Clutching for PAR head

[IDAHO HOT SHOT]

Just bought the 13.5 PAR head for my 11 Pro. I pull 8100-8150 with 10-62 weights now. Does the head make enough diff to go to 10-64's? I', sure this info is in another thread somewhere, but the search is a pain in the arss.

CLUTCHING

Throw the head in garbage and buy a turbo... I installed the head never had any horse power gain and hit DET all the way down the trail.

You and your turbo...................................

had better luck with the slp stage 3 with power commander except for the v force reeds you can through them in garbage with the head

i know a guy that had similar results. had to put av gas in to make it not det and the head was for the elevation he was at........

Very interesting. I have had zero issues on my 2013 Pro w/ the PAR combo.
Did you guys buy these new from PAR and have them set up for the elevations you ride??

Give Brad at PAR a call. He sold me the combo w/ can, MDS clutching and head for my 2013 Pro and it was almost spot on.

How much did you mess with clutching? We know now that the pro ecu sees rpm RISE as well as just rpm. You will det if rpm goes up to fast. Also, your digital tach is to slow to show if you overrev fast.

Not going to doubt your particular experience, but PAR sold a ton of those heads for the pro. Lots of people recomended it.

Yes I have one. No more det than stock and a woke the sled up.

you may be able to pull a little more weight the head works good you can tell if you ride a stocker you will notice it in the tight tree stuff

BUT i had to run 2 gallons of race to keep it from DET from 5500'-7500'
(13.6 domes) and yes it would DET at 7000'
the dealer checked my sled and it had DET 29 frigging times haha
with 2 gal. i had no issues even on the trail out or in

so... head works good but.. may need race fuel ??????
2cents

I think most 91 octane is more like, 87-88, so the extra 2 gal of ave or race fuel makes it about 91. And when we go race gnc or enduro cross in the stats the 91 there is very bad prob 85 octane. Just my 2 cents
