Yet Another 300Kw Sleeper

[sexual harrassment panda]

Ok so I've had 300rwkw+ for the last 5 months and thought I should post up here before the next tune.

A bit about the car

july '07 bf mkII xr6 turbo in lightning strike -zf gearbox, stock height, stock wheels, no turbo badge

Best time so far at the townsville strip on FEDERAL 595 RSR

reaction - .505

60ft - 2.111

ET - 12.488

Mph - 113.92

mods

custom tune by Cape York Automotive cairns

Herrod intank fuel pump ($500)

60lb deka's (picked up still in the packet for $360)

Centre muffler replaced with twin hotdogs ($100 2nd hand)

F6 lower snorkel and k&n filter

Turbo flapper mod and 12psi actuator (ex QIK1)

3" Hurricane cat in stock pipework (ex QIK1)

DDS monza style intercooler (ex QIK1)

Flash tuner version 1

King springs and monroe gt shocks up front - stock ride height

stock rear springs/shocks

27mm front and 22mm rear whiteline swaybars

Front lower control arm sponge replaced with nolathane bush

Attached are 2 dyno sheets - 1 mainline and one dyno dynamics

Hey Sideways, cant tell you enough how good it is to see more sleepers getting around . Also I live the 2 dyno sheets and the comparison between the 2 , looks like dyno dynamics is reading higher but the difference isnt as much as I was expecting (thought it would be about 10kw diff) did they say what the deal was with doing the run in 3rd?

Thanks power_slide, on the sleeper front I forgot to add that the intercooler has been painted black too.

I know dyno's and tuners can be a touchy subjet with some so I posted both. They were both done in the same month, at the same time of day, in the same city, 3 degrees different air temperature. With all the possible variables with strapping down, tyre pressure, intake temp probe etc etc the result was both were within 2% of each other and 1% of the average for the two. These two shops are the only places in cairns people take turbos too.

Both of these shops do dyno runs in 3rd for the ZF gearbox in the turbos, I believe it is a safety thing with 4th gear getting to 230 (apparently ) at the revs the dyno dynamics printout goes up too.

Aiming for 340rwkw without increasing the boost, hopefully by easter but possibly june.

Here's mine from the other day. Had the car tuned by elite auto in Brisbane with 337rwkw so you can see the difference in being up here in Townsville.

Pete's dyno reads accurate to for all the sceptical people out there. Had my blown ute previously from Brisbane and dynoed from within a few kw of each other on both dyno dynamics.

will post up my tune from Brisbane's elite auto when I find it.

The drag strip read correct with my mph (112-113mph) then as the first run on the dyno was the 318 then within the minute backed up with 297 then after about 5mins idleing with the big fan blower and minus air filter (testing to see difference) did a 301rwkw.

So either the Rapids intercooler is crap dropping 20rwkw or another factor is there.

$speed auto also, BA mk1

Here are the other graphs with boost and afr's-

Dave from mackay tuned my car in 3rd too, I think it's just a tuners preferance thing. I'd like to see back to back runs done in 3rd and 4th to compare rwkw and torque consecutively. Think I might get him to do it, next tune, just so I can see wat the difference in readouts is.

[power_slide]

I would be keen to see that

[sexual harrassment panda]

bjc - I'm even further north, both those runs were in cairns but I'm in innisfail. If I lived in townsville I'd drive to see Dave in mackay. I'm not to sure what you mean by "The drag strip read correct with my mph (112-113mph)" is that with the brissie or townsville tune.

I don't know much about the 4 speeds what is normal for their mph vs hp

Were both those tunes with the same mods? 13 degree ambient temp difference too.

mattyb - your plazmaman stg1 kit is still sitting in my cupboard and I just bought an exhaust off here too. that's why I'm aiming for 340rwkw without increasing the boost, hopefully by easter but possibly june.

Yeah the same tune has been in the car since I left Brisbane, I even re-flashed it before the dyno runs at TMS to see if I had accidently loaded the 2nd tune in by mistake as it has the same boost but with 2degree less timing.

Dave was the one who suggested I drag it to see what MPH it runs as like he says that's the true testoment to what power you have.

When I told him I ran a fastest of 113.06mph he said that's about 300rwkw and not the 337rwkw, should have been around 115-117mph.

Just got back from seeing Dave a couple of weeks ago now, had a friend take his new fg xr6t down to get some work done, he ended up with 318rwkw also and only dropped 8rwkw with back to back runs with his PW stage 2, PW 4in intake, 60lb inj, PW surge tank and bigger cat on the standard system.

Dave said the exhaust was holding it back and that the intake alone only netted about 5kw over standard as the stock exhasaust system needs changing to work hand in hand.

Forgot to mention I haven't had it tuned up here. The dyno readout at TMS is with the brisbane tune. and ran at the drags here in Townsville.

Dave will tune it for me when I get around to fitting my PW surge tank, port and flow the wastegate hole (keeping stndard flapper) and buy a 8psi actuator.

Will also get Dave to fit 60lb injectors as I only have 39lb ford motorsport injectors that eugene was selling ages ago so not sure if they are close to maxing but the bigger ones will give me more headroom anyway.

Also looking at changing the rear muffler on my 3.5in xforce system as Dave also said its restricted, which it is. I looked into the tips the other day and they taper to like 2in! also looking at a gutted cat but dont tell the RTA.

I'd be happy with about 330rwkw but for it to be as reliable as possible so that's why I am doing all the little things to get it sorted.

on the difference with 3rd to 4th on the dyno, my car had an 8kw difference on back to back runs with 3rd reading higher. This was on a Mainline dyno done in Mackay on a humid day.

[sexual harrassment panda]

well it's booked in for a tune in a few weeks, a couple of bits of gear to go on.

Plazmaman stage 1 intercooler kit - stealth black of course , intercooler pictured below. Custom 4" dump and cat reduced down after the cat to mate up with a twin 2 1/2" Xforce stainless exhaust. Both the intercooler kit and exhaust can support 380rwkw with the right mods, but with the f6 airbox and keeping it to a relatively safe boost level I'll be happy with 340. I figure gaining 15kw from the cooler kit and 15kw from the exhaust puts me around 335 to 340rwkw and that will do me nicely. Should be coming onto boost a fair bit earlier too and have more powaars all through the rev range. Might have to ramp up the boost a bit slower to help with traction in third and to save my tyres/license.
