[rich1068]

OK. Let me know if this works. And special thanks to Des for bringing me down. Today of all days

Nice one!

They look really good!

[rich1068]

Are you saying that because you can actually see them?

Are you tempted Jason? You're from CupraNet so you must have read plenty re Revo/Jabba/etc

BTW How was Tatton Park?

so tempted i was revo'd tonight,torrential rain on the way home hampered settling in,but from my initial thoughts,omfg springs to mind,just as i was getting used to the power of the 20vt ,coming from a N/A 16v,it has transformed the car,got home,changed it back to stock(10 seconds at the most)hid the controller,as SWMBO is not gonna be impressed i just paid the family allowance and next weeks grocery bill on it,i however am very very impressed,smoother than a silk thingy.
more impressed rantings to follow

Nice one Jason

3 or 4 bar?

What do you think of the 'curves'?

[ColinD]

Looking good there Rich, nice steady, good areas

Don't be to upset by Des's and others comments, there are to many variables at work to be sure without control cases, eg rollers ain't that scientific but a very handy guide when done fairly with other cars. Your *** tells you it's quick because it is...

Jason,

ohboy...not alone in that...best trick is to get two invoices done, then you can show one without hiding anything right

I feel like poping mine over to JBS later this month for a comparable test case as I don't expect anymore than 207/215 (/optimax)

3 bar mate,though at some point i will no doubt get the 4 bar fpr,think they will upgrade the software for gratis
not really been able to get a good evaluation ,as i was down in daventry(unfamiliar roads) in the dark.
the mrs is now out in our"stock" vrs,but rest assured i will be heading for my usual test track soon.
one thing though ,revo kev pulled up an intermittent dv fault so i must get this off and check it.its a forge but we weren't sure last night whether its a diaphram or piston type.
so far though ,bl00dy good bit of kit,new tyres please!!

Whats the real world difference between 3bar and 4bar?

I only ask ask last time I met James there was umming and arhing on the 4bar for the Octy, unless I wasn't paying attention. I get the feeling 4bar is a prereq for bigger blowers, not sure of it's benefits on the present configuration.

Genuine question as I don't know.

[DaveH]

Look nice them Rich, are you pleased?

[SilveRS]

I didn't realise cars were so inefficient. 50hp loss is quite a lot of power to loose through the transmission given it is fwd.

By the way, nice graphs. So a tweaked RS is putting out a real 180hp.

Approximately 1bar! . Seriously though, Rich should be able to give you some info, he had 3bar for a week and is getting on for a week with 4bar. Apparently 4 bar is much more sensitive on the throttle, a small press and its off! Also, I believe 4 bar uses a fair bit more fuel than 3bar.

about 33%?

Colin,

I'm not upset at all. Des never upsets me, he's a little angel! Actually I was very interested to hear what he had to say. You're right, rollers aren't very scientific when it comes to calculating numbers, far too many variables and allowances made (software recalculating this, software recalculating that). But you can compare. My butt dyno tells me that Revo has been an excellent choice so I'm happy with that. I also know (butt dyno again) that 4 bar feels better than 3. I'm sorry I can't be any more technical than that, I'm not an engineer, I just drive it. Actually I do more than that, I spend a very large chunk of my day sitting in my motor and I know how it drives inside out. Butt dyno again I'm afraid

Dave,

As you can probably guess I'm chuffed to bits. The curves are good and the numbers make me smile though as I keep saying I take these with a pinch of salt. 4 bar surprised me really, it is more sensitive on the throttle but not as much as I thought it would be. I had a nasty feeling it might be like flicking a switch, on/off. It's not, certainly a little more twitchy but not so that eg town driving, is a chore. With regard to fuel consumption, I really haven't noticed that much of a difference. But then most of the time I drive like somebody's granny

HI

ok hope i can shead some light on this 3-4 bar issue,here we go the main reason the 4 bar regualtor is used, is that the ko3/s injectors will only flow a limited amount of fuel,there for only a certain amound of ing advance and boost can be used(safely)ie to match the max fuel flow.By using the 4 bar the actual fuel pressure is incresed,thus delivering just that little bit more fuel.This in turn means more boost and timing can be used,and as a result you get more power.its as simple as that!!!!!

hope this helps

Is it notably quicker than the 3bar though, that's what we all want to know?! I filled the tank with Optimax today and used the Optimax program for the first time. Now I'm wondering whether I should have gone for the SPS3 instead of the 2 for tinkering with the map. Back-dated pay rise this month, can you see where I'm headed with this?

ok hows this sound

come see 1 of the JBS staff and we will upgrade you to 4 bar(foc)
go away and drive your car,come see us a week later,if you like we will charge you for the regulator.And if not we will flash you back to 3 bar,all i ask is you write a post detailing your findings.????

You can't say fairer than that Dave

Optimax. I would imagine you'd need a few tanks to get the benefit.

Notably quicker? <deep inhalation of breath, pondering reply> It feels better. Really I should have kept the 3 bar longer to give a definitive reply, I thoroughly enjoyed it from day one but what kept coming back was that I could have got something better for a little more. In no way disappointed but..., if you know what I mean. I'm totally satisfied with how my car performs now (sorry James, no more helicopter lessons for you), the Revo 4 bar along with the various bits and bobs makes it drive just how I want it to. Nice and easy in traffic and extremely quick off the mark when the road opens up in front of you.

Go for it Dave

does that oinclude other members on 3 bar program?just checking ludlow to chesterfield

[EddyH]

Jason by the time you go back the second time you'd have spent the cost of the 4bar fpr in fuel. Unfortunately I can't give a comparison as I went straight for the 4bar program. However for the mimimal cost I'd say go for it. It'll give similar gains to the likes of an exhaust and give the potential for more power from future upgrades. In my opinion it seems rude not to for the price of the 4 bar fpr and the free reflash to 4bar software.
