Superflare Billet V Stacks GSXR 600

(patented)

The EC997 dyno chart is in True HPtm scale.

To get dynojet HP, multiply True x 1.15 - to get Superflow HP, multiply x 1.18, to get Fuchs HP - Oh forget it! They all have the real HP number and then they inflate it so it reads higher on their dyno - expecting that they will sell more dynos if they make their dyno read higher than the other company's dyno. It so sad that some top 100 dealerships actually buy a dyno because it inflates HP more than another......
Me, being the marketing wizard that I am .... (not! :-) decided to start out telling the honest truth, years ago.
True HPtm is the actual amount of HP really delivered to the rear wheel.

It's not "dyno loading specific", it's not "apparent only on a dyno hp", it's not "only there under inertia loading" - It's real power, measured against a real, lifelike, "load" - as the bike experiences in the real world -

At least 10% of the dyno buying facilities in the USA have decided to go with honesty and real HP - using the EC997 Dyne systems as used at the best of tuning centers -
The Factory Pro Tuning Centers

You'll see them in F-USA - you'll see them as the winners of the biggest classes in WERA National Championships, you'll see them as multiple World Suzuki Cup Champions, you'll see them as the 2004 National USA Endurance Champions, too - They don't get fooled - they all use Factory Pro EC997 dyne systems for True HP.

Anyway.... the stacks.......
OK - the above dyno chart shows the power difference between a bike with stock exhaust and stock air filter, tuned to make best power with the TEKA SFI Programmer (no pc3!) and we changed just the stacks and retrimmed the fuel with the TEKA.
You can see on the 2 lower red and blue lines that we didn't change the mixture very much.

The original stock Suzuki "short" stacks have the same problem as the Graves stacks on the fi R6's - there's simply restricted airflow at high rpms to make optimal power at very high rpms - insufficient radius / flare. Interestingly, I think that they would only work well on a flow bench if you didn't duplicate the actual intake velocity and used low, typical flowbench velocities -

The results are typical for our patented v stacks - The Factory Pro stacks are shaped  better than stock, so they propagate and recover the intake wave more efficiently, as shown by the "meatier" upper midrange and make more power at redline, due to the improved flow rates at higher velocities.

Actually, as it turns out, the "short" stock Suzuki stacks, after the radius problems were worked out, were "too short".
They use a shorter stack to bias the high rpm power, with poor wave rates - We used better wave rates and then we could lengthen the intake tract length to get more midrange power. We ended up with better top (flow related) and better upper mid (wave rate).

Shifting improvements

Stage 1

The Shift Spring


You will miss fewer shifts, shift even quicker and help prevent shift fork damage caused by missed shifts.

Suggest both the spring and the Star.

The star and spring are located behind the clutch basket. 1-2 hours to install.

S70-Shift STAR    $139.95

Factory Pro's famous Shift Star

Stage 2
(after you have the F-Pro arm and spring)

GSXR Shift STAR

The gsxr 600 can get the same benefits that the 2020 gsxrs can get with the Factory Pro Shift STAR.

The "Paddle Shifter" for your foot -
The 01 and 02 1000's (and 750's and 600's!) need help in shifting. Track tests report that 2nd gear had a repeatable ability to pop out into "neutral" under hard acceleration.
Aside from that, the late style gsxr shift action is very flat feeling and gives very little tactile feedback as to confidence that it's really in gear or not. I hate it when you shift and you can hear the shift mechanism sort of  lazily "kathwaka" into it's final gear location. I like a confident, proper "snick"!
They had it so close to "almost good"  in 99 - I'm not sure why they changed it for the "non-better".... Oh well - After redesigning and testing and redesigning and testing, and redesigning and testing...... I now see how easy it is to get it wrong, though.
We have a new detent "star" with a copyrighted profile (yep, the "science failed, so, it's artwork - so it's copyrighted) that includes a particular combination of compound arcs and radii that produces a shift action that makes it almost impossible to miss a shift ("almost" is the key word here!), especially 2nd gear. At least, if you miss 2nd, now, you will be REALLY surprised - cause it's now such a rare occurrence.
Downshifting confidence is 100% easier and better, also. Maybe that's just as important as not missing upshifts!
I'm happy with the "star" and couldn't possibly change it for the better and I figure that it will take Suzuki 2 years to copy it!

New manufacture:
Beautifully machined on 8 Axis CNC machinery, machined from solid Cro-Mo steel bar stock, heat treated, a complex radii, beautiful part.

Note:
The stock detent star seems to loosen up the bolt that holds it on, causing missed shifts - esp. 2nd gear. Your Suzuki dealer will probably warranty it (if possible) and retighten it. It's a perfect time to install our S70 Detent Star, which fits tighter and is less likely to loosen up again, like the stock star.

These are THE COVERS.

So good - they are patented!
NOT a simple, "knocked off" copy machined from billet cover - these are the covers responsible for saving more engines from destruction and kept more racetracks cleaner than, perhaps, all other aftermarket "billet" covers combined!
For Race or Street use. Absolutely the strongest cover you can buy. Highest strength / weight ratio available! Maximum protection at ~1 pound of additional weight!
More cover thickness than stock on both RH and LH side covers.
Visible on LH and RH side - Can be show polished to a mirror finish!
Includes: Integral SLIDERS, Billet Covers, gaskets and replacement stainless steel allen screws.
SLIDERS available separately for replacement!
