I have a 2007 c6 with an Lq9 408 stroker with an 88 mm front mount turbo. 700hp on gate at 14 psi. Just got the car back so I haven't had alot of time driving it. Haven't had it to the track yet or anything just in town and highway pulls. I understand I'm going to have some heat issues no matter what but I'd really like to be able to drive it around town without having to worry about heat issues. Right now it's getting over 245 when heat soaked and in town driving. I know the intercooler is blocking airflow I have a large radiator with 2 large spal fans. Water and water wetter only. I'm down to 2 options either an electric water pump / electric booster pump or moving the radiator to the rear of the car. Does anyone have any ideas or suggestions? Thank you.

post pictures of it n i would suggest making a tubed front and spacing the Intercooler n radiator a bit

What radiator? What fan setup?

Robbs03

Sorry it's dirty had some coolant swap out issues

Robbs03

Not sure what radiator the builder got it. I changed the fans out to 2 really large spal fans.

Robbs03

I don't know where there is room for that it is really tight in there. Which I understand that space would help but I dont think it would help much sitting at a stop light I could be wrong though.

this setup looks pretty similar to shlbykller's does he run into cooling issues too?

Robbs03

Very very similar. Same builder Shelby killer is a good friend. He also has coming issues we've been trying to figure out the best solution together. My idea was the electric water pump. His idea was relocating the radiator.

nenji01

I would cut holes in the front of the support beam in between the Intercooler n radiator and maybe in the bumper if That doesn't help or eliminate the front beam all together for a tube or smsller beam n then for stop n go traffic you could add external coolers maybe one for oil n run one together with the radiator and place them both on the fog light bents

I have changed my turbo setup about 4 times now so I have a fair amount of knowledge about what is happening..

Basically right now you just have 0 flow to the radiator. With everything stacked like that the fans cannot pull through it. With the oem layout the radiator is tilted and is relying on high/low pressure zones to draw air through the radiator. When you stand them up like that you are relying on the air to go through the little 22x4" hole in grill, then through a 3" core(at the least) and then an ac condensor, then a radiator. With my latest setup(http://derale.com/products/electric-...-gasket-detail), which is standing up like yours, I was able to get a big enough fan setup on the car to bring the temps down at idle but at speed it just isnt enough.

Robbs03

What's crazy is that at speed or while driving the car will cool down. Which I know shows that air flow is an issue. But sitting still running if it gets to 230 I can put it in neutral run it at 2500 rpms for 10 seconds and it'll start dropping temps not alot but a little. I don't think a fan set up is going to help those spal fans I have move a ton of air and we have a good shroud.

what fans are on there? There is a big difference between a fan that "flow" 3000cfm at 5amp and a 1500cfm at 25amps. Amps are what will cool, not the cfm.

They an "ok" fan. 10amps at 0 static pressure(which basically means 0 restriction) with 1100cfm. Put any restriction in front of them and they die... hard.

I would suggest looking for a better fan setup. I know you are lacking space but I would see if you can find something better.

maybe could squeeze these -

Ya the problem is there is absolutely no way I could get 2 of those on my radiator. Surely 2 of the one I have would be better than one of those right?

schpenxel

Some have had good luck with brushless fans like D3PE uses.

Robbs03

The d3 kit looks like it uses the exact fans I'm using already?

schpenxel

It does, doesn't it. I thought they were using different fans but maybe I've got it mixed up

Ls240sx

I think in that size that is about the best you are going to do unfortunately. Maybe some thin pushers on the front? At one point I had these in between my ac condenser and intercooler -

Robbs03

Ya that's not a bad Idea I have some extra small puller fans I could put on the back of the intercooler. How did you mount them between the intercooler and the condenser? Just a customer bracket?
