Hey all,

I didn't see if this had been asked before, so I'll ask anyway.

I have a blow thru carb setup on the camaro, with about 8 psi or so from a vortech S-trim. I have no intercooler, and 9.9:1 SCR, so I am going to use WI for obvious reasons. I have a recirculating valve installed just before the carb hat that stays in the open state while the motor is delivering a vac. signal.

Where would be the best place to put the nozzle? I have heard some say that you can go into the inlet of the blower (like they did on WWII fighter planes), and that it helps keep the blower cool, plus it "mixes" everything up very well.

I have heard that you can put the nozzle right after the charger, so that as the air flows through the intake piping the alcohol/H20 mix has more time to cool the charge air before going into the chambers. But there was a concern over blowing the alcohol mix out the recirc valve in some cases. Would that be a real issue or not?

Then, lastly, some put the nozzle in a plate under the carb, or in the intake just under the carb. This allows the alcohol mix the least amount of mixing, least amount of elapsed time for cooling the charge, yes? I may be concerned about mixture distribution this way.

Which way works the best? Any recommendations?

Thanks for any help!

most people running carbs use a spacer under the carb and mount the there jets in there..

please post more engine pics of your setup.. im getting rdy to install a procharger F1 on my brothers 71 Elky SS that has a BBC

okay, I'll see what I can dig up tonight. If you were doing a vortech I could send the AutoCAD file with the bracketry for a small block - that could get you started if you were making your own. That goes for anyone else as well. If you want the drawing, I could even send it in PDF.

are the brackets the same for a BBC ?

I don't know. I don't think so. The bolts I used are for the accesories on a small block - there on the front of the head. Surely they would be different on BBC.

And I forgot about those pics last night. Sorry. Will try to remember.

please do post some detailed pics of the blower and carb setup

[hotrodf1]

Here's a few. I guess I don't have a lot more detail right now, but if you are wanting more pics of a specific area, let me know and I can go shoot it for you.

Right now the air filter is attached directly to the blower inlet. I am probably going to be adding an elbow there and putting the filter up in the corner just behind the radiator support, then boxing the area in so that the air coming in the front of the car is what it breathes in. I could add a injection nozzle in that intake pipe for the alcohol if that makes sense. To go along with that, I may reroute the discharge piping as well, and then I'll powder coat everything in the ol garage oven.

I don't know how else to post the pics other than attaching them, hope that works okay. Makes it hard to comment about them though.

you should have seen it before I cut the old out and put the new in. I think the car had a rough life, as it has been cut in half before! I believe it to be two halves of two different cars - was cut through the A piller and right through the middle of the floor and rockers (didn't know that until after I got it home OOPS). Anyhow, the firewall was battered real bad, conceivably from the wreck it was in. I really had no choice but to just cut it out.

Now I'm facing cutting a hole in the firewall to mount a wiper motor. Got caught in the rain on PowerTour - that was NOT fun.
