I will be able to post something about efficiency of intercooling a 2300ax Lysholm in about a week. "MetalMan" (Brett) and I are finishing the project on my truck tonight. It uses a Spearco 2-230 air/water intercooler and 3" aluminum mandrel bends. I know some of you have known about this project, and I apologize for it being a month overdue -school strated and this kind of took a back seat for a while.
I would be able to test boosted air and after the intercooler air temps. for efficiency. I would like to compare these temperature numbers to the Radix. I think mine will kill it as it is not getting heat soaked by the heads. I never got it on a dyno for bef/aft numbers, but temp readings should give good data to look over.

PS. If anyone ever wanted to do a 3.3L Lysholm on top of an aftercooler like the Radix setup, it could be done. I think there are better ways of doing it, but that would be very clean. I think it would cost alot like sleek silverado mentioned though. I too would go with a turbo over that setup for the cost being about the same.

Dont the 8.1L kits use a 3300 blower? I can get hp before and after numbers on those setups for you guys.

Here is the 2300 setup. From the Truck Builder magazine testing, they made 512hp 740lbs on the stock pulley. **look at that pulley though. i don't know how you would get much smaller. I guess I can't find stock 8.1L dynos

can't wait to see some pic's!!

the 8.1 whipple kit uses the same 2.3 blower.

Ryan get some pics of your setup. i am going to run a pro charger and fab up a air to water intercooler. not 100% sure of how to do it yet want to see some ideas.

Edit: damn it you beat me by 3 min. any ways i did do some research about using a KB blozilla compresser for the cobra in place of the eaton on the radix system. It could be done with some custom machined parts. But i dont think you can just buy bits and pieces of the radix system. and the KB head unit alone was lite 3-4000 $ on there web site. i was close to having it all figured out but then realized how much it would cost and decided if i was going to spend that much it would be on custom twin turbos.i will eventualy custom fab an ati settup i feel it will work better for my application.

If it is a 2300ax blower, I guess that would explain the pulley size and the need for an intercooler

I will make a post soon. It is insane!!!

Here you go sleepersilverado:


This is TIRBRNR's setup and what they made after intercooling. The setup is very similar to an ATI kit, so I guess it could look something like this. btw I like this setup
HERE is the post I got pictures from.

sweet thanks i could not remember who did that.

Hey Parish, I think in order to do this you would have to have the exact same inlet temps. going into each blower. It is a linear thing, and I am not sure if the 20* can just be subtracted from the Whipple output. I know this will sound a little bit engineering-ish, but that was an Input variable for their calculated output temp.

To explain: you cannot have f(x)=2x+4 an equation of output temp. and then plug in x=20*. This would yield f(x)=2(20*)+4 => 44*and then subtract the 20* to get an output temp of 24*. In the end, I think at that 14000rpm and 20* inlet temp, the 2300ax should be around 170*-180* output temperature.

The Magnuson chart is pretty non-scientific compared to the Whipple chart. They are missing an input for their Delta Temp Chart on the Radix. You cannot find temperature output of a blower without knowing the temperature input I think customer service made that chart

mubo jumbo to me! seems to me there is a spacific temp rise based on compresion of the air and then factor in the efficency to add even more heat, i dont think the intake temp is going to make that much diference in the delta.

i think the bigger diference you are not seeing here is that at the stated psi and rpm's the whipple is pumping alot more air, over 200cfm more, i gues it would be better to compare the delta temps at the same flow, not the same psi and rpm.

if you look for 820cfm at 10psi then you only have to spin the whipple to ~11000rpm with a temp delta of about 180deg f

i am kind of talking out my *** here so make your own conclusions and tell me what you think.

that's cool, I know the Whipple graph is confusing, but I think I am reading it correctly.
I think you are correct in that the readings would be a better comparison if looked at by cfm rather than psi and rpm.

Are you doing turbo(s) still? Now that is something I have not looked into before -those turbo maps confuse me
