16 valve engines - OEM, tuned + race outputs

I've compiled all this lovely data on the fantastic 16v Golf engine. Production engines, respected tuner engine packages, all the way through to race.



Hopefully it'll get the juices flowing. There's a few gaps, as there's only so much data I can find in one hit, so let me know the missing bits please.

The race stuff never fails the test of wistful pondering, so there's loads of it!

8AS brigade: nothing to see, move along lol

Nice info

 

Here's some old Oettinger info from Scotts of Sloane Sq.

Oettinger GTI 16V 2000E
1996cc
182@6500
0-60 6.7
144 mhp
36.9 mpg (fuel consumtion at 56mph, 4-star or super green lead-free) lol
May 1990 list price 19,833.07

 

Cool, let's definitely add those. Will have a look through some books for more on those.

 

Chris some of the blanks filled in...



I need to triple check some of the added details.
All the CIS-E and KE-Motronic vehicles had cats and the potential to be run on US 91ron fuels.

 

Thanks Eddie, I've updated everything in post 1.

I've kept the ADL question over what was in the Mk1 Toledo as that car is the earliest of the lot?

Comments for the RH column would be great, to explain torque peak points. There's only one in there any that's rubjonny's from a Google search!

 

How did they raise the comp on the plus pack? I thought it was just top end tweeks, p&p wur timming etc.

From here.

And on that page it states the 1900 and 2000 have

which would suggest higher comp?

 

I think you're right Tom. The brochure has 10.5 in it, with the rest at 10.0. They clearly have the head off it, but there is no evidence of a skim. Gasflowed manifolds, gasflowed head, narrowed valve seats, polished valves + modified timing.

I think we change it?

 

Stay with the brochure for now, maybe a question mark next to it.

 

I dont understand how the golf was making 20ftlb more than the ibiza in 1996 from a very similar engine with similar power outputs - one of them seems unlikely

 

I agree - the race engines table is a pieced together list from engine builder information, 'official' declarations, on-event media snippets, all the way through to third hand information on t'internet (+ scrutiny of where it came from).

So it should be read cautiously in the detail, and caveated with those limitations, but this still doesn't detract from quite an interesting list of data. It may bring out some interesting trends but it must be viewed, as with any with any disclosure of race engine information, past, present or future, as being what people are prepared to publicise, which may of course guard the information they don't want people to know.

Then add in the non-technical wordsmithing numpties in works team PR departments, and the information is in danger of becoming very sanitised by the time it's released.

It's further complicated during phases of diffferent engines being experimented with in different cars.

eg 1 UK Ibizas in 1999 had 2 - 3 engines on the go at once, but the top of the tree was the 285bhp motor (the one they were R&D-ing), so it gets the mention.

eg 2 I'm reliably informed the Audi BTCC/STW engines had 9 phases, but I just haven't got all the data, so it's summarised to 3 rows with the main increments.

 

Or maybe a sneaky bit of marketing... the standard alloy pistons have valve clearance cut outs too maybe they skimmed the head 0.5 mm and took the piston cuts a little bit deeper?

 

Clearly whatever difference there were relates to inlets, rod lengths & block height discussed here

FWIW, I've got an Evo 2 output in privateers hands, showing 262 bhp and 164 lb/ft. It's definitely a kitcar motor, I've pictures of the engine out of the car. Builder/rebuilder not stated. That's 2005, but could be tallied with 1997 outputs.

The Golf data simply came off the face of a 10/1996 kitcar manual, which stated 260PS (254bhp)/245NM. No other sources.

Two years later, 10/1998, the kitcar manual still said 260PS/245NM, but by 1997 the UK VWM media PR was quoting 280+bhp, suggesting that VW weren't too concerned about keeping that kitcar manual figure up to date. Was it right in the first place? We have to assume it had a basis. Note also how max revs were 8,800 (10/96) and 8,000 by 10/98. It's tricky to follow that information unless one is a misprint.

This is why I've dropped the 1997-98 torque figure (even though the 10/98 manual says 245NM) and put a question mark as it cannot be the same after 2 years of competition and a 26+bhp hike. Judging from the way the Ibiza became less tractable as they got the last drops of power out of it in 1999, it's difficult to know where the Golf was by 1998.

 

AAL engine was/is 1984cc; not 1781cc. OK, I'm going on memory here now.... Power 110kW (150 bhp approx), 175N.m (130ft-lbs approx) 10.5 CR, KR cams, K-jet, "short" block. I hope to collect a sub assy within the next few days. Might post a pic or two then..

 

very good work chris

 

Thanks Craig.

Great, cheers for that - updating now. When was this engine made and in what cars?

 

Chris, I can't remember the exact years; however, it was Golf and Jetta 2 over here. The Golf and Jetta 3 never had the 16V our side; either 2.0 8v or 2.8 12v.
