Road Test.......Whipple-charged........
 

Test drove a whipple yesterday for a friend. The owner of the vehicle offered him the complete setup for the cost of removing it and going back to stock. His intent is to hopefully adapt it to his 1984 EFI 5.0 Mustang.......with a little help from me. We're in the research phase right now for adapters/manifolds, etc:

Impressions? This thing is a complete DOG. There's considerable lag, in a turbo-like manner. There's no power off the line, and only 'noticable' power when you get into boost. 6psi was the highest I could achieve after several attempts yesterday. Not a prayer of scratching the tires off the line, which is interesting, as this thing should be able to in stock form.

Upon further inspection and review, I believe this charger is horribly undersized for the application. It's quite small compared to the kit Whipple currently sells, and the mounting is totally different.

I'm not sure where this kit came from or what it was intended for.

That looks awfully like the Mercedes setup, like the SLK230, but without the EM clutch. Looks like the controller is piggybacked to the factory ECM. Possibly something is getting lost in translation?

The fuel/spark controller is indeed piggybacked. I didn't have time to inspect plugs to tell the story.

That doesn't look at all like the kits I've seen for any of V8 or V6 versions of the C/K trucks and SUVs. Maybe it wasn't a kit from Whipple, but merely used some of their components?

What kind of ignition system is it running? I'm not familiar with those engines, but weren't they running the distributor-type HEI system, or is it coilpacks? And has any DTCs been pulled? (I know if you had the time or the scanner handy it would have been done already).

My goal isn't to fix this one. It's to gut the kit off it and install it on a 5.0 Mustang if possible.

And return the Tahoe to OEM components.

Could be a fun project. Hope you can explore the inner workings of the Whipple and take some pics along the way.

There is no major difference in a Whipple as opposed to an Eaton other than the rate of twist and internal mechanical tolerances.

They are both twin-screw roots-type superchargers.

How are they coated?

Take some shots of it after removal. I'd still like to see. 8)

I'm staying right out of this.... But I will Add that the blower on that truck is not the right set up

I have used them before and know of several chevs around blown by whipple and have never seen that type of set up... None of them are dogs either I suspect that for the cost of adding a New blower to that 5.0 VS using this blower would be about the same. Noting you mentioned not being able to pull 6psi out of it... IMHO new would be better. Although I DO NOT underestimate your ability to rebuild that blower Will just think the cost of parts vs new would be close to what a kit designed for the car would carry.

I don't have any direct experience myself, but I have seen many of the aftermarket blower kits for trucks not working much better than stock when just slapped on out of the box. I know one kit that people use on the Denali's (not sure ofthe kit brand) really needs better injecots and a custom tune, since the piggyback piece they send with is almost worthless and difficultto install at times.

Piggy backing is the lazy mans Mod.. the only time I trust something like that is if it came from someone who like Banks who tests tests and tests some more. Even then you run into problems.. If you are going to do something do it right Get a tune.

If anyone can swap out that blower and make it work on another engine, the Wren can do it. ;)
If it can't, they he will sort it out and not simply piggyback it in hopes that it'll work.

Tuning is key and that unit may be undersized or incorrectly installed for the truck application.

That SC looks like it belongs under the hood of a Mini Cooper S. :?

Wow, did Paul just say that? :D

Yeah, that 'charger is kinda in a funny spot. All the one's I've seen are on top.

The other thing there is no nose drive... Im having a herd time believing thats a Whipple.. I have looked over my old books and havent found it yet. Looks more like a procharger... :?

I have Whipple books going back 5 years got a model number.?

It's a whipple. There is no question in my mind about that. It's a much older kit though. And it is a kit that bolts up fairly well.

I'm surprised nobody has commented on the black coating. ;)


(BTW, I already suspect a Gen3 M62 will outflow this short-rotor POS, which would pretty much rule it out for a 5.0).

Whipple has been coating there blowers for a while. They even have colors now

Hey Shadd, I never said it wasn't. My terrible times and 1/4 mile speeds with a Gen V are testiment to that. :roll:
I'm the first to admit, my set up needs to be tuned.
I'm just not the one to do it. I don't have the equipment, patience or know how.
Got some learning to do or maybe a long drive to visit Intense.

All cost more than I'm able to spend right now. :(


I'm pulling so much KR right now, might as well pop on the 2.9" pulley.....can't be much worse....

.....oh wait, I just saw the pic of that holed piston at Hoser Boosty's. :shock: :lol:

You don't get it. ;)

If you spent more time in Forced Induction, or took a good look at my supercharger, you'd understand my point.

Is it really the black colour Bill or the type of coating that transfers the heat.

The Whipple doesn't appear to have that wrinkle black finish you have. It looks smooth.

So is that where you got the idea from?

That thing is TINY... Is the rotor casing even as large as an M62?

Whipples are twin screws, which are the most efficient of the main three SC designs. A few W body guys had gotten into them over the last few years.

But i still can't get over the size of that thing, for a 5.7L V8.. :shock:

No, it's not wrinkle-finished, but it is rough. And no, that's not where I got the idea from.

Jason, the size of that dinky POS is the first thing that hit me between the eyes when I popped the hood.

will whats the model number on the ? I have a couple books at the shop to find the application.

Everything I know is posted.

My Roush unit as well as current whipple units are so much larger. I guess that is a pretty early model on that truck?

Based on the information I've found so far:

1. It is a Whipple. EARLY whipple. More than 4 or 5 years old.

2. It is a kit.




What I assume:

1. It isn't a kit for this large of a displacement.

2. It's too damn small for this displacement.

3. It runs like shit.

Just givin' ya a hard time Paul. ;)

Hey Boosty, I'll bet that'd work pretty good on your Grizzly.

That'd probably work nicely on a 1.3L suzuki sidekick.... Wonder if he'd sell the whipple... I'd like to add a little oomph to my push mower.

We're finding similar-sized whipple kits for the 1.8-2.0 liter VW community. This whipple is roughly in the same class as an Eaton M45.

So just going by displacement... if you could find another identical unit, you could use two of them on the 5.0 project, and still not be pushing too much air. :lol:

I dunno if i'd have that on a 2.0 myself, it's barely bigger than the brake res and tree it's near :lol: :shock:

I stumbled on this on Ebay....almost a carbon copy of what you drove, aside from the mounting locations....

Link is fixed.

Hey sandrock, are you sure that is the right link? :lol:

Damnit.

Link fixed. Or in process of.
