[jimGTS]

Ive got the petrol, you bring the matches,

WE GONNA HAVE A BBQ!!!

wheres my chicken and steak?

extra mustard for me!

Not until I get back on Thors dyno at the weekend !!!!

sounds good to me Dave, i'll be there.

doesnt it tik you off mate, cause my car runs like a dream, and when you here it should be more than what it is, it makes your blood boil.........
soon to me greedy spec 2'ing it soon! (altho now power gained, lol, should look sweet)
can yuo set the overboost to -20psi?? i want a red theme fella?

Not sure to be honest Jim, my overboost is set to 40psi lol because i never want to hit it as the flashing and beeping does my head in. ive got the FCD to protect me if anything goes wrong.

i'm consistently hitting 15.5psi in lower gears and about 16 in the higher gears so no problems there. Just this damn overfueling above 5000revs, dodgy AFM maybe? or just the ECU not having maps for the increased boost?

i really woulnt have thought ecu mate, there a loads of rev1/2s peeps who ecus are ok above this, more of a single sensor, part sort of thing.....
but if your getting a ecu, good on ya.......pure newbie guess tho (so dont listen to me )

i wanted to keep the red theme going really, but if overboosting on the "set" -20psi means beeping, flashing etc etc, hardly werth it! be a PITA!!
lol!

youll be fine fella! you got a kicka*s sweet looking car, still kills most things on the road, plus you got new monster turbo on the way!
woohoo!!!
not the be all and end all mate!

Cheers Jim, sounds good when you put it like that, the turbo is all ready to go on, sat in my garage along with the downpipe.

Just need to get it all running right in preperation to fit it.

As for a dodgy sensor, i thought this would throw an error code? which im not getting.

I dunno, i'm going over to thor at the weekend with Dangerous Dave so i'll pick Nod's rather huge brains (again)

dont forget mate, error codes are only werth while if the sensor is totally dead!!! even if its running at like 2% good it still wont throw up an error......old and worn parts wont throw up errors but they can still cause problems fella..this is why its a pain!!
its only until you get good AM sensors where theres a little more response and feedback..and obviosuly the new ecu will tell you all you need to know, get a call laptop pluggin module and youll be sorted (propper F&F )

Just comparing Olly's dyno chart with mine, I noticed on his, a slight 'spike' in power & torque at 5700 RPM - see below.



I have a similar spike at 3200 RPM before my torque just slopes off. What could be causing that? - see below.

[jimGTS]

have to say im impressed by all the info it tells you on the printouts, our essex RR was purely a graph and power numbers, that was it, lol.....

heres mine (you can see the dip past 4500rpm where i start losing boost......)

final peak power at 0.9bar or 13psi........

[DannyW]

My graph with the key to what the lines mean, sorry for the quality, its the best i can do.







so i actually got 217 flywheel hp, what a sh*tter

I wouldnt worry about it mate - mine is the same as yours. If you look @ import's graph @3000RPM hes only making about 75bhp where we are at 150. His boost seems to come in all at once - very much like my mates cossie - meaning he has to rev it harder to get any performace. Personally i prefer to have some low down power - esp on the motorway journies. The spike could just be the turbo running out of puff - at higher rpm the engining will consume some of the boost anyway

Don't get me wrong - I'm not necessarily worried; just curious really! Your chart shows a very similar torque curve to me (in the way it just drops off), although Danny's shows a marked change in the curves at around 2700 RPM...which I guess is the turbo coming on boost? So...perhaps it's a fuelling issue not perfectly matched to the boost at that RPM?

[the_did]

it could also be that he has a different revision - the two turbos seem to have very different characteristics (not that i can spell it!)

also look at his max RPM - over 1000RPM less than the rev 3's

hense why you here the expression that ct20bs,ie rev3s can boost to the redline, ie have there power between 6500-7500........
its the downfull of the ct26, which looses out past 5500......however, having power higher in the rev range is not all what its about....

the ct26 is more common to produce more torque than rev3s, especially when modified......
ive only a few mods, and am running the same boost as you stock rev3 guys.....but even on mine you can see i loose lots of power past 5500.....altho still hitting 260ish fly...and 264 torque....
if i didnt have such a weak actuator, and could actually hold 15-16psi to 5500 even, i would be making another 15-25whp (20bhp fly) for sure.........

DannyW, i would ty and look into whats going on, a graph can tell you pretty much what you need to know to fix your problems, and the kind rr told you whats going on which is great.......clearly your car still runs great, so its not something that has to be done asap, but i can imagine how you feel, i was and am still the same because of my old and worn actuator...

I won't be returning there thats for sure!
My car made 262bhp/336Nm (230ishlb/ft) - on a 93k engine with 17psi decat, exhaust, filter. (rev 3)
That guy didn't have a clue though! He didn't seem to be strapping the cars down hard enough, and the sitting in the boot thing was just plain ridiculous; surely thats not needed with these relatively low powered cars. Did you notice that all the sensors were on the side not being used. A complete joke. No boost pressure or lambda measurement.
It seems like thayve just got the RRoad in there and are too skint to do anything else/use it properly. You get what you pay for I guess.....

Well done Jo for getting the day to run smoothly =D>

how can you expect them fit all of this and still run 20cars.......if you wanted all of this fitted, you need to spend a good 1-2hours on a RR by yourself.....
the day was purely a POWER run!! not a diagnostics/help/every sensor hooked up.....
hell id love all of that to be honest, but on these RR days there just not time, unless of course you got with say 5cars or something...

[Sidewinder]

I must admit to wanting a bit more data about the car on the charts, but fair play about the time issue. My car hit the rollers at 3.20pm, so gawd knows how long the day would've gone on for had Gordon hooked up everything to our engines!

I'm probably going back there for another run and to have my Unichip fitted (assuming they can do it), so it will be interesting to see the results before and after.

Thanks Jim - as you pointed out - this was just a power run and not a tuning day! hence daignostics not done. they have, in my opinon, set up and tuned some very quick cars! (keep your eyes peeled at pod)
can't make everyone happy tho'
ps: if you had come to the pub (yeah i know it was late) he had very technical chats with a few people.

[kevin..in]

'course if anyone knows where you can get a full RR tune up and diagnostics done for £25.00 we'll all go there. we got what we paid for and what Jo advertised and we had a good day as well towards the end there was a real buzz with people already talking about next time, whatever your recorded output this was a very successfull event and will be the first of many. Well done Jo wherever it happens next time I'm already a deffinate =D> =D> =D>
