Good venue, lots of people there.........

 

.......I did what usually seem to do........go, look round, speak to a few people then leave (I wasn't going on the RR).........

 

Rich, hope you get that fuel leak sorted.....

 

Smithy, hope everything gets sorted.....

 

Pete, sorry mate I forgot the ALC and also didn't mean to step on your toes (grounding!!) :(

 

I saw a quite few faces from Billing that I remembered but I didn't say hello, I was too cold to stay too long (I need to buy a new thick winter jacket!! LOL)

 

Rich, I'm now officially addicted to 'Need For Speed - Underground' so much so I'm not going the match now...... :p It's too cold anyway.......

 

Well THOR looked a good venue and they knew their stuff, I will never have my Z dyno'd, I was nervous watching it being used on other peoples Z's nevermind my own!! :cry: (that's just me!)

 

I did take my camera but never took an pictures, until I was on the way home.......I should have took more......I did want to take one of the Red Audi TT I cruised past at 140mph and he proper went for it to, I didn't...... :cool:

 

Matty.

Biggest problem I had was a bit of Det at 3000-3200rpm with my first Map/boost set up. Looking at the curves though, it probably would have been OK if he drove through it (glad he didn't though) as the good run I had peaked at higher boost then the first one.

Going to expand the maps out to max load properly now I've got a handle on where to aim for .

Worked really well up to 5500 rpm then just ran out of injector capacity and leaned out.

Shame really as the first map I had tried was producing 40ft/ib more at 2-3k rpm. Guess I'll make a hybrid of the two as a starting point.

Did you get graphs with Air/Fuel ratios too?

All the figures were at the wheels, they didnt give any at the flywheel

Hubs actaully, not the same as hubs will be mariginally higher than a wheel figure due to tyre deformation losses etc.

Then i stand corrected :) but you know what i meant

 

If you havnt been i would recommend them

 

Kirbz

Yeah i'd like to go up there at some point when my car is finished, Richie had his S13 done there, he got 511 @ hubs.

Maybe SXOC will organise a trip up there. We have our own RR guy on SXOC though (Gary from SCA in Norwich) so the club RR events generally happen there. They have a very good setup and Gary knows 200sxes very well, infact inside out.

 

I think the dynopack is deffo the best way to RR a car as you get non of that tyre slip etc that fooks up loads of RR runs on a conventional RR.

Tim some people don't even check their oil level :confused: :confused: :confused:

 

 

whats this "oil" stuff youre talking about??? never heard of it, is it some kind of urban myth?

Well after finaly getting out the bath i am now thawed out :( was that friggin cold out there or what,!)nice to meet everyone,old and new faces alike,must be an age thing but i had a kip in the office when you all went off for food/pub etc,think it was the stress not knowing if this new engine would last! :D I made 294bhp@10.46psi,with a very slight dettonation detected so run was shut off,(big thanks to the operator for knowing his stuff :bow: )this was after a run with Boost originaly set at 14psi,bad detting,lean as hell :confused:again big thanks, glad i have not been running around with boost controller switched on since getting this engine fitted,controller been playing up since i got it back,after talking with operator i have booked it in for next month to get things sorted and fitted ,theres a lot more bhp in there ;) ,must say i was very pleased with the results,i now know more than just what bhp i am getting,i have allso got the confidence back in the engine,being the fourth one in this Z,the RR session has highlighted problems that could of resulted in more trouble,in a ideal world it would be best to do a RR when any power mod is done,but then who does that!.

So whens the next RR and where,maybe G-Force, anyone ;)

Yeah a fair few of us had to top up our oil, but no-one came close to the amount I put in :eek:

Not sure how much oil I put in Timmy, I filled it just before it overflowed :rofl: ;), yeah I should have checked the oil guys, and I was very lucky the engine didn't lock up. Really not sure where the oil went as it was last changed when SE worked on the engine. Wasn't getting any smoke or any oil leaks, so I'm a little puzzled, I'll have to keep an eye on it.

 

Anyway, it seems as though the engine was very strong as I made 355.6 HP at the hub with no detonation.

 

They had a good set up there. They were also very good with their advice and help.

 

Started on 14.5 psi with the guys monitoring my Fuel and air via their wide band O2 sensor I crept up to 16.6 psi still with no detonation and perfect fuel and air ratio's. I thought 16.6 was a bit far but the guys said it was running fine. Still only going to run 14.5 psi on the roads though, just incase of bad fuel etc.

 

I was very happy with the result to say the least.

 

Thanks to Steve, ChrissyP and Mike for helping me with my ICE set up (and also Mike G's mate for the advice).

Hi stu,

 

What did you make at 14.5 psi?

Hi stu,

 

What did you make at 14.5 psi?

 

342 HP which to me tells me that although the fuel and air may have been ok, the stock tub's hit a flat spot somewhere after 14.5. Looking at the graph they seemed to run out of puff.

that's pretty good for stock tubs, id say that would be pretty much their limit; the S13 has a t25 very similar to to the zed turbo and 230fly/180wheels is really about the limit for one T25 on the S13.

this is all good stuff. Now lets see the pictures, videos and graphs!! Anyone doing a spreadie like the SE one?

just a quick question... how did they detect that so many were detting? could you hear it or did they have a knock sensor? if everyone was detting so much and didnt know beforehand i think this shows just how useless the stock det sensor must be.

You could hear it very clearly on most. Some in particular made you cringe.

 

a few say that the RR is puttin gon more resistance then the actul road in 4th.

Others say that they have always run that psi on the roads without any det.

And I think some just decided to wack the boost up. (I actually turned mine down for the first run).

Did they give you any indication why you were detting at such low boost? maybee another problem somewhere? With the list of goodies you have fitted you should be able to run much more boost than that.

Well i thought it strange as i have not detected any det for some time,deffo heard it at 14psi but no way did i hear it at 10psi,but as he said it was there slightly,maybe its the fuel regulator,maybe the JWT ecu map,but at least i know about the problem,once the fuel is there it should fookin fly, :)

Tony

is there any kind of coincidence between the chips used and who was detting?

I don't think there was scoops. :(

how good were the fans? were they pointing properly at both intercoolers and the Rad?

 

It's almost impossible on a RR to replicate the amount of airflow you'd get on the open road so making charge temp higher and detting on a RR far more likely.

i see what you are saying.. but.. on the othert side, if the charge temp is hotter, that actually means there is less air in there, therfore the resulting mix will be richer and thus less likely to det.

 

correct me if you thing im talking *****cks.

I'll let someone else do it. :)

 

Mix will not be richer, it'll be the same; the ECU only fuels for the amount (mass) of air it measures being sucked through the AFM.

 

Hot charge temps are bad, that's primarily why you have intercoolers. Oh and to get more mass of air (and hence fuel) for the amount of boost you are running 'cos the air is denser, which means more power for the same boost. :)

342 HP which to me tells me that although the fuel and air may have been ok, the stock tub's hit a flat spot somewhere after 14.5. Looking at the graph they seemed to run out of puff.

 

Just thought about this. My SBC-iD was set to have a warning and cut off at 16.0 psi.

 

Therefore it may not have been the tubs that run our of steam rather than the controller limiting the boost.

 

Looking at the psi graph I got, I hit 16.0 psi on my controller (16.6 on their gauge) @3800rpm then it dropped to about 15.5psi then hit 16.6psi again at 4600rpm, then slowly dropped to 14.7psi by 6800rpm. Would have be interesting to do another run without the limiter on to see when the fuel starts getting lean and when the tub's run out of puff.

had a good day here, will be going back up as the guy really knows his stuff. Was good to meet the guys there, tho a lot of people i didnt recognise, so put a few names to faces. 188bhp was pretty much as i expected (not in the league of the turbo boys, but not bad for my NA).

 

Looking at the above threads, the fans couldnt have been that bad as Stu, John and Alex pulled some big figures before they detted, so anyone who detted before that has to agree it was their car. I think the guy who was running it was erring on the side of caution in a lot of cases, for which everybody has cause to be thankful. My graph shows the car is still pulling at 6733 Rpm and he stopped it , so I dont feel so guiltyy thrapping the nads off it now (not that I did before anyway). :)

Problem on mine was just running out of injector duration at 5500rpm.

After the initial run which overboosted a bit I pulled it back to ~15psi peak. With the second map I wanted to try, AFR is ~11.3 which was where I was aiming until 5.5k then it just leans out, even though the maps are still trying to put in ever more fuel at that point.

Initial det at higher boost was at 3~3.5k, which coincides with the turbos coming on song and peak torque so I'll look at what can be done about that.

 

I think there's some truth in the fans not getting the I/C properly as I'd run with the first set of conditions on the road for ages with no det (and you would have heard this, believe me).

Also, I guess the RR can hold load at a given RPM longer than you can ever achieve on the road so you probably hit engine conditions you never see there either.

Erm... my car didn't det at all even at 16.6 psi ;) (must be my stillen front bumper :p)
