Uprated Camshafts

[Sam@NP]

Evening all.

I am currently researching uprated cams and have come to several conclusions.

428s = Good but £600
421s = None seems to have them.
Pipers = Some rattle some don't, make good power and are £200 cheaper
Shrink = Epic if you can find and get a second mortgage.

Now what experiences have the good people of CS had?

Are Catcam worth the £200 premium?

Are pipers a POS?

my 421's have literally just been fitted, and on standard ecu they are much more revvy. Lumpy mind Trip to TDF me thinks

Why not hold out for Matts cams? I only went for 421's because I got them at a great price, and the rocker was off anyway

 

[foRSter.]

I heard from somewhere that catcams will become available from other suppliers soon might become cheaper? But yea I'd be waiting for the tdf cams

 

[Nick r26r]

what about engine dynamics cams ??

 

[Gt rob]

are regrinds any good?

 

[jack_kemp]

Not many people go for 421's because they are a bit lumpy on standard engine management.

I'd be waiting for TDF's ones myself.

Mine's on 422's if it's any use, get Fred to take you out...

On second thoughts, maybe you should drive

I haven't heard your car yet Doug, been on holiday

TDF cams sound interesting but need some more info on them really.

Fred reckons I can get 190 bhp from 428s with my current mods, Im tempted by Piper simply because they are £200 cheaper and than will get me a new cambelt kit.

When you going for mapping? Would love to know your finding.

 

[Fred@BTM]

you are NOT having piper, not in my workshop!

TDF cams? sod that, BTM cams

 

[Sam@NP]

Pipers it isn't than.

May mate. Going to ring matt tomorrow (if they're in), and book. last time I spoke to him he said 7bhp more over 428s

 

[Fred@BTM]

421s don't make any more power than 428's, can't remember the tourque figures though

 

[Dave.]

Mine made 193 at matts on 428's, most 421'd cars are lucky to break 190

Yours was abnormal though. We'll see anyway.

 

[Fred@BTM]

^ive done 4 over 190bhp with 428s

 

[sideways danny]

not peak, but they make loads more through the rev range. Peak power tells you f**k all really

 

[Fred@BTM]

meh, 14.0 1/4miles tells me all i need to know :rasp:

that and 428s work on the stock ecu

 

[Jonny1*2]

Stock ecu is gash though, so 421s are win win

 

[Fred@BTM]

i did a car 2 weeks ago on EC1 with 421's, stock inlet, 428's were similar/same

 

[Quade]

Mine makes well over 190 bhp on 428's with the standard ecu, with 167.5 ft/lb to match! TDF mapping FTW!

 

[Jonny1*2]

Hopefully that won't be the case, but AT's will make a difference

 

[Fred@BTM]

the 428 cars on ITB's do 210 with 170tourqes for reference

 

[foRSter.]

you are NOT having piper, not in my workshop!

TDF cams? sod that, BTM cams

I'll call you in a couple of weeks

 

[Jonny1*2]

Hopefully Mr Faulks can work his magic

 

[Dave.]

i did a car 2 weeks ago on EC1 with 421's, stock inlet, 428's were similar/same

big difference in the midrange torque tho fred, me and alex compared the graphs with mine prior to the bodies, and his torque curve was definitely better, nearly 20 ft lbs 2500 rpm earlier in some places!

 

[sideways danny]

he'll never admit it. That would mean I'm right

 

[Naith]

i like dougs cams, what are they, was lumpy as hell on idle but on cam i think i actually poo'd.

obviously this didnt happen and i havent test driven your car

 

[Sam@NP]

Doug is running 422s.

428s seem to be the order of the day than. Just hope some come up in the for sale sections at a reasonable price so I can get them ASAP.

I think I've seen one set in the past 4months

 

[Fred@BTM]

i admit it, M10 bolts through a radiator are a genious idea

 

[Sam@NP]

I was looking at my Rad the other day Fred but I can't see where the M10 bolts go :S

 

[Dave.]

Let's all leave the hand bags at home eh!

 

[sideways danny]

wouldn't know never done that. however M6 (I thought you were an engineer? shoudl be able to tell the difference) with nylocs is racecar proven

 

[Poopensharten]

Can you run any of the mentioned camshafts on standard management? What figures can you expect? Sorry for the noob question

 

[Sam@NP]

Yes and figures stated in thread.

 

[Dave.]

428's, 421's, ed's all work on standard management with proper mapping

 

[Poopensharten]

And they take the same abuse?

I wish i knew more mechanically

 

[Jonny1*2]

428's, 421's, ed's all work on standard management with proper mapping

421s will, but need standalone to get them to run properly. Idle is the main issue. Mines running at 1200rpm currently just so it doesn't stall

 

[SharkyUK]

Hmm... I'm liking that torque figure. Think I might well go down this route (once the aircon has been removed).

You'll probably not find it that interesting really...

Have you actually had a drive Naith? Even I've not driven it yet!
Soon though, my precious.
