Farmboy Posted June 6, 2017 Share Posted June 6, 2017 Here's my rendition of a blown chev 250(ish) straight 6. It took a bit of research but the end result is a believable model. It will go in the front of the Revell Chopped Austin it's sitting in for the mockup. I did use one aftermarket part. It's the throttle return spring on the rear of the blower. I just had it lying around, but the whole engine is a parts box baby with lots of wire, solder, aluminum, homemade belts and bits and pieces. The banjo bolts were made from seed beeds and pin heads. Last thing will be to route the cooling hose on itself from the top out to the bottom in. It's a drag car, no way streetable so no rad required.

mod3l Lover Posted June 6, 2017 Share Posted June 6, 2017 That 6 popper looks awesome like that!! David S. Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted June 6, 2017 Share Posted June 6, 2017 Nice offbeat powerplant setup, and it certainly could have been done that way. Very interesting. Quote Link to comment Share on other sites More sharing options...
Farmboy Posted June 6, 2017 Author Share Posted June 6, 2017 The blower sits on a scratchbuilt intake manifold. I gave it three inlets -- 2 per cylinder --, arranged to give even room for the exhaust manifold pipes I made from a set of v-8 exhausts. each one had a 1/2/1 configuration. I cut them 'mirror' to each other, leaving a 1/2/2/1 configuration and reassembled them. The whole thing fits properly on the engine in the following sequence:. single exhaust - dual intake - dual exhaust - dual intake - dual exhaust - dual intake - single exhaust I will add a single header pipe to the exhaust manifold and end it with a small megaphone in the driver's side wheel well.

chepp Posted June 6, 2017 Share Posted June 6, 2017 That looks good -- it's great to see something different yet believable. Instead of the looped radiator hose, you might want to just make block-off plates to cover the "openings." Quote Link to comment Share on other sites More sharing options...

espo Posted June 6, 2017 Share Posted June 6, 2017 Great idea. I have often thought of something like this just never got around to it. This proves its doable and looks great. Quote Link to comment Share on other sites More sharing options...
Farmboy Posted June 6, 2017 Author Share Posted June 6, 2017 Thanx for the comments everybody. Thought I'd give it a try. I've seen potvin setups but not with a sidemount blower. thought it was time to do one. Quote Link to comment Share on other sites More sharing options...

drsnapper55 Posted June 7, 2017 Share Posted June 7, 2017 Nice job with something really different - I like to see the "out of the box" stuff - thanks for sharing Quote Link to comment Share on other sites More sharing options...
Farmboy Posted June 7, 2017 Author Share Posted June 7, 2017 Mark, inspiration started with a recently bought 40's Plymouth kit with an L Head 6 in it. I didn't know much about the engine and ended up on the H,A.M.B. (Jalopy Journal) for info. Browsing around I found photos of sixes with blowers! I dug around that, links, and other sites till I had enough info to put one together. Actually I still have an old 32 Ford kit I built years ago where I've simply glued a blower on the side of the 6 cylinder block and led two aluminum pipes (think of the Orange Crate) to the 'intake' on the other side, I'll take a pic of it and post it here later.

Farmboy Posted June 7, 2017 Author Share Posted June 7, 2017 Dan, I did a bit of surgery to the front end to adapt. I'll post a pic hopefully tonite. Thanx for the kind words everybody. Quote Link to comment Share on other sites More sharing options...
Farmboy Posted June 7, 2017 Author Share Posted June 7, 2017 Mark, here are a couple of pics of a decade ago attempt to have a blown 6 cylinder, kind of a combination of belt driven/direct Potvin blower style engine. Pretty simple right down to the sideways carbs. I may upgrade it... as always, comments and observations welcome and Dan, here's where the nose sits. I cut the rectangle to fit the engine and pulley length then added some sheet styrene to build the 'wall'. Bodywork is in the rough stage right now...

bisc63 Posted June 10, 2017 Share Posted June 10, 2017 Love it! This idea could work well eith a slant-6, with the blower mounted at an opposing angle to the block for visual balance, putting the injecor stacks thru the hood at an angle - would have a real Tom Daniel-meets-Dave Deal feel to it.

Farmboy Posted June 11, 2017 Author Share Posted June 11, 2017 Rusty, you read my mind. I'm playing with the idea of making a pseudo 225 (is there a kit out there with one?) from a straight 6. The intake manifold looks like a model in itself to make. I do have an extra chevy straight 6, creating a slanted oil pan can't be that tough....

Farmboy Posted June 12, 2017 Author Share Posted June 12, 2017 Nice work Jeff! I have an actual Orange Crate with the Potvin setup in my stash to build. I've been trying to amass accurate info on the fuel supply/surge tank/idle assembly on the blower before starting it but there have been many changes to it over the years. We'll see how it goes. While looking at other Potvin setups, I kept running in to Paxton belt drive superchangers from the 40's and 50's. Looks like a flathead project to me. Again, thanx for the kind words everybody.
