What bhp would that give me as I don't no what these are standard?

get urself a hks BOV aswell mate can't have a turbo without a dump valve its the law lol

fingerscooby

uprated fuel pump, get rid of the cats if not already done so, what air filter? green panel? Then start looking at turbo upgrade, front mount intercooler, decent spark plugs these are worth changing, nice and cheap. Just some ideas, its never ending really , enjoy emptying your bank account like i do ha ha!!!
Try and get the remap like steve777 rightly advises after you have got as many upgraded parts as you can afford or else its false economy, just my opinion.

Is it sti or wrx as this info needed for best advice

Gonewrongmark

K/n cone filter. Dump valve. Been told the pump is ok to bout 400ish bhp as it's the 2.5 turbo lump.

You ideally need a high flow fuel pump for higher power, such as Walbro. The standard STI fuel pump (assuming you have STI) "might" be ok but it is better to be safe than sorry - inadequate fuel supply means you may risk detonation. Do you have the WRX or STI? As said above, get a decat downpipe, and remove the 2nd cat too, and finally custom remap - that should be all ok to do under £1k, and with the WRX will net around 280bhp on its turbo (I might be wrong on this figure with the WRX) but on the STI hawkeye you will see a nice 350ish bhp figure with those mods. The standard "recirculating" dump valve (bov) is more efficient than the aftermarket "dump to atmosphere" ones, which make the noise.

wrong wrong wrong, basic mods should be the turbo back exhaust, panel filter, walbro depending on ur goals or how old the standard is and ofc a remap ( duncan springs to mind )
why on earth people insist on dumping metered air to atmosphere is beyond me

Gonewrongmark

It's the wrx . What's the standard bhp in 1 of these?

Pramas

hawks are around 227 or somthing like that, with the basic mods above u should see around 270 ish, depends on turbo and each car is diff

Gonewrongmark

Nice 1. Can't wait for the mods to begin thx

With Panel filter and good decated exhaust plus remap you will more benefited like from Cone filter and you will see around 270-280bhp..

forgot to mention methanol ! its way cheap 67p a litre vs vpower but ofc will need a map for it, but bhp vs cost is hard to beat

Methanol is nice,but he will need run everytime on Methanol,because he can't have switchable fuel maps.

But i doubt he will make more than 310bhp with methanol.He will more benefited from fitting bigger turbo VF43,VF34,VF35 and decatted exhaust and remap than Methanol.


Jura

Pramas

the step up to a vf43 etc is consdierable more than £1k since you need suporting mods in place alrdy, am certain he would enjoy it but meth on a tdo4 will see a nice cool running engine and extra bhp, it is a bit of a pain should you do alot of miles but if like me you dont, its not an issue, just carry a 10 ltr jerrycan full in boot should you need to refill a full tank on your journey, and say he got an extra 30 bhp ( 280-310 not sure how acuurcate that is ) its a small price to add on

Def a remap. Will really set it free on what has been done so far. The std map is pretty lame and is a wonder they sold many of the cars. There is so much potential untapped.

The td04 will max at about 280bhp but torque can be up to 340 lb/ft and that is a huge improvement over std.

Remap : £350
Fuel pump £75

If you want over 300bhp then something like a VF35 gives great grunt with not much increase in lag or for around 340-350bhp a VF43 or VF48. All of these can be got for around £250-£350. Add an sti tmic for about £100 and it will still come in below the £1000 budget.

Hi Duncan. Andrew (Yorvik) is very please with his Hawkeye that you mapped yesterday! Said it goes like stink but still quiet like standard. Must be odd. Haha. He is over the moon with it by all accounts! Nice job again!

dynamix

Yeah it is a real sleeper but I think he has come to the same conclusion as you re the brakes lol. I was told not to mention impending brake upgrades in front of his wife

Hawkeye wrx gearbox is stronger than previous wrxs and can easily handle whatever the td04 can throw at it and most likely all that a vf43 can throw at it with mechanically sympathetic driving.

They do go very well once mapped.

Did one for subaru4you yesterday 288bhp 350lb will post graph later.
Also ecutek racerom is nice touch with two maps, launch control, throttle blip and flat throttle shift etc.

Standard fuel pump is perfectly fine, especially when still on standard turbo.

Haha. I’m all brembo’d up now thank god! Even my uprated wrx brakes were just not good enough!

By the way, why do you think he was getting more air past the MAF than I was? Considering changing my Do-Luck panel filter to a cosworth one. Heard mixed reviews about the Do-Luck. Also, does that point to possible MAF problems for me or am I just being critical?

His turbo was holding slightly more boost at the top than yours - nothing more than that. Will be interesting to see it on the dyno shortly (will be sorting a day out to dyno / tweak a few cars up that way) to compare what that air translates to power wise.

Nice result Simon

Cool, thanks mate. Makes sense actually. My vf48 is 20k miles, his was new and mine has slight crack in exhaust housing.
