New 2332 cc

your just lucky, your using the anti-shocker now right, that and you dont do burnouts, one slip of the foot off the clutch and your likely going to snap that mainshaft....

No anti shocker yet, it's still sitting on my bench, I never got a tap the proper size.. I have over 80 launches on slicks  so far, not wanting to break is the reason why I keep 25 and 28 psi in my slicks too,   I have noticed that even with this much pressure, it seems the only times I have spun is because there is water on the track.  These 5 1/2" tires stick very well.  I have had this tranny since 2001 and well over 300 launches, mind you most of them with street tires on ...preload, preload, preload keeps everything happy, and I tap my dash 3 times before every pass ....NOT !!!!..I am waiting for it to go boom..crunch...grind...on every pass, but it keeps surprising me.

Yup just lucky I guess.

your clutch disc will always be dragging in the direction of rotation even with the clutch pedal to the floor .dont think that when the clutch is depressed there is zero contact between the flywheel and disc or pressure plate and disc ..the term preload is not do to the fact you are putting some form of tension in the driveline it has to do with all the slack being taken out of every component required to move forward ,so that when the clutch is engaged there is no slack to be taken up which could result in a premature falure.

when you do a burnout for the reason of heating the slicks to gain traction and launch hard enough with enough torque behind it from a large motor to pull and carry the frt wheels its a matter of time before there will be a falure of some type .take a look at some of alans wheel stands and 1.5 zone 60' that is huge stress on the trans .

my current trans has had easy over a 100 passes with large burnouts as well as launching on the bottle .i would say i got more than fare value out of that ring . there is no way a stock trans would of taken 10% of that abuse.

I think its a single side plate irs He's got , so it has the 3.78 ("super beetle")1st  and the 3rd & 4th gears with integral syncro hubs so they wont spin off.  He'll blow the spider gears or cv's first

[Billyisgr8]

yup... its a ssc irs with a stock diff made into a superdiff.  Hoping the cv's do blow first, thats why I kept them T1 instead of switching them out to the thing axles, cv's, stub axles and output flanges I have here.

I was fortunate to pick up some SAW short swing axles from C1 several years ago...back when they were considered almost bullet-proof.  Apparently the newer SAW versions have been produced off-shore and are not as reliable.

Here's my best time slip from Edmonton.  Still have some work to do on the 60' and learning to shifts at higher rpms...it's difficult to change after 30 years of shifting by ear

Going to lighten the Beetle a bit and maybe increase the .550" valve lift to .580"...probably have to notch the pistons, as it's close already:

[Billyisgr8]

Nice to get out one last time Neil, Thats a good #.   Let me know if you are going to Vernon anytime, you can stop in for a visit.

Kevin

[Bruce]

You in Vernon, Kev?  Thought you were in Sicamous or SA?

[Billyisgr8]

I am in Sicamous...Neils parents are in Vernon...or maybe they were in Kelowna.  He would be driving through though.

now is the time to spray it

Jim,

I may just do that  It's crazy how many people come up to me at the tracks and tell me that I should put nitrous on this motor for the finishing touch! One Volvo mechanic in Calgary has offered to get me a complete kit, with spacers that go between the manifolds and IDA's...he calls it a complete bolt-on kit.  However, I haven't done any research at all yet, so it's too early.  I'd appreciate any suggestions

I'm really happy with how the Beetle drives...it always runs straight as an arrow, with no sign of instability, so it could probably run in the 11's and still be safe.

We still might have another couple weeks of racing in Calgary, according to the track website, but after that I'll have some thinking to do for next season.  Probably will put the original 1500 cc back in for the winter

[neil68]

Has anyone tried a Web 226?  I found a "stroker clearanced" 226 on the internet, so I'm going to give it a try:

278 degrees at 0.050" and 0.569" lift with my 1.4 rockers

The Web 226 appears to be the same as a CB 2298 (278/.570"), and just a hair bigger than an FK 87 (276/.561")...might have to notch the pistons this time.

[neil68]

Well, I finally got working on the camshaft swap...decided to try the Web 226 next.  Checked the lift today and got 0.570" at full lift with Scat 1.4 rockers.  Had to switch from the Manton 0.035"-wall pushrods, as a couple of them bent last season...installed some 0.058"-wall Manton's this time; they are heavier but hopefully more durable.  I have only found two people on all the ACVW forums who had ever used the 226 (I'm sure there are more, but most either use the 86C or 251).  Here is the spec sheet:

[Billyisgr8]

Thats a good street cam        It will be intresting to see what the difference is in power.   Kevin

[jim martin]

thats no street cam that a 3/4 race cam .lol
thats got more running duration than the 86 c .hope you changed your gearing .

if you wanted more lift and a shorter duration i'm sure the new line of engle cams may work also .
another good option would be a web 86 b or engle fk 8 with 1.5 rockers

not sure what you have for valve springs but would recomend erco tripples

[neil68]

Jim,

Here's my new Rancho gearbox setup:  3.875 with 3.78/2.26/1.65/1.31

How do you think that will match up with the new cam?

Had 180 HP at the wheels last year with the 86C.

Here's my new Rancho gearbox setup:  3.875 with 3.78/2.26/1.65/1.31

Ooops, you shoulda gone for a 4.11/2.47 mainshaft.  You need at least 200hp to pull a 3.78 on a 3.88 R&P out of the hole.

[neil68]

I spoke with two of the Rancho staff, and that is what we came up with for gears.

This gearing did finally get me into the twelves, at the end of last season, but the 60' times are still the same as with the other tranny...

[Bruce]

.... but the 60' times are still the same as with the other tranny...

That's because you don't have enough hp to pull it out of the hole.
There's one way to fix your car.  Make more HP!

see even Bruce agree's SPRAY IT

[Darren]

Or make the car lighter... easier on the drive train...
