supercharger

[Guest tae]

Can you install a supercharger on a 1991 Buick Reatta it has the same engine as the 1996 Buick Riviera which is supercharged?

This engine swap has been done by a few people on this forum.

Many posts on the subject but the L-67 (with boost) has a different crank, rods, and pistons (lower compression) and a stronger transmission. The 1991 engine will accept the supercharger but requires a remapped PROM.

Of course for about the cost of a swap, you can buy a Fiero and go faster.

I have modified my opinion of superchargers slightly. On an SI engine they still belong above 20,000 feet but are OK on a CI engine and think the future is CI.

I owned a 2000 Regal GS for six years. If it wasn't for electrical problems, I'd still own the car. One of the sweetest engines I have had the pleasure to command. Why manufacturers prefer to turbocharge and not supercharge baffles me. And why superchargers are not incorporated into new engine design also puzzles me.

Are a lot of reasons, some engineering (compatibility with PON, need to reduce the compression) and a lot bean-counter (supercharger/turbocharger is not cheap).

Also it costs less to turbocharge than to supercharge (particularly blow-through designs).

Now that I have one am really starting to appreciate turbo diesels but a lot is that the engines are designed for a lot of compression and run at WOT constantly. Modern ones are much better than the 240Ds that could not exceed 70 mph.

Latest BMW 3 liter that is now being imported develops over 400 lb-ft of torque.

Back in the 1990's there was someone who was selling CI engines for experimental aircraft and the reviews were positive. He planned on building them for certified aircraft but I never heard anything else. I bet when he tried to get his engine certified the costs were astronomical.

i checked that out.too bad the pics are gone.

Whatever yo do use a full engine, not just the supercharger. It will last longer and be an easier swap.

I will let Philip know when I see him tomorrow, I beleive he used the AOL space for the pics, and since AOL closed all that down in October it isnt up anymore.
