Hi all

just had the scoob with john @ pro-sport for a checkover and rolling road to see how my mods have done or whether they were a waste of money!

Well good news and not so good.

not so good news was the best it ran was 257.1 bhp
but the good news it has 302.6 Lbs of torque! (well i think thats good!)

Car spec: 1993 wrx import
Z4 ecu with scooby ecu chip to 15.5 psi to run on optimax alone
HKS Induction kit
Hks fuel cut defender
JW racing manual boost valve
HKS downpipe
Afterburner vortex angled back box and centre pipe
Blitz iridium no.7 plugs

I do have a problem with hot air being sucked in, anyone know where i can get a direct line feeding the induction kit or know about putting somthing to seperate it from the engine with some alli? or could i mount the ind. kit elsewhere?

What could be my next sensible step for more power!?!?!

Oh & i have all the afr/knock link/oil press./boost gauges, walbro up-rated fuel pump, upgraded brakes & s/steel lines, eibach springs, anti-lift kit, top & bottom struts, new arb's front & back & new links for them, 17" alloys, full samco's, forge header tank

Any how big thanks to John & the lads at Pro-sport for a top job and giving sound advice - highly recomend them!

Sorry to go on, any ideas on the above, much appreciated
Cheers, tim

You should be overjoyed with that torque! That is a great result IMHO.

There are several 'inthe front wing' induction kits now to get the coldest air to the engine, API make a sexy one ($$), but check the various Project threads (you should make a habit of that now) and you will see some good ideas/results, especially 'Flat4' thread.

I would leave your engine alone now and get the suspension/brakes done.

Good luck and well done!

Yes Prosport are a top place and they look after you too.
John cant do enough to help, makes a change for a garage to be like that.

A bit like my 2004 WRX wagon which has 269bhp & 300lbs torque, does anyone know why certain cars can produce loads of torque yet others struggle

TonyBurns

iTrader: (3)

Mine is 311bhp and 331lbs of torque (just an STi panel filter, JDM STi MY03 btw) then again it was designed to have higher torque levels than most other STi's (except of the same year onwards )

David, it was early....It was an APS so sorry!
Been decorating the hall and got those light switches crossed too...fuses are fiddly things to fix (in the dark)

Cheers for the reply 911

I will have a scout about on the induction side of things, it seems to make quite a diffrerence this hot & cold air thing!

Timmy did you notice my P1 at Prosport when you were there ?
it has a "P1" number plate

See it! see it! i wanted to buy the bloody beast!!!

Well nice motor, you are a very lucky person mate!

What is yours there for?

oh and what is that exhaust system, i thought mine was loud!

I didn't know John was running the place now, does Pete know?

Interestingly (maybe ) my car has always had higher BHP than Torque at Prosport, although generally cars do seem to put down good torque figures there. I know from my own datalogs than boost comes in earlier than on other rollers.

Andrew...

Pavlo

power does seem very low though, especially as the turbo is capable of spooling up nicely. The combination of scoobyecu, fuel cut defender AND boost controller is an odd one though.

it's not a wagon is it?

Paul

NotoriousREV

My very similarly specced MY93 WRX did 288bhp on Prosport's rollers this time last year. IIRC, it was something like 288bhp @ 6250 and 250lb/ft @ 5500

pavlo, i have my graph print out infront of me and there are 2 bhp readings.
the first is 257.1 bhp and has Peng next to it at 6920 rpm

the 2nd is 317.4bhp at 6350 rpm, this is also shown on the graph that it hits 317.4 bhp. & has Pmax next to it.

I would put it on but cant work out how to insert the pic!

Its a saloon!

My WRX03 was serviced at Prosport today. Very good service as usual... they even washed and vacuumed it.. BONUS.

Saw a blue P1 in there today i thinks. Big backbox... think it had AP racing front calipers.

Fastfrank that is not my car( I pick it up on sat )
but the car will be there 2morrow ( tues) as the Motec that I had fitted is playing around with the fuel injection
Richard Bulmer will probaly remap it again

Hi tim, the exhaust is the Blitz Nur-spec
had 550s,VF34 turbo,Gruppe-S headers and a Motec M800 fitted to make the "beast " a bit quicker ........ as I did not like the tek3 along with the MD304 turbo that was on b4 ( but still make 342 bhp ! )
with the motec and vf34 they had got the car to around 400 bhp, but now they have detune it to 380 ( to save the clutch and gearbox while my wallets recovers )

Mike

Pavlo

So it made 317hp!

Hey paul

could you explain these to figures to me?
The 'Peng' said 257.1bhp
but the Pmax said 317.4bhp which is right/wrong?!? im confused here!

The graph clearly shows the torque & bhp figure - torque showing the 302 and bhp hitting 317 at that rev, before it goes down to the rev limit which is where the 257 figure comes from.
hope that makes sense!?

oh & i have decided to try & put my induction kit behind the cut outs in the bumper (not sure if will fit yet!) & run a pipe (any ideas on what & where from appreciated!) up to the original connection of where the kit should be.

Anyone else tried this?

Pavlo

I think the Peng is probably the power at peak RPM, but it's entirely down to the software as there is no clear nomenclature for rolling road graphs.

I suspect the Peng is possible the power at the point where the cursor was on the software when they printed the graph. The rolling road operator will lift the throttle as he approaches the redline to begin the coastdown loss part of the power run (whilst also dipping the clutch).

Paul

thanks paul, kinda makes bit more sense!
so does this mean that my car has the 317 or 257 bhp though (sorry to seem thick!) what do i class it as if i am asked!?

Pavlo

Your car has 317.4hp !

Paul

AndrewC

The printout should have PWheel and PMax figures, what are they?

I would leave the induction kit where it is but run some cold air feeds to it and try to shield it from engine bay heat.

Andrew...

Pavlo

Andrew,

the 317.4hp is the Pmax figure

AndrewC

Aha, should have read all the posts first, but still interested in knowing what PWheel is (and PLoss for that matter).

Andrew...

What boost are you running with the Dawes fitted???? Mine has similar mods but just running on a ScoobyECU 16.5 psi map and got 285 bhp and 260 lbsft.

timmyajmy93wrx

iTrader: (27)

from what i can see at a glance it runs 18-19psi

not had chance to go on a long straight & check properly yet, & didn't think to look on the way home from pro-sport down the motorway!

Andrew the Pwheel is 266.5bhp & Ploss says 44.5bhp?
