VW type 4 engine (turbo'd):
original type 4 case (alu);
original type 4 crank (66mm, 1700 crank), non-counterweighted;
original type 4 rods with arp bolts, shot-peened;
original type 4 head castings, just larger valves (46x40), no welding;
Okrasa cylinders 103mm alu-nikasil, JE custom pistons
CB650 springs, Bugpack Ti retainers, Berg chro-mo push rods.
[Edit]: forgot to add, cam is Web163 on 114 LC [/edit]
EFI with a large intercooler.
Dry-sump oiling.
and some other things 
It made 403 crank hp (345 at the wheels) on a GT3076R turbo:
but with an even larger turbo it now makes 400 at the wheels (~460 crank hp) but with a more turbo-lag. Extra umph is worth it though 
Did 11.4 at 120 mph on the old hp setting in my very heavy 1303 bug. It is build for the circuit though, hence the weight (~2100-2200lbs without me).
Porsche 5-speed G50 transmission with Kennedy 9" dual disk black magics and a 996GT3 LSD.
This is what it does best:
I have beaten the sh*t out of her for 3 full seasons of drag and circuit racing now, also did high speed (135-140 mph) runs on the german Autobahn and it still hasn't lost a single hp yet.
It has proven itself to me beyond expectation tbh.

Here are the specs on my street cars engine.
2387cc
CB #2300 cam
CB 1.4 rockers
CB 86mm crank
CB lightweight flywheel
CB 28mm lightweight lifters
Wiseco pistons with 1mmx1mmx2.8mm wring set
CB 30mm keyed oil pump
CB Magnesium case, modified for side outlet full flow, 10mm case savers
CB 5.500 H beam race rods
CB 4qt oil sump
CB 10mm chromoly head studs
CB 46x37 ultra wedgeport heads, stainless valves, vw-650 springs, ti ret
11-1 compression
CB Magna F/S efi system, crank triggered, sequential fuel and spark
CB 1-3/4 stainless header with stainless muffler
6" sand seal power pulley
Manton dual taper push rods
JayCee billet push rod tubes
Best E.T on DOT M&H tires is 11.89 @111mph. It spun the tires pretty hard because I had 19 psi in the tires not wanting to brake the trans. I drive this car to work, take the kids to school and around town. I do not consider it a long distance driver, more of a hot rod around town and short distance driver. Trans is geared way to low for highway driving, 4.12 R/P with a 1.21 4th gear. It drives like a stocker until you put your foot in it. The efi ECU has an internal two step and I have a line lock installed. Pretty fun to put it on the two step at a stop light. I have a short vid testing the two step on our CB face book page. |

It has 9.8.1 Compression. Runs cool and is very linear in it power. This Refutes all the Nay Sayers about running a 300+ duration cam on the street. The Webers are jetted - 55 idles, 155 Mains, F11 Tubes and 200 Airs. It has plenty of torque without having to rev it a lot to get it going from a stand still. It is very smooth actually. It also revs very well. I can go as high as Shifting out of 2nd very easily at the III ( Stock 3rd Gear shift point) on the speedo. Strong to to 7000 rpm. The heads I did myself. Had them Fly Cut .060 to get them down to 52CC from 60CC. Opened the Intakes and D Ported them left them them somewhat rough for fuel tumble or atomization and he Exhaust glass smooth and open them up too.
Make sure when you replace Carbs and Carb Manifolds to use new Gaskets. Chased a rough running carb for about a month. I found out you can't reuse them to many times. LOL! Thought I had a bad carb and bought another and found that it did the same thing and this clued me in. So I have a 44 IDF for sale - 250.00 |
that close to the one i,m working on
the different is 94 pistons fk8 and 5.4 rods
all the otter is the same

so why did you go with the 130 cam and not 42x37 heads? I've only seen a handfull of engines with the 130 and most were 2332's with huge heads.
sounds like a fun engine though, 1.1 rockers right? |
For Vug Bug and Freddie,
1.1.1's. Just did not want to buy the heads. Runs very strong and could not imagine what it would do with the larger valves but I think possibly the 40x 35s give it good velocity. Makes it as Linear in the way it runs I think on the street.

A few years ago I built a 1679cc (with machine in 88mm cylinders) T1 engine for a friend of mine.. He put 60K miles on it, but decided to graduate up to a TIV engine for his 181 (and never look back!). He ended up donating me the tired RAT 1679 for R&D purposes a year or so ago.
I recently bought a 73 Super with no engine and had planned on throwing a TIV into it, but just haven't had the time to prepare one.. Well my Nephew has been in training with us for a year now, so I decided to have him tear down the 1679, reconfigure it and patch it up for some service in the Super. That worked well since I could stand another daily driver with heat while I finish my 912E revitalization, so I don't have to drive a damn 996 everyday!
So the 60K mile engine was torn down, the only thing that was worn were the camshaft thrust bearings. We honed the cylinders, replaced the bearings, replaced the rings and did a good valve job with new valves. The only changes I made to it was adding an Engle FK-41 Camshaft coupled to a 1.4 ratio rocker, a .035 deck and ended up at 9.6:1 CR.
My Nephew then balanced the assembly and assembled it. We topped it off with a Mallory Uni-Lite Dizzy and an ACE prepped single 40 Dellorto DRLA carburetor. I ran the single to keep the engine super simple and easy to work on. The Ace prepped carb ran perfect out of the box and needed zero tuning to dial in perfectly at both part and wide open throttle.. I only needed to touch the mixture controls.
All in all the cost to reconfigure the engine cost 237.00 to include the new cam and Engle lifters, bearings and rings. I spent more on the carb rebuild than the entire rest of the engine as it was 95% used parts, a true sweep the floor powerplant.
So today my Nephew installed the engine.. We then dumped a healthy dose of RAT Snake Oil Break In oil in the crankcase, fired it up and broke the cam in.. I then took it for a blast up the road and I was amazed! I returned from the blast up the road and rolled it straight onto our chassis dyno where it made the following power.
Now, its been a long time since an engine only made 70RWHP on my chassis dyno and we have never assembled an engine that made less than 100 RWHP on this dynojet. Its kinda of hard to get super excited about such little power, but this engine is REALLY IMPRESSIVE. To create 70 RWHP means this engine is producing 20% more power at the flywheel,(roughly 85HP) now I wish we would have taken the time to bolt it on the engine dyno too!
The torque curve is impressive and extremely flat with a huge concentration of torque below 3,000 RPM, perfect for the tall gearing the Super has as it was previously equipped with a 2270 TIV that loves tall gearing. 75MPH is achieved at only 3,400 RPM between the tall tires and tall gears, but this engine pulls the gear very well, unbelievably well.
I never expected this engine to produce this much power, or to have this level of throttle response with a stock weight flywheel and a single 40mm Dellorto with no port work and simply prepared 041 valved heads.
Even the exhaust system is used and its only a 1-3/8" Chinese system with a single quiet pack... It fits this combo perfectly and appears to have more potential in the top end as the engine is still leaning out up top, not richening up, which generally indicates inefficiency.
I highly recommend this combo for anyone wanting to build a small displacement, great driving, cheap torquer combo. The FK 41 camshaft is really impressive, we'll be watching oil samples from this engine to monitor the life of the new Engle lifters and to continue our oil development... The FK 41 was the cam that was closest to what my camshaft iterator chose for peak torque at such a low RPM when i set up the iteration parameters within the software. It is performing exactly as I expected, and that torque curve reminds me of a TIV!
Its been twenty years since I've driven a ACVW with less than 140HP, but this engine is so snappy and fun to drive, I don't miss the added power as much as I believed I would.. Its not "MassIVe and its not bad ass, but it is simple, does have great heat and didn't cost me anything to create while giving my Nephew more experience. I'll be doing my best to break it for the remainder of the winter!
I expect insane MPG due to the efficiency of this combo and the gearing.. We'll have to see!
Here is the recipe:
69X88
DPR 69mm CT/WT crank
Stock 311B rods
FK 41 cam, 112* LC
.035 deck, 9.6:1 CR static
Single Dellorto 40 with 34 vents
Genuine 041 heads, no port work, competition valve job, port fluffing only
1.4 ratio rocker
Manton pushrods |

Quick update on this engine. I bought it from Jake and it's now in my '64 Bug and running dual 36 DRLA's. The trans is stock '64- 4.37 r&p with 205/70 tires. I haven't checked the mileage yet, been too busy beating on it so far.  It doesn't lauch as well since I lowered the car, but I expect it to run low 10's at upper 60's mph in the eighth mile.
I haven't had it dyno'd to see what it makes with the duals, but here's a vid of it going through the gears.

Please post drag slips, my 1699 with stock heads did 10.6 @ 64.6.
ANY kind of traction in first would make it a lot better |

I wish I could figure out how to post pics. But I´m a pc imbessile 
This was an experimental engine that we built to try some things out. The final engine combo is slightly different due to both build price and better idle. but this one still hauls butt.
Here goes:
1914 std plus.
Stock 69 mm crank.
Flywheel lightened 1 kg.
CB Unitech rods.
26 mm oil pump. Full flow.
JPM cam 240/433" X 240/394"107 LC
Stock shortened alu push rods.
94 mm Mahle cylinders
SS pistons
043 heads ported and polished. - The full version. 35,5/32 mm valves. 10-1 CR. Sgl. HD springs.
009 distributor w. Ignitor, recurved. 3 OHM coil.
Modified 34 mm Solex PICT carb, to 38 mm w. 30 mm venturi. Modified CB center section, hand made endpieces like the F.I. ones, but with 32 mm. I.D.
1½" heater boxes
1½" CSP "Super competition exhaust.
45 hp @ 2500
60 hp @ 3000
90 hp @ 4000
97 hp @ 4450
94 hp @ 5000
90 hp @ 5500
128 Nm @ 2500
140 Nm @ 3000
162 Nm @ 4025
134 Nm @ 5000
118 Nm @ 5500
Runs almost too cool. In the summer time it has a power pulley installed to reduce cooling a tad.
It loooves long gears, and is hooked up to a 3,88 R/P w. 0,89 4rth.
Does 18,5 - 80 mph in third, in 28 seconds. (A good proof of the powerband of the engine)
Like I wrote initially, this is an experimental motor. The final version was detuned a tad to 90 hp because we could build it for about $600 less.

1 1/2 deep sump, full flowed with external oil cooler
1 5/8 ceramic merged header with magnaflow muffler
stock 68 swing axle trans (trans will be next winters project to upgrade)
Haven't raced yet, car runs rough and continuously blows black smoke (burning fuel) linked this problem to the carbs. I don't think its running to its full potential yet. once the EFI kit is installed I will put it on a dyno and also race it, then post my times and dyno info. |

Sure why the Hell not. Not an overly aggressive cam, nothing wrong with running premium. A lot of us run big dailys and 48s. No body said anything about needing to have absolute best economy. Drive it and don't let anyone talk you down about it. Drive it cause u want to.

i have a CB 76 craNK, Hbeam 5.5 rods,
AA 90.5b pistons
sp heads with 37x32 valves, ported and valve job by brothers, single hd springs, i need .50 deck height to get 8.5 CR, dont remember the CC of the heads right now.
webcam 163 on 105 lobe, thanks john@aircooled,
gene berg 26mm full flow oil pump,
kadrons from kaddieshak with 30 venturis.
the same kymco 1 3/8ths header/jtubes with custom 2inch exhaust and muffler.
mallory cdi box,
ngk d6ea plugs, maybe d8ea ( i have both sets, just not sure which to use and not sure about the hot/cold plug thing)
breather box,
2.3-3psi electric fuel pump,
Aircooled's SVDA distrubutor curved for the ICTs i had,
1.25 rockers,
aircooled's hd aluminum push rods,
windage pushrod tubes,
stock weight flywheel, i do have a l/w one too if needed,
kennedy stage 1 clutch.
taking all the rotating stufff to be sure it's balanced, i know most of it is supposed to be, i dont know where to get a scale i could use to just weight the pistons n rods myself.
scat doghouse 36hp fanshroud, getting a friend to put some extra welds on it,
hoover bit.
so whats everyones favorite break in oil, just cheap 30 weight with the lucas oil breaking additive?
also i was thinking of using 5w20 instead of the usual 10w30, what do y'all think?
i'll see what the oil pressure is on the new engine whith the dino oil. my current engien has almost 60psi at idle with 10w30.
so ...should i stick with the 8.5 CR?
i have 7.6-1 now and its running about 250-300 for temps using the same heads that i will be using on the new motor(yes when i got the heads back from brothers i couldn't wait, so i dropped the 1776 to switch heads and install the new kadrons, but my head temps went down 50-75 degrees)
and which plugs, hot or cold, d6ea or d8ea?
expected HP?
straight axle 4.12 67bus with 205/60/14 rear tires
thanks!! |

i have an extra lightweight flywheel, i've been told not to use it in a bus since the bus needs the inertia of a stock weight flywheel, but if the crank is counterweighted there would be extra weight there?
so could would there be any gains from using the lightened flywheel with counterweighted crank in a bus?
if i bump my compresion ratio to 8.5 from 7.6 will that make my heads run hotter?
what are the pros and cons?
more power, hotter heads, higher octane gas, pinging, detonation?
i'm getting close to setting all this up, need some help to make my final decision. |
