Another question about V8 conversions

[GLASFIBRE]

Here's a sample of the exhaust on the 911 V8. It's 2 1/2 Stainless and when installed on the car it all appears STOCK

[BoxsterGT]

Any photos available showing details of the cooling system? I would like to see how the RSH system exits the air from the radiator, as well as the RSH radiator itself.
I wonder if the $1100 cost for their custom radiator w fans is justified.
Also, are they now using larger 1" and 1 1/4" hoses instead of the smaller (18' of 7/8" & 26' of 3/4") ones described in the porchev web site?
Any photos of how these hoses are routed thru the rockers? How about going down the original heater tubes inside the car? These are not needed for heat any more.
Which brings up the question of heat. RSH says they have a heater core & shroud to fit the front blower assy.
Anyone have photos of this?

I'd like to see the details of that cooling system too. I don't want to change my fuel tank like some have done. I have seen some pictures of holes put in the wheel wells so air vents out there.

No matter what it seems something like this will have do be done to the front:




Unless you go this route (he wants $1795. for this rear mounted radiator system):

[BoxsterGT]

For a SC, I would rather use something like this....



but don't know if enough air can come in.

I don't want to change the fuel tank either.

My question is where does the air exit from the radiator?

I have found pics of where the air is vented out into the wheel wells, and the spare tire is taken out and battery moved to make room for a radiator, and I have seen some ugly jobs posted on Renegade Hybrids' "Wall of Shame" that I would like to avoid. My fuel tank is virtually brand new, so I don't like the idea of changing that out.

As far as some people not liking the idea of modifying a 911 like this to begin with---I bought this 1972 911 already with a lot of modifications. For example, it was not originally a convertible, and it also has electronic windows, so this is not an original 911 to begin with. However, when I look at places on the car that I would have to cut to make room for a radiator system, I am hesitant about the idea and I am seeking more information about this whole deal.

I have built 3 V8s. Weight pretty much equals out. Use Meziere in-line remote water pump - trouble free cooling. Be sure to take the time to properly shroud the radiator. Build vaccum lip underside of tub just before radiator hole - it is worth 15 to 20 degrees in cooling. 993 mufflers work swell.

I miss my last one (sold it for very good $ to some cat in Kuala Lampur - Malasia) but sure like my old 79 930 that I have now even though I have a hard time contorting to get into and out of it. How fast you want to go depends on how much money you have to spend. Pelicanneer Schnell knows a hell of a good welder if you need his expertise!

Is this what is needed on both sides of the front trunk.........



to exit the air from the center radiator? It looks like a lot of the structural integrity is lost.

Instead, I think I would like to try a small radiator on either side, as with the 996 & Boxster.

How does one calculate cooling capacity? Is it the Sq Inches or mm surface area of the radiator?

There are 2 radiators, porchev that vents out to the wheel wells, I dont like that because it seems to weaken the structure of the car, and renegade hybrids which your supposed to shorten the gas tank and vent down. Im thinking of adding a hood vent to mine and venting up as I dont want extra air going under the car. I have the renegade radiator.

[BoxsterGT]

I just realized that RSH and Renegade are two different companies. Got to take a closer look at both.

I would rather exit the air into the fenderwells than under the car, but don't want to weaken the fender structure.

Perhaps a vent up thru the hood would be best. There is an excellent posting I just read on doing this.

Still want to know about the size & routing of the coolant hoses, w photos if possible.

Len

[aftermath]

look at
http://www.renegadehybrids.com/

and go to conversion kits\911\customer cars

if you want some pics, they dont show a lot for radiator installs though

[GLASFIBRE]

Here's several pictuers of the heater assembly for my 911....

[vanwyk4257]

I would think the best way to go would be to go with a short/wide aftermarket radiator if possible, lean it forward into the front of the tub with the bottom near the gas tank, then vent it out through the hood ala' GT40. The question is whether or not anyone makes a radiator in the dimensions that would work, and whether or not it would provide sufficient cooling?

Got a link to that posting Len?

I think thru' the hood is best, like this 525 HP 914-V8 uses;

I am planning to go a step farther than the 914 shown in the above video, at speed you have all the energy of the air pressure going to waste usually, my thinking was to put an angled plate and side panels behind the radiator, so the area behind the radiator is sealed to the side, bottom, and back when the hood is locked down, to give a downforce effect.

And there is a theory that the outlet should be about twice the size of the radiator for better cooling, the logic I believe is that it will create a partial vacuum at the hood escape portal, thus helping to suck the air thru' the radiator better...

I got flamed hard for even asking about any conversion on rennlist. No matter what you gotta love some of the craftsmanship on these cars

Thanks for that link, here is another basic version of that I found somewhere:

Thanks!

I was originally planning on using a 914, but the 911 conversions seem substancially lighter

Another decision to make

[BoxsterGT]

Thinking more about how to keep the chassis intact & maintain structral integrity up front.

Shortening the gas tank and dumping the exit air out the new opening in front of the tank seems to be the best way.

I am not going out on the track, I just want a great cruiser that goes when I hit the loud pedal.

This allows for a heater core up on the luggage tray and the battery in the smugglers box.

Still need photos of how the coolant hoses are routed along or thru the rockers or under the floor w rectangular steel tube.
