The car will be going no where near a track Just don't want to wreck it!

With the 650 injectors and an FMIC will it need to be mapped again and will it be ok to fit said items before mapping???

cheers,

gav..

 

Gav,

The car should really be remapped each time you uprated something significant.

I have a set of Power Enterprise 650's coming in the next couple of days, although I cannot fit them until just before the car is back with Bob in early October for the required remap.

If you can wait until then, im sure Bob will be more than happy to comment on whether that particular make are any good and work ok in the car.

One thing I am doing, is getting a set of AST's and the rest of the T25 suspension package as the chassis is struggling to keep up with the power.

 

"On track" not on track ...

Hol the PE's will be fine I've mapped loads with those fitted.

cheers

bob

 

Brilliant this thread is going again! It's got a much faster pace to Shaun (the webster) articles. I think his artilcles are about where Bob was but just a couple of years difference

So lets progress and learn something new with the twin scrolls

 

Ohhhh AST's, i'm very very tempted by the group buy on these. I'm down at PowerStation on monday too, will have a word

cheers for the advise guys. Hol you've got yourself a beast of a car there. Just slightly ahead in the modding stakes, will be twins soon

 

Gav, you beat me to the AST's at least


Got back from Powerstation and then Bob yesterday.

I had the AST/T25 full set-up fitted in the morning and a remap for the 650's in the afternoon.

Im hoping that Bob will be along to provide some technical explanation later, but suffice top say, Im glad I had the suspension upgraded

The car is now fitted with a special version of the Ecutek software only available for JDM STI's (sorry UK peeps!). Basically this allows the car to have (what amounts to) - individual maps for each gear

With that and the 650's running at 81% duty*, the car really flies and is noticeably quicker on the road through the gears. :Thumb:

Considering how easy it is to drive and how good it now feels, I don't know if I even want a bigger turbo. (famous last words).

Kent Scoobies have a RR day ar PE, where most of the results have been measured on the 25th November. So Ill have to wait until then if it has actually gained, or if the in-gear software just feels like it has.

 

not fair....

 

Nice one Hol she must really fly now.
Can't wait to see the RR results.


Dave

 

Sorry Mark! - Its to do with the way that the JDM STI wiring works.

Dave, It feels so much quicker through the gears , but I honestly do not know if that is power related to the bigger injectors, or a benefit of the new software. Even I will have to wait until the RR.

It is getting 1 bar of boost at around 2900 rpm though

 

I thought it was already mapped to each individual gear? Or maybe I was thinking of boost?

 

Hol, if you don't mind me asking, where did you get the heat reflective material to go around your FMIC pipe work ? and what brand/type is it.

Looking to do this to my pipe work.

 

Get it right.... my car was producing 370bhp (on the standard turbo) WITHOUT water injection, induction kit, FMIC or funny fuel concoctions. Now go back and add up the price of those mods and then tell me how far behind I was.

When are people going to realise that peak figures dont mean squat in isolation in any case.

Hol and Bob,
Glad the project is alive again and hope you progress as you wish to.... looking forward to the results as this is what these threads are all about. Good luck!

 

Excellent news mate!

Increases in driveabilty cannot be gauged by RR printouts alone! Your car is already quick, so dont go chasing BHP figures for the sake of it and dont be dismayed if your RR figures have not changed much.

Regards,
Shaun.

 

Thanks Shaun,

Im enjoying every minute I can at the moment.

Last night I was out 'just driving' when I came accross my old next door neighbour in a new Evo, doing the same thing!

Cars SHOULD be all about the driving experience and not the looks.

 

IIRC, Bob got 370bhp on exhaust/induction and remap back in 2003/early 2004?

 

That was with a splash of NF on top of the optimax, if you read Bobs commentary.

I think Shauns point is that he has made gains with the hybrid and plain pump fuel.

 

I'll post up the comparative Deltadash plots of the car when I got those figures compared to the last session, there is quite a marked difference.

I'll also put some info up on the "Mega-rom", its not something to use lightly BUT given the right car and enough time it makes a big difference, only usable on JDM cars though. Not normally included in a normal remap cost btw for reason's of time needed.

The larger injectors have stabilsed afr's at the high rev area and the individual boost control maps (all 10 sets of them, 5 pairs of maps twice over, thats 20 in all) has allowed for absolute boost mapping in each gear, 5th/6th are run off a common set.

In addition we have two complete sets of ignition and fuel maps plus two sets of VVT maps to boot, oh forgot to mention the two settings for off boost closed loop afr and the launch control now has launch retard added (1 bar boost on the line anyone ?).

So true map switching from the oem ecu, previously only boost maps were switchable.

V Nice

cheers, more later

bob

 

So who is this ' launch retard ' then so we can spot him?

Or are you referring to my efforts last Friday??

David APi

 

Thanks for the technical update Bob.

'Mega Rom' - Such a cool name....


I certainly don't think he does mean you

But, is it better to be a launch retard that one of those late clutch 'dumpers'??

 

Actually David could be included, think it was 0.7 bar on the 2nd launch attempt David ?

Hol the graphs are done but will upload tomorrow and email them to you as well. I have graphed saturdays effort and related it to the last DD run I probably did at 377 bhp.

bob

 

But you did say that it is mapped at 1.4 bar. so I'm only using half of it then ??



David

Owens are making me the 1.4 bar waste gate actuator so we should off and running again soon.

 

That as well , but I just wanted to readdress the facts that what had been achieved on my car for circa 370bhp, was on pump fuel with standard turbo and no induction kit.

Bob,
Sounds very very interesting!

 

Sorry matey,

Didn't mean to be rude, but have just noticed this.

YHPM

 

Ok hopefully the comparison should come up, bear in mind this comes from DeltaDash Road Dyno software, its generated by accellerating from low revs up in the chosen gear, weight, gearing, tyre size, frontal area and drag coefficient are all factored in, a rolling road can rarely emulate the actual real time conditions and so rolling road torque is nearly always lower. The "spiky" nature of the curves is down to DD's sampling ability. These curves are power and torque at the wheels, add 22% loss back to each to get flywheel power, before is then 377bhp and 396 ft lbs, after is 396bhp and 416 ft lbs.

 

Excellent results there Hol.

I am having a complete blonde moment. What is the sum for calculating the transmission losses?

 

Excellent work Bob and Hol!

Bob,
Would you or Hol mind sending me those Road Dyno performance files, as I would be interested to see the differences across (if there are any) over the whole range. As the peak figures in DD are nigh on the same as what I had acheived earlier on this year....... tis a good bit of kit this DD is'nt it.

Regards,
Shaun.

 

Shaun,

All I have is the graph. Bob is the man to ask.

Id be interested to see what the comparison is to your hybrid if you do it as the turbo is now the limiting factor.

But, I wonder if people realise that it is all down to the front splitter.

 

Hol,

roflol regarding the front splitter.

It's a tough comparison as the conversions are not like for like, but it's still a comparison and interesting to see me thinks..... hence the question about getting access to the file.

For info though, when mine consisted of:

Standard turbo
K&N Panel Filter
Uprated Actuator
3 Port Boost solenoid
ECUTEK on Optimax

It attained 302bhp 325lbft in DD (obviously at the wheels).

DD with he hybrid gave a tad more.

As known by others, the vehicle weight entered in DD can skew the figures somewhat so I weighed mine on API's scales and always run the car in the same format as weighed (full tank of fuel etc) for DD to ensure the best chance of accuracy. Looking at various graphs that have been published from the US, it was always interesting to see what the vehicle weight entered for the run was (easily known by dividing the peak BHP figure by the BHP/ton figure shown on the graph)..... it's all then very obvious where inflated figures come from (falsely increasing the entered vehicle weight can dramtically over egg the at wheels power figures).

All these comparisons are very interesting though and it looks like your car is very quick!

Regards,
Shaun.

 

Weight used for the run we took last week was 1680 kg, car plus fuel plus a load of suspension (four struts etc) plus Andy.
car weighs about 1450, I weigh about 67, fuel at say 40 kg, suspension at say 18 kg and Andy at about 105 kg. Vehicle weight taken from Subaru specifications.

testing Seans's comment re weight fiddling ...
at 1680 kg ... 308.9 bhp and 324.3 ft lb - 183.9 bhp/tonne
at 1650 kg ... 303.9 bhp and 318.7 ft lb - 184.2 bhp/tonne
at 1700 kg ... 312.2 bhp and 328.1 ft lb - 183.7 bhp/tonne

so not a huge impact, playing with wheel size give a more stealth effect.

bob

 

Bob,

True.... magnitudes of 20-50kgs do not see much difference, but I have known people to wallop oin in excess 150kg's to bump the figures up on some of the other forums across the pond.

Regards,
Shaun.
