what is the fastest rxp and how fast?

what is the fastest rxp and how fast? I know it is in the 80's range but how fast on gps exactly?

[Green Hulk]

Mine runs 82+ on GPS.
JD 1 has run 88+ same mods as me, but with nitrous.
Stickem has run 86 on nitrous as well.

[natris 785p]

just a guess but, are they getting a 6 mile incress with nitrous???

[Green Hulk]

Yes! What they do is run a huge amount of pitch on the prop. When they hit the juice they can hit max RPM's and produce big speed. When not on the juice the tall prop is a dog.

Do any of the GPRs run the juice??--like Kenny H. who went I think 88 plus at the 06 Mud Bug.

[Green Hulk]

No, they aren't running any juice unless they are hiding something from us

As a guesstimate: How does the Horsepower compare between the two types of craft........... JD's RXP fully decked out with nitrous vs the Kerry's record beast?

If I remember right, Jerry's RXP is probably in the range of 320-hp so with Nitrous, I would guess at least 60-hp more? And as a guess, I would think the GPR would be more in the range of 240- 260 hp. Am I way off base?

So is the hull making that much difference?

[Green Hulk]

Im probably about 310 HP with the B kit. Once Nils gets his dyno installed we'll know for sure.Those with my setup the bottle easily add's another 50-60 ponies.Hibdon is probably about 260 HP if i had to guess.Accleration between the fastest GPR's and RXP's is no contest. RXP's pull out ahead until we top out then the GPR's cruise on by.Yes, the hull difference makes all the difference in the world.

When is some one going to stop messin around with crappy rxp hull and do engine swap to gpr?

[Green Hulk]

hydrotoys is working on that right now. If it works out well i'll be doing the same thing.
