You’re dumb as fuck and got owned hard I thought of you when I first saw the add for this sled I am looking at. Sled has 3 tunes available, 230, 270, and 295hp. Right from the ad: "NO clutch changes required between tunes" 1 Quote Link to comment Share on other sites More sharing options...

The limit can be many things but can usually be boiled down to a restriction in flow in the motor , limits of the valve springs or limits in flow of the turbo. These things are usually well beyond pump gas tunes Quote Link to comment Share on other sites More sharing options...

The valve springs are the major factor for rpm limits .....it’s a bit murky depending on power levels but something well short of 9k for stock valve springs and 20lbs of boost or less. This is all assuming a more free flowing exhaust. A constrictive exhaust holds heat in the motor and then everything gets tighter limit wise Edited February 13, 2021 by f7ben Quote Link to comment Share on other sites More sharing options...

I haven’t run any....the first one if the season is this weekend but I think it’s canceled as it’s supposed to be -33f tonight and only -11f for a high tomorrow. My sled only has enough gear in it for 120 or so mph no either way. I’d be out of gear in 750’ or less on ice. 1 Quote Link to comment Share on other sites More sharing options...

It also does cool shit like calculate elevation change to fractions of an inch and density altitude etc. What sealed it for me is the video overlay stuff they ironed out in the app. Google some dragy vids. They did a decent job Edited February 13, 2021 by f7ben Quote Link to comment Share on other sites More sharing options...

Pro Mod Hurricane Hemi Engine $7,499.00 USD The Hurricane Hemi Engine has proven to add 20 HP with a significant increase in torque over the Hurricane Pro mod engine. This engine combination is designed to maximize the efficiency while using the stock 998 turbo to meet race rules. The Hurricane Hemi Pro mod Engine includes CNC ported head, aggressive intake and exhaust cams, double valve springs, Hurricane Valve shim retaining kit on exhaust cam, Hemi combustion chamber, custom Hurricane – CP pistons, Carrillo Rods, custom ARP head studs, double O-ring, head gasket, and much more! We are confident that when you need the most power to win while meeting all sanctioned rules, the Hurricane Hemi Pro mod Engine will deliver.

In a full race gas setup on stock turbo that motor is gonna make a difference. On 93 octane it wouldn’t matter a whole lot. Maybe a little more power just do to better flow but who knows 1 Quote Link to comment Share on other sites More sharing options...
