Gentlemen,

Has anyone figured out how to lay the radiator in a C5 or C6 forward the same way Corvette has done with the new C7?

With an air extractor hood, this change would certainly improve cooling and reduce front end lift.

The pictures aren't showing up. Many have laid the C5 radiator forward.

I certainly would like to see some pictures of how it can be done for a street - track car. That would be more difficult than a track-only car.

The intake always becomes untidy with this setup. Many race cars remove one of the headlights and tuck the intake filter in there (replacing the wide filter with a simple cone). The pipe is always custom. The radiator hoses are custom too. It also allows one to remove the radiator support in the C5 which allows a better undertray to be fitted.

Not sure why you would want to do this on a street car, other than to have a trick setup.

I am about 30 days away from finishing an engine upgrade. My 11 year old 450 HP LS6 is being replaced with a 700+ HP naturally aspirated LS engine. I am looking for all the cooling improvement I can achieve as part of the package.

Nice!!!

I would want to lean my radiator forward too...

Vented hood?

SouthernSon

Do you plan on trying to retain the A/C?

I've seen a few of these, and in every instance the hinges were eliminated and hood pins were used. I'm not sure if it's necessary or if it's just because they were all lightweight c/f hoods. Just something else to consider. I plan on doing this over the winter to my track car.

Here's a picture of how Beretta did his, which is how most C5's are done:

Any c6 setups?

Here is one I did on a C6

Race cars are easy, and as Jim has seen on all of our race cars...they have been done that way for years and years now.

The hard part for Jim is going to be doing this, while keeping the A/C working on the car.

I think you are going to have to get creative with the radiator and A/C as a unit, and either modify the frame of the car or use a different size combo to go into it. The intake and hoses will be the easy part.

Pumba

Absolutely ! !

Yes, I would want to do a hood vent that was exactly like the Pratt and Miller C6R Corvettes.

Thanks Anthony.

You understand exactly what I am thinking.

I have just finished development work with C&R Racing on a radiator module for the C5 Corvette. The module uses a Denzo double-pass radiator that fits in the standard C5 package, and includes both an engine oil cooler (80k BTUs) and a power steering cooler in the driver's side tank. It has a pair of SPAL cooling fans as part of the module. It is slightly shorter in the Z direction than the C5 radiator.

C&R rates the module as being capable of cooling 1,000 hp engines. So, I should be fine with my 700 to 800 hp LS engine.

0Anthony @ LGMotorsports

You know that is going to require something like this right.......

rmackintosh

....yeah....I think trying to fit in a C5R/C6R hood in the mix and you might as well forget the "street" portion of street/track and just tear the car apart and fab that sucker in!

The race car?

You will need a set of Kinsler ITBs and accompanying airboxes and a standalone ECU. You will lose the OBD-II port, which may hurt when trying to get an inspection. You will likely need a standalone ABS if you want ABS. You may need to figure out a way to retain your OEM PCM if you want the rest of the car to behave.
The fab is a totally different matter, which will include chopping the front frame rail connector and welding alternate supports if you want to truly mimic the setup. I think it also has the engine moved back as well. The setup will not function anywhere near its potential (to the point where its purpose will be defeated) with a fan/shroud/AC setup, which is why the race car had/has the AC in back.

ALMS rules state the engine has to use stock engine mounting locations. Note that doesn't state stock height or exact position.

Knowing our own car...the A/C was in the back of it for a few reasons.....
-No drive location for the A/C compressor up front
-No room for the A/C lines under the hood
-Didn't want the added weight on the nose or in front of the axle center line.



I'm thinking Jim isn't going to do quite as large of a vent as the ALMS cars so it can be done....look at the C7, but notice the opening is much much smaller.
