Yeah I think I get it, over revving wouldn't yield speed gains in every scenario it all depends on the setup and the actual hp being outputted at that rpm. Nothing can be simple right? Dang...

u can attain higher r.p.m. with clutches at max ratio if conditions are favorable. reduced resistance will allow this even though engine is not at r.p.m. where it is at peak power.

like to see it. those mechanical speedos are not necessarily that accurate.
corrrect, They are not accurate on any pro-action sled. With the top end number he is posting, either sled I mentioned would exceed that if properly tuned
I was neck and neck with an RX-1 with after market air intake and exhaust, not sure how that race normally runs, but I did beat him 3 out of 5. Never heard of SRX 600 or SXR 700 having that great of top end, although speedometer readings vary a lot from GPS so it's hard to say.

TIGHT,IN YOUR TRACK UP SO THERE IS NO RATCHET AT ALL. LOSE TRACK WILL SCUFF MPH. 3:16 (yammie tony)
Yeah that could be a contributing factor, weird that it only did it with the red spring. I thought you wanted your track as loose as possible without any ratchet. If there is no ratchet with the green spring wouldn't that be ideal?
I have a similar problem with you with my mostly stock '01. Bone stock except for green secondary spring wrapped to 70 and a Dalton 52R46 helix. Haven't had a lot of ride time yet (breakdowns) but it seems to peg 8600 instantly which is a bit high. I tried the red spring wrapped to 80 and the backshifting sucked and didn't really make any difference for RPM.

TIGHT TRACK BUD. THAT LOSE THEORY CHANGED. LOSE TRACK CAN BELLOW/ SCUFF SPEED. BESIDES, VERY DANGEROUS HARD BRAKING WHEN LOSE ESPECIALLY WITH WHERE THAT COOLER IS. HAS TO be TIGHT FOR SPEED. NO RACHETING. 3:16 (yammie tony)
Sounds good Yammi. Will see what she can do on top end then!

Can you guys tell me what is the exact stock specs for a 2001 SRX clutching. Thanks.

its in the tech pages
That is 100% wrong!! 8500rpm with 1 clutch setup might yield 105mph while another clutch setup that runs 8500rpm might yield 110mph while another clutch setup that runs 8500rpms might yield more or less mph. Go to a speed run and if you can possibly get the guys to share their clutch setups ( I doubt you will though) then pay attention to their speeds on the track. Their are probably 20+ different clutch setups to get you 8500 rpms and they will all have different speeds on the track.davidgboy said:
their are a million factors that change your results also. to get 100% accurate results as far as changes go you need to have the exact same air temperature, exact same barometric pressure, exact same track conditions( prefferably glare/shaved ice) for top speed runs, engine warmed up the same, optimum temp in pipes, etc. etc. etc.
