Procharger intercooler problems.

* The stock air filter fits onto the Mass air while the intercooler doesn't. I bought the kit used off ebay cheap, is the a piece I'm missing going from the intercooler the MAF to the throttle body? Like the one below

The problem is , is that it shows an Lt1 but it says for all years pretty much. My cars a 1988.

 

That intercooler appears to be made for the LT1 cars. I thought the L98 cars were different?

 

Yes they are different. The l98 have different air boxes than lt1 also i think gm changed to mass density and l98 are mass air, so the tube going from the air box to the throttle body are at a different size.

 

If its an LT1 style intercooler you are using, the version that uses the MAF moves the housing down on the inlet side of the supercharger. I'm not sure happens with the L98 cars. Is the intercooler you have made for an LT1 or L98?

 

Oh yeah that would make a lot of sense actually. Thanks for that info, that really made me feel dumb lol. Do you have a setup similar to this intercooler??

 

I sold the procharger intercooler and I'm going to run a water to air setup with the heat exchanger in the same basic location.

Don't feel dumb on the questions, its hard putting together a setup on these things from parts. There's not much info on the web from people making a custom setup on C4 corvettes. Most folks buy a kit and they're done with it. This board has a few guys with good custom C4 setups and several that really know their stuff frequent here.

 

Thanks, Did you have clearance issues with your intercooler?

 

Interesting. I always thought that the LT1/LT4 intercooler had the inlet on the passenger side like the 2nd pic shown.

I wonder if somebody flipped the end tank around to put the inlet on the driver's side to work better for a typical L98 installation.

Out of curiousity, what are the approximate core dimensions?

Also, if you don't have room to package a conventional Bosch MAF between the end tank and the throttle body, I have some ideas for you.

 

To be honest i have no idea , are you wanting its displacement or area?

 

Just rough outside dimensions of the core (length, height, thickness) would be fine. Thanks.

I'd guess its about 18" x 9" x 3" from the pics. Being a vertical flow design, it should still have a fairly large charge flow area. Gussing around 54 square inches.

For the MAF in this application, I'd suggest using a slot-style MAF installed directly into the outlet end tank. Then you could just use a single silicone 4" hose from the IC outlet to the throttle body or combination of 4" couplers and hard pipe if you prefer. This would make for a nice clean installation. A custom tune to accomodate the MAF related changes would also be required.

 

13 1/2 width - 8 tall - 3 1/4 depth

 

Thanks. So roughly a 44 square inch charge flow window. Not too far off of my own 18 x 12 x 4 horizontal flow core which has an approximate 48 square inch charge flow window.

I've measured pressure drops of around 2.5 psi with roughly 11-12 psi upsteam of the IC resulting in about 9 psi in the manifold. I'd guess your pressure drop will be similar, which is within reason.

 

I'm having clearance issues with the hood. Also, does the intercooler just sit up there? Because the stock air box has the to screws that hold it down on the radiator shroud.

 

You have your work cut out for you.

Since that intercooler was meant for later cars with the slanted radiator, the angles are going to be different. You will likely need to do some cutting on the front shroud (baffle) and possibly the upper radiator support.

It needs to be exposed to the airflow in sort of a v-mount arrangement, so you have to at least cut the baffle to open a flow path from underneath. A larger opening will give you some more flexibility on the angles.

I'd be inclined to remove the baffle (and aux fan, if you have one) first, then find a way to fit the IC in a manner that will allow you to close the hood (if even possible). You only have about 2" clearance over the radiator. Cutting the upper radiator support where the end tank runs may give an exta 1/2" or so to work with.

Then work backwards to cut the baffle accordingly around the IC installation. Going to be a pain to get it back in.

FWIW: I run with no front baffle with my FMIC. Just need to be more agressive with the fan control to keep the coolant temps in line. The DeWitt's fan upgrade looks interesting also and should help if more demand is placed on the main cooling fan.

Keep in mind, my FMIC and plumbing is completely different, so this is only offered as general information on what it takes to try and fit an IC that wasn't designed specifially for the car.

Be carefull with the hood, its easy to crack during test fits of this nature.

 

Thanks, it sounds like it is going to be loads of fun . I'll have to wait for my dad's return to mock this up then, I wanted to get a test fit on the motor that is currently in the car to see how it would fit and run but now it seems ill have to wait.

 

Okay lets scratch that whole intercooler. I'm going to do a meth system instead but for now just run the supercharger with an air filter with only like 4lbs of boost for mock up. Would it run to hot or would it be ok?

 

Ok well I'm going to put the supercharger on my car tommorow but I have a few questions. Here is a few pics of the drive side of the motor.

And here's the supercharger and brackets.

Now my questions are. Where do i put the alternator? does it just bolt up??

 

The alternator will mount backwards with respect to the bracket, likely using the top two bolts shown. The top one that bolts into the head, and the other with the idler pulley. Check the spacing between the bolt holes. There should be an obvious combination of holes that is equal the distance between the alternator mounts.

You will may need to some spacers and possibly longer bolts to get it to fit right and be in line with the belt.

I think you're going to have to remove the large pulley and associated bracketry. Perhaps that was used on a car without a power steering pump in the C4's normal location.

p.s. If you do decide to ditch the IC, I might be interested in buying it.

 

I ran a 600B with dual intercoolers for many years and just converted to Methanol Injection. I never could get any decent boost out of the Procharger system between all the plumbing for the intercoolers and the belt slip. I removed both intercoolers and all the associated plumbing and got an extra 3 lbs of boost.

 

so here's the deal with the procharger setup. It's setup for a ltx based motor with a slanted doghouse like previously mentioned. Many guys run the blower discharge tube to the intercooler in this order; blower, blowoff, mass air meter, intercooler.

the procharger setup is too small for anything serious and anything lesser will benefit more from alky injection due to the combo of cooling and octane. I'd sell it and buy a alky kit. It's easy, light and you'll need it if you ever turn up the wick later on.
