Considering the DeMan 4.5 L upgrade for my 991.1 GTS

I bought a high mileage 2013 C4S manual specifically for the Deman engine. I was trying to get an allocation for a GT4, but the cost for a slot and the ADM were just ridiculous. In the end I was honest with myself with what I wanted, and that was the GT engine and all its eargasmicness. So, all in I’ll probably spend a little over $100k and get a sleeper that’s way better as a daily and cost way less. Yeah, I may not get the money back if I sell it, which I don’t plan on ever doing. You can’t get near a used 718 GT4 even for less than $120k, so I think it’s a good deal.

You may not get all the money back but my thinking is there is a pretty strong demand for these DeMan built Porsches and with their proven track record it can only help increase the overall value of an older / higher mile model especially. If I could have found one I would have bought one that was already built by Deman.

Why not both?
@DeMan Motorsport and @RRRacing should collaborate on a supercharged, stroker motor.
Low compression, 4 liters, N/A power curve and throttle response. 600hp at the wheels on pump gas?

We've made over 600 to the wheels on a completely stock car with a $15k bolt on S/C kit. 93 pump gas

Nobody wants a car they have to check the methanol tank, or remember to add octane booster. That’s a compromise people make to get more power.

It's actually just 50/50 water/methanol and it's just used for an added measure of cooling. Frankly, it's not needed. We can do it without it and maybe sacrifice 10-15 whp tops (maybe none). The tank for it is HUGE and it only sprays under high RPM and peak boost. This means it will last a long time unless you're on the track. Then you will need to fill it more frequently.

That's a good question. Most of the time we transport the cars into our shop if they're long distance. Independent Porsche shops typically have very high hourly rates. Our fixed price to install the supercharger is very reasonable so even with transport it comes in lower than many of the independent quotes people receive. But yes, we do a large amount of the installs here in the shop. If you shoot me an email address i'd be glad to give you a quote any time.

Yes, all the 4.0L engines are eligible. Since it's mechanically the exact same engine the end results are the same.

We could build and use your existing headers, dyno results would help you decide if you want to sell yours and get the ones we produce or keep yours.
