nevermind... a custom adaptor plate w/ 3 holes on one side n six on the other..duh
but what about the less power scenario??

moparzrule · 05-05-2005, 04:52 PM

You won't really make much less power being non-intercooled at 10 PSI, maybe like 10 HP tops. The fact thats it's a suck-through style with the gas being atomized by the turbo gives an intercooling effect, almost like alcohol injection does.

The second to last picture in the link you gave in your first post shows the grand national suck-through style being used!

That's exactly what I'm referencing.

yeah, but my question is... intercooled or not, does this kind of set up make less power than my other route w/ the 4bbl intake and 390 carb? I didnt know if any HP was lost in the turbine??? or any wierd $hit like that. I've "heard" that some power is lost setting it up this way.. also, what would you guys pay for something like this?

and where is my grainger to be installed.. what line?

mwinkle353 · 05-06-2005, 07:40 PM

I figure that you'll make similar power to an non-intercooled blow through setup. Maybe just a tad more due to the fuels ability to soak up a little heat from the compression. Plus, you will be able to use just about any standard carb that doesn't have to be setup for boost, since the car won't actually see that boost.

The grainger can be installed to just about any boost/vacuum source. But I like having the turbo's outlet tapped to accept a NPT to 1/8" hose barb. That way I get the most direct boost source. Plus, the shorter you make the wastegate control boost/vacuum system, the faster it reacts and reduces the possibility of boost spiking.

awesome... i just won that gran nat. blow through setup. i over paid but i got a fat tax refund in the mail and i got a buddy that works for a diesel shop who will rebuild it for free (so long as i paint a fender and gas tank for him)

I understand the basics of turbocharged cars but when it comes to vacuum lines, i feel like a black kkk member not knowing what the heck to do. I guess im really clueless when it comes to what vacuum lines i need hook up/use to make this work. ive basically gone off that website i mentioned, but he doesnt mention anything about vacuum lines. (also, countless hours of searching other sites..turbomustangs.com...)

I understand that i'll need to tap into the boost source to install a boost gauge, but what all do i need to run other lines to? (obviously the line for the grainger valve has to end up somewhere) where should the other end of this line hook up into?

thanks for being patient

wastegate?

moparzrule · 05-09-2005, 06:39 AM

^yes.

Alright, now that you have it coming, this is what I would do. Your stock 1bbl manifold will actually work just fine, turn the turbo so that the compressor inlet is to the front. Make a simple plate adapter to connect the outlet to your intake. The turbine housing can be "clocked" so the inlet points toward the driver's side fender. Once you get the location setup, make any additional braces needed to insure the assembly stays where you want it. Select your carburetor, then you may have to make an adapter to orient the carb so you can easily connect your throttle linkage. Is your car an automatic? If so the kickdown must be correct, it is actually a throttle pressure control and is critical to proper shifting. After all this is done and the turbo rebuilt, get your exhaust plumbed up to and out of the turbo. Last, have fun! Eat lots od ricers!

finnman1 · 05-09-2005, 12:45 PM

Ha ha, eating ricers is why i started this project! What do you mean by "clocked"? what all does that involve? Also, i've got easy access to a holley 390 if i want it.
Also, what do you mean by making an adapter to orient the carb to connect the throttle linkage easily? What's the best way to do this? Also, will stock linkage work?

Step by step how to setup a carb for blow-through.

**85lebaront2** · 05-11-2005, 06:14 AM

I didn't think you were going for a blow through carb. As for the carb orientation, on the early GN, the turbo shaft went across the engine and the carb sat on the driver's side with the linkage on the outside. Since you have a long engine with a pretty good bit of clearance on top of the intake, your turbo's shaft needs to probably run parallel to the crank. Your carb should be oriented so it has the throttle shafts across the engine as it would sit on a V8, with the primary throttle lever on the driver's side. Go to http://www.lokar.com for linkage they make some really nice setups for just about anything. Hope this clears things up.
