What are you trying to achieve, Tidgy?

I don't know if it's the same for Avcs cams, but on non avcs hotter cams bring the torque further up the rev range, so you loose out on bottom end power (maybe not a problem on a 2.5, mind).

Laser etched with their name and logo so technically they are lighter

On a serious note tho i'd like to know what sort of gains can be had from a basic set of drop ins as well as what sort of losses from lower end of the graph.

Afaik they just shift the torque curve to the right ?

Wonder how they affect spool too

I want to retain oem drive what ever I do, so I'm not expecting mega gains.

But I'm pondering on of spool and power can be marginally improved or if you have to sacrifice one for the other.

I don't think you'll be able to improve spool and power, sadly. It's either/or from what I've seen.

Doing a good job and selling rebranded parts as if they are unique are 2 different things.

No doubting they can do a good job when they want to, when not wrecking cars on roadtests....

I just like to take the pi55 about the whole Blouch/SC turbo thing.

I was away when Raggy got his car sorted. Did they ever get to bottom of what the fault was or just replace everything & forget about the old issues it had when they went away ?

Cant find it on any his threads. Some are a good few hundred pages too.

you maybe right smurphy but he praised them for their work, he had bad experience with a well renown mapper And he took it to scoobyclinic who sorted it....I’ve never had an issue scoobyclinic but a lot of people to bash them..there fantastic as far as I’m concerned.

so instead of messaging here did you message them? I would have not paid or sent the car back if the issues were that bad...BUT on raggys side I can’t believe that his twin scroll sc42 does nothing until 4500 rpm with all the additional goodies like headers, syvecs...etc...he would have been better with the Owens turbo

The clinic are aware of the issues with COVID and things I’ve not had a chance to take it back
bit it will be going back rest assured
I have great time for the lads dere my car was 97 percent sorted out but it should of been 100 percent
I’m not a blind fan boy I’ll say it as it is
Look at my dyno graph nothing until 4500 and gone again at 6500

anyway let’s get back on topic aftermarket cams

Yea no doubt one of most experianced with our cars in the counrty. You will never find a garage without an unhappy customer.

I just remember how that whole "test drive" saga went but tbh it looked & sounded exactly how i regularly drove my car hahah.

Given their long history i am shocked that their most prominent "Fanboy" hasn't been able to find a before & after ?

All i can guess is that most folk don't just add cams usually going for headwork & or big builds too makimg a before & after comparison a bit pointless, hopefully they can dig something out their library that goes well with this thread.

I always considered cams but losing any less from low down the rev range was never something i wanted, unless adding more rpm up top was an option via a higher redline. But cant see the 2.5 wanting to spin much beyond 7500 nvm 8 or 9k for too long and remaining happy. I'm a sucker for a high revving engine but having the fozzy now with everything it has down low has almost changed my mind as far as road cars go.

The noise of a lairy cam on idle is worth it alone if you ask me.

There are also so many diff cam profiles available that testing them all back to back would never be viable as great as it would be to read the results, i will be watching this thread with a keen eye as most the cammed cars i have seen are all silly power. Be good to see how a set can help between 4-500bhp.

500 @ 1.5 bar with cams
500 @ 2 bar without cams

I’d go with option 1 for reliability especially with a 2.5 forged or not

Your one of only a few on here who I listen to with interest as I’m a massive Subaru fan and I like to learn from the most knowledgeable 👍I love the enthusiasts like myself but love listening to the people in the know 👍

from my own experience aswell I’m sort of at the conclusion now that the ej20 is going to be laggy with anything other than a 400bhp turbo or less...my old blob with the sc46 and methanol would probably get beat to 60mph by my widetrack with the standard vf35. There was nothing before 4500 rpm with the sc46 whereas my vf35 spools at 2500rpm...made me rethink my original plans of Going for a 450bhp lag monster

Oh you flatter me, I only seem like i know a bit because all the old skool guys i read and learned from have left, the real pro's have forgotten 10x what i know & still would have me looking like a schoolboy if they weren't too busy and were able to come on forums to argue about all the silly things i love stirring up. I love my Subarus but tbh i am just a massive car nut. So not too tied to any one brand which helps me keep an open mind.

Hopefully i don't offend anyone with my pot stirring i just like to keep myself entertained.

Back to cams tho or at least something related to them

Who has the highest redline on here that's active and willing to share ?

The Dual AVCS guys must be able to keep the down low grunt a little better than the single or non-avcs cars ?

When my Neutral Switch went on the blink the car felt like it had lost a huge chunk of power down low due to AVCS not working & that was only an old single avcs UK sti engine nvm the Dual JDM motors with an 8k redline from stock ?

What about a JDM cam swap instead of aftermarket ? Keeps everything oem (ish) with benefits of a better cam ?

Couldn't agree more

I'd say the sweet spot for an EJ would be a 400bhp 2.5 with as high a redline as possible & a turbo good enough to be on song early yet flow enough for the 2.5 to inhale up high in the rpm's

my fozzy sti feels like it would dust my old 2.0 off the line & has over 100bhp less unless giving the 2.0 a high rpm clutch dump.

I found the engine revved quicker in 1st & 2nd than the turbo could spool which didnt make it much fun in the lower gears.

Never been luck enough to drive a 2.35 lump but i hear those are the best of both (but you will pay for it). I see some folk in state with 2.7's when trawling the net. But never heard any 1st hand experiances.

The problem is that's not quite as clear-cut as that...

what if it was:

"no" cams: 300 ft-lb @ 3000 RPM and 450 ft-lb @5000 RPM and 350 @ 7000 RPM
lairy cams: 150 ft-lb @ 3000 RPM and 500 ft-lb @5000 and 400 @ 7000 RPM

Unless you're on track, i think the "no" (std) cams would be nicer to drive.

I have no idea if the figures above are realistic btw, i've just made them up to illustrate a point
