Porsche 964 - 200kg challenge
#106
I have been following your project from the start. Impressive! Thanks for sharing your experiences.
However, ... this episode really hurt ... luckily I followed your advice and had been sitting down while watching ;-) I am curious how you will make the rear fender fit and what kind of wheels (and dimensions) you will be running.
Keep it up!

I have a set of BBS E28 that I used before and that I plan to widen in the back and use as they are in the front.
I’m thinking to go 235 front and then 295 in the back. Happy to take input on that!

I look forward to your next vids!

BBS E28 are great (as are E88 or LeMans)! However, I am no expert and there many people out there who can answer set-up questions much better (Manthey Racing for instance). I am using 9x17 255/40/17 and 8x17 225/45/17 on CUP1 with PS2 for daily use and on CUP2 with Michelin CUP2 for track use. If you want to go for 235 on the front you probably have to modify the front fender as well.
I‘ve been using Trofeo recently and they are really nice. I had the CUP2 just before and they are in my opinion almost as good, but has the benefit of lasting longer. I’m taking my other car to the track this weekend and I’ll try the 888 for the first time ;-)

Here’s the next piece. It went a bit bananas there for a while with the body seam welding, but in the end I’m happy.
If Geoffrey reads this, thanks for the inspiration!

Ive watched all the 200 kg challenge videos and he is a very impressive young man and Porsche owner IMO - the seam welding segment was very cool -
I started on my '91 964 coupe (73,000 miles) with the driver and passenger floors sound deadening removal after learning about the excessive padding on RL (what a positive difference to have your feet on the floor of the chassis (I covered the driver side with very thin rubber matting from Lowes- after several more months of ownership and as recent as last week I started on the rear floors, and then could not stand knowing I had any of the stock padding including the heavy black tar like glue against my chassis - Ive now completed removing everything except the areas between my front seats, the door sill areas, and the seat back area just below the rear shelf.
Estimated weight saving about 25 lbs total - was fortunate that very carefully using a small metal paint scraper accomplished removal down to the chassis, with some limited use of Purple Power degreaser in some areas.
After this sound deadening removal and the removal of the AB snorkel, my 964 is so much more enjoyable to drive. Previous owner already swapped for RS door cards, a stripped out Frunk, Cup Car brake duct openings, Prototipo Steering wheel. I also removed the radio.
I plan someday to do the RS carpet kit at least in the rear section (but right now enjoying the rawness of the interior) removal of the blower motor and maybe the AC unit.

Now drill that airbox!

I have just watched it on youtube... let me use the words of Chris Harris - "... J U S T M E GA !!!!!"
Please keep the videos coming - I love it!
Looking forward to the final result in weight and power/power distribution,
Greetz Tim

Jonte,
Simply amazing work! You are inspiring me of where to go with my next project and can't wait to learn more about the ECU solution. You answered many questions I have about using the GT3 intake system. I don't recall if your heads are stock or if they were ported for better breathing.

That was a great video. For some reason, I assumed GT3 intakes had to be used with ITBs.
Sign me up if you make extra lower intakes.
What ECU are you using?

One issue to consider, as I just talked to Colin Belton at 9m a of it last night, is that the reason he hasn’t produced an aluminum intake stack is that the plastic is needed to insulate the injectors etc from the heat of the heads. However like many carburetors you may be able to have an insulator sandwiched between the head and the stack. Just a thought and I have no personal experience with this so ....
I love the intake but If I were going to all the trouble of
making an intake from scratch I would consider transitioning the more diameter change throughout the runners rather than the relatively sudden transition happening just in the stack where you really want to keep the velocity high. In fact I wonder if there is any reason not to just make the intake runners and the stacks as a single piece.

This is my favourite video to date. Wow. The manifold is next level! Love it. I just wish I got one of these for my car.
Awesome.
Can’t wait to see the final weight of the assembled car. Do you have any idea / hope where it will come out?
I am thinking mine will be about 1,150kg’s once complete. But maybe a little lighter.

Definitely one of the best videos yet and a must watch for anyone considering a gt3 intake. Jonte you must be an engineer?
I imagine you are keeping the intake ports in the head at stock dimensions VS enlarging to 993 RS spec (3mm more I believe)?
