Hurricane 270 race flash with stock muffler flash (600 mile review )

[Macheater]

Tested it bone stock to get a baseline, and it was only able to pull 186 HP.

Tested it with the tune bundle in, and the 225 tune pulled 203HP, and the 240 and 270 pulled only 213HP.

Many boost leaks, Stock BOV was junk(leaked like crazy), and had exhaust leaks as well...she just couldn’t make/or hold the boost to make the power.

Took care of all the boost leaks and exhaust leaks and put in a Turbosmart BOV, with the 3 Bar map sensor, and she pulled a lil over 206 HP stock.

And then when tested with the tunes, the 225 and 270 tunes exceeded their HP, and the 240 tune was dead on.

Imo..from what we saw with the Dyno...substantial gains to be had with the 3 bar map sensor and Turbosmart BOV...at least in my situation.

Where did you do your dyno testing at?

Where did you do your dyno testing at?

Tommcat Performance in Chicopee, Mass. Very knowledgeable guys!

 

[Macheater]

What type of dyno?

 

[WinterWolf]

Dyno-Mite Land n Sea.

Straight 45 may be steep, the angles compared to a non roller clutch do not work directly. The effect an angle has on a roller vs button secondary are not the same so a 45 on a button viper vs a 45 on a roller sidewinder are not comparable

Plus the fact the Sidewinder roller clutch has a larger Dia helix which also requires less angle than the Viper or Apex model secondaries.

Great info.

Wow, that’s incredible!!! I guess stock BOV is even worse than I imagined.

It was on mine at least...others seem like the stock one is working better than mine was, so you never know??

Right on Knapp! Didnt want to see someone waste money on a helix that will never even be in the ballpark

Not sure about that!

Go ahead and try it if you think a straight 45 is going to work. Seat of the pants testing with perceived "good results" and wasted money may well be the result.
I'll rely on the over 200 track dyno pulls on my sled and dyno charts testing dozens of setups with different weight profiles, springs and helixs to get the best power to track. Still hard to beat the stock helix. Minor improvements here and there depending on the goal eith a multi angle. But theres not a magical helix out there for these sleds that's going to noticeably blow you away.

Dyno gets clutching close and then field tune to dial it in. And I prefer data backed up by timers. Just my personal preference. The whole sales pitch of "gained 4 sled lengths" etc always makes me laugh means nothing to me. In 300 ft in 4000 ft across the lake etc. Very vague way of measuring improvement .
Plenty of good products out there that work and dont need dynos to do it so I'm not saying that's the have all be all. Just seen a lot of guys bolt in setups they think will work on then they go to a local race and lose a couple tenths but could have sworn the sled was faster.
Just trying to prevent someone from wasting time and money thinking the sidewinder secondary components will directly relate to the viper secondary even remotely

 

[Fleecer]

Not sure about that!

Here is my 5 cents....
I have viper secondary with straight 45 and bolted it on my winder. It turned the same rpm as factory winder secondary with straight 35. A couple lengths slower in the midrange, but could go more than twice as far on belts.

I put stock apex helix 51/43 in viper secondary and couldn't come close to pulling that.

 

[STAIN]

Just bolting in a helix without taking into consideration the profile of your primary weight is a shooting in the dark approach at best. Make the clutches work together, not against each other.

Dumb question I'm sure. But where is the map sensor located? Is it in the front of the sled some place?

Right by the fuse box
