We’ve been trying our hand at recording video! Hopefully it gives viewers a glimpse into what kind of books we provide. Check out our latest video for our book, Blown Nitro Racing on a Budget: You can learn more about this book in our store!
At a local drag racing event recently, we helped one of the racers chop 0.3 seconds off his ET slip with a correct addition of a low percentage of nitro. The racecar was an early model, low compression Hemi drag car with a small 6 GPM fuel pump. It ran solid 7.6 seconds in the […]
A few weeks ago, one of the drag racers completed competition with a bracket blown alcohol 7.60 second ET setup. It was close to maxed out with a small 0.040 inch main bypass jet in his fuel injection setup. The main bypass jet is used to return excess fuel to the fuel tank. In this […]
Over a short but significant period in US Top Fuel drag racing history, the Surfers Team set record level performance. The Surfers Team was made up of owners/builders/tuners, Bob Skinner & Tom Jobe with driver/crew member, Mike Sorokin. Their nitro Chrysler (early) Hemi dragster quickly became one the sport’s best performers. Highlights of their setup […]
We found some interesting nitro stats in a recent racing history search. Art Malone was one of the frontrunners in the mid 1960’s in Top Fuel drag racing. Note the following: Engine: Early Model Hemi 398 ci Blower: Roots 6-71 @ 18% OD Fuel injection hat: Hilborn Bugcatcher (4 hole front) Fuel pump: Hilborn 12.5 […]
Jerry Gleason’s fuel injected Big Block drag race boat set the latest (at the time) APBA unblown fuel record at 130 MPH. That was done on 30% nitro (Ref. HRM, April, 1968, p. 107). Keep in mind that was with typical OEM Big Block cylinder heads and block. It was with cam lift and timing, […]
Decreased percentages of nitro richen the racing engine.
We made a full pass. Picked up 3 tenths of a second and about 7 MPH over 9% nitro. It was a rush. The engine is louder. And more radical. We are still making enough engine heat at idle to keep the oil dilution minimal. We are on our 16th pass on the same oil […]
We dropped the AFR to 3.2 The idle went up by 300 RPM over the 9% setup (with no idle adjustments).
With a small increase from 6% to 9% nitro, in preparation we dropped the AFR to from 3.7 to 3.4. As a result, we picked up a tenth of a second and about 4 MPH over 6% nitro.
