Re: 450 SBC Preliminary Dyno Results
Total of 24 pulls in 2 days.
Chased my tail most of the day trying to tune the homemade 1250 HP(single) on the sheetmetal intake with a tee pee top.
Guess there is something to this tuned intake runner length stuff
The sheetmetal intake is within .25" of the 4th harmonic for this combination.
Best pull was 915 HP @ 7400 RPM and 713.8 lb-ft @ 6000 RPM
That was with Royal Purple XPR 5W20 oil and Q16.
With the break in Joe Gibbs oil it was 911 HP / 702 lb-ft
Didn't get any video, but "pissed off small block" describes it pretty darn well.
Didn't get test the 2x1000 HP combination for several reason. We'll have to save that for another day.
All in all I'm very pleased with the results.
Naturally Aspriated 450 SBC - 915 HP / 714 lb-ft
1.33 - 60', 6.02 @ 116.7 MPH - 1/8th
