Performance cam question

[MackyM]

Cheers Jim. I think my zorst is OK, a Scorpion stainless, so I can tick that item.

get a decent exhaust and 4 branch and take it to ray , let him play with the fuelling

are you talking about Ray from T&M's?

[MackyM]

That's the man 

[jims13]

yes thats him, as far as im concerened he's a god!!!  , i remember when i had my 8v scirroco gtx, took it to him to get it all set up, had performance cam, stainless zorst and tubular manifold, audi 5 cyl warm up reg , airbox and heat sheild and a healthy 154 @flywheel , not bad from a standard 112bhp.

 he always sets his stuff up properly, and if you have a problem somewhere, he'll find it and tell you how to fix it , or fix it for you if he can.

like i said, he is very good.

and the rr doesnt give you over excited figures, as ive also been elsewhere and got within 2 bhp.

Yeah you can't chip a K-Jet engine (well you can, there was a K-star chip available, but these are hard to find now).  I just meant the 2.0 ABF can reach 170 without any serious engine work, so it should be no problem to do the same with a k-jet 2.0.

I guess I stick to the bigger lump and get it properly set up on a RR. With an exhaust and filter I reckon it might hit 170 brake? Does that seem unrealistic?

went to stealth racing with my 2.0L 16v (standard 9a cams, 4-2-1 TSR manifold, full ss exhaust) last week and it got 164.9 bhp (at fly) (120.1bhp at wheels) and 147.1 lbs/ft torque. with KR cams Vince (the guy at stealth) suggested that it would reach around 170-175 bhp.

he said with a 2.0l 16v, p&p head, cam, exhaust, 4-2-1 fannymould you should be expecting a reliable 200bhp at fly. although there will be fluctuation between different rolling roads, conditions etc, of as much as 10%

[jims13]

so the question is , does anyone have  a source of 9a lumps???  people that no what you want them for want a fortune.

Back to the origional question about cams. Its not necesarily true that you have to sacrifice torque when upgrading your cam. With cams its not all about the degree of the cam! You also have to take into consideration the lift. You often find that cheaper cams even well known brands are re grinds which because they have had material taken off give less lift even though they are now a higher degree of cam. So when looking for cams do your homework and shop around getting details of each product. As always you get what you pay for. Ive just bought a set of fast road schricks. They aint cheap but are the dogs dangilies when it comes to cams. They are a 268 degree cam with a beauty 11.5 lift. The grand total was about £450. Anything with a lift below 10 is worthless and you would be better off with standard cams.

So with my new cams, a ported and gas flowed head from SP Performance, 4 branch stainles manifold and zorst a lightened and ballanced 2 litre bottom end im hoping for around the 200bhp mark. Keep your eyes peeled and i will be back with the evidence when its all done and tuned.

Very impressive  Where did you find your 2.0 lump mate?

[Judderi]

I found it on the bottom of my engine   

I bought the car already converted. Altho i am in the process of taking it out. From what i can see its an audi lump marked as 11J and a big old 2.0 stamp
