Type 1 conversion

Thanks Chris My goal for the enging was torque only and I actualy hope it falls on its face at around 4000-4500 kind of a revlimiter to keep the wife from doing 80

thats why I used smal exaust and tiny intake and a small cam. I am going to replace the throttle cable after work. The jets will be here tomorrow I am going to start with 60 idles and 1.50 mains and Ill let you know how she runs.

Yeah, we wanted torque too...but I want to get some revs out of it still...I want to try and push 95mph just once, but intend to wait for a forecast of absolutely no wind.

Thank you for all the info, the engine looks great hope I need to start mine to but I also want some power too like Chris, so let me know hoe the test drive goes I like to gte to 100 mph if posible

I almost spit my coffee across the screen.

Don't get me wrong folks I want power too just not the RPM's to go along with it depending on MPH I might put taller gears in the tranny It needs a rebuild anyway. I just dont want to have to spin it @ 6 grand to get power.

I got my but kicked by the throttle cable last night I put in the "late Bay" cable only to find it is 4 inches too short.

so now I have to find the right one. The jets come in today

. I might try and straighten the old cable it has kinks from the type 4 set up that make it bind in the doghouse tube

Dad read that over my shoulder as he headed out the door and said 80 was certainly enough of a handful...but i've seen video of a bus that made it to 124mph (albeit mid engine subaru) with a stock silhouette, though lowered on Porsche rims...and it didn't even seem too sketchy.

We've basically got a `71 trans - pretty fresh too...so if anything I may have to put some taller 15 or maybe even 16" tires on. I might even dyno it later this year at the Everett high school event (no wind resistance

)...for giggles of course, really, who the hell dyno's a bus

Hey, I just got an idea...maybe I can get a picture of the speedo reading ~95 easier if I just put my 18V Dewalt drill on the cable

Post by **Marc** » Tue May 02, 2006 8:04 am

It'd be a lot safer

- you'd be busy enough at that speed without trying to hold a camera in one hand.
...don't know if that'd make it past 60MPH or so, though (you'd need ~1250RPM), and the die grinders only turn clockwise

Back in my younger years (20ish) I had my 73 westy doing some where near 90mph ( too scared/ busy to look at spedo) down I-90 from the summit to North Bend at about 2 AM in March I had a girl friend in Yakima and I would visit and come back waaaay late on sunday to be at work early monday.
Going that fast in a westy

not the same as doing 120 in my 69 bug it added the word IF to my driving.

If I make it down off the hill, if I can stop, if there is no wind gusts, if nothing breaks this fast. if the windshield stops fogging up, if....

So to me any thing over 70 in a bus there are to many IF's

145 Mains and 65 idles with a zero pumpjet 160 air corector that is the new starting point runs much better and cooler still waiting on the throttle cable

hope to get it here by the weekend. I want the highway run to be the cruze for the cure if its ready.

One thing for this conversion is changing drivers side carb Idle jet you got to pull the carb to change the jet due to fanshroud interferance

its tedious to say the least.

will keep posting updates.

The stinger might have to go the wife thinks it sounds like a drag westy.

What did you order? I'm pretty sure I used a `69-`71 cable (211 721 555G) which is only about 5/8" longer than the stock one in your `74 shoulda been.
If the one you were trying was from a `75-`79 FI II it'd be much shorter, ~4-3/4" too short I'd say.

If all else fails you can get it on the road by splicing two cables together over the trans with a couple of barrel nuts...

It is probably the 75-79 one it was labeled late bay and it was about that short

And you read my mind about splicing the cables that was going to be my next idea if bus barn lets me down. just pull the bowden tube off and splice. the only reason I need to change is that the old cable is kinked so bad it dosen't slide through the fan shroud tube. I am trying to do it right so I don't have to do it again but then... the desire to get it on the road might overwhelm that.

HELP I have created a MONSTER

So I am not a really patent guy Thats why I like drag racing who wants to wait 3 hours to find out who won.

Got it dialed in stationary and did the ghetto throttle cable fix tuned it with help of a good friend of mine idles @ 800 rpm CHT with a raytek @ 230 and 226 @ idle ( I wanted lower) timed @ 6 ATDC with a 35 total @ 3200 SVDA dizzy 35 was with vacuum.

The current jets are 65 idle 145 main 160 AC

The Idle jet is good (Mix screws both out 2 1/4)and with out load when the main kicked in @ 2400 I got a tiny puff of black out the stinger and then she took off to 4500.

So I took the test drive and... wholy SH!@#$T it pulls like my Dodge Diese massive TORQUE !!!!

But as I top out the gears (you would think I have a tach with all this, but I don't) it pops through the carbs and it got way hot so to me that means it is lean when it gets on the main under load.

Help I need a reality check what do you folks think I can go up to 165 with my jet kit before I have to start drilling.

I am looking for advice Marc or any body else that has tried to under carb a big engine..

Once it is dialed in it is going to be the westy from hell.

So I am winning the jet wars I have 75 idle and 155 main

and she rips. I went for a drive after I dialed it in and put some timing back in (Thanks Marc) 46 total with vacuum.

The drive was awsome all of my normal test and tune hills that I could only pull in second all but one I could pull in fourth.

it rocked.

I just have some sync bugs to work out (linkage getting tight as it heats up)

CHT was low didn't have the gun but I could touch them and not get cooked same with the exaust (its wrapped)

Put the tin and seal in and will finish the fine tune tommorow It still running a little rich but I want it that way till the break in is done.
I just have a pop through the exaust when it is about to transition from idle to main or I off and on the throttle at around 2500ish

The wife drove it and loved it she thinks it pulls way hard. and was doing 50 in a 25 up a hill that we could only do 20 before.

It tapers off at around 65ish and quits pulling but it will still climb everest @ 60 and It isn't broken in

So tomorow new oil again, valves again, sync again, and then try and figure out my brake lights they craped out I really need to bribe some one to un-hose the frankenstine wiring I have in the engine bay. (i suck at wiring)

For those who might be nervous about the conversion DO IT i wish I had along time ago.

I just finished putting an 80mm VDO in using the Bus Boys Inc. adapter since I don't have a clock - but I put a new CD deck in so it was up for grabs anyway.

I'm thinkin' about putting some 215/60-15's (~25.2") on back and figure 70mph will be ~4000rpm. 95mph (~5600rpm) is seemingly out of reach - didn't balance the bottom-end and have a cast crank.

mightymanx · Post by **mightymanx** » Sat May 06, 2006 10:44 pm

Nice Tach I need to mount one there also I don't have a clock either.

I just got done replacing my brand new 95 amp alt that the pulley shaft snaped and the fan came off

$230 for that piece of crap found out the shaft is warped and it wobbled it self to death in 32 miles. (30 thousandths run out)

By the way if you didn't know changing the alt with the engine in is a PITA.

scrached my pretty paint and dented the fan shroud but I am taking it to cruise for the cure tomorow.

Found out there is not a hill in Kitsap county I can't accelerate up in fourth.

This combo rocks tons of torque I tach out at about 65 but I never slow down either I need taller gears or 6 or so gears.

I will post some pictures soon but not right now its 10:30 pm and I am wasted after installing the high torque starter (needed the regular turns slooooww when its hot) the emergency repairs and being Pissed for dinging and scratching the engine when it has less than 100 miles.
