4.5 liter Whipple build
It looks like it's all about the pump you use. I asked Whipple how much pressure I could run through the I/C core safely and I looked for the best pump I could find for that max pressure and it works great, so far. I also installed -12 hose and fittings <(I had to drill out the fittings) throughout the system and used a 5 gallon water tank as my supply. IAT temps stayed low even as I drove it around the block a few time. No, I don't have any hammer time passes on it yet I think it's gonna work fine... I'll update this after more high boost testing.

Nice, does the throttle body just point to the firewall and stay open, or are you able to run a charge pipe somewhere with a filter?
Always had a soft spot for these Whipple LS's.
Sent you and inquiry a while back about one, this makes my wheels start to turn again, have the same tight quarters as this fox body does in my project.
Curious to see results, of both of these projects.... I figure since the COPO does so well, that these kits must be ironed out by now.
They are still around 7000.00 for the set up aren't they?

I found a much better pump. It's pricy @ 300.00 but it's bad *** and pushes water very well. I'll take a pic tomorrow when I get back to the shop.
The engine that I'm using now is just for testing until ERL finishes the bullet for this project. The engine in it now is good but not near as nasty as what's coming... I wont be able to see what this blower can do until I get the new motor... and I can't wait to get my hands on it!!!!

That core you showed looks like they stacked two, that will add core restriction X2 as well as doubling cooling capacity as long as you have enough water. General rule is 20GPM will cover 1,000hp if the core is capable. Most cores are compromised based on mechanical needs of available space. When you use them in drag racing you typically see the cores used as heat sinks, in those applications the IAT will climb until you lift, starting at low temp supplemented by ice (high delta helps smaller coolers do big work). In steady state with proper water flow the IAT will stabilize, not climbing at all. In realistic racecar stuff the IAT will stay below some specified limit while operating at a realistic duty cycle. More than likely that double core was used on a boat where the engine is operating steady state for extended periods. Testing will show the weak point in any system if you record/watch inlet/outlet of water/air you can figure out if you need water flow or bigger core. Your 2.9 Chinese core was following near 1-1 IAT and water exit temp, both climbing rapidly. This says water flow is required, in that case the core could not do it.

old post but I didn't see it listed anywhere. Is there a dimensional chart anywhere for the front feed 4.0 or even 4.5 setups? Just wanting to see those values to determine fitment
