Any guesses on what my 9 SSL weighs in at without me in it? (with 2 gallons of fuel)
Removed:
Front/Rear crash beams
front engine strut bar

wheels - 17" rpf1
suspension - f2 coilovers
exhaust/intake/ic piping, etc
battery - mini battery

Sure is...I guess it being 5 years back I forgot what it actually weighed.
13.2lbs for the intercooler and all mounting hardware
18.6lb total for all piping, adel clamps, IAT sensor and Tial BOV
Sorry.
Still light though.
I don't know why people use anything but aluminum on IC piping. It's all I've EVER used and I've never had a problem with cracking. I have had problems with t-bolt clamps crushing the tube out of round though which can lead to blowing off IC pipes, particularly if you go up to 3". There are better clamps that you can use though that won't crush the tube, or you can use some 1/8" thick rings at the ends to clamp on to.

Regarding the tow strap stuff. Unless I read this wrong, you definitely want more than one bolt holding that in. The tensile strength of the bolt may be 8ksi but when being towed that bolt is being loaded in shear and shear strength is usually less than half of tensile strength for most materials. One bolt may be fine if the car still rolls straight but in a bad accident that renders the car immobile you're going to want more than one bolt or you may risk shearing it.
Its worked fine so far winching my car up on the trailer but to your point when the wheels arent rolling it puts far more stress on it. Im still skeptical that bolt will be the weak point vs the 4 bolts that hold on the crash beam but who knows.
And to bring this back around to sort of remain on topic what are folks thoughts on a lightweight front bumper beam with a tow strap connected to it? Id think an AL bumper beam would be a nono however something chromoly like even what STM offers should be strong enough.

Also, you guys talking about how heavy SS intercooler pipes are is making me want to cry. I too was annoyed that there seemed to be limited options for AL intercooler piping. I'd still be rocking the OEM setup at least for the UICP however with my intercooler I dont think it fit all that well and I blew off couplers all the time which sucked. Since then with my new piping which I've had on for a few years now I have yet to have another coupler blow off, knock on wood.
Those do look nice but I could have sworn someone was saying they were having issues with them leaking. Wiggins clamps are sweet too but $$$

I recently installed a tow strap on my car and this has me curious if its an accident waiting to happen. I specifically didnt want a hook bc I know its only a matter of time until it takes out my shin so strap seemed ideal. I ended up with a Sparco tow strap as it was cheap and seemed decent enough. Only catch is it only had one bolt hole. I drilled into the factory crash beam and installed it with a 5/8 grade 8 bolt and large washers. I understand the bolt is indeed in sheer vs tension but I'd think it should still be plenty strong no?

I've seen a fair amount of people use the HD clamps without issue. I know their older design vanjen clamps had issues with cracking.

My thoughts exactly. Honestly, I think my strap will fail prior to the bolt sheering. This is the strap I bought which as you can see if nothing special. To step up to a larger diameter bolt would mean opening up that hole more in which case I think I would be doing myself a disservice.

Thoughts on a tow strap attached to a chromoly bumper beam up front?

I trust my strap and the giant bolt holding in on.. but my crash beam still has those 10mm bolts holding it to the car LOL. Plus I'm tired of buying new straps.
You reduce a bit of weight from the metal you gotta cut from the hood
