I'm waiting on Sul
That's what I'm waiting for. Cause I know he's tried all these popular carbs. Further, he's not doing anything else but the carb. So it will be a better comparison and therefore opinion. No offense to Scott.

Scott... awesome numbers... but alot of work into those as well...
 
any comment on the PSI carb versus the pegasus fuel injection module??? I mean for the $1300 carb, is it not just worth it for the $2000 FI kit?

Yeah, back up your claims bro. We've all been curious about these carbs for a while. 10% is a big claim, and for 1300 bucks 10% can come a bunch of different ways...who else on here was doing a swap???
Hey, don't get your nose out of joint...



j/k Sounds like your doing OK after the surgery :up:


The expense makes it a tuff sell, while I'm interested, so much to do before I could "use" its potential.

Interesting??
Those numbers look good.... but i don't see a lot of info.
I'd like to know,, the Elevation, Temp, Humidity, Barometric Pressure, Air/Fuel Mixture.
Was there a correction factor to Sea Level used to produce the numbers? Enquiring minds want to know!!! :up:

Well i am from St. Louis Missouri. I dont know any information on my Barometric Pressure or anything. But it was about 80 degrees that day. I would almost guarantee you that you will get the improvements that i got where ever you are.

But the number one problem with all of that... is that is ONE HECK of a list of mods.

Then I must ask... was the PSI the last mod. As in did you have these other mods on the bike with the S&S G then add the PSI? And what's to say the XXX carb wouldn't produce the same 10% increase???

The super G was clearly out of tune or there was some tire slippage on two of those dyno graphs. Were the dyno runs done on the same day with similar conditions? There is no correction factor on these dyno sheets. You listed you had 151 horse on another post. Is the top dyno run yours?

If you look at the dyno sheets with the shading that was from a G with the T Jet and we ran it then swaped it out the same day, actually about a hour later and tuned it and ran it!! That is no joke or bs. Its the truth!!!! The g carb was tunned!!!!!

None of these are my bike with the 151 hp. These are customers bikes we did. The Top Dyno sheet is one we did for a customer, then the bottom two are the same bike just one is shaded to tell you all the gain you get this is a STOCK 117 with no motor mods!!!! JUST A CARB!!!! We here in St. Louis are all about having the fastest shit!!!

Wow, those #'s are impressive. Can you post your dyno results?

OUCH, pissed sounds pissed!
I'm not second guessing, but the bottom run indicates an additional 20 hp or an 18% gain, and an additional 8 ft lbs or 10% gain. Pretty strong for nothing more than a bolt on carb. But then again, the PSI site say's up to 22 hp!? These carbs just may be the shit.
