awesome Pete!
Ill come and have a look before xmas and drop off that coolant hose while im at it!

[Peter Jones]

Hahahaha!

The verdict is in - a massive 68kW at the front wheels!

Numbers don't neccessarily tell the story though - it goes like stink!

Very happy with the work.

It will now break the clutch loose if you nail it in third @4000 and it's a brand new 16v 210mm disc and pressure plate. Might have to upgrade.

Work performed.

Secure vehicle on chassis dyno as required. Dyno Tune, scope and gas analysis (under load). Connect fuel system fuel pressure gauge duuring dyno testing. Run vehicle/engine at various speeds and throttle loads. Recalibrate carburettor progression, cruise, power and main circuit fuel mixtures. Adjust camshaft position 2° advanced and 2° retarded = 0° is best position. (edit - Guess I can use that adjustable pulley on something else now!) Plot and regraph distributor advance curve to suit engine operating specifics. Power time distributor. Carry out power graph as required. Check and readjust idle mixture.

Main jets are now back at 145.

A couple of quick test runs and the 5000rpm ceiling has gone, it keeps on pulling well up to 7000 now. More driving required to re-learn how to drive it best.

Here's the plot, click thumbnail for the high res version.





I'll be interested in the keyboard analysis.

I'll be upfront and admit it makes less than either an APR or GIAC chipped MK5 to get that argument right off the table straight away .

It's a blast to drive.

How much torque Pete? Thats what pulls u out of the corners

[Preen59]

Nice Pete, I bet she goes rather well now! From the graph it looks to be running out of legs a little, but that's ok.. Its got huge midrange! Glad to see it all got sorted.

Massive torque doesn't equate to massive acceleration..

Pete! just read your project from start to finish in one sitting!!!
Great work. Please continue enjoying the ride.

[GoLfMan]

great to hear Pete

[Geoffrey Hale]

Pete...Good stuff.....get some fun happening now after all the hard work you've put in. Look foward to checking it out some time.......Geoff

[Jarred]

Nice Pete.

68kwatw, so 90-100 kw at flywheel? so 125 ish HP?

Glad to hear it's gotten all sorted.

That curve shows a massive mid range, this engine might be better suited to hill climbs now even?

Was the car strapped down properly?
Did you have the correct tyre pressure??
Was your Intake temp sensor tampered with???

I call BS on the base that I think that your turbo has too much flow for its size

Nice work Pete great to hear your car is getting sorted, still laugh when I see the pics of the air horns

ahhh Touche!!!! all 12 witnesses were lying too?

nice results Pete, definately wanna have a ride in the beast, I couldnt think of anything better than the sound of twins at full blat at 7000rpm

[WABIT]

are you sure it right pete, i made 66kw about 2years ago with my gti spec 1.8 8v?? and that was running ritch and had the standard cabrio exhaust
edit: and i also think tim made 66kw over 12 years ago with his beater

Honestly - don't know or really care for that matter the goal of the exercise was to get it running right. I'm confident now that it's running as well as it possibly can.

I'll have to check back with them on the torque figures, I'm pretty sure this thing's got a lot more torque than a 1.8. The clutch is a brand new Sachs HD 210mm disc and a brand new 16v pressure plate and the car will spin the clutch easily from low rpm in third with the clutch already fully engaged.

Remember this is a stock $50 2.0L bottom end with a stock 1800 K-Jet head. Cam and carbs can only do so much

The real measure will be (hopefully) improved lap times out on the track.

hey mate - great to hear you've got it back and going strong! i suspect that with the 2l's long stroke it must pull strongly at low revs - to have max power at just over 5000 is great - means you dont spend all your time waiting for power to come on and makes your gear changes less important - always a good thing for the practical driver.

must sound the biz too - good job!

[Peter Jones]

New clutch is on the way.

Next event is Phillip Island Famiarisation / Sprints on the 14/15 of Feb so I've got to get the clutch installed before then.

I think I'll just do the Familiarisation on the Saturday, still need more track hours before I commit to a season of Sprints.

Went for the over kill option on the clutch. Went for the soft option on the spring/pad options though, it still gets used on the street after all so I went for the 6pad & sprung centre disc. New hardware on the way from GAP to bolt it all up. This'll test those urethane gearbox mounts out!

I just read this thread from start to finish, what a morale booster! I was planning on building another MK1 with 1.9 turbo motor but from the sounds of things your hybrid on carbs would be more fun and sound sweeter.

Thanks for posting and all the photos.
