67GTA replied to the thread Boss Axle (No) Vent.Another note on this - I’m using the port circled in red on the watts link cover in lieu of the one on top. Cortex v1 cover didn’t have the top vent port, which was the location on the stock Boss cover that was tough to get low enough to not... (see full post)-

67GTA replied to the thread Boss Axle (No) Vent.Here’s a screenshot of the configuration. The order number is on there too, so Brendan may be able to replicate from their records as well.I won’t be around the car for a couple weeks, but will try and get a some reference pics in early July.

Mjschneidy replied to the thread Advice on setup for street and track!.Thanks guys for sharing the knowledge, you've short cut my next steps to sorting out my M1 HP. Was in the process of looking at linear rate springs both production offerings and aftermarket.Purpose for our car is exactly the same, make it a... (see full post)
flyboy55 replied to the thread Comp Cam limiters or lockout blocks.I get the premise of timing the advance or retard for different power. But, I chose the 127500s for my new rebuild. I believe with the lift and duration numbers, Comp says to use limiter. I thought I read somewhere that the Ford Performance... (see full post)
steveespo replied to the thread S550 Heel-toe struggles.Are they as good as the DarkHorse or DHR? No. But are they good and better than me twisting my right leg and ankle around while braking for Turn 7 at Sebring. Yes very much so. And if you watch the video you see me trick the system in Turn 10... (see full post)
Mike_FL replied to the thread S550 Heel-toe struggles.The Autoblip is one of my favorite modifications on my S197. I did think about getting the Xineering blip module and they are based a couple of miles away and could have installed it but I decided against it. The need for an android phone or... (see full post)
honeybadger replied to the thread Comp Cam limiters or lockout blocks.this echos my experience. To actually make the most power, you need to otpimize all of the pieces...have to get the right cam profile and the right cam timing dialed in with the tune....and that can mean adjusting the came timing a few times...

Bedouin replied to the thread S550 Heel-toe struggles...and it’s an invaluable skill if you’re driving a manual car/truck down an icy mountain pass & can’t break traction with a mismatched downshift. (see full post)- stevbd replied to the thread S550 Heel-toe struggles.Fair points but are the aftermarket modules really as seamless and dialed in as the modern oem auto blip features? I don’t have any personal experience but how do the modules know when you want a big blip versus a small brush of the gas etc? I... (see full post)
mavisky replied to the thread S550 mavisky's "LOUDCAR".It scrapes the parking lot all the time, it's not the flattest parking lot ever built. We run down at the Echo Park Speedway parking lot (formerly Atlanta Speedway) on the south side of town. Unfortunately this is the only area we have to race... (see full post)-

67GTA replied to the thread Boss Axle (No) Vent.I’ve been running the Bob’s kit since 2019. For such a simple concept, it took some trial and error to get it dialed in. The only physical mod I made to eliminate any contact with the axle was to open up the half-moon shaped cut on the one... (see full post)

steveespo replied to the thread S550 Heel-toe struggles.When you watch Cayman GT4 and 991GT3s walk away on the ups and downshifts, you can understand the need to put the pride away and use the available tech to compete. All the props for those who can do the "heel/toe dance". But I will say this... (see full post)
S550AZ replied to the thread S197 2011 RTR #041.@Bill Pemberton I am trying out the new Firestone Firehawk Indy 500 V2 by Bridgestone. My tire guy said a few guys have started running them on their street cars and the tires are holding up. For the track, they get a little greasy when they get... (see full post)
GAR944 replied to the thread S550 Heel-toe struggles.I've been watching this thread with interest as to me it appears to be an American thing to use "artificial" heel/toe addons. I've never known they were even a thing till this forum. My guess was the propensity for automatic transmissions and big... (see full post)- CarSalesman replied to the thread Comp Cam limiters or lockout blocks.Depends on which cam you choose. I just installed the #500 cam which requires springs and limiters. It’s a lot more lift than stock so when Comp says phaser limiters are required I believe them. Sounds nasty see my build thread. I have had it... (see full post)
- CarSalesman replied to the thread S197 FR500S031.Welcome to the FR500S club. See my posts. Sachs will rebuild the coil overs for $400 each.I haven’t had any trouble with engine overheating. These cars were raced in some hot climate. If you have an overheat issue I would find the source... (see full post)
- cjatrains replied to the thread Advice on setup for street and track!.Spot On @TeeLew ... You're numbers for the rear are extremely close to what I was able to research on the forums, Factory Mach 1 HP rear coil spring rate = 742 #/inch, Front Mach 1 HP coil spring original equipment = 211 #/inch. We had... (see full post)
- TeeLew replied to the thread Advice on setup for street and track!.For reference, I think @cjatrains has a front spring rate of about 310 #/in once all-in with the spring rubber. That probably ramps to 330 or so as it compresses, because that's what spring rubbers do. These are guesses, but it will give an idea... (see full post)
Bill Pemberton replied to the thread S550 Heel-toe struggles.Still prefer heel and toe, it is a tango that has your shifter as your dance partner and I always felt learning it well was what helped me keep my transmissions alive. My Mach 1 had a factory blip shift and I never really cared for it. Yes I am... (see full post)
