Lickity Split

[hotstreetvw]

It took me a while, OK, but I've accepted the fact, I'm the guinea pig.  I am powerless over VWs, or maybe obsessed with powerful VWs.  

I didn't give the triple groove valves a second thought.  I ordered a set of race master valves, along with the CB locks (this stuff looks like repackaged Manley, can anyone confirm?).  I'll have the local shop, Painters Grinding, check the valves and cut the heads for 54cc, to put it at 11.6:1 compression.  I'm going to run it on 110, but give E85 a chance.  We have e85 local, so it would be awesome to be able to run it on the street and keep the engine cool.

Has anyone seen the Jaycee/CB IDA Float level gauge?

Couldn't something similar be done to allow for more fuel in the bowl for these E85 applications that require a ton of fuel?

[hotstreetvw]

Couple other things.

I secured a set of Bugpack Super Flow intakes, they need a little massaging to work with the 51.5" Jaycees.
Wasp Stage 3 + stinger, on its way from Germany
Geer's is working on CP pistons and a set of cylinders
Cam is getting ground,  278 degrees @ .050, .430" lift at the cam.

I'm hoping to have this together in the next few months for the start of the race season.

Anyone want to take a guess how much power this engine will make?

I wasn't trying to bust your balls; it's just the reality of how unique your combo is. I found that the folks with experience with roller cams were experienced with high-end drag race engines, but not street engines; not milder cam shafts; not smaller valves; and not lifters that would last for thousands of miles. This generally means you really have to do your homework, or be ready to deal with the consequences from somebody's well-intended but incorrect advice. As long as you've accepted that fact, your mindset going into dealing with failures will be more objective...you'll learn and develop your engine combo (rather than burn bridges with blame when parts fail...because parts will fail).

I know that feeling, but when it all works its the shit

Wait, I thought this was a high-end drag race engine?   I will get it figured out with yall's help.  I'm a little concerned with my current 1.5 Pauters with the spring pressure that is required.  I'm going to give them a shot, but I fully expect to break them.

I sold my single cab this weekend, so I'm fully committed (funded) to getting this engine completed for the spring.  Any questimates on HP corrected to sea level?  Ball park 260-270hp flywheel?

[hotstreetvw]

Richie,

How is your 4" engine coming?  I haven't seen any updates in a while. 

I might need some advice from you on setting up a NOS fogger kit.  A 50-100 shot might be in the future.

Sorry, my mistake...it sounds like a perfectly streetable engine to me

Car is in USA and I am in England

[hotstreetvw]

That gives me a little time to catch back up.

Until about an hour ago, just landed for 3 weeks progress   Waiting on header parts to arrive now


cheers Richie

[hotstreetvw]

I guess I better step it up.  Where is the USW race this year?

Fontana I think in october

[hotstreetvw]

993 miles.  You guys have it good.  A 15 hour drive will put some stress on my marriage.

Its about 7000 for me

[Chip]

Vegas was perfect for me. Fontana is to far to bring my pocket knife this year 

[hotstreetvw]

Valves and locks arrived last night.  I mocked up an intake and it measures 1.856" spring height.  I hope they are all this close.  Slap a set of .060 shims in and call it 1.800".  300lbs installed, estimated 670lbs on the nose.

I asked my wife about Fontana.  Google says 15 hours.  Add some additional time for family stops, we are looking at an 18 hour day.  That would be tough on the family.  It would be a lot of fun though.  USW requires a passenger seat, but doesn't say anything about it being upholstered eh?

[hotstreetvw]

One more!

[hotstreetvw]

About 5 hours under the hood and on the peddle.  This should let me open those intakes up to 51.5 and create a nice taper down into the port.

[BeetleBug]

Very nice. Job well done!

-BB-

[hotstreetvw]

Thanks, the excitement is building.

The heads are at Painters in Denver getting flycut (45cc) and the springs installed.  Plan is zero deck, .050 copper gasket.  I'm guessing the valve pockets will be 5-6cc.  So 12.3-12.1 : 1 compression.

Before taking the heads, while the valves were out, I was able to match up the intakes to the heads nicely.  My compressor is down (tank check valve) and I had to borrow a neighbors.  Going from 18cfm to 5cfm takes patience   The intakes took some work to get opened up, the heads took just a little bit to blend in.  My compressor should be fixed in the next couple days and I will start opening the intakes up on the carb end.

STF Engine is nearly complete.  Had to shelve to the turbo stuff since I am on path to finish the 4" engine.  Its been a busy winter and I haven't made as much progress and don't have the time to get a FI install done before the season starts.

I am rerunning the FK45 with CB 1.4 rockers.  Lift measured at .570" @ the valve.  I bumped the compression to 11:1.  It needs a header and pushrods and it will be ready to go back in the car.  The track opens April 15/16/17, and I am hoping to drive the car to the Painters Grinding Dub Roast April 16th.

I'm hoping with the freshening up (valve job, new springs, new P&C), more compression, IDAs, 1-3/4" header, it will improve on my best of 13.66 @ Bandimere.  Maybe a high 12?

[andy198712]

Just caught up a couple pages on this. great thread!
going back to waste gates, i learnt last night about installing WG's on the exhaust housing which if you can fit it in would be ideal with a header like ours have....? just a thought

[hotstreetvw]

Thanks Andy.  I think getting the wastegate on the exhaust housing would be difficult.  the downpipe is already going to need a sharp 90 degree bend to clear the bumper mount / quarter panel area.  I was planning a remote wastegate.  I think TurboBob runs a remove gate with a long tube from the collector to the gate.  Seems to work OK for him.

Here it is, ready to mock up deck height and get the cylinders cut.  TF-1 doesn't include case studs, so I pulled studs from a old mag case that had serious corrosion.

[modnrod]

Nice table.

[hotstreetvw]

Ha, yeah the wife was happy about my photo shoot.

Nice table.

[Sam K]

I love your car! I've been watching your build thread for a while now and hoping I would run into you eventually at a local show as I live in Westminster. I usually go the Painter's Dub Roast but my wife made plans for that weekend.

[hotstreetvw]

Thanks.  I am planning on taking the car to the dub roast.  It might not be street legal for then so I might pull the car down on the trailer, unload close and drive it in.  I will also be at the track that weekend, most likely Sunday.

[Sam K]

I was planning on going to the track on Sunday too but it looks like I'll have to wait until the next weekend.

[hotstreetvw]

CSP/JPM Wasp.  Starts at 1-3/4", step to 2", step to 2-1/8".   It is a work of ART.

[hotstreetvw]

"STF" 2275 is in the car and running.  Hell if I can call it STF anymore, damn thing cost $$.

I changed the fuel pressure regulator from the chrome holley dead head type to an Aeromotive X1 in preparation of the big engine.  While I was building the pan I had installed two 3/8" stainless lines, so running a bypass regulator was an easy task.  The fuel pressure holds steady at 3lbs with the holley red pump.  The X1 is also the first regulator that Aeromotive makes that you can swap out the spring/diaphragm and convert it to 35-75psi for FI (conversion cost is about 60$).

I've taken it for a short drive down the street, but I haven't been able to get after it.  It does feel stronger than it did last year and responds to throttle changes quicker.  The jet stack is currently 70/120 idles, 175/200 main/air.  I tried 60s for idles and even though I could get it to idle fine, it had a huge flat spot while driving.  There is a lot of contradictory stuff on the internet about jetting for elevation.

I am still planning on upgrading the exhaust to a 1-3/4" large flange with a stinger.  I'll be ready for the track Sunday either way.
