Took my car to Bob today very happy ,the result was 370 bhp 400 torque

The only mods are RCM induction ,straight through centre on exhaust

Bob said the good result was down to bigger turbo

Happy days Glenn What turbo is on it?? I'll give you a bell in the week

Fantastic figures there Glen I was not expecting that

Very impressive indeed, goes to show how good that car is to start with.

How can he tell you what power you're running? Good result btw

That is a flat out run in 4 gear from 1 500 to 7 00 on is laptop differant to rolling road then all rolling roads are differant

Nice one Glenn, Bob really knows his potatoes and can get the best out of your car.

TX, Bob uses Deltadash to calculate the bhp/trq achieved and by taking car weight, wind resistance and a load more factors into account can calculate the results gained.

I hope to be back up with Bob before the end of the summer with a new turbo and a few further mods and hope to achieve just under 400bhp.

STI Glenn

Had a chat with bob about your car TY said you where going at it BIG time

Cannon Fodder

iTrader: (100)

I have a lot of time for Bob, he is always on hand for advice and help.

That figure of 400lbs/ft torque is tremendous for a 2.0 litre engine it must pull like a train.

Can't wait to get my car sorted with the new turbo, uprated injectors/fuel pressure regulator/fuel pump, RCM induction kit, new headers and a remap.

Fantastic Glenn, what a car

The Stitcher

iTrader: (12)

but how dose he know the weight of the car ?? as some will be lighter or more heavy depending on what has been done stripped or added so it's not a true reading but close

also depends on road conditions and wind as it could be against you or with you so cant see it being the same everytime and think if you use a set of rollers just use same one's all the time

ty why didn't you just get all your bits and just map it once it would save you alot of money

STI Glenn

Very true Lee but it is really a standard car nothing added or removed ,any way rolling roads are no differant unless you use same one every time same weather

The Stitcher

iTrader: (12)

only change you would get on rollers if using same one's could be temps in the room

it would be interesting to see what it would make on rollers and also see what the difference would be but it is a good result if that is true

plus it looks great mate

Had my car mapped by Bob last year, deltadash made it 319bhp 325lbft, Had it on enginetuners dyno dynamics and it made 322bhp 320lbft, so not far out.

He knew the weight of the S202, added the weight of the fuel, his installed equipment, my weight, his own weight plus Simon's weight (RF555) who came along to see what it was all about.

I was definitely not carrying any sacks of spuds in the boot so I would say that his measurement would have been accurate enough. The spreadsheet I have of my last mapping session does actually have a box which must be used in the calculations which I think is a drag co-efficient.

Besides you can get some major variances on rolling roads as well, such factors as ambient temperature, whether it is a closed cell or not and even the height above sea level/atmospheric pressure I have seen a debate on.

Plus the different manufacturers as well all seem to read differently as well so perhaps even rolling roads have their drawbacks.

I was going to keep the car as is and get rid of it for a UK 2.5 Hawkeye or Hatchback a while back, but I have decided now to keep it due to its rarity value so I have decided to 'eek' a little more power out of it.

Besides enough is never enough...

STI Glenn

Anyway the way it drives is the main thing ,and the car is fast enough for me cheers

thats the main thing glenn

i know mine wont be pushing out much when we go to our RR day soon as i only have fastflow headers and straight through system on it and a sti panel filter

but it will be intresting to see how far from standard it is being 16 years old

your car is stunning fella whatever the power

The Stitcher

iTrader: (12)

i agree mate think that it is a very good bhp gain just from an air filter and exhaust around 50 horses and 80lb-ft more than standard just shows what can be achieved with the right parts and mapper

Driveability is the main thing in a car. Horsepower and torque are irrelivent in my eyes. Yes it's nice to have a car running 400bhp and 400lb ft of torque but pointless if it's rubbish to drive.

well done glenn ex results there

I agree Calv, would be tasty having huge power but as you say if it's a rubbish drive what's the point if a big power car is spinning on gear changes etc, then it's standing still and less powerfull cars - putting their power down effectively, will go past the spinners, unless a lot of gizmo's are fitted like launch control etc - drivability has to be the word (or was that Grease)

Great results there Glen I was happy with my results from Bob too. I didn't get a delta dash done, but the car feels fast enough for me. I think sometimes we all get too wrapped up in figure chasing, its nice to know how much BHP/Torque its making, but its not the be all and end all. If anything i'd like to concentrate on refining the power on mine by reducing the lag a little. Functional ALS is my thoughts for the future maybe a change of intercooler too.

It's an OEM fitted turbo to the S204.... if it is available on any other models I could not tell you.

One very important fact not to forget is the lack of mods to Glenns car, RCM cone and centre section only... it just goes to show how good a base OEM model this S204 is and how little you actually need to do to it to hit such figures

STI Glenn

It is a bigger turbo than Spec c think vf 46

Hiya Glenn,

do you mind if i ask who fitted the cone and exhaust. (its Ben from the trading estate)

Here we go dug some info out...

IHI VF42
This is the standard equipment turbocharger used on the JDM Subaru Impreza WRX STi S203 and S204. The VF42 features a twin-scroll design with a slightly larger compressor than the VF36/VF37 turbos and different turbine design (more blades). The VF42 is a roller-bearing turbo and is similar in size to the VF22 turbo, but the twin-scroll exhaust housing yields faster spool-up and a superior top-end.

STI Glenn

Cheers Si i went on Google but could not find info

Ben James at ti 21 in beechwood ,i have a Pipercross induction for sale if interested

Good results Glenn

The VF46 isn't a bigger turbo than the VF37 but runs a revised 5-arc twin scroll setup allowing for better turbo response. A VF37 on a spec C will produce 370 bhp but due to being slightly less responsive and the engine torque output tends to be slightly lower at 370 Ib/ft with minor modifications. The VF46 is found on the limited edition USDM legacy spec b after replacing the VF38 twin scroll with titanium compressor wheel.

You can buy these turbos for $925.00
