On The Rollers Last Week

[kidafa]

Hi all,

Had my 1997 RSFour on the rollers last week. Just thought Id post up the graph with a list of mods so we could maybe start a cross referance or something to see how eachothers cars are running and with what mods.

As said above mines a 1997 RSFour Mods are as follows:

• Splitfire Coilpacks
  
• HDI Frount Mount
  
• Profec B spec II EBC High boost set at about 11psi
  
• SAFC2
  

Was dynoed in RWD (front tailshaft removed)

I had my 98 RS Four S on the Dyno a week ago for a couple of power runs. It has a GCG Hi flow, CES Racing split dump, high flow cat and a 3in cat back exhaust. According to the guy doing the Dyno it was hitting Boost cut at 14psi.

Good for a starting point I think. At least now I can go from here.. Forgot to mention it was done on an all-wheel drive Dyno.

I do need to post up my graph, and I saw nick post his today too. will update this thread when i post it elsewhere

mine was done on a 4wd dyno, 155kw

power mods are

power fc

12psi boost

turbo back 3" exhaust

splitfires

walbro fuel pump

standard intake, intercooler, injectors, afms etc etc. oh and manual conversion that probably gives me a couple of kw without the slushbox.

sssstagea you need to get a computer and tune asap. the standard computer responds very poorly to mods - 130awkw is not right for a highflow turbo running 14psi....your setup should be good for 170awkw+

looks like all the stageas have good midrange but poor top end compared to a skyline motor - fits with mark's theory that they have small cams compared to 33 gtst. we are going to do some back to back test with r33 series 2 cams shortly.

Comes back to the same 'rich retards' idea that I was getting with mine, I could feel the car pushing against the 'glass wall' because all the timing had been pulled out by the ECU and as soon as the engine neared the redline it was like a switch was flicked somewhere and all the timing came back for a last minute 'kick' before going back into slug mode again.

I can't see your graph. Could you post up the KW please?

you might have to shrink the photo file size.. max is 8mb

How are you regulating your boost? I guess you are on a budget like most of us or else you would have a Power FC or suchlike already but I would recommend getting a Jaycar Independent Electtronic Boost Controller or if you are just bypassing the solenoid reduce the size of the restrictor to lower boost. Mr car made 155AWKW (200bhp) with the stock turbo on 10.5 psi and i would expect to do quite a better with a GCG highflow. Have you still got the standard side mounted intercooler? If you car is a series II then maybe you already have the GTT SMIC otherwise that would be a worthwhile cheap and simple upgrade. There are two or three aftermarket options for the SMIC and I was luck enough to find a cheap second hand Trust one. But maybe first upgrade your fuel supply (pump and regulator) if you haven't already.

hi guys im just wondering if you guys who have put up dyno results of your stags are you running autos or manuals?? and are they s1 engines because the power figures seem to be a bit low for a neo . my 99 S2 RS4 stag with just a 2 1/2 inch exhaust turbosmart boost control , BOV and 5 speed manual with 10 psi ran this

Yep your neo has a slightly bigger turbo and possibly different cam timing from my Series I auto which made 155AWKW (see above for chart). But when I install my IEBC etc and give it a tune I expect to get quite close to your figure.

Perhaps someone with access to FAST could compare the part numbers.

Sorry I can't tell you much about my setup due to only owning the car for about 2 months and not knowing anything about Turbo setups. The guy running the Dyno said that it hit boost cut at 14PSI, not sure if this is what it is running at all times. As far as I know it hasn't had anything done to change boost but looking at everything on this site it must have. I need to find someone that can point out any changes to my setup cause I don't know what looks normal and what doesn't. After reading through this site and getting myself confused on aftermaket engine management I ill also need to go to a workshop or speak to someone who can point me in the right directions. Would really love to find out more about if anything else has been done.

Going to the Gympie skidpan day so will talk to some people there and see what they say.
