ABF Tuning

[Dave_R]

Got some money saved, still not enough but wanna do some research. I'm going for a Gas Flowed Head, 268 Shrick Cams and a Re-Map.

At the moment I have a panel filter & drilled air box and a 200 cpsi Sports Cat, I'm just wondering if using a Sport Cat would be okay with cams or will it be better if I go for a de-cat? I have heard a few times that using cams with a cat can damage the cat itself.

Doesn't anyone recommend me keeping the sports cat or going for a de cat? and places where I could have the head done?

Cheers once again, Dave

Cams plus cat does not equal damage, given that you have cams in there already and that the fueling will be mapped ok.

 

[Stu_HR]

IIRC the 16v CAT & xorst are pretty good at extracting the gases as its a 2" system from front to back. Problem with a decat is you'll have to fit the Cat back come MOT time & then you may experience problems with the emissions test with the change in back-pressure depending on the remap. It may be worth spending your pennies on something else like a lightened flywheel or a throttle body conversion.

iirc the cat is welded on on the 2ltr16v,unlike the 1.816v which is bolted on.

Throttle body conversion? do you mean full throttle bodies?

 

[WeeJase]

i think he does.
4x direct to head ,much moola but great performance and a soundtrack that dolby should use at the beginning of the main feature of any film."now ****ing listen"

 

[H8SV8S]

Throttle bodies don't offer great performance... they better the performance of an engine that already went well.

That is to say, there's no point putting them on a stock engine; you need a hell of a lot of work to make them worthwhile

The best possible mod you can make is to lighten the flywheel and add a 3.94 ring and pinion. Or, alternatively, run a 195/40/16 tyre to drop the gear ratio down a touch.

Headwork is next on the list.

This is sort-of part true. If you go for really lairy cams with lots of overlap, then you'll be spitting quite a lot of unburnt fuel down the exhaust at idle. That won't do the cat any favours. 268's as you suggest shouldn't be a problem though.

A pair of schrick 268's will probably not be Cat and MOT complient on a std ABF management system, I seem to recall from posts long ago (esses3 ?) that one of the cams was left stock and the other changed for a 268 spec and it went really well - seem also to remember that sean martin tried a pair of 268's and couldn't get it to run right at all on remapped std management - ended up with a pair of 260's.......personally for a car that you need to stay emissions friendly I would go for a nice head and a pair of 260's - also as HSV8S has said above, the gearing in the stock abf box is total shite - get a 3.94 from a passat and a quaife diff while your at it, and a new pair of gearbox cables and the car will be transformed - I would not go down on the tire profile if I was you given the shite state of our UK roads - better to change the final drive and stick some 7x15's on it with 205/50/15

cheers

ps - if you end up getting cams then you need to set the cam timing up properly - for thgis you need a vernier timing wheel - and I have a spare peg drive one that is absolutely the best available and cannot slip like conventional ones, made by quaife actually but not available in the UK (got mine from the USA) - PM me if interested

Hi
Have you thought about Nos?
When it comes to N/A cars it does cost quite a bit.
But Nos will give you larger amounts of BHP gains.
We do NOS and we use the only company that is road legal in this country.
The system is progressive too

found post on CGTI - ess three -

stock exhaust and 268 in, nice head, well put together, stonking result

 

[Stu_HR]

Ooooh!

 

[Dave_R]

Think I better have more of a look into this now, rung up Stealth Racing today and they said that only Shrick Cams get the best out of the engine and said go for 268.

Still got a little bit more to save up, cheers for the advice guys!

 

[RobT]

total coblers I'm afraid - my car has one of the best VW 16Vers out there and it runs on Cat cams (from belgium, available in UK through badger-5), Davey Johnstone has Kents in his rally golf, again a good powerplant, etc etc, Schrick is not the only way to go - they are good dont get me wrong but they are also damned expensive - 268's will not work in your engine and stay mot friendly

 

[Dave_R]

These are the e-mail’s I had from TSR and QEP asking about prices.

After all the advice you lot given me think that the 260 cams would be a safer option, but let me know what you think of these.

Hi Dave,

a 'Pack A' Head is £647.00 including VAT on exchange.

A lightened/ balanced flywheel is £48 inc. VAT again on exchange.

Schrick Cams are £699 inc. VAT. They are a 276/ 268 profile. The TSR equivalent are £420 inc. VAT for exactly the same thing.

We will fit the cams to the head if you order both at the same time, for free, you would need to buy a set of tappets though. Tappets for a set of 16 are £131.60 inc VAT.

Again, if ordered together postage for the whole consignment would be £10.99 plus VAT, totalling £12.91.

Please do not hesitate to contact me should you require any further information.

Kind regards

Hi,

We can do a gasflowed head on std valves for £500 + Vat.

Camshafts are £311.59 + Vat for a pair.
The cams we do are short duration/high lift profiles which give a wider powerband.
For USe with a std ecu I'd Recomend Part no's 7661207 (261deg with 11.2mm Lift) or 7661206 (261deg with 11.6mm lift).

Regards

Matthew Saville

Thanks, Dave

Ahhh, just stick a big turbo on it baw haw haw haw haw,

 

[ScottyP]

I wonder how much tsr charge to fit that lightened flywheel?

be careful not to go too extreme on the cams, I think I had 270's in my old 16v cordy and it was a right pain to drive in traffic or at low speeds - idled between 800 and 1500 rpm, sick making!
but! on the upside flew over 6000rpm, not much below unfortunately.

 

[alimac81]

If you use the car everyday better to go with the cams which give you more torque and power around the mid range, if you use it for track days alot, go mental and fit crazy cams, id go with fast road.

 

[H8SV8S]

I wouldn't fit cams at all unless you have the transmission to suit. It's all well and good to have power, but it's the drivetrain that puts it to the ground and must be matched to suit.

Again, the best mods you can make to a 16v are the 3.94 and lightened flywheel.

Once you've done this, consider getting the head ported and, after that, now that you have tightly packed (within reason) gears, you can look at getting some REAL cams.

whats a 'fast road' cam then ?
