tempa flow install on mtn viper 700 slp pipes

[yamisledhead]

Just installed SLP ceramic pipes, v-force reed's, peak performance head's cut to 22cc elevation I am at is 1750. I am running the jetting according to SLP spec's 165main 3.5 on the needle 47.5 pilot and 1-3/4 turns out on fuel screw. Took it out today and it was -20c plug's were a nice light brown. Right where I'd like to see it, I was wondering If someone has experience running tempa flow.

i think they are a bad idea. they are a good for a while but when you slow down the heat of the sled gives off and the tempa-flow leans out the motor untill you take off and hit cold air across it again then it richens it up again. but the problem is how many time do you come to a stop on the trail and then take off. each time it gives it a slight lean condition.

That is true, I have looked at the installation instruction's for this and I would think it is quite crutial where the tempa-flow is draw it's air from. You will see different install's from guy's drawing air from inside the air box, to venting it right behind the air box just infront of the steering column. I know I am leary of the temp fluctuation's that go to this.

I've ran one for years on my 02 with no problems. Plugs always look good. I ride 99% trails. I am always careful about starting after stopping on the trail. I believe the venting for the Viper is in the air box. I talked to Barry Holtzman when I was installing mine and he was very helpful and answered all my questions.

I agree with Chasx7, wouldn't go without one on a triple piped Viper as it gives you some adjustability when temps, humidity, etc. vary and sure helps out with gas mileage too.

You need to vent it to outside of the hood somewhere. Mine (atacc, not tempa flow, but same concept/ inventor) is vented to underneath my bar pad. It's not difficult and not prone to drawing in hot, humid air either.

I actually seem to have more of an issue consuming too much oil/ too rich, if any issue exists at all. But all in all it's the closest thing to fuel injection you can get to with the triples.

Yamisledhead:

I did about the same thing as you this year... slp trips, speedwerx performance head, I'm the same on jetting except someone on here (i think mopar1rules) highly recommends setting your needle at 4 which is the notch below the middle with both washers on below.

I just got my tempaflow installed & have about 20 miles with it. It is incredible. I am very concerned about the lean-out condition caused when the sled sits and heats up the airbox which I don't like b/c very often everyone jumps on and takes off at WOT. Can't do that, must be careful. The way I see it is Risk & Reward... it's a huge risk - you can certainly blow your motor but the rewards are also huge - performance & mpg

It was suggested that it might help if the air inlet was outside the airbox in the cold air - this is not true. The actual tempaflow device itself heats up and takes like 90 seconds to re-adjust once it starts getting cold air. I've heard of guys installing the device outside of the motor compartment, but don't know any details of that setup. I've also heard a mention of a by-pass type mod that eliminates this risk but no details where given on that setup either. If anyone has input on this I'm very curious.

Another note too: SRXRules instructions show the vacuum tube coming off the tempaflow on the side and thru the airbox openings to below the shelf where it hooks up to the existing carb tubing. According to the instructions and others, it should point downward and there should be no place where water (due to condensation) can collect and interfere with the vacuum... needs to drain to the carbs completely.

Super Sled:

I don't think that is correct - I've spent a lot of time researching here and with the instructions. Your air inlet (end opposite the screw) is supposed to take air from the same place as the vacuum tubes did - which on a viper is under the shelf in the air box. I have a 90 elbow and drilled a hole on mine with a short tube down. This maybe why your's runs on the rich side. Mine is dead on perfect.
