170 slant six turbo build / cheaply
The turbo trans am was also a draw through. It was a dog.
True. I wouldn't build a draw-thru setup for the street because of the intercooler explosion possibilities, but for racing-only, they might be okay.
I know it's possible to make considerable horsepower with draw thru setups because of examples such as Buddy Ingersoll's 2-liter Pinto that he raced in NHRA's AA/Modified Compact class with great success.
That car weighed 2,350 pounds (with driver) and ran mid-nines at about 135mph, consistently, and won a lot of Modified Eliminator races.
It was a 120 cubic inch motor on gasoline with no intercooler and no water/alky injection. That would indicate about 475 horsepower, or almost 4 horsepower per cubic inch. A 426 hemi making that kind of power per cubic inch, would generate about 1,650 horsepower, so it got MY attention.
It was a draw-thru setup with the stock-type, 2-valve 1971 Pinto motor (the German one) hooked to a Doug Nash 5-speed. It inspired a few copy-cat cars with similar drivetrains... and on built by Buch Ball of Washington (state) ran well enough to grab the NHRA national record. OHIO George Montgomery also built one... all draw-thru cars.
I wouldn't want one, but apparently, they CAN be fast...
