That's the 1, it was so new when I got it in September Andy didn't even have the software to map it.

The ignition cut instead of fuel cut is very handy as it helps prevent det if you hit the rev limiter, which is quite often on my RA gearing and 7000 rpm rev limit

Launch control as well what more do I need to say, and only about £50 more
than the standard Power FC

Graham I'm not to concerned with the low figures at the moment, my Scooby hasn't really been used since it was mapped in October and I'm getting married next weekend so that's my priority at the moment, but when I'm back from honeymoon I will definately be looking for more bhp and far more torque. I'm not selling my purple beast for a long time so 400 + bhp will come sooner or later, most likely not on this engine though. Just rember power is not everything though

How did it go Graham?

 

The car made 373bhp, dont know the torque figure.

 

Just got back and ran a few errands, so here are the details:
1
The Facts:

373 bhp @ 6333 rpm
318 lbft torque @ 6100 (200 @ 3500)

Bad photo but here's the sheet:



The day was realy good, and I met many of the visitors to this thread, very nice to meet you all! I think today proves I'm the Oldest modified Impreza owner!

I was 17th to run, though 7 dropped out allowing the 6 reserves to run which made me feel better.

I had the chance to see how things were done, and I'm well impressed with the Well Lane people, very considerate, careful and consistant.

Then it was my turn.
Spent 5 mins rewarming the engine and then onto the roller (first time for me).

Strapped down, the RR driver slowly moved through the gears, 1/2/3 then at tickover in 4th away we went. What an experience. Never seen the car running so to speak out of the drivers seat.

The din is great, the fright is eye popping as 6500 arrives and the car is 'singing' soooooooooooo smoooooth, even i was impressed.
5 runs later and I'm getting used to it

'just hit 407 bhp' screamed someone as I think a thousand eyes stared hard across the RR to see the graph climbing....

I must admit to being a bit proud as the car (to my ears) sounded bloody fantastic, so hard edged and solid (BIG thanks to AndyF)

Average of the runs gave the above results and I was well pleased, and so seemed many of the Audience too!
I take stock that David Wallis thought it a 'good run' and 'sounded right' from one who knows. Rich Wilde was impressed, irritating to see his car (on after mine) run 378 bhp...but 310 lbft. Ha!

So, after all the rush I cruised home down the M1/M42 in fifth.
the car now only needs 2 gears, 1st and 5th so solid is the torque, overtaking is magic, and to proove that I'm an (old) boy racer, the faces on the lads in the 106 GTi by Sheffield was funny, for the split second I saw them as I 'cruised by'.

Sorry.

Here are some random snaps of the day.

This is the end of Phase 2 for the development of the car. I still want the torque up to around 340/350, so will search-out some ideas soon.

Thankyou to Andy and equally to all of you who have helped me so much with advice and encouragement. 8 weeks and £3000.

Be warned.






Graham.

 

Well done Graham good result, looks like I will definately need to find my missing bhp and torque now

Colin.

 

Well done Graham. Nice figures there mate. Colin, shall we organize a trip oop North to Well Lane then?? Sure our missing ponies will magically appear then

 

A very well done to you Graham, you must be delighted.

Will type more later, tea's up!

 

Well done Graham,
So your very much on track(pardon the pun)in regards to your initial targets.
Identical torque figure to mine but i had a bit of slip., seems W/L rollers were reading a bit low on torque?

Carry on the good work

 

nice one mate
Good to see your hard graft (and pennies) have been well spent

 

Remember, the car sounding 'solid' as you put isn't solely down to Andy, the chap who bolted it together deserves a pat on the back as well.

Sounds like you had a fantastic day out. I bet all that time spent in the garage freezing over Xmas seems worthwhile now? It all kind of makes me wish i'd gone in a bit more gung-ho tbh. I can't help but draw comparisons between our 'projects' - next time the budget is going out the window for me.

Are you sure about trying for more torque? I'd hate to think you were chasing numbers. At your age you should be wiser than me. If Andy's correct in thinking the WL rollers are reading low in with respect torque there may be more there than they say? I know mine certainly feels as though there is more torque there, even though the rollers said it hadn't changed from last time. I'm sure this isn't the placebo effect either as the car pulls comfortably up hills it would never have done before FETD05 + remap.

Anyway! I'm looking forward to hearing how you get on this season.

 

Graham, nice to meet you. Well done on the car, looked and sounded excellent.

Steven

 

Could be the cheapest option I might need 2 or 3 tanks of Optimax each way though coming from Southampton

I might keep quite on this one as I don't want to be blammed for starting another South vs North vs Scotland bhp war

 

I still want the torque up to around 340/350, so will search-out some ideas soon.

Well done graham.
You should be delighted with that, I know I would be.
Your only 12 short of your Torque target and +13 on your BHP.
Personally I would leave it at that instead of throwing more money at it, Unless you can get the extra torque your after through the Apexi FC or other minor adjustments.

Andy

 

what bar of boost was the car running on the rollers

 

Well done Graham. Good thing it's not producing much torque your gearbox might last a bit longer

Mark A

 

i gotta get my 16`s powder coated dark grey

so the power was over your expectations but the torque was lower,

what would you rathe rhave for hillclimbing, the power or the torque?

 

Not sure if I believe the torque figure ? The car certainly doesn't feel like the peak torque arrives at 6500rpm on the road
The airflow and injector dutys suggest max torque is nearer 4800-5000rpm.
The graph shows a linear increase in torque up to 5500rpm, on the road it feels like the torque arrives hard around 4000rpm then increases slowly after that, tailing off slightly from 5500.
What do you think Graham ?

Andy

 

nice result Graham always knew white ones where faster

 

The Commander registered a peak boost pressure of 1.47 bar, where that occured I havn't a clue.
Cruising back home it showed a peak of 1.5! (that boy racer incident)

I am going to leave it alone now, and go racing.

I would prefer the car to have more torque (gearbox aside) BUT, and this is where it counts, the pull is superb from 4500 to 6000, exactly where I need the grunt, pulling out of very tight corners having changed down a cog or two.

On saturday afternoon I moved the turbo actuator on its mounting bracket to increase the 'preload' on the wastegate flap.
Andy and I thought the flap might be leaking at high boost; don't know if this might have helped the blower keep 1.4 bar?

One thing I did notice is the inlet hissing is very high on accelleration, not a leaking noise, but very induction hissing (IYKWIM).

Anyway, it goes like the clappers
The $$ have all gone
And the season of racing starts in 4 weeks time.

But I've seen some very nice wheels I fancy, but no brownie points in the bank...


Great day, and I didn't sleep last night thinking about it and such a public 'display' of the results.

Definitly one of those special days.(and Carl is right, the cold nights are forgotten/forgiven)

Graham.

 

Just seen your note Andy.
I totally agree.
The pull is so strong from 4500 to 6000 it is very luring, and Points Earning!

The rollers had just been re-calibrated apparently, so, maybe there is something there.
Several cars had a wide difference between power and torque, where on a good engine they tend to be quite close, ie 300 x 280 or 290.

I realy am dead chuffed with the car now, so will leave it well alone, BUT, Andy, if you get to the Midlands 'area' please let me know, I may go for another tweek in the summer.

Graham.

 

Flat:

Only white ones with DARK wheels!

Surprisingly, mine was the only white Impreza there! Must be a first.

Graham.

 

i'm going to try and test the theory with blue wheels also

 

Whats the deal with the average figure being given out ? I would have thought that cars with top mounts should have been given their highest figure as the tmic just cooks after the 1st or 2nd run and the power figures drop right back.

 

So that's the answer.

 

Well done Graham great results

 

Graham, congrats !!!!!

Were u able to sustain the 1.4bar of boost at higher rpm ?

enough talking, let the racing start

Carlos

 

When she has calmed down, will take the wife for another ride out to watch the Commander closely while I do a 3rd gear run checking the boost level v rpm

If power is torque x rpm simplistically, then at 373 bhp the torque must be pretty good at the top?

Andy, I believe the runs were avaraged, rather than the best run only is printed?
I was curious to see the power drop off so quickly at 6600 as the red line is 7800 before cut sets in.

I think the operator shuts off as soon as the graph starts to dive.

Previous graphs I've seen, mainly of non turbo cars, show the torque graph to rise and run almost horizontal to the peak rpm, but those are Porsches!

Graham.

 

But the power doesn't start to dive?

I think he just assumed 7000rpm limit, it looks like the power dives as the operated lifted off the throttle!

Paul

 

great result G!
well done!
much catching up to do now methinks

 

At Well Lane the 'driver' watches the graph and lifts when it dips he isn't watching the tacho, we put Jim Littens car on at the end and we got him to call out exacly when he lifted, the tacho (and hence graph showed) showed about 6100 but the Link logs showed the lift off closer to 6400, peak torque on Jims graph was about 5100 (UK car), I suspect from the boost profile that we missed peak VE/torque by a fair amount.

The torque figures did seem a little lower than usual yesterday, losses of 20lb/ft over previous runs seemed common whilst bhp was there or thereabouts compared to previous runs.

Rich is the person to ask for comparisons of course.

Good to meet you Graham, and, echoing what others have said the car looked and sounded great, amazingly quiet and smooth for such a powerful machine.

Andrew...
