how come... deseal

how come no one really puts a deseal engine in a car when they swap engines? i mean don't deseals have alot more energy in them and can't they take much higher compression than gas engines can? i guess you don't hear of swap engines alot but if you did would there be any real pitfalls of it. or do deseals just not have a good aftermarket as compared to gas engines?

Re: how come... deseal

perception. People still think diesels are slow, smokey, and polluting.

I'm planning a couple diesel swaps; one in a 66 Pontiac and another in a 65 Scout. They don't make good swaps in smaller lighter cars typically because most diesels that are readily available are heavy. You wouldn't want to replace the 400-lb small block in your Camaro in favor of a 1000-lb Duramax.

The VW TDI makes a good swap in smaller cars. The VW V10 diesel from the Touareg is very nice but expensive.

Given I get gagged when driving behind any diesel, old or new, I still think this perception is largely correct.

Still, you are correct, there are few reasonable candidates for swaps.
Furthermore, most people swap auto engines for performance benefits, not for the greater economy and torque of a diesel.

The exception is diesel swaps in light trucks, which do make sense for heavy duty use............... so long as you steer clear of the tailpipe

I doubt you'd know if you were behind a new diesel vehicle. Without the noise and smoke you're looking for, how would you know?

There are many diesel engines swapped into vehicles worldwide, the US is probably the country with the lowest uptake. Partly because GM made some of the worst diesels the world has ever seen.
In fact my vehicle was originally petrol, had a 3.5L V8 petrol thrown out and a 3.9L turbo diesel thrown in.
I'd never go back.

I'll take you for a ride in my Bonneville once I get the Duramax in it. It will be putting 600 hp to the wheels and over 1000 lb-ft. I'd call that a performance benefit.

if they are running diesel fuel, I agree

Put biodiesel in them and they stink badly. I hate being stuck behind them on the bike

if you start playing with the computer though, they can get pretty stinky too. Around here, lots of people like to crank up the fuel and then rev the engine a lot to see the pretty clouds of soot.

By "lots of people" you mean rednecks?

I don't see how people can think blowing black smoke is cool. For a start all that soot is very bad for your engine, let alone the air we breathe.

Re: how come... deseal

how is the soot bad for the engine.
the soot is a byproduct of the engines incomplete combustion of the fuel.
...

the only engines that diesel soot would affect in any way is the engines of the surrounding cars. lol

Re: how come... deseal

There is actually very little about soot that harms the atmosphere. It is very harmful if inhaled, but it is so heavy that it settles to the ground before it usually does any harm. Its about as harmful as cigarrette smoke; carcinogens included.

hehe, you'd have to ask them if they are rednecks....you can get pretty impressive power increase with such tweaking, and some truck owners think they suddenly have a hotrod after the adjustment

Re: how come... deseal

Here's the recipe

LB7 duramax
Quadzilla tuner
K&N intake
5" exhuast and 4" downpipe, stock cats.

That's enough to put a 7000-lb truck in the mid 12s with NO smoke except the tires . I don't care if you're a redneck or not, that's impressive.

Re: how come... deseal

hehe, I knew that would rile up some diesel lovers

I've seen a lot of trucks with tweaked systems at the strip. Never seen one in the 12's and NOT smoking like a chimney

Guess our rednecks are different than yours
