I've never seen or heard of a 16G making that sort of power.
Anywhere between 320 and 340 is achievable.

 

Td05 16gs make more power on evos. My cousins makes 402bhp on td05 16g. No fuel additives. But he has had cams/head work done

 

Well my evo did and so did quite afew others on the early evo owners...

mind you my car did have afew mods...

2.3stroker kit
fully forged
hks 272 cams
hks pulleys
hks rs suction kit
walbro
syntec fpr SET at 3.2bar
510cc injectors (standard)
mines ecu
greddy profec b set at 1.3bar

300whp 317ftlb atw guess it depends how you work losses...20%??

my next mods were to 20g and larger fmic and 750cc...but life got in the way!!

 

Where are you buying your HRC pumps from?

 

ebay is good.

 

using a SARD 255 fuel pump here, no issues yet

http://www.scoobyworx.com/swrd-255lp...-pump-26-p.asp

 

As above ebay. Its direct from hrc. Im sure it is. When I bought it from ebay im sire sellers name was hrc something

 

Email him. His name is Rob.

enquiries@hrc-performance.co.uk

 

Cheers Guys

 

My 255 is more than up to the job at 490bhp! Buy from trusted sources.

 

So are there any issues running an uprated fuel pump on an otherwise standard car?

Only asking as mine has recently failed and am just weighing up the options... car is a Classic 99 UK Turbo.

 

You'd need to get the fuel map checked.

 

hrc have seemed to dissapear from ebay. whats the scoobyworx ones like?

like here.

http://www.ebay.co.uk/itm/1212028303...84.m1423.l2649

 

Have you emailed HRC ??

 

no. just read an old thread on here. apparantly the scoobyworx pumps are hrc ones anyway so ill probz order through scoobyworx.

 

HRC fuel pumps are not SWRD pumps just to clarify. Scoobyworx used to deal with HRC Performance until releasing SWRD 255lph and 290lph fuel pumps.

 

swrd pumps look decent though to be fair.

 

what you reckon on this??

http://www.ebay.co.uk/itm/2812036768...84.m1423.l2649

 

I wouldn't.

Buy one that is a well known brand and tested, and also from a trusted seller as advised above.

Rather than saving a couple of quid bite the bullet and buy a well known pump from a trusted seller.
Buy cheap buy twice is a phrase said often and listened to not often enough.

 

Two reasons to upgrade.
1. A standard pump will flow a enough fuel most of the time on a modified car. It is when you give it beans the standard pump can not flow enough fuel at the top end. Hence why you need a pump that will flow more in that situation. A225lph will do the trick for most people.
(As well as the usual suspects also consider american stuff like these http://www.deatschwerks.com/products/fuel-pumps)

2. Fuel pumps get old. If it fails - engine goes bang. So swap out for a new one once in a blue moon from the safety perspective not the performance perspective.

To echo Shaun I ran a Walbro 225 at 450hp with no problems. And do not buy from Ebay

 

Just as if not more capable than the vf35's IMHO.
I've seen a hawk on a 2.5 make 350/400 on a 16g at SRR.
Good little turbos.

 

Most are just re-branded sytec (walbro) pumps.
Even the HRC's are based on Walbros but modded to their specs.
The SWRD ones come with a Subaru style sock so I'd be tempted to go with them.
A mate bought a 340lph RCM one, and for the money he paid I assume they also modded theirs too. Either that or their packaging comes at a bloody premium

 

Supplied with wrong sock filter for a subaru, can cause stuttering when below 1/4 of a tank of fuel

 

If you change the fuel pump to an uprated one from a standard classic WRX, do you have to change the injectors and the fuel filter as well? Also what about mapping, will the car need re-mapping just because you changed the fuel pump? If you don't have to change the injectors as well

 

No need to change the injectors unless you're planning a power hike. Fuel filter doesn't need changing because of fitting a new pump but should obviously be done as part of your service schedule.

It wouldn't hurt getting your car on the dyno though just to make sure its running sweet. Its an old car now so checking things like the fueling can only be a good thing.

 

Cheers for that Matt and if I could afford to get it checked out properly mate, I would. Its the worse scoob I have had so far I have spent roughly £1,500 on it and nothing really to show for it

 

Unfortunately as you evidently know these aren't normally cheap cars to run at the best of times.
However saying you can't afford a £40-50 diagnostic run on a rolling road sounds a weird thing to say - if you can't afford that dude one might argue you bought the wrong car to begin with...

Personally I didn't get mine checked after changing the pump but that was because I was told by my mapper I wouldn't need to (and in fairness I was getting it mapped a few weeks later anyway)

 

Oh I got the idea and thought Matt meant about a map not just a check up, so too speak
