I find your question somewhat simplistic, in that it ignores several key factors. They include, but are not limited to, things like:
How crowded is your engine compartment
How much heat can you endure under the hood
How willing are you to install custom exhaust manifolds
How willing are you to install the extra piping required by a rear mount
Where are you willing to locate the air filter
Are you going to use an intercooler(s)
What pressure can your engine withstand without becoming a grenade

Lag can be engineered out, and has been done so by STS. This is a myth. My 84 Daytona had lag. My STS does not. Other considerations, such as how to run important lines, such as oil and electrical, should also be taken into consideration.

Please understand, this is not intended as a flame. Rather, it is a physics/engineering-based response as to why owners should base their decisions for the location of their turbo. What you choose is up to you. The front mount, just due to physics, will always be more efficient. However, the rear mounts offer several advantages to those who do not require the ultimate efficiency from their turbo.

you guys make me happy. You don't know how many wasted posts on other sites I have made that have just fallen on def ears.

 

haven't seen any front mounted turbo kits for lt1's on ebay, but I might be selling mine comeing up just around the corner.

 

Rear mounts are only good because they are out in the open and u don't have to worry about under hood temperatures. However i hear they lag like a **** compared to front mounts.

 

My vote is rear mount. Do a little research on squires rear mounted turbo's.

FRONT FRONT FRONT. If you can at all help it/afford it go front mounted setup.

It is proven in real life test that a front will make more power.

But at the same time for a quality turbo setup for a good price, it is hard to beat that rear mounted setup. Im out to change that though...

 

Rear mounting is for prison sex, not turbos.

 

Theyve had great debates in the FI section about this. Ive seen some get locked because they got so heated. I say both make power and I wouldnt count the rear out though it's not a setup I would go with.
