Everyone tells me with my mods i should be running more bhp maybe 320 mimimum with these mods can any one tell me what the problem is and why im down on power or ANY way i can diagnose it !!!!!! with the below mods im running 298.7 bhp
this is the mod list i was given when i bought the car
no mention of a uprated fuel pump???????? could this be the problem????

2.0 WRX
VF35 turbo with Forge uprated actuator. Turbo ported on hot side and wastegate to avoid boost creep.(£300)
Pink STI injectors(£100)
Cosworth filter(£35)
STI intercooler(£120) with Bug STI bonnet scoop and undertray.(£130)
Cambelt and tensioner replaced approx 1k ago.
Re-map by dynamics

Exhaust:-
Japspeed up-pipe(£20), std headers, Prodrive sportcat(£120), prodrive second cat delete(£50), de-resonated centre pipe(£50), STI Genome backbox. (£250)


ANY IDEAS id like to hear some ideas why im so down on power

has you mapper not provided any ideas or suggestions as to where it appears to be lacking??

most obvious one would be an over-size up-pipe??

Where was power measured?

Road mapped or rolling road mapped?

To be honest, with that mod list on a WRX, I'd have thought 298 was not an unreasonable result?

Is that a wheel or flywheel figure and as mentioned was it on a RR, if so which one as some are overly conservative on their figures. I would have thought 330-350 at the wheel would have been a good figure with those mods assuming everything is working as it should. Maybe try and get hold of an STI up-pipe and fit that instead of the japspeed one

As per your last thread Uppipe it's too big and yes get an uprated fuel pump

An equivalent STi would make IRO 325/310

And perhaps it needs a fresh pair of eyes over the map ?

Ok chaps, long time no see.

I happened upon this one so thought I'd fill some gaps. I had a walbro fitted before the first map. I was a bit concerned about the japspeed up-pipe when we fitted it, but at the time I didn't have an STI up-pipe to drop in. I did offer it to Kerry when he picked the car up but understandably he didn't want a load of pig iron cluttering up his garage!

If you guys have any other questions to ask to get to the bottom of this, feel free. I'll not be on too regularly but I'll keep an eye out.

Oh and it is a Prodrive sportcat.

Can you post the power graph?

It's on the other thread, Simon.

Quick copy and paste though.

Just a thought, and not accusing anything here, but as you havnt had the mods done yourself, have you actually checked it has the parts on the list you were given fitted?

8 months ago?

Theres another thread, thought it seemed familiar

iTrader: (41)

It's quite a lazy curve.

I very much doubt the OP travelled up to the Co. Durham, to put the car on the dyno, Simon.

Printout will be from when Myles was stationed up here.

it does look laggy whcih could well be down to the uppipe if it is a bit of a large diameter (its a cold day looking at the temps on the graph so would expect it to spool well) but normally doesnt normally effect power that much but both power and torque are a little lower than expected but by similar amounts... peak power is fairly low in the powerband..

Very true. Lisa and I went down to High Wycombe for a night on the drink a couple of years ago.

Its a fair question, the buyer takes the risk when presented with a list of upgrades on a car. I can, however, vouch for each and every component that i listed on the sale thread. I bought, 90% of them on here so I could probably trawl back and dig up all the threads.

I was happy enough with the performance, but Kerry is looking to go to the next level. It is apparent though, that the next level is actually the upper echelons of this level (if that makes sense!)

My advice to Kerry would be to spend £20 odd on an STI or classic up-pipe, swap it out, then get a mapper to look at it. It's the only way to be sure.

@JGM, I posted this dyno printout when I had it done, and the same kinds of comments about the curve were made then. I was happy at the time, Kerry has every right to get it right for him as the new owner.

Jesus, did you bring your stab vests.

hey myles havent got your number log book FINALLY arrived ! im going to try get a new up pipe fitted soon but just had spend big on new clutch..........wasnt the actual clutch you had fitted as when removed i see it amnd had loads of life left it was a seized spigot bearing which any case clutch ,box,flywheel etc had to come out so ijust replace the lot..........also new brake shoes and 4 new tyre as i got new rims which i post a pic see what u think

kezwaldo

it had 215s when i bought wheels and looked stupid so now we have 4 bridgestone 225 looks better !!

kezwaldo

the sti wheels just wasnt to my taste and wasnt in the best condition so went for these they are immaculate even the insid eof the wheels are clean as if new .........what do we think myles i just wanted to put my own little stamp on the car ! not that it wasnt beautiful anyway lol

kezwaldo

anyway myles ddo you know what size up pipe the jap speed was????????? maybe i need a smaller one?

Why are you selling up ?

Myles

iTrader: (40)

I'm afraid I don't. Surely Japspeed will know though.

53

iTrader: (41)

More than likely 2" which is 7mm too big for that spec to spool tight and tidy

kezwaldo

i was selling up when i had the clutch problem but now its been sorted at no extra charge i will not be!!! i thought seeing as id placed add id see it out see what sort of interest i get for the future if i sell. BUT THE CAR IS GOING NOWHERE LOL

kezwaldo

if i already have the car mapped how much is it going to cost to remap once up pipe is fitted....because if its 60 for uppipe and a further 500 for remap id prob leave as it is.

kezwaldo

also myles has my car had a blob eye rear conversion (lights ,bumper etc) its what people keep saying???

Myles

iTrader: (40)

Yeah, have a look at the blob rear ends. The lights are subtly different.
