I'd like to fit a w2a intercooler to my uzz30 and would like your thoughts. I am about to pick up a new long block ( low comp,cams,rods) to suit a Whipple s/c (taplin kit) and have been searching the net for relevant info.
Currently i'm thinking of getting a piece of ABS plastic machined to hold the heat exchanger similar to the bullet intercooler but having 8 separate water inputs to the heat exchanger to be directly above each inlet instead of a big loop. Obviously a lot more work to do but will it be worth the extra hassle or will the single loop keep the temp even to all cylinders anyway?
I'm out of my comfort zone so any help would be appreciated.
cheers Damo

no looking at a 25-30mm bump. I'll try to keep it subtly but i'm thinking cold air is more important at this stage, this is the second built motor and they're to expensive to keep building.

I don't believe there will be a lot to gain using a 'sandwich plate' type setup. The air charge is just not in the cooling area long enough to be worthwhile.

W2A intercooling is a great idea, but I think you will need to collect the air, pipe it out from the blower and run it through a longer cooler before piping it back into the engine.

what happened to your last motor????

do you have an intake air temp sensor after the blower and water injection?

Absolutely worth it, they have done tests on the Supercharged falcons and the temperatures are close to ambient and as stable as a rock now.

Some of the OEM ones are dual pass as well.

If I had the spare coin I would update my Whipple to one of Kenne Bell water cooled superchargers, similar to this one

Supposed to drop charger temps by up to 70 degrees F

Would be good, no need to modify the bonnet.

no.1 rod on the last motor(bullet built) broke and punched 3 holes in the block 4days after the dyno tune. made 407rwhp @14.1psi with water meth didn't have a temp sensor.
New motor cost me a stupid amount, mainly because i told the engine builder(not bullet) that i'm probably not going to treat it very well and i want it to hold together at 20+psi.just looking at the intercooler as a bit of extra insurance.

major WTF, plenty of guys pushing 300+ on stock early motors!

photos of dead motor and more details PLEASE i'm looking to get the same power from my M112 setup so this is of very much interest to me!

look like std rods with arp bolts. i'm off for a short holiday but i'll take some photos of the old short block complete with special weight reducing holes when i get back.
I'll post the old dyno sheet as well. the old motor had ross 8.5:1 pistons,arp bolts and studs, kelford s1 intake and exhaust cams and springs, wolf v500, 560cc injectors, bullet intake, bosch 040 and snow performance water/meth.
new motor has corillo rods, cp pistons, same cams, port work,custom bolts and studs.
and i'll be changing to 1000cc injectors,a yet to be designed intercooler system and making a new rear plenum cause to be honest the old one was #@^&! new one will take 2 x 90mm throttle body's and be made by modifying the old plenum and cutting up a couple of 4 inch mandrel bends (bit of overkill but better than strangling it i think.)
Oh the old motor had ceramic coated extractors and a mild steel twin 2.5inch press bent exhaust and i'm planning on twin 3inch s/s as the last tuner said it was costing me 50 odd hp. sounds like heaps but it was getting ridiculously hot, the plastic guard for the fuel lines melted off on the dyno as i watched.

How much boost were you running as that sounds rediculously hot.

Was running 13.something can't remember what without water meth and 14.1 with water meth. When it got dynoed it had a single spinner in it and let me tell you that on the late night trip from rocky to mackay I didn't need redbull. Much quicker and much less of a handfull with the torsen thou. The real problem with any engine that sounds so good when your stickin your foot into it, is that eventually you'll loose your licence, go broke from buying tyres or brake it.

I know what you mean about eating tires! even at 7psi with 275's on the back and a torsen the trac light is sooo pretty when it blinks at you :-)

I think the key word there is mandrel. After having a close look at a 2.5" press bend I wouldn't be surprised to find it only flows the same a mandrel bent 2.25".

What was your water temp?

What was the piston to wall clearance?

Are you running a bigger radiator, stock from bar or aftermarket?

No idea what the piston to wall clearance was. Water temp doesn't seam to be a problem. I have a large alloy radiator, and on a cool night if I stay on or over 130 the temp actually drops far enought to be able to see the change on the digital temp gauge. I don't as yet have decent enough gauges to tell the exact temp.
