Lickity Split

[hotstreetvw]

With axles all the way forward in the spring plates, it stared at
.50 degrees in on rear driver
.22 degrees in on rear passenger

I was pretty happy with these figures considering I narrowed the torsion housing and all of the suspension stuff I've done.

Finished at .12 degrees each side, totaling .24 toe in, about a 1/16" total toe in.

Front was wayyyy off, don't even want to talk about it

Finished at .24 tie in.  I need to recheck the shims because the camber didn't match too well.

Very cool project, thanks for sharing!

Very cool project, thanks for sharing!

Thanks, it's been a fun project.  Winter is about to be here so it will start slowing down, maybe some work on the big engine over winter though.

I am headed to the track tomorrow evening for a little test and tune.  I'm worried the clutch isn't going to hold but will give it my best.

Elevation!!  Do I start making the excuses now?

Well let's just say it goes straight.  

Bandimere is at 5800', density altitude was 8000', but it was a beautiful day.  I did get to weigh this pig, 1865 lbs w/ driver....

First pass, let's go easy on it, belt and muffler.  I lifted and just tested the stability.  This car hasn't gone over 30mph in 30 years.
R/T .310
60' 2.233
1/8 10.302 @ 62.92 mph
1/4 16.769 @ 72.87 mph

Second pass, ditch the belt, w/ muffler. Had issues with the two step, I was on the launch limiter while running through the gears.  Maybe I'm not all of the way out of the clutch and it's still engaging.  Needs investigating.
R/T .396
60' 2.120
1/8 9.277 @ 77.05 mph
1/4 14.598 @ 94.56 mph

Third pass, no belt, w/ muffler.  Didn't arm the two step, launched hard, didn't nose over as bad.  Still bogged though.
R/T .141
60' 1.891
1/8 8.804 @ 77.90mph
1/4 13.891 @ 96.29 mph

Forth and final pass, no belt, w/ muffler, no two step.  Hit the limiter on a shift, gave up a little mph.
R/T  .110
60' 1.885
1/8 8.751 @ 77.91 mph
1/4 13.86 @ 95.52

I need more seat time, and a better understanding of the best shift points.  I need a diet.  I need to work on the launch.  There has to be a 1.6 in there with slicks, the 3.88 and 4.12 first.  Btw this was my first time down the track in 15 years.  My boys had a blast

Video of the last pass.  Any feedback?  I can't tell if I'm spinning.  Too much compression, not enough? I have adjustable shocks. I want to hang the tires in Vegas!

Great results!

What are your plans with the paint? I love it how it looks right know 

[hotstreetvw]

Plan is to leave the paint for at least the next year.  Over winter I will fix the bumper bracket areas that are jacked in the rear and replace the apron (removable).  I need front fenders.  The plan was to get split fenders from gerson, but he does them in limited quantities and the next batch isn't until Q1 2016.  Once I get the parts together, it's unlikely I can have it painted before race season starts.

Ideally we will go to phx while there is still snow on the ground here, make a trip to California for the classic, do the colorado bug in, and do Vegas end of the year.  Sprinkle a bunch of test days out at bandimere.

Then maybe next winter pull it down for paint.

[richie]

Well done for getting it done and taking it to the track   NHRA gives a correction factor for that 5800 at Denver that makes your time 13.02@100.89, the fact that it was 8000 makes it even better, we will be in Vegas so I will come over and say Hi

cheers Richie

[hotstreetvw]

Thanks Richie, I look forward to meeting you in Vegas.

Any recommendations on launch rpm?  I was leaving at 5000 on the two step and it bogged hard.  When I had the two step off, I was feathering the throttle between 5500-6000, didn't seem to bog as hard and netted the better 60' times, still had a significant rpm drop as can be seen in the video.  What I've read today is 6800 plus with the two step.

I like to start at 6800 and see how it works then adjust from there if needed, vegas you shouldn't need a burnout even or it will bog bad, let it spin the tyre then adjust tyre pressure down to get it to hook

Glad to hear it made it to the track! I'll be in Vegas as well and look forward to checking it out! Still trying to decide whether or not to haul my pile down there to run with Mr. Richie and the other USW boys. Have a safe trip!

Come on Chip bring it and join in the fun

[Chip]

The car looked good today! Looks like you managed to go rounds as well. Now get that big motor together this winter!

[hotstreetvw]

Thanks, we had a good time.



We met Jack from Jaycee and he brought along a couple toys.  The Italian ladies got a make over.





Yeah I went rounds managed to get a win in the first by .005 seconds, only because the fella I raced back out of it but wasn't able to hang on.  The second round was a buy in which I managed to miss second, haha straight to the final.  Lost in the final with a red light.  I can't really claim any sort of victory other than maybe the car survived, but I'll still cash the bugorama check.

Best run was 13.46@99.68?  Had one pass break a 100mph.  Farted around with jetting, couldn't remember to hit record on the wide and 5 of 6 runs.  The one time I did record I turned the car off to replace the belt, forgot to end recording, corrupted the data.  I need to get my shit together.

I had fixed the clutch switch, only to find it getting stuck again.  Killed me on one run when I dropped launch rpm to 5000.  I'm determined to make this work.

The car squats bad, bad bad.  With the narrowed torsion, I don't think 28s are enough.  I had the shocks wound up to 16 clicks on compression.   It's still hitting the tires hard and the tires are rubbing on the inner fenders, no wheel spin, bogs hard  I had 16psi in the slicks, no burn out.  I didn't have a pump, but I'll try 18psi next time, maybe 20psi.

This coming weekend is the last TNT at Bandimere for the season.  I plan on spending the full day out Saturday trying to get my shit together.

Favorite comment from the tower. "The red, gray, black, green bug...........................(long silence).........I like it". ROTFLMAO

Most people thought it was a fake split.  Had a couple guys figure it out and asked if the purists shared some hate for me.  If they feel I've done the car an injustice, pony up the dough, buy it from me, and do it "right".  Most cant imagine the cost of split correct parts.  At least it's not buried in a old shop anymore and is getting driven, right?  I think it was the only split in Vegas, pretty cool.

Overall, I'm happy with the event.  My last real VW race was 15 years ago in Vegas.  I met the goal I set out for myself last year.

[BeetleBug]

Excellent update! Thank you for sharing. And congrats with reaching your goal with great margin.

I have a super simple clutch switch setup for my 2 step. Works really well, allows for good r&p preload while still on the limiter. The video is not as clear as I would like it to be, but hopefully you get the idea.

[hotstreetvw]

I might try that Chip.  Mine is currently behind the clutch pedal and integrated into the adjustable stop plate.  I notched the stop tab so the switch lever arm pokes through.  It worked great but I was riding the clutch so always on the two step.  It's a tricky cat to skin.  Switch needs to be on but allow for some movement of the pedal to preload, but not on too soon like it originally had it.

I've heard of guys staging with the line lock.  If I started staging that way, I could wire it through the same switch.

[richie]

I have a 1st gear switch on mine as well, that way it can only activate in 1st gear or on E brake if I stage using that

cheers Richie

[Chip]

I know mine is throttle position based, and might even have an minimum mph requirement to be active. I've never had it cause an issue either way though.

[hotstreetvw]

I think I've got the clutch switch sorted out.  It's mounted on the clutch/brake pedal stop plate, the one that is secured by a single bolt through the pan.  Since it's a single bolt, it was allowing the plate to rotate, to the point the switch was between the clutch and brake stop tabs.  The two spot welds on the threaded plate on the pan were broken.  I pulled it apart and welded a bolt to the stop plate, then bolted through the floor, cranked on it pretty tight so it's unlikely to go anywhere.

Did a couple practice launches in the street using the line lock.  Felt ok, seems like I was getting more clutch slip.  I added 15mm wheel spacers so the tires stop rubbing on the inner fenders on launch, guess that could have scrubbed a little power off on launch.

Track day Saturday.  My goal is to improve to the 13.4x mark at altitude.  Seat time and minor tweaks may add up.

[hotstreetvw]

New best at Bandimere
13.660@97.46mph
1.843 60'

[hotstreetvw]

To keep my mind busy while waiting on parts for the 4" engine (still waiting on the case to get thrust installed), I've decided to throw together a "sweep the floor" engine.

So far I have...
Mexican AS41 case, std line bore and thrust.  I tapped it for full flow tonight.  Needs a line bore to .020", opened for 94s and stroke clearance.
DMS welded 82mm crank, .010" mains, std rods.  Needs to be turned.
Mahle 94 B pistons and cylinders, need rings
Webcam 121/125 w/ matching lifters, chromoly push rods and 1.1 rockers on solid shafts
30mm pump
Race Trim copy sump
Santana pulley
009 w/module, coil, plug wires
Engine tin

Parts needed
Bearings
Rods
Flywheel
Heads

How would the 121/125 work in a turbo motor?  I've got a t3 turbo from a svo mustang, 60 compressor, .63 turbine.  Needs a rebuild kit.

[Chip]

That cam will kill stock mag lifter bores. I've heard good things about the power and drivability, but I know of 3 motors that had it that all had lifter bores wiped out.

[hotstreetvw]

I've heard it will kill the case.  Any idea if the wear can be repaired later by sleeving the bores?  It's the only cam I have on the shelve and buying a cam/lifters/rockers is out of the question for this STF engine.  I'm just trying to throw something together cheap and abuse the piss out if it.

What do you think of that cam with a turbo?

I'm tempted to pull the AJ heads off my 2275 and have a valve job, then spend some money in the spring for better heads for that motor.  I might do the same with the scat rods.

[hotstreetvw]

OMFnG, lets do this.  I'm going to start this weekend with a light deburr of the case.

Hahaha! Gets like that doesn't it?
Cool thread btw, always looking in.

GID - Get It Done! VERY cool. I look forward to reading your updates. A proper winter warmer engine thread.

[hotstreetvw]

Yes it does! 

I think I contacted Todd about this time last year when I was making the decision for go 4".  And contacted him about every month thereafter to get updates on how the castings were coming, eventually to the machining, then eventually shipping to Geers.  Todd has been very helpful throughout this process.  The thrust and roller setup Geers did looks awesome.  I'll try to get some detailed pictures before I start the debur process.

Pictures of TF-1 as promised




Full flow setup


Case is built for external pressure regulation


Where the front pressure relief valve would've, not included on 4" case


No oil cooler on 4" cases

[hotstreetvw]

I spent about three hours today using a small hobby file breaking edges, on one half of the case.  The machined edges were very sharp.  I also took my die grinder with a 80 grit cylinder and knocked down some of the internal casting.  I plan on continuing this but need for cones/cylinders.

What level do guys take it to on the internal polish?  Grit?
