The cam is not the issue either, the hat and intake temp is very high. Too high.

I think you are on the right track. Intake heat is a HP killer. Get fresh outside air if you can and cut down any air restriction.


I was able to put 12" x 8" round air filter under the fender, and splash shielded it from the wheel.

Yeah we are working on looking at air to water intercoolers. New hat is being bought next week.

Ok, the car is home for the weekend so I can drive it around. I have a question for the guys here. What is the best air to water intercooler out there? I don't have the real estate for a full air to air. What do you guys think?

I've had Turbonetics make me a couple of them for other cars I've worked on and was very happy with them. They use Spearco cores. Turnaround time was pretty good too, typically less than 3 weeks. CAR could also order up just a core and build their own tanks if you wanted to go that route.

In one of the installs I used a pump and heat exchanger off a Ford Lightning and rigged up my own water tank. The price was right for the pump and heat exchanger and I know they work. The car was making about 700hp and I'm fairly certain under sustained abuse (i.e. 20 minute track session) that the setup would heatsoak and could benefit from a larger heat exchanger, but because the owner typically cruises it and only gives it a quick blast occasionally the stock Lightning heat exchanger was more than adequate.

An air/water setup can and will work well, especially for drag use. Putting icewater in the tank really wakes things up. :thumbsup:

Still, if you can fit a properly sized air/air unit in I prefer that for simplicity's sake, but I understand the packaging difficulties around your RS headlight setup. I also recommending going with water injection even with the intercooler. Depending on how aggressive you want to tune it the water injection will either give you a larger safety margin or it will let you run more timing and make more power... depends on how far you want to push things.

It sounds like you're more in favor of a put together setup instead of a vortech or an aftermarket type of deal? I was thinking of a more aggressive water cooler then what comes with the air to water packages, and then adding watter wetter type of thing.

I've never messed with any of the Vortech air/water aftercoolers so I can't give any recommendation on them.

I'm in favor of buying a Spearco or equivalent core sized for your application and then build the end tanks to best fit your space requirements. Turbonetics has a bunch of off-the-shelf cast end tanks that you can pick and choose from, you might be able to make one work. Make foam-core or similar mockups of the intercooler and fit them in the car before buying to make sure it and the tubing will work.

Turbonetics and other guys do sell air/water kits complete with heat exchanger and pump.

You might get lucky and find an off-the-shelf piece that will work and if you do by all means buy it as it will probably be the cheapest option compared to buying just a core and then having custom end-tanks made.

Water Wetter or any other kind of surfectant isn't a bad idea. You still need an corrosion inhibitor of some sort in the air/water system to prevent corrosion, electrolysis, & sludge buildup just like your radiator and engine cooling system. All OEM air/water setups I have seen use a pressurized reservoir similar to a late model detached coolant reservoir, however they usually use a somewhat low pressure cap on the order of 5-7 psi or so. If you have the space by all means buy an OEM reservoir, all the work is done for you and all you need to do is mount it. Ford Lightnings & Cobras are good sources for reservoirs, pumps, and heat exchangers, as are some of the supercharged C-class Mercedes (but prepare to pay the Benz tax.) There are even some trick aftermarket all-aluminum replacement heat exchangers for the Lightnings and Cobras.

I know the Lightning heat exchangers are about 10" x 26" or so-- they're pretty wide. I don't know if you'd be able to squeeze that around your RS headlamps. It might fit below the headlamp doors though.

have a look here... they're not small by any means.

any update on the situation on the engine yet??? Hope things are going better for you...

Blessings,

Hey thanks. Well we are going to have to have a custom made intercooler made for the setup. It's a water to air cooler, but we are trying to get a lot of size in it. The hat came yesterday and the car went back today so they will put it on next week. Also having a problem with the braking system. The hydroboost works, but when the car is going slow, and to a stop, the car slows down by itself. Kevin pulled the mater off and found that the master's shaft was too long for the unit and cannot be machined down as it's part of the unit, so I have to either ditch the hydroboost or get another master to work with it. I'm thinking about ditching the hydroboost as it's just a problematic POS. Also I may have to order new wheels as the boyds came bent from the factory. The rears are not round and not true. So far, it is still driving me nuts.

dont order boyds there quaity control sucks. I have a nice set of 18 and 20 in DP Engineering wheels I need to sell but thats probably bigger than you want
