There are advantages in reving your engine past the power peak.
It just depends on how fast the power drops off.
In some cases you have to go way past the peak
so that in the next gear the power is still significant.
This is where dyno graphs are very useful.
Even if there is 20 hp less at 7000 for example,
there is still an advantage because when the engine drops
to 5000 in the next gear it may actually be less than this.
This is the reason for closer ratio gears.
Even if you don't believe in a dyno's HP acuracy, knowing
the RPM where peak HP and TORQUE are, can be a great advantage.
Hope this is relevant to the thread.

Shiftys engine at 100 Hp should run in the low 14's.
Being that he is building it for Nitrous and for the
street, comprimises to N/A HP have to be made.
With a 100shot, 11's should be achieveable.

thats what i had in mind dave, Ill quite happily compromise my NA power for a larger total figure on gas. I will be trying a very large cam combo due to fact that i want to rev this high when on nitrous, same or higher hp but lower peak cylinder pressures is the idea. Wearing the motor out quickly is not a concern, its not expensive or hard to freshen them up. My llmiting factor at the moment will be the VW id springs. Ill have to check the seat pressure and lift on them.

Revs


I rev my engine at least 1000 rpm past it's peak power because it's proven faster than changing to a higher gear. I've held 2nd down a short straight in in the Grafton hillclimb and third down the back straight at Wakefield park and compared the times to changing up and it's just not worth the time loss.

The other point is high revs are feel more aggressive and more fun when you're trying to go your hardest. The engine also sounds good at high revs which is cool for the drive and the spectators.

I suggest listening to Greg Wards hillclimb car at wide open throttle at max revs. It sounds like no other volkswagen.

If you want longevity and not revs then stick to a stocker and go and read anther post.

My New engine should go in next week, so hopefully get some dyno figures etc in a few months once run in and properly tuned. But basic specs

- New mag case (stay within PRC if ever i want to go down that road)
- cb 69mm crank- offset ground 72mm stroke
- 94mm barrels and pistons (with crank gives 1999cc's)
- 10.6:1 CR
- Engle 120 cam
- 1.25:1 rockers
- CB wedge ports
- 48 ida's
- Will run a simple 009 for now (msd or mallory will be in, when my bank accoutn recovers)
- plus all the other little bits and pieces all new except for second hand german tinware.

It should be resonably quick for a sub 2L motor, but i think the bike may still have the edge :D

Also it will run with a std L bug SSP gb, but with a 1.44 3rd.......

Hi all, i have bought this type 1 2275cc engine from delux66(damo), it was originally built by Stan Pobjoy over 10 years ago, he just simply rebuilt with new crank and cam bearings, new piston rings and new gasket kit. The engine has a SPG Roller crank in it. I have a list of all measurements obtained in the build: 2275cc Roller Engine Assembly tolerances:

Camshaft Axial Play : 0.06mm
Camshaft gear to crank gear backlash: 0.02mm
Cylinder Shims: 1.15mm
Crankshaft endplay: 0.09mm
Deck height TDC: #1 1.78mm #2 1.81mm #3 1.78mm #4 1.76mm
Head CC: #1 67cc #2 67cc #3 67cc #4 67cc
Calculated Compression Ratio: 8.1:1
Total valve lift : 0.460” or 11.68mm
Valve geometry set @ Half total lift: 5.84mm
Stroke: 82mm
Bore: 94mm
Rocker ratio: 1.25:1
Crank mains: 0.25mm under ID, OD standard
see pics of the build here

all i know is its the best vw donk i've ever owned runs awsome pulls hard sounds awsome (through the cannons)my neighbours prob dont think so

Get rid of the cannons! Fit some conventional pipes and it will run even better... and be quieter

personally... i love the noise could be louder
but can you tell me
1. why it would run better
2. by better do you mean more power or more reliable
3. would a 4into1 header with stinger be the go?? what size pipes 1 5/8's???

well-tuned harley? is there such a thing?!

If they are anything like the cannons I know of, the pipe lenghts etc are woeful and what you said about exhaust speeds is on the right track

Ok,so im only waiting on a starter alternator and a muffler,the build starts mid June.Cam is now a V-26 like a W-120 for ratio rockers.All rotating assembly has been ballanced to a nats ball by Crankshaft Engineering with paperwork for before and after ballance.
Also acquired
LM-1 wideband with rpm converter
Berg oil filter kit and vented VCs
Stage 1 clutch
Daiken super disc
Lite flywheel german
CSP headstuds
CE straight cuts
BMD pulley system (for the #ank factor)
and really too much stuff to list,#hit loads of the little stuff and vw tools,everything new except the carbs.Just have to do a preassembly before my hols so i can order the manton pushrods.I also changed my CR from 9.5:1 to 9:1 by machining the piston crown,why because i wanted to keep my chosen deck height of 0.045,and because i can :P
