I have just had my wrx blobeye remapped with the following mods:-

Reconditioned VF35 with new turbo smart adjustable actuator

550cc injectors

TGV delete

Decat downpipe and genuine STI decat uppipe

uprated fuel pump

3 port boost solenoid

STI top mount

uprated spark plugs

run on v power

(don't think I've missed anything off the top of my head)

compression tested it before I went ahead with the remap 165psi on all cylinders, gearbox sound, clutch sound, cars healthy.

car has only managed 306bhp and 275lbft at 1.2 bar is this normal figure?

Now I thought the general figures from what I've seen and heard should be roughly 320-340 bhp and 300-320 Lbft should I be dissapointed and contact my mapper regarding it?

I understand that it's just figures it's how the car drives but this seems very low to me.

any input would be appreciated.

Suppose it depends if the mapper knows what there doing.

I tend to go off how they drive not chase numbers.

Like you say,if it drives well then that's the main thing,figures seem on the low side but a safe 1.2bar. I'm sure the mapper could of squeezed some more power out of it but maybe they like to be a little conservative/safe?

Any graphs to show?

Seems a bit low, but VF35 is not really a very good turbo, which is why all the STI boys get rid, nothing much happens until 4k rpm must be a dog to drive on a WRX without avcs.

Do you have a print out? seems a bit low but try it on a different rolling road and you might get 320... Ive never used a vf35 but thought that they spooled pretty quick. Im using a vf48 on a V4 sti and it spools way before 4000.

Who mapped it?

ossett2k2

iTrader: (9)

I've also always thought of the vf35 as a very fast spooling turbo capable of around 340bhp

ditchmyster

I'd say it depends what you're used to, I had the VF34 (ball bearing version for those that don't know) on my V3 STI Type R, but between the cams and the short ratio box it went like a bat out of hell and that was with a mere 330bhp, and that's a 360 bhp capable turbo, had it dialed down for the sake of the gearbox.

Yet Jake above had one on his WRX and thought it was slow spooling and swapped it out for a Hybrid TD04 which I think is much more suited to the non avcs WRX engine, something that is backed up by him now being a happy man.

As above though, it's not all about big numbers, as I'm sure you'll agree.

A vf35 will spool quicker than a vf34 but the 35 will run out of puff while the 34 will pull all way to end.
35 come off a avcs car anyway so running with non avcs don't expect same.

plus your getting on the limits of the wrx drivetrain at 330-350

jf12345

Here's the graph, don't want to say who mapped it though but 2 knowledgeable guys at a reputable company that's been doing it for over 10 years with basically no complaints, think I will give them a bell Monday because the figures are underwhelming roughly same torque as a remapped td04.

dosent feel much lag to be honest just a bit more then the td04

My 05 wrx is 100% stock , apart from a little map tweak by a few mates . 108k on the clock , drives perfect . Running 271 bhp on tdr rollers , i would expect to see more than 30bhp+ more than my car with all those parts on the engine ?

Was it a quick flash map and go or was some decent time taken doing the remap?
Have you got boost and afr graphs? Thought you said it was 1.2bar max
That graph says 1.5bar.

this ^
and its certainly not laggy at all. the figures do seem low even without avcs pushing it along tho. ive seen blobs mapped with those kinda mods and generally they see 330+. if it was done on a rolling road then most of them show different results anyway. it also says 1.5 bar final at the top of the sheet? you said it was 1.2 bar but if it is mapped at 1.5 bar then its really struggling to make power

It's clearly gr performance by that graph

Lol you are good
Betting shop pen not the best disguise but still you got eyes like a hawk corky

jf12345

It's a proper custom map, not a flash, was told new actuator set at a safe 1.2 bar, and like I said not naming no names, the cars spot on and everything no problems, just looking for a bit of advice/guidance off you knowledgable chaps whether you guys think it's a bit too low? And worth to chase it up.

Depends what you class as laggy.

Hated my vf34 round town. Holding second gear to stay in boosts crap

Looks a very safe map which gaz does tend to do and generally relies on boost to make power rather than ignition timing. On average a vf35 should see around 320-330

Uncle Creepy

My old WRX made 297/305 on a standard TD04, which I appreciate is the exception rather than the norm on that turbo. But, still, your figures do seem very low. With those mods, I'd hope for roughly 330-340 of each and full boost by 3300-3500 rpm. Do you have a boost graph?

what's the remainder of the exhaust system?

rickybobby

I thought the boost solenoid set the boost, not the actuator? I currently have the standard vf35 on my blob sti, with only a 2.5" decat and APS induction kit and it makes 336bhp 330 torques at 1.5 bar.

I did have it mapped but at the 1st attempt the actuator was found to be weak, so I was told to get a 1 bar actuator and the boost solenoid would then take it to 1.5 . It now holds strong all the way through the rev range.

Based on your mods and graph I'd agree with the others and say that its a safe map and not really getting the best from what you have, but I've never owned a wrx so dont know how much difference being without the avcs would make.

Best of luck with it

power is about right for the boost and non avcs also boost is moderate as some mappers run around 1,35 - 1.4 bar

If the op still has the oem headers, they will cause a restriction regardless of any changes downstream

bustaMOVEs

iTrader: (31)

Oem headers will be fine up to 350, it's after that will cause a restriction

trevsjwood

iTrader: (2)

That's not what I found being just about in the same position as the op stuck on 300hp

ossett2k2

iTrader: (9)

Should be hitting peak torque well before 4800rpm,higher torque and bhp with stock headers.
But it probably is a safe/conservative map,not sure if that's what the op asked for but that's what he's got.
I'm sure if he asked the mapper for a more aggressive map then that's what he would get.
Timing is king

jf12345

Standard headers, 2.5" centre section to a prodrive back box.

so if the boost solenoid does this I could have just bought a standard 1 bar oem one for £100 quid less and used that.

ill post the boost graph a bit later when I'm at home.

I've just got my **** handed too me up too 130 mph by a mk5 golf gti with a sticker that said stage 2 on the back which I'm guessing is about 270- 280bhp not happy just slowly pulling away from 40 up to 130 he was a good 5 cars lengths Infront this was on a straight (private) road foot planted, very surprised.

nothing a explanatory phone call won't sort I'm sure, just wanted opinions.

Is it safe to have a vf35 set to run 1.5 bar all the time..

ossett2k2

iTrader: (9)

1.5bar might be a tad to much to get the best out of that turbo,1.3-1.4 imo is safe,running too much boost can have a negative effect.
You need to look at other parts of the map to get the best out of the car/package you have.
You have to remember,every car is different so you may well be getting the best of what you have,nobody really knows as we haven't remapped it.
Air in and air out,VE,all have an affect.
Timing has a lot to do with power/torque output,so either get the mapper to run some more aggressive timing or buy a bigger turbo.

trevsjwood

my VF34 was always run at 1.4 bar. Running more boost doesn't always = more power and I've always found the mapper gets pretty much what's available on the day.
Is that back box the one with twin tailpipe?, Probably not, just trying to remember what was on mine 8 or 9 years ago when I was going through all this
