Just to update:

The new Guard 5th gear is in and all is back together. Took the car on a 20 mile ride. The gear noise is not very noticeable. I certainly can here it but nothing at all to worry about. The car drives great with a large reduction in rpms!

At 3200 rpms I am at 100 MPH
At 3500 rpms I am at 110 MPH.

This will solve any rise in radiator temps on the highway. Next step is to create my heating for the car. The air conditioning works wonderful but I have no heat to help defrost the windows!

Electrical question on a 997...

I had a PM from someone who was asking about hooking up an LS motor in a 997. For whatever reason his question has gone South and lost in cyber space. If you're out there, please write me again.

Thanks,

I finally have heat! I haven't attached the planned fan on my heater core yet. I only had my footwell blowers to pull the heat in through the stock heater ducts and it worked! I had heat tonight and it was pretty warm. The heater cores attach directly to the heater duct ends right at the flapper with a Spring disappeared for a couple days here in NY so I was able to test the system a little and so far so good.

I also took my car out on the highway for 40 miles to make sure I would break any lines tomorrow morning. I am going to watch the races at Lime Rock and will bring my car in case anyone else is there...

Once again I tested the RPM and temps and could not get above 190 degrees but it is cold outside

3000 rpm in 5th 94mph (assumed and theoretical)
3500 rpm in 5th 111mph (assumed and theoretical)
4000 rpm in 5th 125mph (assumed and theoretical)

Here is a photo of my heater setup. I know that a lot of things in this build are big bucks so this is my two cents on a heater system that is not so "big bucks"... and seems to work so far. Some of the fittings were changed in the final fitting to get the correct fit with the hoses.



And I didn't use the fan setup on the left side yet. I wanted to see if the footwell blowers would be enough. The tip of my heater core setup goes into each of the wheel wells. (I have two of these in total - one on each heater duct) I could add a 90 or a 270 degree silicone hose at the end of the heater core to point the air that is coming into the core towards the front of the car or front of the wheel well...

sweet heater core setup

Hi,

Man that heater setup is way cool. Did you fabricate that yourself? Can you upload more photos of how you mounted it?

Thanks, Mike

Hey Mike,

you need two of these:

2 25" 4"x 6" Turbo Barrel Water Liquid to Air Intercooler Aluminum | eBay

and two of these:

Black 2 25" 2 1 4" to 2 5" 90 Degree Reducer Silicone Hose 57 63mm Pipe Coupler | eBay

along with some hose clamps.






If you have footwell blowers you don't really need a fan at the end of the intercooler. The intercooler is acting just like a heater core. Perhaps someone can fabricate a better one but it really works. It certainly keeps the windows clear from dew and fog. I think it would keep ice off also but I haven't tried it in the dead of the winter. It would be great if there was room to mount it somewhere on the RH engine cradle... Mine has enough room to reach at an angle to the edge of the wheel well right near the rear strut. On the side (driver's side) with the water pump the return of the intercooler shoots back just before the water pump which pulls the coolant back to the motor. On the side where the coolant leaves the motor I tee off and send 3/4 hose to one barrel intercool and the other tee to the other intercooler. Both returns from the intercooler meet at a tee just under the water pump and go back into the return line from the radiator.

Here are some photos of the install...







The wiring took a little bit of work and help to figure things out. Since most of the wires in the engine compartment that dealt with the engine fan had been cut I had to figure out which wire (yellow) triggered the fan previously by pulling up the levers between the seats. That triggered wire then powered a black wire that went back to my manual dial and energized the footwell blowers. I had a thread here:

Footwell blower 89 911 operating question

regarding the wiring.

heater core placement

Thanks for the pictures. Its amazing what you can get on ebay.

For some reason I was picturing the heat exchanger being mounted up front, but I see from the photos you put them in the back.

I ran my cooling lines through the heater duct work (rather than under the car), so that setup won't work for me. Im kinda hoping to use a universal air unit, mounted under the dash.

Somewhere on this forum there is a guy (from TX) that installed one, seemed like he had good success.

Basically just normal with better hoses then original. I have two Spal fans on the rear condenser with room for a third but I don't seem to need it. Everything functions as new. The compressor is just GM.

Hope that helps. I used a local AC company that I knew very well.

Spyker radiator design

I was at a Spyker car cruise yesterday. Thought of taking some photos of the Spyker radiator design and routing for all you front mounted radiator peeps...





Out the hood the hot air goes... I have seen a 911 somewhere on this site with such a hood. Looks fine on a Spyker. Not sure about a 911 but it must do the job.

For everyone looking for radiator options - I still have my 89 911 ls1 with a toy-jet rear radiator. It still works. I have never overheated. I have gone through the thoughts of the front valance radiator setup but when I was done it didn't seem like it was an easy option. I thought that having a simple additional radiator up front would be enough to cool the radiator on long highway rides. The end result was getting a tall 5th gear. I have taken the car to the 1/4 track and never had a problem even on upper 90 degree days. The high rpm on the long road would be the problem and getting the tallest 5th gear dropped the rpm's down to an area that I have never worried about. The LS motors run hot. I do not think there is much of a coolant temp difference between the front radiator options and the rear mounts. At least with the rear mounts you could all test out the theory on your own. Take off the lid and mount a horizontal radiator without much effort like I did and drive it. Mount a good spal fan and you could have your car running in no time. Get your numbers, change a gear or two - you need to do that regardless. Plan on a reallllllly tall first gear and your daily driver/occasional 1/4 car would be perfect. Not sure about a track but 1/4 no problem on hot days. If you drop the rpm you won't overheat. I have the toyjet wing after making my own and trying to retro fit radiators in different wings. The end result was that Clemon (Toyjet) created a decent looking wing after numerous changes. The early wings worked but perhaps didn't look as appealing. Not sure if he is still doing the toyjet wings but his website is still up. My cabin heat setup works perfect too. Its way too simple and cheap for you to try something else. It uses the existing heater ducts with a bullet intercooler on each duct. Simple and works great and works off the existing heating controls. I know renegade stuff works. They are awesome and I used them on everything except the rear radiator. They are a class act and I even visited them in Las Vegas. Class Act period. I just didn't want to cut up the front of my car. Just throwing this out there again.

Not sure what I am thinking knowing that I am done buying toys but I decided to tinker again even after having a perfectly running 89 911 ls1. I jumped into this 80 sc with slant nose conversion Stroker 383 with a purpose built CMS 915 Tranny 460HP/450Torque race car to turn it into a more street comfortable machine. Any thoughts? New thread?

Hi,,
Nice looking car,
Are those steel flares?
What was done to the transmission?
What is the rpm at 60 miles/hr?
Any creature comforts in the car? heat....etc?

Steel flares and fenders. No creature comforts yet. It was a track car. The tranny 915 tranny was purpose built at California motor sports and I am waiting for the paperwork on it.

Hey Yan, I would also like to know what was done to that 915 in order to live behind that small block chevy torque and horsepower.
