Hey guys, I'm about to order a core from BellIntercoolers and I know what height and thickness I want to run but I'm wondering what width most people run on C5s.

You guys running 25", 27"?

ECS, A&A what width do those run?

Anyone have any fitment issues with a 4.5" core?

0Arun@CCP

A&A has some that are 27" and some that are 25", ECS is around 28".

wilson34

Yea, I guess I'll be ordering up a 27.10" core.

Thanks Arun, oh and also, I'll be needing a modified 10 rib A&A bracket in the near future

0Arun@CCP

No problem bro-if your going to run a F1R, get the biggest core as possible-the blower makes alot of heat. I was actually thinking of getting one of there 4.5" thick cores. A 27" x 6" x 4.5" core flows over 2300 cfm!

With the standing rad setup it should fit in there nicely.

wilson34

Exactly the core I'm going with. Only running an f1c but I figure if I'm going to doit be prepared for the future upgrades.

The setup will be that intercooler core, your modified bracket, f1c, flip drive, 10 rib, elec waterpump and a restrictor plate system for boost control on the fly.

Can u get the intercooler with the ram air vent?

What does the intercooler cost?

wilson34

You can buy that directly from a&a and I think it is $1000.

Bumping this back up to see if anyone has had any success fitting a 4.5" thick core on their C5.

I saw TTIX made a 4.5" core but I don't know of any cars running one yet.

0Arun@CCP

I'm going to start mocking mine up in a few weeks. I'll be getting a 28" wide core for maximum cooling potential. I will also be going from 3" to 3.5" tubing to the inlet of the cooler to help keep heat down and ready to adapt to a F2 at any time. Although I'm very confident the F1R will make 1050 rwhp with relative ease.



It will look very close to the my current cooler:



My current cooler never saw IAT temps rise past 90 degrees in the hottest of temps-and I was only running a #10 and #15 nozzle.

Is the one pictured a 3.5"? I'm half tempted to buy a 25x9x3.5 core from Treadstone then weld up cast endtanks to it from Treadstone aswell because that would be about $150 cheaper than just the core from Bell.

Then part of me says doit once and doit right. I'm just wondering how much of a benefit and or headaches I would get from the 4.5" core. Going to be using an F1C but no idea if future blower upgrades are in the mix.

0Arun@CCP

The Treadstone cores are real nice IMHO, but the 25" core just won't cut it with the heat the F-series blowers put out unless you spray alot of meth.

You can take 2 cores and weld them together-I would use the cast endtanks-nothing better than a sheetmetal endtank-makes a huge flow difference.

The cooler shown above flows an easy 1900 cfm plus-I'll probably be selling it in a few weeks and if there's a demand I'll make some more.

Cost should be around the $750 mark for a 28"x6"x3.5", when I get a 4.5" done i'll let you know.

I'm running a 4.5" core, also look at the hight of the cooler besides just the width. I believe the A&A is about 6" tall, our standard core is 8" tall, although we have made some custom set ups that were taller. Also look into pipe sizing, we have a standard outlet size of 4".

Arun, let me know as well, when you finish up the 4.5" core. I'm still running the original A&A IC with the F1C @19psi....Since I'm dropping a pulley size this season, I think I might need to go with the largest one that'll fit.

0Arun@CCP

The taller cores actually flow less-plus they need to be layed down which affects the airflow across the core. While they will cool better, but there is going to be more boost lost.

With the core as shown-my IAT temps never went above ambient while cruising.

With the layed down version, your very limited to a small air filter-those small airfilter's will rob an F1R of over 50 rwhp. I like the inverted cone conical filters-they work great!

DOUG @ ECS

I keep my core vertical Arun, with the thicker core, being taller does not effect flow, yet helped IAT's slightly. Our air filter on a Novi 2500 dropped ET .04 on average, I dont think thats 50 rwhp, but we do not dyno those cars. Track tuned..

wilson34

From my understanding of intercoolers, tube length is not as important as tube quantity when it comes to cooling. But I could easily step up to a 27x8x4.5 core from bell. I think with a core that tall I will run in to air filter and radiator angle/position issues.

You guys make this decision hard on me but I'm leaning toward a 27x6x4.5.

0Arun@CCP

That's exactly what happened-I had to lay the rad down like the ECS setup and it forced us to run the filter supplied with the ECS kit.

The F1R did not like that small filter infront of it, there was a 50 rwhp difference. Now with the inverted cone filter I'm not sure how much of a difference it would make-on the D1SC setup we pulled the filter and it made no difference at all.

DOUG @ ECS

Was the filter dirty Arun? I pulled the filter on the last C6Z YSI build we did that put down over 1000rw, and saw a 16rwhp differnce. I have two more builds like that in the shop now, I'll try the comparison again to double check, but we didnt see anywhere near 50rwhp.

0Arun@CCP

YSi is different dude-it's the F1R and C that don't like the filters, YSi don't like intercoolers either-try it without one and just turn up the meth.

0Arun@CCP

Well, I did some measuring and I'll be sticking with the 3.5" core. The 4.5" will end up too close to the condencer and will hurt airflow to the rad.

I have a Bell 29"x6"x3.5" core that I'm going use and test with the new F1R combo.

Just by looking at it the Bell versus Treadstone-it looks like the passages in the Bell core are larger and have less cooling fins-this would mean it will flow more but cool less. With a dual nozzle meth setup this may not be an issue.
