Can you give more information on how these two engines compare/tested from strictly a drag race 132' comparison?
Your 35+21 says it is the ultimate, the fastest, but the Kangaroo says it's shown to run 1.5-1.6, some of the lowest times I have heard
Also, what pipe set do you suggest for these two drag mod engines. Thank You

This is the ultimate engine to go 132 FT the fastest. Offers the most torque of any .21 engine.

This engine has insane bottom end. This engine has been shown with the right car, pipe and driver to run in the 1.5-1.6 second range to 132 feet.
Hi. Both of these engines will run similar times. The 35+21 needs to be geared a little shorter, as it comes on hard at half track to the end. The R1 comes on hard to half track, and then flattens out a little compared to the 35+21. Sean uses a Mac 1120 boat pipe with both engines.
The 35+21 has more peak torque, and HP than the R1. It is just harder to harness the 35+21 power due to peaks happening higher in the powerband compared to the R1.
The comparable cost increase on the R1 vs 35+21 is due to the R1 coming with a steel rear bearing. The 35+21 comes with a ceramic that I can sell as spare parts.
