That's going to be vicious. Do you think it will handle more like a 911? Really enjoying your journey.

Hopefully not fortunately the engine is in the middle so adding weight to the middle of the car shouldn’t change things much, we’ll see. I’m sure the additional power will change just about everything though, in the past throttle control rarely came into play, I was either off throttle or on full throttle. The car never had enough power to need a light foot. Hopefully the 315 series Hoosier will help, the open diff on the other hand...

Perhaps it's time for an OS Giken LSD..?

Where did you get the radiator for the frunk? I need to upgrade mine to something like that one

Here’s a link to the rad, you’ll need to cut a huge hole on the front of the trunk and bumper and make a hood vent (I made one out of aluminum but you could buy something off amazon I’m sure). Plumbing this thing up is no proving to be very difficult. The Boxster has two coolant hoses going forward and two back so you need to make some complex manifolds to make it work. Still a work in progress.

Awesome! Thanks a bunch! I'm using a toyota corolla radiator with an electric water pump right now but the radiator isn't up to the demand I'm producing with my rally boxster. I have to say I think your boxster build is the most intriguing build ever. My hat is off to you. Keep it up, it's very entertaining.

This is really sweet. Badass looking car, I'm taking notes.

Some random quations: What's the offset on your rear wheels? Any clearance issues? And I dig your frunk mount radiator. That was the origional plan on mine, but we ended up going a different route. I'm also very much considering s̶t̶e̶a̶l̶i̶n̶g̶ borrowing your widebody design.


One of these days, we need to meet up at VIR.

Thanks! The rear wheels are 12”s wide with the hub right in the middle of the wheel. I don’t have fitment issues but the fenders are of course not factory. The front is 8”s wider which I accomplished by extending the front suspension (I didn’t change the offset of the wheels). The rear fenders were actually really easy to make I used .125” think aluminum (super super thin). It can’t even support itself unless it’s bolted down, but once’s secured its rock solid.

Do you really need the fans for the middle radiator? I take it you still got the fans for the outer rads, then the speed will likely give enough flow for the middle one. It´s obviously not a road car that will be sitting in slow traffic, so I´d suggest you get rid of that extra weight!

Good point..I’ve removed the fans from the outer rads for this reason. I probably don’t need any fans and could just place a fan in front of the rad in the paddock once I come in if I want the car to run and cool down.

Wow super similar widebody design that he’s working on right now. That’s a dream build. Definitely working with a different budget...

Progress continues, I'll post later on the hardware progress. In the meantime I've tackled the gauge problem. The stand alone computer won't be able to talk to the Porsche gauges so I made a digital dash using realdash and an iPad that sits behind the factory cluster. Checkout the youtube link below of it in action

Can you provide some information on how you mounted it in the car. Also did you try to get the VEMS to communicate with cluster or told that it wouldn't from company?

[Racer Boy]

Wow, that's awesome!

This is such an awesome build, do you ever bring it to c&c?

Thanks! Pre-covid I was normally there with my 911 but I plan on bringing the Boxster this summer (maybe on a trailer, I’ll be that guy). Let me know when you’re going on all I’ll meet you there if I’m not on baby duty (or if I am on baby duty and have finally have replaced my non-baby friendly straight pipes on the 911).

More turbo goodies are arriving, all the fuel system parts are in but I'm still waiting on the Turbos to arrive (next week hopefully) and the final intercooler is backordered so who knows. Last night I got the coolant system roughed in and cut some more of the body panels that hide underneath the aluminum widebody (this also makes room for the intercoolers that will sit just in front of the rear wheels). I have cut out a tremendous amount of steel so far, I'm hoping with the V8 and the twin turbo system (which is probably 130lbs) I'll still be under 2500lbs. At a minimum the weight balance is going to off. This weekend I'll throw the fuel system in, button up the coolant system and build at least one new wheel well to accommodate the 8" wider body and new 12" wide rear wheels, I'm going to cut out all the steel from the wheel wells, it'll all be aluminum. I have a feeling I'm going to end up with just the frame rails and a tubular steel rear frame here soon. more to come later
