Oh man, just came across this thread by chance while looking for a trans cooler for my GX. Tons of great writeups in here and I'm working through it bit by bit. Reading this has made me realize that you're the same guy that drives the red prelude and owned the Spoon CL7 that was featured with Larry Chen on his channel. You've had some pretty killer cars.
This thing is pretty menacing when viewed from the side with the fender vents and wing.
Saw the ISF at BRP this past December at the vtec club event and it's a very impressive build. I'd thought you hit the curb off of phil hill with how the front end looked when I saw the car at the end of the day. Crazy that the splitter digging in did that much damage. It's great seeing the progress of the rebuild through the thread though. Looking forward to how this thing does at it's next outing as a full on race car.
You can also see the CNC machined Jabroc skid material here.. the down side is replacement skid jabroc is 2500 bucks a side. Im planning of 3d scanning these so I can mill them out of a less heavy, less expensive material like delrin..
My unsolicited advice is to stick with some kind of laminate like G10/garolite or micarta, since Jabroc itself is essentially micarta made with beech veneer. A monolithic thermoplastic like delrin, HDPE, or UHMWPE--I think--would abrade away too quickly. I'm just thinking of how easy the various materials are to sand...
I'd imagine the most cost effective way would be to make yourself some molds to press glass cloth and epoxy into so you can unlock infinite skid plate mod. At that point, might as well add a layer or a couple of keblarr and add some graphite-impregnated epoxy into the mix...and you should end up with a lighter, higher-wear laminate than Jabroc. The keel of my gheenoe has just one layer of 5oz kevlar tape under 2-4 layers of 8oz glass cloth with graphited resin and has survived an awful lot more than I want to admit to, including flight lessons at 85mph on I-95, grinding all the way through the chine (which was factory blown glass) but leaving a perfect spine to rebuild from. Before I started loving that boat, I'd happily drag it through a parking lot and down some sidewalks to chuck it over a seawall or off a pedestrian bridge, rather than pay the north palm beach trailer tax to use an utterly empty parking lot at 2am. I digress.
I'd look to the airboat racing crowd for how to make laminates last longer. Stuff like Frog Spit, Fasco Super Slick, et cetera repeatedly bear the weight of the airboat while going over land at low speed--often over rocks, gravel, and asphalt just to go over the Herbert Hoover dike without cycling through the locks (some locks don't allow blowboats).
Anyway. Truly inspiring thread. I often come here for reference pics of how the 2is was put together. Keep it up.
I haven't posted in a while but there is plenty ongoing with the car, building a bunch of carbon parts. Been tracking a few times a month while I continue to refine everything and make it faster.
New Dash, gutted ALL the looms now. there is zero extraneous wiring in the name of simplicity and weight. Also figured out wiring, wheel spacing and how to reliably run after market steering wheel and paddles. (hint its NOT as easy as you think wiring and machining parts are involved.)
Car is now a few seconds faster on all tracks than it was a year ago. Still stock power with headers and tune as the only power mods.
Lots of other things done to it in here and there. on 11/11 square wheels now and the car now weighs under 3k. I'm pretty certain its the lightest ISF possibly in the world, most definitely one of the most developed for time attack.
Been working a lot on building other cars too like my full carbon Radical SR3. They are super fun, and fast, but the ISF is is a different kind of fun that makes me keep going back to develop it more after spending time in the Radical.
Since this thread is ungodly long (which is a good thing) could you publish a list of your off the shelf parts or a very brief description of the not OTS? Like headers, exhaust, aero, etc. tryna find the best for my F and obvi u use nothing but the best! Thanks a lot
