What makes the strongest NA RX

[kinger]

To a stock engine whats the specs for a hard running RX with just NA?

Rev speed
best clutching set up
gearing
filters yes or no
Sea level jetting

Basically how you would set up a stock engine.

Looking for top speed in the 120's on the dream meter, with no internal engine mods

Just curious.

Arent you running juice?? The best stock set up I haver personally witnessed is the ECP with stage 2 clutching. Set to stab to 10,000 and climb to 10,2-10,3.

on my 03 rx the fastest speed came at 10500 rpm. lower gearing with overdrive clutches. dalton clutching. modded stock airbox pulled higher speeds than filters. when stretched to 136 with ripsaw pulled 116mph on radar. this sled also had reverse.

top speed

i pulled my highest top speeds at 10500 rpm. and allso the best drag wins at this rpm as well. all with dalton arms helx and springs and have seen speeds of over 140 mph on the dream meter on those long pulls down the lakes (6-7 miles +) .

Back from the dead,

Stock gearing or go down to 23T?
Overdrive clutches works
10,500 rpm

This get you to a radar speed of 115-118 mph?

Mine right now off the nitrous runs 96.5 mph didn't have a long enough stretch to get it on the nitrous but contemplating removing it just because I dont have enough people want to race me any more and so I would like the extra oomph in the trails and instead of revving at 9900. Thanks!

I'm pretty well stock except for 23T, Hauck launching ramps (from my grass kit) and 244 1.187" studs and I run 118-121 on spedo all day long. rpms jump to 10700-10900 and fall back to 10500-10700 depending on temp and snow conditions. Also Im not doing the 5-7 mile pulls like some Im running around 1/2 mile. good luck.

kinger I got 121 mph out of my backup 05 this weekend on the plowed road going from Bergland into White Pine. I am running set of Jerry Hauck machined primary Sheaves with heel clicker II. Motor is stock, Front end is off the dead RApex (Simmons Skis, Ohlins and 13mm sway bar) and I just rebuilt the rear skid a week ago due to broken front arm and replaced all of the rear axle and bogie wheels because the bearings were bad and cannot be replaced on those chinsey soliud plastic wheels. this was also after I lowered the limeter strap to the 3rd hole from the tightest.

That is what I am hoping for 125 on the dream meter and I would be happy man.

23T gear better then 22T?

you could always write it in with a sharpie thats a lot cheaper.
