"Pushrods brand, type, length:  NA"...Hard to find for these engines. .Impressive how well this ran all week.

[Dave427SOHC]

Impressive Jay Congrats!! If you used carbs how much loss do you think you would have

[jayb]

I don't think I'd lose too much horsepower, in fact there are some folks out there who would argue that you would pick up power with the carbs, especially if you used those split Dominators.  But drivability with the carbs would really suck.  Since this engine spends a lot of time on the street, EFI was the way to go.

[Autoholic]

You could break 1000 HP if you just ran a different fuel. Some gas stations around the country sell 101.

So... when will we see you putting a blower on a SOHC? That kinda is the inevitable direction. Instead of going for offset bores in order to increase the displacement, you could just plunk a 8-71 on it and open up a whole new chapter.

[jayb]

I have a twin turbo SOHC in the works, but its probably a year or so off yet.  One issue is that I don't want to put the funny car style cage in any of my cars.  I like being able to get in and out of the cars without crawling through a roll cage; they are street cars, after all.  I can run pretty close to the limit of my cage (8.50) with the naturally aspirated engine, and so going with the blower in that car would just make me NHRA-illegal.

I plan to put the turbo engine in my Galaxie, and probably run right on 8.50 with that car as well.  It could run a lot faster, but I want to keep my bench seat, column shift, full size Ford the way it is with the normal cage and removable side bars.  It will never win at Drag Week (all of the power adder classes are running faster than 8.50), but it will still be pretty cool...

[machoneman]

Wow, a twin turbo! Cool!

But, if I may be so bold, and considering it's in your Galaxie, why not say a 8-71 Jimmy blower on top w/ a cool Hilborn/Enderle hat (converted to EFI)?

Sure, the twin turbo is cool yet the bulk of it is hidden under the hood, ideal for the Shelby with the strut front end and you could likely put back on the stock appearing and rather unique hood.

The Galaxie would look mighty cool with a polished blower, eh?   See 385 series '64 below......

I tend to agree, Bob, the SOHC deserves a blower.  But I already bought the turbos, and I like the idea of everything hiding under the hood.  Actually, in the car I'm going to put the turbos and air to water intercoolers in the trunk, to avoid all that piping that you normally see in a turbo installation.  There's just going to be one tube coming through the firewall and into the back of the intake manifold, so that nothing will be present to spoil the looks of the SOHC. 

[machoneman]

Hey, we're all going to love it no matter!

Ah, but someday......blower heaven,here we come! LOL

[Heo]

Jay That Will be an instalation similar to a
Thunderbolt fighter

[57 lima bean]

Are you going to cut up one of the manifolds you have now that seems to be hiding shop light from the shelves or start anew?

[jayb]

Jay That Will be an instalation similar to a
Thunderbolt fighter

Exactly, Heo, same idea.  At Drag Week in 2006 there was a guy with a late model Crown Victoria that had two turbos parked under the car in the back.  A really, really cool installation, and I'm going to try to do the same basic thing.

[jayb]

Are you going to cut up one of the manifolds you have now that seems to be hiding shop light from the shelves or start anew?

Steve, don't you recognize priceless works of art when you see them?  Those manifolds are eclectic montages of dinged up aluminum tube, welding slag, JB Weld, and RTV; how could I ever cut one up?

I'll probably start new, mostly because I need to build the manifold to fit under a factory teardrop hood, and to position the inlet facing the rear and down, to take the big 4" tube bringing the boost out of the firewall...

[Autoholic]

As long as you're happy with an increase in turbo lag.

[Heo]

There was Someone in Sweden with
A smal Opel with some BrandX Engine
That had same kind of instalation
You saw the turbos from behind
I saw it in a magazine some years ago
The owner Said it Worked realy god
