RICH WILD

Hi,

Yesterday's dyno day at Well lane produced some amazing results for my car.

It's a 97 UK turbo and I'm still using the standard ECU and injectors, albeit with a FCD and an electronic boost controller set at 1.35bar

I hit 386bhp and 317lbsft.

And that is without a front mount, just on MRT uprated top mount.

All that was changed from my last run of 344 was the OEM headers ported and wrapped, stainless Jap Innovations uppipe and Jap Innovations new backbox and a tad more fuel pressure.

Special thanks go to Jap Innovations for all the work done on my car so far and also to Harvey for porting my headers for me and to Andy F for providing the turbo.

Thanks also to Harvey and Andy for all their free advice too. They have both been a great help.

I think if I'm not mistaken that that is the highest figure I've seen on a top mount and also the highest figure I've seen on 380 injectors too. I can't remember what Andy got with his car on the 05 turbo but I reckon it's the highest figure for an 05 that I've seen too.

Is this a record?

What AFR and fuel pressure are you running?

well done!
I guess this answers the question in my thread if porting standard headers is worth all the hassle.
Is there any instructions on how to do this lurking on SN?
Thought there were heat problems with wrapping standard cast iron headers or is this an urban myth?

Dan.

RICH WILD

Thanks guys,

John,

fuel pressure is 3.2 bar at idle with the vac disconnected.

Not got exact voltages for the afr, but it runs to the last green on the lambdalink to the redline and has been checked with a wideband lamda in the tailpipe and it runs up to 10.00 and holds.

Knock activity is 2 greens max.

Dan,

urban myth I reckon, but I wouldn't like to say for sure as it's not something I've heard of. Ask me again in 6 months.

Cheers

Rich

Adam M

so you are running raised fuel pressure then.

I hope so as I was a bit concerned givent hat 380s are supposed to be limited to 300bhp.

flat4

mine lasted 2 years before i sold it, going to do the same on my current project aswell

MorayMackenzie

Impressive figures Rich. Do you have a dyno graph you can post up?

AndrewC

At atmos this is not much above std.

I assume 1.35 bar is midrange, what boost is it holding at peak power?

Nice increase in torque since last time, I guess you notice this more than the top end.

Andrew...

MorayMackenzie

Also, is it really just 3.2bar fuel pressure with the ref line disconnected? I would have thought it would need to be ~4bar on a fixed rate fpr. Which begs the question, what sort of adjustable reg is it you are running... is it the FSE rising rate job?

Fredysan

Congratulations Rich!:

Some time ago we send a couple of mail about get some good power and torque figures (over 350 HP) without using bigger inyectors and Remapping the ECU. I see your goal was accomplished... Now, what is your next step?

By the way, Do you still have the stock gearbox?, I guess could be useful you tell us about the way to have the stock gearbox with that figures. At the other hand, What are your ET times? I don't have dyno here...

Regards from Chile

blue-scoop

how much did it cost to port the headers and who would you recommend to do the job?

colin c

Excellent results Rich I'm glad to see your still trying to push the boundary's of Scooby tuning without chucking loads of money at it like most other people.

Looks like I wasted my money buying 550cc injectors and only running 319bhp I know Tweenierob made over 400 on standard headers is this your next aim ? So your useing a TD05 / 16g with straight entry not 1 of Andy's TD05 / 20g turbos ?

I'm going to have to start spending some money on my purple WRX, I was about to order a set of Gruppes headers and then send my old TD05 to Andy for a 20g conversion, but I'm tempted to hang fire now with the headers and see what I can get just on the turbo alone because I still love the sound from the original headers

Hopefully see you at 1 of the shows this year, Colin.

RICH WILD

Adam,

Yes the fuel pressure is slightly raised and the old 300bhp thing is purely a guideline and shouldn't be taken as written in stone as I have now hopefully proved beyond doubt.

Moray,

I do have a graph, but no scanner. I'll happily fax the graph to someone who has though. And yes it is 3.2 bar with it disconnected and it is a rising rate jobbie.

Andrew,

It peaks and holds 1.35 to the redline. Re the headers, you could FEEL the difference as soon as they went on. Car felt more responsive to the throttle and after 5000 rpm the extra urge was very noticeable.

Fredysan,

Yes I remember. Next step is to now stop spending dosh
The gearbox is standard UK MY00 after my original one went bang.
Don't have any ET times as I've not subjected the car to a 1/4 mile day yet.

blue scoop,

Talk to Harvey Smith. He did it for a very reasonable sum, especially considering the gains.

Colin,

Hi there, and thanks.
Wouldn't say you've wasted your money, they'll come in useful someday I'm sure
I'm still on the 16g FE, yes but I'm all done with modding this car now, it's my everyday car so I need to keep it reliable. The insanity is going to be poured into my white one now. Give Harvey a call re headers before spending your money.

Yeah, hopefully see you at Billing or something.

Cheers

Rich

The "rising rate" FSE seems to actually be 1:1 like standard, so with an extra 0.2 bar of fuel pressure you could expect 3.3% extra flow on top of the 380s, so you are only using 4.1 cc fuel per BHP. That is incredibly efficient.

I am using 70% IDC on 740s at 0.5 bar over standard and making 403 BHP, so my efficiency is only 5.6 cc per BHP.

I don't know how you're doing it with so little fuel and why it doesn't lean out.

When I ran a 16G on 550s at 90% IDC with loads of booster, ported headers, FMIC and 1.5 bar at 6000 RPM it only made 358 BHP P-eng, again 5.5-5.6 cc per BHP.

What is going on? Are Subaru engines really that fuel efficient at 10:1 AFR?

MorayMackenzie

Hi John,

I made it 4.066... cc/bhp at 100% IDC... I suspect that to get 10:1 all the way up it must be a rising rate rising rate reg.

Moray

john banks

If it was a genuine 1.7:1 then at 1.35 bar it would have 4.6cc/bhp still very impressive.

carlos_hiraoka

If you were using a MY97 TMIC then it is a record ..... if I am not mistaken the highest figure with a TMIC was Bob R's STi ver 5 .... although I am pretty sure we will begin to see very good results of the new STi ver 8's also with a TMIC.
Wonder how will this car with a TMIC perform on a track ?????

Carlos H.

Fuzz

**** on the same figures as my 00MY, could you send me the graph once you have got it into the PC, I'd host it for you too if you like ?


Well done Rich

Andy

carlos_hiraoka

long time ago a guy who logs under "NITO" installed an HKS turbo, FMIC and boost controller and got very interesting results with a stock ECU and 380's .....

Carlos H.

john banks

326 at PE you mean?

carlos_hiraoka

yep ..... I know Andy F. got even better results, but he used xtra fuel / methanol injection IIRC.

326 bhp @ 6800 rpm 275 lb/ft @ 5960 rpm on SUL



Carlos H.

carlos_hiraoka

Rich are u still using the stock fuel pump ?????

Carlos H.

Andy.F

NICE one Rich

Not sure if it is a TMIC record, Xavier in France is making around 395bhp on a TD05/06-20G fitted to his Sti7 with TMIC.

As far as I'm aware however 386bhp _IS_ a record for the TD05FE on a Subaru I had previously made 369bhp on a TD05FE at Star Performance using a charge cooler, std ECU and 380's.
Don't you just love it when they say it can't be done

Andy

RICH WILD

Thanks for the feedback everyone.

Yes Andy, I do love it.

I seem to remember almost exactly 2 years ago in Feb 02 when I got 320bhp in my white car at Well Lane on standard UK internals (Harvey will remember that), apparently THAT "couldn't be done" either. Now 320bhp is nothing.

Didn't they once say that getting a man on the Moon was impossible too?

Just messing fellas, nothing meant by it

Carlos, my full spec is in the Northern section under the Well lane thread. Yes it's the standard pump with a restrictor to limit fuel supply for better economy

Cheers

Hi Rich. A tremendous result and a great tribute to Nic.

It shows that where Scooby tuning is concerned, conventional wisdom is sometimes bunkum.

RICH WILD

Thanks Harv.

Nick would have been pleased with 300. That was his goal. I think he'll be smiling from ear to ear now.

Cheers

Rich

RICH WILD

Quick message for John Banks,

I just realised that I haven't had the car widebanded since the headers were fitted. The 10:1 figure came from before that when it was running 344bhp or thereabouts.

Does that make the maths any more realistic?


Rich

AndrewC

Don't you have an EGT gauge? Has the temp increased at all since fitting the headers/uppipe?

If it has leaned out at all you would expect a noticable increase in EGT at these power levels.

Andrew...

john banks

Rich honest answer is that being that rich would tend to reduce efficiency and make it less realistic, implies less airflow in that you can actually get it that rich with that fuel system. However, if that is an AFR from a previous spec it is not so useful - you might have gained presently by leaning out from that. A narrowband won't tell you in much detail where you are from 10-12:1 with much repeatablity and absolute accuracy.
