Will do!

might be hard to get it to idle at 900.... Maybe with the Q jet..

lol (the cam makes this hard....)

[Andyrew]

oook.. So dad messes with the dizzy while I kept the throttle running, then we set the idle.. We'll see how that does on the vacume guage.

Went for a drive and well... sucked.
Ya, its got good power... but about 100 hp of it... (or so it feels)

Well while dad was giving it full throttle, we must have hit a bump or something.. A couple loud noises came... Not continual.. just a couple. Im guessing dad put the clutch in... So we drove it back home (all of about 100 yards) and looked at it.. We looked around, checked underneith.. I tried to point out the low clearance between the alternator belt and the shift linkage (bout 1/4 to 1/8 in...) when dad noticed something...

The trani mounts...

[dan10101]

But I didnt even show you the mount!!

I'd love to talk! Cant say it here? Need more room? More idea's? Go ahead and shoot me a pm (either account..)

Heres the mount... I THINK I have it in backwards (I debated on that for a LONG time installing it... guess I just did it wrong.... Eh I'll figure that one out.

hehe, ya, I cut the tip of the exhaust off... It was hitting... and it was quiet... now my quarter pannel gets warm.. lol

[skline]

Dude, that aint right. It should fit perfect, that looks like its going to fall out. You need to fix that right away. Trust me, you dont want to take any chances with that one. Did you see this???

[Andyrew]

Oh, I know its not right... notice that I posted pics on it and such? lol

Ya, Im going to fix it before I drive it again.. the trani is being supported by a small jack right now just in case.

Andrew

[Andyrew]

Would it be the reason for my engine problems possibly??

[PatW]

We have both a holley and a Qjet. Both seem to act about the same.

You may want to take a close look at your carb gasket. It might be interfearing with the butterflys. (IMG:style_emoticons/default/unsure.gif)

Also look into using a thick gasket if you not already using one. They tend to insulate the heat from cooking your carb. (IMG:style_emoticons/default/idea.gif)

Sounds like timing too.

Go to bed, I will take pictures of mine tomorrow and post them. Also, it is a very possible that it could hold you back, the trans could be binding and causing it to twist and bind which would hold it back, you are lucky you have not broken anything.

[John2kx]

Attached are a couple of pics of how the trans. mount is supposed to look. This is a combination of the 911 sport mount, a notched washer from the stock 914 mount and Rengade's spacer.

Getting the timing right can be challanging with the v8 installed. You may have the distributor installed off a tooth or two but you should still have more power than described. With my timing set correctly, I could still rotate the distributor 3/8" in either direction without loosing the amount of power you describe (3/8" measured by marking base of dist. and having a fixed mark where it slides into intake).

I'd somehow verify the secondaries are opening with a device that indicates movement while your on the road. I don't have this device exactly figured out but had visions of a pen attached to secondary that would mark a fixed piece of paper?????? Maybe Dad could be talked into looking at the secondaries with the targa removed while your driving : )

Good luck,

John

Not the best pic of how to connect hoses to a Holley but all I have.

The three hoses connected to carb are as follows:

Large, medium and small........viewed left to right

Large goes to PCV on valve cover.

Medium is self explanatory (carb to carb connection)

Small hose is connected to vacumm advance on dist.

John

[John2kx]

sorry.......did not attach

[dan10101]

Maybe Dad could be talked into looking at the secondaries with the targa removed while your driving : )

Dad does not want to have his head over the carb while the car is running... lol

[Andyrew]

Thanks all.. Thanks John for the pics, I'll see what I can do about the mounts. In what order did you install the mounts? Trani to adapter to body?

I'll try the holley as well with those hose attachments, I dont think we had them all like that.

Andrew

[John2kx]

In what order did you install the mounts? Trani to adapter to body?

Don't think this is critical but I installed the sport mounts firmly, then installed the remaining pieces loose. With the engine beam mounting bolts loose, I positioned engine fore/aft, left right until the large bolts that go through tranny ear were lined up, ie, no binding fore/aft or side to side. Then tighten everything up. Don't be surprised if you have to make a clutch cable or shift linkage adjustment if the engine is moved fore or aft. Never had the tranny move in two years of operation using this method.

Do pay attention to where washers are installed or ommited as compared to your setup, and the size and thickness used. (there has to be a good footprint between rubber and metal for this setup to work right). Installed correctly, you will keep everything in place when you squeeze the power on.

John

[soloracer]

I was considering using solid tranny mounts. Do you foresee any problems going this way? (Ie: cracking of chassis, etc.) Since my car will be mainly used for track events I'm not really worried about any vibration that might be transferred to the driver.

[John2kx]

Sorry, I'm no expert on what to use for a track car. Maybe Brad will jump in here and provide some useful information.

John

[Andyrew]

Brad hasnt said anything yet... period..

I figure he's ignoring this thread (IMG:style_emoticons/default/laugh.gif)


Anyways.. I fixed the mounts, and I think I got it in right... I think what happened was that we hit a bump and the trani shifted... Since I didnt have them in correctly it just moved...

Sooooo I drove it, gave it a little throttle, and WAM it seems very responsive to me! I maybe gave it 1/4 throttle... I was only going around the block so there wasnt much I could do...

Sooooo With a big thumbs up I decide to let dad drive it.. Well he waited to give it ANY gas (IMG:style_emoticons/default/mad.gif) ... So when he finally gets on it, he floors it.. Ehh.. still slow.. but wait, he's franticly reaching over and I hear a little rrRRRR as the clutch goes in and he shuts it off... "Great, Another throttle cable broke.... grrrrr" thinks I... Well the throttle cable didnt break, and but there was a washer that was holding the secondary's on the Q jet open... take it out and dad says he thinks thats it...

We checked the trani bolts (I marked em with a black marker) and there fine.

We went out again, nope, still no power... At this point, I've just about thrown a fit... I get my hopes up and WAM get shot down AGAIN!!! So dad drives it around more, longest trip... Driving around its about 185-170.. get home.. shut it off.. and in 2 mins the engine is at 230.... radiator is cool.. so keeping the fan on just doesnt make sense.. but hey, we leave the fan on anyways every time we shut the car off. So I just get even more angry... this happens EVERY TIME. 40 degree increase in temp when the car gets shut off? And I bet when If I start it it will jump RIGHT back down to 190 (like it did last night....) I need a little bigger reserve/overflow tank because when the engine shuts off, the water just expands, and the pressure builds and it just goes right out the overflow thing on the cap and fills up the tank.... I had maybe one cup of air left in that overflow tank.... I Think I need a bigger one... lol. And a higher pressure cap (what, 16-18lbs isnt enough? SHEESH)

So problems... (summary...)

No power still

battery ground cable broke on the tightening end.. need to get another one of those.. grrrrrrrrrrrrrrrrrrr (causes many problems...

overheat 40 degree increase when engine shuts off

Me getting frustrated.. angry... tired.. lack of hope
