Howdy ppl
Just surveying the current status on ppl owning RPW cams in their donks....
Satisfied with the product?
What stage cams do u have with which other mods, engine size etc?
Any other useful details appreciated.
Thanks in advance. :cool:

Unless you are doing the cam installation yourself it wouldnt be worth the money. You should get somewhere around 8kw at the flywheel with them without any ecu tuning.

How different is the power delivery?.

I showed the timing figures on the stage 0.5 (Ralliart), stage1, stage 2 and stage 3 to my father who's an ex speedway and V8 Ford man. He couldn't believe how tame these cams were.

He did quantify this with saying that they would deliver improvements relatively across the board but mostly at top end.

If you're serious about camming, check out some performance V8 websites and you'll what we mean.

RPW will organinse a custom grind cam I'm told.

I'll post the cam timings in a separate thread that may be stickied.

the cam may be relatively mild.. but having only a stage one cam, the car does idle failry rough.

My cams are slightly bigger than RPW stage 2's and my idle is ok. Apparently crow cams is now doing cams for TE-TW's and they make them to any specs ya want. Cost is said to be around $800 a pair.

One thing to remember is being able to phsyically fit the cams in the heads becomes an issue with very high lift cams and the lifters in the end of the rocker arms take a real hammering

do the rocker arms need to be replaced, modified to suit stage 2 cams?

No not that i know of, i got told id have clearance and realiability issues but so far none have arisen and theses cams were fitted 4 yrs ago.
I did fit a full set of new lifters and heavy duty valve springs when i fitted the cams and i havnt had any problems...... yet.

I've got stage 1 cams in my 3.5L car, extensive head work and stiffer valve springs. My power is up around 165kW ATW on PULP and idle is barely rougher than stock.

I'm with EZ Boy on his assertion that RPW cams are tame by cam standards, but they're also designed to be completely streetable, so that's what you get.

Crow can make cams for the 6G7x engines, they have blank billets, but I don't believe they've done any yet. I was going to get some myself but according to Dallas at Street Torque their main man (Ray?) was backed with other jobs and wouldn't around to it for a month or two... so instead Street Torque launched into a partnership with RPW to get David's grinder to knock out cams to Dallas' specs. These ones are so much more agressive than RPW's normal profiles there is just no comparisson. They've been ground and should be fitted by the end of the month. Idle will be rough though :badgrin:

ok what do you guys consider rough a stage 2 cam in a commodore or a stage 5 in a 454ci chev.

How Much Do The Cams Cost? And Do You Require Harder Valve Springs?

When you guys look at cams - do you consider what physicals you are changing rather then just "stage 1" or "stage 2"??

I mean, do you know the facotry lift / duration of your current cams, and then can compare it to the lift duration of the newer cams to work out if that is what you want??

I mean - for my car - I am running 224 duration with 7.2mm of lift (from memory) and I will be going to the Jun Stage 2 cam with 266 duration with 9.3mm of lift.

Or are you ppl just happy to put things into your cars you dont fully understand and accept the simple "stage 1" & "stage 2" cams??

How Much Do The Cams Cost? And Do You Require Harder Valve Springs?
$1100 inc gst for the cams, ~ $270 for adjustable cam gears, and ~ $340 for springs.

You don't need springs with Stage 1, but they're recommended for 2 or higher.

When you guys look at cams - do you consider what physicals you are changing rather then just "stage 1" or "stage 2"?? I do.. RPW make it a bit hard though by keeping their specs a secret, presumably to stop other people copying..

My new cams are going to be around 224 degrees valve duration (262 inlet, 272 exhaust) with .342" lift. 108 degrees of valve separation. :dancin: Where my current ones are more like 209 degrees duration..

And if the cams are stage 2 what power gain would you expect over standard.

You're correct Manual.
Problem is, it seems to be pretty difficult to get cam specs from some manufacturers.
Loooong ago in different world I had 1600 Kent (Escort) with BDF 2 cams and they came with proper specs to compare.
Regardless, what I'm after is just driveable street performance, not anythging too aggressive. My Escort used to run 1500 RPM idle, any lesser and it would have stalled. It needed to be driven above 3000 to keep it ok. Revved to 7500+ wowh, that noise.... Don 't want that in to The Beast! Otherwise I get sore face from my Mrs's knuckles. :cry:
It seems I need to deside between S 1 or 2 if choosing RPW cams.
That is, if I proceed with this matter....

I'm with you there, still trying to figure out the whole stage thing - if I'm buying cams from someone I want to know duration, interlobe angle, lift and base circle diameter. The only cars I've played with cams on are v8's and fiat Twin cams.
You saw one of the cars at the dyno day manual, the blue xf, thats got a 308(48/84 from memory) degree cam with 600 thou lift(15mm) which when we built the engine originally was great as we had a single plane manifold and a 750 carby on it, scince it was built we've retarded the static cam timing put a dual plane manifold on and dropped the carby to a 600(to make it a bit more streetable as it's his only car now) so the cam is a bit over the top. I've got no idea what sort of "stage" this cam would be, but from some of the figures of stage 2 cams I've seen this would be 5 or more *shrugs* who knows.
Anyone here know what "stage" the common as rat **** 286 degree injected 304 cam is ? Nearly all the commos I see at the drags have a 286 cam in them, must suit the engine nicely.

so how much power would the different stages of cams increase. just a rough estimate.PLZ

At a rough guess. 10-20kW ATW depending on other mods.

Clicky:http://www.aussiemagna.com/forums/showthread.php?p=369629#post369629 for cam specs from Tighe Cams / RPW. I don't know the lift on those cams yet.

Ivan Tighe is THE man for cams. I read a magazine called "streetfighters" out of the UK all about modified motorbikes and guys in England and germany buy cams from him.
