Q&A

wow, so fast and planted
what's the spec ?

38D

For reference, in my 1:58.0 fast lap I leave oak tree 2mph faster* (49 vs 47) but am 8mph slower at the end of the VIR back straight. That’s some serious power!

*Jan is faster in ever other turn, typically by 2-3mph, but 7-10mph in T3, 10 and 17a. That’s why he’s the pro

4.25 liter with a 981 GT4 or 718 GT4 engine as base ?

J_Rizzo_12

It's a 981 block.

Jesus thats insane. Amazing how much of a difference that Demans motor makes, even with the power kit on my 981 from Dundon its making about 404ish HP.
