Watch Cory's car in action.

Greetings all. Chris here again. I have some video of Cory's car in action. Not the greatest since we had the camera mounted to the car and it was shaking. Anyhow, it was fun. Here's the first few. Cory and I are going to develop some sort of home brewed, counter-balanced, gyroscopic camera mount so maybe the next time we shoot some footage, it won't look so <<>>.

I let him add the play-by-plays.

Here are the stills. Can't sleep, anyway.
In the first one, the shiny thing in my teeth is the self-locking nut that holds the linkage bar to the left side Dell. This was after the hill run in Chris' neighborhood, which as luck would have it, was the first run of the day at speed.
The second shot is right after the high-speed run on the interstate, and the third is only about five minutes into the ride, as we decelerated from the three-gears-only clip, above. On that leg, I never got to hit fourth because of the dark-colored SUV ahead of us.

You've done it again, Chris! Thanks!
It should be noted that Chris was on board for the first shakedown-related malfunction. In the first clip, at about the one-minute mark or so, there's a distinct difference in engine noise. That's the part where the linkage connection from the hex-bar to the left carb broke in half and needed replacement. Thanks to Warren Miles, who happened to have exactly the right part on hand, five miles away.
I'm going to have to buy that man dinner.
The other clips are pretty self-ex, except the one where the GPS is placed on the outside of the windscreen. Chris thought it would be a good idea for us to see in real-time what the vast network of satellites clocked us at. At one point, it was 100 mph (clip no. 4); would have been more except for traffic and common sense. I also want to point out, for those among us who haven't driven in the MD/DC/VA region, the rest of the traffic on that stretch of interstate was cruising along at about 70 mph. I got a really, really good idea today of what that little car is capable of. Holeeee ...
There are stills to go with today's rambunctiousness; I'll be putting them up tomorrow.
One of them is a really good shot of the tach and the GPS, with the tach surprisingly low, and the GPS surprisingly high.
WOO-HOO!

The first one in this set is your friendly onboard videographer, Chris. The second is his finest work of the day; the tach reading something around 4,600 rpm at 94.6 mph. And the last one. ... Well, I'm just going to say that the frightfully cold weather in the mid-Atlantic doesn't dampen my spirit one little bit, thanks in large part to the flying helmet/goggles combo and the Luftwaffe jacket.
What a GREAT day for a drive!

I need to congratulate you two!!! These videos are a total blast!!! Cory, that little thing can definitely keep up with traffic!!!!

Those are awesome Cory! You crack me up. I love the mini van and suv in the #4 clip, watching the brake lights go on as you're coming up from behind. I can just hear the people driving them "What in the hell is this thing flying up my ass?!"
It seems you've solved the brake issue, or they finally broke in? I can attest to all those watching - as great as it looks and sounds, it's soooooo much better in person! Great stuff Cory!

Mickey, got your note "I just had a guy in the restaurant come up to me ... ," about the Hoopty. Funny!
Trista and I may be up your way for lunch one of these days, if the weather holds out as long as they say it will.
I'm overdue to head south and see those guys, and I still want Alan to have a turn at the wheel -- if the doctor agrees it's a good idea.
Thanks also, Ricardo. Whenever you're in town again, feel free to hop in and spin it up. Mickey seemed to like it okay, but he didn't rip the throttle very hard.
Now that the brakes are seated correctly, it should just be rapid deceleration that rates being really careful.

Again, anyone in the SOC who wants to drive the Hoopty can have a go at Carlisle. Lane's got first dibs on-site. I just can't keep this to myself -- everybody ought to have a go at least once. It's a blast.

Cory,
Missed your call....damn what a nice day to throttle up!
I am around until 2:00 on Sunday ~Alan

Iffy for Sunday, but Tuesday's wide open. You?

Cory, my brutha!

What a blast to watch those videos. I think the shot of you in full regalia and the Hoopty at speed really captures the spirit of driving these great little cars!

Have fun - you earned it!!

Peace - Out!

Great videos! What kind of engine is that in there?

Mark, that's a 2.3-liter Type IV. Used to be a 1.7-liter case, like the kind you used to find in the VW 412, the Porsche 914 or the VW bus (and who knows what else!).
Glad you liked the videos. Keep checking back for more until it snows in the mid-Atlantic; I'll keep driving until I have ice in my eyes.

Thanks Cory - It sounds amazing!

Cory,

Great videos! Great inspiration!

I thought I remembered reading that you're running a Flowmaster muffler. Do you know the model/part number?

The style I have is quite a bit larger than I've seen in your pics. The Flowmaster techs recommended it because I wanted a two-in, two-out, configuration, but I'd like to see if I can use one like yours. I've got the 2 liter six cyl. 911 engine, so I don't know how much exhaust it pushes compared to your 2.3 because of the typical operating range. My engine being the S model, makes its power in the 3000-7000 rpm range (7300 redline). Though the mechanical injection gives it great throttle response even down lower, I expect the needle will need to spend more time in the upper half of the tach than a built type IV, and I may need more muffler to keep its lungs clear and still sound tolerable. What revs does yours see?

It's hard to tell listening to your videos, but is your exhaust pretty loud (subjective, I know)? I expect that compression ratio also makes a fair difference in loudness and tone, especially with cams that have a lot of overlap. Do you know what compression you

Robert -

It sounds like you're running a 1968 2-liter 911S. In my experience with that engine (I had a '68 S Targa rust bucket) the engine started to hit its power curve around 3800 rpm.

I'm guessing that anything smaller than what you're currently using as a muffler (flowmaster?) will result in 1 of 2 things. The smaller muffler will undoubtedly be MUCH louder (fewer passes) or skew the back pressure necessary for optimum performance of your 911. If you're OK with what you have (muffler performance-wise) stick with it.

Or maybe research a Borla exhaust.

Peace - Out!

Jim,

Thanks for the comments. Those are my concerns as well. There are several good muffler options for larger VW engines, but I just don't know how they will work with my engine.
The engine is actually a 1969 2-liter 911S, not much different than the 1968; a little bigger valves, etc. I thought that the '68 had Weber carbs, though, as opposed to the mechanical fuel injection (MFI) in the '69. The MFI is supposed to be a bit finnicky when it comes to exhaust. Bursch makes a special muffler just for those but I just don't have much room behind the engine where it normally sits.
I have not run the engine yet with the Flowmaster. Flowmaster started out building mufflers for muscle cars. Great sound with great flow. The one I have was designed for the GM cars with the transverse muffler behind the differential (Camaro, etc.) and has the dual inlets on opposite ends of the can; same with the dual outlets. I figured the arrangement would work well with the six and mounted forward of the engine over the tranny. It should flow fine, but it is as big as a factory muffler (but much less expensive). Above the tranny works, but is not the best.
I'm trying to check all options before I start fitting tubing. Maybe I should start a separate thread to see what other folks have done.

Thanks,

Bob

Robert -

You're right about the '68 with Webbers, my bad. I believe you're also right about the exhaust flow characteristics for MFI 911's. There are folks on this site who are light-years more knowledgeable than I on this subject, so I'm sure someone will chime in eventually.

Anyway, once you've decided on the muffler that works best for your ride, take out your pencil and mark April 21-22, 2007 to drive that bad-boy to the Paso Robles SOC meet. I know a lot of SOC fanatics would love to see & hear that 911 in your Speedy. I am also positive you will find it to be a very memorable trip.

Peace - Out!

Jim,

I'll definitely put that on my calendar. I'll likely have to attend without a speedster though. It looks like my weekends for wrenching will be limited again for a few months due to working out of the country. Working for a living isn't a bad thing, it's just inconvenient.

I'll start a new thread asking about 911 mufflers and quit hijacking Cory's thread...unless Cory is interested in spending some winter months in warm Arizona working on someone else's (my) car. As much as he accomplished in the past few months on his, it should be a piece of cake. What do you think Cory? Think warm.... Besides, it would be great experience in case you decide to pursue your 911 engine. Can't blame a guy for a little arm twisting.

Thanks,

Bob

Bob, I went with this muffler because it was on hand already.
I couldn't tell you what the part number is, since it was already hackneyed when I pulled it out of the used parts bin, but I can tell you that the length and height are about 7" each, and it's about 3" thick.
The header is scratch-built of new pipes and old exhaust pieces, with composite-made flanges of hollow tubing welded to 1/4" wall-thickness pipe shaped to the oval ports in my heads.
The muffler is very loud, about 105 db under moderate load (3000 - 32000 rpm) and you need hearing protection to drive it like you stole it.
Think Harley-Davidson.
I hit my power band at about 3,800 rpm. I usually drive in the 3,600 - 4,300 rpm range. There are two features to the exhaust that I countered the flow problem with; one is a cone inserted into the 3" pipe as a mute (like a trumpet's) to quiet it down a little. The other is the plate inside the muffler. It's 3/16" thick, and chevron-shaped, with the point of the chevron toward the inlet side.
I'm not happy with it, but it's what I've got for now.
In addition to Jim's suggestion of a Borla (sp?) muffler, you might look at Bursch or Ansa.
Whatever you come up with, assuming you're still looking around, let me know, please. I'm still looking at installing a 2.0 '69 911E -- if I don't decide to build a Spyder first.
Does that help?

Cory-

It looks like you used a can of 'Spam' as your muffler (did you already use that comparison in a previous thread? - CRS) - I LIKE Spam!

How'd you know? Here's the before picture:

Cory,

You're a funny guy.

Cory, Great shots!1
BUT you really need some gear...

The gearing of your transaxle and those tire sizes are seriously inhibiting the potential of the car.

Going with TIV power you ca gear the car the way a Porsche should be..

I'd like to see you at 92+ MPH @ 4,400 RPM with that cpmbo.

Going taller will make the car fatser all around, the TIV makes more torque and HP and you'll see that with a gear swap..

BTW- You8 can never have a good enough exhaust system on a TIV, extra power and a lot of it will be unlockied there with some current offerings we have..

That looks like a nice DTM, where'd ya get it?? LOL

I got your ecstatic voicemail, by the way!

Thanks, Bob! Try the veal; I'll be here all week -- and don't forget to tip the wait staff!

Jake, do I smell a road trip, or are you coming to Carlisle in the spring (and bringing me a tranny and some pipes)?
Glad to know you got the message.
If you ever need a testimonial ... :)
