964 Supercharged.....almost done

[PeteyPorscho]

We've been working on this in the shop for a little while

Finally seeing the light at the end of the tunnel

Ep9 autosport is making our headers

Anyone have experience with the tpc supercharger kits?

We're going with bigger injectors and possibly modifying the tune.

We aren't going over the top

I'd be happy to make 300hp out of the kit that says 355 hp

Here's a few pictures of cars we're doing. Comment below

I don't have experience with TPC, but have had experience with that particular supercharger on other vehicles. It is a must to have an intercooler. Blowers produce tremendous heat, especially one that small.

Even with a water to air intercooler I had on another vehicle, it lost power the longer the vehicle ran due to heat saturation.

I'd run the absolute largest intercooler you can fit if not using TPC's version to keep the engine happy.

I bet that motor will be fun down low with instant boost.

Good luck, hope to see this project through and the results.

Nice project.

I strongly agree with Tippy. Not many people talk about the increased temps with superchargers. Even in a low boost supercharger you can get intake temps above 200F. My data point comes from using a whipple twin-screw. Even at low throttle position, twin screws compress air which heats it up. So even driving gingerly you get high intake temps. The three ways to mitigate are air/air, air/water intercoolers or water/methanol injection.

I am playing now with water and water/meth injection but it uses a lot of fluid and is fairly active. I control it with the ECU so that above 124F it sprays until the air inlet temp reads below 124F. I picked that number as kind of a compromise so nothing sacred about it. I still end up using quite a bit of water so it is not practical for long trips.

The next experiment will be an air/water intercooler as I have no room in the engine bay for a reasonable air/air. The problem now is where to stick the radiator since most available fender space is used to have a working AC for Florida temps.

Best is that vancouver doesn't get overly hot.. but I understand what you mean

This kit was the non intercooler kit.. so we should definitely try to incorporate some type of water injection to keep things cool..

Last thing we need is a motor melting after a full rebuild

I do appreciate the education though.. I didn't think about temps

If not running any intercooling of any kind, E85 is great at cooling things down if you have access to it.

Petey, sorry a little off topic - how did you get that case so clean and shiny ? Is it one of those new cases from Porsche ?

Looks great.

Looks great.

Looks like paint, if you look at the over spray on things like studs, fan straps etc.

I hope you get more than 300, because that is easily obtained with bolt-on NA stuff...

[PeteKz]

...but not with the low end torque that a s/c provides.

Looks like what my vapor honing machine does. Foundry fresh.

That's a far more scary proposition than paint. I hope for that customer sake that is not the case....

Done correctly it’s not an issue. That being said I’ve seen some blasted cases without new piston squirters and that is an issue.

think you could post a picture of the crank pulley
